"This Liu Zeqing is so brave, he dares to come back." In the governor's yamen, Zhu Dadian was glaring at the beard and staring at the table angrily.

Two days ago, Liu Zeqing actually returned to Shandong with his troops.

In the sixth year, the bandits entered Henan. In September of the sixth year of Liu Zeqing, he was moved to Zhangde (Anyang), Henan. He first refused to go to the hospital, but the superiors urged him to the extreme. In the first seventh year, he saw that the bandits had already returned to Shaanxi, so he led his troops to Zhangde.

As a result, a few months later, he left the town with his troops and drove back to Heze, Shandong. Liu Zeqing was the most sloppy warlord in the late Ming Dynasty. He always followed the attitude of "Dragons and Forever". Why couldn't the Ming court move him? What he was best at in combat was naturally to make soy sauce.

Zhu Dadian had no good impression of Liu Zeqing. It was mainly because when Zhu Dadian commanded troops to suppress Kong Youde in the sixth year, Liu Qingze guarded the Water Gate. As a result, Liu Qingze was so scared that he did not dare to approach him when he met Kong Youde's bandits, and he was not familiar with firearms, which led to Kong Youde entering and leaving the Water Gate as if he was entering and leaving the home, and eventually allowed Kong Youde to escape and go out to the sea.

However, Liu Zeqing had more than 3,000 troops in his hands, and Zhu Dadian could only do anything and could not move!

In a bad mood, Zhu Dadian asked below: "What actions did Zhao Yan do in Huang County?"

"Report to the Lord, I'm very peaceful."

"Have the soldiers of Wendeng Camp been released?" Zhu Dadian continued to ask. Wu Anbang's useless material made Zhao Yan capture nearly two thousand people.

"Have been released to Ninghaizhou."

...

Zhao Yan was indeed quite at peace in Huang County and had no military transfer. The nearly two thousand prisoners were released after the road was built.

After all, they were also official troops, so Zhao Yan had no right to detain them again after he was pacified. The section from Huangxian to Zhaojiabao made these free laborers flat and wide, and the traffic problem was initially solved.

Those Shandong merchants were obviously very interested in the local law to make nitrogen. After all, no one would refuse the money-making things, and they all brought a technician back.

After more than a month of training, these technicians have mastered the technology from salt collection to purification, storage and transportation.

I believe that in the near future, this kind of local nitrogen-making workshop will be spread all over Shandong, and even urine can be sold for money, which will really generate income for the general public!

Zhao Yan has taught the craftsmen in the Military Weapon Bureau these days, and Zhao Yan selected a group of new cannons from the craftsmen.

At present, the technology of iron molding cannons has been overcome. The craftsmen of the Military Weapon Bureau have mastered this method, and the speed of cannons is naturally much faster than before.

Before the appearance of iron molding guns, people used mud molds to build artillery. Mud molds could only be used once and then they would be scrapped. Moreover, many honeycombs would appear in the barrel. If the process is not strict, it would be very easy to explode.

In addition, it is not easy to make clay molds, so it takes one or two months to make a clay mold. It is possible to get one that can be used. If it encounters rainy weather, it will take longer.

The technology of iron mold casting cannons appeared in the late Qing Dynasty, when Westerners had already used boring machines to build cannons.

With the technology of iron mold casting cannons, the production of cannons is undoubtedly much more convenient. However, the standard cannons have not been determined and a lot of experiments are required.

Zhao Yan invented the safety fuse and then told these craftsmen about artillery knowledge. The most important thing is to learn the unit of measurement, at least you must be able to understand Arabic numerals and understand the concepts of rice, decimeter, centimeter, and millimeter.

Some of the craftsmen in the artillery laboratory were just selected from various garrisons in Shandong. These craftsmen know the relevant techniques of casting cannons.

With the safety fuse, these craftsmen can experiment one by one according to different diameters, then record the data, and then select the most trial-making one from these data.

This time, Zhu Dadian asked him to select craftsmen, and most of them were shipwrecks. Most of these shipwrecks were recruited to Shandong to build warships when Yuan Keli was the governor of Denglai.

After the Kong Youde Rebellion, many of these shipwrecks disappeared, but hundreds of people could be found. These hundreds of shipwrecks are currently settled in Longkou Port.

Longkou Port is located in Huang County, which is a good port. Although Shandong implements a maritime ban, small-scale maritime smuggling still exists, but the amount is not as large as the southeast coast. Shandong officials often turn a blind eye. Mao Wenlong once detained the merchant ships that he went to trade with. Later, Yuan Chonghuan privately killed Mao Wenlong and returned the ship.

After these garrison craftsmen came to the Military Weapon Bureau, although they could not bring any advanced artillery, they were perfected in some technical details.

Among them is a craftsman named Lu Luan, who is good at creating a swarm. A swarm is an original version of rocket launcher. When the Ming army faced the enemy, it often launched tens of thousands of rockets at a time.

However, this kind of firearm is very lethal and can even be said to be less likely to kill people.

When Lu Luan mentioned this kind of swarm, he reminded Zhao Yan of a good weapon - the Gris Rocket. This kind of rocket is like the sky-storm cannon that he played during the Chinese New Year in later generations.

A small rocket tied a stick, took a little fire, and then flew out with a "swoosh". The Gris rocket is an enlarged version of the sky-storm cannon. It is equipped with shrapnel on its head and can cause range damage after explosion.

The manufacturing technology of this kind of rocket is not difficult, it is also very simple to launch, and its power is even better, especially in burning, which was still used by the British during the Opium War.

The disadvantage is that the landing point is relatively large, and it is generally only used for intensive bombing. The range is about 1,000 to 3,000. At the same time, if the rocket is equipped with an army, it will inevitably increase the amount of gunpowder.

Grenades also need to be developed. The technology of grenades is very simple, but there will be some requirements for ignition fuses. Throwing soldiers have appeared in the West, but when Zhao Yan studied the history of war, he found that these throwing soldiers generally do not have too much effect.

After all, the ignition method is a bit troublesome, and it is impossible to explode like in later generations. This primitive grenade is a relatively useless weapon in field battles.

Zhao Yan suddenly had an idea to equip the troops with Gris rockets, plus grenades, longbowmen, and artillery.

During the several formations between the two sides, musketeers first fired, then retreated to the back, some of them fought with swords in close combat, and some threw grenades from one to two rows behind. Some musketeers retreated to the back and set up rockets for support, longbow soldiers supported firepower behind, and artillerymen used howitzers to support firepower behind...

There are four types of fire support: grenades, longbows, rockets and artillery. The throwing soldiers are at the front, the longbows are located behind the horizontal team, and the artillery and rockets are at the end, forming a layered fire support. The grenades are blowing the nearest, and the longbows are extended to the back. The artillery is extended a little further, and the dense bombardment of rocket artillery...

With such a dense firepower network, the five-row deep horizontal lineups can completely block the impact of the cavalry. No matter how well the Qing cavalry was equipped, they were just flesh and blood. The words "a person with less than ten thousand people, and a person with more than ten thousand people will be invincible." They are just blowing out and bluffing people. Cooperating with the cruel massacre that has been heard, it really makes people feel scared.

Such an army has relatively high logistics supply requirements. After a war, it is estimated that a lot of arms will be consumed.

The most important thing is silver. It is obviously not a problem to rely on the glass mirror alone.
