Xuetuanzi indeed had a grudge in its heart. It couldn't lash out at Mo Yan, so the farm animals ended up suffering its bullying instead, to the point where they didn't even want to eat the delicious tender grass but just wanted to break through the barrier and ram into the tree opposite to end themselves.
Mo Yan entered the Space, and the little guy sensed her presence. It also heard the shouting but simply refused to respond, determined to give Mo Yan a memorable lesson.
When Mo Yan came looking, all she saw were dense herds of herbivores. Hundreds of animals gathered together, searching for the small Xuetuanzi that was only the size of a palm, a task as difficult as finding a needle in a haystack.
Of course, it would be difficult to find with just two eyes and legs, but with the contract in place, Mo Yan easily found Xuetuanzi hidden on the back of a wild goat.
