Lin Jiu just wanted to deliver food safely, but the Zangzhuo system he was bound to didn't allow it. Keeping a low profile can accumulate rewards, but as long as someone denies him three times in public, the system will force a hidden identity to be exposed. At the wedding banquet, he was ridiculed for having nothing, but all the hospital directors in the city called at the same time; the wooden sign was trampled to pieces, and people from all over Jiangcheng arrived overnight; he went to work as a cleaner at the university, but the International Mathematical Union connected the scene for him. Miracle doctor, capital helmsman, specially appointed professor, top engineer... The more Lin Jiu tries to keep a low profile, the more outrageous his vest becomes. Faced with everyone's shock, he always had only one sentence: "I'm just a food delivery guy."
