Queen Mother's A Scientist

Seeing that Hua Qingxue's face changed, Li Jingnan immediately became nervous, "what's the matter? Is there something wrong with the weapon? "

Hua Qingxue was silent for a while and told him, "some time ago... Several Liao soldiers sneaked into the barracks and took away our craftsmen."

Li Jingnan almost raised her eyebrows when she heard the speech“ Liaobing sneaked into Qingzhou camp?! Where's Fu tingye? He didn't find out?! "

"The other party was sent to the barracks dressed up as a seriously injured Qi soldier. The general didn't know." Hua Qingxue didn't mention that she was almost taken away, but sighed, "the Liao soldiers are well prepared. We can't guard against it, and the general can't take care of it face to face."

Li Jingnan slapped on the table with resentment! The cup that drank white gourd tea just now shook a few times.

"These dogs! I'll kill them all sooner or later! "

Li Jingnan grew up in the shadow of Liao's invasion of Daqi from the moment he remembered, and his hatred for the Liao people is deep-rooted.

At first, Hua Qingxue didn't feel much about the countries on both sides, but with the closer and closer relationship with Fu tingye and Li Jingnan, she lived here and gradually had feelings for Daqi.

Accordingly, she began to have resistance to the Liao Dynasty, especially after the incident of blacksmith Liu, although Hua Qingxue was not Qi people, her position was basically consistent with that of Qi people.

Hua Qingxue's voice was stuffy: "the Liao soldiers are still. They must be making new weapons. Once the weapons are completed, they will attack again."

Li Jingnan's small face sank, and his good mood was swept away.

Although he is young, he is also very clear that the national strength and military strength of Daqi are too weak compared with that of Daliao. Taking the initiative is tantamount to hitting stones with eggs! But it's really frustrating to wait for the other party to hit the door!

It was not easy for Hua Qingxue to make a new weapon. He thought he saw hope, but he only won one game and was kidnapped by the Liao army!

Can't Daqi really guard the world?

"Well, don't frown hard. Frown every day when you are so young. Be careful that you will grow old quickly in the future." Hua Qingxue doesn't want Li Jingnan to have too much burden on his mind and try to relax his tone. "Don't worry about the barracks. The general has stepped up the training of a group of archers to reinforce the long-range attack ability of the army. I also mean that the Liao army makes the surrounding countries cold in the name of iron cavalry. We don't have to fight hard."

Li Jingnan thought of Hua Qingxue's bow with a range of 400 steps. His mood improved slightly and nodded in agreement. "Yes, we should develop our own advantages in the future. If we can't fight cavalry, we should fight long-range archers!"

When he finished, he was worried, "but... Liao people's riding and shooting skills are very good. If they figure out this kind of bow one day, we..."

"Sooner or later." Hua Qingxue said.

Li Jingnan was stunned and looked at Xianghua light snow.

"Once on the battlefield, there will be damage. As long as the Liao soldiers capture a few of our bows and arrows, disassemble the structure, and find craftsmen to ponder for a few days, they will certainly find the mystery." Hua Qingxue's voice is still soft, but his words are extremely cruel, "so it's sooner or later that the bow and arrow will be copied. We can't place all our hopes on the bow. It may help us win once or twice, but it will never be permanent."

Li Jingnan listened, her small face tightened tightly, pursed her lips and remained silent.

Hua Qingxue knows how much he wants to hit liaobing, so she can't bear to look at such Li Jingnan

"Come on, I'll show you something." Hua Qingxue stood up and took Li Jingnan to the west house.

Close to the eunuch, Xiaodou followed up with low eyebrows.

Hua Qingxue seems to be very taboo and says to Xiaodou, "wait outside first."

Xiaodou was stunned and went to see Li Jingnan.

He has always served closely. Even if Li Jingnan squatted in the thatched cottage, he never left for more than half a step!

Besides, the Emperor didn't speak. Why should she?!

Unexpectedly, Li Jingnan almost didn't think about it. He waved, "wait outside."

"..." Xiaodou stood under the eaves with his head down.

Hua Qingxue immediately closed the door.

"What are you going to give me? So mysterious... "Li Jingnan curiously walked into the room and saw that the whole wall was full of wooden shelves! It's full of handmade soap. I'm amazed!

"Wow You did it all by yourself?! "

"Yes, after being proficient, I will make two pots every day." Hua Qingxue took a piece and handed it to him, "did you run out of those I gave you last time? Don't use it. Use this batch of new soap. It's better than the original one. "

Li Jingnan nodded again and again, not polite to her, "then you can install some more for me, and I'll send some pieces to my mother."

Hua Qingxue heard that the Empress Dowager would also use her handmade soap? This feeling is really wonderful!

She smiled and said, "well, I'll decorate you with everything. You can reward the minister's family members and help me advertise!"

"What is advertising?" Li Jingnan looked at her inexplicably.

"Is the meaning of publicity and promotion."

After reading the handmade soap, Hua Qingxue went to a table, picked up a handful of paper with various strange patterns, searched for it, took out some from the paper and handed them to Li Jingnan.

