crazy theory of mine: Su Han's mother got through tribulations and turned into a heavenly dragon, her father failed and stayed hidden in Dragon God Shrine and vowed to never show himself again until a special condition is fulfilled đ¤
f*ck Ren.. so he know they have to go but still didn't care for them.. even after all they have done to him.. without them he would long dead and his immortal body that grant fast cultivation is also from them... he really isn't worthy of Lu sisters...
It would be very nice of Ren if could consumate with the twins as a parting gifts to them as a reward for helping him get through all those troubles before..
