Chen Mo, 32 years old, is an elite investment manager of a well-known domestic securities company. He is calm, perceptive and logical, but he has recently been under great pressure due to his involvement in complex financial violations investigations within the company, and even received anonymous threats. He is familiar with financial rules, human games and data analysis, and these skills will become the key to his survival and solving crimes in ancient times.
After a carefully planned "accidental" car accident, Chen Mo woke up and discovered that his soul had occupied an ancient body - the body of a county government official (Zhang Yan) who was silenced for his involvement in a major local case. He retained all of Chen Mo's memories and skills. The opportunity to travel seems to be related to the core evidence of the financial case he is investigating - an encrypted "special account book" that records the flow of huge amounts of illegal funds.
