Genshin Impact: I am best at sacrifice, don't cry

Ikaros looked at Nan Dou's leaving back, tears flowing uncontrollably from his eyes.

No one would be as decisive as Nan Dou to let them go. Thinking of the care Nan Dou had given them, Ikaros couldn't help but kneel down on the ground and kowtowed deeply to Nan Dou.

Nan Dou was fully aware of everything that was happening behind him, but he did not look back, which was not a difficult thing for him.

And as Ou Ya gradually revealed more information, he learned that the opportunity Ou Ya was waiting for was actually related to Kan Ruiya.

So in fact, he also needs to know the location of Kanriya now. It just so happens that Ikaros and the others appear, which saves him from further effort.

However, he did not lie to Ikaros about one thing. The necklace he gave him did serve to call him, but it could also help him locate Nan Dou.

Nan Dou returned to his own laboratory, looking at the researchers moving around, and sighed deeply: "Child of the world, there is no body in the mortal world that can accommodate her noble soul."

Yes, Nan Dou's experiment that lasted for thousands of years has been completely declared a failure. No matter how powerful the demon god is, the body copied from his genes cannot become a qualified container for the Eurasian soul.

So many years ago, Nan Dou's laboratory became a research site for biological mechas. Relying on past experience, the biological mechas have been successfully developed and continuously updated and iterated at an incredibly fast speed.

However, Nandou does not intend to let the public access the biological technology for the time being. Therefore, no one knows about these biological weapons except the senior management of Liyue and relevant industry personnel.

……

One year later, in a monster tribe in the wild of Liyue.

In a luxurious cave.

Nan Dou walked into the cave step by step, and what caught his eyes were specimens that had long since turned into skeletons. Many of them were very familiar to Nan Dou, but all of them were powerful monsters when they were alive.

Nan Dou's footsteps were light, his face expressionless, and a low pressure surrounded his body. Anyone could see that he was not in a very good mood.

Inside the cave, there was a nest that looked very comfortable, made of some kind of monster fur. An old, gigantic black panther was lying quietly in the nest.

After hearing the noise, Lei opened his eyes with great effort, revealing cloudy and exhausted pupils, and watched Nan Dou approaching quietly.

"Lei, I didn't expect this day to come so soon."

Nan Dou walked to Lei's side, stretched out his hand and infused some vitality into him, but it was obvious that Lei, whose life was coming to an end, had a body like a sponge full of holes, and no matter how much vitality Nan Dou infused into him, it would dissipate very quickly.

Nan Dou knew this, but he never stopped what he was doing.

After being infused with vitality, Lei regained some strength and said, "Teacher, thank you for your teachings over the years. There is no need to be sad now that my life has come to an end."

"I fought for Liyue all my life. After the Demon God War, I was originally alone. But now I can create a tribe and have many children and grandchildren. I am already very satisfied."

"Before I leave, I can see my teacher one last time. I have no regrets."

A satisfied smile appeared on Lei Laomai's face.

Nan Dou had mixed feelings. He knew that his student had died of old age, but every time someone left him, he couldn't help but sigh.

When Lei became his student, he was already able to stand on his own. If you say he taught him something, it was quite a lot, but it was definitely not to the extent that a teacher is a father for life.

But after Xiaoguang and Lingyun died, Lei secretly broke the rules several times in order to avenge them, and massacred the territory of the Dream Demon alone. However, the Dream Demon had already escaped at that time, and the furious Lei only killed some followers who were unaware of the truth.

After that, Lei was always available when called upon. Although Nan Dou didn't need him many times, his attitude was still fresh in his memory.

Although Lei possesses the strength of a mid-level demon god, he is not a demon god after all, and he does not have the long lifespan of the innate immortals.

The reason why he is still alive today is entirely due to Nan Dou constantly using the Tree of Life to strengthen his vitality.

"I will bury you next to Xiaoguang and Lingyun. Your brothers and sisters are all there."

Nan Dou felt Lei's increasingly weak breath, and tears welled up in his eyes.

"Teacher, thank you..."

Lei's breath weakened rapidly and his eyes gradually closed.

"Hey……"

Nan Dou sighed, collected Lei's body, and walked out of his residence with a sad look on his face.

Lei's tribe has long been on the right track and is one of the most powerful wild monster races in Liyue.

According to the rules of Lei, only those who are recognized by everyone in the clan are qualified to be given a name, and the best among them can be given the name [Lei].

When Nan Dou walked out of Lei's residence, the elders and wise men of the Black Panther Tribe gathered outside and waited quietly.

Nan Dou looked at the black panthers, who were Lei's great-grandchildren, and finally felt some love for them. He threw a gem engraved with many complicated spells at one of them.

"Give it to the most outstanding child in your tribe. He will be able to save its life in a critical moment."

After doing all this, Nan Dou had no more attachment and turned into a wisp of breeze, disappearing from the spot with Lei's body.

Strictly speaking, except for Ling who has become a demon god, all of Nan Dou's students are dead, and Lei is the last one.

When he reappeared, Nam Doo came to a hillside covered with sunflowers.

Nan Dou silently dug a hole with his hands, little by little, put Lei's body in it, covered it with soil, and a grave was made.

Nan Dou personally condensed a stone tablet from rock elements that would not weather for tens of millions of years, and personally engraved Lei's name on it.

After placing the tombstone, Nan Dou stood up with satisfaction.

A gust of wind blew, and Nan Dou's sight swept across the hillside in front of him. Stone tablets were neatly arranged on the entire hillside.

"Xiao Guang, Ling Yun, everyone... is here."

The sunflowers all over the mountains swayed slightly in the wind, as if Nan Dou’s deceased students were responding to him.

"From now on, the teacher will also fight for this beautiful world. You just stay here and watch over the teacher..."
