Nantian Hao was born in the Nantian Clan close to the end of the Difficult Dao Era. He was quite talented and was a renowned genius with many great contributions. Thanks to it he became the Regional Monarch of the Southern Heavenly Kingdom.
At some point he met Li Shuangyan and was infatuated with her. He even came to the Nine Saint Demon Gate to propose, but Demon King Lun Ri used the excuse that Li Shuangyan was the descendant of the Gate to refuse him.
Nantian Hao then noticed Li Qiye standing closely to Li Shuangyan, and grew immensely jealous. He tried to interrogate Li Qiye, only to be completely ignored by him. Some of the clansmen berated Li Qiye, but were beaten up by Li Shuangyan, while Li Qiye reminded them to be less arrogant, because Southern Heavenly Kingdom isn't really an Imperial Lineage and have no right to act all high and mighty.
Nantian Hao set off in pursuit and eventually tracked mysterious frog to the lair that was carefully prepared for it by Li Qiye. Li Qiye had searched in vain for this frog all around the Nine Worlds for millions of years. Now, that he finally found it, he was afraid that frog would escape again, so he demanded Nantian Hao to leave immediately. Nantian Hao refused to leave and sent his people to kill Li Qiye, while he himself had tried to capture the sleeping frog. Unfortunately, the frog sensed the danger and escaped again.
