The ultimate plot twist would be that Huanyu' mom is the leader of wufeng.they wanted to take over Gong mountain without shedding blood by making Huanyu the next sword wielder.but after ziyu was born ,they found out that the father is favouring him .they were afraid that he will ruin their plan so they sent assassins to kill ziyu .the assassins however killed shangjue's brother and mother by mistake,because the kids were the same age.after that Gongs tightened the security of the mountain so they couldn't make a move again.they made another plan and executed their plan as soon as the brides entered the mountain.
Why does this fit so much lmao. We haven't seen HuanYu's mom yet, but it might be the case. WuMing is definitely someone that does not knows about the back hill, or so I think. If WuMing knew, why not send this info with the info on bride selection? Two birds with one stone that way.
