No system! No era! A secret formula recorded in a medical classic boosted his company's market capitalization to over one trillion yuan, only to be persecuted by a scumbag woman that very day. In his dying moments, he recalled himself thirty years ago: a year in which he neglected his family for his mistress, a drunk, card-playing, domestically abusive man who even gambled away his daughter's surgery. All that ended when his distraught wife, driven to suicide with their daughter, drowned herself in the river. With his death, he returned to that day. When he opened his eyes, his wife and daughter were both there. "Tang Yuxin, I owe you so much in my last life. In this one, I will protect you from any wrongdoing."

In his previous life, Zheng Chuan, who worked as an undercover agent, personally sent his criminal father-in-law to the execution ground. What he didn’t know was that his wife, already pregnant at the time, suffered a miscarriage from heartbreak. In despair, she jumped off a building. The moment she fell, Zheng Chuan lunged forward, and the two of them plummeted from the seventeenth floor together.

When he opened his eyes again, he had returned to ten years ago.

On one side was the chance to restore his father’s police badge—an honor and duty as a police officer. On the other side was a father-in-law who valued loyalty and righteousness, and a mother-in-law who treated him like her own son. And then there was Shen Li, who deeply loved him, and the two children who never even had the chance to see the world.

How should he choose?

Is this world truly black and white?

A mission? Uphold justice and punish evil?

To hell with that…
