At this time, several bed crossbows in the city were pushed to the battlements, and then the long, large crossbow arrows were placed.

"Put!"

Ready, the operators of the crossbows on each bed shoot on their own.

The thick crossbow strings popped out, and the large crossbow arrows, which were slightly shorter than the spears, shot down the city with a low sound.

"Bang!"

Immediately, these crossbow arrows were shot into the Goguryeo archers under the city.

The crossbow bolt either hit the archer directly, and the spearhead pierced through it, shooting two people at a time, and then knocking down one piece.

Either hit the shield of the shield soldier, and the huge impact force directly knocked down the shield soldier, and also brought a small piece of it.

Of course, there are also arrows and crossbows that crash into the shield, and as soon as the shield is outside, the arrows and crossbows are shot into the Goguryeo soldiers hiding inside.

"Putting ......"

The power of the bed crossbow is extremely great, especially its deterrent power.

The Goguryeo soldiers under the city saw the crossbow arrows flying at them, and they were so frightened that they all lay on the ground to hide.

"Bed crossbow! Good stuff! ”

Although the Han army's bed crossbow dealt a great blow to the Goguryeo siege soldiers, it was not enough to shake the Goguryeo defeat or make the Goguryeo generals cower and withdraw.

So in Yi Yimo's eyes, it was full of blazing light.

As long as Seoul is captured, such a good thing will be their Great Goguryeo.

"Prince, the city gates are in an emergency!"

In just half an hour, there was a bloody battle above and below the city, the corpses continued, the blood flowed like a river, the battle was very fierce, and the other three began to ask Cheng Yu for help.

"Tell them that there are no reinforcements, continue to hold on resolutely, it's only been half an hour, give me all means, hold on until dark, after dark the enemy will not attack, hold today, tomorrow we will win."

Reinforcements, where did the reinforcements come from in the city, Cheng Yu could only reply to the other three gates.

There are 4,000 people in each gate, and they will keep watch for me for a day no matter what.

I can't hold it for a day, that's too weak.

If it is Donglai's old foundation, Cheng Yu believes that even if he fights for a day, no one will come to complain to him.

The old Yellow Turban Department is really fragile, and the concerns of the lord and everyone are correct.

If you want to get the number of Donglai, you must go through the elimination of the big war and train a strong army, so that the old Yellow Turban can really be reborn and grow.

The Yellow Turban Army is 100,000 strong, and if it is a normal reorganization, no matter how it is done, it will retain 30,000 or 40,000 people in the end, and according to the establishment of Donglai, this is six or seven captains.

The promoted generals directly accounted for half of the officer quotas.

These people are one: they don't have strong personal martial arts, at most they are second-rate or third-rate and half-rate in Donglai, and they are barely okay as deputy generals.

Second, there is no real ability to command the troops, and there is a general lack of cultural knowledge, which is not in line with the purpose of strengthening the army in Donglai in the future.

Therefore, these people not only can't make Donglai stronger, but they don't handle it properly, which will make them resentful and bring bad Donglai's atmosphere.

This is one of the reasons why Xu Ding has not dealt with them all along.

After all, if it is not handled properly, it will bury hidden dangers for the future growth of Donglai.

The first generation of generals may generally be brave, but in the future, with the progress of science and technology, the comprehensive type will occupy the mainstream.

Thinking of these, Cheng Yu thought of Xu Ding again.

I guess the letter was sent to Weiyuan Island, or it was sent to Donglai.

After receiving the letter, Xu Ding would definitely bring troops over to support.

So before the reinforcements, before the arrival of Xu Ding, he had to hold the city.

This is not only related to the personal safety of the people of Seoul and himself, but also to the safety of Zhang Ning and others in the old Jinquan City, as well as the safety of Manzhong and others in Hanze City.

Because Cheng Yu understands very well that the enemy now mainly wants to eat Seoul, and may fight against other cities, but the main thing is to besiege, once Seoul falls, this is a morale blow to the Han army in other cities, and at the same time, the enemy can also allocate more troops to deal with other cities.

At that time, they will all be destroyed.

Therefore, Cheng Yu must defend the city, even if it is only until tomorrow.

Therefore, Cheng Yu was glad in his heart, glad that the enemy had a huge plan and attacked Hancheng first, instead of besieging Tian Feng and Man Zhong and others with an army of two or three hundred thousand first.

Otherwise, no Han army can stop it.

The battle at the North Gate is still fierce!

The bed crossbow continued to be activated, and one after another crossbow arrows were fired into the Goguryeo army, and the Han army in the city was constantly shot and injured, and then carried down by the people for treatment.

Stones, wood, arrows, and fish oil were also constantly transported by the people.

The Goguryeo people, who were constantly climbing up, fought with the spearmen and swords of the Han army at the head of the city.

