When Yu Ren left the B72 Highlands, he received a promise from Ji Xinghe.
"Once there are five hundred mechas like yours in active service, I will apply to transfer you to the Xinghe Squad."
"What about my code name?"
"It's self-declared."
"How about Fool? The fool of the fools, and the human of the superhumans."
"That works."
"Thanks, then. I'd better leave now. Well... Colonel Ji Xinghe, I'm sorry."
After apologizing again, Yu Ren decisively ended the communication, using deep breaths to calm his emotions.
The audacity required for him to elicit an apology from Ji Xinghe instigated an internal emotional upheaval that outsiders could hardly fathom.
Fortunately, Ji Xinghe didn't take him to task, the conversation had been rather pleasant.
Deploy 500 units?
Yu Ren was filled with anticipation and motivation. He knew that the speed of the deployment of the new mechas and his efforts were correlated.
