How Can There Be Such a Side Job?

After counter-killing the time traveler, Chen Zhen was recognized by the script system and became a passerby character. System: You must serve as a stepping stone for the protagonists and achieve their supreme achievements. Chen Zhen: It's a good strategy, but I want to make some modifications. From then on, the protagonists in all the worlds collectively broke through their defenses. A certain son of luck: In the eyes of others, I am the protagonist, but in the eyes of Brother Chen, I am just a beggar. A reborn person: You bullied me before I was reborn, and you still bully me after I was reborn. Didn't my rebirth go in vain? Protagonists: Chen Zhen, you must have taken a kickback from all the benefits given to us by the will of the heavens! Will of All Heavens: Why are the protagonists so bitter recently? Do you have any clues? Chen Zhen: I don't know.
