Daming: Grandpa Emperor, please get up and sit on my throne!

The Taoist celebrities and alchemy masters sitting here are not ordinary people to the outside world, and their understanding and knowledge of many things are naturally extraordinary.

Zhu Yunhuan nodded and continued, "The actual reason is actually the difference in composition. It lies in the iron content, carbon content, and various impurities in the final product. Products without impurities and with a low carbon content will eventually exhibit the external properties of steel."

Zhu Yunhuan came to this conclusion.

Someone immediately responded, "Elements. His Majesty once said that most things in our daily lives are a mixture of various elements. Just like the ground we walk on, it contains oxygen, silicon, aluminum, iron... and many other elements. The same is true for iron ore before it is melted. Even after it melts into liquid iron, these elements still exist and will not disappear."

After he said this, Zhang Yuqing, who was sitting in the front row, stroked his beard.

As if he had thought of something.

His eyes suddenly lit up as he spoke, "According to what Your Majesty said... if we could find a way to remove these impurities through some chemical reaction and lower the carbon content, we could create steel without relying on luck! Then, wouldn't it be easy to create a famous weapon that's incredibly sharp and resistant to rust?"

"Tsk, I just don't know the main elements in the iron ore."

"Yes, once we know the elements, we can think about how to remove them."

"..."

There was a burst of heated discussion in the classroom.

Zhu Yunhuan taught them some basic chemical knowledge, intending to be a spark and let the fire spread freely in this era. Naturally, he would not prohibit such voices in the classroom. He just sat on the podium with a calm expression and let the people below talk.

In other words, isn't this lively class right now the result of the fire that has spread throughout this era following his spark?

They already had a preliminary understanding of concepts such as chemistry, elements, etc., and had a certain understanding of various redox reactions. Zhu Yunhuan only mentioned the composition of steel, and they were able to think about the rest of the story on their own.

Even the direction is right.

The converter steelmaking method is to remove impurities and reduce carbon through various reactions!

However, Qin Kui, the "auditor" dressed in a crimson official robe, was completely dumbfounded. "So you all understand? Only I don't understand?"

What kind of chemical reaction is this? What the hell is going on? Both His Majesty on the stage and the "Daoist priests" below were speaking human language, but he didn't understand a single word!

I was staring at every word His Majesty said on the stage, my mind was still in a mess, I couldn't understand it at all, and then these people started chattering...

At this moment, Qin Kui felt like a thousand alpaca horses were galloping through his heart.

At the same time, he keenly grasped the key point from the noisy discussions: "Didn't that highly respected Taoist Master Zhang of the Zhengyi Sect just say... that one doesn't rely on luck to cultivate strength?"

Qin Kui's lower eyelids twitched slightly, and he nodded. He was very sure that he had heard correctly: stable steelmaking! The guy even followed it up with a sentence: making sharp swords that are not easy to rust, it's easy!

It would be fine if only one person said this.

But he listened carefully.

The other people present, including Taoist Master Ma from Quanzhen Sect, Taoist Master Liu Yuanran who was rumored to be the best at alchemy... and so on, all discussed the matter on the premise that they agreed with his point of view!

Even if Qin Kui doesn't understand chemistry.

But being here, it is still possible to discern the attitude and atmosphere.

"in other words."

"The so-called 'mass steelmaking' mentioned earlier, at least in the eyes of this group, won't present any major technical difficulties!"

Qin Kui's heart began to beat wildly. He came to this conclusion secretly in his mind, and his hands began to tremble with excitement.
