DxD: I know…I'm not the real one,just a cheap copy. but...I'd win - Chapter 51 - 50:Succeeding in convincing Emiya Archer

With a father as strong as the highest heavens themselves, Gravis wasn't required to step into the cold and ruthless world of cultivation. But when Heaven used him in a scheme to get back at his father, Gravis realized that he needed strength to gain true freedom.

As long as he remained his weak self, he would always remain beneath Heaven’s oppression. Only true power brings true freedom. To gain strength, Gravis ventured into the lower worlds to start his cultivation under true life and death tempering.

Only a strong will, which had been forged in striving for every resource available, would allow him to reach the peak. Heaven’s strongest weapon was Lightning of Divine Punishment, and only if he made this weapon his, would he have a chance.

So, to overthrow Heaven,

Lightning Is the Only Way!

Yet, the path to power is painful.

Not everyone reaches the peak.

But Gravis will!

No matter how much pain he feels along the way!

Bai Qingqing, the disciple of the Divine Physician, with goodwill, treats the domineering Prince for blindness, only to render herself at the mercy of him. In the name of practicing medicine, the doctress makes him have spicy cuisine for every meal as revenge. Seeing him frown upon the food, sweat at the pungent dishes, she is merely stoked! Poor Qingqing is no villain material, she ends up having a soft spot for him. Her tender care for the Prince unknowingly reveals her biggest secret-her true identity. After the prince’s eyes are cured, he mobilizes the military with great fanfare to keep her around…

A striking man of mysterious origin and peerless talent, he looks back at the world, in all its entirety, with utter disdain. And yet, in the treacherous and unpredictable ultimate formation of the Boundless Secular World, he guards a breathtaking ancient qin with broken strings, waiting silently for the destined one to arrive!

A boy encounters him, and knows for the first time that the world beneath the Heavens is a fickle place. Not even demons, devils, ghosts and monsters can match the frivolity of human nature!

A slender physique, and jade-like beauty, but the sword that strikes between heaven and earth is not unlike a streaming rainbow!

The vastness of the starry sky, the seven emotions and six desires! Greed, anger and ignorance! The teachings of Buddha will grant you boundless strength!

A sea of blood will come, at the cost of all mortal beings full of honest hope!

The ghosts wail as the gods roar, but the sea of blood has no end!

Where, pray tell, is the path I should take?

Since there is no path, no matter how bitter and bloody the sea, even if my boat is made out of bones, I will soar to the heavens above!
