Traveling through the ancient times, Cang Xuan became a hollow willow tree in Kunlun Mountain, accompanied by the [Dao Compass], which can deduce martial arts, calculate the secrets of heaven, and understand cause and effect.

He knew very well that the world was vast and that all people below the level of saints were ants.

During the first catastrophe of Longhan, he was in seclusion; during the war between wizards and demons, he was planting trees; during the catastrophe of Conferred Gods, he was still deducing his own path in the cave.

He never takes the initiative to get involved in cause and effect. He always plans everything carefully before taking action. With his endless lifespan and patience, he silently makes plans.

Billions of years later, when the saints thought they had control over the world, they looked back and found that the willow tree rooted in Kunlun had already unknowingly covered the entire sky of the ancient world.
