This time, Ji Ningyan just wanted to bring order to the chaos and get all the plots back on track. Under his violent suppression, those evil spirits were finally going to join the plot with the protagonist, but at this time, the protagonist went crazy. Mo Yun collapsed and became angry: Senior brother, who am I to you? Ji Ning thought for a while and replied sonorously: Son! One sentence introduction: He changed the world, and the world changed him!
