Begin the path of immortality from mortals

[Book friend 'Fanfanfantuaner' 1 rewards plus chapter*]

Xuanzhen Palace.

Inside the side hall, there was a waft of spiritual incense and the fragrance of spiritual fruits.

Black Phoenix King Xiaoguan saw that Lu Tiandu and the Cave Sky Rat King had become familiar with each other after her introduction. She knew that Lu Tiandu must have something to discuss with the Cave Sky Rat King, so she took the initiative to speak:

"Friend Lu, Friend Kong, now that you two have met, I will go meet Sister Duanmu first... After you finish talking, I have something else to discuss with Friend Lu!"

"Okay, thank you very much for this time, Brother Xiao!"

Lu Tiandu stood up and bowed slightly, "After I finish the transaction with Daoist Fellow Kong, I will entertain Daoist Fellow Xiao!"

As for the Cave Heaven Rat King Kong Jie, although he was doubtful about his old friend Xiao Guan bringing him to Xuanzhen Palace this time, he did not show anything. But when he heard that Lu Tiandu wanted to trade with him, he became more confused.

After Xiaoguan left, looking at the puzzled Cave Rat King, Lu Tiandu smiled and said:
"Fellow Daoist Kong and I have never met before. I'm sure you are also confused about Lu's talk of a deal, right?"

"Daoyou Lu has made a name for himself in several clans over the years. I have heard of Daoyou Lu's name for a long time. I didn't expect that Daoyou Lu has a good relationship with Daoyou Xiao..."

The Cave Heaven Rat King spoke in a rough voice, and looked at Lu Tiandu with deep yellow pupils and said, "It's just that Kong and Fellow Daoist Lu have never had any intersection before, but I am a little confused about what Fellow Daoist wants to trade with Kong. If I can help Fellow Daoist, Kong will not refuse."

Although because of the relationship with Xiaoguan, the Cave Rat King was not afraid that Lu Tiandu would have any bad intentions towards him, but facing the notorious Lu Tiandu, Kong Jie did not want to offend Lu Tiandu because of something.

Speaking of intersections, in fact, when Lu Tiandu was in the human world, he also had an intersection with the Cave Heaven Rat King's clone, the Tianlan Holy Beast.

However, from the previous communication, Lu Tian knew that the Cave Heaven Rat King probably didn't know about the transaction he had made with the Tianlan Holy Beast in the human world, so he didn't mention that the two of them had some old history.

"Don't worry, fellow Daoist. This transaction is a win-win for both of us."

Lu Tiandu did not keep the secret any longer and said directly, "Daoyou should have a page from the Golden Palace Jade Book in your hand, right?"

"What? Did you make a mistake, fellow Daoist? How could such an immortal item be in the hands of a mere mid-stage fusion cultivator like Kong?"

Upon hearing this, the Cave Heaven Rat King's yellow pupils suddenly shrank and he quickly shook his head.

At this moment, he was extremely alert and more and more confused. He really couldn't understand how Lu Tiandu, an ascended cultivator of the human race, knew about the jade page hundreds of years ago.

Not to mention the Black Phoenix King, who had the best relationship with him among the Seven Demon Kings, he had never revealed the fact that he had the Golden Palace Jade Book even to his relatives in the clan.

And how did Lu Tiandu, a human cultivator, know about this?
Weird, really weird!

"Fellow Daoist, there is no need to deny anything in a hurry. This Golden Palace Jade Book is actually one of the inherited treasures of Baizao Mountain, a major human force in the True Immortal Realm. It accidentally drifted to the lower world. I also have a few copies in my hands. As for why I know the one in your hand, it is because I am proficient in certain divination techniques, and I also know that the information recorded in this inner page should be related to the acquired cultivation of the True Spirit Body..."

Lu Tiandu said calmly.

"The inheritance treasure of Baizao Mountain in the True Immortal Realm? Daoist fellow is also proficient in the secret art of divination?"

Upon hearing this, the Cave Heaven Rat King was surprised again, with an expression of disbelief on his face.

It was also the first time for him to learn about the exact origin of the Golden Palace Jade Book, and he was amazed at the accuracy of the information that Lu Tiandu had "divinated".

Although he has not yet fully comprehended the contents of this jade page, he knows that the secret techniques recorded there are indeed related to the acquired cultivation of a true spiritual body.

This made him even more flustered.

