Xuanhuang Account Book

The Su family has been in charge of calculations for generations. They calculate accounts of human beings as well as accounts of cause and effect. On the night of the massacre, Su Yan woke up on death row with his right hand broken, leaving only a bag of counters and an account book. The account says: Use it once and get a wisp of gray hair. But who left the account? No one can tell. What was hidden in that look his father gave him before he died? Is the man standing in front of the corpse with complicated eyes an enemy or a friend? He wants to calculate it clearly one by one. But he didn't expect that this account, in the end, would lead to a door to immortality that should not be opened. There was something waiting for him on the other side of the door.
