Li Ben transmigrates to a fantasy world, where he helps the third prince of Dayong make money, win the succession struggle, and ascend the throne, then helps him defeat rival nations.
The third prince of those days is now the Emperor of Dayong. Seeing that his court is wealthy beyond measure, his foundations secure, and no rivals in sight, he kills the very man who helped him succeed. He not only refuses to honor his original promise, but even fears Li Ben will resent him and decides to kill him to be safe.
At the border of Dayong, just as the executioner's blade is about to fall, Li Ben awakens the War God System. As long as he survives on the battlefield, he receives rewards, and the more dangerous the battlefield, the greater the reward.
Survive a one-star battlefield, and he receives the Black Armor Army.
Survive a three-star battlefield, and he receives the Wei Warriors.
After battle upon battle, when he suddenly looks back, he realizes he has become invincible beneath the heavens.
