This is why all those who challenged Heaven throughout the ages ended in failure.
In the world of the treacherous Heaven, defeating him is immensely difficult.
No matter how exceptional and unparalleled throughout history, you ultimately can't escape the palm of the treacherous Heaven.
But the idea of the Fire Tribe is simply against the Heavenly Dao.
They wish to create a world of their own.
Just like Xu Zimei's Divine Continent, existing independently, completely free from the control of the treacherous Heaven.
Within the Divine Continent, the treacherous Heaven has no means, for there, Xu Zimei is the god of creation.
The Fire Tribe likely shares this idea.
However, they chose a path even more unrealistic.
Creating a world requires countless powers, and they want to transform it with fire spirits.
The difficulty here is imaginable.
So ultimately, they failed, and the Four Symbols Fire Ancestor used the Divine Gate to seal this heaven and earth.
