Liaodong City!

Yuan Binzhi's eyes were red staring at Tang Jun in the distance, his eyes were bloodshot, as if he had pink eye, terrifying and even a little scary.

From the moment the Tang army attacked the city, he had not had a good night's sleep for five days and five nights, and he was really sleepy, so he only dared to hide in a safe place to take a nap and take a nap for an hour. As a veteran of a certain age, it is not easy to persevere.

Luo Shixin's style of play was too scoundrel, he did not send troops to suppress the territory, and only let the giant catapult bombard with flying rocks in the distance. Huge flying stones streaked across the sky, or smashed into the tower, smashing a small gap, or smashing into the crowd, crushing their defenders into pulp, and some even leaped over the towers and directly crushed the houses of the residents close to the city walls.

In the face of Datang's tactical play, Yuan Binzhi had no choice. Catapults are a sharp weapon for attack and defense, whether it is attacking and defending a city or attacking and defending a fortified barracks, it can play a decisive role. For the study of catapults, China began as early as the Spring and Autumn Period and the Warring States Period, when Xiang Yan of Chu State relied on a catapult to break 200,000 Qin troops and forced Li Xin, a Qin general with outstanding military achievements, to commit suicide. The original structure of the catapult was very simple, a huge lever, the long end was a leather holster or wooden basket loaded with stones, and the short end was tied to dozens of ropes, and the stones were thrown out using the simplest lever principle. Therefore, at that time, the catapult was not called a catapult, but simply called "throwing stones" and "flying stones", and later as human beings became more and more mature in their control of science and technology, they understood the principle of leverage more and more deeply, and "throwing stones" and "flying stones" were constantly improved.

Among them, the biggest change is the thunderbolt car invented by Cao Wei and Liu Ye during the Three Kingdoms period, which greatly changed the simple lever principle structure of the original catapult and relied on twisted ropes to generate power ejection. With a new model and a new power principle, the mobility, power, range and other performance of "Flying Stone" and "Flying Stone" have been greatly improved, and almost all aspects are far better than the old-fashioned "Throwing Stone" and "Flying Stone". "Throwing stones" and "flying stones" have also become powerful tools that can be moved. There are also many names, among which catapults are the most widely spread.

Goguryeo's catapults mainly came from the Northern and Southern Dynasties, when they talked about expanding their strength to Liaodong. Friendship with the Central Plains, greedy absorption. At that time, the Central Plains was in the period of extreme chaos during the Northern and Southern Dynasties. Not long after Fang Gang experienced the chaos of the Five Wants, various family of corrupt officials and wealthy princes had their own interests and did not care about the overall situation at all. In these turbulent times, everything is based on profit. There is nothing they can't do for the sake of profit, and the method of making catapults is certainly a state secret, but as long as there are enough benefits, Goguryeo can easily get their hands on it. Because of this, the catapults in Goguryeo's hands were from the period of the Northern and Southern Dynasties. A catapult derived from Cao Wei's Thunderbolt improvements.

With the unification of the Central Plains, catapults changed greatly in the Sui and Tang dynasties. Especially during the Wude period of the Tang Dynasty, when Li Shimin besieged Luoyang, the ordnance supervisor, who was proficient in ordnance construction, researched a new catapult. It is not simply relying on the power of leverage, but a large catapult that maximizes the power range of the catapult with manpower supplemented by the power of the lever twisting rope, and a catapult requires the strength of more than 200 people to control and operate.

This brand-new invention was a military secret in the Tang Dynasty, and the leaker was dealt with as treason.

At present, the Tang Dynasty is united in its heart, and there is no way for this powerful catapult to leak secrets, and Goguryeo has never heard of it. Not to mention how to deal with it.

For the artillery tactics of the Tang Dynasty, Yuan Bin, who was experienced in defending the city, was at a loss, and there was no way.

This technological disadvantage. It was not something that could be reversed by ingenuity and strategy, and Goguryeo could only be in a situation of being passively beaten.

Yuan Binzhi has not tried to resist more than once, he has more than once used giant trees to build a war tower on the city and used a thick rope net to try to intercept the flying stones, so that the flying stones smashed on the giant net, protecting the city wall and the soldiers on the city wall, but no matter how strong the giant net is, it can't resist the indestructible flying stones, and all defense methods finally end in failure.

Yuan Binzhi had to run between the four city gates to boost morale and appease the army. But he still noticed a steady decline in morale: he was very encouraged by this. However, he also had to admit that the Tang Army was far from being as simple and straightforward as the opponents it had encountered in the past, and only knew how to rely on the superiority of troops and national strength to attack. The group of enemies in front of him was impeccable in their use of tactics. Pushing them to their deaths step by step, they may not even have the slightest hope of victory.

Thinking about his grandson who died tragically. Thinking about the righteous son who treats him like a parent...... The aged Yuan Binzhi couldn't help but feel a faint pain.

"Old friend, I'm sorry for you. Maybe it won't be long before I'll come down and apologize to you personally! ”

Yuan Binzhi thought of what Hu Sizheng said to him before he left: "I don't want the child to be famous in the future, I just hope that he can be safe." In order not to cause you trouble, this kid is called Hu Xiegu. If I still have the surname of my Husi family, I am afraid that with Yang Guang's moody personality, if I know that I have a son who is alive and well, it will bring you unnecessary trouble. ”

Yuan Binzhi didn't have the intention of cultivating Hu Xiegu at first, but Hu Xiegu was self-taught and moved Yuan Binzhi with his own hard work. Yuan Bin's side just decided to promote and reuse, if it wasn't for the original decision, maybe Hu Xiegu wouldn't have died today.

