Chen Zhe's parents were anti-narcotics policemen in a certain city. They died due to internal leaks during a joint operation. Chen Zhe, who was only 7 years old, was sent to a distant aunt's home in a northern town for foster care and grew up incognito. When he grew up, he joined the army to find out the truth about the sacrifice of his parents. With his excellent individual qualities and meticulous thinking, he was selected into a special operations brigade (codenamed "Dark Blade") in a certain war zone. During this period, he participated in border anti-terrorism and escort operations. However, due to the weakness of "too much obsession" in his character, he chose to retire the year after. And opened a "Philosophical Investigation Firm" in third-tier cities, ostensibly undertaking small businesses such as extramarital affairs investigations and debt recovery.
