In the midair battlefield, Gai Huang overpowered Shen Tianzhan and Wu Yong, who were both Holiness of Nirvanas, all on his own.
Gai Huang was of immense renown, and he was an exceptional figure among the Holiness of Nirvanas found in the realm. He was deemed a truly terrifying figure, as he was lauded as one who stood at the pinnacle of the final plane of sainthood. He was so immensely powerful that he would be able to reign supreme in any realm found within the Crimson Dragon Region.
However, due to the debt he owed to the Ninth Servant, he spent most of his time training in Ancient Imperial City instead and was considered a member of the city by all in Crimson Dragon Realm.
He held Xing Kai in extremely high regard, hoping that he would be able to continue Emperor Zhan's legacy and make it into Renhuang Plane.
Even though Xing Kai was not someone he taught personally, he watched the younger man grow.
