Roughly calculated, 500 mu is 115,000 catties of grain.

It would not be too much to say that she is one of the largest households in the entire Tongyang County.

It just so happened that her mother's family opened a steamed bun house, and she opened a winery by herself, and she needed to use grain, and she didn't sell it, and after filling the warehouse of the steamed bun factory, the rest was piled up in the grain cellar of the winery.

During the whole process, there were no big waves in body and mind, and he was all planning to invent an artifact that would end the battle quickly.

It's a pity that I can't think of it even after racking my brains, I remember her going round and round.

Li Niang comforted her and said: "There are so many capable strategists, the generals of Zhenguo can't invent such perfect things, second miss, don't bother, you have always slashed and stabbed with knives and guns, and the fighting methods of each weapon are different, and the defense is not the same." ”

"Alas, no, the fighting style of each weapon is different, but the defense is the same, it is nothing more than unloading and blocking heavy blows.

I'm almost having a clue. ”

Su Qingyan's mind flashed just now, but she disappeared before she caught it, and she turned in circles in the yard even more worriedly.

Suddenly, she heard the birds, and her heart was open.

"It's this!" Su Qingyan shouted excitedly, turned her head and ran to the office, she went back to find pen, ink, paper, inkstone, and drew the shape of a bird's cage.

Li Niang was puzzled, she said: "The canary in the cage is not free, but it is safe!" If we also build a big cage to protect the people inside, in this way, we can minimize casualties. ”

Su Qingyan said, and threw another design drawing: "No, if a person carries such a heavy cage, then he will not have the physical strength and energy to fight, and he has to think again." ”

"Second Miss, it's better to design the cage to be bigger, one person is in charge of carrying the cage and running, and the other is in charge of fighting."

"Good idea, but it's not two people, if you make the cage bigger, those six or seven people are the best, they attack in all directions, it will be safer."

Su Qingyan quickly drew on the paper, constantly imagining various possibilities, and in the end, she directly designed a big bird for ten people

Cage.

Four people fight the cage, and six people control the spear with spring assistance.

The spear had three layers at the top, the middle, and the bottom. Piercing out as needed, the tail of the gun is connected to the cage, which can be pulled back again, and then with the help of the next elastic force of the spring

To be sent.

Elsewhere, the birdcage only has a small hole in the birdcage to see the outside view, and the knives and spears outside cannot penetrate at all.

The person in charge of carrying the cage does not have to carry the cage all the time, as long as he runs a distance while charging into battle.

When the time comes, move left and right slightly, and put the cage on the ground, like an upside-down bowl, so as not to delay the other six soldiers to fight, these four can still sit on the ground and rest, comfortable and ruthless.

After drawing the design drawings, Su Qingyan planned to find someone to construct it, but this time it was really difficult for the blacksmith.

Iron was more expensive in this era, although it was not as expensive as copper, silver, and gold, but it was not squandered at will by people in mountain nests.

Usually blacksmiths make kitchen knives and hoes or something, and there are still many people who can't afford it, and now it is really difficult for him to get such a large iron cage.

Su Qingyan searched for blacksmiths of all sizes in Tongyang County, but none of them could do this errand.

Su Qingyan was very disappointed, but at the same time, he was also very excited.

Ordinary people can't do it, which means that they won't be easily imitated, she is a monopoly!

If she could make it.

Regarding the casting part, she is not deeply involved, and the only two things that have an impression are the aluminum pots cast by her grandmother when she was a child and the lost-wax silver casting process she saw in various videos.

Perhaps, you can try it with the lost wax method?

Su Qingyan ordered people to find the large and small beeswax in Tongyang County, and after fusion, pour in various abrasives, and then spliced them together to modify and polish.

After several days of splicing, she and five blacksmiths finally put the defensive birdcage made of beeswax in a fireproof material mixed with quartz sand and dry stone powder.

As the kiln heats up, the beeswax melts and disappears, and the blacksmiths take the opportunity to pour buckets of molten iron into the top.

After the molten iron solidified, the mud core was pulled out, and a huge defensive birdcage appeared in front of everyone.

It's just that the defensive birdcage cast is not as delicate as Su Qingyan thought, with more than two hundred catties, which is really not suitable for moving on the battlefield.

Fortunately, those old blacksmiths said that they could polish it, and it took more than ten days to turn the iron guy who was more than 200 catties into 100 catties.

And those springs or something, the object is relatively small, and it is very easy to do, because at this time there is already such a labor-saving and lethal thing as a bow. The blacksmiths have some experience.

In late June, General Wei brought people to replenish the supply, and by the way, Su Qingyan hurriedly took him to see the elaborate defensive birdcage.

But unfortunately, it was ruthlessly rejected by General Wei.

"This kind of thing can't be mass-produced, and it's not convenient to handle, so if I take one back, who is it for?

Moreover, if you want several people to move forward synchronously, you need to run in, and I'm afraid that before you can run in something, the war will be over. ”

"Ahh Is the war coming to an end? Su Qingyan spent so much manpower and material resources that she was very unhappy to be rejected, but she was still happy to hear the news of the end of the war.

General Wei is not a person who likes to talk about family life, so he didn't say much more, and left after saying goodbye.

Su Qingyan looked at the huge birdcage and felt that it was a pity that the flame was strange, so she ordered someone to carry it to her office in the kiln factory, in the room at the back.

She didn't know why she liked building an office so much, but she always felt safe when she built an office.

It's just a pity that such a great invention didn't come in handy.

Su Qingyan sighed around the bird cage and returned to the wine shop.

Seeing that Su Qingyan's feet were busy all day long, Liu specially took advantage of the hot weather and the new clothes shop had no business, so he specially stewed pigeon soup for Su Qingyan.

I thought I was going to make up for her, but I didn't expect Su Qingyan to feel sick to her stomach as soon as she pushed the door open, and ran out in a hurry with her mouth covered.

"Oh, girl, what's wrong with you? Are you tired? Liu was startled, put down the pigeon soup with a bang, and went back to help Su Qingyan. Su Qingyan smelled the smell of pigeon soup on Liu's body, and when she saw her approaching, she vomited even harder.

Liu hurriedly took two steps back and called Shui Ju to get water.

"What's wrong with you, are you too tired the first two days? I look like you've been losing your appetite for the other day. ”

"No, mother, I'm busy with other nicknames."

"Qingyan, you won't have it, right?" Qin Shi pushed open the door and came out, nervously pressing Su Qingyan's pulse.

Su Qingyan rinsed her mouth and said in surprise: "Mother still takes the pulse?" ”

"Other mothers won't, it's this happy pulse, I heard that there are two pulses, it's easy to get out, my mother wants to try."

Qin Shi said and pressed it again, like a decent, very interesting.

It's a pity that she hasn't touched it for a long time.

Li Niang leaned over and touched it, and said, "There is only one pulse." ”

"Oh, that's not pregnant." Su Qingyan felt a little lost in her heart, and she didn't want to eat anymore, so she went back to the house in good spirits.

But in the evening, she was hungry early, so she ate one meal first, and then two bowls of rice at dinner.

Both the Liu family and the Qin family felt that she was abnormal, but they didn't dare to say it for fear of hurting Su Qingyan's heart.

The next day, Yang would not come again to report on the trivialities of the Suasi family.

Before he could speak, he was invited into Su Qingyan's room by the Liu family.

"Doctor Yang, my daughter has been unwell recently, maybe she is tired, you can see if there is a big problem, and it is good to prescribe a prescription for her to recuperate."
