I am eight years old again, and I will never serve as a cauldron for the empress again.

"With the help of thunder and lightning, my internal organs have been tempered. I didn't expect that I would be able to complete the first three small realms described in the Immortal Sutra so quickly!"

Zhuang Zhou talked to himself, his expression slightly agitated.

The "Immortality Sutra" is indeed a method specifically designed to temper the body.

After only completing the cultivation of the first three small realms, his physical strength actually doubled.

Originally, he had a special physique, and each realm was an extreme breakthrough, so his physical strength was terrifyingly strong. Just the physical strength of the peak Jindan realm alone reached the strength of thirty-six ancient elephants. Now it has doubled, and even without using any martial arts, he can have the strength of seventy-two ancient elephants. Even with pure physical strength, he can beat to death a strong man who has just entered the Earthly Evil Realm!

With such powerful physical strength, it is no wonder that Hei Wuji would doubt his own path to invincibility.

"The thunderstorm is vast, and this is just the beginning!" Zhuang Zhou looked up at the sky.

Among the layers of dark clouds, thick chains crisscrossed one after another. Each bolt of thunder was condensed from a vast thunder calamity. Thousands of thunders crisscrossed, sealing the sky.

"The current thunder tribulation has just entered the second stage. Ordinary masters of the Divine Ability Realm are already unable to withstand it. This is just a replay of the catastrophe at the end of the Middle Ages. If that catastrophe reappears, how many people in the Lingtian Realm can survive it now?"

Zhuang Zhou said with some worry.

The disaster that occurred at the end of the Middle Ages may reappear in the Lingtian Realm in the future.

Every era comes to an end.

The end of an era is often accompanied by the arrival of endless disasters.

"boom!"

A bolt of lightning with a diameter of tens of meters dropped from the sky with a deafening roar and hit the divine light barrier of Qi Sha City directly.

The solid barrier began to shake slightly, and the bright divine light began to dim.

This attack was equivalent to a full-strength attack from a peak Earthly Demon Realm expert.

The power is condensed and surging!

Even the barrier in the Seven Kill City began to shake slightly.

"Refill the Yuanshi, replenish the Yuanshi quickly!"

In the Seven Kills City, the people of the Black Demon Clan were in a hurry to replenish the Yuan Stones to the foundation of the formation.

The source of all the power of the Qisha City's formation comes from the Yuanshi piled up on each formation base.

Every time the thunder strikes, a large amount of energy in the Yuan Stone will be depleted.

"boom!"

Immediately afterwards, another huge bolt of lightning came crashing down.

This time the target is Zhuang Zhou.

Zhuang Zhou gritted his teeth and opened his arms to welcome the thunder.

He wanted to try the second stage of Thunder Essence to send his physical body to a higher level.

"Is this guy crazy? He was only granted the cultivation of the Tiangang Realm. The City of Sin God did not raise his body to the corresponding level. His body is still at the peak of the Jindan Realm. Even if he is tempered a thousand times, he can't withstand such a powerful thunder! If this thunder strikes, he will be reduced to ashes!"

On the wall of Qisha City, a soldier from the Dark Demon Clan opened his eyes wide and spoke in an incredible tone.

"Hey, if God wants to destroy someone, he must first make him crazy. If this guy can be killed by the thunderbolt, that would be perfect. As long as he dies, these heavenly tribulations will also dissipate. In this way, our Seven Killings City will not face the crisis of destruction."

Another patrol soldier from the Dark Demon Clan said with some gloating.

The silver light of thunder faded away, and they were all disappointed.

Although Zhuang Zhou's hair stood up and he looked a little disheveled, there were even silver arcs of electricity running on his skin.

But he was not seriously injured.

All the thunder was swallowed and absorbed by him to temper his internal organs and body.

Faintly, the roars of tigers and leopards could be heard coming from his body.

Tiger and leopard thunder sound!

This is a vision of a violent transformation of the physical body.

"The internal organs are the furnace to refine the thunder!"

