Main plot:
I traveled through time and space as a useless substance that was sent to the enemy country Wei. At the beginning, I faced the desperate situation of being tortured and killed by the ninth prince of Wei, but unexpectedly awakened my "immortal body". In order to conceal the secret of immortality and to use "death" to temper my body, I volunteered to guard the most gloomy imperial tomb in the Wei Dynasty.
In the imperial mausoleum, I met the mysterious mute girl guarding the mausoleum. In the sixteen chapters, the plot uses "years" as a knife.
The first four chapters: I kept committing suicide attempts to anger the guards, using every fatal blow to reshape my meridians, and transformed from a loser into a physical genius. The cool thing is that "what doesn't kill me makes me stronger."
Middle section: The external situation is changing. The emperor of Wei Dynasty pursues immortality but cannot achieve it. The prince seizes his legitimate son and blood flows like a river. I sat in the mausoleum with the guardian girl and watched the clouds rise. Every time I died (either by being possessed or accidentally killed by an assassin), my cultivation level skyrocketed.
Climax: The Wei emperor dies of old age, and the ninth prince ascends the throne but is also old. All the enemies who humiliated me in the past have turned into dust, but I still look like a young man, walking out of the imperial mausoleum.
Ending: I showed up at the funeral of my former enemy, smashed the fate of the Wei Dynasty with one punch, took away the girl guarding the mausoleum, and lived a long and happy life.
