Gu Han looked at the enemies who were pressing into the dock fort from all directions, and his face turned a little pale. Unlike a regular castle, the Dock Fort does not occupy a large area, and at first glance, it looks like a small reef in the middle of the waves of the sea, which may be submerged by the sea at any time.

"Judge Gu, the dock fort has small benefits, Kanyan is still quite experienced in building the dock fort, and the ease of defending and attacking this dock fort is not lower than the Shijiawu we fought in Yingzhou. But this time, it was our defense, and the opponent attacked. Li Rui seemed to see through Gu Han's mind and said with a smile.

Gu Han nodded, the construction of this dock fort was indeed painstaking. The base is unusually wide, and the main body of the dock fort is built on the base, and between the base and the main body, there is also a small platform.

It's this small platform that will cause great trouble for attackers. The siege ladder must be placed more flat before it is possible to reach the dock fort, which also means that the ladder should be longer, but longer means that the distance is longer, and in this case, one more step is almost the difference between life and death.

What's more, last night, the right guards raised the city wall again in the snow, and after watering, after a night, it was already as hard as iron, which made the possibility of putting the ladder directly at the bottom of the dock fort completely gone.

Such a dock fort is essentially a military fortress, it is not as large as a city, but it is more difficult to attack.

"Kan Yan has worked hard, and I don't know how many people have died to build the dock fort, but now it has become a fortress for us to harvest them, thinking about it, he must be extremely uncomfortable now." Gu Han, who was a little more relaxed, said with a smile.

"That's natural, and it's not easy to change anyone." Li Rui laughed.

The laughter of the two men was interrupted by the sound of war drums beating from below, and their eyes fell into the distance, and from the enemy array to the west, a team of about two thousand men came out, carrying a ladder, towards the dock fort.

When they were about halfway there, war drums sounded in three other directions at the same time, and the enemy on three sides slowly pressed in at the same time.

"The one who took the lead in attacking was really that unlucky ghost from Kan Yan." Li Rui said: "In the other three directions, in addition to Liu Siyuan's headquarters in the north, the other two directions are also slave troops. ”

"Will Kanyan be the main direction of attack?" Gu Han asked.

Li Rui nodded: "This dock fort is built by Kanyan, of course he knows where it is the weakest." Naturally, he took the lead, and in the other three directions, except for Liu Siyuan's headquarters, which was a feint, the others would also be fought hard. ”

"Three main attacks?" Gu Han was a little puzzled.

"There are a lot of them!" Li Rui explained: "Moreover, Liu Siyuan did not treat these slave soldiers as human beings, if they die, they will die, and they can arrest more people." ”

Gu Han nodded first, then shook his head.

"Judge Gu, let's go to the back and watch the battle!" Li Rui said: "If you fight, I won't have the energy to take care of you." ”

"I don't need you to take care of me." Gu Han said angrily: "My knife can also kill, and I have also killed bandits." ”

Li Rui patted Gu Han on the shoulder: "Judge Gu, you are sent by Gongzi to negotiate with Zhang Zhongwu, and I can also see that Gongzi values you very much, the gentleman does not stand under the dangerous wall, and the army fights, unlike your previous single-handedness, a small accident is enough for you to have some accidents." I don't want to see that. ”

Seeing that Gu Han was still going to refute, Li Rui continued: "Now I still have the strength to spare, I don't need you to go into battle, when there is really a shortage of manpower, I will use you, and I will never be polite, now, you better go and rest!" ”

Gu Han thought for a moment, nodded, and turned around and walked inside.

When he walked inside, he heard Li Rui shouting loudly: "In this round of attack, you are not allowed to use strong crossbows or arrows, you can only use stones, wood, knives and spears in your hands." ”

At first, he was a little puzzled, but then Gu Han figured it out.

The first to go into attack was the slave army, these people's protection was very weak, and the overall combat ability was not strong, Li Rui didn't want to use weapons like crossbow arrows on them. These sharp long-range weapons, of course, must be kept for Liu Siyuan's headquarters. You must know that although Li Ze's troops have always been more and more on crossbow arrows and other weapons, but this time I don't know how long it will take, Li Rui chooses to be cautious and prepared, which is the experienced performance of a veteran general who has experienced a hundred battles.

The slave soldiers cautiously carried all kinds of things that could resist the arrows and advanced forward, especially the Kanyan Division, but they had received the power of the crossbow arrows of the right guard in the field, and attacked again at this moment, even if they did not have the shield of the clan, but even if they were holding a wooden plank, it would give them great psychological comfort.

It was quiet above the dock fort, they walked through the range of the crossbow, they walked through the range of the crossbow machine, but they did not usher in any blow, until they came to the range where they could attack, and the dock fort was still quiet.

