Perhaps it was because the voice of the fifth ancestor of the Mind Control Sect was too full of admiration for his father, and it was quite different from the usual way of addressing his father in the Dongyuan Continent, so it left a deep impression on the several Quasi-Immortals of Nirvana Building.
In addition, Zhu Wanhao was vaguely regarded as the ancestor of the ancestors by the entire Control Heart Sect. He was above the few ancestors and was treated like a parent. Therefore, the nickname of Control Heart Dad came out.
This nickname obviously couldn't describe Zhu Wuyang's strength. After all, several Dacheng Quasi-Immortals of Nirvana Tower had never seen the scene of the two sides fighting. However, it was enough to show the strength of Zhu Wuyang. To be precise, it should be the strength of the controlling father.
