Laying Low in a Chaotic Demon-Warrior World, I Subdue Evil and Become a Saint

Fang Xuan, the sharpest hidden blade of the Immortal Realm's council, commands a hundred death warriors and specializes in jobs that must never see the light of day.

After returning from a bloody battle, a cold voice rang out in his sea of consciousness: [The Solo Gate Between Two Realms has been activated.]

From then on, he traveled between the two realms, quietly building up his strength in the shadows.

The Immortal Realm ordered him to purge a demon lair, so he turned around and stepped into another world of dragons and magic. Seven days later, the mission was "unexpectedly" complete.

The council marveled at his efficiency, unaware that his sleeves concealed dragon crystals, his pills were mixed with unicorn powder, and his life-bound magic treasure had dwarven divine steel forged into it.

Until the blood moon shone over the Immortal Realm and the other world at the same time, and the abyss tore the latter apart. Calamity erupted in both realms at once, and the council declared the Xuan Battalion expendable.

Fang Xuan calmly accepted his final military order and returned alone to the secret chamber between the two realms, the only one he could open.

The System's display before his eyes was filled to the brim, and lines of cold, mechanical text appeared:

[The origins of both realms have finished fusing.]

[Immortal Martial Dragon Abyss Sacred Physique: ready.]

[Alliance of Ten Thousand Dragons: responding.]

[Red Abyss War Soul: awakened.]

As the flood of destruction was about to swallow the borders of both realms,

he alone stepped into the heart of chaos.

With his left hand, he unfurled an Immortal Dao battle formation. With his right, he raised the laws of dragon speech.

Behind him, the phantom forms of two hundred loyal souls roared. In the skies, the projections of ten thousand dragons answered the summons and came to pay homage.

"Once, I fought at another's command, just to grasp a sliver of hope for survival."

He took hold of the new Dao Seed, fused from the laws of both realms. Its light burst forth, illuminating two worlds on the brink of collapse.

"But now..."

"I shall become a Saint and reshape the cosmos!"

This is the story of a commander who walked through desperate straits, gathering strength in the shadows between two realms, until at last he shattered everything with a single punch...
