The Backbender (Avatar: The Last Airbender) - Chapter 24 - : Acceptance.

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts. However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew. Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack. There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree. “Let the war begin.”

Yu Qiu once thought that he could rely on his shixiong forever, but when he was captured by the Shadow Demon, he watched helplessly as his shixiong stepped into the bride room together with a woman.

He knew he was one foot in the grave, powerless to reverse the situation.

After reincarnating, how could he walk the path of seal cultivation again?

Rebel? Vengeance? Revenge? Depend on a loyal dog who would be his shield?

That was too low for him!!!

He was going to:

Break up that haze in front of his eyes and turn it into tall mountains.

No longer depend on anyone, but rely on his own strength for everything.

Make every cultivator never say the words “seal cultivation is only supplementary” ever again.

Become the strongest person in the world.

Show that he will become a Daozhang.
