I'm an Eighty-Year-Old Licensed Worker, and Cancer Is My License

Ye Tian was reborn, only to have fate play a cruel trick on him. Not only had he become a lonely old man in a nursing home, but a doctor had also told him he had terminal brain cancer and not long to live. Just then, a System notification rang out in his mind! Ding! [Congratulations, Host! You have successfully bound yourself to the Old Geezer Comeback System!] [As long as you speak up for justice, you'll earn Justice Points, make a powerful comeback, and reach the pinnacle of life!] [Justice Points can be exchanged for items such as lifespan, skills, props, and money.] [Your current remaining lifespan: 4 hours] Ye Tian's eyes lit up. This was exactly what he needed to turn things around! Eighty is the perfect age to care about the world and go out there to make a name for yourself! "You don't dare hit me, so why are you raising your fist?" "I'm eighty! The prison won't take me!" "Did you leave your vocal cords at home or something?" "Go ahead, touch me! I dare you! I'll die right in front of you!" From then on, Donghai City had a new “outlaw” who wouldn't stop speaking up for justice!
