The Revival of the Demon Clan from Scratch

In this magical world called [Gaxiu Continent], there are physically strong [Demons], [Humans] who rely on wisdom to make magic weapons, [Elves] who are proficient in elemental power, and [Vampires] who master terrifying spells! Relying on their own unique advantages, these four major races have been at war for thousands of years! An Quan, an ordinary high school student with a serious academic bias, suddenly traveled here while taking a nap in math class and transformed into the supreme marshal of the demon clan! However, at the beginning of the time travel, he was confused, but what he had to face was the destruction of the [Demon Race]! And if you want to return to the original world, you must help the demon princess Loli regain her position as the demon emperor! There are no soldiers or generals in hand, and you have to face pursuit from all directions at any time! In order to return home, An Quan had to embark on the hellishly difficult road of demon revival from scratch!
