Kaifeng City is one of the important fulcrums on the Yellow River defense line.

However, it is located on a plain and has no danger to guard. It is easy to be surrounded and difficult to stick to.

At the end of June, Luoyang City.

After Gao Huan occupied Luoyang, he consciously moved various weapons workshops around Luoyang.

There is Mangshan in the north and Hulao in the east, and there are eight gates. It is not as dangerous as eastern Henan. The general soldiers’ workshops can have a stable production environment around Luoyang.

At this time, after discovering that it was difficult to cross the river, Gao Huan also trained a water camp in Mengjin, and while accompanying Gao Mingheng, Chen Yongfu and others to come to the weapons workshop outside Luoyang City.

With three years of development and the addition of the Song brothers, the various workshops under the control of the Weapon Bureau not only increased their output, but also put into mass production on several new things studied.

At this time, outside Luoyang City, there was a weapon workshop.

Gao Huan led Gao Mingheng and others to the workshop. Song Yingxing, Liu Tiejiang and others accompanied him, and introduced the situation of the workshop from time to time and the weapons produced...

"Supervisor, this is the transformed little thunder." Liu Blacksmith picked up a porcelain bottle that was only bigger than his fist. "Before, due to gunpowder formula and too thick iron shell, the requirements of the Supervisor were not met. After Lord Song came, he continued to improve the gunpowder formula and used this kind of porcelain bottle to make it so small."

Before the lack of artillery fire and flowering bullets? This powerful firepower support? Gao Huan has always hoped that the army could be equipped with miniaturized thunder and increased the offensive and defensive capabilities of individual soldiers.

However, due to the limited power of black gunpowder? After the thunder of the sky is small, the explosion basically loses its lethality? It is difficult to kill the enemy and kill the fragments.

After Gao Huan took it, he still felt a little big? It looks like a shot put? It is not convenient to carry and throw it hard. "Can you watch the shot?"

Song Yingxing said: "This is used to defend the city! The one who throws another!"

Blacksmith Liu hurriedly asked the craftsman to take out another type? A small thunder that was probably the size of a fist.

Gao Huan hurriedly took it over and observed it. He found that it was indeed much smaller, "Can you kill someone so small?"

Song Yingxing said: "I used to build a large amount because I put iron nails and stones in the shell to splash after explosion to kill the enemy. Although these iron nails can increase their power, they also occupy space for gunpowder. Now, the inside of this thunder is filled with gunpowder? After the explosion, they rely on the porcelain shell and iron shell to kill the enemy."

Gao Huan looked down and saw that the porcelain shell of this kind of porcelain mint is not smooth on the outside? And it is uneven? When he looked closely, it looked a bit like a sweet potato mint.

This made Gao Huan quite interested and asked: "Give me a few a try and give it to the high school chief and General Chen."

Gao Huan brought the two of them here this time, mainly to select a batch of firearms for Kaifeng City to be used for the city's defense.

At this moment, everyone moved under a high wall and tried to blow up the larger thunder.

At this time, Gao Huan and his group stood in the distance and saw craftsmen coming to rush to ten sheep, and also raised cotton armor for them, gathered under the city wall.

"The governor is about to begin!" Liu Blacksmith reminded.

Gao Huan saw the craftsmen running back under the city, and someone threw a large porcelain mine in the city.

With a loud "boom", white light burst out, thick smoke rolled, and the miserable hiss of the goat came.

Gao Huan, Gao Mingheng and others were all calmly looking at the explosion in front of them, because the explosion was not very severe and could not catch up with the thunder that had been equipped long ago.

After the explosion, a craftsman immediately came forward to check it out. Soon after, he came back and reported: "Report to the governor, three were killed and five were injured!"

Song Yingxing said: "The goat is short. If people gather together, it can kill and injure more than ten people. This kind of small thunder is mainly used to attack the enemy troops who are preparing to climb the city. Although its power is not as good as the thunder of the sky, its advantage is that it is cheap and can be thrown down by one person. However, porcelain thunder has a disadvantage. When throwing it down, it may break down and lose its power. If you don't care about the cost, the subordinates still recommend creating more iron-shelled thunder."