"I haven't shown the new weapon to the second person yet." Hua Qingxue said with rare pride, "if you do it, I can guarantee that even if it is stolen by Liao soldiers, they can't do it."

Li Jingnan didn't dare to underestimate it and looked serious.

But he looked left and right. He just couldn't see what was painted on the paper

"What is this?" He looked at the paper upside down in his hand, "it's round and round. You can't chop it. How can you use it on the battlefield?"

"Use with these." Hua Qingxue handed him another few pieces of paper.

Li Jingnan still can't understand.

He was a little discouraged. "Tell me directly. What's the use of this thing?"

"This is called gunpowder. You can understand it as a firecracker 100 times more powerful than fireworks." Hua Qingxue put all the drawings in front of him and explained one by one, "once gunpowder is made, we can start making rockets, guns and artillery. Each weapon has strong lethality!"

"A hundred times more powerful than fireworks and firecrackers?" Li Jingnan felt a little unimaginable, and her expression turned into a wrinkled ball.

Probably because... In the great Qi Dynasty, the power of fireworks and firecrackers is too weak. People can listen at most.

Hua Qingxue thinks that the problem should be in the process of purification, which leads to the failure of nitrate to play its due role.

In fact, in the Song Dynasty, gunpowder weapons were already very developed. Not only the prototype of fire gun, but also zhentianlei and thunderbolt gun were born in the Song Dynasty.

Unfortunately, although the Qi Dynasty is close to the Song Dynasty in all aspects, its military strength... It's hard to say.

The original ancient gunpowder, that is, the mixture of nitrate, sulfur and charcoal, has not attracted people's attention and is difficult to be used in the battlefield. However, after improvement, the combination of potassium nitrate, sulfur and charcoal according to a certain ratio has great power! Almost as good as postmodern explosives!

Huaqingxue's biggest headache now is not the production of gunpowder, but the material selection of the lead part, which should be flammable, uniform speed and have certain moisture resistance.

The most conservative method is to weave cotton thread into thick thread. The disadvantage is that it is too easy to be damp. Once it encounters bad weather, it is very likely to be extinguished halfway.

The lead wire doesn't work, and the most powerful artillery can't exert its power.

Hua Qingxue is still trying to refine sodium chlorate.

——When sodium chlorate is heated, it will release oxygen. Oxygen is the best combustion supporting material. As long as it is added into the cotton thread, it can solve all her concerns.

These problems are too difficult for Li Jingnan to understand. Hua Qingxue can only explain them roughly.

"... in short, the general has agreed to set up a firearm battalion. He has sent people to help me. If everything goes well, we will soon have the first batch of artillery." Hua Qingxue put away the drawings she had drawn recently, with some longing in her eyes, "they will become the most brave soldiers in Daqi."

"But he didn't report it to the court!" Li Jingnan frowned, a little angry.

Even if you want to do such a big event, you must report it to the imperial court first!

"The general may be worried about me..." Hua Qingxue smiled shyly. "He was afraid that I would be punished if I failed, so he took it for me and reported it to the court. Didn't he have to wait for the court to approve the money? It will take a long time. "

Li Jingnan reluctantly accepted the explanation and said unhappily, "don't worry, as long as it is beneficial to the country and the people, I will approve it! However... It's really not fast to allocate silver from the Treasury. When my father was in power, he always reduced taxes and recuperated, so these years... The Treasury really didn't have much money. "

Hua Qingxue nodded to show understanding, in a sincere tone, "the first emperor is a good emperor."

In a simple and plain sentence, somehow, Li Jingnan felt his nose sour.

After the emperor's death for so long, he had never heard anyone evaluate his father like this... Even the empress mother didn't agree with him when she mentioned his father.

He deliberately raised a big smiling face, trying to cover his red eyes, and said, "I happen to be making a private visit. I'll live with you these days! Let's see how you make a new weapon, shall we? "

Hua Qingxue smiled and nodded, "OK, let you see. If you are satisfied, remember to go back and allocate funds to me. Although the general said he had money, I am a little worried that he would make a big face. After all, if this thing really needs mass production, it will not happen overnight, nor tens of thousands of liang of silver..."

Li Jingnan raised his head proudly, "then you can find me right. Fu tingye is a big general. How much salary can he get every year? Even if the king is sealed, he can set up a private name to collect taxes and collect money. He is also the king just sealed this year. He can't save much money! No matter how empty the Treasury is, it must be richer than Fu tingye! "

Hua Qingxue couldn't help laughing when she heard Li Jingnan show off her wealth.

Li Jingnan smiled when she saw her smile.

He couldn't tell why he trusted China light snow so much.

Maybe it was a short time when Renqiu was in trouble and depended on each other Maybe it's because Hua Qingxue always has strange theories in his mouth?

She was full of miracles, just like those pancreatic soap on the wooden shelf. She said and did it.

Many unimaginable things seemed easy for her to do.

So

Li Jingnan looked at the stack of drawings on the table and thought: this time, she will be able to do it.
