Be careful! Enter! Kidney! Enter! This is the first time I write this. This article is purely about the four-free products (no Tom and Mary, no cp, no h, no morals), which is purely a work of convulsions while waiting for the animation. It just changes a little bit according to the animation. The biggest function is to practice correcting incorrect sentences (science students, please be accommodating) and to recall the green years of primary school in words. The setting will definitely differ from the original work (perhaps significantly).
