The army slowly approached the Jinan city wall, the artillery that had arrived at the position took the lead in firing, and more than 20 red-coated cannons carried by the army fired at the same time, and its sound resounded through the sky, and the cannonballs smashed down the city wall, and the entire city wall seemed to be shaking!

Although there are a lot of artillery in the city of Jinan, but most of them are ordinary artillery, most of the artillery of the Qing army was originally taken from the hands of the Ming army, in the southern expedition of the Qing army carried hundreds of red-coated cannons carried by the two roads were lost, and the remaining red-coated cannons are under the control of the Eight Banners, and the green battalion soldiers have no power. Therefore, in the face of the bombardment of the Ming army's red-coated artillery, the defenders of Jinan were basically in a situation where they could only be beaten and could not fight back. Where is the range of ordinary artillery as long as that of a redcoat cannon?

If there is enough time, these dozens of red-coated cannons alone can blast through the city walls of Jinan! But Li Yi knew that there was no time at all.

Hong Chengchou took more than 100,000 green battalion soldiers to hide in Zhangqiu, which is more than 100 miles away from Jinan, and he can reach Jinan in two or three days. If the Ming army wants to capture the city of Jinan, it will take two or three days.

Li Yi stood quietly on a high command car, directing the movements of the whole army, and the banner of "Qi Wang Chen" behind him was waving in the wind, because he was ordered to act under the banner of Qi King Chen Yue.

The first wave of attacking Ming troops, under the command of Li Yulin, had approached a mile from the city wall and was making preparations before the attack. For the Ming army under Chen Yue, although there have been countless battles, there are not too many truly tragic siege battles. Since Li Yi waved his army into Shandong, he has also conquered dozens of cities, but most of those cities have either been abandoned by the Qing army on their own initiative, or the defenders have surrendered, and so far they have not experienced a real hard battle.

However, there are many defenders of the city, and naturally there is some experience in how to siege the city. Although he had agreed with Hu Maozhen, Hu Maozhen would open the city gate to welcome the army into the city. But if he didn't put great pressure on Jinan City, how could Li Chengdong believe in the determination of the Ming army to attack the city, and how could Hu Maozhen find the opportunity to open the city gate?

Therefore, Li Yi was not ambiguous about the preparation for the siege, and in the two days since he arrived in Jinan, the craftsmen of the Ordnance Department have not stopped for a moment, building all kinds of siege equipment day and night.

It was completely in a posture of attack.

In fact, in the bottom of his heart, Li Yi also regarded this siege as a real attack, so as to practice the skills of the army's attack.

Jinan has internal responses, and there is no big problem in capturing the city. However, in the future, there will be many cities that are unwilling to surrender, and the Northern Expeditionary Army needs to conquer them one by one. In Li Yi's view, it is necessary to practice siege skills.

Even, in order not to leak the news of the internal response, in order not to make the soldiers slack, the news of Hu Maozhen's meeting anyway Li Yi did not convey it to the middle-level officers and ordinary soldiers except for a few senior generals.

Therefore, the vast majority of officers and soldiers do not know about the internal affairs in the city. Most people also regard this siege as a real siege, and this is the effect that Li Yi wants to achieve.

Before the appearance of the red-coated cannons, there were actually several ways to siege the city, such as hitting the door with a car crashing into the door, digging tunnels into the city, digging tunnels to dig down the city walls, piling up soil and the city walls and then storming, and then the ladder to attack the city.

After thousands of years of war, the defenders also have-for-tat methods on how to crack the siege, so the final siege battle will eventually become the most cruel and easiest way to storm the ladder, and this kind of siege war is the most cruel for the besieging side.

Because it is necessary to climb the ladder to attack the city wall two or three zhang high, it needs to pay several times or even ten times the sacrifice of the defenders, so the strength of the besieging side of the siege of the city must be more than ten times that of the defenders before it can be captured.

And if the defenders have sufficient troops and sufficient food and grass, it is normal for a battle to last a year and a half. In another time and space, Yan Yingyuan relied on tens of thousands of ordinary people in Jiangyin to defend Jiangyin for eighty days, you must know that he is facing hundreds of thousands of Qing troops, and he is basically ordinary people in his hands. In the end, the Qing army could only rely on red-coated cannons to break through the city wall of Jiangyin, which led to the defeat of Jiangyin.

Therefore, it can also be seen that the red-coated cannon is important for the siege of the city, thousands of catties of red-coated cannons, the projectile weighs one or twenty catties, and it is shot from a place several miles away, and the power is enough to open the mountain and split the stones, which is actually a sharp weapon for breaking through the city wall.

Therefore, with the red-coated cannons, the siege is much simpler, as long as there are enough red-coated cannons, it is not a problem to blast through the city walls. The Qing army in another time and space relied on the sharp weapon of the red-coated cannon captured from the Ming army, and the city was invincible.

Yangzhou and Jiangyin, whenever the defenders resolutely resisted the city, they relied on the red-coated cannons to blast the city walls, and then attacked the city and slaughtered, relying on the slaughter to break the will of the Han people to resist, so that other cities did not dare to resist.

Therefore, if you want to break through Jinan City, it is the most convenient means to break through the city wall with red-coated cannons, and you don't need to pay a great sacrifice like the cloud ladder attack.

But it takes at least two or three days of repeated bombardment for the red-clothed cannon to break through the city wall, and for Li Yi, he has another means that can quickly collapse the city wall, which needs to be tested through actual combat.

Therefore, whether it is a red-coated cannon, a ladder, a shield car, or a Lu public car, these are all smokescreens used to cover this new siege method.

Holding the clairvoyant mirror and looking over, he saw that Li Yulin was already preparing to attack the city according to his own deployment.

More than 5,000 musketeers were the first to reach the moat and fired at the city in three waves. At every moment, hundreds of projectiles were fired at the head of the city, and on this section of the city wall that was a hundred feet wide, the defenders did not dare to show their heads at all.

After the musketeers, there were more than 3,000 crossbowmen, who shot crossbows from the sky and rained arrows onto the city walls to make up for the lack of musket projectiles.

In order to launch an offensive, Li Yi sent half of his long-range troops under the city walls, with the aim of suppressing the defenders of the city.

"Damn, Ming Jun is going crazy!" Several iron shields protected Li Chengdong's up and down, left and right, and looking through the gaps in the shields, the green battalion soldiers at the head of the city were beaten like duckweed in the rain, one by one, everyone dared to emerge from the battlement, and no one dared to try to fight back at the city.

The brave Green Battalion soldiers were dead, and the walls were littered with corpses. The most odious thing is that the Ming army also mobilized a large number of archers in addition to the fire gun shooting, and the arrows fell from the sky over the battlements of the city wall, specifically shooting overhead, forcing the green battalion soldiers to stick their bodies under the battlements to avoid the rain of arrows of the Ming army.

"With such a strong offensive, where does it look like the inside should be combined with the outside, the Ming army is clearly going to attack!" Li Chengdong thought secretly.
