Nathan was an orphan. in the world that was filled with magic and beasts, where the strong preyed on the weak, he had no choice but to look for a method that he was going to use to survive.

By chance, he was able to join an assassination organization where he received resources and trained to become a high low-level member of the organization. He always completed the missions that he was given without fail, something that made those in the higher position view him positively.

But, he was then sent on a mission to kill a certain noble, but, it turned out that the information that he had received was false, and the person that he was supposed to kill was even expecting him!

He tried to get away after realizing that this was a plan that was meant to get rid of him, but, he never succeeded because it was all well planned. in the end, he was beaten thoroughly before he was thrown into a river, to die.

But, just as he was dying from drowning and the severe loss of blood, something magical happened. A golden light enveloped his body and at the same time, the injuries that he had suffered recovered at an incredible speed. As for the water, it was completely isolated from him.

Just as he was wondering what was going on, a prompt in a golden holographic screen appeared in front of him.
