I Can Pick up Treasures in My Dreams

Generally speaking, it's okay, but after seeing the mermaid use the cognitive-altering treasure on the pig's feet without success when they first met, she suddenly felt that she was short-handed and suddenly became a stallion. In this civilization, it's not considered promiscuous, so just because she's a mermaid, she just falls asleep? Does this have no impact on cognition? If you fell into this kind of scheme and didn't retaliate, you would actually feel that it would be a benefit. At this point, I suddenly couldn't watch anymore.

There are no other problems except that the ending is incomplete and the hole is dug but not buried later.
