ye mei is not a villain, in her point of view ye mei is just a loyal person/supporter to her creator but to archive that she used despicable methods.but lucky enough she found her master. Her making of weapons is to use them when needed and have to be needed by her to archive her goal…by the deal with white demon and qi wiji. well qi suji brother is the one using the face of qi wuji…in the end the plot was amazing it gave me literal goosebumps…it is definitely worth watching especially Zhang Linghe’s fantastic acting.
