My Grandpa and I Swapped Bodies

Crime Investigation / Anti-Drug Operations / Counterespionage

Grandfather and grandson switch bodies. No female lead.

During the 2024 May Day holiday, Mou Jianhui decided to take off his police uniform and resign from public service. Then, while his resignation was still awaiting approval, he irresponsibly took an outdoor rescue job and went off the grid.

Meanwhile, the old man, Mou Zhenzhong, had endured an organizational investigation, a stroke, worry over his grandson, and an argument with his son. Then he suffered another stroke and collapsed alone at the public security officers' retirement home.

When the grandson woke up, he found himself in his grandfather's 24-year-old body, fighting bandits and countering spies in the great Southwest. When the grandfather woke up, he found himself in his 24-year-old grandson's body. The rescue had gone wrong, leaving him injured and trapped, his former unit was demanding his return, and, worst of all, something had come up with the case. No one could take his place!

No System. No golden finger. They have none of each other's memories and can only improvise and respond to whatever comes their way. See how the grandfather and grandson handle and resolve the situation.
