Wang Shubo looked at Fan Kui's departing back, shook his head puzzled, and said, "How could he know so clearly?" In front of him and Qu Wan, there was a map of the fortifications of Wuguan, on which black lines of different thicknesses were drawn with charcoal, each line representing a different fortification and defense scale.

Qu Wan sneered, "This can only show one problem, Fan Kui is not unyielding as he said at all, and he was finally captured due to exhaustion." He was only afraid that he had surrendered to the Han army. Therefore, in Wuguan, he has full freedom and is likely to see this. ”

"But even so, it is impossible for the Han army to let him know the defense line in such detail, Yang Dasha is not really stupid." Wang Shubo shook his head and said.

Qu Wan picked up the letter that Yang Dasha gave him on the table that had not yet been torn, "Who thinks that Yang Dasha is really stupid, then wait to die, this is the war letter he is giving me, believe it or not, in this letter, Yang Dasha will tell that what Fan Kui said is true, he just wants to tell me so clearly, even if you know?" Can you beat it? ”

"Psychological warfare? That's too pediatric, isn't it? Aren't we just starting out, and a few words from him can influence us? Wang Shubo sneered.

Qu Wan glanced at Wang Shubo, tore open the envelope, and put it in front of Wang Shubo.

"How are you going to fight? Don't go out of your way or just fight according to what Fan Kui said? ”

Wang Shubo picked up the letter written by Yang Dasha, the words are very ugly, and each word is written very much, but the meaning inside is really as Qu Wan said, I did it like this, there is a kind of you to fight.

"Wuguan is such a battlefield, if you want to change the tricks, you can't change it, if you want to win Wuguan, you have to take Shaoxi Mountain first, he knows, we also know, in addition to hard attack. There's no other way to do it. However, even if it is a hard attack, there will be many ways to play. Wang Shubo stood up, "General, I won't let you down." ”

On Shaoxi Mountain, Yang Dasha is holding a telescope and is observing the Chu army on the opposite side, and now guarding Shaoxi Mountain is the third division under the command of Mei Hua, the third division took the lead in attacking Wuguan, and successfully took Wuguan within the specified time, but it also had its own losses, although the loss of soldiers was not large. But the continuous rush, the battle, and the construction of the fortifications after the war, but they are extremely tired in physical and mental strength, Shaoxi Mountain is easy to defend and difficult to attack, and now Wuguan will inevitably face the desperate counterattack of the Chu army, Shaoxi Mountain seems to be the enemy's place to take it, but because of the terrain, it is the easiest point.

"The Chu army is digging a trench!" Yang Dasha put down the binoculars. Turning his head to look at Mei Hua beside him, "There are also masters in the Chu army." I thought they would pounce like crazy people, but I didn't think they were quite calm. Wu Ya was in trouble all of a sudden. ”

"Digging a ditch?" Mei Hua raised the binoculars and looked at them carefully for a while. nodded, "It seems that the other party can't solve our ferocious firepower, and is ready to use the method of digging a trench to approach little by little, although it is a stupid thing." But it's a good idea, slow is a little slow, but it makes us very tricky! ”

"He's a good opponent." Yang smiled silly. "That's all."

It is no wonder that Yang Dasha is so confident that one invention after another of the Han State in terms of weapons has profoundly changed the mode of war on this continent, like resisting the impact of cavalry in a dense formation, it will become a tragedy in front of the Han army, and the Chu army has just demonstrated this truth with a heavy lesson. And this is only the temporary intention of the two cavalry, if it is a regular battle, the Han army bombards first with artillery, the denser the formation, the greater the casualties.

Just like the current Wuguan, the name has not changed, but the entire defense system has completely changed, the entire line of defense that pokes out, with dense fortresses as points, constitutes a circular defensive circle, criss-crossing trenches have been extended to the bottom of Wuguan, on the Wuguan city wall and on Shaoxi Mountain, there are as many as 100 artillery pieces, according to different ranges, covering the entire attack surface. In order to be able to block the 200,000 elites in Wuguan, Gao Yuan also made a bloody investment.

But obviously, the generals of the Chu army are not idiots, when they know the huge lethality of artillery, but also figure out the limitations of artillery, Wang Shubo in a very short period of time, he came up with a way, on the long-range weapons Chu army can not compete with the Han army, then can only avoid the enemy's strength, he advanced forward in the way of trench digging, so that the residual power of the artillery is not large, even if it is covered shooting, the effect will not be too good, with the minimum cost to approach the position of the Han army, when close to a certain extent, The enemy's artillery will no longer work, and at that time, the process of the battlefield will still return to the familiar scene of the Chu army, that is, the life-and-death struggle of cold weapons, life for life, and with the current strength of the Chu army, they undoubtedly have an advantage.

Yang Dasha said that Wu Ya was in trouble, and this was his intention.

