Daming: The system rejected my request for salted fish

Chapter 914

"Yes, teacher. I extracted mercury fulminate according to your instructions!"

"Yes, you do have a talent for this!"

During this period, Wei Wu focused his main energy on imparting knowledge and did not pay attention to the situation of mercury fulminate.

He thought Xu Miao would ask him for advice, but this guy actually came up with it without saying anything.

In fact, what Wei Wu didn't know was that Xu Miao had never thought of asking him about the issue of mercury fulminate.

Because in Xu Miao's mind, extracting mercury fulminate was the homework assigned to him by Wei Wu, and it was the teacher testing the students.

The main reason was that when Wei Wu explained the extraction method to him, he described the steps in too much detail.

If he still goes to the teacher for advice in this situation, it only proves that he is a dull and useless student.

In order not to disappoint his teacher, he tried his best to prove to Wei Wu that he had not accepted the wrong student.

So, mercury fulminate was discovered by Xu Miao in this accidental misunderstanding.

Now, hearing Wei Wu personally praising his talent, Xu Miao's excitement was difficult to describe in words.

Because he finally experienced the feeling of being recognized, and this feeling is very comfortable!

After praising Xu Miao, Wei Wu turned to look at Yang Chao.

"You're really quick here. Xu Miao just extracted mercury fulminate, and you've already made the mortar."

Hearing Wei Wu's words, Yang Chao scratched his head a little embarrassedly, and then said bluntly:

"Well, actually, after you mentioned the mortar that day, we found the people from the blacksmith team that night."

"It's not that the mortar was made after mercury fulminate was extracted. We made it the day after you mentioned it."

"Even the shells are ready, all we need is mercury fulminate, so I went to Xu Miao to see if he could get some mercury fulminate to make the percussion cap."

Ok!

It turns out that I have become a conservative. These people are worthy of being firearms dealers. Their impatience is almost as bad as gunpowder.

After secretly complaining in his heart, Wei Wu chuckled and shook his head, then continued:

"So, when you learned that Xu Miao had already refined mercury fulminate, you two hit it off and immediately built the mortar."

Yang Chao and Xu Miao nodded immediately. Seeing this, Wei Wu pondered for a moment before asking another question.

"So, were you tested before you came to see me?"

Xu Miao studied chemistry, so no one would ask him about firearms testing, so Wei Wu spoke right after he finished asking Yang Chao.

"The shells haven't been tested yet. We wanted to wait for you to see them, but we've already made the percussion cap using mercury fulminate."

"And after several tests, as you said, the percussion cap is indeed very suitable as a firing mechanism for shells and bullets."

At this point, Yang Chao couldn't help but sighed, and then said with regret:

"I originally thought I could use it to replace gunpowder, but after testing, I found that mercury fulminate is too dangerous."

"You don't even need an open flame to light it. You just sprinkle it on a rock and hit it with a hammer to make it explode."

"Although this thing is powerful, it is too unstable and can only be used as an explosive."

After listening to what Yang Chao said, Wei Wu smiled slightly, then looked at Yang Chao and Xu Miao and explained:

"Mercury fulminate is indeed very powerful, but it has two disadvantages: one is its instability, and the other is that its energy is released too quickly."

"It's unstable because it's flammable and explosive, and it releases energy so quickly because it burns and explodes ten times faster than gunpowder."

"Of course, these two points cannot actually be considered shortcomings. It's just that we lack the ability to make good use of them."

Hearing that the combustion speed of mercury fulminate was ten times that of gunpowder, Yang Chao felt very uncomfortable!

Such a good thing cannot be used as gunpowder, otherwise the power of firearms will be greatly increased by several levels.

In fact, if mercury fulminate could really replace gunpowder, Wei Wu would have taken it out long ago without waiting for Yang Chao to covet it.

It is because of these two defects that it cannot be used routinely on the battlefield like black powder.

If the army were really allowed to take it to the battlefield, this thing might give the army a surprise before the enemy even makes a move.

Therefore, the role of mercury fulminate at this stage is to utilize its instability and extremely fast energy release rate.

Used to provide initial kinetic energy to metal fixed bullets or projectile-type ammunition such as artillery shells.

After explaining to Yang Chao and Xu Miao, Wei Wu decided not to stay at home any longer.

"Since you've built it, I definitely have to go and see it. Let's go! Let's go to the Institute of Science and Technology to test the cannon!"

As he spoke, Wei Wu turned and left. Seeing this, Xu Miao and Yang Chao hurriedly followed him.

Just as Wei Wu and the others were about to leave the courtyard, Liya happened to walk in from outside.

"Master! Are you going out?"

"Well, let's go to the Institute of Science and Technology. What's going on?"

Ever since Wei Wu sent Manager Huang to be the manager of Bi Hai Chao Sheng Lou, he has never chosen another manager.

Zhu Yuxuan is basically in charge of the household accounts, while the servants are left to Liya and the other maids.

Of course, Qingxia is doing business outside, and Nazha and Reba are still young, so it is mainly Liya who takes care of the household affairs.

So Wei Wu knew that Leah came to him suddenly, most likely because of something she was not qualified to decide.

The fact was just as Wei Wu thought. Upon hearing his question, Liya immediately spoke:

"It's like this, Master. Sister Cheng came to me and said she wanted to resign. I can't make the decision, so I had no choice but to come to you, Master."

"Sister Cheng?"

Wei Wu looked at Liya in confusion. He really had no impression of who this Sister Cheng was. Fortunately, Liya spoke in time.

"Master, she's our cook! You even said her cooking was delicious!"

"Oh~ It's the cook! But why is she leaving so suddenly when she's doing such a good job? What injustice did she suffer?"

"No, they said they were getting married, and her in-laws wanted her to stay at home to take care of her husband and future children."

After learning the reason, Wei Wu immediately smiled and nodded.

"Getting married is a good thing! But she is also an elder in the family after all. As the young master, I can't not show some appreciation."

"It's just that I have to go out for something right now. How about this! You tell her, and I'll talk to her in person when I get back!"

After saying that, without waiting for Liya's response, Wei Wu took Yang Chao and Xu Miao and rushed to the Institute of Science and Technology.
