The Ren family has guarded the righteous village for 130 years, and there is a coffin locked in the cellar.
Grandpa left a message before his death: Don't put out the lights, don't open the locks, I'll take care of the account.
That night when the coffin was lost, Ren Jingzhe found out: Lying in the coffin was Admiral Dao Guangnian, the ancestor of the family, who was also two hundred years old.
What sent shivers down his spine even more was the account book - seven years ago, his grandfather sold his ancestors overseas with his own hands.
