Great Zhou Tianzi

Previously, Ji Jie tried to come up with the gunpowder formula several times but failed, otherwise he would have used this thing on the battlefield long ago.

Unexpectedly, when helping Zhao Qian to make alchemy, there was an explosion. According to the little girl, she forgot to put the most important medicinal material in her excitement just now, otherwise it would never explode.

"Qian'er, don't study pills these days!" Ji Jie said solemnly: "Just use charcoal, sulfur and saltpeter, grind them into powder, and mix them in different proportions. I want one The most explosive formula!"

Gunpowder is a good thing. It directly promoted the transition of human beings 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, and it was only after hundreds of years of development that it was promoted. Ji Jie and Zhao Qian only advanced the time when gunpowder appeared.

……

Zhao Qian lived up to expectations and found the best ratio of gunpowder after many experiments.

Half a catty of gunpowder was put into a thick straw paper and rolled into a tube. The four gunpowder tubes were tied together and stuffed into a crack in the stone. Ji Jie lit the fuze with his own hands and ran away.

The little girl covered her ears, and after a while, there was a loud "boom", the stones flew around, and a big stone was blown into pieces.

"Great, very powerful!" Ji Jie gave Zhao Qian a thumbs up.

Zhao Qian was very happy to receive Ji Jie's praise, the girl was all focused on him.

"That, 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, the storage must be careful, Can't see the open fire!"

"Qian'er has orders!"

Then, Ji Jie drew a few sketches and asked Ou Ming to build it with fine steel, and the forging supervisor quickly took out the samples.

The first one looks like a small cantaloupe, with a wall thickness of six centimeters, and it is covered with deep grooves four quarters deep. It contains six taels of gunpowder. After the explosion, it can form 24 shrapnel, with a killing range of five feet. It can deal with bows and arrows wearing light armor. hand or light cavalry.

The second one is like a watermelon, containing six catties of gunpowder, and the prefabricated fragments have reached [-] pieces. They are thrown into the enemy's formation with a light trebuchet machine. Whether it is the shock wave or the fragments during the explosion, they are very lethal and have an effective killing range. Twenty feet, almost no armor can resist it.

The last one is like a big wax gourd, which is projected by a large catapult, loaded with 360 catties of gunpowder, and weighs nearly [-] catties after adding the shell. It is divided into two types: armor-piercing type and armor-piercing type. The fragments have an effective killing range of [-] feet; the armor-piercing type has a smooth appearance, and is designed to deal with the enemy's city walls or gates.

Looking at the three "big killer weapons" in front of him, Ji Jie said with a smile: "Who will dare to attack Lao Tzu's city in the future and blow you all to the sky!"

Ou Ming still doesn't understand what these things are for, so he couldn't help asking: "Your Majesty, the three things you asked me to make are like cantaloupe, winter melon, and watermelon. Are they used as ritual vessels?"

ritual vessel?Have you ever seen a sacrificial vessel made of iron, at least it must be a bronze one.

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 burst open?"

Ou Ming's eyes lit up, and he suddenly realized: "Your Majesty is wise, I understand!"

"It's good to understand, and mass-produce after returning home, the more the better!"

"Yes!"

……

Since receiving the compensation from the Qin State, Ji Jie began to renovate the royal city drastically, demolishing the old houses, widening the streets, increasing the water supply and drainage system, and expanding the city wall by one mile, so the area of ​​the royal city has also expanded twice as much.

The third son, Ji Yang, born to King Nan of Zhou, became the legal crown prince with the support of the supervisor Ji Jie, but whether he, the crown prince, can ascend the throne and become the emperor depends on whether Ji Jie is happy or not.

Ji Yang moved into the palace with the few old officials of the Great Zhou who had been screened out several times by Ji Jie. The grand master Fei Cheng and his son Fei Mo were entrusted with important tasks. These two people have always been very kind to Ji Jie. It's because the two of them are not incompetent people who only know how to flatter.

Zhaocheng College officially changed its name to Dazhou Taixue, which specialized in cultivating various talents for Dazhou. After completing their studies, they were assigned to local areas to manage agriculture, commerce, water conservancy, and military affairs.

The prosperity of Zhaocheng has attracted a large number of merchants. Here, merchants trade freely regardless of their nationality. They travel thousands of miles to bring their own special products and exchange them for other countries. The northern nomads bring a large number of horses, cattle and sheep, especially It is a horse, which is very popular with the military of the Seven Kingdoms, and they are vying to buy it.

Everything is so well organized.

Just when everyone was silent in the joy of success, a sudden plague swept the land of China.

The plague first appeared in the state of Chu, and the state of Qin, which was at war with it, could not be avoided. Then there were signs in the neighboring states of Wei and South Korea. Sima Heng immediately sent the news to Zhaocheng, reminding Ji Jie to take precautions in advance. .

This plague is extremely rare. People infected with the plague first developed a fever, then felt cold all over their bodies, and then developed sores and pus on their bodies. After half a month, they died. Doctors from all over the world were helpless.

As long as one person is infected, the surrounding people will be infected very quickly, even the entire village and the entire town. The plague spreads very quickly. Often, a person who exists is fine in the morning, and a large number of people are bedridden in the afternoon.

"It turned out to be a plague that can't be cured!" Ji Jie knows that this is an era of lack of medicine and medicine, and people's understanding of the plague is not deep enough. Many people don't regard the plague as a disease, but invite the so-called great fairy Exorcising ghosts and subduing demons, misleading others and oneself.

The way the plague spreads is nothing more than air and water. Taking advantage of the fact that the epidemic has not yet been discovered in Dazhou, Ji Jie immediately ordered the three cities to do a good job of sanitation and epidemic prevention, clear away the piled up garbage, clear the blocked drains, and sprinkle the streets, factories, mines and other places Quicklime powder, pay special attention to the corners.

The same is true for every village and town. Lime powder is worthless, and you can have as much as you want.

Then, he took Zhao Qian to the border of Qin State, where he heard that some people had been infected with the plague, and he had to find a cure before the epidemic spread.

"Thousands of calculations have been made, but in the end there is still a miscalculation!" Ji Jie sat in the carriage with Zhao Qian, while Xiong Ba and Xiong Ben led thirty strong warriors to protect them.

He even forgot to set up a medical and health major in Taixue, otherwise he wouldn't be so embarrassed in front of the epidemic. Fortunately, Zhao Qian was taken back, otherwise he really didn't know how to deal with it!

Qian'er hugged Ji Jie's arm and said: "The so-called one hundred secrets one sparse, this is normal! Let's get through the difficulties first, and then think about the long-term plan!"

Well, when the time comes, the little girl Qian'er can be allowed to lead the lecturer of the medical profession, and she will surely be able to teach a large number of qualified doctors.

"Your Majesty, the road ahead is blocked by a big tree!" Xiong Ba said in a low voice from outside the car: "There are traces of ax chopping on the tree trunk, it should be man-made, we probably encountered bandits robbing the road!"
