Chapter 275: Fire // Medicine is the magic weapon to win

Dazzling white flowers bloom in the sky, and finally fall silent, leaving only the stars and the unpleasant smell that permeates the air.

Chu Xujun said with regret: "It's too high here, if we change places, we can also put some red, green, purple, yellow, colorful, and more ornamental."

Wei Ling didn't care about the color, he was full of curiosity: "What is this made of?"

Chu Xujun saw that his expression was serious, far from being the warmth and pettiness of Fang Cai.

She looked at the fireworks in her hand and remembered about one of the four great inventions of ancient times - fire// medicine.

This is the basis for being used as a thermal weapon, but the Chinese people only use it as festive fireworks and firecrackers.

Apparently she was also the one who saw the festive fireworks.

But Wei Ling, what he saw, was fire// medicine.

This is even more beyond Chu Xujun's knowledge, but she knows that this is very important.

Now that she reacted, she felt strange, why didn't she think of it in advance?

Probably still the inertia of life in peacetime.

She wanted to make paper because she couldn't stand the discomfort of toilet chips and making "sanitary napkins" from plant ashes.

She remembers that saltpeter made ice because there was no air conditioning in ancient times and she was afraid of heat.

Cement is too inconvenient to travel, and she also wants her buttocks not to be tossed apart by the carriage.

And the three high-yield crops are because the staple food in ancient times was brown rice, which is really not easy to swallow.

These are all related to all aspects of Chu Xujun's clothing, food, housing and transportation as a little woman, and the purchase of good horses is because the Hun cavalry is fierce, and the sweat and blood of the ancient northwest are really thunderous.

Until today, I actually remembered that fire // medicine is the magic weapon to win, probably because the lights are dark.

The most important thing is that ice making has the same raw material as fire// medicine, which is saltpeter.

This didn't make her think of it, her brain was not as good as other time-traveling predecessors.

Chu Xujun was stunned and said, "I remember to use saltpeter, charcoal, and the most important sulfur. What you smell is what it smells."

System Informed Know-How, which provides the relevant basics in the mind.

As soon as he was reminded of this, Wei Ling remembered this smell, he had smelled it, and those underground hot springs would have such a smell from time to time in some places.

Wei Ling: "Where's the ratio?" Raw materials are important, and the ratio is even more important.

Chu Xujun shook his head: "I don't know much about this, you have to wait for me to investigate."

Wei Ling pulled Chu Xujun: "Let's go, let's go find Right Chase and Doctor Pang."

Chu Xujun was pulled urgently: "Hey, my soup woman."

Wei Ling stopped, and she took it back.

Xu felt that the movement was too slow, Wei Ling turned her over and picked her up directly.

Run under the lookout.

Along the road, soldiers greeted, "General, but something happened?"

"No, appease everyone." Wei Ling responded.

"Yes, General." Then he didn't squint at the fact that there was a woman in the general's arms.

Soon, the news that the general ran away at night with the general's wife replaced the rumor that "something happened".

Compared with the southern attack of the Huns, everyone is obviously more happy with the general's "private affairs".

And Chu Xujun, who was held in Wei Ling's arms, her first reaction was that she was worthy of being a macho man, although she had a fairy face, her core strength was like this.

And then, oh my God, there's people watching along the way!

Shen Youchai was just about to ask where those movements came from, but he was caught by the general again, and found that he didn't need to do anything more to deal with the "rumors".

Regarding this "misunderstanding" that started by the two of them and dissipated by the two of them, what else can Shen Youchai say?

I can only "forgive" them.

Soon, Wei Ling's words made Shen Youchai forget about this "little thing": "You say, a weapon that can fire on its own?"

Wei Ling nodded: "Yes, saltpeter is original

Hoard some, charcoal is easy to obtain, it's this sulfur, we have to consult Doctor Pang."

Sulfur can cure skin diseases, and healers will collect it and know how to collect it.

When Doctor Pang heard that it was such a big deal, he couldn't help but glance at Chu Xujun more, and he had a hunch that this matter was probably related to this beautiful little girl.

It is not difficult to collect one or two sulfur, but the difficult thing is to have a large amount of sulfur at a time.

On top of that, they don't know the proportions.

Chu Xujun quickly found out that 75% saltpeter, 10% sulfur, and 15% charcoal.

The difficulty is how to translate the proportions into numbers that the ancients could understand.

Before saltpeter ice, 1:1, it was very simple, and half of them could understand.

Now in the absence of a score, it is difficult for Chu Xujun to express.

She figured out a piece of paper and cut it into ten pieces of paper of equal size and length.

Three men stared at her hand.

She took a piece of paper and said, "This is brimstone."

The three people in front of them nodded.

Chu Xujun took another piece of paper, took out another one and folded it in half, and took half of it: "This is charcoal."

Then she put that half into the other seven and made a pile: "This is saltpeter." Potassium nitrate, to be exact.

The three of them nodded their heads in understanding.

Saltpeter accounts for the largest proportion, followed by charcoal, and sulfur is the least.

They didn't bother to ask at this time, why Chu Xujun understood this.

Time is tight, the task is heavy, and if you have the kung fu to make the first fire// medicine, isn't it?

After that, it was a tent to "live together", and it was difficult for Chu Xujun to see Wei Ling, who left early and returned late.

In addition, they chose an open place in the distance and blew up two or three times from time to time.

Chu Xujun stayed, mainly to appease the soldiers and civilians in the outer city with high-yield crops.

In the winter, they are idle and idle, so they come to ask if they can grow corn, potatoes and sweet potatoes.

Chu Xujun is happy to see them conduct experiments in their own homes, even if it is just in the field in front of and behind the tent, and can buy a small piece of potato.

It is the attack of the Huns, and it is good that others can dig up a little food when they go here.

There was food and the general's wife, and everyone gradually became accustomed to the sound of the mountain behind them from time to time.

Some people say that it is the son of Xufeng who is taming the mountain god and learning skills.

Gradually, a complete story was formed.

Chu Xujun listened to it and admired the imagination of the ancients.

Princess Zhao Zifu's illness dragged on for a while before it got better.

But she didn't want to go to the outer city in person anymore, and the letter from Jingzhou hadn't arrived yet.

Zhao Zifu didn't give up, and she still kept inviting Chu Xujun to her mansion these days.

Chu Xujun receives posts every day, but he doesn't pay attention.

If she has the ability, Zhao Zifu came over by herself, she was busy every day and had no time.

Zhao Zifu slowly reacted, this woman from a small family not only has no knowledge, but what she said to accompany her often is also a lie.

She shouldn't have believed that there are people in the world who will only tell the truth.

Isn't it just a face?

It was useless to send a post, Zhao Zifu sent someone over this day to spread the word: "The eldest lady of the Chu family, the princess is invited. She said, if you don't go, your family won't necessarily be fine."

Chu Xujun stopped dividing the sweet potato in his hand, and was stunned, Yancheng still has the Chu family's family?
