Chen Jin was the governor of Liangguang and the governor of Guangdong, so he naturally had a lot of power in his hands. Although large-scale casting of iron ball shells is very iron-intensive. However, Guangdong in the Ming Dynasty was an important iron producing area, and Guangzhou Railway was an important source of iron in the Ming Dynasty. Guangdong Province, the annual output of iron can reach 5 million catties. Huizhou and Chaozhou, on the other hand, were famous iron smelting centers in the Ming Dynasty.

Therefore, as the governor of Liangguang and the governor of Guangdong, it was very simple for Chen Jin to obtain a large amount of iron materials. At the sound of an order, a large number of Guangzhou railways were transported to the front line in Liuzhou.

Of course, the front line was not idle. As many iron ball shells were cast, as many as they were hit. Even those short-barreled earthen cannons owned by the Ming Dynasty, craftsmen also cast iron ball cannonballs by the way, so that those earthen cannons could assist in shooting.

It's just that those earthen cannons are of different calibers. Even if sand casting is used, it is more troublesome to equip each earthen cannon with the right shells. After all, there is no strict unified standard for casting cannons in the Ming Dynasty, and it is all up to the craftsmen to play. Therefore, the cast cannons naturally have different calibers. Therefore, to equip the earthen cannon with cannonballs, the carpenter needs to make a wooden ball first, which just matches the caliber of the artillery. Then, using this wooden ball as the parent parent, the sand box is cast to obtain cannonballs.

This method of casting shells is very troublesome. Because, each earthen cannon needs to be equipped with a sand box for which to cast shells. Fortunately, green sand casting is relatively fast. As long as the wooden balls of the formwork are ready, they can be mass-produced immediately.

Moreover, at the beginning, although he also began to cast the shells of the Fran cannon, Chen Jin did not let the Fran cannon bombard the city wall, but asked the craftsmen to bury their heads in the cannonballs. On the contrary, it was the earthen cannons, which began to bombard the city wall after casting iron ball shells.

The reason for this is that Chen Jin believes that since the Fran cannon is more powerful, it should be put to the end to launch the final blow. If the early stage is too early and causes some damage to the wall, the enemy may take the opportunity to repair the wall. Therefore, Chen Jin simply let more than 20 earthen cannons bombard first, and then blasted the city wall first. Finally, let 10 more powerful Franc cannons be released, and the red slope city wall will be lifted in one fell swoop.

Of course, until then, the moat must be filled. Therefore, Chen Jin ordered the army to mobilize vans and transport sandbags to fill the moat.

The van cart has its own carriage, and the soldiers of the cart hide behind the carriage to push the cart, which can avoid the attack of the enemy army at the head of the city. Sandbags can also be placed in the carriage...... Before pushing the moat of the carriage lane, the soldiers took sandbags from the carriage and threw them into the moat......

By the time the craftsmen had forged 50,000 rounds of iron ball shells for 10 Furlong cannons, a section of the moat's main attack had already been filled. Moreover, the city walls were also bombarded by earthen cannons with iron ball shells.

And, coincidentally, after that it rained a torrential rain. The rainstorm came at a very good time. Coincidentally, the Ming army's earthen cannons blasted out many gaps on the outside of the city wall. Then, the torrential rain seeped into the hollow part of the inner part of the wall through the cracks. Then, the hollow part of the city wall is considered to be soaked in water......

If it is a normal city wall, there is no such problem. However, this wall is not normal......

The normal city walls are made of glutinous rice juice, brown sugar and lime mixed with a high-quality adhesive that binds the masonry together. As long as it is dry, it is resistant to water and impact in the future. But this section of the city wall is not made of glutinous rice juice, let alone mixed with brown sugar. It's made of non-stick indica rice juice and lime at all, and it's not strong enough at all. It was already devastated by artillery fire for a while, and then soaked in rain......

Then, the outside of the hollow city wall was directly loose. And the inner part, the brick joints were also blistered a little loose......

