How can iron ore be smelted into steel in one go? Let’s talk about the history of steelmaking.

The Tang Dynasty’s army? Where did you hear that? It's not a steel knife, it's a stainless steel knife. Haha, just kidding. I'll introduce you to the history of steelmaking in detail when I have time. Now I'm going to make iron!
