The Tree of the Heavens and Worlds is the embodiment of the existing universe, a tree with a thousand branches, a branch with a thousand leaves, with different leaves and leaves, born in chaos and growing in the underworld, the Tree of the Heavens and the Underworld, and the Underworld, together with the authority of the Heavenly Dao.

The trunk of the tree represents the great world of the wilderness, the branches represent the three thousand small worlds, the leaves represent the three thousand small worlds and the subsidiary worlds.

After the death of the creatures of all worlds, the souls return to the underworld, forming a tree of nourishment to nourish the heavens and all worlds, and the fallen leaves return to the roots, thus forming a great cycle of heavenly dao, which is endless.

The way of heaven is unkind, taking all things as dogs, and the top level of the great world of the desolation is unwilling to become ants under the way of heaven, in a vain attempt to usurp the way of heaven, create reincarnation by themselves to prove the mixed element, and jump out of the ten thousand worlds. The great power of the desolation wants to bind the beings of all worlds to their own world and reincarnate in the past life, so as to weaken the authority of the Heavenly Dao of the Tree of the Heavens and the Underworld, and all walks of life will form a small cycle of the Heavenly Dao, and the great power can also control one realm by itself.

The consciousness generated by the underworld is the lord of the underworld, unwilling to be bound by the power of the Heavenly Dao, trapped in the underworld and accompanied by lonely souls all day long, and wants to enter the world to walk, even if he becomes an ordinary person, he is willing.

The Eye of the Heavenly Dao patrols the universe, and the tricks of the Great World of the Great Desolation naturally cannot escape the eyes of the Heavenly Dao. In order to break away from the Heavenly Dao, the Lord of the Underworld controlled the Immortal Qi to cover the eyes of the Heavenly Dao, and cooperated with the top level of the Great World of the Flood Desolation to strip the Underworld from the Tree of the Heavens and Ten Thousand Worlds, so as to achieve his own goal of getting rid of the Heavenly Dao.

However, the power of the Great World of the Great Desolation underestimated the strength of the Heavenly Dao, and did not complete the work, but instead intensified the contradiction between the two lich clans, and the Great War of the Vast World was about to break out.

There is never a winner in war, until the great world is torn apart.

The great world of the desolation was also swallowed by the Heavenly Dao, the aura gradually escaped, the monk's longevity was reduced, there were no more immortals, the saints did not come out, and the great power hibernated in order to survive.

The Heavenly Dao is damaged, and the Heavenly Dao is insufficient, and the Great Cycle of the Heavenly Dao is broken, and the souls of all worlds are reduced to ownerless and lonely souls, wandering in all walks of life.

The Underworld cannot recover the souls of the creatures of all worlds, and therefore cannot nourish the trees of the heavens and all worlds.

The trunk of the Tree of Heavens and Worlds can only absorb the energy of the branches, and the branches can absorb the energy of the leaves, and the leaves can only gradually wither.

The energy flowed in one direction, and the worlds represented by each level also disappeared, and the Tree of Heavens and Worlds gradually withered.

The extinction of the Tree of the Heavens and Worlds is unstoppable, but the number of the Great Yan is fifty, and there are nine out of forty, and the remaining "one" is the glimmer of life.

The Heavenly Dao incarnates as reconstructing the heavens, all worlds, and the underworld, trying to find the "one" that has escaped.

The earth world, originally a small piece of fragment torn by the co-workers of the great world of the flood and the desolation when they touched the mountains of Buzhou (so there are various myths of the flood and famine on the earth, but they have never seen the real thing), fell on the leaves.

Due to the one-way flow of energy, the leaf world has to plunder to the cell world in order to survive.

The protagonist is forced to enter the world of leaves from the world of fragmented earth because of the level of plunder formed by the demise of the Heavenly Dao, and continues to grow in the crisis of the ten thousand worlds.

Is he the "one"?

Everyone can become that "one" for those who fight for the crossing.
