Jun Wu Xie couldn't help but think of Elder Luo's 'hobby' - the art of witchcraft.
In her previous life, Jun Wu Xie had heard of certain ethnic groups in certain places, which were proficient at using this sort of strange and magical art. At that time, Jun Wu Xie was kept in a cage all day, and all she could do daily was to read books, thus having read several books on this subject.
Those books, however, only described the weirdness of this particular subject, but the basis and principle of it was not explained.
Jun Wu Xie remembered that when she was a little old, that demon had also whispered and mumbled about the magic of witchcraft in private, and he had even wanted to uncover the mystery in it, but the result was a failure. At that time, that person brought home among other things, many of these creatures with very strong toxicity.
Seeing everything in Elder Luo's house, Jun Wu Xie just knew exactly what the uses were for those things.
