Cheng Sifan was lying on the bed and tossing and turning. Although Lu Cheng was just an acquired warrior, he felt that he could not see through it. Lu Cheng could easily kill Wu Qingtian, but he was not injured at all. This aroused his strong curiosity. If he could not solve this mystery, he would probably not be able to sleep at night.

There is also the failure of the spirit stone on Shitianyun Scorpion Peak, which is probably caused by Lu Cheng. Any of these two things are unpredictable.

However, although Lu Cheng was young, he was not frivolous. Even though he drank a lot of alcohol, his mouth was still very tight. Whether it was killing Wu Qingtian or the matter on Shi Tian Yun Scorpion Peak, he didn't ask at all. In the evening, Cheng Sifan originally wanted to meet someone else, but after thinking about it, he still focused all his thoughts on Lu Cheng.

What made Cheng Sifan a little depressed was that Lu Cheng seemed not very enthusiastic about him. Although Cheng Sifan was a warrior in the late stage of the second-level innate level, no matter who met him in the Ling'an Emirates, he would give him enough face and flatter him. Even a super-large family like the Wu family and the Fang family would give him face no matter what.

For example, if he came to Shitianyun Poker Peak, if he said hello in advance, no matter whether he wanted 300 or 500 spirit stones, Wu Wenkang would give it to both hands. But Cheng Sifan didn't want to owe this favor, so he thought of entering the tunnel to search for it at night. But unexpectedly, Wu Wenkang discovered it. Moreover, Wu Wenkang did not give face at all, and would have to kill him if he took action. If it weren't for Lu Cheng, he would have to explain it to the tunnel.

Although Cheng Sifan couldn't sleep, he found that Lu Cheng didn't seem to really fall asleep. As a warrior, he should practice at any time. But Lu Cheng seemed to be just pretending to sleep.

"Lu Cheng, if you want to practice the mind method, I can protect you." Although Cheng Sifan was separated from Lu Cheng, in the eyes of the innate warriors, this wall seemed to be non-existent. His straight line distance from Lu Cheng was no more than five zhang. In addition to not being able to see Lu Cheng, his perception was as clear as Lu Cheng's every move. Especially Lu Cheng's breathing, he could accurately judge Lu Cheng's behavior and state from Lu Cheng's breathing.

"Thank you." Lu Cheng's induction told him that Cheng Sifan was talking, but what surprised him was that Cheng Sifan's voice seemed to be right in his ears. This surprised him very much. He knew that Cheng Sifan was next door, but he still couldn't help but turn around to see if Cheng Sifan was by his side.

"No need to read, this is the method of voice transmission." Cheng Sifan said with a chuckling. The so-called method of voice transmission is actually to gather the sound into a thread and send it to other people's ears. In addition to Lu Cheng, even the person next to Lu Cheng could not hear what he said.

"Method of voice transmission?" Lu Cheng was even more curious.

"If you want to learn, I can teach you." Cheng Sifan said with a smile. There are not many things that can interest Lu Cheng. Although the sound transmission method is an innate martial art, it is not profound. But acquired martial artists cannot learn it because they need to release their true energy. However, Lu Cheng's internal strength can be released, so it is naturally no problem.

"Thank you." Lu Cheng said. He didn't want to owe Cheng Sifan the favor. He had already started learning when Cheng Sifan was using the sound transmission method. Since he could learn it himself, why bother Cheng Sifan again?

"Actually, it's very simple. Your internal strength can be released and you can learn it once. Now I will tell you the mental method, and you can practice it while learning." Cheng Sifan ignored Lu Cheng and directly spoke out the mental method of the voice transmission method.

Lu Cheng really knew it once he learned it. As soon as Cheng Sifan opened his mouth, he noticed Cheng Sifan's mental method. Now he corresponded to the mental method that Cheng Sifan said. The two corresponded to, and Lu Cheng quickly began to enter the door. Within half an hour, Lu Cheng began to try to talk to Cheng Sifan.

"Thank you." Lu Cheng was a little uncomfortable with the first time using the voice transmission method, because he had just learned this mental method. After all, he used the voice transmission method for the first time, and the sound was intermittent. But soon, Lu Cheng added: "Although the voice transmission method is simple, it is very practical."

The following sentence was much more fluent and there was no sense of pause at all. Even Lu Cheng was very satisfied with his performance. As for Cheng Sifan, when he heard Lu Cheng say the word "thank you", he was so surprised that he couldn't believe his ears, as if he was blowing from the blue. After Lu Cheng said later, "Although the sound transmission method is simple, it is very practical", he completely lost his voice.

The method of voice transmission is indeed very simple and easy to learn, but it is not as simple as learning it in half an hour, right? I am not bad at talent, but it took me ten days to learn the method of voice transmission. I remember that after learning it, my master praised me for my high talent and good understanding. But now compared with Lu Chengyi, I am like an idiot. I learned the method of voice transmission in half an hour. If I hadn't heard it with my own ears, no one would believe it if I said it.

Now Cheng Sifan finally understood why Lu Cheng had such a high cultivation level at a young age. From the speed of his martial arts, he knew how terrifying his internal energy would be. Once Lu Cheng was promoted to the innate world, he would probably not take long to catch up and surpass himself.

Suddenly, he suddenly had an idea in his mind. However, this idea made him hesitate. And it was soon rejected by him. Lu Cheng's talent was the only one he met in his life. But after all, he only had one person, and it might not be a problem to build a small family.

But if he wants to gain a foothold in the Ling'an Emirates, or even in the Feigela continent, he may not be able to do it within 20 or 30 years. Can Lu Cheng live for another twenty or thirty years in the Feigela continent? I'm afraid that it would be a miracle that he wants to live for another twenty or three months.

"Lu Cheng, you are such a genius. It usually takes twenty days for ordinary innate warriors to learn this, and those with high talent can also take half a month. I used it for ten days and was praised by my master. It only took half an hour now. I really doubt whether you have learned it before." Cheng Sifan sighed.

"Ah, I would tell you about this matter tomorrow," Lu Cheng said embarrassedly. He would be disguised as to understand voice change, and learning voice transmission method does have a solid foundation. Many people learn the mental method quickly, but it is difficult to practice it.

"Lu Cheng, you have recently become a grudge with the Wu family, why not leave the Ling'an Emirates?" Cheng Sifan suddenly said that if Lu Cheng continues to stay at Shitianyun Scorpion Peak, or even in Ling'an Emirates, it will be very dangerous. But if you leave Ling'an Emirates, Lu Cheng may still have a glimmer of life.

"I have to stay here for a while." Lu Cheng said, and he understood Cheng Sifan's kindness, but if he could not break through the twelve level of internal strength, he would not have left Shi Tianyun Scorpion Peak.