After all, he himself has not yet fully comprehended it, and if he trades it to Lu Tiandu, wouldn't he be cutting off his own opportunities?
Moreover, he couldn't damage the jade page at all, so he couldn't use it to make Lu Tiandu hesitate.

"Don't worry, fellow Daoist. I won't kill people and steal treasures just for a secret technique."

Lu Tiandu looked at the Cave Heaven Rat King's unusually alert expression and smiled.

"Whether this kind of upper realm secret technique can be cultivated depends on personal luck, and this technique is not a panacea that can only be taken by one person. As long as you are willing, we can comprehend it together. In addition, according to the information about the true spirit that I know, the prerequisite for practicing this kind of secret technique is to have the blood of the true spirit. I see that you don't have any true spirit blood, and I can help you in this regard..."

"What? Daoist friend, are you willing to meditate together with me?"

The Cave Heaven Rat King was surprised again when he heard this, and stared at Lu Tiandu as if to confirm the truth of his words, "And fellow Daoist has the True Spirit and True Blood in his hand?"

"Why not? This is my friend's thing. I am just trading with him something of equal value. Besides, this kind of immortal secret technique is at least the same as the true spirit level. Even if we get this kind of secret technique, how many people can finally cultivate it? Besides, my friend and I have no grudge against each other. Although I have only practiced for a thousand years, I have rarely taken the initiative to kill people for treasures!"

Lu Tiandu shook his head. "As for True Spirit and True Blood, I have more than ten of them. As long as you agree to share the jade page, I can give you a bottle of True Spirit and True Blood and the method of refining as a deal, so that you can also have the conditions to practice this secret technique!"

"More than ten kinds of true spirits and true blood?"

Upon hearing this, the Cave Heaven Rat King stared at Lu Tiandu with wide eyes. His black hair and beard trembled and he looked stunned.

Only at this moment did he understand some of Lu Tiandu's background. No wonder Lu Tiandu was willing to kill people and steal treasures for a secret technique.

He had asked the Black Phoenix King before coming here and knew that Lu Tiandu was proficient in several true spirit-level magical powers. But now he realized that this was a bit conservative.

Lu Tiandu did not hesitate and listed the names of the ten kinds of true blood in addition to the five-colored phoenix and five-colored dragon.

Kunpeng, golden-winged tiger, yang deer, five-colored peacock, fire phoenix, red bird, pixiu, colorful butterfly, black tortoise, and fire crocodile.

Upon hearing that Lu Tiandu really had the true blood of these true spirits, the Cave Heaven Rat King also realized that his opportunity had come.

Items like martial arts secrets that can be traded repeatedly are indeed a win-win situation for both of them.

However, faced with so many kinds of true blood, the Cave Sky Rat King had a hard time choosing:

"In that case, I agree to share this secret technique with you. I wonder if you have any suggestions for me to choose true blood?"

Since he himself found it difficult to make a decision, he was a smart man and directly asked Lu Tiandu for advice.

"If you make your own choice, I won't say much. Since you asked for my advice, I will tell you directly."

"Although I have ten kinds of true blood, only the Kunpeng and Fire Crocodile bloods are obtained from adult true spirits. The sources of other true bloods are at most at the Fusion stage, and some are even at the Spiritualization stage. To cultivate into such a true spirit body, the higher the level of the true blood source, the better..."

Lu Tiandu said slowly.

He could sense from some of the aura that the Cave Sky Rat King had leaked before that the Cave Sky Rat King should be practicing earth-attributed techniques. However, although he had many types of true blood, he did not have earth-attributed true blood.

As for the true spirits of rats, Lu Tiandu knew very little about them.

He did remember that in the wild realm of the fairyland there was a clan of Tongtian rats who seemed to have inherited some kind of true blood and true spiritual bloodline.

Hearing this, the Cave Heaven Rat King pondered for a moment and asked again:
"I wonder what the blood concentration of the Pixiu's real blood is in your hand?"

The treasure-hunting talent of this Pixiu spirit is well-known. According to the half of the secret technique he has comprehended, if he wants to practice this technique in the future, he will definitely need a lot of resources. With the treasure-hunting talent of the Pixiu, he will have a great advantage in practicing this technique in the future.

As for the Kunpeng blood mentioned by Lu Tiandu, this blood is very suitable for avian demon cultivators, and is very different from his cave spirit rat clan, so he ruled it out without even thinking about it.

