Mo Wuji was too lazy to bother with Shuai Guo calling him Master anymore. This bird was still growing so perhaps after a period of time as it interacted with more things and people, Shuai Guo would start to correct himself.
Mo Wuji had no hesitation as he immediately direct the flying ship towards the Universal Hall. With his cultivation level at the True God Stage Level 2 coupled with his Grade 7 Wind Escape Technique, even if he met an expert in the Great Circle of the Worldly Immortal Stage, he would be able to escape easily.
The difference between True God Stage and Worldly Immortal Stage was definitely not as great as the difference between the Nihility God Stage and the True God Stage. Nihility God Stage belonged to the Earth Realm while the True God Stage belonged to the Heaven Realm so the gap between them couldn’t be bridged with any technique.
