The Human Legacy Has Been Lost, So How Did You Become an Emperor?

In this world, demons have overrun the human realm. Humanity's knowledge has been lost, and its civilization has been utterly destroyed.

With everything taken from them, humans are kept as livestock by demons, and the end of their lives is to become food for their captors.

Li Che transmigrated into this despairing world.

In three days, he would either be slaughtered or become the pet of some demon.

Fortunately, Li Che gained the extraordinary ability to project himself into the past.

Over those three days, he repeatedly explored possibilities throughout history.

He learned countless abilities that humanity had once passed down through the ages.

And he changed the fate of humanity, preventing its civilization from being wiped out time and again.

So when the demons opened their underground breeding pens, ready to take the humans inside to slaughter, they were horrified to find that the people they'd once been able to butcher at will had become so powerful!
