Chapter 894: Blast Siege

"Sir, telegram. A telegram from the besieged Qin army." A communications lieutenant excitedly handed the telegram in his hand to Wang Jian.

"What?" Wang Jian didn't expect it either. So soon, the contact with the besieged Qin army was restored.

"Come here, let me see." Wang Jian immediately took the telegram to check it.

"Very good. Very good." Wang Jian said.

"Report to the king immediately." Wang Jian left as he said. He wanted to show the telegram to King Qin.

This time, the State of Qin resumed contact with the besieged Qin army. It was obtained by Qin State with its own technological advantages. If placed before. It is necessary to rely on soldiers to send orders from the besieged place at the cost of their lives. Sometimes it may not even be able to convey it. However, with the new technology. Restoring contact becomes much simpler. Especially after the telegraph and radio communication appeared. As long as the two parties have their own telegraphs, the communication will ensure smooth communication, because according to the current scientific level, Qi cannot understand the degree of not relying on people to convey the news. They were unable to organize a blockade network to block the communication of Qin Army news.

The Qi army did not know why the besieged Qin army brought something at the expense of an airship, but they stepped up their attack on Yandu.

"What's the situation?" A lieutenant Zhao Jun guarding the city wall patrolled back and forth.

"Nothing. The Qi Jun camp is still like that." Said a soldier from Zhao Jun who was in charge of patrolling and guarding guards.

"Be careful, don't be careless," the lieutenant said.

"It's the sir," the soldier said.

Finished. The lieutenant left.

"Be serious. It's impossible for us to defend such a large section of the wall." The soldier complained. Because Li Zuoche only sent a platoon of troops to defend the walls in four directions. Average down. There is less than one class on a section of the city wall. However, Li Zuoche temporarily transferred two platoons of Yan militiamen to assist them in defending the city wall.

Said to be defending the city wall, but in fact it was just standing guard. Because Li Zuoche didn't plan to defend the city wall. There is no plan to put the main force on the defense of the city wall. he thinks. Wall defense is undesirable. Because now the weapon is very different from before. Gunpowder weapons have changed many things. For example, the ability to destroy city walls is much greater than before.

As long as the yellow explosives manufactured by Qin State are in sufficient quantity, those reinforced concrete buildings can be blown into pieces. Even the kind of fortifications that were constructed, under the bombardment of Qin State's heavy artillery, could hardly escape.

While the offensive power has been strengthened, the defense has also been strengthened. Reinforced concrete fortifications can be made bigger and bigger. Defense ability is getting stronger and stronger. However, the capital of Yan State is still a previously built capital.

Before the construction of the capital he built, there was no reinforced concrete. Modern building materials such as cement. His building structure is not even masonry. It's the city-building technology that was commonly used before. Rammed earth structure. In the era of cold weapons, this structure was easy to build with rammed earth. During siege operations. Easy to repair. And the defense is relatively strong. Siege operations require a lot of manpower and force.

But with the development of science and technology. New siege weapons appeared. The power of gunpowder can destroy everything, coupled with the popularization of artillery and musket weapons, this kind of rammed-earth structure city has been difficult to defend against a large-scale attack by the other party. Especially in this situation now. Qi Jun is equipped with a large number of gunpowder weapons in his hands. If explosives are used intensively, this kind of rammed-earth structure is simply too low to stop the opponent's heavy blow.

Therefore, in the face of this situation, Li Zuoche chose a bold plan. Instead of consuming more manpower, it is better to hand over the wall to the opponent. Let the enemy take the initiative to enter the city. With the new buildings in the city, a large number of civil buildings have adopted new architectural structures. Masonry structure. Reinforced concrete building structure. The houses of these structures are much stronger than the walls made of rammed earth. In addition, the soldiers in their own hands are not fully trained, especially the Yan national soldiers, who have just learned to shoot. Some of them don't even have guns. Such a soldier without systematic training is not an opponent of the regular army at all. Therefore. Li Zuoche chose to fight street fighting, a new form of warfare never seen before.

Therefore, Li Zuoche can be regarded as abandoning the traditional tactics of the city wall defense war. He concentrated all his limited forces in important urban areas such as the railway station and the Qin Concession Area. As for other places. He gave up completely. Because he didn't plan to fight on the wall at all. He wants to let the enemy into the city. Entering the city is the real battle.

"Ding Ding." Just three feet below the ground not far away. The soldiers of the Qi army were digging shirtless.

