After traveling to ancient times, I relied on my husband to win

During the days that Rong Jiuxuan was in seclusion, Qin Yan was forced to go to the Ministry of Industry every day to study the production of gunpowder.

However, he would go back to the Ministry of Works an hour after having breakfast for Jiang Zhi every day, and would rush back when the time came.

Make a delicious meal for your pregnant wife.

After previous research, Qin Yan thought about the approximate formula of modern gunpowder and wanted to compare it with its origin in Dongwu Kingdom.

One nitre, two yellows, three charcoals, one pound and sixteen ounces, the ratio is 16:2:3

黑火药的最佳比例是74%火硝、11.5%硫、13.5%木炭比例大致是15：2：3

These are okay, but they are not yet ready to be used on the battlefield. If they were to be used on the battlefield, the gunpowder would need to be more powerful, which would greatly reduce the death of soldiers and never achieve national victory.

Thinking of this, Qin Yan looked at a group of officials from the Ministry of Industry who were arguing with each other.

"As long as the amount of gunpowder is increased, the power will definitely increase."

"That's wrong. This is just a small amount of gunpowder. It's far from enough to cause harm to people."

"I think we need to add more saltpeter to really increase the power of gunpowder."

"No, no, we should add more charcoal to increase the power of the gunpowder."

"No, no, too much charcoal will increase the smoke and make it easy to be exposed on the battlefield."

"Neither is right, neither is right. I think joining..."

Qin Yan did not join them, but sat aside and flipped through some documents he took out from the bookshelf, thinking about the improvement of gunpowder in his mind.

Qin Yan thought of something and raised his head suddenly, his eyes shining.

"I know, it's sugar!!"

“???!” Several other officials from the Ministry of Works were arguing. When they heard Qin Yan’s excited shout, they all looked over with confusion.

Seeing their puzzled expressions, Qin Yan simply explained it to them.

"Sugar is a flammable substance. When it encounters high temperature, it will dehydrate rapidly and burn. The combustion of sugar requires an oxidant and high temperature. Potassium nitrate in gunpowder is naturally the best oxidant. The heat from the burning gunpowder provides the high temperature condition. In the end, 60 parts of high-temperature and high-pressure gas are generated, with a ratio of about 1 to 2. This is much more efficient than the combustion of gunpowder alone. Therefore, sugar can be said to be a power amplifier of gunpowder."

"The basic ingredients of traditional gunpowder are saltpeter, sulfur and charcoal. Sulfur can be replaced by realgar, and charcoal can be replaced by grease and asphalt. So the addition of raw materials mentioned by the adults just now will definitely not increase the power of gunpowder."

Everyone was stunned by what Qin Yan said. No one said they understood nor did they say they didn't understand, but anyway, they roughly understood what Qin Yan said.

Qin Yan followed several officials from the Ministry of Works to study the power of gunpowder and how to increase its power.

The effect was obvious, they succeeded, but it took a long time to make just one.

However, after continuous trial and error, the data obtained in the end was quite good.

With this data, Qin Yan no longer needs to keep an eye on the research and development of gunpowder every day. As long as he lets the people in the Ministry of Industry follow the recorded steps, there will be no big problems, and he can just provide guidance from the side.

However, because there was only one of this and it was quite rare, Qin Yan worked with other people from the Ministry of Industry to work overtime and make another one.

Then the emperor was invited to an open space to conduct an experiment. A scarecrow was placed in the middle of the open space and armor was put on the scarecrow.

Everyone was about twenty meters away from the group of straw people, and Qin Yan asked someone to bring up the prepared gunpowder.

Qin Yan introduced the power and performance of the gunpowder, which was basically to prevent any grass from growing within a ten-mile radius.

Call a person who is very good at archery and has a good aim, and ask him to pick up a gunpowder, stand in a safe area and throw the gunpowder at the scarecrow.

boom--

The moment the gunpowder burned to the end, a huge explosion was heard, and everyone felt their ears ringing with the roar.

After the dust from the shock settled, everyone saw that the scarecrow wearing armor was no longer there, but only fragments of armor and wisps of straw remained under his feet.

It makes people's hearts tremble when they see it, and everyone is very excited to see such great power.

The emperor was even more excited and applauded repeatedly.

"Okay, okay, Qin boy, I was right about you. You really bring surprises to me everywhere~"

"Your Majesty, thank you for your praise. I dare not take all the credit for this achievement. During this period, the ministers of the Ministry of Works also helped to complete it. Each of them is very important and has made an indispensable contribution."

"Okay, I understand. My dear ministers have worked hard. You have made great contributions this time. From now on, my Dongwu Kingdom will no longer be afraid of threats from others."

The people behind looked at each other, trying to guess what the emperor was thinking.

They all knelt down and shouted long live.

"Our emperor is wise and wise, and Dongwu will last forever."

"Our emperor is wise and wise, and Dongwu will last forever."

"Our emperor is wise and wise, and Dongwu will last forever."

……

With the big thing settled, Qin Yan finally relaxed and returned home.

It has been more than a month since all this was settled. Jiang Zhi's belly has begun to show a little bit, and she still eats and takes pregnancy-maintaining medicine every day.

Although her belly was bigger, it didn't affect her at all. She ate and drank as usual. Her face just became a little rounder, but there was no extra fat.

Jiang Zhi's belly was slightly bulging, and the rest of her figure remained the same. Wearing loose clothes, you couldn't tell that Jiang Zhi was pregnant.

It’s just that Qin Yan was more careful and cautious when dealing with Jiang Zhi.

After a month of seclusion, Rong Jiuxuan laughed wildly while holding the lip balm and rouge he had successfully made.

"Ahahaha, I succeeded, I succeeded, I made this set of lip balm and rouge. Ahahaha, I really am a genius, this meal should be mine. Hahaha."

Looking at the crazy man, Qin Yan silently pulled Jiang Zhi a little further away from him. Maybe he looked like a fool.

After Rong Jiuxuan went crazy, he felt extremely tired. He went back in a daze and fell asleep.

Jiang Zhi was a little worried. "Is he like this because of the stress he endured before? Is he okay? Should we find a doctor for him?"

Qin Yan held her hand and comforted her softly, "No, you don't have to worry. He is just tired these days. He will be fine after he goes back to sleep. Don't worry about others, just worry about yourself."

"Me? What's wrong with me? Am I fine?"

Jiang Zhi was puzzled.

Qin Yan looked at her confused look and smiled helplessly, rubbing her head. "Okay, it's not that you have a problem with your body, it's just that I was busy going to the Ministry of Industry this month and neglected you. Now it's time to take you to the prenatal check-up, otherwise what if there is any problem with the baby? Don't you think so?"

"You're right, let's go now."
