The best immortal emperor

Chapter 3631 Refining Mysterious Thunder Seal

On the other hand, Li Ming returned to Tianhaigou with the black bottle, and immersed himself in research all day, regardless of the changes in the outside world.

Apart from the smell, the black bottle seems to have no other special features. Anyway, after several days of groping, Li Ming didn't find anything unusual.

"Would it be different if this black bottle is used together with the Xuanlei Seal?" Li Ming said to himself.

After reading this, Li Ming turned his palm and took out the Xuanlei Seal, and began to study together.

When Xuan Lei Yin met the black bottle, he didn't have a special reaction, as if two unrelated things.

"Why don't you refine it first?" Li Ming said to himself.

Immediately, Li Ming released his divine sense, entered the Xuanlei seal, and opened the black bottle at the same time.

Li Ming was used to that stench, and now he smelled it again, and he wouldn't vomit anymore.

At the beginning of the refinement, it was exactly the same as before. As soon as the refinement started, illusions appeared.

Li Ming has long been used to it, and can resist the temptation of these illusions with his own perseverance, but with the deepening of refining, he can no longer rely on perseverance to resist.

"No, I feel like I'm going to fall into these illusions again." Li Ming said to himself, while preparing to get out of these illusions.

But at this moment, the stench of the black bottle suddenly came, and Li Ming's spirit froze for a while, and the phantom in front of him disappeared immediately.

"Huh? The phantom disappeared?" Li Ming's eyes suddenly lit up, and he said inwardly, "So that's how the stench from the black bottle is used!"

After understanding, Li Ming devoted himself to refining.

Now that the stench of the black bottle is refreshing, Li Ming is not worried about falling into hallucinations again.

Next, the refining process was relatively smooth.

With the deepening of refining, Li Ming also felt the horror of Xuanlei Seal more and more.

"If the power of the Xuanlei Seal is fully released, even the Venerable Heavenly One might not be able to hold it?" Li Ming said to himself.

After an unknown number of years, Li Ming finally succeeded in refining the Xuanlei Seal.

"Huh..." Li Ming let out a breath of foul air secretly, and then flew out of Tianhaigou.

Recalling the refining of the Xuanlei Seal, from the beginning of falling into an illusion and unable to extricate myself, to finding a way to refine it, until now it is completely refined, it took nearly a thousand years.

"Thousands of years?" Li Ming shook his head for a while, and said to himself: "Thousands of years are really a flick of a finger!"

One must know that it only took Li Ming a thousand years to cultivate to the Heavenly Exalted Realm, but it took him a thousand years to refine a Xuanlei Seal, which is really unimaginable.

"I don't know how long it will take to refine the Heavenly Thunder Seal?" Li Ming muttered to himself.

However, Li Ming is not in a hurry to refine it now, because he knows that if he cannot find the correct way to refine it, it will be futile.

"It's a pity that Patriarch Zulong doesn't remember the refinement of Tianlei Seal." Li Ming secretly felt sorry.

"Wait, the Sea Beast King said that there was a letter in the memory of Patriarch Zulong, and that letter recorded some things about the Heavenly Thunder Seal. Could there be a method of refining?" one light.

"Just where is that letter?"

This was a memory that the Sea Beast King hadn't looked up at the beginning, and it might be that there was a deviation when he captured the memory.

"Forget it, let's go back to Wulian City first, and see if the Three-headed Huojiao has collected any information about the Four Kuai Thunder Seal!" Li Ming said secretly.

Immediately, Li Ming flew towards Wulian City.

With Li Ming's current strength, it is only a matter of moving from Tianhaigou to Wulian City.

In a blink of an eye, Li Ming came to the gate of Wulian City, only to see that the notice to collect the four thunder seals was still posted on the gate of the city.

Entered the city and came to the city lord's mansion.

"Three-headed Huojiao, Sea Beast King, quickly come to see me!" Li Ming said via voice transmission.

Immediately, the three-headed fire flood dragon rushed over quickly.

"Master, are you back?" the three-headed fire dragon asked respectfully.

"En." Li Ming nodded, and then asked: "Have you collected any useful clues over the years?"

"Master, I did collect some, but my subordinates have no way of distinguishing the real from the fake, and just recorded them one by one." The three-headed fire flood dragon replied.

"Where is the brochure?" Li Ming asked.

"It's on the subordinate's body, and the subordinate will take it out now." The three-headed fire flood dragon said.

Immediately, the three-headed fire dragon took out the booklets recorded over the years, at least six or seven hundred.

"So many?" Li Ming couldn't help being surprised when he saw so many brochures.

Then, Li Ming released his divine sense and looked it up.

After a slight pause, Li Ming suddenly realized that the Sea Beast King hadn't come yet, so he couldn't help asking: "Three-headed Huojiao, the Sea Beast King?"

"Return to Master, the Sea Beast King is breaking through the Venerable Land recently, so he couldn't come here." The three-headed fire flood dragon replied.

"Oh?" Li Ming was stunned, and then asked: "He is going to break through the earthly statue? When did it happen?"

"It's been 30 years, but so far, there are no obvious signs of a breakthrough. I'm afraid it will take a long time." The three-headed fire dragon replied.

Hearing this, Li Ming nodded and said, "Let him retreat in peace, and don't disturb him."

"Understood, master." The three-headed fire flood dragon responded.

"En." Li Ming responded, and continued to look up these brochures.

At this time, I saw the three-headed Huojiao hesitated to speak, as if he had something to say.

"Just tell me what you want," Li Ming said.

"Master, Chen Feng'er from Bahuang City in the Northwest Territory seems to have lost his temper." The three-headed Huojiao said carefully.

"Huh?" Li Ming couldn't help but frown and asked, "When did it happen?"

"It has been more than 200 years, and now Chen Feng'er is imprisoned in the extreme north by the Northwest King, trying to use the cold air of the extreme north to suppress her demon nature." The three-headed fire dragon replied.

Hearing this, Li Ming's brows flickered slightly. Although he didn't have any special feelings for Chen Feng'er, he was considered a friend. In addition, the Northwest King also gave him a map of the Xuanlei Seal and a magical black bottle, so Li Ming Ming absolutely cannot stand by and watch.

After a pause, I saw Li Ming put away these booklets with a big wave of his hand, and then said, "I'll go to the extreme north."

After speaking, Li Ming's figure disappeared in place.

Teleport all the way, without any stop and delay.

Hundreds of years ago, Li Ming came to the extreme north, and now that he came again, he felt a little kind.

"I don't know where Chen Feng'er is being held?" Li Ming whispered to himself.

Now, Li Ming can only fly as far north as possible

In fact, Li Ming never thought that Chen Feng'er would go mad, because she doesn't seem to be the type who is eager for quick success.

However, the world is unpredictable, who knows?

Along the way, the climate is getting colder and the wind and snow are getting bigger and bigger. Looking around, the sky is full of snow, and there are ice and snow everywhere.

Half a month later, Li Ming had arrived at the extreme north, and going north would be the end of the world.

"Where will it be?" Li Ming frowned secretly.
