The cracks in space and time opened wide, monsters poured in in large numbers, and humanity was completely destroyed.
Lu Chen, one of the top combatants of mankind, unfortunately died tragically while leading their team to fight against the Demon King in the Forbidden Land.
When Lu Chen opened his eyes again, he found that he had come out of the rift in time and space, but his soul was possessed by Lu Chen, a high school student who had just been bullied to death. At this time, more than fifty years had passed in the outside world.
In order to fulfill his last wish and avenge this high school student, Lu Chen cooperated with a strange creature named Sark that he brought back from the forbidden land.
Sark was responsible for converting the monsters Lu Chen killed into energy and providing it to him, while he was responsible for seizing some systems in the human body to repair Sark's body.
...
"Hahaha, let me tell you the truth, I have a system, I am the son of destiny, I am invincible."
After a while, Lu Chen looked at the dying "system operator" lying on the ground and said regretfully: "Oh, why are you lying to me? You have a system and you are not invincible. If I had known better, I would have struck more lightly."
