Han Sen had been working for four days and five nights. By this point, he had almost exhausted all of his power. Thus, he had to bring it all to a close.
It was not like Han Sen wanted to rest. It was just that the sheep's jade body was just very weird. If Han Sen's power came loose, the structure of the sheep's jade body would recover in a short amount of time. So, Han Sen had to keep on going. Otherwise, all of his progress would have been for naught.
It was easy to tell Han Sen had been working too hard. He was becoming skinnier. His eyes were turning red, and his eye sockets were sinking deeper into him.
White King and Bottle Fairy felt quite touched. They did not think Han Sen was going to put so much effort into doing this. He was not afraid they would attack him. It gave them a better impression of Han Sen's character.
