Riding out the apocalypse on a tropical island isn't exactly a vacation. When mana arrives on Earth, Coop finds himself isolated in paradise with only one real option to survive. He needs to claim a civilization shard and level up. Coop maximizes his chances by carefully selecting a class and committing to progression. He’ll need to grind thousands of monsters to compete on the system's leaderboards while upgrading his settlement to represent the factionless.

Zhu Tong was born in a wealthy family, but the pampered young master suffered from a serious cleanliness addiction, and there were so many things that even God can’t stand it, so he was given a sickness and even coughed three mouthfuls of blood.

The day before his death, he was inexplicably bound to a system.

The system told him that he was actually a cannon fodder villain in a danmei novel who humiliated the heartthrob protagonist and suffered the consequences. If he wanted to survive, he had to find the only one in the novel, the white moonlight, who was not attracted to the protagonist and get full favorability from him.

In order to find him, Zhu Tong changed schools.

The new school was located in a remote small county with eight-person dormitories, a canteen for big pot meals, and only one public toilet in a teaching building.

Zhu Tong: In order to survive, he will endure!

However, one day two Shogunate ninja approach him with the news that his four students have gone rogue and have stolen a portable modular nuclear reactor, and thus they ask for his help in bringing his students to justice.

In this world, there is the beautiful mutual and telepathy love.

“I’ve been pursuing you for so long, what do you think?’

Xu Xu could feel her heart pounding in her chest; however what he said wasn’t logical.

“You’re pursuing me?”

Ji Bai raised his black eyes looking at her quietly.

“Every morning I exercised with you, personally taught you how to shoot, prompted the police team to call you sister in law… If this isn’t pursuing, then what is it?”

She took a deep breath stabilizing her heartbeat.

“You don’t need to pursue me anymore.”

Ji Bai totally did not expect her to say that. His heart sank, coldly said: “What do you mean?”

Xu Xu looked into his eyes: “I also like you so you don’t need to pursue.”
