Mas transmigrated from Earth to this world and became an apprentice alchemist. This was a very noble status, a brilliant alchemist could command the respect of any major city. Mas was also proud of his own position. But he didn’t expect that his teacher was actually a huge fraudster, who used subpar alchemy products to trick the Royal Capital.

When they came knocking on the door fuming with killing intent, Mas’s teacher Wosk had already run away. While Mas, who was his student, was left behind to deal with this mess.

[Obsidian Gargoyle], [Lightning Naga], [Iron Golem], [Granite Golem], [Puppet Dragon], [Laval Titan]...... One after another legendary alchemy creatures were born in the hands of Mas, and he gradually gained the title of the God of Alchemy!

One day every human on the world suddenly receives a mail claiming to enact the World Salvation Project. Half in doubt Kurosaki Shion, a diligent university student and loner, follows the mail’s instructions, becoming one of a million Demon Kings governing his very own Domain in the new world.

It has many game-elements bolstered by strategical thinking while at the same time providing funny moments and romantic encounters.
