Times have changed. Since the emergence of cannons, tall city walls are no longer an effective means to block opponents' attacks. In Europe, tall castles have gradually become decorations, replaced by multiple structures arranged in terraced fields, with crossed firepower and low bastions, which use trenches and slope platforms to increase the difficulty of attackers.

It is precisely because of the arrangement of low fortifications and multiple structures that even a small, brick-and-wood-structured city of Yakshasa built by the Rakshasa people could stop the Qing army equipped with red barbarian cannons for more than a month. The Qing army could not conquer it, so they could only take the siege method. It besieged the Rakshasa soldiers for nearly a year before the Rakshasa people gave up and asked for peace. The Rakshasa people stationed at Yakshasa Castle only had 450 people, only three small cannons and more than three hundred mescorer guns.

Jaquesa Castle is piled up with earthen pieces, and brick-and-wood castles are built above the earthen platform. Because they are low, it is difficult for the Qing army's red cannons to hit the brick-and-wood castle above the earthen platform. Most of the shells fall on the earthen platform below the low castle. The energy is absorbed by the soil, making it difficult to collapse the brick-and-wood castle.

When Zheng Chenggong recovered Dongfan Island (Taiwan), he suffered a great loss in front of the Dutch bastion, and he could only take the siege to force the Dutch to admit defeat.

It can be said that direct artillery fired in this era could hardly destroy the low bastion, so the fortifications arranged by Zhao Peng from Lianpeng Mountain to Yanshan also adopted the structure of a simple bastion. With the current artillery of the Qing army, it can be said that it could hardly be conquered.

Of course, Zhao Peng himself had a way to deal with the bastion, which was the super-large caliber mortar. When the Ming army counterattacked in the future, if the Qing army built a large number of bastions to defend, the Ming army would carry two hundred pounds of mortars to attack. Two hundred pounds of mortars, would you ask if you were afraid?

Of course, the seaside corridors more than 20 miles wide could not be blocked. The project was too large, but only a serial fortress was needed to be built every distance. Before the Qing army destroyed the fortress, they did not dare to pass the passage in the middle. Forcibly passing the passage would be fired by artillery and muskets from the chain fortress, and the grain channels were easily cut off. Moreover, the ground of the middle passage had been dug into a bumpy pit, and the Qing army's cannons and supplies were difficult to pass.

Each chain of forts has a large mother fort and four sub-forts. Inside the large mother forts is a red cannon, two general cannons and two thousand kilograms of Franchise, and there are 1,200 soldiers stationed, including 400 bird gunners, 100 Lumi gunners, 100 turtledove gunners, 500 spearmen, and 100 gunners; each sub-fort is equipped with a five hundred kilograms of Franchise, four light 100 kilograms of Franchise, four tiger squat cannons, and another two hundred infantry guards are stationed, including 100 archers, 50 bird gunners, and 50 three-eyed gunners. The sub-fort lacks melee soldiers, so once a sub-fort is about to be unable to defend, two hundred defenders can retreat, and the firepower of the mother fort just covers the sub-fort.

Even if the Qing army climbed to the mother fort, they had to face various firearms from all directions. There were also city-guarding knives on the earth platform, which were moving resisting horses. Many people pushed knives, which could block the attacking Qing soldiers in the corner and allow the muskets behind to shoot calmly.

Although it was already April of the lunar calendar, the climate in Shanhaiguan during the Little Ice Age was still very cold. Zhao Peng held a big pickaxe he designed in his hand, took the lead in working sweating prospering, and brought a group of Shun Army soldiers to build fortifications.

The big pickaxe is not only a tool of labor, but also a good weapon for destroying armor. Use this tool by auxiliary soldiers to dig the ground and build fortifications. During war, the tip of the pickaxe hits the enemy's armor. No matter how many layers of armor you have, you can make a hole. The outer iron armor is chiseled through a hole like a can shell.

"Jiannu is here!" At this moment, someone suddenly screamed.

Zhao Peng climbed a high platform behind Tucheng, took out the Qianli Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Mi

Looking from the Qianli Mile Mile, we can see that these Qing soldiers were not wearing lightning rod helmets and foam nails and cotton armor on their heads, but green camp soldiers wearing blue and blue robes and cloth warm hats on their heads.

"General Zhao, can you use the Qianli Mile Mile Mile to use it?" Li Zicheng said.

Zhao Peng handed the Qianlijing to Li Zicheng. Li Zicheng took the Qianlijing, picked it up and looked at the Qing soldiers. He only looked at the Qianlijing in front of him and pointed at the Qing army advancing in the distance and asked, "It's weird, why did the Tartars change to this dress?"

"With the king, these are fake Tartars, green camps formed by Jiannu. They are all Han people, not real slaves!" Zhao Peng replied.

"I once heard that Jiannu had a Han army flag, all of whom were Han people. Why did another green camp appear?" Li Zicheng asked.

Zhao Peng patiently explained: "Although the Han army flag and the Green Camp are both Han people, the Han army flag is Han people who have already entered the Eight Banners, so they are no longer Han people. Strictly speaking, they are also Jiannu Tartars. As for the Green Camp, they are real fake Tartars, they are still Han people and have not entered the banner. The number of places in the Eight Banners of Jiannu is limited, so it is impossible for all surrendered Han people to enter the banner, so they formed a green camp. The newly surrendered Han army was incorporated into the green camp."

More than 10,000 Green Camp soldiers advanced toward the Shunjun defense line. The Green Camp soldiers at the front pushed the shield chariot full of macao, followed by Green Camp sword players holding shield waist knives, followed by teams of Green Camp commanders, and then Green Camp archers and bird gun soldiers. Behind the Green Camp soldiers were the Eight Banners Army wearing lightning rod helmets and foam nails and cotton armor.

Following the Green Camp soldiers were the Eight Banners dead soldiers wearing thick armor, followed by the Eight Banners archers and Han flag musket soldiers wearing light armor, and the Han flag cannon camp pushing cannons. The two wings of the Eight Banners formation are the Manchu Eight Banners heavy cavalry and Mongolian Eight Banners light cavalry. The brigade of Qing soldiers rolled in, and the flags of five colors of red, white, yellow, blue and green fluttered in the wind, with horns and drums rumbling.

In front of the brigade of Qing soldiers were teams of cavalry provocates. They roared, but kept approaching the Shun Army's defense line, and stopped outside the range of firearms and cannons. They shouted in a blunt Chinese above the earthen city, as if they were to let the Shun Army put down their weapons and surrender, and they could join the Qing army to conquer the world by surrendering.

This is the first time Zhao Peng has seen the Qing army after coming to this time and space. He knows that since he has come to this time and space, he cannot let the original tragedy in history happen again. This is his mission to this time and space.

Zhao Peng suddenly felt his blood boiling, and his whole body was filled with strength: "Good come! Whether it is a real Tartar or a fake Tartar, come! I'm waiting for you here!"

The Qing army's central army was in the center of the formation, and a large golden dragon flag on white background stood high. Under the banner, a Qing army general wearing a white lightning rod helmet and a white foam spike cotton armor was Dorgon. A Qing army general who was also wearing white was his younger brother Duoduo.

Duoduo picked up the Qianli Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles Miles

Kong Youde, beside him, also picked up the Qianlijing, looked forward to the line of defense, looked at it, and put down the Qianlijing: "Prince Yu, the thieves must not be able to build a city, and our army has arrived! Prince, our army must attack when the thieves have not yet established a foothold, and they will definitely defeat the enemy in one fell swoop! If the thieves reinforce the camp, it will be difficult to fight."