Fortunately, the north gate was okay, there was Xu Chu, he took his personal guards to kill the Goguryeo people who went to the city again and again, and several times the Goguryeo people rushed to several generals, but they were still hacked to death by him, and the corpses were thrown down the city to be used as weapons.

One after another, the ladders were knocked down and fell, and the Goguryeo people lifted them up again and again on the walls.

An hour and a half passed, and the other three gates also exhausted all kinds of methods, held on, and kept the city to the death.

However, the consumption of fish oil is huge.

Because every time the people of these three gates felt that they could not bear it, they pushed oil barrels under the city, and the oil barrels smashed down the city, and they were torn apart, and countless fish oil rolled out.

Then the defenders of the city would release rockets, ignite the city, form a sea of fire, interrupt the attacking Goguryeo, disrupt their siege rhythm, and then organize troops to clear the Goguryeo soldiers who climbed up.

In this way, they kept the city again and again.

However, as a result, the fish oil transported from Weiyuan Island and Donglai is almost exhausted.

Fish oil is a strategically scarce commodity.

Because the territory of Xu Ding is basically close to the sea and makes a living for fishing and hunting, Weiyuan Island catches a lot of marine fish, and then gets a large amount of fish oil stored from them.

Of course, these fish oils are not refined for consumption, so the extraction is relatively easy, and the relative nature is simpler than using tea oil tung oil.

But once the war starts, it can't withstand such large-scale consumption!

It's not distressing to sell Yetian, Cheng Yu is probably slandering these bastards in his heart.

It doesn't matter if the fish oil is gone, just defend the city.

Looking at the sky, there was still a period of time before it was dark, he gritted his teeth and said: "Notify the three city gates, you can reduce the use of fish oil, and at the same time increase the number of crossbows used, and ...... Let's use a trebuchet! ”

That's right, there is also a weapon in the city to defend the city.

Trebuchet!

This is also what Cheng Yu asked Weiyuan's craftsmen to do before he arrived, and some of them were barely Huang Chengyan's apprentices, and the young ones were selected to go to Donglai Academy or follow Huang Chengyan to learn mechanical knowledge.

Then he followed Huang Yueying to make a few trebuchets.

After familiarizing yourself with the process, you returned to the Machinery Department.

Then he followed Cheng Yu to Seoul.

After arriving in Seoul, they have been quietly arranged to be protected by the army and secretly build trebuchets.

So even the traitor traitor Yang Dengzhi didn't know, after all, the construction of the bed crossbow was public, and the eyes of Yang Dengzhi and others were attracted here.

Who would have thought that Cheng Yu secretly made a trebuchet.

You must know that even now, few people know about the offensive and defensive equipment of trebuchets.

Ordinary people have long forgotten this long-range offensive and defensive equipment that once originated in the Warring States.

Not only did the other three cities immediately launch the last sharp weapon to defend the city, but Cheng Yu also pushed out the trebuchet here, and even one was lifted out of the city gate.

That's right, the parts were disassembled, shipped up, and assembled in the gatehouse.

The rows of trebuchets in the open space of the inner city were also placed, moving as far forward as possible.

After all, this thing doesn't have a very long range.

A 30-kilogram stone projectile has an average range of about kilograms, and a typical stone projectile has a range of about 40-70 meters.

However, this is before the normal unimproved ones.

These trebuchets in Seoul are made of steel produced on Waiwondo, and many parts are used to increase the range of the original trebuchet.

So the firing range has increased by ten to fifteen percent.

It seems to have increased by an average of more than 10 meters, but the lethality and effect are amazing.

I saw that the trebuchets were loaded with stone bullets.

With the commander shouting, the flag waved.

Four or five big men pulled the rope in unison.

The linkage machine drives the other end, and uses the force of the rod to shoot the stone bullet belt in the groove.

More than a dozen stone bullets flew from the city wall and fell outside the city.

The Goguryeo soldiers who were rushing inadvertently looked up and found more than a dozen black dots flying towards them.

I haven't figured out the situation yet.

I only heard a whistling overhead, and then the ground shook, and a group of people fell behind me, or forward.

Some people were directly hit on the body and turned into flesh, and some had their arms or feet broken.

The effect is very good, much more powerful than the bed crossbow, each arrow of the bed crossbow down, at most three or four people killed, in order to deter the enemy to interrupt the rhythm of the attack.

But the trebuchet, the stone projectile that flies over, it is a piece kill, and if it hits one and continues to roll, it will hurt one piece until the inertial kinetic energy is all released.

It can be said that its staying power is longer, but the disadvantage is also obvious, it has no clear goal.

Even if it is the same plane, the impact point is not fixed every time.

Very casual and casual.

"Put!"

