Chương 451: It's A Key Invention!

"What happened? Who did this to you?" Baiyi hurried to Anna and reached out to pat her head, but she ducked and hid behind Nota. Anna peeked out from behind Nota, looking at Baiyi in fury. 

"Hey, hey, what's the matter? Someone bullied you, didn't they? Well, tell me who its and lemme at' em!" Baiyi gallantly said.

Nota sighed. She took the jet-black rock from Anna, raised it to Baiyi's face and pulled out a tag that was stuck to it. "Mentor, do you remember that it was I who brought you this ore? I brought it back from my last excursion to be appraised. Shouldn't it be staying put in your lab?"

"…Oh. Ohh." Baiyi froze. He had just remembered that the black rock was the first thing he threw into the scribble. 

"I knew it! You… B-big Meanie!" Anna whispered from her spot behind Nota's back, her eyes narrowing with distrust.
