Actually there are three Li Shuangxing in the game. First, Xiao Jiang once said that Li Deshan published a paper under the pseudonym of Li Shuangxing at the beginning of last century. Secondly, from Zhao's suicide note, we can know that Li Deshan and a 10-year-old child became very irritable after changing their brains, and we also know that Li Shuangxing in group chat is also irritable, and the key is to speak Japanese, so we can conclude that Li Shuangxing's new name after changing his brain is Li Shuangxing.

The third is the time when Li Deshan first changed his name. From Xiaojiangkou, we can know that the year is 1970. Later we can know from Du Siyuan's diary that after Li Shuangxing committed suicide, the curator adopted a new Li Shuangxing. Obviously, this Li Shuangxing's brain still belongs to Li Deshan.

The timeline of the game is like this: white cat, silent mansion, baby broken, and then darkness is an independent plot. If I recommend how to play, I personally think we can experience the silent mansion first, and then the white cat will break at last. But I see that the official setting of Baby Destroyer is a novice book, and it is ok to play according to the official. Anyway, the game feature of this game is flashback. I feel that the official design of this game is to make players want to know who Li Liangping is and then play below.