Faced with such an offensive scene, Wu Ya was very annoyed, and the trench was advancing, letting him know that he was counting on the support of a lot of artillery, and what he had to face would be a face-to-face fight with the Chu army.

Fighting a tough battle, Wu Ya is not afraid, but compared to the huge numerical advantage of the Chu army, the number of Han troops guarding Wuguan is really less, the Han army has two goals, one is consumption, prolonging time, when the overall situation of Chu has been decided, the role of this army will disappear, and the second is a large number of killings, which makes the Chu army look away from Wuguan.

Now it seems that it is a little difficult to kill a large number of Chu troops before their own positions, so they must adopt the first strategy, consumption.

Wu Ya sent an engineer battalion, about 300 meters away from his position, also dug a trench horizontally, compared to the excavation progress of the Chu army, Wu Ya's engineer battalion is much more efficient, each of them is equipped with an engineer shovel and many other applicable tools, only half a day's work, before the position, a trench more than two meters deep is lying in front of the position. The trench dug by the Chu army, no matter which route it takes, will inevitably be dug into this trench in the end. The ditch of the Chu army is shallow, and the trench dug by the Han army is deep, and the Chu army wants to continue to advance, which is a hurdle that cannot be bypassed.

The Chu army also knew that the Han soldiers were digging a ditch, but they didn't know that this trench was much deeper than theirs, and when the night was about to fall, the trench of the Chu soldiers finally dug before this trench, after a short silence, the sound of war drums suddenly sounded, and countless Chu troops rushed out of the trench, jumped out of the trench they dug, and launched an attack on Wu Ya's defense line.

After running dozens of steps, a trench appeared in front of them, the trench was several meters wide, and the opposite side was higher, forming a reverse steep slope, the Chu soldiers who could not hold their feet could only jump forward desperately, the front soldiers fell on the slope, and climbed up with their hands and feet, while the ones behind were not so lucky, more people fell directly into the trench, and the depth of the trench was obviously beyond their expectations. A trench more than two meters deep is easy to fall into, but it is even more difficult to get up.

In the blink of an eye, the trench was filled with Chu soldiers, and behind them, more soldiers could not cross the ditch, but could only stagnate, and above this distance, stagnation meant death.

On the defense line of the Han army, the divine crossbow rang out, with the sound of the wind and the horn of death, and shot at these Chu troops at a rapid pace. One shield after another was raised, and the wooden shield wrapped in iron was difficult to resist the rapid fire of the Shenji crossbow, and in the sound of the shield constantly shattering, rows of Chu soldiers fell down screaming, and their bodies were intercepted into the trench.

In the chaos, after the trench that the Chu army was trying to climb up, a team of Han soldiers suddenly jumped out of the shallow ditch that was lying down, and before the sappers dug the deep ditch in front, they dug a small ditch in the rear, and with a little camouflage, hundreds of Han soldiers hid inside, at this moment, they rushed out, but what they held in their hands was a grenade, and the grenade fuse was ignited and thrown into the deep ditch.

The rumbling explosions rang out incessantly, and the screams in the ditch continued. A small number of soldiers who climbed up the ditch were also cut back by the Han soldiers with a burst of knives.

The first attack of the Chu army has not yet been officially launched, it has been declared over, and almost no one of the Chu soldiers who fell in the ditch can survive, and hundreds of casualties really make the ditch bleed and flutter. And the miserable howls of the soldiers who had not yet died made the Chu army who had retreated to the starting point even more colorless.

They can't be saved, because as long as they show their heads, they will be shot by the dense crossbow arrows on the Han defense line, and the two sides are once again deadlocked in the screams of the soldiers in the ditch, listening to the screams one after another, from strong to weak, and gradually finally inaudible.

Wang Shubo used hundreds of lives to understand the mystery of this ditch.

After nightfall, the second wave of attacks began, this time, the Chu army appeared in front of the trench with a sand hug, after throwing the soil bag in his hand into the trench, the Chu army immediately lay down to avoid the dense rain of arrows from the opposite side, even if they had been prepared, there were still people who were hit by arrows and fell, and many Chu troops fell into the ditch after being hit by the arrow, and it also became the material for filling the trench.

Half an hour later, the trench in front of the Wuya position was filled in at the same level as the trench of the Chu army, and a large number of Chu troops finally advanced here along the trench they had dug. The new Chu army was replenished, and the trench was once again slowly excavated forward, and by midnight the trench had advanced to about a hundred paces from the Han line. It was no longer possible to dig any more, and above this distance, there were already Han soldiers with strong arms who were able to throw grenades over and inflict casualties on the Chu army. Next, there will be a charge of blood and fire, but fortunately, the charge will be launched above this distance, and the artillery of the Han army will not dare to fire. All the Chu army had to face was the officers and soldiers of the Fourth Division of the Han Army in front of them. (To be continued.) )