If the Pixiu's real blood is not suitable, he will choose the Fire Crocodile's real blood as expected.

"This true blood is indeed much worse. It is only the true blood of the God Transformation level. As for whether you can awaken certain talents after refining it, I dare not guarantee it." Lu Tiandu said truthfully.

"In that case, I will choose the Fire Crocodile's True Blood!"

The Cave Heaven Rat King thought about it and finally said.

As long as he refines the true blood of the fire crocodile, changing the fire-attributed exercises will be a small matter for him. As long as he can cultivate the body of a fire crocodile in the future, not to mention advancing to the late stage of fusion, he will have a higher chance of advancing to the Mahayana stage.

Thinking of this, the Cave Heaven Rat King felt a little more excited and happy.

"Wise choice!"

Lu Tiandu nodded, then he stretched out his hand and a jade bottle and a jade slip appeared in his hand.

With a wave of his hand, the two creatures flew towards the Cave Rat King.

After the Cave Heaven Rat King checked the method of refining true blood recorded in the jade slip, he had already believed it for the most part. When he opened the jade bottle and saw a foot-long fire crocodile shooting out of the jade bottle, he said with a look of joy:

"Daoyou is indeed a trustworthy person!"

As he spoke, a jade box sealed with densely packed spiritual talismans appeared in his hand. He then flicked the jade box open and pointed with his finger, and a silver light flew towards Lu Tiandu.

At this time, the Cave Heaven Rat King pondered for a moment, took out a blank jade slip and copied the information.

"Yes, it is indeed the Niling Zhenyin Great Method!"

Lu Tiandu already had two inner pages and three outer pages in his hand. He was very familiar with them. He only took a quick look at the golden seal characters inside and knew that it was exactly what he expected.

As for this transaction, it was basically within his expectations and there were no surprises.

After seeing the contents of the jade slip that the Cave Heaven Rat King sent again, Lu Tiandu smiled and said:
"Since you have already comprehended nearly half of the content, you can come to Xuanzhen Palace again in 200 years. I will then give you the complete version of the technique."

"In that case, I will wait for good news from you, fellow Taoist!"

Hearing that Lu Tian was confident that he could comprehend this secret art of the immortal world within 200 years, the Cave Heaven Rat King was secretly surprised. It had been more than 500 years since he obtained this jade page, and he had only comprehended nearly half of it.

Lu Tian nodded and continued:
"I think you are not far from the late stage of fusion. If you are still not sure of surviving the thunder tribulation of the late stage of fusion after 500 years, as long as you pay a certain price, I can help you survive the thunder tribulation!"

Five hundred years later, after coming out of the Guanghan Realm, he could at least refine three extreme mountains. Although he could not weaken the thunder tribulation by about 40% like the acquired Xuantian treasure Yuanhe Five Extreme Mountains, but with the power of the three extreme mountains, it would be no problem to weaken the power of the thunder tribulation by 10% or 20%.

Although the thunder tribulation in the late stage of advancement to the fusion is much more terrifying than the great heavenly tribulation, with the help of Yuanhe Jishan, which can not only weaken the thunder tribulation but is also a top-level defensive treasure, it is naturally not difficult to help cultivators increase their success rate in overcoming the tribulation by several times.

Moreover, Lu Tian remembered that in the original plot, when the Black Phoenix King and the Cave Sky Rat King were looking for an opportunity to advance to the Mahayana stage at the border between the human and demon races, it happened that Han Li was advancing to the Mahayana stage, and at that time the Cave Sky Rat King had already advanced to the late stage of fusion.

This happened more than 1,400 years later.

According to his guess, the Cave Sky Rat King was able to advance to the late stage of fusion after more than a thousand years, which was naturally inseparable from the Ni Ling Zhen Yin Dafa. He must have had the practice experience of the Six-Winged Frost Centipede. The Cave Sky Rat King advanced to the late stage with the help of the true spirit body.

He offered to help at this time. On the one hand, he had generally gained some advantage in the previous transactions, so this was considered a good deal. On the other hand, since he would be able to advance sooner or later, he also wanted to see if he could make some money from the Cave Heaven Rat King.