Maybe it's a premonition of the end of his life, these days Yuan Binzhi is a little sentimental.

With the strength of the Liaodong city, even if the Tang Dynasty smashed it with a cannon stone for a month or two, there would be no problem, although the cannon stone was unsolvable, but the psychological pressure brought to them was extremely terrifying.

The Tang Dynasty as an attacker also got the gist of the siege, they were not brainless blindly throwing stones, at a critical time they would suddenly launch a wave of offensives, using siege turrets to forcibly storm the city gates, a careless will have the danger of breaking the city gates. The garrison had to be refreshed day and night, standing at the head of the city and being devastated by artillery fire.

Tired enemy, attack!

The Tang army was not just attacking the city, but attacking the heart.

"Bang!"

The huge flying stone smashed into the battlements near Yuanbinzhi, smashing a gap in the rammed earth wall of the battlements.

Gravel and dirt are splashed and dusty.

The small gravel was like a hidden weapon, shooting and injuring more than a dozen people in the vicinity.

"Big brother in soapy clothes?"

The surrounding soldiers shouted in panic one by one: Liaodong has fallen into a desperate situation, and Yuan Binzhi, a veteran who has repeatedly created miracles, is their only reliance. If Yuanbinzhi has three longs and two shorts, Liaodong really has no hope.

"Panic what!"

There was a loud shout from the dust made by the cannon stone, and the majesty of Yuan Bin calmly walked out of the flying dust, glanced at the gap lightly and laughed: "A piece of cannon stone, just smashed a small gap." My Liaodong city wall is high and thick, and I will bombard him for a month, and I will not be able to collapse our city wall if I use up the surrounding boulders. A month is enough time to wait for reinforcements to arrive. ”

With red eyes, Yuan Binzhi looked at Tang Ying in the distance: he has guarded Liaodong for most of his life, and he has never lacked the courage to live and die with Liaodong.

**********

The artillery stones of the Tang army have not been interrupted for a moment!

Tushan was also built with the efforts of the Tang army and the Goguryeo army.

This is where the real siege begins.

The crossbowmen and archers suppressed the Goguryeo defenders on the tower of the city with firepower on the earth hill with strong bows and crossbows, so that they could not successfully hinder the Tang army from attacking the city.

Under the city wall, all kinds of siege vehicles and rushing cars braved the rain and rocks to roll oil and stones, and fiercely hit the city gate and city wall.

The crossbow arrows of the Tang army and the siege soldiers cooperated with each other tacitly, and the offensive was extremely fierce. The Goguryeo soldiers also showed unusual tenacity under the command of Yuan Binzhi, a famous general, who successfully inspired the defenders of Liaodong City to survive in a desperate situation, and stubbornly repelled the attacks of the Tang army again and again.

On the eighteenth day of the siege of Liaodong City, the weather suddenly became abnormal.

The rare east wind howls, and if you walk in the wind, the wind will cut the exposed skin like a sharp blade, and there is a feeling of pain.

This sudden change changed the situation that Liaodong could not attack for a long time.

Zhang Shigui, who was in charge of attacking the east gate, faced this strong wind, and had an idea, gathered all the flammable items such as fire oil rockets in the general, ordered the crossbowmen to shoot rockets into the city, and ordered the catapults to throw the fire oil into the city as cannonballs.

The fire ignited the castle tower, and under the drive of the wind, it spread to the residential buildings in the city, and the fire became more and more vigorous, and it was out of control.

Zhang Shigui saw that the city tower had fallen into a sea of fire, and it was difficult to effectively launch a counterattack, so he personally led the siege soldiers to press up.

"Bang, bang, bang......"

The car slammed into the city gate again and again, and finally ......

The gates collapsed, and the huge gates opened a large hole that could only be passed through by one person.

The Tang army, who was not afraid of death, swarmed into the big cave, and Ma Wenju once again took the lead, passing through the cave and leading less than 100 people, facing the tide of the Goguryeo soldiers who came up like a tide, forcibly opened the city gate in the inner city and occupied the urn city at the east gate of Liaodong.

The Tang soldiers climbed the city wall along the urn city and fought a bloody battle with the Goguryeo defenders on the city tower.

The Goguryeo garrisons were armed with large shields and short soldiers, while the Tang army advanced step by step with spears.

At this moment, the Goguryeo garrison suddenly retreated without a fight, and a white flag was hoisted in the city.

Yuan Binzhi sent a messenger, saying that he was unwilling to surrender the city.

Zhang Shigui couldn't take the Dongcheng Tower for a while, and when he saw that Goguryeo was willing to surrender, he didn't know whether it was true or not, so he simply handed over the choice to Luo Shixin, postponed the offensive, and conveyed the situation to Luo Shixin, so that he, the commander of the three armies, could make a decision.

Luo Shixin's handsome tent was at the east gate where Zhang Shigui was in charge, and he had been paying attention to the results of this attack, and when he heard Yuan Bin's intention to surrender, he was stunned and couldn't help grinning: "The old guy fooled me as Yang Guanglai?"
