The excavation work in the night is still going on, and the king of Aro in the city of Tongwan is still hesitating.

Although the architecture of Tongwan City is strong, it has not been able to transcend its time. Helian's ambition did not have enough level of scientific and technological civilization to match it, so the structure of Tongwancheng was still a typical structure of city defense in the Cold Weapon Era, that is, the four-sided urn city structure was adopted, and the vicinity of the urn city gate protruding from the city wall became a shooting dead end, and the soldiers of the Eighth Route Army who hid in the hole of the city gate and dug without stopping could basically be protected from the damage of bows and arrows from both sides. As time passed, the ground in front of the gate was gradually excavated, and the earth piled up on both sides became higher and higher, gradually forming a small bunker, which hid the figures of the excavated soldiers, and it was now difficult for the party soldiers to see the enemy troops under the city gate even if they threw fireballs.

At present, the most powerful means of striking at these enemy forces gathered in front of the city gate is the counterattack of the infantry in the city, which requires King Aro to make up his mind to open the two gates of the city to the north and let the infantry out of the city.

Of course, there is also a better way, the south gate of the urn city is opened first, the infantry is gathered in the urn city, and then the south gate is closed, the north gate is opened, and the infantry rushes out to fight the enemy hand-to-hand.

It's just that the vast night has always troubled King Luo's judgment, and it is a taboo for soldiers to open the city gate at night, and no one can say whether the Eighth Route Army has ambushed enough siege troops near the city gate. Opening the gates of the city in the darkness of night would have to take a great risk.

Theoretically speaking, as long as the south gate of the urn city is closed, even if the north gate is broken through, the enemy army enters the urn city, it is just a death place where the enemy is attacked on all sides.

But the trouble is that the night battle, the defenders at the head of the city can only give the enemy troops under the city indiscriminate coverage and damage, once the enemy and our armies are mixed together, basically the long-range weapons at the head of the city have the same chance of killing and injuring their own people as killing and injuring the enemy.

In other words, your own infantry will not receive any support from the head of the city.

That's all, the most difficult thing for King Arrow to decide. That is, what is the strategic intention of the Eighth Route Army.

At the meeting a few days ago, although there were differences within the top echelons of the Dingyan Army on the enemy's intentions, the relatively unanimous opinion was that Li Wenge would not have the illusion of relying on a thousand partial divisions to attack and unify ten thousand cities. At most, they should make harassing attacks to induce the main forces of the Dingyan Army to go out of the city and fight in the field, and strive to achieve a decisive victory in the movement battle.

Li Wenge committed a taboo in the soldiers, and instead of taking the south road, he made a detour to the north to attack the city.

If Li Wenge's main force was really here, then this army would actually be in a desperate situation. If you can't take Tongwancheng in a short time, the main force of Tuoba Yiyin's cavalry and the defenders of Tongwancheng will attack from the north and south, and this partial division will have no physiology.

If Li Wenge's main force was not here, then this army at night was a feint, in order to make his own judgment wrong, to mobilize the main force from the south to the north, and create conditions for Li Wenge's troops to seize the southern city.

Or Li Wenge's plan is even greater, his target is not the city he guards, but the Tuoba Yi Yin troops who have disappeared in the north of Wudinghe. Li Wenge hoped that through this kind of harassment at night, he would light a beacon fire and call on Tuoba Yi Yin to return to the army. And it set up an ambush halfway to defeat the main cavalry force of Tuoba Yiyin first.

Although neither of these explanations is unreasonable, King Aro always felt that something was wrong.

The behavior of this unit in charge of the feint is really strange.

Even if the north gate of the urn city is dug up, what good can it do to conquer the Tongwan City?

As long as the south gate of the urn city is not broken, the Eighth Route Army will still not be able to enter the city. These enemy ground vanguards are doing pointless things.

Here's where things are to blame.

King Luo may believe that Li Wenge has other plans, but he will never believe that Li Wenge is an idiot and fool.

This Eighth Route Army is cunning and cunning......

Therefore, despite the fact that the presence of enemy forces outside the north gate had been confirmed, King Aro still did not give the order to assemble his forces towards the north gate.

The current enemy situation is not enough to prove that the enemy outside the north gate is really the main force of the enemy, and in the absence of confirmation of this, King Arrow will not act rashly.

With the current strength of a pivotal place in the northern city, it is enough to deal with these small enemy forces. There is no need to redeploy additional troops.

