This was the most severe blow to the Qing army since the war started. The dense crowds on the city walls became the best targets for the Red Turban Army's artillery fire. The earth-shaking screams could be heard everywhere, and blood tides were gushing everywhere.

This round of emergency fire caused at least twenty or thirty regiments, Qing soldiers, civilians and heroes to suffer casualties, and a solid lead bullet even knocked down three people one after another. Some Qing soldiers rolled on the ground in pain, making the final screams, and some Qing soldiers didn't even make a sound, and could only fall to the ground and make a low moan.

This is so terrible! There are many desperate people in the group of Renshi, who have now escaped from the city, threw down the bird guns in their hands, raised their guns and earth cannons, and shouted: "Get back! Go back!"

The psychological blow was more than the actual killing. Xu Muqian's face was pale. He didn't expect that the red scarf thief's cannon seemed to have become extremely powerful at once. Now only the 100th ones with the most courageous and stubborn Tuan Yong were left on the top of the city.

However, although this round of emergency fire caused considerable casualties to the Qing army, the Red Turban Army suffered a lot of losses. Two cannons exploded on the spot, causing one death and four injuries to the gunner. Even Liu Chang himself was almost hit by the broken pieces, and the remaining cannons did not dare to continue firing before cooling down.

Liu Chang felt ruthless in his heart: "Continue to press up, press up! Artillery, follow me, charge with bayonets! Cannons charge with bayonets! After fighting this battle, I will cast bronze cannons for you! Make bronze cannons, make bronze cannons!"

The reason why artillery made in the middle and late Qing Dynasty was easy to explode was that the Qing Dynasty's refining technology was quite backward, the furnace temperature was low, which led to the inability to purify the iron and contained a lot of miscellaneous music. The cast artillery pore bubbles could not withstand pressure when applied and were easily exploded. When Guan Tianpei inspected the explosion of the artillery, he found that "there were too much broken iron residue, the chamber was uneven and porous", and one of the holes was even "four bowls of water could be stored inside."

To fundamentally change this situation, in addition to purchasing new Western cannons, Liu Chang could only consider spending a lot of money to cast a few bronze cannons.

This is too luxurious, it is definitely a luxury to lose the family!

You should know that China is a country with quite a lack of copper resources. After the founding of the People's Republic of China, in order to save valuable copper resources, most of the People's Liberation Army's bullets used steel shells, and even the shell shells of the main artillery were gradually replaced by copper-clad steel shells.

In this time and space, copper coins are the main currency, and copper cannons are even more luxurious. Liu Chang loudly assured the artillery: "Isn't it a thousand eight hundred jin of copper coins? I can't buy foreign cannons, so let's cast copper cannons by ourselves!"

But Liu Chang also felt a pain in his heart. This was really a luxury and prodigal act.

You should know that in this era, the Hunan Army only spent 20,000 cents to build an improved mountain-splitting cannon, or only 20 cents to make a lifting gun. It costs 4,200 cents to make a lifting gun. As for the most commonly used bird gun, it only costs 1,200 cents.

But now, just for the material, a cannon will take out at least four or five hundred stag of copper coins, which is enough to create about twenty mountain-splitting cannons.

But if you don’t solve the problem of artillery, you won’t think of taking down the city. Liu Chang is also a helpless move.

As soon as he yelled, the morale of the artillery suddenly rose. They even asked at the risk of the artillery explosion: "Check, how much foreign medicine do you have sent? With your words, we promise to blow up Hai'an City!"

Although the danger of artillery explosion increased greatly after using granular gunpowder, the range and power increased by at least 10% or even more. Therefore, the artillery soldiers were very interested in this magical foreign gunpowder. Liu Chang replied to them: "As long as you can take down Hai'an City, you can hit as much as you want!"

The granular gunpowder he sent to the artillery now was not real foreign gunpowder, but homemade granular gunpowder by the captain of the battalion. Its quality is inferior to the real foreign gunpowder, but it is better that it can produce about ten kilograms every day and can be produced continuously.

After the foreigner Duncan came, he gave some advice. Xianna was preparing to increase the output on the existing basis, and he wanted to produce at least 30 kilograms of granular gunpowder every day. Therefore, Liu Chang also opened Haikou: "Don't worry, go and bomb, I brought dozens of barrels of foreign gunpowder!"

With Liu Chang's promise, the artillery team continued to move forward, and the Dragon Gun Shou was covering them. Platoon leader Zhu Dun, who was walking in the front, shouted to his soldiers: "It's going to be a killing! It's going to be a killing! It's all ready for me!"

Since he had not purchased the pistols used by the officers, he was now holding a firing gun in his hand and was the most ordinary rifle soldier: "Brothers, prepare to kill, wait for the regiment to come to the top of the city and release the guns together!"

Seeing the Red Turban Army's artillery team advanced more than ten steps, Xu Muqian shouted at the top of the city: "The Red Turban Thief is coming, the Red Turban Thief is coming, all of them are going to the city wall to block the Red Turban Thief!"

There are only 100 troupe braves on the city wall now, and there are many bird guns, and no one can control the local cannons. Therefore, he personally took a short till and grabbed the retreating troupe brave again: "As long as the red scarf thief is blocked, I, Xu Muqian, will produce a thousand acres of land!"

Although he was a super landlord with 100,000 acres of land, he took out 1,000 acres of land. Even though most of these fields were in Yueqing County, occupied by the Red Turban Army, it was even more costly than Liu Chang's bronze cannon. Therefore, when the retreating Tuan Yong heard Xu Muqian's reward, he rushed to the city again.

But before they even stood up their heels and set up guns, Liu Chang had already clenched his fists: "The Qing Yao Brigade is coming to the city, let me go! Let me go!"

This time, it was not just artillery that participated in the bombardment. The entire Dragon Gun and Flintlock rifle fired at the same time. Although most of the bullets either landed halfway or shot on the city wall, a small half of the rifle bullets roared up to the city, and together with the shells that shot on the city, a bloody tide formed.

This time, the troupe braves were much more slippery. When they saw the Red Turban Army stop moving and prepare to open fire, they immediately retreated, but were still beaten to death and injured more than ten people.

But even if Xu Muqian once again offered the temptation of 2,500 acres of land skin, no one was willing to act as a sent-off ghost.

Although the Red Turban Army's guns and cannons have been launched so far, only killing and injuring thirty or forty people, there are almost no people on the top of the city, and they are all hiding behind the hidden weapons cave. Such a rain of bullets and bullets is really terrifying.

Xu Muqian understood that the artillery team moved forward, but it was just a trick of the Red Turban Army to trick the group bravely on his side to the city and slaughter them. He couldn't help but think: "The red thief has made many poisonous plans, and I don't know what kind of tricks will be used next!"

He has no confidence in defending Hai'an City. Who told me that Liu Juehu, who is specializing in making a plan to make a big mistake?

"The Qing Yao team's more than 30 brave men have already left the South Gate and fled!"

When Liu Chang heard this news, he knew that these few rounds of guns and cannons were released, the confidence of the defenders had shook. He knew that today's three circumferences were just a trap, but he had to jump into the trap.

"It's time!" Liu Chang shouted at Sun Huzi: "Give some insights to the group heroes in the city!"

There are just some appetizers in front, this is the main meal!

This is the real strategy of losing your home.
