The counterweight trebuchet is a siege weapon that makes full use of the principle of leverage. On the basis of the original trebuchet, Ma Chao listened to the advice of Publius, used special tough animal tendons as ropes, and added a noose plate to further charge power. As a result, the power and distance of the Ma family trebuchet to throw stones were far ahead of the Han Dynasty.

No way, as a descendant of the Romans, Publius is proficient in trebuchets: who let the Romans play this, earlier than us Chinese?

The trebuchet continued to relent, and the shooters had adjusted their angles after the first round of test tosses. At the same time, the remaining thirty trebuchets were pulled out, and all of them were concentrated on the castle tower for fierce bombardment, and the ferocious stones could no longer hear the waves of stone throwing at this moment, and they were mixed together like rolling thunder.

The Suzaku city wall opened widely, the female wall of the city head cracked one by one, and the broken stone bricks and tiles that burst out were excited, and they actually flew up to a height of dozens of zhang, the dust and smoke were everywhere, and the flesh and blood flew sideways where the huge stones were smashed, and from a distance, it was like a volcanic eruption, and the defenders screamed loudly and groaned, and fell down one by one. Even with Wang Yun's prior order, most of the county soldiers defending the city were caught off guard in the face of sudden and fierce blows, and they suffered heavy casualties when they landed.

After all, the battlements have been smashed, and what good can they please if they hide behind the battlements? At this time, Wang Yun and the ministers on the city tower had already fled from the city wall to hide under the protection of the county soldiers. Seeing this, the county soldiers defending the city were even more demoralized and in a mess.

"Ma Chao is too vicious!" After going down to the city, Huang Wan roared angrily: "No, we must send troops to fight and destroy those trebuchets." Otherwise, the Suzaku Gate will not take five days to let Ma Chao raze to the ground! ”

"Let these improvised infantry attack the Ma family's heavily armored iron cavalry?!" Wang Yun's face turned red at this time, and under the anger, he almost couldn't even breathe: "It's a shame that you can say such unwise words!" ”

Huang Wan was stunned for a moment, and then immediately understood the crane wing array posed by the more than 3,600 heavily armored iron horses: it was Ma Chao who deliberately spread the net and waited for him to die!

Everyone also thought of this at this time, and they were all shocked, they were usually talkative, but in the face of such a situation, they had no way to solve it. And because of this, these people couldn't help but set their eyes on Xun You.

"Don't worry, Ma Chao is just a demonstration this time. If you really want to capture Chang'an, you can attack the city a few days ago, why delay it until now? "Although Xun You was embarrassed, he still emphasized the meaning of the 'Ma family demonstration'.

"Gongda, Ma Chao's son, what do you want?!" Wang Yun was already a little angry at this time, so he grabbed Xun You's collar and asked quickly.

Xun You was about to answer, but suddenly glanced at a rocket in the sky, and immediately leaned over to knock Wang Yun down, shouting loudly: "Zhugong quickly dodge!" Ma Chao has already launched a bed crossbow rocket! ”

With a 'ding' sound, the rocket grazed Wang Yun's clothes and nailed it to the ground, and the burning oil immediately burned through Wang Yun's official uniform. Xun You immediately made a decision, ripped off Wang Yun's official uniform, and hid behind a thick wall nearby.

"Lord Situ, is it because you want to kill Cai Suiguan that you have angered Your Majesty and Ma Chao?" It was not Xun You who said this, but the seed series that hid behind the wall with Xun You.

Wang Yun was too frightened, but his brain was not slow: he immediately thought that Cai Yong was Liu Xie's confidant and Ma Chao's father-in-law...... But the Ma family dispatched all the elites and brought 300,000 Qiang people to demonstrate here, is it too much of a fuss? What's more, Cai Yong is also responsible for continuing to write the "Book of Han", his own heroic name, he would rather die than let the old man confuse right and wrong!

