Thousands of years ago, Rong Yu, the demon lord of the demon world who was driven into the deepest part of the earth, returned to the three realms. On the Changbai Stone on the coast of the South China Sea, he carved the unique python totem of the demon world. Under the black mist, an immortal-eating sword stood on the Changbai Stone for three days, scaring the younger immortals that they did not dare to walk there, causing the immortals to panic.
What shocked the immortal world even more was that the demon king's words that he should marry Xuantian Fengjiu spread throughout the three realms. It is said that on the third day after he returned to the Three Realms, the monsters crossed the immortal barrier between the Three Realms and the Demon Realm in a mighty manner, stepped across the vast Yingshui River, and under the Immortal Gate of the Southern Wilderness, they used the four ferocious beasts as matchmakers and the Immortal-Eating Sword as a gift to marry Xuantian Fengjiu of the Phoenix God Clan.
Originally, there were no two families of immortals and monsters, and it was impossible for the demon world and the immortal world to form a union. Moreover, this Feng Jiu was not an ordinary immortal. Tianzun created the world, the most noble Xuantian clan of the Phoenix clan of the four ancient mythical beasts. There are only nine phoenixes left in Xuantian's clan. All eight are majestic phoenixes, but she is the only one who stands out. From time to time, immortal friends visit Nanhuang, ostensibly to see old friends and full of Feng Jiu's ideas. Perhaps due to the prying eyes and harassment of the various immortals, Feng Jiu had already made a marriage contract with Shenwu Yukun, the eldest son of the Shenwu clan of the same ancient mythical white tiger clan, and was able to block many male immortals who were about to make a move.
Rong Yu's previous behavior at Changbai Stone had angered all the immortals, and this time he was accused of stealing someone's wife. In order to save face, the White Tiger clan used all their strength to fight against the demon king and ensure peace in the three realms.
The strange thing lies in the ending of this decisive battle. There is only a thin page of records in the Four Wilderness Scriptures. The ferocious beasts caused chaos and the demon world was in chaos. The four great beasts and the demon king fought for three days and three nights in the wilds of Hanzhou, and the demon king Rong Yu died. But there was no explanation as to why all the demons disappeared without a trace overnight after that battle. There has been no news for ten thousand years. Wu Yukun and Feng Jiu, the white tiger gods of the Protoss, are also missing. Everyone speculates that the couple has been living in seclusion for ten thousand years. However, there is only one person in this world who knows the whole story. This person is Shenwu Yan, the biological brother of Shenwu Yukun, the White Tiger God who died thousands of years ago and his body disappeared from the three realms.
