After coming to the eighth layer of the Earthquake Tower, Lei Xiaotian sat cross-legged again, while commanding the Earthquake Tower, in the eighth layer of space, practicing the mysteries of the law of thunderstorms, and at the same time, Lei Xiaotian took out a Chaos Strange Fruit and said it down! The energy that was full of energy in an instant rose from Lei Xiaotian's lower abdomen and flowed all over Lei Xiaotian's body, Lei Xiaotian could feel that under the action of the energy of this chaotic strange fruit, his body strength was constantly improving, and at the same time, the divine power became more condensed than before, the soul space became clearer, and the soul origin was also enhanced!

At this time, the Earthquake Tower also gathered the thunder energy, simulating the various attacks and defenses of the Thunderstorm Law Mystery, under the effect of the Chaos Alien Fruit, as soon as the deduction began, Lei Xiaotian fell into a state of soul silence, and directly fell silent in the comprehension of the Law Mystery!

Gradually, Lei Xiaotian forgot everything around him, and closed his eyes for a while, a month passed, and Lei Xiaotian's body began to flash this thunder, purple thunder, constantly flashing on Lei Xiaotian's body, but Lei Xiaotian didn't know it!

A year has passed, and the thunder light on Lei Xiaotian's body has become more and more, and even intertwined, and it has begun to collide constantly, and each collision will emit bursting energy, but these Lei Xiaotian still can't feel it!

Ten years have passed, Lei Xiaotian's entire body, almost turned into a purple ball of light composed of thunder and lightning, but above this purple ball of light, there is a continuous sound of thunderbolts, and at this time, the Sky Quake Tower has stopped demonstrating, in the entire space, only around Lei Xiaotian's body, is still constantly flashing the light of this thunder and lightning, take a closer look, it turns out that around Lei Xiaotian's body, there are thunder and lightning, these thunderbolts are constantly colliding with each other, constantly exploding, gathering together, so it looks like Lei Xiaotian's body, has become a huge thunderbolt ball！

In this way, Lei Xiaotian himself was unaware, still closed his eyes, and continued to deduce, and it lasted for five years, from the eighth layer of space to the Earthquake Tower, Lei Xiaotian has experienced seventeen years, and one day, the thunder and lightning around Lei Xiaotian began to slowly merge into Lei Xiaotian's body, and finally revealed Lei Xiaotian's true body!

When all those thunderbolts disappeared, Lei Xiaotian also opened his eyes! After opening his eyes, Lei Xiaotian stood up directly, waved his hand, and with a turn of divine power around his body, a thunderbolt flashed, shooting out rapidly towards the front, and there was a loud cracking sound in the air, which caused the thunder and lightning to explode directly in the air! This trick that Lei Xiaotian used was the mysteries of the thunderstorm law that the Earthquake Tower had been practicing just now!

After the demonstration, Lei Xiaotian smiled slightly, and said: "This is the Thunderstorm Law Mystery in the Thunder Law Mystery, not bad, not bad! It's really a good idea to plant flowers and flowers without intentionally planting willows and willows! It's a pity, I am already a high-level god, and after comprehending the Thunder Law Mystery, although my strength has improved, the improvement is not obvious, it is just one more means!" After finishing speaking, Lei Xiaotian flashed, walked out of the Earthquake Tower, and came to the outside of the Earthquake Tower!

After leaving the Sky Quake Tower, Lei Xiaotian first took a look at the cave he had made, and after finding that there was no abnormality, he also walked out of the cave, looked outside, and after making sure that everything was normal, Lei Xiaotian returned to the cave again and entered the Sky Shaking Tower to continue his retreat!

After entering the Megatron Tower again, Thunder Roar still came to the ninth floor of the Megatron Tower, and continued to communicate with the Megatron Tower to simulate the integration of the laws and mysteries of various departments, and continued to deduce and watch over and over again!

Now, the mysteries of the seven laws that Lei Xiaotian has comprehended, there are already two systems of law mysteries, and he has comprehended all the realms of the nine great achievements, and only the mysteries of the laws of the five systems of light, space, metal, wood, and wind are left, and he has only comprehended the eighth, and there is still one that has not been comprehended! That is to say, now Lei Xiaotian has reached the high level of the upper god in terms of fire and thunder, and the mysteries of the laws of the five systems of light, space, metal, wood, and wind are only the middle level of the upper god!

Maybe there is a certain connection between the mysteries of various laws, maybe it is the thunderous weather that has arrived, anyway, in the next period of time, Lei Xiaotian is constantly watching and deducing, when the mysteries of various laws are fused, in the end, it is always impossible to make these laws and mysteries that are not fused completely integrated, but there will always be a period of study for a period of time, and you will suddenly comprehend a kind of mysteries of laws that have not yet been comprehended in the five systems of light, space, metal, wood, and wind!

Just like the last time he comprehended the mysteries of the laws of thunderstorms, so, next, Lei Xiaotian continued to go back and forth between the eighth and ninth layers of the Earthquake Tower, and after more than four hundred years in a hurry, Lei Xiaotian finally comprehended the mysteries of the seven laws of the seven systems, the last of the mysteries of the laws of heaven and earth in each department, all of them completely comprehended the realm of Dacheng, and since then Lei Xiaotian has finally become a high-level powerhouse of the seven systems!

The seven systems of law mysteries, the gain of the human body is different, so the seven systems of the law mysteries are all fully understood, which also makes Lei Xiaotian's strength increase a lot, of course, for more than 400 years, Lei Xiaotian has been talking about the focus of cultivation, in the fusion of the law mysteries, although it is said that there is no intention to plant flowers and flowers, but it is not without gains, over the years, out of the unintentional willows and willows, in addition to the last law of the seven systems, in addition to all the mysteries, Lei Xiaotian has also integrated some law mysteries, such as the last law of the fire system Lei Xiaotian comprehended the law of the law of the fire mysteries, in these more than 400 yearsOf course, it can be regarded as a beginner, but when it will be able to fully merge, Lei Xiaotian doesn't know!

Of course, in addition to the mysteries of the laws of the fire system, the mysteries of the six laws of thunder, light, space, metal, wood, and wind, and those that have not yet been fused, are also separated from several other mysteries that have been fused, and several of them have found opportunities for fusion!

Next, after Lei Xiaotian went out again to observe the surrounding environment, he entered the Heaven-Shaking Tower again and began to specifically deduce the mysteries of the laws of heaven and earth of various systems that had already found an opportunity to fuse!

Of course, the focus of Thunder Roar is still on the fusion of the fire rhythm law mysteries of the fire system, the fire elemental law mysteries, the fire rhythm law mysteries and the explosion law mysteries!

In this way, decades passed again, and Lei Xiaotian finally fused several laws and mysteries that he had found the opportunity to fuse, all of them to the final node, and there was only one time left to be able to fully fuse, but Lei Xiaotian found that even if you continue to retreat, there will be no progress, and a rough estimate is that he has been in retreat here for more than 500 years, so Lei Xiaotian decided to go out of the customs and go to the outside world for a period of time, because Lei Xiaotian knows that sometimes blindly retreating is ineffectiveWhat's more, he hasn't been out for more than 500 years, and Lei Xiaotian also wants to see the situation in the outside world!
