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.

Fate is a funny thing.

“The more the Church supports me, the more it proves I have done the right thing. The more the heretics oppose me, the more it proves I have done the right thing.” “Even when heretics praise me, it further proves I’m right. If heretics stay silent, it shows I have done impeccably!” “If the Church opposes me, it means they have all fallen into evil heresy, and the more heretics oppose me, the more it proves I have done the right thing.” In the year 681, An Su was crowned the youngest Pope in the history of the Church. During his speech, he provided important guidance for the forthcoming de-divination work, emphasizing: “Now that both the Church and the heretics oppose me, it precisely shows I am on an exceedingly correct path!” ... The year 685. “It is not that the Evil God cannot be summoned, but that choosing him to take the stage is more cost-effective.” Such was the assessment of the former holy woman of the demons, Yage Silvia. This statement, once made, instantly attracted attention from all sectors of society—the extensive documentary “The Legend of Pope An Su” continues to broadcast for you.