King Luo was watching, and he still hoped to be able to accurately judge Li Wenge's strategic intentions.

At this time, a flash of fire flashed in the gate hole, which was blocked by a mound of earth and the north wall of the urn castle, and then a bright light was transmitted from the doorway, and it seemed that the enemy troops who were digging inside had finally lit torches and other lighting tools.

King Arrow clenched his fists.

He still hadn't given the order, and now the situation under the city was clear, and some enemy troops were hiding in the darkness in the distance. Outside the effective kill range of the bow and arrow. At most, there were less than twenty enemy troops continuing to excavate in the doorway. It seems that there are not too many enemy troops outside the North City. With just one charge, it can be defeated.

However, it was not yet dawn.

Although there seem to be few enemies hiding in the dark, the number has not been confirmed.

King Aro feared that once he sent his infantry down the city to fight, hundreds or even thousands of enemy troops would pour out of the darkness.

Although this did not affect the overall situation, the infantry fighting in the lower city could not turn back, and in the face of the superior enemy army, it was impossible for the defenders to open the south gate of the urn city to receive these infantry into the city.

Although King Aro did not hesitate to sacrifice some soldiers in order to win when necessary, the problem was precisely that he could not tell if it was necessary or not.

The enemy is doing something that he knows is useless, even if he really digs into the urn city, what can he do?

As for digging a tunnel leading directly into the urn city, King Luo was not worried at all, and the dozen or so soldiers under the city gate might not be able to dig in even if they dug for three days and three nights......

What King Aro is hesitating about now is not whether to go down to the city to fight, but whether to light a beacon fire.

Just summoned the main force back, King Luo was a little unwilling.

You have to wait until you have drawn out all the main forces of the enemy before summoning the main forces.

And where is the main force of Li Wenge ambushed under Tongwan City? The soldier is holding a parchment drawing and directing the soldiers to excavate.

"Dig a foot inward, being careful not to dig through, and keep a foot and a half thick between it and the ground of the inner city. If you dig too much, use the excavated soil to shoot the ......"

"Dig three feet diagonally downwards to leave a trapezoidal slope ......"

"There's a little less space down there. It's an inverted trapezoid, not a regular trapezoid......"

"It's too deep to dig up here, and the medicine will spray out, who will go outside and pick up some soil?"

"The inner slope should be inclined outward, not too straight......"

"The angle between the two sides is too different, dig some more here. Pay attention to the balance of the inner and outer slopes......"

Under the city gate, a foot and a half thick wooden city gate has been dug out of a large hole large enough to accommodate three people, this hole is quite strange shape, wide at the top and narrow at the bottom, judging by the meaning of these soldiers, it seems that they are not ready to continue digging inward, but digging more and more holes

More than a dozen soldiers were digging pits with dirt and digging holes, busy under the command of Xiao Daotong, each with sweat on their faces and their clothes already wet with sweat.

After a while. The fire flickered under the gates, and the temporary lighting torches were extinguished.

It was a signal, and with the sound of footsteps, it seemed that three or five people flashed out of the darkness and headed straight for the city gates.

The pupils of King Arrow on the enemy tower contracted again, although he couldn't see it. But he could hear that the archers on the enemy tower raised their bows and arrows again.

Arrows cannot be accurately shot in the dark, and the probability of a diffuse shot is too low, so the archers are hesitant.

King Aro gritted his teeth and stared hard at the city, as if hoping to see some clues......

In the dark, the boy instructed the soldiers to wrap one after another of the tarpaulins they had carried around and stack them in the pit they had dug, and then carefully took out a rope-like roll from his bosom.

One of the soldiers touched it curiously. only to find that it was a rope like oily paper.

The boy was startled, and said with a stiff face: "Don't touch it, this is a treasure, there is only such one, if it is broken, the adults and the master will kill my head......"

The boy placed the rope, and then a dozen people worked together. The gullies dug out at the right time were filled in one after another.

As the large pit in front of the city gate was gradually filled. The boy became more and more cautious, and no longer let others do it. Instead, he began to fill in the gap between the pit and the city gate with a small spade.

After filling it for a while, he took down the package on his body, took out a large piece of dough from it, and carefully filled the gap around the rope.

A rooster crows in the distance.

A few people poked their heads out, and the night outside seemed to be less intense.

It's almost dawn.

