The Mortal's Path to Immortality

"In addition, what shape and name should be chosen for the communicator?"

Spiritual jade pendant?

Loudspeaker?

Mirror of the Heart? Sound transmission beads?

In the end, Cao Rui decided that the shape should be like a jade pendant for easy portability, so he named it [Lingyin Jade Pendant] as the name suggests.

Remote communication is only the first function. Cao Rui can also add video calls, positioning sending, etc. in the future.

Like the previous fruit, the power is kept and updated slowly, and each iteration causes monks to rush to buy it.

Later, when Cao Rui's weapon refining level improves, and even evolves into an online shopping mall, the Immortal Realm version of Douyin, etc. is not impossible.

In the later stage, if Cao Rui makes a breakthrough in the level of weapon refining and the communication distance reaches the level of communication array, it will basically be the product of Yunzhou Cultivation World's random killings.

Just like the Spirit Ship, the exclusive spiritual tool of the Spirit Ship Sect, once the communication spiritual tool is mentioned, it is the Qing Ling Xiuxianfang.

Only then can you make money.

"In addition, there are the five magic swords of the Great Five Elements Sword Formation."

Cao Rui summoned the golden sword from his storage bag.

The golden sword is engraved with ten first-order magic circles.

There are two types of magic circles, five in each type.

Cao Rui checked the magic arrays on the wall of the inheritance room of the Artifact Refining Academy one by one.

It was found that there was only one type of magic circle existing on the wall, and that was the first-order [Swift Sensitivity].

Five first-level [Swift Agility] No wonder when the flying sword of the casual cultivator in the Qi Refining Stage flew, the speed was comparable to that in the Foundation Establishment Stage.

For another first-level magic formation, Cao Rui found the jade slip of the Great Five Elements Sword Formation and read it carefully. From the refining method of the five magic swords of the Great Five Elements Sword Formation, he found out that this other magic formation is called [Blade] is similar to the first-level [Sharpness], but it is stronger.

It's just that Shenyuan Zhenjun obviously didn't expect that the magic circle that every monk learned in ancient times would be lost now.

Therefore, in the refining method, only the name of the magic circle is mentioned, but there is no specific rune pattern of the magic circle.

"There is absolutely no [phantom] [confusion] of the magic circle on the water sword."

"It is quite difficult to refine the five magic swords of this great Five Elements Sword Formation according to the original version of Shenyuan Zhenjun."

"That's all, let's gather all the experience beads on the magic circle on the wall first."

Putting away the golden sword, Cao Rui picked up the metal plate and began to carve the magic circle.

The magic arrays on the wall were all magnified and engraved on the wall. After Cao Rui's spiritual consciousness was locked, he began to inscribe on the metal plate according to the gourd pattern.

Unlike when he was inscribing behind Wu Qingxuan, Cao Rui failed three times and spent three hours before successfully gathering the experience beads of the first magic circle.

In this way, it took five days for Cao Rui to condense all the experience beads from the sixteen first-order magic circles on the wall.

After condensing the experience beads, Cao Rui can engrave them next time and rely on the memory in his mind to increase the experience value of the experience beads without having to stay in the inheritance house.

Cao Rui also tried to condense the experience beads of the second-level magic circle.

In the end, it ended in failure.

Although his spiritual consciousness is equivalent to the third level of the foundation building stage, the requirements for the second level magic circle are only in the late stage of the foundation building stage before preliminary inscription can be carried out.

When Cao Ruizi tried it, he couldn't see clearly the second-level magic circle runes because of insufficient spiritual consciousness. If he forced them to inscribe them, his head would hurt.

Cao Rui just gave up on his own initiative.

Coming out of the inheritance house, Cao Rui found Wu Qingxuan and explained his idea of ​​the Lingyin Jade Pendant.

After hearing this, Wu Qingxuan frowned slightly, not to refute Cao Rui's whims, but to seriously think about the feasibility of Cao Rui's plan.

"The communication array of our Spirit Beast Sect has been expanded to the entire southwestern Yunzhou through the powerful radiation of the sect's fourth-level formation."

"The main material of the communication array, the spiritual pattern black crystal is also worth a lot of money."

"According to you, the main material of those signal towers should be spiritual pattern black crystal, plus the inscribed first-order magic circle, the signal tower must be maintained, right?"

"It works, but it requires a lot of effort and energy." Wu Qingxuan said.

Cao Rui raised his hand and said, "I would also like to ask Chief Wu to help me. After the project is completed, I am willing to give you 30% of the income from the Spiritual Sound Jade Pendant."

After hearing this, Chief Wu shook his head: "Thirty percent is too much. If you really want to give it, give it half a percent. 10% is almost enough."

"In the southwest of Yunzhou, there are about ten thousand monks from the inner and outer sects of the three major sects."

"The number of casual cultivators is not 300,000, but 200,000."

"If these casual cultivators had a Spiritual Sound Jade Pendant in hand, the benefits would be truly unimaginable."

"This is just the southwest of Yunzhou. The total number of monks in Yunzhou is over a million. If you hold a Spiritual Sound Jade Pendant, tsk tsk..."

Cao Rui couldn't help but chuckle slightly as he listened to Wu Qingxuan imagining the future for himself.

However, Wu Qingxuan's thinking was still too simple, and he only considered the value of the jade pendant.

He had no imagination to support him. When he got his hands on a product of his own, he would make a slight change in the product and it would have a huge impact.

Wu Qingxuan was persuaded by himself: "Cao Rui, your idea is very good."

"But the premise of everything is that we have to control costs."

"Technical and cost issues are the main problems that need to be solved at present." Wu Qingxuan said sharply.

Cao Rui nodded: "I want you, Mr. Wu, to help me with the preliminary development of the signal tower weapon. I am responsible for this little thing called the Spiritual Sound Jade Pendant."

Considering the expensive material of Lingwen Xuanjing, the Lingyin Jade Pendant cannot be very large.

But in Cao Rui's idea, at least two 0-level magic arrays need to be engraved on this small Lingyin Jade Pendant.

One is naturally [sound transmission].

The other is naturally [image transmission].

Combining the two, the Lingyin Jade Pendant can achieve video calls.

Imagine activating the Lingyin Jade Pendant to contact the person you want to contact.

After the other party is connected, the Lingyin Jade Pendant will directly project aura, condense the other party's real projection in front of you to talk to you.

It's like being there in person, or like the projection of the golden monk transmitting sound.

I believe that as long as this scene of using the Lingyin Jade Pendant spreads, those who witness it will be willing to spend spirit stones to purchase this jade pendant.

The only difficulty is that in order to restrain two 0-level magic arrays on such a small Lingyin Jade Pendant, it is necessary to practice the engraving of the 0-level magic array to an extremely high level.

Cao Rui felt that he, who only had the experience beads, could achieve this step in a short time.

First, he solved the Lingyin jade pendant and the 0-level magic array on it. After that, Cao Rui needed to continue to improve the realm of the 1-level magic array on the signal tower, so that he could upgrade the signal tower and increase the radiation range, thereby reducing costs.

Cao Rui just needed to wait for the sect's 500 portions of Bailu spiritual medicine materials in July.

So this time he concentrated on retreating in the sect, focusing on improving the magic array every day, and occasionally guiding the two deacons and disciples in the refining academy, and explaining to them the refining techniques of the fire lotus.

A month later, Zhang Mo successfully advanced to the foundation-building stage at Qinglingfang, and Cao Rui felt more at ease staying in the sect.