According to the records in the "Immortality Sutra", Zhuang Zhou imagined his five internal organs as a huge furnace, which drew all the thunder into it, and then decomposed and tempered it, turning it into beneficial energy and integrating it into his limbs and bones.

This method has never been recorded in any book in Lingtian Realm.

It is unconventional and unique.

Zhuang Zhou originally thought that this method would not work, so he just gave it a try reluctantly.

Zhuang Zhou had even prepared the hand seal for the Secret of All Living Things.

As long as the thunder cannot be decomposed in the internal organs and flows everywhere, damaging the internal organs and meridians, he will seduce the endless vitality between heaven and earth to transform it into vitality, integrate it into his body, repair the damage, and continue on the old path of phoenix nirvana.

However, Zhuang Zhou had not expected that the method of using one's body as a furnace recorded in the "Immortality Sutra" would be so effective. He refined all the thunder power in the heavenly calamity with just one meditation.

The fourth level of physical training!

Zhuang Zhou's skin gradually turned into the color of brass, which is the level of copper skin recorded in the "Immortality Sutra".

Skin is like armor. If the skin can be tempered to a certain degree, it will be equivalent to a layer of close-fitting armor. It can not only enhance defense and protect against water and fire, but also unload some force and reduce damage to internal organs.

The shadows of eighty-one ancient statues appeared behind Zhuang Zhou, and they were about to break through the void.

The fourth level of physical training not only gave Zhuang Zhou a body of bronze skin, but also allowed his physical strength to continue to soar.

"No, we can't let Zhuang Zhou get stronger! We are consuming resources by fighting against the heavenly tribulation, but he treats it as a resource. I don't know what means this guy used to devour the thunder power in the heavenly tribulation. Under the heavenly tribulation, he is not only not injured, but is getting stronger!"

The commander defending the city of Qisha had a stern look on his face. He clenched his fists so tightly that his knuckles turned white.

The hatred for killing my brother is irreconcilable.

He thought that they could kill Zhuang Zhou as long as they could survive seven days.

However, what they did not expect was that Zhuang Zhou actually mobilized the heavenly tribulation.

With this kind of indiscriminate damage, I don’t know who will be killed.

Moreover, seeing that Zhuang Zhou was getting stronger and stronger under the heavenly calamity, if he continued at this rate, perhaps even without the blessing of the God of Sin, Zhuang Zhou would not be able to be killed by ordinary people.

He was thinking in his mind how he could take the initiative to kill Zhuang Zhou.

He looked towards the city, but unexpectedly his eyes met Zhuang Zhou's.

Zhuang Zhou grinned, revealing a cruel look.

The thunder in the sky suddenly became violent, and thick bolts of lightning seemed to be pouring down from the sky for free.

With Zhuang Zhou's physique, he only needed to withstand thirty to fifty of them.

The area and light of Qisha City are thousands or even tens of thousands times that of Zhuang Zhou's thunder!

"Oh no! I'm afraid we won't be able to hold on this time!"

In the city, a strong man in charge of dispatching resources looked pale, looked up at the sky, and said in extreme despair.

A bolt of heavenly thunder is equivalent to a full-strength attack from a powerful warrior in the Earthly Demon Realm.

These thousands and tens of thousands of heavenly thunders are equivalent to countless powerful men in the Earthly Demon Realm attacking together. Not to mention whether the divine light barrier in the Seven Killings City can withstand it, the Yuan Stones in the city that provide energy for the formation will probably be consumed in a short time.

as predicted.

Zhuang Zhou used his body as a furnace to refine thunder. His body continued to strengthen and transform, and he became braver as the battles went on.

In the Seven Kills City, thunder continued to strike, causing the divine light barrier to sway constantly and fine cracks to appear. It really showed signs of being shaky and could collapse at any time.

"This damn Zhuang Zhou, does he really want to drag the entire Seven Killings City to be buried with him?"

Hei Wuji threw away the chess piece in his hand and overturned the chessboard. His face was as black as ink.

This time he really couldn't sit still.
