Allen opened his palm and a shining machine core appeared in his hand.
The core of the machine was crystal clear, without any impurities, and it emitted a faint golden light.
"This is!" Everyone gasped.
"This is the boss's heart of machine! A heart of crimson gold level!" Nolan exclaimed. She hadn't seen the gold heart of a machine in the machine city for many years.
Hearing the words "gold-level", Bobby and the others were also excited.
"How, how did you get it?" Nolan reached out her trembling hand, trying to touch the mechanical heart in Allen's hand.
Unlike Nolan, Bobby and others were more concerned.
It was not that easy to deal with the crimson core group. Previously, no one could defeat the mechanical boss with joint efforts, not to mention that Allen was alone. Allen must have paid a heavy price.
Noticing that Nolan's eyes were shining, Allen gave the core of the machine to Demis and chatted with Bobby.