When the Franco's cannon reappeared in the rivers and lakes and began to bombard, the results immediately came out - the outer wall of the hollow city wall, which was already somewhat tattered, was blown through in half a day. The inner wall part, under the greeting of tens of thousands of iron ball shells, and the brick joints themselves were soaked loose, and then they could not withstand the shelling, and there was a gap......

It should be noted that ordinary front-loading bronze cannons generally have a lifespan of only about 1,000 shells, such as Napoleon guns. But the Furlong bronze cannon has a longer lifespan, why? Because the explosion chamber of the Furlong cannon took place inside the sub-gun. The impact on the bronze barrel was only an aftermath. Unlike the front-loading bronze cannon, because the explosion actually occurred at the bottom of the barrel, the barrel was directly subjected to a violent impact. Generally speaking, the barrel is fine, if the barrel is overheated, the copper barrel is easy to soften. With another explosion, the barrel is easily deformed......

But the Franc cannon is different, and the explosion of the Franc cannon is mainly in the sub-gun. The guns that Ma Lin gave to Daming were all steel guns made of steel from the iron and steel factory, which were much better quality than ordinary pig iron and wrought iron in this era. Naturally, the lifespan is also much longer. In addition, one cannon is replaced by 5 sub-guns in turn, so even if tens of thousands of shells are fired, 10 Furlong cannons can still be used......

(Note: In fact, the structure of the Furlong cannon is somewhat similar to that of later copper-cased rifles, which carry away most of the blast impact and heat, and the barrel life is naturally longer.) The barrel of a 56-and-a-half rifle made of ordinary 45-gauge carbon steel has a life of more than 10,000 rounds. This still takes into account the wear and tear of the rifling, and if it is a smoothbore gun, the life is higher...... Similarly, if the propellant is a less corrosive single-base gunpowder or even a weaker black powder, the life span can be further increased...... ）

After 50,000 rounds of iron ball shells were smashed, a gap finally opened in the city wall. Chen Jin was suddenly excited, and he hurriedly signaled Mao Rui, the commander-in-chief of the Liangguang Army, to send troops to attack.

So, Mao Rui hurriedly sent thousands of sword and shield soldiers to rush in through the gap that could only accommodate two people, despite the attack of the stones and bows and arrows of the Yao rebels at the head of the city......

But soon, the sword and shield soldiers were beaten out......

"What's going on?" Mao Rui asked the Qianhu who led the charge dissatisfiedly......

"Uncle Fuqiang, there are rattan armor soldiers in the city! The brothers rushed in and were beaten out by the enemy's rattan armor soldiers! ”

"What?" Chen Jin and Shen Rui were both taken aback.

"Romance of the Three Kingdoms" was written in the early Ming Dynasty, and there were many storytellers who talked about the Three Kingdoms in the Ming Dynasty. Therefore, Chen Jin and Mao Rui both knew what the rattan armor soldiers were. It's invulnerable and very difficult to deal with......

"Burning the vine armor soldiers?" Shen Rui suggested.

"Try it!" Chen Jin nodded.

Then, the Ming saber and shield soldiers replaced their single knives with torches and threw them into the gap, hoping to burn the enemy who blocked the gap, just like Zhuge Liang's rattan armor soldiers in "Romance of the Three Kingdoms" who defeated the barbarians in the southwest.

However, they miscalculated......

"Hmph, you want to 'burn the rattan armor soldiers'? I've been expecting this trick for a long time! At the head of the city, Zheng Yunhu proudly watched the Ming army's plan shattered.

The rattan armor soldiers in the city belong to the Yaomin troops under him. Zheng Yunhu has read books and listened to the Three Kingdoms Commentary, so he naturally knows the rattan armor soldiers.

Coincidentally, Zheng Yunhu and the other Yao people came from Datengxia, and they were most familiar with vines. According to Mr. Storyteller, Zheng Yunhu tried to make a batch of rattan armor with tough vines and tung oil. After years of experimentation, he finally made 800 pairs of rattan armor. Although it can't reach the level of invulnerability mentioned in the romance, it can still withstand most sword damage.

