Pay Attention, the Man in Front of You Is Called Xiaoshuai

Pay attention, the man in front of you is standing upside down with his head in the toilet just because he got a marketing account to travel through the system. (You can't write byd without a system, right?) What's going on with this line of brackets? It turns out that Xiaoshuai not only obtained the marketing account traversal system, but also obtained the barrage comment system, which allowed him to learn about the barrage in the marketing account's videos.