As these soldiers and the Dao boy tiptoed back a hundred paces away from the city gate, the fine seal minda who had been guarding there finally let out a sigh of relief.

A look of disgust appeared on his face, and he said to a soldier beside him, "Go and inform your lordship that the delivery task of the second kicking team has been completed." ”

Two Kicking ...... God knows what this strange term in the mouth of this General Li means......

A mile away.

Li Wenge looked at the panting soldier in front of him, and his mood became inexplicably nervous. It wasn't until Shen Chen shouted for the third time that he came back to his senses.

Shen Chen instructed the heralds: "Blow the trumpet and inform Zhang Guizhi to lead the cavalry across the river." ”

Li Wenge sighed: "Release the water at dawn...... Some wasted ......"

Shen Chen glanced at his boss a little inexplicably: "The enemy's cavalry is no more than a hundred miles away from us, this distance is enough to rush back in one day, if the water is released late, we will be attacked by the enemy...... It is nearly 130 miles from the place where the dam was built upstream, and the river will not rise until noon at the earliest. ”

Li Wenge smiled bitterly: "If we wait until the enemy cavalry returns to cross the river before releasing the water, wouldn't it save us a lot of trouble?" ”

Shen Chen rolled his eyes: "Daydreaming!" ”

Li Wenge did not feel angry at all, and said with emotion: "It's not a pipe dream, if you can have a set of radio equipment and flow mapping equipment, you can do it!" ”

Shen Chen sighed, and the boss began to say something that he couldn't understand anyway.

"My lord, you can do this. Xia Guan has already racked his brains, if you are still not satisfied, Xia Guan has nothing to say. ”

Li Wenge shook his head self-deprecatingly: "You have done your best." I'm very satisfied......"

Speaking of this, his facial expression became solemn, and he said in a cold tone: "Order Di Huaiwei's armor to prepare." ”

With a long trumpet, Di Huaiwei, who was standing not far away, stood up, turned his head excitedly and shouted the command: "Assault - stand up——! ”

One hundred veterans of the Eighth Route Army obeyed the order and stood up in the blink of an eye. A hundred people have stood in a ten-by-ten phalanx.

"Stand up—take a break—put on your armor!"

With the sound of a rope, the elite infantry was soon wrapped in a hundred sets of bird hammer armor.

An iron array gradually took shape, and the unique sound of metal from the impact of the armor pieces accumulated into a small number, and it reached the ears of King Arrow, who was far away on the castle tower, along the morning breeze.

The face of the veteran party item changed. "Hold a gun—walk in unison—walk—

There was a regular sound in the distance, the sound of falling footsteps and the sound of armor clashing and shaking, and as the sky grew brighter, a phalanx of black-pressed ironclad infantry slowly moved towards the city gate.

King Aro finally opened his mouth and gave the order......

"The archers gathered, moved all the stone bullets and rolling logs to the city, and ordered the commander of the southern city to drag the two bed crossbows to the north!"

The pivot who followed him paused. Then he asked, "Do you want to transfer a pivotal inscription from the south?" ”

King Luo said impatiently: "The enemy situation is still unknown, the defenders of the southern city do not move, just drag the bed crossbow over, ...... quickly"

The cardinal promised and went down to arrange for the herald to convey the order.

King Arrow's eyes were fixed on the front of the enemy tower, and the army that made a neat noise was still unseen in the dim mist. But its momentum had already spread through the distance, and the night that had gradually receded and the morning mist that had not yet dissipated trembled slightly with this momentum.

This is undoubtedly a workhorse.

King Arrow has already made a basic judgment.

But he could not tell whether this was the entire main force of the enemy.

With many years of experience on the battlefield, King Luo could certainly hear that although this voice was terrifying, it was just a small group of 100 people.

A mere 100 people, even if they are well-equipped, can they allow these 100 strong soldiers to enter through the wall?

King Luo felt more and more weird, and the events of this night always made him feel frightened. Although this was not the first time that the Tuoba family had confronted Li Wenge's army, King Luo always had a feeling in his subconscious that there was something he didn't know.

His eyes were fixed on Di Huaiwei's infantry, Li Wenge had a big conspiracy, and it must be implemented through this strong army, King Luo wanted to see what kind of tricks this Eighth Route Army could play this time.

In the east, the sun slowly rises above the horizon......

Just when King Arrow's mind was attracted by Di Huaiwei's infantry, on the ground directly in front of the city gate, a strange spark was rapidly approaching the city gate......
