Lei Xiaotian closed his eyes and started refining the elixir, he didn't move for three months, but Lei Xiaotian could feel that his understanding of the laws of heaven and earth was getting easier and easier!

Three months later, the medicinal power of the elixir had all been refined by Lei Xiaotian, and then Lei Xiaotian stood up directly and began to comprehend the mysteries of the laws of heaven and earth, Lei Xiaotian had cultivated a total of seven mysteries of the laws of heaven and earth, and each of the mysteries of the laws of heaven and earth had comprehended the seventh, and now if Lei Xiaotian wants to pass this ninth level, he must fully comprehend the seventh of the mysteries of the laws of heaven and earth to the realm of Dacheng!

This time, Lei Xiaotian still started from the fire law mystery, the seventh fire law mysteries that Lei Xiaotian has now comprehended, that is, among the fire laws, the only law related to speed, the mystical fire technique, originally before entering the tower this time, Lei Xiaotian comprehended the seventh law of the fire law mysteries to the final stage, and only one foot left to reach the realm of Dacheng, so after taking this pill, due to the improvement of comprehension, it only took a few days for Lei Xiaotian to comprehend the fire technique to the realm of Dacheng！

Next, Lei Xiaotian began to make every effort to comprehend the mystery of the law of reflection in the mystery of the law of light, this mystery of the law of reflection is the law of the law of light, the law of defense is the law of the best defense, it can not only be defended, but also as long as it is used well, it can even be used to fight with strength, and this law mystery, Lei Xiaotian comprehended the closest to Dacheng, so it only took two days for Lei Xiaotian to comprehend it to the realm of Dacheng!

Immediately afterwards, Lei Xiaotian began to comprehend the wind law mystery in the wind system, this wind movement is the wind law that is originally good at speed, another law mystery that can increase speed, and this kind of heaven and earth law mystery comprehension is not very strong, although it is also to the most sufficient realm, but there is still some gap from the completion of the comprehension, at least worse than the fire law mystery demon! So it took Lei Xiaotian a month directly to fully comprehend it.

In fact, by this time, the Thunder Roaring Heaven Fire System, the Light Sect, and the Wind Sect had all comprehended the realm of the seventh Heaven and Earth Law Mysteries, and after comprehending all the Seventh Laws of the same system, Lei Xiaotian had already reached the level of the middle level of the upper gods.

Subsequently, Lei Xiaotian began to comprehend the mysteries of the laws of the thunder system separately, and after ten days of hard work, Lei Xiaotian finally comprehended the seventh law of the thunder system again to the realm of Dacheng!

Lei Xiaotian has comprehended the seventh of the four types of heaven and earth law mysteries of the fire system, wind system, light system, and thunder system, and the other three types of heaven and earth law mysteries, wood, gold, and space law mysteries, all of which have only comprehended the sixth type, and they have already been completed, that is to say, according to the clear explanation on the piece of paper left by the killing of the Holy Venerable Kells just now, Lei Xiaotian knew that he should have reached the requirements of this ninth level now, because all the heaven and earth law mysteries he had comprehended before had already comprehended the realm of Dacheng!

Sure enough, when Lei Xiaotian stopped cultivating and stood up, he raised his eyes to see that the light curtain blocking the door had completely disappeared, at this time Lei Xiaotian smiled slightly, Lei Xiaotian estimated that there were still a few years before the end of this pass, because Lei Xiaotian probably knew in his heart that when he was in the sixth level, although it was very difficult, it took less than a year, and although he felt that he had a relatively easy time in the seventh level, it took a lot of time to integrate those laws and mysteries, and during this period of time, Lei Xiaotian himself actually did not know how many years it was, and the eighth level of Lei Xiaotian did not take a long time, so Lei Xiaotian estimates that there should be a few years before the tower closes this time?

Therefore, Lei Xiaotian decided that he wanted to go to the tenth level quickly, because Lei Xiaotian wanted to pass all the levels directly this time and walk out of this god's cage directly, because Lei Xiaotian really didn't want to wait for another hundred years, because once he waited for another hundred years, maybe when he returned to the Holy Asian Plane, he would see a vicissitudes of life, which was the last thing Lei Xiaotian wanted to see, so after seeing the light curtain disappear, Lei Xiaotian almost didn't hesitate, and directly used the space ring to put away the stone table under him, and then, with his heart God commanding the Hundred Variety Divine Weapon in his hand, it turned into a sword。

Holding the sword in his hand, the sword transformed into a hundred magic weapons, Lei Xiaotian's body moved, and quickly walked to the open door, and walked up quickly with the staircase, the staircase was not long, and Lei Xiaotian knew that there would be no danger on the stairs, so he walked quickly, and after a while, Lei Xiaotian walked to the end of the stairs and saw the gate that entered the tenth level!

Then, Lei Xiaotian adjusted his physical state, and then, raised his feet and walked directly into the door that glowed with white light, this time as when he walked into the level the previous times, Lei Xiaotian still felt the transmission.

After the transmission ended, Lei Xiaotian found himself in a large hall again, and in this empty hall, there was an old man sitting upright, this old man revealed a strong coercion, although this old man, when Lei Xiaotian came in, did not move at all, but this coercion oppressed Lei Xiaotian felt a little breathless.

Observing this old man carefully, Lei Xiaotian found that this old man was the master he worshipped, the Killing Saint Venerable Kells, and the Killing Saint Venerable Kells sitting in front of him at this time did not seem to be an illusion, but an entity!

This Kells sat cross-legged on the ground as if he was an old student, his eyes slightly closed, the expression on his face was very calm, his long beard hung down on his chest, his snow-white hair was as smooth as his beard was draped over his shoulders, his hands were on his laps, and he held a small tower half a foot high, emitting bursts of white light.

Seeing this situation, Lei Xiaotian was slightly stunned, and then immediately knelt down on one knee in front of Kells, and said loudly: "Disciple Lei Xiaotian to meet the master, please give instructions from the master?" When he said this, Lei Xiaotian's expression was very respectful, although Lei Xiaotian was not a decent gentleman, but for his master, Lei Xiaotian still respected him very much, since he worshipped the master was his own master, Lei Xiaotian would not be sloppy at this point, so Lei Xiaotian saw this sitting Killing Saint Venerable Kells, and immediately saluted respectfully!
