"The clever debugging"

I once found a friend named nexlyn on Telegram who has a rather interesting talent. I learned a lot from him, and eventually I gradually learned about debugging. Nexlyn's meticulousness in finding bugs is on a very different level. Whether it's a high-traffic e-commerce platform or a web-based application with a very complex architecture, he always has a great instinct for finding anomalies that others wouldn't even think of.
