The Thunder Domain has a very special meaning to Zi Chen.

The first time he avoided the pursuit, he relied on the Thunder Domain. After that, the thunder and lightning in the thunder domain became his hole cards again and again, and he used these thunderbolts to resolve crises for him again and again.

Thunder Domain is a lucky place for Zi Chen.

Legend has it that the Thunder Domain evolved after the Thunder God Temple collapsed into a corner. Now that the Thunder God Temple has reappeared in the world, Zi Chen said that he would go to the Thunder Domain to find out what the corner of the Thunder God Temple was.

The thunder and lightning in the thunder domain were still roaring, and Zi Chen's perfect spiritual thoughts were in the outside world, and nothing abnormal could be detected at all. Now the forbidden space realm outside the thunderfield has no effect on him, and his body flashes and he enters the thunderfield.

The figure flashed again, he had already reached the ninth layer of the Thunder Domain, and he didn't need the thunder mark at the center of his eyebrows, Zi Chen could step into the ninth layer of the Thunder Domain with his own strength.

In the nine-layer thunder domain, the lightning energy is still divided into levels, and each level is stronger than the first. There are thunder crystals floating above the nine-layer thunder domain, the big ones are the size of fists, and the small ones are the size of walnuts, these thunder crystals are no longer attractive to Zi Chen, but they are also rare top-level refining materials.

With the extension of spiritual thoughts, the surrounding thunder crystals converged towards Zi Chen.

After receiving these thunder crystals, the golden mark at the center of Zi Chen's eyebrows reappeared, and he felt the pressure from this layer, and he didn't dare to hold it up any longer. Sure enough, as soon as the eyebrow mark came out, Zi Chen felt that the pressure was greatly reduced, but there was still a compelling aura.

Obviously, in the depths of this thunderfield, there are still thunderbolts that can threaten Zi Chen.

Zi Chen began to go deeper, and soon arrived at the place where he had obtained the Thunder Soul Crystal, and then stepped forward. This is the second level in this layer of thunder domain, and the power of thunder and lightning is one level higher.

Thunder and lightning roared, but they walked around Zi Chen.

After Zi Chen stepped into the second level, he saw a lot of thunder crystals, but he didn't see the thunder soul crystals. Zichen continued to go deeper, reaching the third level after a few hundred meters.

As soon as he reached the third level, Zi Chen saw a piece of Thunder Soul Crystal, and the thing that this Thunder Soul Crystal turned into was not a thunder dragon, but like a unicorn beast. A piece of Thunder Soul Crystal can refine an immortal strong soldier, and with Zi Chen's current strength, he can definitely refine a human-level peak strong soldier.

You must know that the limit of human beings is the human-level realm, and beyond the human-level realm, it has completely detached itself from the concept of human.

But before Zi Chen could take away this Thunder Soul Crystal, he heard a loud dragon chant resounding from this world. A dazzling silver light pierced through the thunder space and rushed towards the thunder soul crystal in front of him.

"Ding!" followed by a crisp sound that drowned out thousands of roaring thunder and lightning.

I saw a silver spear, directly pointing out a hole in the thunder soul crystal, and the dragon soul mark on the body of the spear continued to glow, and there was also the spread of Dao dragon power. And in the Thunder Soul Crystal, that soul thought is changing, sometimes turning into thunder and lightning, sometimes turning into a strange beast, as if it is struggling.

Under the perception of spiritual thoughts, Zi Chen saw that the soul thoughts in the thunder soul crystal were being devoured by the dragon soul spear.

"It is worthy of being a human-level spirit soldier, and it can sense and devour itself. Looking at the Dragon Soul Spear that was constantly devouring, Zi Chen sighed.

The loss of a piece of Thunder Soul Crystal is naturally a pity, but compared to the Dragon Soul Gun, it is nothing at all.

It took a full quarter of an hour for the Dragon Soul Spear to completely devour the Thunder Soul Crystal, and the Dragon Soul Spear turned into a ray of light and flew back, and the previous Thunder Soul Crystal had lost its soul and became a pure Thunder Crystal.

After advancing for about a few tens of meters, Zi Chen found another Thunder Soul Crystal, but this time the Dragon Soul Spear did not take the initiative to devour it.

This is still a thunder soul crystal that can turn into a strange beast, and there are still many thunder crystals floating around, Zi Chen unceremoniously took everything.

In the entire Barbarian Land, plus the Land of Chaos, it seems that only Zi Chen can penetrate here. Therefore, nothing here has been touched by others, and he can take it as he pleases.

After that, the fourth and fifth levels, Zi Chen gradually felt the pressure when he had gained a lot.

When he reached the sixth level, Zi Chen felt as if he had reached his limit, at most he could advance one more level, otherwise his life would be in danger.

"No, you have to go deep!" Zi Chen paused slightly at the sixth level, then adjusted, and stepped into the seventh level.

This thunder domain is extremely special, Zi Chen can feel the extraordinary, and others can naturally feel it. Nowadays, no strong people have set foot here, one is because there are no strong people in this area, and another reason is that no one in the outside region knows that there is a thunder domain related to the Thunder God Temple.

If you know, there will inevitably be a large number of strong people coming, and even the strong people of the Earth Yuan Realm may be tempted to come.

As soon as Zi Chen stepped into the seventh-level thunder domain, he felt a terrifying pressure coming, this coercion was extremely terrifying, even Zi Chen's perfect body was a little unbearable, his body shook, and he almost fell.

In this level of thunder domain, there are more thunder crystals floating in the sky, densely packed, in addition, there are many thunder soul crystals, these thunder soul crystals are very large in size, and there is a faint fierceness in them.

