Me, the Girl from Another World and the Savior

In an accident, Deaver was drawn into a whirlpool of light and shadow. When he opened his eyes, he was already in a strange world. There are magical cities with towering towers, as well as huge battleships driven by steam and gears; there are mages who recite spells, and craftsmen who control mechanical puppets. However, this continent is on the verge of destruction - the ancient demon king has awakened, leading a twisted demon army to devour the kingdom of humans and elves. There are many suspicions among the countries, the power of technology and magic are in conflict with each other, and the world is heading towards collapse. Lin Lan unexpectedly acquired the strange ability to combine "magic formulas" and "mechanical principles", becoming the only person who can connect the two powers. During the adventure with his partners, he grew from an ignorant outsider to a being who can change the situation: fighting side by side with swordsmen, princesses, and dragons, cracking the lost ancient mechanism, and awakening the dormant holy artifact. In the end, he will face the shadow of the Demon King that symbolizes despair - with the intertwining of technology and magic, he will write the ultimate battle to save the world.
