Zeng Xiaoyu's expression moved, the dragon soul dwells underground, and there may be treasures inside.

So Zeng Xiaoyu's figure fell, and he immediately landed towards the deep hole.

At the mouth of a deep cave, there is thunder and lightning beating.

However, after Zeng Xiaoyu was integrated into the thunder spirit root, these thunderbolts were no longer able to threaten Zeng Xiaoyu, and Zeng Xiaoyu directly passed through the blockade of thunder and lightning and entered the deep hole.

The cave was deep, a mile in circumference, like a bottomless abyss, leading to the ground.

Zeng Xiaoyu descended all the way, and thunder and lightning exploded under the abyss from time to time in the middle.

However, these explosive thunderbolts immediately became docile when they came to Zeng Xiaoyu's side.

Zeng Xiaoyu descended for a while, and only then did he come to the bottom of the abyss.

Zeng Xiaoyu's divine sense swept and found a huge skeleton lying at the bottom of the abyss.

And before this skeleton, there was a human skeleton with its back against the abyss wall.

The cultivation of these two skeletons must have been extremely high during their lifetime, even if they had fallen for so many years, after years of thunder and lightning bombardment, they had not decayed.

On the contrary, the whole body is as black as jade, and there is thunder and lightning beating on it.

Zeng Xiaoyu guessed that the long skeleton should be the skeleton left behind after the death of the thunder dragon.

Although the flesh has decayed, the keel is intact, and the dragon's head can still be seen in the fierce majesty of the year.

Looking at the human bones again, the flesh at this time was also decayed, and the clothes on the body were long gone, only a black ring on his finger attracted Zeng Xiaoyu's attention.

Zeng Xiaoyu stretched out his hand, and the ring on the skeleton's finger immediately flew out and fell into Zeng Xiaoyu's hand.

Zeng Xiaoyu held the ring in his hand, and his divine sense swept into the ring, and he immediately frowned with joy.

Although there are only a few treasures in the storage ring, each one is extremely precious.

For example, several spiritual treasures in it have reached the level of high-grade spiritual treasures.

It can be seen that the owner of this skeleton must have an extremely high cultivation in front of him.

After all, who can come to the Thunder Realm is not a person who has real skills, his own cultivation and strength are extremely high.

In addition, there is the skeleton of a thunder dragon in the place where this person fell, as well as the contents of this person's storage ring, all kinds of signs prove that this person's cultivation is not bad.

Zeng Xiaoyu ignored the spirit treasure and pill in the storage ring for the time being, but with a movement of his mind, a somewhat mutilated silver page appeared in his hand.

The material of the page is very strange, light on one, but heavy as a mountain to start.

The top of the pages is densely engraved with many strange characters, crooked and twisted like tadpoles.

And on top of these characters, there is thunder beating from time to time!

Zeng Xiaoyu was a little shocked and took the page and looked at it carefully, but he looked at it for a while, but he still didn't understand what was recorded in the page.

Zeng Xiaoyu simply gave up the research, and instead asked the system in the sea: System, please help me scan to see what is recorded in this silver book.

System: The system is scanning, please wait...

Ding, the system scanned a page of the Lingque Silver Book, and what was recorded on it was a thunder cultivation exercise.

Lei Xiu belongs to the taboo of the nether realm, this exercise is ranked as a promotion, and it can be restored and perfected, please confirm whether it is upgraded and perfected?

"Confirm!"

Zeng Xiaoyu's face was ecstatic when he heard this, and someone sent a pillow when he fell asleep, where would he be unhappy?2k

Zeng Xiaoyu immediately ordered the system to help upgrade and improve this exercise.

The system is being upgraded and improved, please wait...

Ding, the system has completed the improvement of the exercises, please check the host...

When the voice of the system fell, countless pieces of information poured into Zeng Xiaoyu's mind.

Zeng Xiaoyu received the information from the system, and his face became extremely exciting.

After practice, you can replace the way of heaven and control the thunder, and those who are not afraid of thunder have the meaning of replacing the sky!

Therefore, when this practice is born, it is incomplete, and it is impossible to practice.

Without the help of the system, Zeng Xiaoyu would really not be able to perfect and restore the exercises.

Not to mention perfection and restoration, you can't even read the contents of the silver book.

The words engraved on this silver book are not words in the extraordinary or spiritual realm, but in the heavenly realm.

The average person simply can't understand it.

Zeng Xiaoyu was excited in his heart, he had just integrated a top-grade thunder attribute spirit root, which was just right for cultivating this Divine Thunder Dao.

And once practiced, he can control the thunder of heaven and earth, without fear of thunder, and can turn the thunder into his own use.

Absorb, refine, harness...

Controlling the heavenly thunder, like a heavenly punisher, such a thunder method, how can it not be exciting?

After digesting the content of the exercises a little, Zeng Xiaoyu only thought about it for a while, and then decided to cultivate this Shenxiao Thunder Dao here.

After all, the thunder realm is full of thunder, and the thunder power is very abundant, which is an excellent place to cultivate the Divine Thunder Dao.

After deciding down, Zeng Xiaoyu waved his hand and put away the keel and the remains of his predecessors on the ground.

Then he sat cross-legged on the ground and began to comprehend the contents of the Divine Thunder Dao.

When Zeng Xiaoyu had thoroughly digested the content of the exercises, he began to sit at the bottom of the abyss and cultivate.

Under the operation of the Shenxiao Thunder Dao, the surrounding thunder and lightning began to rush into the bottom of the abyss, and were absorbed and refined by Zeng Xiaoyu.

Zeng Xiaoyu has a thunder attribute spiritual root, and now he has a high-level thunder attribute exercise to help.

The thunder and lightning that were originally raging and raging came to Zeng Xiaoyu's side, and they immediately became docile, and they all drilled into Zeng Xiaoyu's body, and were absorbed and refined by Zeng Xiaoyu's operation exercises.

But even the thunder and lightning that have become docile are terrifying energy.

When the thunder and lightning first entered the body, the thunder and lightning were circulating in the body, and Zeng Xiaoyu could still feel the pain and tingling.

However, after the continuous tempering of thunder and lightning, Zeng Xiaoyu's body and muscles have become stronger and stronger, and he has surpassed the limits of human beings and reached an unbelievable level.

The enhancement of the physical body made the pain in Zeng Xiaoyu's body gradually disappear, and finally became numb, without a trace of pain.

The enhancement of the physical body made Zeng Xiaoyu absorb the thunder and lightning more quickly, and he was able to refine a large wave of thunder and lightning almost instantly.

The speed of absorption and refining accelerated, causing the thunder and lightning outside to pour in even more frantically, and finally at the exit of the abyss, a large-scale thunder vortex was formed.

The thunder whirlpool was covered with dark clouds, and thunder and lightning continued to explode inside, and the root-like thunder and lightning appeared like a giant dragon, and rushed towards the bottom of the abyss with teeth and claws.

However, when these thunderbolts came to the bottom of the abyss, they immediately turned into thick black energy, which poured into Zeng Xiaoyu's body and was absorbed and refined by Zeng Xiaoyu.

After absorbing and refining a large amount of thunder and lightning power, as more and more thunder and lightning were devoured, the aura on Zeng Xiaoyu's body became stronger and stronger.