This trebuchet placed on the city is also projectile out, this one is pedaled by manpower, which can be used to adjust the range distance according to the number of people, and generally four people step hard at the same time, using the force used by the foot to carry out linkage amplification transmission to the pole, and the stone projectile is projected out by using the pole rod.

This trebuchet is more accurate and generally low, making it suitable for use in places with narrow distances such as those on the city walls.

With a "buzz" sound, a stone projectile flew out and smashed into the archer formation of Goguryeo under the city, directly killing and wounding one piece.

Then the second batch of stone bullets in the city was also fired, and the attacking Goguryeo people were killed, wounded.

The trebuchet is stronger than the bed crossbow in terms of lethality and deterrence, and in the face of the constantly flying big stones, the Goguryeo people are really afraid this time.

In the rear of Goguryeo, Yi Yimo and a group of Goguryeo generals also had solemn faces and wrinkled eyebrows.

The Han army also used a defensive weapon that could throw boulders out of the city wind, and its power and killing were too great.

It's a weapon they've never seen before, let alone heard of.

"Damn, what the hell is this, why didn't the Yuan family tell us." A Goguryeo general scolded indignantly.

The others looked at Yuan Chun one after another.

Yuan Chun also looked stupid.

It was not unusual for the bed crossbow to come out, and he didn't know what this stone-throwing weapon was.

"King! We don't know about this thing, it's the hinterland of my big man, and we haven't heard of it. Yuan Chun is a little unlearned, so he can only explain forcibly.

He really hadn't heard of trebuchets, and Xu Ding's troops hadn't used them before.

He didn't read history books, so naturally he didn't know that Huaxia had fought with trebuchets during the Warring States period.

Yi Yimo watched as the Goguryeo soldiers were hit and swept away, and the Goguryeo people under the city were so dense that even if they wanted to, there was nowhere to hide.

So he glanced at a more elegant minister beside him, this minister was called Yan Liu, and he was very respected by Yi Yimo.

After taking the throne, Yiyimu was determined to reform the chaotic political situation and ordered officials to recommend new talents. Many people have recommended Yan Liu. However, Yan Liu recommended a better talent than himself.

Yiyimu listened to his words and appointed Ebasu, who was a farmer, as the prime minister, to rectify the country and increase the national strength of Goguryeo.

Therefore, his two powerful ministers, Yibasu, stayed in the national capital, and Yan Liu brought out the staff officers of the army.

Yan Liu stood up and persuaded: "King! The enemy's equipment is too sophisticated, and our army will be killed and wounded for a long time, and it is hopeless to capture the city today, so it is better to retreat and rest, it is best to make the same equipment, so that there is a chance of winning the city! ”

The power of the trebuchet was too strong, and the Goguryeo attack team was too dense, just a few hits, no less than 1,000 people were killed and wounded, and in addition to the losses of the siege in the previous hour and a half, Goguryeo lost 20,000 troops today.

This number exceeded expectations.

"Withdraw your troops!" Yi Yimo got down the stairs and took advantage of the situation to give the order for Mingjin to withdraw his troops.

All the Goguryeo people were relieved, and in the face of the stone bullets flying from the city, the siege troops of Simen were under great pressure, and at this time they received orders and immediately withdrew from the battle.

The Han army in the city also breathed a sigh of relief.

The trebuchet is powerful, and it repels the enemy as soon as it strikes.

Looking at the sky, it was still early in the day, Cheng Yu didn't have much joy, and in the face of the soldiers who were celebrating and cheering, he just muttered softly: "There will be a hard battle tomorrow!" ”

Back in the barracks, Yi Yimo said to Yuan Chun: "Yuan Gongzi, this is a sharp weapon made by you Han people, tell me how to deal with it!" ”

Yuan Chun didn't even know what it was, how to reply to him, and he had been vague.

Qin Xiaodao, who was on the side: "Son, it's better to contact the shadows in the city, sneak into the city at night, one to find out the news, if the two can destroy their equipment......"

Yuan Chunli's eyes flashed, and he said to Yi Yimo: "King, this plan is feasible. ”

"Alright! You should contact the inner response in the city as soon as possible to find out what kind of artifact is in Seoul, it is so powerful, if it can be destroyed, it will be destroyed, and if it can't be destroyed, you must get a way to build it. "Yi Yi Mo is not stupid, he has seen the power and movement of the trebuchet during the day, and naturally knows that this thing is estimated to be not only used to defend the city, but also to siege the city.

A stone of this size can be thrown out of the city, and it can also be thrown into the city to attack the city defenses.

With this thing, it will be more efficient to attack the cities of the Han people in the future, and many Goguryeo soldiers can be killed.

After all, Goguryeo has a limited population, and 18,000 people die in every battle, so how can it expand and develop.