Gao Huan nodded slightly. Although this kind of porcelain mint is not very powerful and has defects, it is cheap. A pottery jar can be made with gunpowder, which is convenient for manufacturing, and is suitable for use in a war of attrition such as defending the city.

Gao Huan asked Liu Tiejiang: "How many such thunder have been produced?"

Liu Tiejiang said: "Reported to the governor, five thousand porcelains were produced and five hundred irons were produced."

Gao Huan asked again: "How much do they cost each?"

"Porcelain thunder costs about one tael of silver, and iron thunder costs two taels of silver. The main reason is that processing iron shells is more troublesome and time-consuming!" Liu Tiejiang said.

The firearm is indeed a expensive thing, but Gao Huan can afford this cost, and even if a thunder is exchanged for a Qing army, it is still cost-effective.

Gao Huan immediately said, "I will allocate you 200,000 taels to create 100,000 porcelain mines and 50,000 iron thunders for me."

But Liu Blacksmith shook his head, "Supervisor, this thing is too much gunpowder. The medicine used for a thunder is enough for bird gunners to fire forty or fifty guns. Now the gunpowder reserve is insufficient, and it is impossible to create so many small thunders in a short period of time."

Gao Huan wanted to give Gao Mingheng more firearms, but after hearing this, he turned to look at Gao Mingheng and said, "Zhongcheng, gunpowder cannot keep up. I can only give you one thousand porcelain mines and one hundred iron mines. However, I will send craftsmen to Kaifeng City to help you use local methods to make nitrogen to produce and manufacture these firearms in the city to defend the city."

There are hundreds of thousands of people in Kaifeng City, and they collect feces and make salt. They should be able to create hundreds of small thunders in a month.

Gao Mingheng and Chen Yongfu were both a little happy when they heard this. If there were too many thunders in the sky, the Qing army would set up a ladder and give them one, and the Qing army would find it difficult to break through Kaifeng City.

"It's great to be so real!" Gao Mingheng couldn't help but say gratefully.

Next, I tried to throw the small thunder that I threw, and the effect was very good.

Although it is not very powerful, throwing one into the crowd will definitely make the enemy confused, enhance the infantry's breakthrough defense and defense capabilities.

Gao Huan immediately gave Gao Mingheng 300 more to use for the purpose of competing with the Qing army for gaps after the city wall collapsed.

After Gao Huan distributed some of the firearms from the Arsenal to Gao Mingheng, Gao Mingheng and Chen Yongfu returned to Kaifeng City.

At the same time, several Zhongwu troops were assembled near Luoyang. Gao Huan sent Yang Chengzu to guard Zhengzhou, Liu Hui guarded Guide, Liu Qi guarded Xuzhou, Wu Ruyi guarded Chenzhou, and Yuan Shizhong was preparing to march to Shandong.

With Gao Huan's order, the departments went to the designated defense zone. After that, the first thing was to strengthen the city defense, and the second thing was to build granaries in the city so that the military government could transport enough grain for each city to consume for three months for reserve.

After the discussion, the battalion leaders and generals went to the sub-guards to prepare for the response. Liu Qi, Liu Hui, Yang Chengzu and other generals mobilized their troops and went to the defense zone.

Yuan Shizhong was going to Shandong, and finally left, Gao Huan personally saw him off.

Shandong was already in ruins under the destruction of the Qing army, and most prefectures and counties could not collect taxes. When the Zhongwu Army advanced to Shandong, it needed to carry both money, grain and military equipment.

At this time, more than 30,000 adapted Zhongwu Army soldiers pushed the cart and advanced eastward.

Gao Huan, Yuan Shizhong, Huang Long and Yuan Gui stood by the road and had a conversation. Gao Huan instructed: "When you arrive in Shandong, don't miss the big city. It is difficult to defend if you occupy it. Focus on the Yimeng Mountains. The first thing you do is to reclaim wasteland and plant sweet potatoes. Do you understand?"

"Don't worry, the general will know the importance of it!" Yuan Shizhong said with his fists.

Seeing this, Gao Huan nodded, then instructed Huang Long and Yuan Gui, and waved his hand: "Let's go!"

Everyone clasped their fists and pulled the reins of the horse, joined the brigade, headed towards Shandong.
