Sword Art Online - Vol 4 Chapter 0: Prologue

It took Gu Yu twenty years to realize that he turned out to be the vicious cannon fodder male supporting role in a novel.
Forcing the protagonist to sign a contract, and being playful and affectionate, he ended up with his family ruined and his family destroyed.
Just as he was about to establish a good relationship with the protagonist Gong and take advantage of the loopholes in the plot,
Who would have thought that the protagonist Gong in the book, and the ruthless boss who did not get along with the protagonist in the end, was actually his ex-boyfriend who was abandoned by him in high school? !
Oh ho!
Gu Yu: Thank you for the invitation, please don’t bother me.

Gu Yu, who was forced to follow the plot, faced the furious protagonist Gong who seemed to be about to commit murder in the next second. His ex-boyfriend,
With the wife of the future protagonist Gong in his arms, his current gossip partner, he numbly recited the lines: “I warn you, this is my man.”
Seeing Fu Yeyu, who was blazing in the eyes of the opposite party, who could pounce on him and tear him apart in the next second, he couldn’t help but reflect on himself: Why can’t I think about the protagonist’s attack? !

The main attack, the idler should be the heartless attack × the irritable boss suffers
Gu Yu×Fu Huayu

- Description from novelbuddy

A recurring nightmare afflicted Khan's nights since the Second Impact. His dreams replayed the scenes of the crash of the Nak's spaceship, an alien race that the humans had defeated five hundred years ago.

Synopsis is in the beginning first chapter, so you can try to read it first.Zhang Fei is an ordinary human, but he is also an Incubus, and he also a Heavenly Fox.

“Lin Changan, you don’t want to get forced to marry a person, right?” a gorgeous young lady asked as she put a Slave Contract in front of Lin Changan.

Lin Changan was in complete desperation when he received the Emulator System which allowed him to simulate his life.

After each simulation, he could choose to either gain a talent, a realm, battle experience, cultivation, or part of the memory from the simulation.

“You have rejected the Slave Contract and were killed in the Underground City by a love rival.”

“You have chosen the talent, Live a Hard Life.”

“At age 22, your sick junior confessed her love to you and you rejected her. That made her hate you and she poisoned you to death.”

“You have chosen the talent, Complete Poison Immunity.”

“At age 24, you were killed during the monsters’ attack.”

“You have chosen the realm and have gathered the Star Power.”

“At age 24, you fought the monsters’ attack as a general but still died in the end.”

“You have chosen the talent, Restlessness.”

“At age 24, you fought the monsters in the front line but you have exhausted your spirit energy…”

After countless simulations, even the slightest move Lin Changan made could shake the entire world.

“Simulation begins.”

“You are now invincible.”
