The power of the derivative realm lies in the ability to be reborn with blood.

However, when Xiao Zheng used his sword energy to directly destroy Satan's body, he had no chance of rebirth and was directly killed. As for Xiao Zheng, he was exhausted and collapsed on the ground.

It is actually a bit lucky to win the battle.

If Satan had not been smart, he was mistaken for his intelligence, and he thought that Xiao Zheng could not defend himself after he hit the Night Eternal Violation, and the battle would not have ended so quickly.

After a while of rest, Xiao Zheng's face finally looked a little better.

At this time, with Satan's death, the army of undead that was still rushing like a tide fell to the ground in an instant. With a ray of breeze blowing, these bones instantly rotted into ashes and then blew away by the wind.

The army of the undead and Satan prospered and suffered losses.

After Satan died, they naturally couldn't live anymore.

"It's finally over."

"If Satan hadn't lie, I should have been able to leave here now, right?"

Xiao Zheng looked at the sky, and the light curtain covering the entire underworld was melting at a speed visible to the naked eye. First, a ray of sunlight came in, and then it was like a light suddenly lit up in the dark room, making people feel a sudden enlightenment.

His previous guess was correct, it was indeed a hundred thousand mountains here.

The reason why Xiao Zheng did not discover the existence of the underworld before was entirely because of the light curtain. Now that the light curtain has disappeared, the underworld has completely disappeared. He can now rush back to meet Long Qi and the others at any time.

However, Xiao Zheng did not intend to leave just like this, and his eyes fell on the Death Mountain.

To be more precise, it fell on the ancient castle.

Because she had obtained a golden bone from the underworld, Xiao Zheng believed that there must be more golden bones hidden here. Maybe there are golden bones in the ancient castle where Satan lives.

After retracting his clone, he flew towards the castle.

When you walk into the castle, the air inside is filled with a rotten smell.

In fact, the castle is not large in size and there are not many rooms.

After Xiao Zheng opened his perspective, he could quickly investigate the entire castle. His eyes flew across every room, and finally found a secret room under the castle.

There is only one desk in the secret room, and next to it is a futon.

Obviously, Satan usually goes into seclusion here.

When Xiao Zheng walked into the secret room, he first found a diary in his desk, and then in another drawer, he found what he was looking for.

There are four golden bones in total, and they are lying quietly in the drawer at this moment!

Xiao Zheng's eyes were hot and his heart was very excited.

This trip to the underworld, he has definitely gained a lot.

He got five golden bones in total. This efficiency was definitely something that Xiao Zheng didn't even dare to think about before!

After collecting these four golden bones intimately, he opened the diary.

The diary is full of Satan's handwriting, which also allows Xiao Zheng to know the secrets of the underworld.

It turns out that the birth of the underworld is closely related to the ancient world.

The undead tribe where Satan was originally an ancient tribe, but more than 1,200 years ago, the undead tribe committed public anger, causing other ancient tribes to start encirclement and suppression of the undead tribes.

A big battle occurred between the two sides, and countless strong people were killed or injured.

In the end, the ancient clan coalition won the victory, and Satan became the last member of the undead tribe. He and this battlefield were sealed together forever. The reason why Xiao Zheng was able to see the giant clan and the witch clan appear in the underworld was because of this war.

After being sealed, Satan made all his former enemies into puppets and then enslaved them by his side.

The diary also revealed a message to Xiao Zheng, that is, part of Satan's strength was actually sealed to maintain the operation of the light curtain. After learning the news, Xiao Zheng was shocked and sweated.

"Fortunately, Satan's strength has been sealed. If his strength is not sealed, it is hard to say who will win or lose in this battle!" Xiao Zheng's eyes were full of solemnity, and he felt a little lucky in his heart. "It seems that with my current strength, it is not enough to kill a truly powerful man in the derivative realm!"

"I must get more golden bones. Only in this way can my strength become stronger!"

Then he continued to read the diary.

The end of the diary brought him another huge surprise.

On the last page of this diary, there is information about the ancient world. It turns out that the barriers entering and leaving the ancient world are not only the two barriers of the 100,000 mountains and the Kunlun Mountains. There is also a barrier hidden on an isolated island overseas.

This barrier is the biggest secret mastered by the Undead.

In addition, the diary also revealed.

The reason why Satan left the map of the isolated island in his diary was to wait until one day he could break the seal and then lead the army of undead back to the ancient world. Unfortunately, he is dead now, and this map fell into Xiao Zheng's hands, which is the second gift Satan gave him.

"If the map is real, maybe I can use this third barrier to attack the ancient clan!"

"This great gift Satan gave me is really not light!"

He then closed his diary, turned the qi into fire with his fingertips, and directly burned the diary.

Anyway, the map has been left in his mind, and there is no need to stay in this diary.

Xiao Zheng then checked the castle side and confirmed that he had not missed anything useful, he got up and flew away from the castle and flew towards the direction where the Temple of the Pluto was located.

The feeling of seeing the light of day again made him feel very comfortable.

Half an hour later, the Temple of Pluto appeared in Xiao Zheng's sight.

At this time, Hades was sitting in the temple to sort out the information he had collected recently. When she suddenly felt a powerful aura outside approaching quickly, a murderous aura flashed in her eyes.

"Did the people from the ancient clan come again so soon?"

Hades murmured, and then her figure disappeared from the temple.

When her figure appeared again, she had already arrived above the Temple of Pluto.

But soon, the murderous aura on Hades's face was instantly replaced by surprise.

She never expected that the powerful aura she had just sensed actually came from Xiao Zheng!

"I'm back!"

After Xiao Zheng flew to her, he took the initiative to say hello to her.

Hades was still stunned, not knowing what to say.

Seeing this, Xiao Zheng couldn't help but smile and said, "What's wrong? Why don't you talk? We haven't been separated for long, right? Why do you suddenly feel like you don't know me anymore?"

"No..." Hades finally came to his senses, but his inner shock still did not subside.

Xiao Zheng smiled again and said, "I know you must be very curious now. I want to know where I have been to these days. But this is not a place to talk. Let's go to your temple first. It happens that I have a lot of things to tell you."

Hades nodded, then followed Xiao Zheng toward the temple.
