Traveling through time and space to meet a replacement bride? But I’m a man!

The pulley block takes five days.

The two of them wandered around the county.

There are many small stalls on the street, selling authentic Yangchun noodles from the Central Plains.

"Brother Chen, that one looks authentic, would you like to try it?"

"all good."

The innkeeper saw the two men coming over with their horses and greeted them warmly, "Oh, two guests, please take a seat. Today we have a free bowl of tea. Come and see what we have to eat."

The shop sells plain noodles and wontons.”

"Two bowls of plain noodles and a bowl of wontons, please."

One bowl of noodles is definitely not enough for Chen Sanlin's appetite, and Xu Wenyan also wants to try the wontons.

"Okay, it will be ready soon."

The owner of this shop is a middle-aged man, and the chef seems to be his wife.

There was also a boy of about seven or eight years old in the room, blinking at Xu Wenyan.

My sister-in-law is a very good cook. She makes the noodles and wontons in advance and puts them into the pot very quickly.

"Hey, Boss, these few people came today. Isn't it a threat to kill us that the county magistrate asked us to come here?"

The shop owner was also helpless: "There is nothing we can do. Rich people have already spent money to avoid disasters. I have no money and can only be sent here to do business."

"Only three years. It will go by quickly."

Listening to their conversation, Xu Wenyan was very curious: "Brother, what do you mean by three years?"

“Oh, this is not a secret. Most of the people from the Central Plains who come here are driven here by the local county magistrate.

Originally, it was the merchants who were more likely to go out, but you also know that spending money can ward off disasters.”

"Anyone from the Central Plains who comes here will not be allowed to return within three years."

Xu Wenyan nodded. The government was being too heavy-handed.

The noodles tasted very good and Xu Wenyan liked it very much.

Then I went to Murati to buy some mutton.

Xu Wenyan asked if there were any piglets here, and Mulati told him that people here don't eat pigs.

After his reminder, Xu Wenyan finally remembered.

Even if you can buy pigs, it’s not a good idea to raise them here.

When he got home, it was already late. Xu Wenyan took the saltpeter ground by the workers and put them into a wooden barrel.

The wooden barrel was mostly filled with water.

Xu Wenyan wants to use solvent extraction method to purify the saltpeter in the saltpeter.

Saltpeter is easily soluble in water. When put into water, white frost will form on the surface as the water evaporates.

This is also the reason why white frost appears on the alkaline soil of the toilet wall tiles.

The white frost on top is nitrate.

After about half an hour, pour out the clear liquid on top and dry it in the sun, and you will get purified saltpeter.

It will be much easier to grind it later.

After putting the saltpeter into the water, Xu Wenyan started to cook dinner.

Luo Sanyuan ran to the stove and leaned against the door: "Lao Xu, the watermelons are growing small, each one is emerald green. I counted seven or eight on one watermelon."

Xu Wenyan kneaded the noodles and answered: "Are you referring to them?"

"Huh? Yes."

"That's it. This melon will fall if it's pointed at." Xu Wenyan said casually. This was what an old man in the village told him.

But it's really strange that Xu Wenyan also pointed at the melon when he was a child at his uncle's house.

The melon turned yellow the next day.

"Ah? No way!" Luo Sanyuan's eyes widened: "I pointed out several, no way?!"

Luo Sanyuan held his head, feeling a little guilty.

"Hey, I'll punish you by making you eat less at night."

When he was talking about such metaphysics, Xu Wenyan just teased him.

Put the mutton and four sheep's trotters into the pot and add the spice marinade.

While braising, Xu Wenyan kneads the dough into cakes and steams them in a steamer.

When the meat is braised, chop the meat, peppers and onions and mix them together.

Cut the pancake open and fill it with meat filling.

A traditional snack, Roujiamo, is ready.

Xu Wenyan has always had a question.

It's clearly a steamed bun with meat in it, why is it called roujiamo?

"Woo woo, Lao Xu, what did you make? It smells so good."

Luo Sanyuan had already smelled the smell coming from the kitchen, and because he had just pointed at the melons, all the watermelons would surely fall by tomorrow.

He was afraid that Xu Wenyan would be angry and didn't dare to enter the kitchen again.

I have been enduring like this until now.

But I couldn't bear it anymore at this time.

"You don't have dinner." Xu Wenyan joked.

"Woo woo woo, just let me have a bite."

Seeing his pitiful appearance, Xu Wenyan shook his head: "Eat, eat."

While eating, Xu Wenyan told Xiaoman about what was happening in the county.

Xiaoman, who is usually emotionally stable, couldn't help but snort coldly at this time.

That really seems to be their style.

As for Xiaoman's life experience, Xu Wenyan didn't know about it. Perhaps he was disappointed by the imperial court.

While they were talking, Luo Sanyuan had already made two roujiamo.

Chen Sanlin built three.

The two looked at each other, and Chen Sanlin looked at Luo Sanyuan teasingly.

Luo Sanyuan was not convinced that he could eat more than himself.

After quickly eating two, Chen Sanlin was no longer convinced.

Xu Wenyan made twelve pancakes. When he and Xiaoman came to their senses, there was no trace of the pancakes on the table.

"Luo Sanyuan! Brother Chen!"

"You're not allowed to have breakfast!"

......

Noon the next day.

Yesterday's saltpeter had also been filtered. Xu Wenyan took a roll of coarse paper and some powder mixed with saltpeter, carbon and sulfur, and walked away with the three of them.

Nitrate, disulfide and carbon.

This is the amount of molecular coefficients or mass ratio of the reactants in gunpowder.

S+2KNO3+3C=K2S＋N2↑＋3CO2↑

It contains about 10% sulfur, 15% carbon and 75% potassium nitrate.

This amount is not fixed, it is related to the concentration of the substance used, and it must be mixed in the right proportions to get the most powerful gunpowder.

The reaction principle is probably:

In a closed environment, gunpowder instantly produces a large amount of ammonia, carbon dioxide and other gases, the volume expands rapidly, the pressure increases suddenly, and a large amount of heat is released during the reaction.

This causes its temperature to rise rapidly, further expanding the gas and generating very strong thrust.

Then there was an explosion.

Xu Wenyan didn't know if there was any problem with his ratio, but he had to adjust it, he just hoped it would be quick.

Bury the first, second, and fifth portions of explosives under different stones.

Xu Wenyan and a few others ran away.

"I'll count to 123, and you pull the rope in turn."

Several people didn't know why they were so far away and connected by such an exaggerated length of rope.

But they believed Xu Wenyan.

"3...2...1——"
