Iron Witch Wants to Change the World

Reincarnated as the Iron Witch, Euler looked at the world like garbage. Stupid humans are obviously the weakest species and have very little magic power. Why do they still devote their whole life to magic that is impossible to achieve outstanding achievements? Believe in steel and technology, and bow down to the great, noble, beautiful, and perfect Steel Witch. I will give you technology and knowledge to bring you a better life. In the 35th year of the Iron Witch calendar, humans have ascended to the throne of the third race. Feeling the huge crisis, the dragons, elves, dwarves, demons... Launched a joint war against humans. Euler held up the wand that symbolized technology and steel authority, and roared across the battlefield: "Launch the final offensive!" Humanity has received support from the Steam Knight Legion! Humanity has received support from the Iron Blade Legion! Humanity gets support from strike cruisers! Humanity has received the support of iron-blooded ambition! Humanity has received support from the magic armor group! … The big bell rings once! Push the lever to activate the piston and pump! The big bell rings twice! Press the button and start the engine! The big bell rings three times! Sing in unison to praise Euler! "Infinite supply of resources, reinforcements are on the way, humans, in the name of my Euler, defeat all enemies!"
