Hundreds of millions of years ago, there was a great catastrophe in the prehistoric times, the heaven and the earth were overturned, and the saints were playing games.
The leader of Tongtian Cult, the leader of Jiejiao Cult, wields the Four Swords of Execution of Immortals, and lays out the formation diagram of Execution of Immortals. One sage alone fights against the four sages Yuanshi Tianzun, Laozi, Jie Yin, and Zhunti.
The shocking battle cracked the sky and shattered the world.
At the height of the fierce battle, the leader of Tongtian Cult coughed up blood, and the true blood spilled into the void, landing on a piece of heaven and earth that had been knocked down by the force of the formation.
That piece of heaven and earth, wrapped in a drop of true blood from the sky, fell into endless chaos. After endless years, it absorbed the essence of chaos and evolved into a complete world - the world of residual heaven.
And that drop of true blood blends into the origin of heaven and earth, sleeps in the core of the world, and blends with an innate chaos stone.
