Whether the Khitan is strong or not will be tested immediately.

Song Jiu is still working as a groundhog, and from time to time he runs to manage logistics, there is nothing to do, and Zhao Pu is ashamed of himself when it comes to multitasking.

The weather was getting hotter and hotter, and Guo Da and Hu Da were carrying bars not far away. Hu Da rode the big ash in the south of Shiling Guan, carrying a simple knife, and wanted to kill the enemy and make meritorious contributions. He Jiyun is not very easy to say, don't talk about killing the enemy, practice riding skills first. Zhilu said that this person was very important in Song Jiu's hands, and he also sent two guards to protect him, of course, he couldn't kill an enemy. But what if something happens to Song Jiu?

He Chengrui also asked Song Jiu.

Guo Dalai, He Chengrui can figure it out, that is Song Jiu's domestic servant, who specializes in being the bodyguard of the Song family, Hu Da is different, he not only manages the glaze workshop, but also manages the construction personnel of Hezhou for Song Jiu.

Song Jiu explained that he understood.

For what is the reuse of Hu Da, people are righteous and grateful, unlike many people who do not raise well and become white-eyed wolves, have prestige, have done business before, and have certain organizational experience. But it was still a coolie, clumsy and primitive organization, not like the army, the management was more strict, and it was brought over to let him see the world, and at the same time, there were still some box soldiers on the river island, these soldiers were all leftover box soldiers selected by the imperial court, old, weak, sick and disabled, or cowardly, but they were all soldiers, and there were a few thorns. Hu Da came to the front line, plated with a layer of gold, which could somewhat deter them.

Not only is he strong, but he is also a big fighter in the army, and there are not too many warriors with great strength, but he has great strength, one can't do two coming, two can't do three, Wu Song also let go.

Listening to Guo Da's chatter, Hu Da was very depressed.

Song Jiu smiled and continued to sit on the grass and calculate the data. At this time, Zhao Kuangyin came to him with his ministers. Giving together.

Zhao Kuangyin is cool, barefoot. The long-lost military life, it is estimated that he is quite happy in his heart. Song Jiu looked at his big feet. Zhao Kuangyin didn't care, and said: "The weather is too hot, I just went down to the river to wash." ”

With a wave of his hand, the eunuch came over to put on his shoes.

Then he asked, "When can I blow up the city walls?" ”

"At least the day after tomorrow."

"Try to hurry up, the Khitan will send a large army over again, this time there are many troops, once the country falls, I will be in a dilemma."

"Whoa."

The eunuch put on his shoes, and Zhao Kuangyin stood on the top of the hillside. Looking at the city, Lu Yuqing said: "From now on, the small city will not exist. ”

The tiger cannon is huge, the Taiyuan city was killed, within more than 200 meters, you can fire boulders at will, stone projectiles can reach more than 10 stones, if reduced to one stone, the farthest can reach more than 600 meters. But Taiyuan City is large, nearly nine miles long from north to south. It is nearly seven miles long from east to west. Trebuchets could not be fired under the city walls, and they also prevented the bows and arrows from being fired at the head of the city, which were generally placed a hundred paces away, and could be thrown up to five hundred meters into the city. It can produce damage at 400 meters. Therefore, Haizhou assassin Shi Sun Wan entered the siege of Fenzhou, first tested the fire with a tiger cannon, and fired a cannon to the center of the city. After a few artillery shots, Fenzhou surrendered. The Song Dynasty went out again to besiege Lanzhou. Zhao Wendu, the assassin of Lanzhou, ignored that his mother was still in Taiyuan City, and saw that the tiger cannon almost covered the whole city. I couldn't fight, so I surrendered the city. There are many examples of using trebuchets to force the enemy city to surrender in history, and the most famous is Hou Junji's destruction of Gaochang.

These examples have many flaws, the first is like the Song Dynasty, the formation of an absolute advantage in the city, surrounded, trebuchets slowly thrown, if you deal with the Khitan it may be dangerous, you are besieging the city, he mobilizes the army there, and fights with you outside the city, maybe the defenders in the city cooperate, inside and outside the attack, can you rest assured that you can throw it slowly.

Second, it is necessary to bring the skilled craftsmen of the army and make it on the spot, which is also very long, and if you want to form a dangerous quantity in the city, it may take several months to build.

The third is bulky.

The Tiger Cannon is different, it is also bulky, but it is much better than the original, the most important point is that it can be divided into parts, the huge cannon body can be disassembled in several parts, most of the places can be transported, quickly assembled, and immediately come in handy.

The city of Taiyuan is vast and cannot be covered. However, if you want to defend the city, under the attack of tiger artillery, the distance between the east and west, north and south of the city must not be less than 1,500 meters, so as to squeeze out a living space and ensure the safety of life. There are not many such cities.

