Poor family mother and son

Facing the real suppression of bloodlines, Little Treasure would not dare to make mistakes. A "paper tiger" is also a tiger, not to mention that he needs to ask for technical questions.

"Mom, I, a loose science student, have encountered a problem, you have to take care of it!" Xiaobao said coquettishly.

No mother can resist her children's acting like a baby, especially a boy who is bound to "be manly".

These days, Xiaobao would mention the titles of father and mother from time to time. At first, Chu Qing thought it was because Xiaobao saw that some of the hired workers brought their families to work, and envied them for having a father.

But these days, I have tasted it carefully, no.

Every time the child faces Huang Zhong's careful teaching, or Huang Zhong accompanies him to modify something, he always has a look of admiration and regret on his face, probably thinking that he can accompany his mother, but he has not yet done something for his father. matter.

Children also miss home and want their own home.

Thinking of it this way, Chu Qing's heart softened, and she put away her thought of blaming him for letting his brothers accompany him on adventures after learning half of it.

"Why do you think of tinkering with mortars?" Chu Qing asked.

"The emperor wants to leave without conscience, and our family has no advantage!" Xiaobao said: "Mom, we need enough self-protection ability;

We need better weapons than heartless guns, even if the range is longer, it is an advantage;

The Chu family only has a few flintlock guns, and it doesn't seem to have much protection and deterrent effect-the ammunition of those things is too slow;
Mom, even if there is only one tiger, no one dares to provoke it easily, but facing a group of rabbits, even a child dares to punch and kick a few times;

Mom, I want to arm you like a real tigress! "

Chu Qing: "...Is it because I haven't beaten you for a long time?!"

Chu Qing is really funny and angry: "I am 23 years old and I am learning to bow and horse. I hold an iron-bodied bow in my hand, and it is full of vermilion buckles. Everyone in the tent praises me;

You say I'm a tigress, what am I trying to do? "

Xiaobao: "..."

With the tigress showing his power, Xiaobao didn't dare to say anything more.

Niangqin used to have real power but no status, but now she has status but no real power. The result of the two is the same, such as "a three-year-old child goes through the market with gold".

And Xiaobao also thought that although the battle was won, the emperor immediately took away the blueprint of the "unconscionable cannon", what does this mean?Beware of the Chu family.

Although his mother resigned and did not resign from the secret investigation department in the end, Xiaobao thinks that it is not that he refuses to resign, but that it is not time.

When the emperor gradually sent more manpower to replace the detectives lurking in the country of Voss, the mother's last real job would be gone.

At that time, Niangqin will be even more dangerous.

Chu Qing: "Son, you just need to learn the arts and martial arts well, protect your own home, don't worry about everything, this one follows the motor to fight, mother also learned the culture of war-

Standing at the gate of the camp, the three armies shouted, and the big and small children listened to Genmiao:

The first drum is made of Zhanfan; the second drum is used for tight battle robes;

Everyone has a reward when you go forward, and you get a knife when you step back.

Your worried mother knows all about it, and the militarized management mother already cares about it, son, just eat and sleep well, and be happy as a sunny boy Xiaobao. "

Xiaobao: "...Mother, speak well!"

Chu Qing: "Well, tell me why you chose to study mortars?"

This is really a mystery. For Chu Qing and Xiaobao who have never been in contact with arms, these things are basically out of imagination. She really wants to know why Xiaobao wants to make mortars.

Xiaobao: "Didn't you say last time, 'We have too many big and small mountains here, if only there was a mortar that could fight cows across the mountains'?"

Chu Qing: "Uh..."

It seems to have said so.

Chu Qing: "What difficulties did you encounter?"

Xiaobao: "Ignition, it doesn't ignite every time. It doesn't matter if the grenade fails to fire. Anyway, pull the tab and throw it out, but the cannon doesn't work. We dare not go close to check;
Mom, I can't figure out the fuse! "

Chu Qing: "I'm also thinking about this matter. My mother learned to blow glass recently, just to get some tools to make trigger medicine."

The existence of the craftsmen, especially Kang Xi, gave Chu Qing great confidence.

Not to mention anything else, with the help of Kong Xi, many units of measurement were well unified and realized.

For example, to measure body temperature, it is very unreliable to rely on touching the forehead with the hand, or feeling whether the forehead is hot or not.

If both of them have a fever, how can they take each other's temperature without help from others? .

So Chu Qing told Kang Xi to make a thermometer.

Now that we can make glass at home, let's blow a small tube and fill it with mercury.

If the temperature of the ice-water mixture is set to zero degrees, then the water boils at one hundred degrees, and the length of the expansion of mercury between these two temperatures is divided into one hundred parts, and a relatively accurate measurement result is obtained.

So the task that Chu Qing gave Kang Xi recently was to help her make a glass distillation vessel, such as a flask, a condenser, a retort, whatever you can think of, thinking about getting some silver fulminate.

If you can work it out, you can come back and make toilet water or something.

"Pricking medicine?" Xiaobao's eyes lit up.

Chu Qing reassured Xiaobao: "Son, don't think that if you shoot it out without a conscience, our advantage will be lost, it's a gunpowder bag catapult;
Didn't Wei Chengyi say that the cannons they make always misfire?Misfiring has nothing to do with the barrel, it's a problem with the gunpowder;
Mother told you before when she taught you how to make black powder. Their formula and ingredients are wrong. Compared with the gunpowder they use, ours is more advanced. This is the advantage;

However, mortars have to be built, and your grandpa Huang said that your shells..."

Xiaobao immediately shouted: "It turns out that Grandpa Huang sold me!"

"You'd better design an explosion-proof helmet for me first, I want to get silver fulminate, it's dangerous!" Chu Qing hurriedly pulled the words back.

You can't let Xiaobao get entangled in who "sells out" him, otherwise Chu Qing won't be able to grasp his movements in the future—this kid, all his wisdom will be used against his mother!
To be honest, people who have been away from the state of college entrance examination for decades, it will take a lot of brains to pick up even the most basic chemistry knowledge.

In particular, it is necessary to understand the physical names corresponding to those chemical names.

There must be sulfuric acid, there must be nitric acid, there must be alcohol, there must be silver...

Sulfuric acid is heated together with natural saltpeter to obtain nitric acid; alcohol is obtained by distilling shochu; finally, nitric acid, pure metal silver and alcohol are reacted together to produce silver fulminate.

Although mercury fulminate is safer than silver fulminate, what our family can take out immediately is silver, as much as you want!
Chu Qing: "If I can tinker with thunder sour silver, then other children will light firecrackers, and mother will let you play and throw firecrackers!"

Wrap a little silver fulminate with coarse sand, stick it tightly with some rosin, and drop it.

It's easy to say, but the raw materials are not easy to find, Linyang County doesn't even have an alchemist, Chu Qing is ready to develop a second career, and goes out to cheat money as an alchemist.

The conversation that followed turned into a discussion between the two of them discussing whether stone gall is easy to get or green alum, and then where to get it, how to get it, how much to get...
