(No horror, no harem, no System, no invincible protagonist, and no wish-fulfillment. Please proceed with caution if these are deal-breakers.)
Lin Ang is brought to another world by a door that seems to lead to hell. He wakes up in an apocalyptic game and discovers that he has been taken to a place called the Infinite Flow Divine Domain. A woman has also stolen all the memories in his mind of the life he used to live.
The woman tells Lin Ang that if he wants to recover all his memories, he must enter the game space through the Gates of Hell and take part in various perilous, deadly games.
Just when Lin Ang thinks his memories have returned and he has uncovered the truth behind everything, he is told an even more terrifying truth.
From beginning to end, it has all been a conspiracy, and every game is part of a plot to overturn Lin Ang's understanding of the world.
