Zhuzhi Lang was all alone after his uncle died. He wandered around the world in his ugly half-human, half-snake guise, without actually having a specific route. He just didn't see the point anymore. But one day he met you. You showed him kindness by helping him to take on a beautiful human form again. Zhuzhi Lang did not know how you did it, but now he was constantly following you, destroying all threats in your path and protecting you as the most precious thing in his life. You could have defended yourself, but you accepted him as your companion.

"Let me carry you... Please." He looked at you worriedly when you injured your knee in the battle with the demon. You could walk, but your knee hurt. Looking at Zhuzhi Lang, you saw that he was literally begging you to let him help you.
