I was a famous teacher in ancient times

Chapter 459 There are traces to follow
Yang Xi looked serious, "This is very bad news."

Zhou Yu had already come to the table, spread out a blank piece of paper and drew a simple coastline, and pointed to the boundary of Ruizhou with a brush, "Xixuan controls less than 2000 sea troops, and logistics accounts for one-third of these troops. There are only more than [-] people who can fight."

Five thousand troops is the result of Xixuan's painstaking efforts over the past few years. However, naval training is not easy. When the ships do not have cannons, a naval battle is lost, and all the savings are wasted.

This also means that it will be difficult for Xixuan to develop its military strength in the sea.

Yang Xi pointed at the coastline near Nanzhou, "This is the dividing line. Once the northern pirates cross the line, they will pose a great threat to Xixuan."

They had to face the reality that Xixuan's naval force was no problem against small groups of pirates, even pirates from a single state could fight them, but they had no chance of winning against the pirates in the north who had been in business for an unknown number of years.

You know, there is King Jiang standing behind the pirates in Haizhou, but Xixuan was lucky and went south to discover King Jiang's secret.

Zhou Yu drew the land again, "Our country has a long coastline, and pirates have been rampant these years, especially the northern pirates are even more vicious. I'm afraid the northern pirates have already unified."

Yang Xi was also afraid, "It seems that the drought in the north is more serious than we expected."

The northern pirates have been forced to go south to rob, which shows how serious the shortage of food in the north is.

Zhou Yu looked at the northern location on the map, "This year, the harvest in the north is almost cut off. In addition to the changes in the northern tribes, King Jiang and Wang with different surnames are big food consumers, and they are in a hurry."

Yang Xi watched Zhou Yu continue to draw the map, and he had already drawn to the northwest area. If he continued to draw, he would be the grassland tribe. "Xixuan wants to use troops against Texas next year. If the pirate problem is not resolved, Xixuan will suffer from the enemy."

Xixuan can't withdraw from the coast that he laid down. Once he retreats, it will be difficult to get it back. Moreover, his own coastline has fallen into the hands of others. How can Xixuan sleep peacefully?
Yang Xi pulled the chair and sat down, thought for a while and said, "It seems that we are going to make gunpowder."

Zhou Yu hummed, "I still want to imitate some foreigner's firearms."

It is not difficult to imitate, he has already drawn the new smelting furnace, the only worry is the coal problem, but Xixuan also has confidence, who let Ruizhou have a mine and their husband and wife.

Yang Xi picked up a pen and drew the firearm, "Although there is not much room for improvement, it can be improved a little."

Foreigners' firearms have design aiming, but there is also room for improvement.

Zhou Yu said again: "You can also make some stone mines, as well as fire oil cannons."

In order to make their knowledge reasonable, Yang Xi and his wife have not stopped to read books, and there are still notes they took down on the bookshelf.

Although the methods of making various firearms are destroyed, their names and uses are recorded in the barracks, and even recorded firearm powers can be found.

Yang Xi was particularly impressed by several types of cannons, "You mean ceramic pots with gunpowder and poison inside?"

Zhou Yu nodded, "Originally, I wanted to procrastinate until the smelting furnace was built and slowly take it out for imitation. Now I can't procrastinate. I also want to make some spray tubes."

The principle of the spray barrel is simple. If you know fireworks, you will know the principle. The several spray barrels recorded in the book are all poisoned. Although the distance is not far, only about 30 meters, it is still a big killer when used well.

Yang Xi, "...the types you mentioned are all poisonous."

Zhou Yu spread his hands, "Currently we don't have enough raw materials to make gunpowder, but we have a lot of poisons. Here, I would like to thank Mr. Yu for making various kinds of poisons by mistake."

He took a sip of tea and continued: "At the same time, we can't be too monstrous. At present, it is most reasonable to imitate according to the data. According to the records, the spray gun is easy to imitate and has great lethality."

If the husband and wife act too monstrously, huh, then what they get will not be respected.

Zhou Yu continued: "We have successfully prepared a powerful gunpowder, which is already eye-catching."

Every step they take needs a basis to follow. Xixuan knows that no matter how busy they are, they will spare time to study every day. Although the imitation of gunpowder and spray canisters is shocking, with the characters they established long ago, Xixuan Knowing that they will only think that their brains are treasures.

If something is created out of nothing, it is not recorded in the barracks, and they make it in one step, huh, then it is not a treasure, but a monster.

Yang Xi counted the time from when Xixuan picked up the firearm to today, during which time they would reveal some research progress from time to time, and now the imitation will indeed not look too abrupt.

Yang Xi and his wife quickly finalized several imitation spray guns.

After the discussion was over, Yang Xi came to his senses, "Xixuan didn't come back, is he in the government office?"

Zhou Yu shook his head, "He's gone to the barracks, he can't leave Fucheng, he needs someone to command the troops on the island, he means to choose some cronies to go to the island."

Yang Xi took a stack of white paper and prepared to draw the spray canister based on the information, "I hope the northern pirates will not cross Nanzhou."

She said so, but she knew in her heart that if she went south for food, she would definitely cross Nanzhou.

Moreover, the north has long noticed the abnormality of the southern pirates, and will not let go of the opportunity to investigate.

For the Yang family, Yang Xi focused on the trivial matters of the Zhang family's female family members on the drawings. They ordered imitation spray guns, but imitation is not easy, it is not done based on the data, it has to be repeated Experiment and adjust the data.

Especially when poison is added to the spray barrel, the risk of experimentation is very high.

Yang Xi couldn't help drawing a gas mask on the paper, rubber, and I don't know if the Zhao family can bring the rubber back.

Yang Xi modified the gas mask a few times, and made a simple one without using rubber.

When Yang Xixuan returned home, it was already dark. Hearing Steward Xue said that her sister and brother-in-law were both in the study in the front yard, she turned around and went to the study.

The candles in the study room were brightly lit, many candles were lit, and the candlelight illuminated the room. Yang Xixuan's eyes adjusted for a while before entering the study room.

Steward Xue has carefully closed the door of the study. He doesn't know what happened. Since the two gentlemen came back, they haven't left the study. Today's dinner is also served in the study.

Zhou Yu signaled Xixuan to come over, and handed over the plan he made to Xixuan, "This is a plan based on the type of poison. You can decide if there is no problem."

Yang Xixuan was a little confused, what kind of poison, after taking it over for a closer look, Yang Xixuan was excited, "Brother-in-law, can you make it?"

He also arranged for people to study on the island according to the war records, but unfortunately the imitation did not have the power of the records. Instead, many casualties occurred due to the research.

Zhou Yu pointed to the thick stack of drawings on the table, "We still need to experiment, but we are [-]% sure."

In fact, there is a [-]% certainty, but it cannot be said that.

Yang Xixuan's eyes widened, and he flipped through the blueprints one by one. The blueprints not only marked the parts, but also recorded their uses, etc., and said, "You guys just put them on the desk so carelessly?"
