It's nice to hear the vivid voice of Rookies, who has returned after a long time. I'm studying Rookies's lecture again, and since you gave me a lecture on a real-life project, I'm gaining a lot of insight into my studies. It won't be easy to analyze the code, but it's similar to the design structure I learned from MMORPGs, so I'll take a closer look. Stay healthy and have a prosperous business~
