Liao Hua's military vision is still very unique, and he can see the great role of this general's cannon at a glance.

"If there are dozens of gates, it can easily break the enemy's gate and break the city wall."

Lu Bu nodded: "Yuan Jian is right. In fact, this is just a primary artillery, and its real lethality is very limited, but it can quickly destroy the enemy's psychological defense line. If hundreds of general artillery are at the same time, the defenders will easily collapse unless they are top-level strong troops."

Liao Hua took a breath of air conditioning: "This iron cannon uses so much iron, can we produce so much?"

Lu Bu smiled and said, "Of course, I can't produce that much. Now it's just an experiment. Only when the experiment is successful will it be mass-produced. Then use wood to make fake ones to scare people. True and fake ones will fight psychological warfare."

Liao Hua was quite interested in this, he was originally the material for leading troops.

Lu Bu appointed him as the general of Zhentian Camp. His level remained unchanged, his organization was not large, and he had only five thousand elite soldiers. Only a small number of them were artillery soldiers, and the others were shield soldiers, spearmen, and crossbow soldiers.

The fire rate of the cannon is very slow. After one firing, you need to clean the cannon chamber and cool it down. It takes about three to five minutes to open fire.

This requires strong protection. Otherwise, the artillery would have been knocked out by the enemy.

Cash the cannons while training.

The crouching tiger cannon was replaced by bamboo tubes, and the general cannon was replaced by tree trunks, and the exercises were coordinated by infantry and artillery.

During the battle, Danyang elite soldiers were used to cover the artillery. The artillery was lined up in front of the army. As they were fighting, the enemy rushed over. At this time, the Danyang infantry rushed forward to cover the artillery.

It's not that difficult, I became proficient in a few practices.

Cavalry is more troublesome, and horses are poorly immune to general artillery. The sound of shocking the world and the ghosts scares the horses very much. Therefore, in actual combat, cavalry and artillery must maintain a certain distance, and the one who truly covers artillery must be infantry.

Zhuge Liang proposed: "Use our crossbow as firepower to cover, push it on a small cart, or four soldiers are wearing crossbows. Once the artillery needs to be covered, the crossbows will be immediately supported, which can effectively deal with the enemy's heavy armored cavalry."

“It makes sense.”

The simulations were performed well in several experiments and could effectively defend against enemy attacks. The artillery soldiers used shield soldiers, spearmen and crossbow soldiers as cover troops, and the safety of Zhentian Battalion was guaranteed.

The cast artillery is actually not cast iron, but is made of iron, and is cast with sand as a mold.

Three general cannons can be poured in one day. The speed is nowhere to be seen, but the quality is average.

Due to the fact that the technicality of steel smelting is not too strong, the weight of the cannon is heavy. The 50 mm caliber capsized tiger cannon weighs 80 kilograms. Such a small cannon is only suitable for iron sand, and is most suitable for dealing with infantry and cavalry without armor.

The general's cannon with a mouth of 120 mm weighs 1,200 kilograms, and the cannon stand and wheel weigh 1,800 kilograms. It is necessary to be equipped with a strong mule. Such weight determines that you can only walk on the official road, various paths, and paths are not enough.

According to the theory, a 120-mm general cannon can hit five or six places, but Lu Bu is unwilling to add more cannon medicine. Why is this? Because in the entire Han Dynasty, looking at all the princes, one counts one. Only Lu Bu has artillery here, so there is no need to increase the range of the risk of blowing up the chamber. Once it leaves a shadow on the artillery, it will be very unfavorable to the later development.

In the valley, Liao Hua was patiently studying the problem of muzzle angle and landing point, but after research, it was found that the effect was not very great, because adjusting the angle was just to simply support the stick.

According to Lu Bu, this is the most basic artillery, and the focus is on psychological strikes. To put it bluntly, it is to scare the enemy.

The shells fell from the sky three or four miles away, and the enemy was already scared.

The main thing is to practice the proficiency of the gunner, clean the barrel, add cannon medicine, and add iron eggs.

Each process requires proficient training so that you can face the enemy without panic.

Thirty days later, a total of 100 creeping tiger cannons and fifty general cannons were cast.

Although there were fewer general artillery, the carpenter shop built three hundred fake general artillery, which looked very real and it was difficult to distinguish if it was not used.

Liao Hua was very attentive and led his soldiers to practice carefully. The Zhentian Camp has gradually become an army, after all, this is a team selected from veterans.

But this season is wrong, there is too much rainy season in July.

There has been a lot of heavy rain this year. The lifesaving boats prepared in the past few years came in handy. Where there was a flood, thousands of rescue troops rushed over.

There was no flood in Xuzhou, Qingzhou, Jizhou and Youzhou. However, water conservancy was overhauled and precautions were taken before the wheat harvest. Most of the impact was relatively minor and within the scope of control.

Moreover, Lu Bu was willing to pay money and food. Once floods occurred in various counties, he would dispatch food, clothing and other supplies as soon as possible.

Even if the people suffer from disasters, they will not have no way to survive.

However, Xuzhou has been making good news this year. First of all, fish farming has achieved great success. Carp, silver carp, and crucian carp, mainly in ponds and reservoirs, have achieved significant success. Fish fry can be cultivated manually.

Li Zhubo, the Fisheries Department, has been working all year round, and finally figured out the fish spawning rules.

Lu Bu came to inspect the fish fry cultivation base.

Master Li picked up a few silver carp fry.

"Lord, this is the silver carp seedlings we cultivated in late spring this year. Now they are two taels."

Lu Bu looked at the pond with these fish fryes, and the scale was quite large.

"Leave a small amount for fish pond feeding, and other places such as rivers, Weishan Lake."

"What is the lord who means putting the fry back into rivers and lakes?"

"Yes, a virtuous cycle is formed. People fish from rivers every year. They should be educated to enlarge the net and strictly prohibit the household network. However, the education of the people takes time. Our government should consider the long-term and consider that future generations have fish to eat and fish to catch them, so they must release fry every year."

According to Lu Bu's plan, each county must have a fish fry farm, with carp, silver carp and crucian carp manually hatching, and the fry will be cultured for several months before release.

"Okay, no problem. The hatching of these three types of fish has been gradually mastered, but the hatching of grass carp cannot be done."

It turns out that grass carp must lay eggs in the flowing water, and the requirements are strange.

Carp, especially Weishan Lake carp, is the best among fish. Frying fry is released every year, which can increase production in the long run. Although it seems to be a waste of money and food in the short term, in the long run, this is a good thing that will last forever.

He did it as soon as he wanted, and a large number of fish fry began to release, and millions of fish were released into the canal, Weishan Lake, and various river channels.
