The old man's memory is so bad that he doesn't even know his name, but there seems to be a voice in his mind calling him old Wu.

According to Wu Lao's scattered memory, Yu Wentian probably knows how Wu Lao came to the Styx river.

One day about 300 years ago, Wu woke up and saw a strange himself. He didn't know who he was or where he was. People around him called him Wu, but he didn't have any feelings.

In this way, after a long time, he knew the world again, and he also knew that his cultivation was very strong, but he didn't know where his cultivation came from.

At the beginning, it was ok, but it couldn't affect him. It didn't matter if he couldn't remember. What he forgot proved to be unimportant.

But with the passage of time, he felt more and more wrong. There was a demon in his heart, which hindered his practice.

He repeatedly tried to expel the heart devil, but he couldn't know the origin of the heart devil, so he couldn't get the heart devil. He could only let the heart devil haunt the Tao.

Old Wu felt that not only did he not improve his accomplishments, but he also had a retrogressive trend. This would not work. He could not accept such a thing happening to him.

In the mouth of an old wise man, he learned that there was a river called Jichuan in the underworld. As long as he drank Jichuan's water, he could remember all his memories.

After many difficulties, Wu finally came to Jichuan with an attitude of trying. He was excited and drank a mouthful of Jichuan water. However, it was useless. He still couldn't remember everything before. He didn't give up. He didn't expect to sit in Jichuan for 300 years.

"Little brother, have you forgotten your future and past, come here and have a drink of forgetting Sichuan water?"

Yuwentian shook his head. "Back to the elder, the younger generation didn't come here to remember the previous things. The younger generation hasn't forgotten the previous things. The younger generation came here to practice."

Old Wu's spiritual consciousness nodded at the midpoint of his mind, and the old voice came again, "Oh, I haven't forgotten. The memory of previous lives can't be remembered. You'd better give up."

Yuwentian has a black face and a group of black crows on his head... No, it should be a group of black Luo Zha and yecha flying around. He and Wu Laogen are not on the same line.

"System, you get out of here. What's the challenge of Sichuan?"

Yu Wentian scolded the system for a long time in his mind, and the system finally got out.

"Back to the host, the data show that this Jichuan is the first weight of the Styx river. It was once guarded by Luocha and yecha. Only three hundred years ago, this old man, yecha and Luocha, dared not go upstream of Jichuan. This old man became the guardian of Jichuan."

"Don't give me these theoretical things. I just want to know how to start remembering Chuan's experience. Go and find it for me quickly, or I'll tear you down immediately."

"It's easy to challenge. Just drink Jichuan's water. And remind the host that it can't cause any damage to the system with the power of the host."

After that, the system sank into the sea again. No matter how Yu Wentian called in his mind, he could not contact the system.

"Shit, it's like this every time. What broken system can't be relied on at all."

Yu Wentian came out of the sea and looked at the old man again, "senior, if the senior doesn't mind, the younger generation will take a mouthful of Jichuan water to drink."

After that, yuwentian raised his hand, and a water ball rose up in Jichuan water and fell into yuwentian's hand. Yaotong looked at Jichuan water, still flashing a dark cyan light, and could not see anything else.

Yuwentian nodded, "it's worthy of being the river of the underworld. The first weight of medicine pupil is useless."

I can't care too much. Since Mr. Wu has been drinking the water of forgetting Sichuan for 300 years, there are no serious consequences. He shouldn't either.

He put the water ball into his mouth. Before he could wriggle the joints of his throat, he had legs. He walked directly into Yu Wentian's body from the innermost part and through his throat.

Seeing that yuwentian drank the Jichuan river water, old Wu finally raised his head and looked in the direction of yuwentian. However, at this moment, yuwentian had closed his eyes and could not see old Wu's face.

There is another thing that old Wu didn't tell Yu Wentian, which is why he has been here for 300 years.

In these three hundred years, there are many evil people who have the existence of the underworld to practice here or cross the river from Jichuan. After drinking the water of Jichuan, they can remember the previous things, but he is a special existence.

Later, he thought of a possibility, that is, for the other world, it is all undead, and he also has body, which is different from the structure of undead here. Maybe this is the reason.

However, no living person like him has come here for 300 years. He has always been unable to verify the conjecture in his heart, so he has waited here for 300 years. Now yuwentian has come, and he can finally verify the idea in his heart.

Yuwentian woke up slowly in a world of nothingness. Yuwentian struggled to open his eyes. It was dark all around, but the faint outline made him feel very familiar.

But he felt a lot of pain in his body, as if he had been seriously injured. When did he get hurt? Yu Wentian knocked on his head, which was the most painful place.

"I seem to have forgotten something very important. What is it? Why did I forget it? What is he?"

After a while, there was a burst of dawn in the sky, and a new sun appeared on the horizon, sprinkling the fire red light on the earth, and the whole earth appeared new vitality again.

This is the southern region destroyed by him. It has become a hell on earth before, but now it is the beginning again. Everything around is new, new monsters and new vegetation.

He met many monsters on the road, met the mantis, robbed the apple with the mantis, and met the little white rabbit, but the little white rabbit jumped away, thinking he was going to rob the carrot in his hand.

Finally, in a secret place, the essence of the southern region was found. It was a sculpted chaotic appearance hanging over a lake under a waterfall.

This is the essence of the southern region that he is looking for. Yu Wen Tian is very excited and agitated, reaching out to explore chaos. When he is about to touch chaos, Yu Wen Tian is like an electric shock that takes his hands back and stares at the chaos sculpture in front of him.
