This kind of thankless work, Lu Zhao is naturally too lazy to do it, don't look at the Bingzhou army There are only a thousand people stationed there, but for Lu Zhao, it is a trap, and the Bingzhou army is waiting for him to take the bait.

Of course, Lu Zhao will not be fooled, he strictly ordered his subordinates, no one is allowed to open the city to fight, let alone attack the enemy camp, strengthen the defense and vigilance in the city, and do not give the state army any opportunity to take advantage of.

The outer city wall is lost, even if there is a great unwillingness, it is also suffering, now is not the time for them to counterattack, now the first task of the Jizhou army is to hold the inner city of Xindu, and must not let the Bingzhou army cross the thunder pool half a step.

This is Lu Zhao's bottom line, Xindu City must be defended, and it must not be lost in his hands.

In order to prevent a possible surprise attack by the Jizhou army, everyone stayed up all night with their eyes open, staring at the direction of the inner city, and did not dare to relax for a moment.

He didn't expect thousands of people to be able to block the attack of tens of thousands of enemy troops, these more than 1,000 people just played a warning role, if the Jizhou army really dared to attack, a thousand people only needed to drag them for a moment, and Yanghu would personally lead the army to come and inflict heavy losses on the enemy.

However, until dawn, there was no incident on the forward position, and the Jizhou army always firmly closed the city gate and had no intention of going to war.

After a night's rest, the soldiers of the infantry battalion were all energetic and high-spirited.

Yesterday, the attack of the infantry battalion was vigorous, and all the soldiers had the idea of eating the city of Xindu in one go, but the time was short, and they did not have the opportunity to set foot on the head of the inner city.

Obviously, this made the soldiers of the infantry battalion quite unwilling, and today the soldiers came to the city again, and their desire to fight was extremely strong, and the captains asked Yanghu to fight, all wanting to be the vanguard of this siege.

However, Yang Hu did not move for the time being, and the first thing he had to do was to do a good job of covering before the siege, so as to minimize the casualty rate of the soldiers during the siege.

In fact, yesterday's suppression of the city by the crossbowmen of the state army was very powerful, and today Yanghu will of course continue to implement this tactic, and it will be further strengthened.

The catapult can't be transported in for the time being, but the catapult can, compared to the huge bulky size of the catapult, the catapult is much lighter, and this one can be easily lifted by four soldiers.

Yanghu chose the place where these crossbow carts were placed on the outer city wall that had not yet collapsed, and the collapse of the outer city wall was not like a cliff, but a huge slope through which the state army could climb the outer city wall.

After a simple rush repair, the state army quickly built a road for the crossbow carts to ascend the city, and a car was carried by four people, and Yanghu only needed to send a force of 200 people to assist the crossbow soldiers to carry the crossbow carts to the city wall.

Due to the distance between the inner and outer city walls, this also made it impossible for the Bingzhou army to deploy archers on the outer city walls, but it is estimated that Lu Zhao did not expect that the Bingzhou army still had weapons in their hands that had a longer range than bows and arrows, in addition to catapults, it was a crossbow cart.

The range of the ballista is between that of a normal bow and a catapult, so placing them on the outer city wall is just enough to shoot the crossbow arrow across the opposite inner wall.

Since the outer city wall and the inner city wall are on the same level, the ballista does not need to shoot from the back, only the normal flat fire, which can reduce more dead angles than the upward fire, achieve full coverage of the city head, and better suppress the defenders on the city head.

What's more, the archers of the Jizhou army could not shoot bows and arrows into the outer city wall, which means that they could not destroy the repeater carts, so that the repeater carriages could attack the inner city wall with impunity.

The Ballista is an improved version of the Repeater Caribbean, and the design principles of the two are the same, but the Repeater is portable and suitable for use in any terrain and position, while the Repeater is more powerful and has a longer range.

Ma Jun is indeed a genius who has not been seen in a hundred years in mechanical manufacturing inventions, and many of his inventions are beyond the existence of this era, but due to the arrogance and prejudice of most people in this era, these inventions of Ma Jun are pearls and dust.

I have to say that this is the sadness of the times, those in power are only obsessed with power tricks, resting on their laurels, but turning a blind eye to the products of the war that can change this era, and only regard Ma Jun's inventions as strange tricks.

The reason why Emperor Wei Ming admired Ma Jun was that Ma Jun designed a toy like a hundred operas for him, but Ma Jun's true value was never discovered, and all his inventions and creations that could change the direction of the war could only be thrown into the pile of old papers, sealed and moldy.

Ma Jun's life was depressed, although he was an official and did his best, but his life's ambitions were not realized, until he met Cao Liang, his life really glowed.

Bosom friends are hard to find, Bole is nowhere to be found, Ma Jun has been stumbling all his life, until the twilight of his life, he was fortunate to meet Cao Xian, all his inventions and creations, with the help of Cao Liang, one by one into real objects, and then it was promoted and equipped into the army, which greatly improved the combat effectiveness of the state army.

Ma Jun died without regrets, and was able to witness the things on these drawings become real combat effectiveness, and the value of his life was realized, and he could finally smile and star.

The reason why Cao Liang can lead this army from small to large, from weak to strong, in addition to his courage, wisdom and strategy, the biggest reliance is on these inventions and creations provided by Ma Jun for him, and with these weapons that transcend the times, Cao Liang is even more comfortable and at ease.

The crossbow cart was carried to the city wall, and the arrangement was quickly completed, and at the same time, thousands of archers also entered the designated position, and Yang Hu gave an order, and the archers and the crossbow cart released arrows at the same time, and the dense arrow rain attacked the head of the inner city of Xindu, completely shrouding the head of Xindu in a rain of arrows.

Lu Zhao has been closely following the movements of the Bingzhou army, when the Bingzhou army moved the crossbow carts on the city wall, Lu Zhao secretly shouted badly, don't look at the crossbow cars of the Bingzhou army There are only about 100 of them, but it is extremely fast in rapid fire, extremely penetrating, and the blow to the defenders is particularly powerful.

If the Bingzhou army only used archers to attack on the back, Lu Zhao was not too worried, after all, the Jizhou army also had archers, and they could counterattack, but the crossbow carts were out of their range, and they could only be beaten passively.
