Luoyang, Fengge Luantai office.

Several prime ministers were a little surprised when they saw the text sent by Wu Yanzhi to build a gunpowder factory. Even though they didn't need to approve it, it still felt like a big deal.

Tongping Zhangshi Zong Chuke said: "Speaking of which, although the king of Donglai is also the envoy of the fire gas, he has the right to decide to build a gunpowder workshop. However, I heard that this gunpowder is very powerful, so I should give a report to the saint. ”

"From a contemptible point of view, there is no need to go through such a big effort! The Holy One will definitely agree. If it can really produce 100 million catties of steel a year, what is this concept? All the land in the world can be cultivated intensively, and the annual increase in grain production is innumerable! Yao Xuan said.

"This matter is very important, I think it is best to report it to the saint!" Wang Fangqing also said.

In the end, they discussed and decided to report the matter to Wu Zetian.

……

Luoyang, the side hall of the temple of the wind.

Wu Zetian listened to their report and smiled slightly: "This kind of trivial matter, let him be in charge!" Since he is a firearms envoy and a copper and iron envoy, of course he has this right!

According to him, all of these 100 million catties of iron can be easily made into steel. I'd like to see how his steelmaking furnace turns molten iron into steel in an instant! It's a pity that I'm too old to walk.

Immediately sent Yao Chong, the official of Xia, and asked him to go to Xingzhou to cooperate with Wu Yanzhi to supervise the gunpowder factory and copper and iron things. At the same time, in the northern capital of Taiyuan, a new weapon and armor workshop was established, and Wu Yanzhi and Yao Chong were asked to handle this matter together!

In the past, we were always worried that there was not enough steel, and in the future, we will have to worry that this steel will not be used up! ”

At this time, Tongping Zhangshi Yang Zaisi said: "Your Majesty! Donglai Wang said in the article that this steel has many uses, and there is no problem of inexhaustibility.

For example, building bridges, building ships. He also said that in the future, it can be used to build a machine, a machine that can walk on its own! ”

"A machine that walks on its own?" Wu Zetian was puzzled.

"Your Majesty, it is true! Zhuge Liang in the Wei and Jin dynasties once invented the wooden ox and flowing horse. The machine he built should be about the same as it. But I've heard that it's very powerful.

According to Donglai Wang, the trial production is currently going very smoothly. The next time he goes back to Luoyang, he can bring a small sample to His Majesty! Yang Zaisi continued.

"Hmmm! That's good! My grandson has a lot of ideas, so I can't be sure that he will come up with something new! ”

This is Zong Chuke said: "Your Majesty, the gunpowder is so powerful, Wei Chen thinks that it is better to send someone to supervise its production, so as to prevent this thing from being learned by foreigners, and also to prevent it from being used by traitors!" ”

When everyone heard it, he had a bad relationship with Wu Yanzhi, did he deliberately provoke it?

Sure enough, when Wu Zetian heard this, her brows furrowed, but she returned to normal in an instant. Then she said, "Good! Just let Zuo Sutai send a superintendent of the imperial history to check it regularly. However, he is not allowed to interfere in any affairs!

You know my habits, I don't like the prison army to interfere very much, of course it's good to make suggestions. Why, it's just that I'm afraid of interfering with the commander's command! The so-called employment is not suspicious, and the suspect is not used! ”

Tongping Zhangshi Yang thought about it again, and the purpose of this Chu Ke sect was not achieved. As long as Wu Zetian asks someone to do something, he will generally give full power. The role of the prison army is very limited, and of course the power of the prison army is very large, and it is the emperor's errand.

……

On the first day of the sixth month of the Zhou calendar, Shahe, Xingzhou, Qiyang Village.

Today is the day of the explosion, and all the people have taken refuge in a safe place dozens of feet away.

These people had never seen gunpowder and had no idea how powerful it was. Wu Yanzhi had already asked the workers to drill holes and place gunpowder.

Since there is no mechanical drilling rig for the time being, a very slow manual drill is used, that is, water is added to the hole and the drill is manually cranked. As long as there are many people, this speed is not too slow.

"Lord Qiyu, all the preparations have been done, a total of 200 holes have been drilled, each hole is two meters deep, five catties of gunpowder are loaded, and a total of just 1,000 catties of gunpowder.

The personnel have all been evacuated to a safe place and can be lit up! Wang Jin said.

There are also a number of officials and miscellaneous servants on guard.

He had already seen the power of the gunpowder during the experimentation period.

"Okay, this first test explosion is under my own command! In the future, there will be Wang Supervisor Lao in charge. Wu Yanzhi said.

"This is where the duty of the lowly lies, and the lowly duty does not dare to shirk!"

"Judge Jiang, please light the fire!" Wu Yanzhi ordered.

Judge Jiang Shipeng took the fire fold that had been prepared in his hand, lowered his head and lit the fuse.

The lead billowed black smoke billowed toward the mine.

For a moment, but there was a loud bang that almost burst everyone's eardrums.

Then, but I saw that the smoke was all over the ground in an instant!

People stood up to see the blasting first.

Before the smoke and dust cleared, countless people rushed up.

"Yikes! This gunpowder is too powerful, and half of the mountain is gone......"

"Yes! It's amazing......"

“……”

Countless people were stunned by the scene in front of them.

"This is an artificial stone, and it won't take a few months! I can't imagine that the problem will be solved with one shot today! Wang Jin sighed.

"The gunpowder invented by the prince is amazing, today is an eye-opener!" Gao Xiancheng said.

Xingzhou prefecture-level officials, county officials from the neighboring Zhaozhou Thorn History, and nearby Nanhe counties were also invited to see the excitement today. They are not allowed to leave the country in normal times (the Tang Dynasty stipulated that state and county officials must be approved by their superiors to leave the country. It was Wu Yanzhi who invited him to Shahe County in the name of the Hebei Observer Envoy.

Because today's day is very important, not only to put the first cannon in the mining field, but also to make the first furnace of molten steel in the converter.

They were invited to watch the pomp and circumstance of these two events. Second, in the end, on their territory, blasting and mining work must also be carried out, so that they can be mentally prepared first.

"Yao Gong, the effect of this blasting is not bad, right?" Wu Yanzhi asked Yao Chong, the official waiter.

"Isn't that good? It really deserves the words 'Breaking the Earth'! Today, I really know the meaning of these four words! King Donglai is really a god and a man! Xia Guan Lang Yao Chong was full of praise.

"Such a grand occasion, if you return to the Shendu next month, you must report to the Holy Lord in detail!" Liu Min, the palace attendant, said.

This person was sent by the imperial court to inspect the production of gunpowder, and he had dealt with Wu Yanzhi many times.

"Let's go, I'll see the effect of this explosion!" Wu Yanzhi said that, jumped into the mine, and checked the eye marks and the size of the ore after the blasting.

The reason why we need to look at the effect is to determine whether our blasting parameters are reasonable.

The so-called blasting parameters refer to the depth of the blast hole, the distance between the bubble holes, the charge amount, the minimum resistance line and so on.

Before each blasting, these data must be designed, and they cannot be messed with.

The unreasonable design of blasting parameters will naturally seriously affect the blasting effect, so there is no need to say more here. Please Baidu "Throw Book Network" Thank you for your support!
