"Let me take a look."
He Ao stood up and walked towards Zhang Yusi.
Zhang Yusi handed him the bullet she was holding.
He Ao, using the light from Zhang Yusi's flashlight, meticulously examined the bullet head.
The bullet had severely deformed, completely flattened, with the engraved serial number on the bottom twisted beyond recognition, leaving only a few partially discernible letters.
He Ao bent down to where Zhang Yusi had just found the bullet.
It wasn't lodged in the flesh of the monster, but caught in a crevice between the roots of its tentacles.
The bullet hadn't penetrated the monster's defenses but had lodged itself perfectly in the crevices of the monster's surface and was preserved.
"Do you know a lot about firearms?"
He Ao handed the bullet back to Zhang Yusi.
"I'm the champion of the Beidu shooting competition," Zhang Yusi replied with a faint smile as she took the bullet back, "I'm familiar with every firearm at the Research Institute."
