Reincarnated as an Old Man: The Ultimate Life Extension Hacks

After dying in his first job, Li Jianguo transmigrates into an elderly man with terminal cancer. Bound to the 'Max-Level Grandpa Hacks System', he must sign in daily to extend his life. His first stop is the Shan Shui Manor, where he accidentally collides with law enforcers Tan Tan and Zhao Meng during an anti-prostitution raid. Mistaken for a prostitute, he panics and claims to be learning a foreign language. In the manor's hall, his superior language skills allow him to decrypt a spy's password book, helping the enforcers secure crucial clues and proving his innocence. Successfully completing his first hack, he gains ten days of extended life and enhanced physical attributes.
