The system will automatically match the strongest people around to complete the task for the host! Puppet: Can I refuse? Zhou Xingchen: You refuse to try! Heaven's thunder punishment will come immediately, and if it is not completed, it will be directly obliterated! Puppet: I'm going to kill you! Zhou Xingchen: You can't kill me. I have invincible defense and can bounce back your attacks six times! The puppet bites the master, and the thunder punishment from heaven is doubled! If you don't complete the task, kill the puppet! I have immortality, invincible defense, and the strongest puppet to help me. How do you deal with it? (No brainer, no brainer, please move to the main text!)
