I'm My Wife's Bodyguard

Su Bai transmigrated to the world of pirates, only to discover that he wasn't human at all. He was the monster known as Little Peanut from the SCP Foundation, a popular novel from his previous life. And it seemed he had been enhanced more than tenfold.

Fortunately, a chat group for the Myriad Worlds found Su Bai.

Aizen: "You can't be damaged, or even destroyed! What the hell are you?"

Uchiha Madara: "What the hell are you? Susanoo has no effect on you!"

Su Bai could only say that he was helpless too.