If you are not afraid of foreign aid or internal assault, more than ninety percent of the small and medium-sized cities and forts, including the original Guan Kou Village, can be killed.

Moreover, unlike gunpowder, it involves complex casting techniques and steel, which is very difficult to imitate.

But this is Taiyuan City.

There are tiger cannons are not enough, everyone silently looked at the city, the city wall is full of rubble, there is hardly a complete house, not only stone bullets, but also bows and arrows, the accounts passed through Song Jiu's hands, just the Fu Yu crossbow fired out of the special crossbow reached more than 300,000 branches, more than 500,000 ordinary bows and arrows, Taiyuan City is still a city.

Sometimes Song Jiu looked at Taiyuan City, saw that the people felt miserable in their hearts, and thought of their tenacity, and felt hateful. If this fight continues, more people will die. There is a shortage of people everywhere, and it has not yet reached the age when human life is worthless!

Hurry up and end it.

But then Song Jiu understood what tragedy was.

The next day out of the trench, that is, the moat. In order to fill the two rivers, many soldiers died. But it doesn't work yet, it's just that the two winds valley wind and the Jin Temple water are filled, let them go south and east, and they have to be filled, otherwise there will be water in the trench when the rain falls, and the enemy can dig the river embankment at any time. Therefore, the people near Taiyuan were sent to dig and fill, this is your people, watch and shoot. But the following is not good for the father and mother, and the city cannot be broken, and the soldiers in the city still shoot. The arrows fired by the Song army were enough for them. The commander of the north is Cao Bin, who is not serious about killing, and sees that the people are pitiful, so he puts arrows and cannons below to cover. Or many people died, almost half of it was filled. Then a wooden stake was driven and used to make a landmark.

It must also be filled, Yang Ye dug the moat deeply, and it is impossible to make the tunnel dig deeper than the original moat.

Saying that it is useful, it doesn't seem to come in handy afterwards, saying that it is useless, but it is really useful, the biggest effect is time, and it has won more than ten days of precious time.

When I saw the new mud, I drove it to the stake, and then calculated it. This error is almost as small as less than 10 centimeters. People were digging underneath, and Song Jiu was only measuring the angle from a distance. Shadows, count it out. Among the ministers in the entourage, there were many civil servants, and one by one thought that they were gods, which was too powerful. Song Jiu shook his head and said, in another year or two, at least twenty of my students will be able to do it. It's strange if you don't understand.

I don't understand the city, but there are ways in the city, Song Jiu wants to dig tunnels, and Taiyuan City is the ancestor of digging tunnels. Especially Li Guangbi's battle, of course, the location is different, it is in Dongcheng District, that is, the abandoned city on the east bank of the Fenshui River. But the history of the city of Taiyuan.

Out of the trench, very close to the city walls, the battle began.

There are methods in the city, obviously digging trenches, but in fact, every night when it is dark, several tunnels are dug to the outside. It's all a feint. Outside the city, the tunnel is digging brightly, but the actual digging is a ramp, and some angles are still very large. Trenches are being dug in the city, and tunnels are actually being dug as well.

Wooden supports were built in it. The soldiers listened inside, and when the Song people came, they were silent. When it was time to pierce it, the spear stabbed down. He then hollowed out the dirt and went in heavily armed to assassinate him. Only a few escaped.

Cao Bin was furious. Tiger cannons were borrowed from the east and west battalions, and they poured them into the city, and took soldiers to suppress the fire of the city with ambush crossbows and the original crossbows, and sent soldiers to dig up the ground from above. However, the people inside had long since withdrawn and blocked up the earth. You can still dig it, but the Northern Han people have mastered all the directions of several tunnels, and they can stay in the city wall with a spear with peace of mind.

Also, there is an angle of almost more than 70 degrees, close to the wind valley river water gate, the Northern Han did not expect it, quietly approached. Song Jiu came to see Zhao Kuangyin with a map. He was also extremely hard, thinking that the Northern Han people were so strong, just this tunnel, about the Northern Han people couldn't think of it, so that the tunnel successfully passed under the city wall, and the gunpowder was also placed. Wait for a few more to be dug up, or blow them up first.

"We can't wait any longer," Zhao Kuangyin said.

Let's get started.

This day is the Dragon Boat Festival, and both sides have no festive atmosphere, the undercurrent is surging, and the morning glow is bloody. Song Jiu commanded, and the soldiers lit the fuse in the moisture-proof bamboo tube. This time Song Jiu made improvements again, not a coffin, but a cannon battle, the inspiration still comes from the artillery battle, some children are bold, holding the tail of a firecracker, and there is nothing to do for it, because there is a fire stuffed underneath. The gunpowder explodes, and the momentum moves forward. Of course, this is very dangerous, if the dirt underneath is not tightly stuffed, it will rush backwards and your hands will explode.

