- Description from novelbuddy

Being sucked into a fantasy world that nobody leaves doesn't sound half bad to Cain. He was a high school dropout with a drinking problem, living off disability due to his poor health, so it's not like he had much to lose except a few faithful friends he didn't talk to enough.

After a long night of drinking, Cain wakes up looking at what he believes to be the character creation screen of one of his beloved virtual reality games, but with no recollection of having purchased it. His unwitting choice to use the Random Character Creation option, unaware that the choice would be irreversible, sends him into this new world as a Puppet Master, a Summoning based class nobody else in the starting zone has ever heard of.

But as he soon realizes, this is no game, him and hundreds of others have been brought to another world with no instructions, no clear goals and no way home. It's a second chance to live a good life, but what will Cain be able to make of it?

“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.”
