Cloud City, the crown of emerald, carrying a golden coffin, noletis came here.

Under the devil fruit tree, Sean frowned at what noletis had brought back.

"Brother, I can't kill this thing. I can only bring him back."

Seeing Sean's frown, noletis explained that although he defeated the monster in the sea of death, he tried several methods, but he couldn't really kill the monster. There was no way, he could only bring him back.

Hearing this, Sean didn't say anything, because even if the thing itself was not alive, it was not easy to kill him completely by ordinary means.

"I am immortal. I am immortal. You can't kill me."

Consciousness suddenly woke up, empty eyes opened, and the strange figure roared ferociously.

Seeing such a scene, Sean was motionless. There was a touch of light in his blue eyes. He was neither born nor dead. The strange state of the monster really aroused his interest.

"It's interesting to be able to speak common language, but it's a pity that I'm crazy."

It's a pity for Sean to feel the mental fluctuation of the monster. If the two sides can communicate, they may have more gains, but now it's also good.

Hoo, the cold breath filled the air. Jiugouyu's reincarnation eye became apparent. The virtual shadow of the God of death appeared behind Sean. Looking at the monster who had not died but was temporarily trapped in the coffin, the God of death licked his bright red tongue and made a strange laugh.

"Pull out his soul. I need his memory."

Hearing this, he aimed at the monster in the coffin, and death stretched out his palm.

"Ah!"

When death's claws pierced the monster's body and pulled back, a trace of dark smoke emerged from the monster, and there were twisted souls.

Seeing such a scene, a touch of disgust flashed in noletis's eyes.

The big mouth opened, frowned and swallowed all the souls. The God of death launched the shallow ability of human Tao and heart and began to read the memory of these souls.

Although there are many souls pulled out of the monster's body, with a number of more than 10000, most of the consciousness has completely dissipated, leaving only the purest resentment. Only the consciousness of the original owner of the body is really sober.

After reading the memory, the ghost of death disappeared. Sean frowned at the monster who had completely disappeared from the coffin.

"Undead Kingdom, El people, pyramids, mummies."

One thought after another, and Sean's eyes drifted away.

In the silver age, a human race traveled across the sea to the new world, and then established a huge kingdom here. This kingdom is the desert kingdom, also known as the kingdom of immortality, because all people from top to bottom are pursuing immortality here.

In order to pursue immortality, the country made many attempts. Later, their leader, the great sage respected as the first Pharaoh, finally grasped the true meaning of immortality through continuous understanding, summarized the method of immortality, and spread the method of immortality in the country.

The pyramid is made of blood stained sand and stone, the life is sacrificed, and the pure gold coffin is used to bury yourself. After sleeping through time, you will never die. This is the immortality method of the immortal country.

For this method, the people of the undead country have no doubt, because the great sage himself has completed and achieved immortality. In this case, pyramid after pyramid began to appear on the land of the undead country.

Of course, the people who can build pyramids are not ordinary people. They are all the nobles of the undead country. The monster brought back by noletis is one of them, but he has forgotten his name.

"Why do I always feel a little wrong? The so-called immortality seems to be more like a ritual."

Sean frowned as his eyes turned.

From now on, the immortality of the undead country seems to be successful. At least the monster in front of him has "lived" from the silver age to now, but there are huge defects.

"It's a bit like a zombie. It's neither life nor death. It needs to rely on blood food to complete recovery."

After reading the monster's memory, Sean had a certain understanding of the so-called art of immortality. He isolated the inside and outside with the pyramid, which was both protection and bondage. He let the living life die. With their resentment and unwillingness as food, he took the curse as a good medicine to promote his own transformation, built a coffin with pure gold, sealed everything, and let the flesh and blood sublimate without interruption, Become immortal, and this form is also called mummy.

This way can really keep people's consciousness in the flesh, isolate the influence of the spirit world, prevent the soul from being captured by the spirit world, and obtain an alternative immortality. However, after completion, it can no longer be called a person, but can only be described as a monster. Moreover, after sleeping into an immortality, if you want to recover again, you need the baptism of fresh flesh and blood, and only get enough flesh and blood, Mummies can be reborn from death and walk out of the mausoleum.

The reason why the monster brought out of the dead sand sea by noletis fell into madness was that he had not completed this step. At this time, he lost the protection of the pyramid. His mind could no longer bear the unwillingness and resentment of countless people. He lost himself in the dark and completely fell into madness, leaving only the idea of immortality.

Of course, even if you are reincarnated from death, you are not really a living person, but a fallen soul has a relatively fresh body. In order to maintain this freshness, the undead must continue to absorb fresh flesh and blood. This will be an endless process. Once it stops, the undead can only return to the pyramid and sleep again, As for whether you can wake up, no one knows.

"So the salt mine in the dead sand sea is the bait prepared by the undead?"

Combined with the memory of the undead and the situation reported by noletis, Sean has a deeper understanding of the existence of the dead sand sea. It is obvious that the things in the dead sand sea are arranged in advance, and the purpose is naturally to attract people to search for treasure after the transformation is completed and the dead sand sea emerges, so that they can become the rations for the undead to wake up. It is a simple but effective strategy.

Take the dead sand sea in riprap beach as an example. If LVYE city didn't intervene and take the treatment method of Blackstone tribe, it won't be long before the undead body in the pyramid can recover. At that time, maybe it's time for the dead sand sea to melt into the main world and the undead body to get out of the pyramid.

"It's neither a secret place nor a fragment of the world. With such a pen, it seems that the immortal country was really not simple."

His eyes turned and he thought of the particularity of the death sand sea. Sean was a little interested. It was a pity that the death sand sea on the riprap beach had been integrated into the main world after noletis completely destroyed the pyramids inside.

"Noletis, next you go to the riprap beach and sit in town for a while. I'll ask snow to send people to mine the salt mine there."

As the thought turned, Sean decided that since the dead sand sea had been integrated into the main world, the salt mine would naturally be occupied. After all, it was not of low value. As for what was hidden behind the dead sand sea, Sean planned to give it to white beard and shadow to investigate.
