The Poison Flood Dragon Clan was a mighty power in the Demon Realm. Without the Dragon Race and Human Race to hold it in check, its overall strength far surpassed that of the Yangtze Flood Dragon Clan.
After Fang Yun had all but wiped out the Yangtze Flood Dragon Clan in one fell swoop, the Poison Flood Dragon Clan had become the only sizable Flood Dragon Race population in the Myriad Worlds.
Since the Poison Flood Dragon Sage and the Flood Dragon Sage were on good terms, the Poison Flood Dragon Clan had been itching to march against the Human Race ever since Fang Yun occupied the Flood Dragon Sage Palace. Fang Yun had become a thorn in their eyes and a splinter in their flesh. All the flood dragons who had escaped gathered among the Poison Flood Dragon Clan, proclaiming Fang Yun's wickedness every day, hoping to borrow troops from the clan to avenge their dead.
Recalling the Hall of All Sages' intelligence on the Poison Flood Dragon Clan, Fang Yun recognized this Fifth Realm Great Flood Dragon King as King Jiao Yan. Having once swallowed a peculiar divine stone, he could nurture a powerful fiery poison within his body, making him far more troublesome than an ordinary poison flood dragon. Once he advanced to the Emperor Realm, he would be able to rival the peak emperors of every race.
However, Fang Yun did not take King Jiao Yan seriously. The Flood Dragon Race's true strongest emperor was named Jiao Bone Emperor, and he was even more extraordinary. He actually had two spines, and his body was half again as broad as a poison flood dragon of the same level, granting him boundless strength. He had once sparred with the Demon Emperor for a long time before finally losing.
