Keeping a Low Profile as a Medicine Tester in an Immortal Sect

Transmigration + Xianxia + Simulator + Ruthless + Cunning + Invincible Lead + Golden Finger

Li Xiaoyao transmigrates and becomes a human test subject forced to test medicines for an immortal sect. His life hangs by a thread, and he's treated as less than an insect.

At death's door, he awakens the [Fate Sandbox]. By burning his lifespan, he can simulate the future and every possibility!

[Simulation begins: You refuse to take the poison pill and are killed on the spot by the guards.]

[Simulation begins: You choose to flee overnight and starve to death in the mountains three days later.]

[Simulation begins: You pretend to go along with things, but after your 108th medicine trial, the poison kills you, leaving not even a corpse behind.]

[1,000th simulation: You discover that the cultivation technique practiced by the young lady makes her the perfect furnace for you...]

From then on, Li Xiaoyao walks an invincible path of "knowing the future" through a world full of deadly dangers.

While peerless prodigies believe they have planned for every possibility, Li Xiaoyao has already killed them a thousand times over in his simulations.

When a lovestruck immortal maiden smiles at him, Li Xiaoyao has already seen the killing intent behind every beat of her heart.

Years later, immortals and demons bow before him, and the myriad realms come to pay their respects.

Facing the awe of the world, Li Xiaoyao offers a modest smile.

"Don't get me wrong. I'm not omniscient or omnipotent."

"It's just that... I've already killed you ten thousand times before you even made a move."
