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

But then Qin Kui felt relieved: Isn't this the character of the young emperor? He sees everything clearly, nothing can escape his eyes.

He has gotten used to it a lot now.

Naturally, he didn't dwell on this matter too much, but immediately focused his attention on another point: "Refractory... refractory bricks...what kind of bricks are they?" It was something he had never heard of before.

But this name seems... it sounds a bit mysterious and powerful.

"It means exactly what it says. It's fire-resistant and high-temperature-resistant, and also has great pressure-resistance. This is the general production method and process." Having said that, Zhu Yunhuan handed the general process he had written down during his free time to Ma Sanbao.

Ma Sanbao took the rice paper from Zhu Yunhuan's hand.

He handed it to Qin Kui and said, "Master Qin, please keep it."

Qin Kui was still a bit bewildered. Making bricks out of those broken stones? And making them fire-resistant, heat-resistant, and pressure-resistant… could it even work? Even if it could work, and even if it worked so well, what was the point of spending so much money on such fine bricks?

There are downsides to making something complex and difficult.

But there are also advantages: until the final product is completed, everything is played out in the open, and others will never guess his true intention in doing something.

Of course, although Qin Kui had a million questions in his mind, he still carefully and solemnly put away the process and drawings that Ma Sanbao handed to him.

At the same time, he replied, "Your humble servant obeys my orders!"

Water-powered spinning machines, flying shuttle looms, and anthracite all sound like impossible things, but Zhu Yunhuan invented them. At this moment, Qin Kui could not utter a single word of doubt, whether based on his experience of the previous few months or based on his natural fear of imperial power.

Zhu Yunhuan pondered for a moment.

Then he raised his head and added, "As for how to test whether the finished product you made meets my requirements... Song Zhong's men will deliver the coked coal to you later."

Just say this.

Qin Kui was confused again: "Coking? Coal? Testing?"

Although he already had considerable experience working alongside Zhu Yunhuan, Qin Kui couldn't help but internally groan, "What the hell is going on? I've reached this position today, and I'm a well-read man, well-read in the classics, history, and literature. How come I can't understand what Your Majesty is saying?"

"Uh..." Zhu Yunhuan was speechless for a moment. After all, he was still a modern man, and it was inevitable that he would ignore the generation gap caused by hundreds of years.

After pondering for a moment, he could only explain honestly: "What it means is... that coal can burn much hotter than ordinary coal, or even the anthracite sold on the market."

Hearing this, Qin Kui frowned in disbelief.

He understood that it was much hotter fuel, but was it really possible?

As he was in charge of the Ministry of Industry, he naturally came into contact with smelting. He knew that in metal smelting, the hotter the fuel burned, the higher the purity of copper, iron and other materials that could be smelted.

"If such a thing really existed, the Armory would have gone crazy with joy!"

Of course, the moment this thought came into his mind, Qin Kui suddenly felt his heart skip a beat.

He frowned and thought for a moment.

A bold idea suddenly came to mind: higher temperature fuel, refractory bricks... Armory... metal smelting...

Putting all of this together, perhaps the answer is clear: "Your Majesty wants to... create stronger and more powerful weapons?"

Although Qin Kui's subconscious thought was that some of these links were impossible to achieve.

But he knew that these words were spoken by the Majesty in front of him!

Others cannot achieve it.

Your Majesty...but not necessarily!

However, Qin Kui has been trusted and entrusted with important tasks by Zhu Yunhuan from the beginning to now, which shows that his mind is very smart and flexible. Even if he has such thoughts in his mind, even if his heart is still like a raging storm and cannot be calmed, he still keeps his mouth shut and does not say a word.

He took a deep breath and said, "I understand. With coked coal, we can burn it to a high temperature, so we can test whether the bricks we make are up to standard. I will do my best to burn the refractory bricks that Your Majesty wants."

He cleverly got to the point.

Seeing his expression, Zhu Yunhuan actually knew roughly what he was thinking about. Of course, since he dared to reveal these tiny clues, he was certainly not afraid - after all, most people would only think that he would want to improve the existing swords, spears, swords and halberds to make them sharper and more durable. Who would have thought that he wanted to make cannons?

However, Zhu Yunhuan nodded with satisfaction at such a clever ox and horse, saying, "You should personally take charge of this matter."

Qin Kui immediately understood the meaning behind the words: "Your Majesty, please rest assured that the test process will not be delegated to others."

He knew that His Majesty's words meant that he should keep it a secret!

……

The words are divided into two parts.

The snow in Yingtian Prefecture was heavy, and the snow in Beiping Prefecture was even heavier.

In the vast city of Peking, covered with ice and snow, a seemingly inconspicuous three-story house seems particularly peaceful.

In the hospital, heavy snow fell.

Some traces of footsteps have quietly disappeared with time, and only a kneeling figure can be seen in front of the door, covered with snow.
