Lei Zhenzi, the adopted son Ji Chang met on his way to Chaoge, had grown into a boy with strong martial arts skills. Yun Zhongzi figured out that Ji Chang was in trouble at this moment, and planned to send Lei Zhenzi down the mountain to rescue him. Lei Zhenzi was ordered by his master to search for weapons that fit his hand. He couldn't find the weapons but found delicious apricots. He swallowed them greedily and turned into a strange man with yellow hair, blue face and wings on his back. When Yun Zhongzi saw this, he put his hands on his hands and smiled, and ordered him to fly quickly to save his father.
