Without a simulator, without a system, I'm the cheat. I've learned one thing from my short life: the more content you are, the less you gain! (What are you trying to say?!)

Traveling through the Three Kingdoms, he became a down-and-out relative of the Han royal family and intercepted Guan Yu and Zhang Fei at the beginning.

In order to survive in this chaotic world, one can only choose to join the army, go through hardships, cut through thorns and brambles, pacify the Yellow Turbans, be granted a title and appointed as a general, establish one's own territory, recruit civil and military officials, train elite troops, hold power over the world, sleep on the lap of a beauty, and watch the changes in the situation.

When the time comes, I will lead tens of thousands of cavalrymen, ride on mountains and rivers, and swallow up the world like a tiger. I will sweep away all the heroes in the world, unify the country, build the Han Dynasty for the third time, and make the Han Dynasty last forever.

In the howling northern wilderness, Louis Calvin wrapped himself in a wolfskin cloak and stood alone on an ice cliff.

As the son of a duke, he was thrown into this permafrost wilderness by his family in the name of "opening up glory".

He thought he was doomed, but he didn't expect the daily intelligence system to be activated:

[Thirty-seven frozen hungry wolves are lurking in the southeast valley and will raid the territory tonight.]
