I crushed an insect to death, and the system actually said I killed a dragon?

"Ding, congratulations to the host for leapfrogging and killing the Beast King. The reward will increase tenfold, and he will gain immortality and a level of cultivation!"

Listening to the system prompts in his mind, Qin Yang looked at the big cockroach that he had just trampled to death with a confused look on his face.

"Alert! A beast king-level star beast has been discovered. Please run away quickly, otherwise you will die without a complete body!"

Qin Yang looked at the little purple spider in front of him, with a big question mark hanging on his forehead. Do you call this thing the Beast King?

In the library, Qin Yang was reading a book when a little girl walked in.

"Ding, the Empress' aura has been detected. Please kowtow to the master immediately. The future is bright!"

Qin Yang looked at the young girl in front of him who was reading a book seriously, his expression a little stiff.

I'm afraid there's something seriously wrong with this system!
