Fantasy: Build Iron Man from Scratch!

Ning Yuan: "Jarvis, activate the steel armor." Jarvis: "Sorry, Mr. Ning Yuan, there is no steel armor for you to use at the moment. You need to build it yourself." Ning Yuan: "???" Traveling to a different world, it doesn't matter if there is no system blessing, but you have to build a steel armor yourself! Let's not talk about whether there are materials, wires and reactors here. As a poor little blacksmith, Ning Yuan couldn't afford it even if he had one! Unable to practice, no armor! How should Ning Yuan face the danger from the evil demon! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
