Immortality: I Lived in the Han Dynasty for Four Hundred Years

Gao Changgeng touched something he should never have touched at an archaeological site. When he woke, he found himself standing on a battlefield from two thousand years ago.

He tried to change history: save Han Xin, persuade Xiao He, prevent Liu Bang's death. Every attempt failed. History was like a mighty river in full flood. No matter what he did, it kept flowing as usual.

He refused to give up. He once impersonated Wang Mang and tried to become emperor, only for Liu Xiu to kick him down in one blow.

It took him four hundred years to understand: immortality wasn't a gift, but a seat. He sat in the audience and watched the same play performed twice.