However, if you take personal honor and disgrace to gamble on the fall of Chang'an, is the price a little ....... No! Even if he died in this Chang'an City, future generations will still praise his loyalty, but if the Ma family saves Cai Yong, wouldn't his painstaking management be left for 10,000 years? !

No! Absolutely not!

When the old man returns to the city today, he will kill the old horseman!

Thinking about this, Wang Yun suddenly saw the entire Vermilion Bird Gate inside and outside, and instantly ushered in a rain of tens of thousands of arrows. The flaming rocket was as fast as a meteor, and almost the entire clear sky was about to be dyed red!

Yes, at this time, the infantry under Zhou Cang and Liao Hua were already guarding the bed crossbow shooters, neatly lined up in several horizontal formations, and they drove under the moat without cover, facing the mountains of corpses and blood in front and back, these archers were expressionless, and they stepped on the corpses without care, numb like zombies.

The defenders fought back desperately, shooting arrows all over the sky, but then they sadly discovered that the usually majestic mountain-destroying crossbow could not penetrate the huge shield raised by the Ma family's infantry. After a few sharp whistles, the heralds rode back and forth, the drums stopped suddenly, the captain and the captain shouted orders, and the army of bed crossbows was once again filled with crossbow arrows as they usually practiced, and shot at the head of the city under the orders of those officers.

"Bang ......." A series of dull roars, and the trebuchet crushed the soldiers on the city wall who dared to fight back into a blur of flesh and blood, and the debris shot all over the sky, instantly suppressing the firepower of the city head. There was silence for a few breaths, and then the rockets dispersed, passing through the flattened battlements and falling into the city behind the Suzaku Gate.

Under the unprecedentedly powerful firepower of the Ma family's army, the defenders of the Vermilion Bird Gate were almost killed and wounded in a few rounds, and the corpses on the city fell like rain, and the viscous blood sprayed and splashed, and it actually accumulated a thick layer on the ground, flowing down along the city wall like splashing ink, and it was as terrible and tragic as the Shura Hell.

If Ma Chao ordered the siege of the city at this time, then he would only need a rushing car to crash through the Suzaku Gate without any scruples. Then the heavy armored iron cavalry assaulted, and the entire Chang'an would instantly fall under the iron cavalry of the Ma family's army.

"Lord Situ, it's not good!" A junior colonel ran to Wang Yun's side in blood, and said in horror: "The offensive of the Ma family army is irresistible, and the soldiers defending the city and county have suffered heavy casualties. I'm afraid that in just a few moments, they will rush into this Chang'an City! ”

"Xun You, you did a good thing!" Huang Wan cursed loudly, as if the loss of Chang'an after his youth was all Xun You's responsibility.

As soon as his words fell, almost everyone stabbed their angry eyes on Xun You. Because they remembered that it was indeed Xun You who said that the Ma Jiajun was just a demonstration, and would not attack Chang'an City. And now that the situation is so critical, Xun You naturally can't escape the involvement!

"Enough!" Wang Yun shouted and scolded, but then his voice was drowned out by the cheers of tens of thousands of people outside the city, and when he suddenly looked up, he saw that the city of Chang'an was already full of fires, and the smoke covered the sky and the sun, and the sound of trebuchets projecting, bed crossbow firing, crying, screaming, groaning, and the sound of masonry collapse sounded together, and on the battlefield for several miles, the ears were buzzing, and I couldn't hear any sound clearly.

However, the next shout of tens of thousands of people in unison penetrated these deafening noises and clearly reached Wang Yun's ears:

"General Han Fuguo, Yongzhou Mu, Yongding Hou Ma Chao, want to enter the palace and ask to see Your Majesty!"

The sound shook dozens of miles away, and it was really like an earth-shattering collapse. After Wang Yun heard this, he first glanced at Xun Yu strangely, then his face almost turned purple, and finally clenched his thin fingers into fists, gritted his teeth and ordered: "Stop the war, open the city gate, and welcome the general of the auxiliary country into the palace!" ”
