Tainted will - Chapter 69 Mystic Realm, The Tier-8 Violet Stellar Grass.

What are you going to do when you pass through another world?

Yalin(MC): Perhaps, many of those seniors who passed through another world would like to use violence to solve their problems, but I like to control the fate of a country with economics and races with faith, I use benefits to instigate others so that I profit, and even making them take risk for me without them even knowing. In each country the highest is the king and behind the king is a string that is attach to my hand, for I am their puppeteer.

Yalin(MC): Certainly the credit does not only belong to me, I must give my thanks to the great knights and their leader Zero(Code Geass). The supreme master of blood, the moon princess(Tsukihime), the black and white princess, and also my ‘good friend’ called by his title the ‘God’s left eye’, president of the neutral autonomous city. Finally I must give thanks to my loyal and competent subordinates!

If you don’t know anything, you might think Blake had a perfect life. Good-looking face that made everyone turn their heads, an athletic physique, photographic memory and a good head that let him ace all of his exams, and also a kind heart to prop it all up.

But you couldn’t be more wrong as in a world where even a three-year-old kid could use mana, Blake was one of the unfortunate ones who couldn’t utilize the magical power that enabled humans to break past their limits and defeat the powerful demons that used nether instead of mana to cast their own demonic spells.

Looks of disdain, mockeries, and even straight-up bullying were not an uncommon occurrence for him as he had to deal with them every single day.

One day, the bullies went too far and almost killed him. The pent-up rage and hatred in his heart peaked up as he remembered the faces of his bullies that had beaten him half to death.

He thought he would finally die when his head was suddenly struck by a severe headache and his eyes went dark.

But never did he expect when he regained his consciousness he would find a pair of horns on his forehead, sharp claws on the tip of his fingers, and jet black skin covering his body from head to toe.

Follow Blake’s journey as he became the master of the nether and demonic spells, climbing the ranks of the demon realm as he gathered his own demon followers, and finding out the real truth veiled in his home world while creating legends for himself both in the demon world and in the world where he came from.

The King Of Assassins was a monster that reigned over the world of hitmen for long years. He was the absolute peak that no other being could reach. His name reached the ears of every powerhouse in the world and sent shivers through every human.

Yet, his legend came to an end suddenly when he died in unknown circumstances.

However, instead of disappearing forever, he was given another chance in another world by the goddess of reincarnation. It was the world of an old book that he read back in the time. A world where everything was possible, where humans could reach new heights that were impossible in his old life.

But, this place didn't seem to be normal as it carried a huge surprise that will make his journey seem all the more interesting.

The Goddess of reincarnation wasn't as holy as anyone would think. She was nothing but a twisted being who found a toy to play with. The goddess manipulated the world that he was going to and changed all the heroines into these twisted beings that fit her character. They were all now harboring this unhealthy obsession toward him and trying with all their powers to take him away for themselves.

Nikola Tesla, the genius, a man who lost everything to balant capitalism and betrayal, awakens to find himself reborn as an orphan. What is this world? Why is he here? And will he once again fall for the capitalistic betrayal or pave his own way? What would happen if his genius adapts to cunningness of the society?
