Yu Ji is a mermaid.
When he first came to the human world, Grandpa Turtle found him a job. He watched TV series with the old humans to relieve their boredom. The TV series made Yu Ji cry so much that Yu Ji accidentally dropped a small pearl, which was also seen by humans.
Not only did that human not expose him, but he also helped him cry for Little Pearl. He was really a good person.
Grandpa Turtle who came back from vacation: Why are you with that living King of Hell!
Yu Ji said in confusion: He is so nice!
Grandpa Turtle hates iron: he is close to you just to capture you for research! He's from the Non-Human Research Institute, and you're screwed.
Yu Ji was so spineless that he was scared to tears——
Yu Ji packed his luggage overnight and prepared to return to the ocean to save his life.
As soon as I stepped out of the door, I was stopped——
Yu Ji: Can you stop eating me?
Lanqi: Maybe not now.
Intention: Use dreams as horses
