Because he is moving to the clan no one will take care of his pets for his behalf since he is an orphan and it would be difficult to transport all of the if he decided to take them with him, so the best decision is to release them
i just thought they would allow him to bring them all, especially when they saw what he is raising as to show what he is capable of and mixing the different kind of breeds
Maybe we would see his pets in the future when they've all grown and protecting him from other cultivators with evil intentions (๑•ㅂ•)و✧
i hope his pets wont turn into women! making it more women to his harem if it becomes one
my thought as well which pretty sure would be more interesting than the current flow of the story
why did he let got of his other pets? i think it was a waste for him to let them go! whats the point of raising and mixing breed then he release them, plus wasnt he supposed to be the most knowledgeable of all the people?
