The Frail Farmer's Son: Extending My Life with a Forensic System

Lu Yisheng, a modern forensic genius, unexpectedly transmigrates and becomes a sickly young man in the poorest farming family in the Tang Dynasty.

Born with damaged meridians, he was told by a renowned physician that he wouldn’t live past the age of six.

Luckily, the [Forensic Detective Life-Extension System] binds itself to him just in time.

“Ding! Successfully autopsied a woman’s body found in the wilderness and cleared her name. Reward: 30 days of life and a bag of high-yield potato seeds!”

“Ding! Solved a series of locked-room murders. Reward: 1 year of life and penicillin extraction techniques!”

So, in order to stay alive, Lu Yisheng has no choice but to drag his sickly body out in the middle of the night and pry open the killer’s coffin.

The whole village is dumbfounded watching Lu Yisheng cough up blood as he digs up a murderer’s ancestral grave.

A few years later:

“Our neighboring kingdom cries, ‘The Tang Dynasty is doomed, because its national preceptor, Lu Yisheng, just coughed up three liters of blood again!’”

Lu Yisheng quietly glances at the century of life he has left, then at the Tang cavalry behind him, armed to the teeth with modern technology. He gives a cold smile.

“Don’t hold your breath. I can live another ten thousand years. Tonight, I’m going to dissect your emperor.”
