Marvel: I'm Just a Security Guard, Yet I'm Asked to Keep Earth Safe

After transmigrating to the Marvel Universe, Su Xing awakens the Security Guard System. He thinks this security job will be like the one he remembers from his previous life: an old neighborhood guard who sips tea and clocks out on time. But the System's message leaves Su Xing dumbfounded. What the heck? The whole Earth is under my protection? I'm just a security guard, and you want me to keep the entire planet safe?!! Years later. Iron Man: Stop looking at the security guards. I'll pay you. Be my personal bodyguard from now on. Hydra: What the heck? We're suspected of endangering public safety, and you're arresting every last one of us? Loki: I was wrong, big bro! Security guard! I'm leaving right now! Thanos: Are all the security guards on Earth this tough...?
