What the f was that ending????

COME ONNNN did he seriously just turn back time?? I mean how did that do anything since everything will just happen as it did again?? Couldn't he just have turned back time so the blood would flow back into him and he'll be fine again??

Oh my goodness that half-assed ending pissed me off .. 

Also I hold that both cat demon bro and og Wang bro love Tao bro
