The weaving, iron-smelting and iron-making workshops built by Li Qi do not stop working in winter, and even in the cold winter months, there is still a loud noise and noise in the workshop, and the workers are still busy.

When these nobles of Jinyang are fine, they like to drill into the workshops of the royal manor and visit, and seem to think that as long as they study these machines thoroughly, they can find the secret of Li Qi's wealth. In this regard, Li Qi did not have the idea of despising the broom and cherishing himself, but hoped to promote the production methods of his own estate, and only by popularizing and popularizing these advanced production methods would Jindi and even China become richer.

A country will not be strong unless it gets rich first.

The current Jin Kingdom, although it seems to be strong on the surface, still relies on exploiting and scraping the people to maintain a huge army supply, and such a life cannot be maintained for a long time.

Winter should be a dormant day in a warm house.

The problem is that Yuan Xingqin, the privy envoy in charge of military affairs, did not want these subordinate generals to be born at all, and after the autumn harvest, he pulled Li Qi and personally watched the training of the forbidden army and the garrisons around Taiyuan. After Zhou Guangfu arrived in winter, the already serious bronchitis was committed again, and he hid in the hot spring villa of Longshou Mountain to recuperate, but handed over the task of inspecting the training of the Yanmen army of the Xin Dynasty to Li Qi, the emperor, to manage on his behalf.

After issuing new armor and weapons to the Tuntian army in Yunzhou and Shanbei, Yuan Xingqin believed that these Tuntian soldiers already had the potential to train into a strong army, and in the winter training plan he formulated, the original training volume was increased exponentially.

As a result, these soldiers who were the main force of Tuntian began to suffer.

It's just that Li Qi somewhat underestimated the endurance of the abject poor class of ordinary soldiers in this era, as long as they could provide sufficient food, these guys were driven by Yuan Ren, Fu Yanqing and An Xianqi and others, and insisted on hard training on the snow field every day.

For these situations, Li Qi doesn't care about them, anyway, his main purpose now is to make money, and his mind is not in the army. It's up to them to train these men hard during the slack time, as long as they don't cause trouble.

With the abundant food supply and the ability to replenish some meat from time to time, in fact, the physical fitness of the ordinary soldiers of the Taiyuan Garrison Army, the Yanmen Army, the Yunzhou Army and the Shanbei Army has improved a lot, but their physical strength is stronger than that of most of the elite soldiers in the old army, but Li Qi does not think that they now have the ability to confront the elite of the Southern Army.

Since more than 5,000 families from Hebei Province were recruited to settle in the Shanbei and Yunzhou areas in the summer, and because the newly reclaimed wasteland could not grow crops quickly, the huge investment made Li Qi, a large landowner, have little surplus food......

Li Qi is very busy, he has to worry about the renovation of the workshop, and he also has to plan the location for the capital water supervision to build water conservancy and open up wasteland next year, and in addition, Wuzhou in the north of the mountain will also build an iron-smelting workshop.

It is rare to have leisure, and I have to go to Jinyang Academy in Beiyuan to teach those teenagers in person.

When he walked into the classroom, he saw the teenagers whispering inside, and the classroom was buzzing like a beehive. Looking at the excited expressions of these young guards, they knew that their arrival made them very excited.

Li Qi was ready to surprise these young men, so he brought two packs of gunpowder.

Gunpowder was studied by Taoist priests during the Northern and Southern Dynasties, but it was used as an "elixir" for people to take, and many messy Chinese herbs were added to the formula. Li Qi didn't know how many people had died in this elixir, but he only knew that there were many well-known fools in history during the Eastern Jin Dynasty, such as Sima Rui......

Gunpowder had some applications in the military during the Tang Dynasty, but it was too powerful and was only used as a signal cannon.

This is mainly limited by the source and purity of the nitrate.

There are only some small nitrate mines in the Central Plains of China, the source of fire nitrate is mainly Sichuan nitrate, salt nitrate and soil nitrate, Sichuan nitrate comes from Zigong salt well, salt nitrate mainly comes from the salt pond in Shanxi, and the source of soil nitrate is also boiled with alkaline soil in toilets, corners and fields, and its purity is not high, so it has been limiting the power of gunpowder.

This made Li Qi very eager to acquire the large area of land that is now occupied by the Uighurs in Xizhou, knowing that the area around the Hami-Turpan Basin is the second largest nitrate resource in the world. Before the manufacture of synthetic ammonium, nitrate ore was basically the only source of raw materials for the large-scale production of industrial nitric acid.

Fortunately, there are some small nitrate mines in the northern Mongolian grassland and Shengzhou, and it is not very difficult to get nitrate. However, the main ingredient of this toxic "bitter salt" is sodium nitrate, which needs to be replaced with potassium nitrate in plant ash water.

As for the recipe for black powder, huh......

The students were taken to the playground to line up, and Shi Kang and two of his men took out a bamboo knot wrapped in oiled paper from the wooden box, dug a pit fifty meters away in front of the students, and buried it in the soil.

This guy was very bold, and after getting through the fright of the first experiment, he was very happy with the dangerous work of setting off artillery battles, and he had to do it himself to enjoy it.

Just performed in front of the students, the bamboo tube was filled with two catties of black powder, and the power was not too great.

After burying the firecrackers in the soil pit, Shi Dang pulled out the firecrackers, took a wormwood that had been lit from his subordinates, and waited for Li Qi's order to prepare to light the fire.

The two soldiers had already begun to run back, and Li Qi saw that they had run more than twenty meters, so he raised his right hand and signaled.

Shi Dang blew two mouthfuls on the wormwood with his mouth, and then aimed the fiery red fire at the fire, seeing that the fire was sparkling, this guy was still walking back unhurriedly, so angry that Li Qi wanted to rush over and give him a kick.

Seeing the sparkling fire burrowing into the earth, Shi Dang ran a few steps faster.

Rumble!

I only heard a loud noise, like a thunderbolt in the clear sky, only to see a stream of loess rising into the sky, and the fire was mixed with dense green smoke.

The students' eyes widened suddenly, and many of them were shocked......

Fortunately, Yuan Ren still had a certain effect on their military training, and no one was so frightened that they sat on the ground.

The same process was carried out again, and this time the students were much calmer, carefully observing Shi Kang's operation, as well as the effect of the firecracker explosion......

It's fresh, and it's absolutely amazing.

Li Qi was very satisfied with the performance of these students, and ordered the students to line up and circle around the two big craters that were blown up, and then waited for them to stand in line again, and then said to them loudly: "See, this is the power of science, what you have to do is to learn this knowledge, and then master and use this power!" ”