Therefore, in the face of the impact of the Ming saber and shield soldiers, the 800 Yao people vine armor soldiers successfully resisted and beat the Ming army back.

Moreover, Zheng Yunhu knows the weakness of the vine armor - that is, he is afraid of fire. So, before the city wall was breached, Zheng Yunhu arranged 800 rattan armor soldiers here. At the same time, a lot of buckets were moved, and a layer of cloth was put on the outside of the rattan armor soldiers, and the cloth clothes were soaked in water...... The rattan armor was covered with a wet cloth coat, and there was a bucket of water ready to extinguish the fire. Even if the Ming army threw torches in, it failed to make a contribution......

"Brother Xian is really clever! Ahaha! The big leader Huang Wenlong was also very happy when he saw this.

"The big boss, although the Ming army is temporarily blocked, after the truce at night, we still have to hurry up and plug this gap!"

"As it should be!"

……

However, they think too simply. Seeing this, Chen Jin said decisively:

"Fu Qiangbo, you choose hundreds of dead soldiers, as sword and shield soldiers, and rush in again......"

"But...... Your Excellency the Governor...... Those rattan armor soldiers? ”

"The old man told the musketeers to follow behind the sword and shield soldiers, and as soon as they entered the city, they shot the vine armor soldiers through the cracks of the sword and shield soldiers! The old man didn't believe it, those rattan armor could withstand the firecracker! ”

Shen Rui thought for a while, and his eyes suddenly lit up:

"What a plan the Governor! Even dozens of pounds of iron armor can't stop the muskets, let alone those vine-made rattan armor! ”

"Alright, you go and choose the dead warriors with great strength and martial arts. Remember, those men must use their strength to smash through a clearing so that the Musketeers have a place to stand! ”

"Yes!"

Then, Mao Rui selected 500 strong men, put on cotton armor lined with iron sheets, held a sword and shield, and rushed into the gap first......

After a bloody battle, these hundreds of people finally squeezed a gap under the sword of the Yao Coalition Army. Then a hundred arquebusiers took advantage of the situation and went into the city......

In order to cover the arquebusiers entering the city, Chen Jin also ordered the archers to concentrate on the enemy troops above the gap in the city wall, so that they did not dare to attack the musketeers. At the same time, another group of strong men, armed with hammers, also rushed forward and smashed the gap with a sledgehammer, making the gap bigger and bigger......

Soon, the arquebusiers entering the city found a gap in the crowd and began to target the vine armor soldiers who were engaged with the sword and shield soldiers......

Li Sanshui, commander of the arquebusiers, shouted:

"Don't move the sword and shield hand in front, otherwise it will be easy to be injured by mistake!"

Then, the sword and shield soldiers who were fighting with the Yaomin vine armor soldiers suddenly did not dare to move, but stood there mechanically to defend against the attack of the vine armor soldiers.

Just when the vine armor soldier thought he had the upper hand, a burst of gunfire suddenly sounded in the cracks of the people-"crackling-"

"Ahh......h

Because there are several rows of sword and shield soldiers from the arquebusiers, so close to each other, it is very easy to aim. Because, the arquebus in Marin Lane has a crosshair, which is very convenient to aim. So, the arquebusiers were all accurate. At least, there will be no "off-target". After all, the frontal area of a living person is so large. At such a close distance, it is difficult to "miss the target" and aim with a crosshair......

Dozens of grams of lead bullet smashed the rattan armor, and the rattan armor, which could resist the sword, was suddenly useless...... Anyone who is shot will either be killed or injured......

In the time of one cup of tea, half of the eight hundred vine armor soldiers were lost......

Because they were separated only by swords and shields, they were very close, and the arquebusiers were very accurate. A cup of tea, that is, ten minutes, but the musketeers have been shooting several rounds. When firing, the arquebusiers simply put their arquebuses on the shoulders of the sword and shield brothers in front of them in order to aim and shoot......