With the popularity of iron farm tools. Infantry can use these farm tools to create more fortifications and siege machinery. But with the emergence of steel. Further development of engineering tools. The popularity of picks, shovels and other tools. Underground operations have become much easier. Plus the mining of underground minerals. All countries have begun to excavate shallow coal. The advancement of tools. Mining of mineral resources. As a result, there are a large number of excavation workers in all countries. Their specialty is digging. And this kind of excavation is naturally a new tactic.

"How far is it?" a Qi State engineer asked. Another engineer used a kerosene lamp to make measurements. They used a compass, goniometer, and various earthen tools, all of which were very similar to some engineering instruments made by Qin Guo.

"It's not far. It's only a dozen steps away." An engineer head said after the measurement.

"Dig." The Qi army soldiers said and started to do it.

The reason why the Qi army did not immediately launch an offensive. Instead, they stopped to build fortifications, which they prepared at the beginning.

Qi Jun generals think. It is impossible for a metropolis like Yandu to be without defenses, especially those artillery. machine gun. For the siege, it is a difficult problem to overcome. Therefore, they adopted the most earthly method. Dig trenches close to the opponent's wall. Shorten the offensive distance of the Qi army.

At the same time, a large amount of wasteland is generated. It just happens to be able to cover the new tactics of siege under the Qi army. Dig a way to blast the city.

Excavation often produces a lot of wasteland. Especially this kind of blasting will produce all kinds of waste soil. If these are not handled well, it is easy to be guarded by the opponent, so after the opponent is prepared. Then the offense is disadvantageous.

Therefore, Qi Jun adopted two combat plans. They dug trenches on the spot and slowly besieged Yandu. Simultaneous approach

Carry out large-scale underground operations for blasting. I have to say that Qi Jun is very lucky because of their thoughts. Li Zuoche had been around for a long time, and the first thing that Li Zuoche became interested in was the engineering arms independently established by the State of Qin. For this class. Li Zuoche has done in-depth research, and the engineers are more than just building roads. To get through traffic. At the same time, some engineering problems in siege operations can be solved quickly by engineers. Siege is not only on the surface, but also on the bottom. Because the source of engineers is not only construction workers, but also a large number of miners. The role of builders is construction, while the role of miners is blasting. The destructive effect is great. The emergence of this combat method quickly attracted the attention of Li Zuoche. It is this kind of attention that keeps him defending the city. He has always opposed this kind of defensive warfare arranged on the traditional front line. Instead, the defensive warfare of urban street fighting with crossed firepower.

It is for this reason that Li Zuoche reduced the observation of various abnormal phenomena outside the Qijun city, because he originally did not plan to defend the city wall. The city wall was only placed symbolically.

"Put explosives." A Qi State engineer ran out of the hole shirtless and shouted. Although it is winter, it is very hot inside. Engineers wearing clothes will soon get wet with sweat. This is why they are all shirtless.

"Quickly. Put the explosives." Then a Qi army officer commanded.

The soldiers of the Qi Army who were waiting outside the cave early carried the gunpowder kegs and carried them inside. The Qi Army used black gunpowder. This kind of gunpowder comes from the Kingdom of Chu, although there is a big gap with the gunpowder of the Qin Kingdom, mainly in terms of power. Qin's gunpowder is manufactured strictly in accordance with industrial proportions. At the same time, special particle technology and graphite brightening technology are used. Makes the power of black powder amazing. But the power of gunpowder made by Chu is much smaller than that. This is because the proportion of gunpowder manufactured in Chu State still does not meet the industrial proportion requirement, but the price of gunpowder manufactured in Chu State is cheap. Qi Guo has already spent a lot of money. They are almost unable to buy all kinds of weapons to fight. This cheap gunpowder. Become their first choice. As long as it can be fried, it makes no difference if it is a little bit more.

"Hurry up," the officer urged.

"Boom." A cry. A soldier hit the gunpowder keg.

"Looking for death. This is gunpowder. Not wine." The officer scolded. Immediately, the soldiers carefully put the gunpowder into the hole.

After two hours of busyness. Gunpowder was finally placed at the foot of Yandu's city wall. And this time. The sun is about to rise. A new day is about to begin.

"It's all out. Ignite," the officer shouted.

"Chichi," shouted as the officer shouted. A soldier lit the fuse with a torch in his hand. The fuse immediately made a scoffing sound. The soldiers who had finished the ignition turned their heads and ran away, fearing that they would get angry.

"Run." The soldiers ran out of the cave anxiously. They are afraid of affecting themselves.

"Chichi." The fuse burned quickly. The soldiers ran faster.

As for the following situation. The Qi army soldiers outside didn't know. they know. They are about to launch an attack. But now we need to wait for a signal.

"Boom." The earth trembled suddenly. A huge explosion sounded.
