After selling some things in the city, Lei Xiaotian walked directly south out of the city. After coming out of the city, Lei Xiaotian used his divine power to build a small cave in the mountain on a small mountain, and sealed the entrance of the cave with divine power, and also arranged a lot of large arrays, and lived in it!

You must know that on the sixth floor of the Sky Shaking Tower, there are many formations, and it is not difficult for Lei Xiaotian to hide his cave! After living in the cave, Lei Xiaotian entered the Sky Shaking Tower again!

This time, Lei Xiaotian directly entered the eighth layer of the Megatron Shaking Tower, and began to communicate with the Megatron Megatron Tower with his mind, constantly letting the Megatron Megatron Pagoda simulate the mysteries of the laws of heaven and earth that he had not yet comprehended in various departments!

A year has passed, Lei Xiaotian is still watching these simulation drills of the mysteries of the laws of heaven and earth, two years have passed, Lei Xiaotian still has not come out, and in the cave, the Earthquake Tower has changed into the size of a speck of dust and is hidden in the cave, so Lei Xiaotian is not afraid of someone disturbing him!

Five years have passed, and on this day, Lei Xiaotian is watching the simulation drill of the last law of heaven and earth in this fire system, the mystery of the law of fire and the law of fire, you know, the various laws and mysteries simulated by the Sky Quake Tower are very real, so with the Sky Shaking Tower in hand, it is like having a cheat to comprehend the mystery of the law of heaven and earth.

Maybe it's because the hard work pays off, maybe it's Lei Xiaotian's talent, or maybe it's because the observation of the past five years has taken effect, and finally after the Sky Shaking Tower once again simulated the mystery of the law of fire rhythm, Lei Xiaotian suddenly had a trace of inspiration in his heart!

As a result, Thunder Screaming Heaven communicated with the Earthquake Tower, and began to simulate the mystery of the law of fire alone, and gradually Thunder Roaring Heaven fell into it, forgetting everything around him, as if he was silent in the world of fire!

Then, Lei Xiaotian closed his eyes and began to deduce the mystery of the law of fire rhythm, a year has passed, Lei Xiaotian has not moved, two years have passed, Lei Xiaotian still has not moved, ten years have passed, Lei Xiaotian's body began to burst into flames, and the clothes on his body were burned, but Lei Xiaotian still did not move!

Ten years have passed, and the flames on Lei Xiaotian's body began to flicker regularly, wave after wave, and began to flicker on Lei Xiaotian's body, and just like that, ten years later, Lei Xiaotian has completely become a fire man! All around are constantly flickering flames! And this flame is still flashing and spreading around!

A hundred years have passed, and the entire eighth layer of the Sky Shaking Tower has completely turned into a world of flames, and suddenly, these flames began to be recycled, and the speed of recovery is much faster than the spread! In this way, another ten years have passed, and all these flames have converged into Lei Xiaotian's body, and at this time, there is no trace of any flames on Lei Xiaotian's body! However, Lei Xiaotian still didn't move, nor did he open his eyes, as if he was still deposited in cultivation, and he was still deducing, comprehending the last law of the fire system, the mystery of the mysteries, the rhythm of fire!

Soon, the aura on Lei Xiaotian's body began to grow, and at the same time, the energy in the Sky Shaking Tower began to gather towards the Thunder Sky Tower, not only the energy of the eighth layer of the Sky Shaking Tower, but even the energy in the energy space on the seventh layer of the Sky Shaking Tower began to surge towards the eighth layer!

And Lei Xiaotian's body is like a water-absorbing sponge, constantly absorbing this infinite energy around, as the energy is continuously absorbed by Lei Xiaotian, Lei Xiaotian's breath is getting stronger and stronger, and with the enhancement of Lei Xiaotian's strength, the speed of absorbing energy is getting faster and faster!

In this way, Lei Xiaotian continued to absorb energy, for a whole year, the energy around Lei Xiaotian was still so much, fortunately, Lei Xiaotian was in the Earthquake Tower, otherwise in a year, such a rapid gathering of energy, it is estimated that the mountain range where Lei Xiaotian is located, due to the convergence of energy, will definitely make others feel that this is a treasure born!

Half a year later, Lei Xiaotian's breath no longer changed, and then Lei Xiaotian's body slowly slowed down the speed of absorbing energy, and then, a year later, Lei Xiaotian's body no longer absorbed the energy of heaven and earth, and then the energy originally gathered around it also began to slowly fade, and soon became the original appearance!

Just a year after Lei Xiaotian's body no longer absorbed energy, a red light suddenly flashed in the center of Lei Xiaotian's eyebrows, and after this red light flashed, Lei Xiaotian's soul origin also began to grow, and then it lasted for a year!

When he sneered that his soul origin was no longer growing, Lei Xiaotian suddenly opened his eyes, at this time, if someone was here, they would find that Lei Xiaotian at this time was no longer a high-level god, but a high-level powerhouse!

Lei Xiaotian has now fully comprehended all the Nine Heaven and Earth Law Mysteries of the fire system, and Lei Xiaotian has also fused the eight fire system of the Heaven and Earth Law Mysteries, according to the division of the strength of the God Realm, at this time Lei Xiaotian has completely become an eight-rank war god!

You must know that in the god realm, the high-level powerhouse of the upper god who generally fuses the eight kinds of heaven and earth law mysteries is the eight-rank god of war, and the person who integrates all the nine kinds of heaven and earth law mysteries is the high-level god of the Great Perfection, that is, the legendary nine-rank invincible god of war! That is, the strongest person in the god realm under the main god. So this retreat, although Lei Xiaotian has consumed more than a hundred years, it is really worth it, because Lei Xiaotian has finally completed the transformation and turned into an eight-rank god of war!

In the God Realm, the main gods generally do not show their faces, and the number of the Nine Rank War Gods is very rare, and most of them are enlightened, and they don't care about the idle affairs of the God Realm at all, so the Eight Rank War Gods are already the ones who really stand at the top of the pyramid in the God Realm!

After opening his eyes, Lei Xiaotian stood up, opened his mouth and laughed, he has been in the God Realm for so long, Lei Xiaotian has always felt that his strength is not enough, and he has done a lot of things, and he is tied to his hands, although Lei Xiaotian's strength is still far from the peak, but he can already have a place in the God Realm, so Lei Xiaotian laughed very happily!

After laughing, Lei Xiaotian's mind moved, and he directly flashed out of the Earthquake Tower, and put away the Heaven Shaking Tower! Then, Lei Xiaotian used the Heaven Shaking Tower to receive all the large arrays he had arranged into the Sky Shaking Tower, and then walked out of the stone cave of retreat!
