Comments of chapter undefined of Douluo Dalu: The Rise of Pokémon

I just read a Douluo Dalu 3 Fanfic over 400 chapters and I like it a lot. It is very amusing, though I want to ask something. In that fanfic I was reading, Tang Wulin got gender bend and turn into girl. So Im curious, do you think there should be gender bender? Because this is my fanfic, and if I want to, it can make sense, since 10,000 years ago which is Douluo Dalu 2, Wang Shòu change the story a lot, so it doesn't seem extreme that it cause a gender bender in Douluo Dalu 3. So what do you think?