Hearing that Lu Tiandu actually had the means to help cultivators survive the thunder tribulation, the Cave Heaven Rat King felt that Lu Tiandu was unfathomable. However, this was a good thing for him. Some of the costs were naturally not worth mentioning compared to being able to successfully advance to the late stage of fusion. He nodded and said:

"In that case, thank you for your kindness. Whenever I need anything, I will come to you!"

Two hundred years later, if he can get the complete version of the Ni Ling Zhen Yin Da Fa, he will have three hundred years to practice it. Then we will see whether he can use Lu Tiandu's method to survive the thunder tribulation.

After a while, the two chatted for a few more sentences. After Duanmu Jinhan and Black Phoenix King received the message and came back again, Lu Tiandu sent the Cave Heaven Rat King away.

Returning to the palace again, the Black Phoenix King naturally did not ask about the private transaction between the two. Instead, he smiled and said:

"Just now, I heard from Sister Jin Han that you still have the holy medicine Nine Spiritual Ganoderma in your hands. I wonder if I can trade one from you?"

Although Lu Tiandu also invited her and the Cave Heaven Rat King to participate in this auction, it was obviously an auction of the human race themselves. If she could trade for the Nine-Hearted Spirit Ganoderma from Lu Tiandu, as the demon king of her clan, she naturally would not have to hide her identity and compete with other human forces for the three Nine-Hearted Spirit Ganoderma.

Lu Tiandu glanced at Duanmu Jinhan when he heard that. At this moment, Duanmu Jinhan blinked his eyes. Lu Tiandu immediately understood something and said with a smile:

"Since Sister Jin Han has spoken, how can I refuse Fellow Daoist Xiao?"

Lu Tiandu had long discovered that the relationship between Duanmu Jinhan and Xiao Guan was far more than what it seemed, and Duanmu Jinhan had previously expressed his desire to bring the two of them together. In that case, he could just go with the flow.

After completing the transaction, the three chatted for a while. After sending the Black Phoenix King away, Lu Tian remembered the strange look from the Black Phoenix King before, and then he said to Duanmu Jinhan:

"Fellow Daoist Xiao should have discovered something strange about my physique."

"Hehe, now you know that Sister Xiao is still a virgin!"

Duanmu Jinhan said with a smile.

"You!"

Lu Tian couldn't help but shook his head.

After hearing Duanmu Jinhan's words, he could no longer guess the reason why the Black Phoenix King suddenly came within two feet of him. He also didn't know what the two sisters talked about in private.
"Humph!"

Seeing Lu Tiandu's expression of being a good kid after getting an advantage, Duanmu Jinhan couldn't help but snort, "What a playboy!"

……

After flirting with Duanmu Jinhan for a while, the two of them flashed to the Kunwu Holy Mountain Questioning Immortal Palace. The next moment, when Min Yan saw the Niling Zhenyin Dafa that Lu Tiandu traded from the Cave Heaven Rat King, he couldn't help but say happily:
“I didn’t expect that the cultivators in the True Immortal Realm have actually studied the True Spirit Body to such an extent. If nothing unexpected happens, the True Spirit Body achieved through this secret technique will still have some gap in power compared to the innate True Spirit Body, but it will at least have 80% of the power!”

She was originally the remnant of a true spirit. As long as she can cultivate into a true body of a seven-colored butterfly, although it cannot be compared with her previous life, the speed of advancement in her future practice will definitely be far beyond that of a human body.

No wonder she was so happy at this moment.

"Really?"

Now even You Luo became curious and took the jade slip to look at it.

A moment later, after getting the affirmation from Youluo, the complete true spirit, the eyes of the women in the hall lit up, and they looked at the page of the Golden Palace Jade Book with surprise.

Among them, except Linglong and Yinyue who have not yet fused with true spirit blood, the others basically have true spirit blood. If they can really cultivate into a true spirit body according to this secret technique, needless to say, their chances of advancing to the Mahayana stage in the future will increase a bit!
"In that case, Sister Yan, you two should start to comprehend this technique!"

Lu Tiandu had anticipated this and said with a smile.

Min Yan and You Luo are extremely familiar with the body of the true spirit, and have long been proficient in the Golden Seal Script. With the help of other women, it will be naturally easier for them to comprehend this technique, and perhaps they will be able to comprehend it all in a few decades.

As for the two hundred years that Lu Tiandu mentioned, it was just a lot of time reserved.

Time flies, three days later, the auction officially begins! (End of this chapter)
