Dear Ancient History Expert, What Should I Do? I've Found a Tyrannosaurus Rex

Gu Cheng graduated with a degree in biology and got a job at a paleontology museum.

He had planned to travel the world digging up fossil specimens and studying prehistoric life. Instead, he found himself livestreaming every day to promote the quiet museum.

Suddenly, a viewer in the livestream chat spoke up.

xxx: Professor Gu, I found a creature that looks like a Tyrannosaurus rex. Could you identify it for me?

Then they uploaded an incredibly realistic photo showing a Tyrannosaurus rex as large as a small building.

Gu Cheng took one look and decided that such a life form was biologically impossible. Thinking the viewer was joking, he played along:

"Sure. If one really shows up, I'll report it to the authorities."

A few days later, a mutated Tyrannosaurus rex appeared in Country M. The news set public opinion ablaze, and tens of thousands of netizens flooded Gu Cheng's livestream.

"????"

Afterward, Gu Cheng awakened a System that could calculate the structure of any life form. He began turning one legendary creature after another into specimens and displaying them in the museum.
