I don't understand the mc at least in connection with the villain tag I would understand if he later wants to use it as a yin cauldron but otherwise the action is stupid, if it becomes as strong as the mc it's useful in the fight for just as strong but also very difficult to control, when she is stronger she is impossible to control and a great danger and when weaker than the mc she is useless.
I don't think it's bad he's worried or that being a puppet of power, at least at this early stage, because xiao yan is a possible enemy of his and a big factor in his death (or it may not be and there are other cases much more dangerous , but it's good to be cautious) and with that seek to get a little luckier, and cut some paths/moments of luck/power from xiao yan is a logical development of a step to be taken, and also directly and indirectly sponsors and moments of xiao yan's power is involved with women, so hardly the mc would run away from being also directly and indirectly involved with these women. so for me, this initial mentality is good, of course later it's something else, which should be observed. it would be good for him to form a relationship with gu xun er, and with the dragon girl as well. the story looks very interesting and very nice.
