It is difficult to stop the enemy's offensive with the trenches alone, after all, the Wu army is numerous, and a bag of soil on each person's back is enough to pave a road in an instant.

In fact, as the defense system of the city, the trench was just within the range of the bow soldiers in the city, and there were traps around the trench to resist horses and antlers, and once the Wu army approached the trench, these obstacles must first be cleared.

After entering the range of bows and arrows in the city, the Wei army in the city will naturally be unceremonious, and will attack the enemy with a fierce rain of arrows to delay the enemy's attack.

As soon as Wang Ji saw that the Wu army had advanced to the front of the trench, he waved his hand resolutely and calmly, and ordered: "Release the arrow!" ”

The Wei army immediately shot with a bow, and the arrows were like flying locusts, and they shot directly towards the city.

This distance is just right, it is completely calculated, and the bow with the same strength can be shot at the edge of the trench, and if the enemy army reaches the edge of the trench and wants to counterattack with a bow and arrow, because it is a back-fire, no one else can shoot the arrow into the city except for people with special arm strength.

Therefore, the Wei army did not need to worry about the counterattack of the Wu army at all, and the archers of the Wei army could shoot arrows downward with impunity, shooting Wu soldiers continuously.

This first wave of archery brought a lot of casualties to the Wu army, most of the Wu army was wearing leather armor, this kind of leather armor was almost defenseless except for being light, and the arrows of the Wei army could easily penetrate their leather armor.

Only Wu Bing, who held a shield in his hand, could barely block the arrows and escaped.

But among the Wu army, the proportion of shield soldiers is not too high, so this wave of arrow rain killed and injured a lot of Wu soldiers.

Seeing that the situation was not good, Lü Ju, the partial general who was in charge of the siege command, ordered the Wu army to retreat slightly and withdraw beyond the range of the Wei army's bow.

This moat was undoubtedly repaired by the Wei soldiers in the past two days during their siege, and the entire moat was not only widened but also deepened, which still had a great impact on the leap of the Wu army.

Of course, Lu Zhi was unwilling, at this moment they mobilized almost all of the 50,000 troops and put them into the attack, this force input, and the attack of more than 20,000 people a few days ago, more than doubled, Zhuge Ke for this attack, almost poured all his blood.

Lu Ju, who took the initiative to ask Ying to serve as the siege commander, knew very well that if he couldn't get a satisfactory result today, he was afraid that he would have to suffer a heavier punishment than Tang Shiliuzan.

Therefore, he must make something to achieve in this battle.

A small trench could not stop the advance of the Wu army.

Lu Yi immediately adjusted the deployment and sent a large number of shield soldiers to the front, with a dense shield on his head, which could completely resist the arrows of the Wei army.

With a shield on his head, the movement under his hands did not stop, and bags of sand passed from underneath and threw themselves into the trench.

It is not an easy task to fill in this trench that is several miles long and ten zhang wide, even if the Wu army is numerous, but it is still very difficult to break through to the city in a short time.

Therefore, Lu Ju was not prepared to fill all the trenches in one go, but selectively filled them in sections, each of which only needed to be filled dozens of zhang wide, so that the Wu army could pass smoothly.

Lü's plan worked quite well, and the Wu army was progressing very well, relying on the shields on their heads for protection, which could minimize the casualties of the Wu army, and these shields formed a shield wall, so that the Wei army's bows and arrows almost lost their advantage.

Wang Ji looked at the shield wall of the Wu army, and simply ordered the archers to stop shooting, so that shooting over could not effectively kill and injure the enemy, it was a waste of arrows, and the gains outweighed the losses.

The archers stopped shooting, which did not mean that Wang Ji was helpless, and seeing the Wu army attacking the city, he ordered the catapult to come over and use the stone throwing to attack the shield array of the Wu army.

Anfeng City is not equipped with too many catapults, only a few dozen, and due to the limited space on the city wall, it can only accommodate the smallest type of catapult, which only needs five or six people to pull and complete the projection.

However, this kind of catapult performance is still very sharp, it can project stones weighing up to twenty catties, twenty catties of stones look inconspicuous, but thrown high and then smashed down, those wooden shields are really unbearable, immediately split, even the Wu soldiers below are also a whimper.

The accuracy rate of the catapult hit is actually very poor, but there are too many Wu soldiers under the city, dense, and the stones are projected out, although it is not guaranteed to be a 100% hit, but the probability of falling on the top of Wu Bing's head is extremely large, basically one stone is thrown out, most of them can hit one or more Wu soldiers.

When the bow and arrow are silent, the catapult attack can still receive miraculous results.

Cao Liang saw it, and couldn't help but sigh secretly, just as the Wei army could upgrade all the existing catapults according to Ma Jun's proposal, then the combat effectiveness of the Wei army could be significantly improved, whether it was the serial catapult developed by Ma Jun before, or the counterweight catapult jointly developed with Cao Liang, they could all show their might on the battlefield.

It's a pity that the people in power in Wei are not enthusiastic about this, so the catapults that have the opportunity to improve are still at the level of the battle of Guandu forty years ago.

Although dozens of catapults can achieve results with every projection, in the face of tens of thousands of Wu troops, this number of catapults is like a drop in the bucket, and cannot really influence the progress of the battle.

The trenches were quickly filled in by the Wu army, and the Wu army swarmed up along the passage and rushed straight to the foot of Anfeng City.

Catapults are not as flexible as bows and arrows, and can attack distant targets as well as near targets, while catapults can only attack targets farther away, and it is somewhat powerless against the Wu army that has already attacked the city.

Wang Ji ordered the catapult to be withdrawn, and all the soldiers defending the city were arranged in place and ready for battle.

Everyone knows that the next battle is the real city defense attack battle, and the long-range battle just now is just a warm-up.

When Wu soldiers approached the city, a series of ladders were quickly erected, and the height of these ladders was obviously designed, neither high nor low, and they were just set up a little below the battlements of the city wall.

If the ladder is low, it will be difficult for the besieging soldiers to climb the ladder, and after the ladder is high, it is easy to be destroyed by the defending army.

And this ladder is obviously tailored to the height of the walls of Anfeng City, the height is just right, if the soldiers of the Wu army can climb to the top, they only need to jump one step to reach the city.