Zi Chen has seen extraordinary things along the way, and he has seen almost all the heavenly and earthly treasures, but he is still a little dazed when he sees these thunder crystals plus thunder soul crystals in front of him. Because there are so many of them, it can be called a treasure.

Zi Chen raised his foot forward, and as soon as he took a step forward, the pressure around him increased again, and Zi Chen's bones made a clicking sound, as if they were about to break under the high pressure.

"This thunder domain is indeed terrifying, if you come to a human yuan realm without a perfect body, you will inevitably be crushed and unable to move, and you will die here. Zi Chen sighed, but he wasn't worried, the thunder and lightning mark on his eyebrows emitted a brilliant light, forming a golden light shield that protected Zi Chen in the middle.

Zi Chen pushed the thunder mark to the limit, and sure enough, he felt a little lighter, but it was only a little bit that allowed Zi Chen to move. At this level, Zi Chen's perfect spiritual thoughts were also suppressed and could not be detected, so Zi Chen could only hold the purple gold gourd in his hand to collect those thunder crystals and thunder soul crystals.

The purple gold gourd was left by the original human slaughter, and the material is extremely extraordinary, even if Zi Chen arrived at the Renyuan Realm, he did not understand it thoroughly, and it was a great treasure.

Zi Chen struggled forward, his bones kept clicking, and he insisted on withstanding the pressure and completely collected everything around him.

After all the things in the seventh-level thunder domain were collected by Zi Chen, Zi Chen felt that his whole person had collapsed. At this moment, he was in the thunder domain, surrounded by extremely terrifying thunder and lightning, and he couldn't even use his supernatural powers to automatically recover. He could only take out the top-grade yuan liquid and swallow it to allow himself to recover and consume.

After Zi Chen fully recovered, he walked to the edge of the seventh level.

At this point, Zi Chen took a deep breath, but did not immediately step in. The thunder and lightning of the seventh level made him unbearable, and the power of the eighth level was naturally stronger, and if he entered rashly, he would inevitably encounter danger.

After a three-second pause, his spiritual thoughts moved instantly, and the next moment, a roar sounded around Zi Chen. I saw nine tall stone tablets appear around Zi Chen, and then stood side by side, forming a circle, protecting Zi Chen in the middle.

This is a sword monument that is urged by the Nine Extremes Formation, and what is formed at this moment is a defense. In the thunder domain, a loud sword intent came out, and one after another sword light flashed.

The sword light defense blocked the thunder and lightning pressure for Zi Chen, and Zi Chen's pressure was greatly loose, and there was no problem in entering the eighth-level thunder domain.

Although he had a hunch that the thunder and lightning in the eighth-level thunder domain would be even more terrifying, when Zi Chen felt it himself, his face immediately changed. Under the constant raging thunder and lightning, coupled with the terrifying pressure, Zi Chen's Nine Pole Formation was almost broken.

Zi Chen hit the spirit, and the seal in his hand was sealed, and golden light poured out from his fingers, falling on the nine sword tablets one after another. After a while, the sword stele stabilized, but it is worth mentioning that the sword stele did not show the slightest sign of damage in the face of the thunder and lightning bombardment, and its material was beyond imagination.

After the sword monument was completely stabilized, Zi Chen had time to look around. At this moment, he didn't see the thunder crystal, nor did he see the thunder soul crystal, but he saw the thunder liquid like raindrops.

This is exactly the same thunder liquid essence as in the ancient road at the beginning, and what is presented in front of Zi Chen's eyes at this moment is a large area, like dense raindrops.

Zi Chen's mouth grew long, his eyes were round, and his eyes were full of disbelief and shock. The previous Lei Jing and Thunder Soul Crystal did not make Zi Chen have such an expression, but seeing these thunder essences, Zi Chen was completely shocked.

If you say that after Zichen Thunder Crystal and Thunder Soul Crystal just now, Lu Peng and the others who thought in their hearts each held a human-level weapon in their hands. Then the scene that appeared in front of Zi Chen's eyes at this moment was a large group of innate martial artists.

The thunder essence can create an innate martial artist, Zi Chen has experienced it personally, and he also has some thunder essence on his body, and he has not had time to hand it over to Lu Peng and the others. It's just that these thunder essences are extremely limited, and they can only help a limited number of people break through.

But in front of him, the amount of thunder liquid essence, and many Zichen have changed color, it is too much.

"This is indeed a treasure land, a real treasure land! Whether or not my Wuji Sect can rise and become a high-ranking force in the Tianwu Continent depends on these thunder essences. ”

Zi Chen was amazed again and again.

These thunder liquid essences can create many innate martial artists, which can be regarded as great treasures.

The current Zichen has inheritance, resources, and strong soldiers, which can be said to have gathered the capital that makes the Wuji Sect rise.

Although the current Wuji Sect is not comparable to the Wuji Sect back then, it has many resources, and it is by no means comparable to ordinary forces.

What the Wuji Sect lacks now is only a Diyuan Realm powerhouse who can rank in the Tianwu Continent.

Zi Chen manipulated the sword stele, approached the Thunder Essence Essence, and then carefully put it away. Zi Chen had already foreseen the scene when there were a large number of successive Heavenly Martial Artists in the Wuji Sect.

Many thunder essences, Zi Chen collected for an hour, and he also rested once during the period. Because of the manipulation of the sword monument, his consumption is also very large.

After receiving the essence of the thunder liquid, after Zi Chen adjusted it again, he controlled the sword tablet to enter the next level.

Nine represents the limit, and Zi Chen concluded that this is the last level. At the same time, his heart is also full of expectations, what is in this level?

Pieces of Thunder Liquid Essence, or piles of Thunder Soul Crystals?

As soon as Zi Chen stepped into the ninth level, he felt a violent coercion sweeping over, and before he could react, he felt a strong attack.