Therefore, it is a long cylindrical shape, and the outside is wrapped in two layers of iron sheets, so that the momentum of the air pressure is absolutely upward.

After a while, a loud bang was heard.

The tall Taiyuan city wall shook a few times, and suddenly fell down, and a large gap nearly ten meters wide appeared.

Many people in the city resented Yang Ye, thinking that Yang Ye had been defeated repeatedly and was beaten by the Song Dynasty.

Cao Bin shouted: "Rush." ”

Such a big gap appeared, no less than opening the city gate, but at this time the Northern Han soldiers actually organized, the Song army just arrived under the city wall, and the soldiers inside from the beginning of the panic to calm, and then to resist, and someone pushed out a small car, the front was fighting, and the back actually wrenched the car array. Then step by step, the car formation was pushed to the opening. The two armies began to fight fiercely across the chariot formations at the gap. In the blink of an eye, I don't know how many people died, and the blood stained the black earth red.

Then the common people also spontaneously organized themselves and rammed the stakes, which were originally made of sasswood, but now there is no need for sassholes, and there are stones in the city. Then the stones and earth were put in, and two hours later, a low wall appeared in the gap.

Hu Da opened his mouth wide in surprise and said, "That's okay." ”

When the city wall blew up, don't talk about Hu Da, even the Song soldiers also appeared sluggish for a moment, such a tall city wall fell down with only one sound, listening to the screams of the soldiers buried under the city wall, one by one stunned.

But how did the Northern Han people get organized.

Zhao Kuangyin also kept standing behind and watching, it was not that the Song soldiers were not brave, in these two hours, hundreds of soldiers were poured, and they rushed up one by one, but in the end they did not succeed. It was no longer interesting to rush again, and he ordered to stop the attack.

Lü Yuqing stood behind and was puzzled, as if the front of the city wall of Guankou Village fell, the rebels were dumbfounded, the Song army rushed in, and the battle ended. But it doesn't work in Taiyuan City.

Everyone thought of a few allusions, Tiandan's Jimo City, Yuanjia Caocao, Feng Wolf Juxu, Xuyi City, which won the only bright spot in Canghuang Beiguzhong, Shen Pu's Xuyi City, Zhang Xun Xu Yuan's Juyang City, and the damned Wei Xiaokuan Yubi City.

Thinking of Yubi City, everyone couldn't help but fight a cold war, the terrain is so similar, and there is Fenshui, but Yubi City is still in the south. The soldiers and horses are also very similar, the commanders are also similar, Gao Huan's ability is similar to Zhao Kuangyin, hundreds of thousands of soldiers and horses. The siege methods are even more varied, first water, Gao Huan cut off the Fenshui, not allowing drinking water in the city, Wei Xiaokuan used Tukezhi, digging a well in the city to draw water. Gao Huan used soil, built a high mountain outside the city, Wei Xiaokuan used Mu Kezhi, and added tall buildings in the city, the speed was faster, and it was always condescending. Gao Huan dug the tunnel, Wei Xiaokuan also used the practice of the Northern Han Dynasty, dug the dark ditch in advance, and the practice was even more damaged, and when he saw the hole coming out, there was firewood in it to ignite, and the wind was blown with a cowhide bag, and Gao Huan's hands were burned one by one. Gao Huan used gold and fully armored elite soldiers to attack Beicheng, but still suffered heavy casualties and did not succeed. Gao Huan used wood to make crashes like giants, and the giant curtains were put down on the city, which was soft and rigid, reducing the impact of the crash. Gao Huan used fire to burn the tent curtain with hemp rod anointing oil, Wei Xiaokuan used gold, tied the big knife to the long pole, hooked it down, hooked off the fireball, and in turn burned Gao Huan's men to death. Gao Huan dug tunnels again, built piles of wood, poured oil, burned wood and the city wall collapsed. Wei Xiaokuan used wood again, the gap fell in one place, and the fence blocked one place. Gao Huan was helpless, Yubi City was not captured, his subordinates folded more than 70,000 people, dug a huge pit to cover it, at that moment Gao Huan was vomiting blood, and then sang the famous "Song of Eile". Soon after, a generation of heroes died......

These battles had a far-reaching impact, An Lushan could not cross the Huai River, and the southeast supply came in a steady stream, and finally failed. The Northern Wei Dynasty could not cross the Yangtze River, and the north and south continued to split. The state of Qi then made a comeback. The Yuwen family eventually killed the Gao family.

But everyone still can't figure it out, who is Tian Dan, Zhang Xun Xu Yuan, Wei Xiaokuan, and Shen Pu in the city? (To be continued......)
