In the past, Ji Jie tried to come up with the formula of gunpowder several times but failed, otherwise he would have used this thing on the battlefield.
Unexpectedly, when helping Zhao Qian make elixirs, she encountered an explosion. According to the little girl herself, she had forgotten to put in the most important medicinal ingredients in her excitement, otherwise it would never have exploded.
"Qian'er, don't study elixirs these days!" Ji Jie said seriously: "Just use these three things: charcoal, sulfur and saltpeter, grind them into powder finely, and mix them in different proportions. I want one
The most explosive formula!”
Gunpowder is a good thing. It directly promoted mankind's transition from cold weapons to hot weapons and changed the laws of war.
It seems that in history, Taoist priests who made alchemy accidentally discovered gunpowder. After hundreds of years of development, it was promoted. Ji Jie and Zhao Qian just advanced the time for gunpowder to appear.
…
Zhao Qian lived up to expectations and found the best ratio of gunpowder after many experiments.
Half a kilogram of gunpowder was put into a thick straw paper and rolled into a tube. Four gunpowder tubes were tied together and stuffed into the cracks in the rocks. Ji Jie lit the fuse with his own hands and ran away from a distance.
The little girl covered her ears. After a while, there was a loud "boom", rocks flew around, and a big rock was blown into pieces.
"Great, it's very powerful!" Ji Jie gave Zhao Qian a thumbs up.
Zhao Qian was very happy to receive Ji Jie's praise. This girl was completely focused on him.
"Um, mass production!" Ji Jie ordered on the spot: "Qian'er, you will be the person in charge of the gunpowder factory and produce according to the formula! There are two things to pay attention to. First, the formula must be kept secret; second, storage must be careful.
No open flames!"
"Qian'er has an order!"
Then, Ji Jie drew a few sketches and asked Ou Ming to make them out of fine steel. The forging supervisor quickly took out the samples.
The first one looks like a small cantaloupe, with walls six inches thick and covered with grooves four inches deep. It contains six ounces of gunpowder. After the explosion, it can form twenty-four shrapnel, with a killing range of five feet. It can be used against people wearing light armor.
Archers or light cavalry.
The second one is like a watermelon, containing six kilograms of gunpowder and 108 prefabricated fragments. It is thrown into the enemy's formation using a light trebuchet. Both the shock wave during the explosion and the fragments are very lethal, and the effective killing range is
At twenty feet, almost no armor can withstand it.
The last one is like a big winter melon. It is thrown by a large trebuchet. It contains fifteen kilograms of gunpowder and weighs nearly thirty kilograms after adding the shell. It is divided into two types: armor-piercing type and armor-piercing type. When the armor-piercing type explodes, it forms 360 pounds of gunpowder.
Ten prefabricated fragments have an effective killing range of thirty feet; the armor-piercing type has a smooth appearance and is specially designed to deal with enemy walls or gates.
Looking at the three "big killer weapons" in front of him, Ji Jie said with a smile: "Let's see who dares to take advantage of my city in the future. I will blow you all up to the sky!"
Ou Ming still doesn't understand what these things are used for, so he couldn't help but ask: "Your Majesty, these three things you asked me to make, one looks like a cantaloupe, one looks like a winter melon, and one looks like a watermelon, are they used as ritual utensils?"
Ritual utensils? Have you ever seen a ritual utensil made of iron? If not, it must be bronze.
Ji Jie pointed at the "watermelon" and said with a smile: "Ou Ming, think about it, what would happen if this thing flew into the enemy's formation and then exploded?"
Ou Ming's eyes lit up and he suddenly realized: "Your Majesty is wise, I understand!"
"Just understand. When we go back, we can mass-produce them. The more, the better!"
"yes!"
…
Since receiving the compensation from the Qin State, Ji Jie began to drastically renovate the royal city, demolishing old buildings, widening the streets, adding water supply and drainage systems, and expanding the city wall outward by one mile, thus expanding the area of the royal city.
More than twice.
The third son of King Nan of Zhou, Ji Yang, became the legal crown prince with the support of Ji Jie, the supervisor. However, whether he, the crown prince, can ascend the throne and become the emperor depends on whether Ji Jie is happy or not.
Ji Yang brought the few remaining Zhou veterans who had been screened several times by Ji Jie and moved into the palace. Grand Master Fei Cheng and his son Fei Mo were entrusted with important tasks. These two people have always been very good to Ji Jie. The most important thing is
It's because these two are not incompetent people who only know how to flatter.
Zhaocheng College was officially renamed Dazhou Taixue, specializing in cultivating various talents for Dazhou. After completing the studies, people were assigned to local areas to manage agriculture, commerce, water conservancy, military and other matters.
The prosperity of Zhaocheng attracted a large number of merchants. Here, merchants traded freely regardless of nationality. They traveled thousands of miles to bring special products from their own countries and exchange them for things from other countries. The northern nomads brought a large number of horses, cattle and sheep, especially
It is a fine horse and is very popular with the military of the seven countries. They rush to buy it.
Everything is so organized.
Just when everyone was silent in the joy of success, a sudden plague swept across the land of China.
The plague first appeared in the Chu State, and the Qin State, which was at war with it, could not avoid it. Then came the neighboring Wei State, and signs appeared in South Korea. Sima Heng immediately sent the news to Zhaocheng, reminding Ji Jie to take precautions in advance.
.
This plague was extremely rare. Those infected with the disease first had a fever, then felt cold all over, and then developed sores and pus. They died half a month later. Doctors from all over the world were helpless.
As long as one person is infected, the surrounding people will be infected quickly, and even the entire village and town. The plague spreads very quickly. Often a person is fine in the morning, but a large number of people are bedridden in the afternoon.
"It turned out to be an incurable plague!" Ji Jie knew that this was an era that lacked medical treatment and medicine, and people did not have a deep understanding of the plague. Many people did not regard the plague as a disease, but invited so-called great immortals.
Exorcise ghosts and subjugate demons, mislead others and yourself.
The spread of the plague is nothing more than air and water. Ji Jie took advantage of the fact that the epidemic had not yet been discovered in Dazhou, and immediately ordered the three cities to do a good job in sanitation and epidemic prevention, clearing away the piles of garbage, clearing blocked drainage ditches, and spreading spray on streets, factories, mines and other places.
When using quicklime powder, pay special attention to the corners.
The same applies to every village and town. Lime powder is not valuable, you can get it as much as you want.
Then, he took Zhao Qian to the border of Qin. He heard that people there had been infected with the plague, and a treatment must be found before the epidemic spread.
"After all the calculations, there was still a miscalculation in the end!" Ji Jie accompanied Zhao Qian in the carriage. Outside, Xiong Ba and Xiong Bi accompanied them with thirty strong warriors for protection.
They even forgot to set up a medical and health major in Taixue. Otherwise, they would not be so embarrassed in the face of the epidemic. Fortunately, they took Zhao Qian back. Otherwise, I really don’t know how to deal with it!
Qian'er hugged Ji Jie's arm and said: "It's normal to say everything is as close as possible! Let's get through the difficulties first, and then we can make long-term plans!"
Well, when the time comes, we can let this little girl Qian'er lead the lectures in the medical profession, and she will definitely be able to teach a large number of qualified doctors.
"Your Majesty, the road ahead is blocked by a big tree!" Xiong Ba said solemnly outside the car: "There are traces of ax chops on the tree trunk. It should be man-made. It is estimated that we have encountered bandits and robbed the road!"
