503: it’s too late to regret! 1

The assistant found it strange that the exotic beast was able to return on its own.

Logically speaking, the experimental base was like a cage to the exotic beast. It shouldn’t have been able to return after escaping.

“Oh right, professor, there’s also this.”At this moment, the assistant seemed to have thought of something as he handed Mario a black chip.

Mario took the chip and frowned slightly. “What’s This?”

The assistant continued, “This was brought back by the exotic beast.”

Mario looked at the expression in the chip’s eyes. After a moment, he continued, “Pass this to doctor William.”

“Alright.”The assistant took the chip from Mario’s hands and walked towards Doctor William’s office.

Mario stayed where he was and observed the exotic beasts that had returned.

He had a nagging feeling that there was something different about the exotic beasts, but he couldn’t tell what it was.
