Liu He, a college student unable to bear the sting of being mocked for coming in last, grits his teeth and holds his breath through a training exercise until he reaches the end of the Han dynasty. He transmigrates into the body of Liu He, son of Liu Yu, the governor of Youzhou at the time.
With the Han at war against the Wuhuan, Liu He earns a few merits, then his father sends him to Chang'an. He hopes to rely on the emperor, but the emperor is harsh. He then hopes to rely on his father, but a subordinate of his father's named Gongsun Zan kills him.
At last, the dazed Liu He comes fully to his senses. No one in this era can be trusted. He can only rely on himself.
First, he leaves the turmoil of the Central Plains behind and heads west to Fuhan, where he takes in hundreds of thousands of Yellow Turban refugees who have fled there.
After that, he pacifies the lands beyond the frontier, battles Cao Cao, destroys Liu Bei, brings Sun Quan under his command, and is named the imperial heir's elder brother.
At last, the realm is unified. Now it's time to think about expanding overseas!
