338 BC, winter. Shang Yang was charioted to pieces by Yu Tong.
In the death row of Xi County, a young jailer, Gu Changsheng, gave the reformer the last bowl of guillotine wine.
That night, Gu Changsheng awakened [Time Panel].
Endless longevity and immortality.
He suddenly understood that in this troubled world, the princes would fight over a city and a pool, and what he fought over would be endless years.
…
He once witnessed Qin Xiaogong's ambitions, and also watched Empress Dowager Xuan attend the court.
He once cooked a bowl of hot porridge for the young man named Bai Qi on the Changping battlefield.
He once served as Lu Buwei's guest, and also taught the child named Ying Zheng how to read and write.
The long years have brought great changes.
The heroes of the past have finally turned into dust, and only Gu Changsheng sits on the long river of time, watching the Qin Dynasty build an empire brick by brick.
"My name is Changsheng. I don't fight for a moment's glory, I only bear witness to thousands of years."
