Gate of the Dark Abyss

Nine keys open nine gates to the Nether Abyss.

Those who die beyond a gate vanish from reality completely: no one remembers them, as if they had never existed.

Each gate comes with game instructions, and players must follow the rules to clear it.

Items found beyond the gates can be brought back, but each can only be used once.

The farther you go, the harder the gates become, and the more people die.

The killer Hao Hao, code-named You Zhun, unexpectedly obtained the first key during a mission.

Dragged into this deadly game, he discovered that

he wasn't the only one entering the gates in Lin'an City.

There appeared to be nine gates, but in truth there was a tenth.

No one had ever gone in, and no one had ever come out.

What lies beyond it?

Wealth and glory? Another world? Or the truth behind the complete disappearance of everyone who enters?
