There is no such things as u said. 1st time he could defeat LSF, he get help from two expert from Shaolin and…
That part I understand. But before that, XQS beaten by LSF when she saved Tang Fang. XQS supposed to be weaken but he meet again LSF and somehow they are equal. That was before Shaolin and Wudang.
He also constantly beating random goons by himself. If he can do that, why he need deploying trap and whatnot.
I feels like story is kinda all over the place. Xiao Qiu Shui power level is confusing, sometimes he is strong than weak. Sometimes he struggle than he beat some other guy effortlessly. I feels he is not on level of LSF but on the other occasion, he can fight LSF.
He just go weak and strong depends on writer mood or something.
My only complaint is everyone have similar hair style, similar hair bang and lack of diversity. Wuxia is famous for characters with whacky appearance and weirdos.
Watching frist two episodes I really like that ml didn't remember everything he didn't know complete novel in…
Initially the character really overpower and brute force his way to the top. I feels like kinda bs that he just good at everything. Now he is powerless and need all details to solve the problem. But he don't remember it.
