The area of the thunder pool is not small, at least it is equivalent to a football field, and it is obviously formed by an extremely powerful prohibition, even if there are so many thunderbolts accumulated in the thunder pool, there is not the slightest energy leakage.

Even after Lin Fei became a strong man in the Yuan Infant Stage in his previous life, he didn't know much about the Lei Chi ban, let alone its origin, he only knew that such a ban had existed since the establishment of Canghai Academy.

The existence of the thunder pool is not only to collect thunder and lightning energy, but also to be able to control these thunder and lightning energy, so as to help the cultivators who enter the thunder pool to quench their bodies, which is conducive to adapting to the environmental changes after entering the wind and thunder gate.

There is no risk in the Lei Chi quenching body, but the process is not very pleasant, and it can even be said to be extremely painful. However, if you can't even bear this pain, you won't be qualified to enter the Wind and Thunder Gate, and entering is just a waste of resources!

At this time, in front of Lei Chi, there was an old man sitting cross-legged, looking very old with silver hair and silver beard, and even a little thin and withered, but he sat there cross-legged, but he had a kind of world-shattering spirit, obviously a rare strong man.

Lin Fei recognized this old man, when he entered the Wind Thunder Gate to cultivate in the previous life, he had dealt with this old man a lot, but at some times, he had to pretend to be the first time he met, and he bowed to the old man very respectfully, and said: "Hello teacher, student Lin Fei, now apply to enter the Wind Thunder Gate to cultivate, and ask the teacher for guidance!"

The old man's long white eyebrows covered his eyes, I saw him blow slightly, blowing his white eyebrows upward, and after glancing at Lin Fei, he asked in a hoarse voice: "You are Lin Fei?" Sure enough, there is something special, you actually want to enter the Wind Thunder Gate to cultivate so early? You can call me Mr. Yin, if you want to enter the Wind Thunder Gate in the future, just come to me directly, but you must pay enough credits. By the way, how many days are you going to practice this time?"

This Mr. Yin doesn't seem to be good-looking, but Lin Fei knows that he is faintly the number one master of Canghai Academy, an old professor who has retired from Canghai Academy, and now he is just volunteering to help guard the Wind and Thunder Gate.

This Mr. Yin is a peak powerhouse of Yuanying, and he once tried to impact the realm of transforming gods in the past, but unfortunately he failed to succeed when he crossed the thunder tribulation, but even so, he can be called a half-step transformation god, and he belongs to the top figures in the entire Kunlun realm second only to a few transformation god old monsters.

Mr. Silver has not much Shouyuan left, and he is also in charge of Lei Chi to give full play to his residual heat, with him guarding here, coupled with the prohibitions near Lei Chi, even if there is really a god old monster invading here, it is not Mr. Yin's opponent, and the Wind Thunder Gate is naturally as stable as Mount Tai!

When Mr. Yin broke through the "Nine Gates to the Heavens" in the past, he unfortunately stopped at the eighth layer gate, which was also the fundamental reason why he failed to hit the God Transformation Realm.

As if to make up for his regrets, Mr. Yin is very concerned about the junior students who come to Fengleimen to cultivate, and often takes the initiative to give some guidance, and Lin Fei in the previous life can be regarded as having received his favor, so Lin Fei respects Mr. Yin very much, and said respectfully in front of him: "The student intends to use all the credits to exchange for cultivation time, and I also ask Mr. Yin to give convenience." ”

Mr. Yin's long eyebrows moved again, and he asked in a slightly surprised tone: "All the credits are used to redeem? Well, you should enjoy the preferential condition that you only need to pay one-fifth of the credits, right? So you plan to cultivate for a month in one go? Well, such courage is indeed commendable! In this way, you first quench your body in the Thunder Pool, and then enter the Wind Thunder Gate to cultivate, if you want to quit halfway, the old man has a way to lure you out, and the credits that have not been consumed will be returned to you." ”

Lin Fei hurriedly thanked: "This is the best, thank you Mr. Yin for your care!"

Mr. Yin nodded, and did not talk to Lin Fei more, but pointed towards Lei Chi and motioned for Lin Fei to go in by himself. So Lin Fei was not polite, and slowly stepped into the thunder pool.

Just when Lin Fei stepped into the thunder pool, as if he had turned into a conductor to attract thunder and lightning, all the thunder and lightning energy accumulated in the thunder pool surged towards Lin Fei, instantly enveloping Lin Fei in a cloud of thunder and lightning sparks.

If the thunder and lightning energy had not been restricted by the prohibition, and the violent attribute in it had been extracted, if so many thunder and lightning powers were really to be fully slashed, most of the time it would have split Lin Fei's skin in an instant. As for Lin Fei now, he felt that his whole body was itchy and itchy, like countless ants crawling on his body, and that feeling was really uncomfortable.

Moreover, this itchy feeling seems to be able to penetrate into the bones, starting from the skin and flesh, and constantly penetrating into the body, and its strange feeling is really difficult to describe in words.

Lin Fei had experienced the thunder pool quenching body in his previous life, but he didn't feel as uncomfortable as he did now, probably because his body was transformed by nanoparticles, which could hold more energy, and if he wanted to temper such a body, he would naturally need more lightning energy, and the suffering that Lin Fei had to endure was also very different from the previous life.

After that tingling sensation spread all over the body, the thunder and lightning energy began to stimulate every cell in Lin Fei's body, and the nanoparticles also played a role at this time, secretly absorbing a trace of thunder and lightning energy hidden in the internal space of the cell, just like Lin Fei's body played the role of a thunder pool.

Even though Lin Fei had the experience of the previous life, he was a little unexpectedly unaware of this special change, and the expression on his face would inevitably change somewhat, as if he couldn't bear the pain of Lei Chi's quenching body. However, Lin Fei knew that such an opportunity was rare, and after his body adapted to the thunder and lightning energy, the next time he used the thunder pool to quench his body, he might not have the opportunity to absorb the thunder and lightning energy into his body.

So Lin Fei calmed down and silently endured the pain of the thunder pool quenching his body, and at the same time tried to introduce more thunder and lightning energy into his body, hiding it deep in every cell.

At present, Lin Fei can't judge what the benefits of hiding thunder and lightning energy in his body are for the time being, but he believes that after his body adapts to the thunder and lightning energy, whether it is to break through the "Nine Gates to the Sky" or to welcome the thunder tribulation in the future, it will be of great benefit.

Time passed slowly like this, Lin Fei was always receiving the Lei Chi quenching, and it seemed that there was no sign of ending.

Since Lin Fei stepped into the thunder pool, Mr. Yin has been paying attention to Lin Fei's changes, although Lin Fei was wrapped in countless lightning sparks, he couldn't stop Mr. Yin's sharp gaze, and he could even see the changes in the expression on Lin Fei's face!
