I Can Change Everything in the World

I was cursed and had to rely on painkillers to fall asleep every night. My life was in the hands of others. But it doesn't matter, the big guys want to control me and make me work hard, so I will put on a mask, be a dedicated undercover agent, and play them into hell. Technology, cultivation, spiritual treasures, crystal armor, various forces, and human resources, as long as they can help me defeat the two cancers and help me get revenge, they are friends.
