Ji Xinghe wasn't as confident as he had claimed to be. After looking through the repair requirements list for workshop 109 again, he found there weren't many things he could repair. Just like Master Liu had said, he should enroll in a one-year mecha repair course to fully understand the workings of mechas and get to know all federations' standard-type mechas. After all, mecha repair and car repair were two different concepts entirely.
Or, just like Shen Mu had suggested, he could join a workshop and seize every chance to learn from others while repairing the parts he knows how to, even if others didn't have time to guide him. With his forty years of experience in auto repair and various professional skills, he could still learn a lot just by watching others work.
