At present, the person who knows Lin Fei best in Canghai Academy is probably Mr. Yin, and when he saw Lin Fei appear in front of him again, he had already guessed Lin Fei's intention.

"You kid, are you planning to break through to a small realm this time? Well, although it hasn't been long since you have been promoted, with your accumulation, it shouldn't be a problem to break through again. Haha, it seems that even you kid is feeling pressure this time!"

Lin Fei looked very calm in front of Mr. Yin, and said calmly: "In order not to let you keep showing me a face, I can't do it this time if I don't work hard." There is a hidden dragon and a crouching tiger in the academy, and it is impossible to eat all over the world by relying on one move, and in the end, it is still necessary to rely on strength to speak!"

Mr. Silver touched his silver beard and said, "Looking at your kid's appearance, it seems that you are really confident in this breakthrough." Hmph, don't end up capsizing in the gutter!"

Lin Fei knew that Mr. Yin said this out of concern for himself, and also to remind himself not to be complacent, so he nodded and said: "Mr. Yin, your boss can rest assured, what level of cultivation holy land is this Wind Thunder Gate? Now that I have only broken through to the middle level of foundation building, will there be any problems? When the student comes out of the Wind Thunder Gate, I will definitely let you see a new me!"

Mr. Yin glanced at Lin Fei and snorted, "I hope you kid isn't blowing nonsense!"

Lin Fei respectfully saluted Mr. Yin, and then stepped into the Thunder Pool, and in a white lightning light, he once again entered the Wind Thunder Gate.

Lin Fei's goal of entering the Wind Thunder Gate this time was very clear, that is, to break through to the middle level of foundation building, so he went straight to the halfway point of the Wind Thunder Gate, and chose a cave with a good location to close up.

Since he was seeking a breakthrough in the Wind Thunder Gate, how could the movement that made it be small? Moreover, in the Wind Thunder Gate, Lin Fei didn't need to worry that his secret would be exposed, so he had already gone all out when he first started the retreat.

As Lin Fei let go of all his breath, it soon caused a crazy surge of spiritual energy around him, converging towards the cave where Lin Fei was retreating at a terrifying speed.

A moment later, above the cave where Lin Fei was retreating, a huge spiritual energy vortex was formed, like a bottomless pit, not only absorbing spiritual energy, but even attracting a series of lightning strikes.

However, the current height is only halfway up the mountain just past the Wind Thunder Gate, and the thunder and lightning energy caused here is not too powerful, compared to the spiritual energy that Lin Fei has absorbed, it is not enough to see at all, even if the momentum of the thunder and lightning is very amazing, but the effect is like light thunder and no light rain, and it does not affect Lin Fei.

In fact, don't look at Lin Fei's breakthrough to the middle level of foundation building, but the movement he is making now is even more terrifying than that of ordinary cultivators breaking through to the Jindan realm, and an ordinary thunder like this naturally doesn't have much impact.

Even Mr. Yin didn't have the ability to observe the specific situation in the Wind and Thunder Gate, but he could sense the changes in the spiritual energy in the Wind and Thunder Gate, and as the spiritual energy in Lin Fei's retreat gathered more and more, Mr. Yin's long silver eyebrows kept stirring.

Lin Fei, this kid, just broke through to the middle level of foundation building, and the movement that came out actually seemed to have broken through to the Jindan stage, it seems that there should be no problem with the success of the breakthrough, and what kind of performance will he have in the selection battle next? It is really worth looking forward to......

As for Lin Fei, who was in retreat at this time, he was already completely surrounded by rich spiritual energy, and if you observed Lin Fei with the naked eye, it could be said that he could not be seen at all, because the spiritual energy of each system had turned into a substantive-like brilliance, completely covering Lin Fei's entire body.

Cultivators in the foundation building period can cause spiritual energy resonance, but the movement that Lin Fei made is no longer as simple as resonance, but the spiritual energy of various systems is completely entangled together, as if forming a whole, and even the sound caused by spiritual energy resonance is all sealed in the spiritual energy light like substance.

Under the impact of such a rich psionic energy, every inch of Lin Fei's body was like being hit by a hammer with a force of ten thousand jun, and it had been tempering his body in such a special way.

Under such an impact, it was like the invisible shackles tied to Lin Fei's body were shattered one after another, starting from Lin Fei's epidermal skin, one by one cells directly exploded, and then quickly repaired, which was equivalent to gaining a new life, making the vitality of each cell more vigorous, and even the meson space in the cell was directly expanded at least doubled!

This change in the cells in Lin Fei's body seemed to have a chain reaction, spreading at an extremely fast speed, and soon all the cells in his body were transformed. Moreover, in the process of cell division and repair, more spiritual energy was devoured by the cells, and when Lin Fei's entire body was completely renewed, the strength he possessed was not the same as before.

In fact, in the process of Lin Fei's rebirth, he had successfully broken through to the middle level of foundation building, and easily improved his strength again.

Promoted from the initial level of foundation building to the middle level of foundation building, after all, it was only a breakthrough in a small realm, with the depth of Lin Fei's accumulation, coupled with the fact that he was in a holy place of cultivation like the Wind Thunder Gate, it really made this breakthrough a matter of course.

Lin Fei, who had just broken through to the middle level of foundation building, still needed a large amount of spiritual energy to fill the needs of his body, and this problem was not a problem at all in a cultivation holy place like the Wind Thunder Gate, seeing that the surging spiritual energy around him kept surging towards Lin Fei's body, there was no need to worry about the possibility of insufficient spiritual energy, and there was no need to even arrange the spiritual stones in advance in case of emergency.

Moreover, the spiritual energy absorbed by Lin Fei was not only the spiritual energy supplement needed after the realm breakthrough, at this time, every cell in his body, due to the space formed by the nanoparticles, was also improved, and naturally could accommodate more spiritual energy, so more water and fire spiritual energy was absorbed into the space inside the cell and stored.

If Lin Fei used his method of blending fire and water now, I believe that the power that erupted in an instant would have earth-shaking changes!

This time there is still a surplus of cultivation time in the Wind and Thunder Gate, Lin Fei does not need to worry at all, he can continue to accumulate spiritual energy in an orderly manner, completely stabilize the realm after he has just broken through, and take this opportunity to adjust his state, and when he breaks through, he will participate in the academy selection battle with a new attitude......