Although the vine armor soldiers are fierce in close combat, these sword and shield soldiers are also carefully selected strong men. It may be difficult to defeat these vine armor soldiers, but it is still no problem to withstand these vine armor soldiers. The rest of the time was for the arquebusiers to kill the vine armor soldiers......

The vine armor is not a ranged class, and they are helpless against the arquebusiers who hide behind them and release their cold guns......

In fact, unbeknownst to the vine armor soldiers, the arquebusiers were actually very afraid of the tide, and as long as they lifted the bucket on the ground and poured it over to wet the arquebus, the arquebusiers would be dumbfounded......

It's a pity that these soldiers of the Yao Rebel Army don't have this kind of awareness. They don't even know what an arquebus is, let alone think of a way to restrain it......

Therefore, under the cover of the sword and shield soldiers, in about two quarters of an hour, the rebel army's largest hole card vine armor soldiers were all wiped out......

Even the most elite vine armor soldiers were wiped out, and the rebel army of the Yao Coalition Army suddenly panicked, and their fighting spirit was seriously affected. Even Zheng Yunhu, the No. 2 person in the rebel army, was so angry that he vomited blood and fell into a coma. Before falling unconscious, Zheng Yunhu shouted, "My rattan armor soldier!" ”

On the other hand, the Ming army, after eliminating the rattan armor soldiers, was greatly boosted, and more Ming soldiers entered the city in one go......

In the era of cold weapons, morale is really mysterious. The Ming army, which was obviously a scumbag of the war, actually exploded in combat effectiveness after its morale was greatly boosted......

And the Yao coalition army in the city, because of the destruction of the vine armor soldiers, the morale has been seriously hit. Coupled with the number one think tank, Zheng Yunhu, vomited blood and fell into a coma, the titular leader Huang Wenlong suddenly panicked......

Then, in the street battle, the soldiers of the Ming army who were fighting five scum actually took the Yao coalition army to fight in a rare way......

After most of the day's bloody battle, the Ming army finally took control of most of Luorong County. By this time, it was already midnight......

Seeing that there was no hope of victory, Zheng Yunhu, who came to his senses, persuaded the big leader Huang Wenlong to break through from the north gate with the remnants of less than 3,000 soldiers. Then, in a circle, he fled south in the direction of Datengxia......

If they fled during the day, the Ming army would definitely be able to catch up with them if they had cavalry. But in the middle of the night, the Ming cavalry was not good at night fighting, so they let Huang Wenlong and Zheng Yunhu run away.

But in any case, Luorong County was finally recovered by the imperial court. Moreover, most of the rebel army was either annihilated or captured. Moreover, this is still a tough battle. Therefore, the Ming army was a complete victory.

As for the remnants of the rebel army, it is enough to chase after them with a large army......

The next day, the high-spirited Chen Jin hurriedly wrote a good news and prepared to send it to the capital.

The good news was divided into two copies, one was written by Chen Jin, who was the governor of Liangguang. The other copy was written by Mao Rui, who was the chief military officer of Liangguang.

Chen Jin is very much like boasting, but after all, he is a literati and wants to be embarrassed. So, he and Fu Qiang Bo Mao Rui discussed - let's praise each other......

In Chen Jin's good news, he praised the soldiers for their lives, and Mao Rui "led the troops well"......

In Mao Rui's good news, he boasted for Chen Jin, praising Chen Jin for "anticipating the enemy's opportunity" and "calculating no last resort...... Even the "purchase" of Fran cannons and arquebuses with the ghost was praised by Mao Rui as "extremely far-sighted". Because, these two weapons really shine in this battle......

In addition, Chen Jin's own recital also praised the Franco cannon and arquebus as "the important weapons of the country......

In this way, the Franc cannon and arquebus, as the things that had just been broken into the "cold palace" by Mao Cheng, the secretary of the Ministry of Rites, entered the field of vision of the Ming Dynasty as the "important weapon of the country......
