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.

On the Great Land of China, forces clashed for the sake of supremacy and Bloodline Warriors ran amok; the conflict of the strong threatened to shatter heaven and earth. A young man named Lu Li—nothing more than a humble Coffin Carrier from the Northern Desert—came along with Lu Ling, his sister. The two were regarded as puny insects and bullied, but little did people know that Lu Li had the strongest Bloodline of them all in him.

He mounted the most handsome of horses and drank the strongest of wines;

He bedded the most beautiful of ladies and murdered the most hated of people;

He told a huge lie and carried with him an ill-reputation undeserved;

He traveled all by his lonesome and danced with devils;

He had given his word that he would come back, that he would be strong.

And it was because of this that she was still waiting in the city—alone.
