He was reincarnated and became a demon with extraordinary talents and a long life span.
Although he became an orphan with living parents at birth, he had to fend for himself and be careful of his own people and humans, but it didn't matter. At least he suddenly had a system when he was three years old, but the system was unexpectedly not very useful.
But it still made him go back to the past, made friends with Fulilian, and became the junior of the ancestor of human magic, but he soon discovered that this friend had a big prejudice against the demons.
It's okay, fortunately, the little sister of the tribe who I knew since birth-Aura has become successful, but... when I was a child, I often ordered her around, so the relationship is a little subtle.
The problem is not big, he also knows the strongest hero, but... the other party died a little early.
Just jumping back and forth between humans and demons, he gradually found that it seems that there is no side that can be relied on.
"There is no way, I still rely on myself."
He set a new life goal for himself-kill the current demon king! Become the new demon king-tentative.

他转生了，还成为了天赋异禀，寿命悠长的魔族。虽然一出生就成为父母健在的孤儿，一切都得自食其力，得小心同族也得小心人类，但没有关系，至少他三岁突然有了个系统，只是系统出乎意料不太好用。可还是令他回到了过去，结交了好友芙莉莲，成为人类魔法之祖的师弟，但他很快就发现这好友对魔族有不小成见。没事，好在出生就认识的发小族妹——阿乌拉已经出人头地，只是....小时候自己经常使唤她关系有那么一点微妙。问题也不大，他还认识了最强勇者，不过....对方死的有点早了。就这么在人类与魔族之间反复横跳，他逐渐发现好像就没那边能靠得住。“没有办法，还是靠自己吧。”他为自己设置了新的人生目标——干掉现任魔王！成为新的魔王——暂定。