Apart from the fluttering flags, they couldn't even see a single soldier on the right side.

"Attack!"

Walking to this place, that is, stretching out the head is a knife, shrinking the head is also a knife, Kan Yan raised the knife and shouted, and more than 2,000 subordinates also shouted, rushing forward. From time to time, there were scattered feathered arrows at the head of the city, but there was still no counterattack from the dock fort.

With the sound of clanging, a number of specially lengthened ladders set up the city, these ladders were made overnight according to the previous height of the fort, and now the fort has grown taller overnight, so that the ladders are about a meter away from the top of the fort. To climb to this place, you need to climb it with your bare hands. This, of course, gives the defender greater convenience.

It was strange on the battlefield, in three directions, the slave army set up hundreds of ladders and launched an attack at the same time, but not a single arrow was shot down in the city.

"Father, what does Li Rui want to do?" In the distance, in the headquarters of the Liu clan who were watching the battle, Liu Siyuan's second son Liu Dai asked a little strangely. "Why didn't he use long-range attacks? If it is used, I am afraid that our troops who can reach the bottom of the dock fort will lose at least half of it. ”

"Li Rui looks down on these people." Liu Siyuan took a deep breath: "He doesn't want to waste crossbow arrows, but he must have another means of coping." ”

Before Liu Siyuan's words fell, a huge voice came from the city wall.

On top of the city wall, huge beams appeared out of thin air and smashed into the ladder leaning on the city wall.

"Slap the stick!" Liu Dai lost his voice.

It is indeed a modified lever.

Right Xiaowei tied several extremely elastic bamboos together, and then tied a trunk the thickness of a sea bowl horizontally at the top, and what is even more alarming is that there are iron bars on top of the branches to penetrate it, and the exposed part is cut out of an oblique angle. With a loud noise, the bars bounced up from behind the walls and smashed down into the ladders.

There was almost no accident, and the ladder broke immediately under such a heavy blow, and the slaves who were climbing up the ladder immediately screamed and fell down one by one.

After a round of blows, the sticks were quickly pulled back by the right guard, and once again disappeared behind the city walls. The only one who was able to climb up the ladder to the top and try to jump up was the one that attacked from the northwest corner, and in this direction, there were several ladders that could avoid the blows of these poles because of the corners.

But they won't end up any better than the attackers elsewhere.

This distance of more than a meter has become their life-seeking Yama.

Spears with handles were waiting for them in this direction, but as soon as anyone came up, dozens or hundreds of long men immediately stabbed at them.

The offense looked violent.

The defense was light-hearted.

But the result was a bit tragic, and during an attack, the corpses of the slave soldiers were covered under the dock fort.

"Gather crossbows, archers, and give support." Liu Siyuan stared at Wubao and said.

At Liu Siyuan's headquarters, one after another strong crossbows were pushed out, and rows of archers also came out of the crowd and pressed towards the dock fort.

Amid the thunderous drums, the whistling of crossbows resounded across the battlefield.

Liu Siyuan's strong crossbow is very poorly made, in fact, it is a spear one by one, except for a spearhead and a wooden pole, such a strong crossbow, the trajectory of the flight is extremely unstable, of course, it is not accurate, but the victory lies in the large number, and hundreds of them are shot at one time.

Li Rui finally got a little serious.

Because the wall that is built up with snow and then frozen, as long as it is hit, it will collapse for a short time, and some strong crossbows are shot into the air, turning around and diving down, which will pose a great threat to their own soldiers behind the wall, so that if you take a hit, half a life will be lost.

The black-pressed feathered arrows fell from the sky, the right Xiaowei soldiers raised their shields, and the clanging sound was endless, and under the cover of the rain of arrows, the morale of the slave army was greatly shaken, and they launched an attack again.

This time, in quite a few places, their ladder finally reached the city wall.

The lever was raised again, and fell down again.

This time, however, casualties began to appear in the city.

The soldiers operating the sticks, even though the soldiers raised their shields to cover them, in the roaring rain of arrows, there were still people injured and some killed.

Once, twice, three times.

Kan Yan was about to cry, and none of his men succeeded in climbing the city wall in three successive attacks, but instead left the corpses under the city layer after layer.

It wasn't until the sound of the trumpet of the retreating soldiers finally sounded behind him that he breathed a long sigh of relief and took the lead in retreating as if he had been pardoned.

"Father, it still works. Why the troops? Liu Dai asked.

"Our trebuchet has not yet been built, and crossbow arrows alone will not pose much threat to the city, such an attack will only give Li Rui a chance to kill and injure a large number of slave troops, these people, it is still useful to keep them." Liu Siyuan said. "Tomorrow, tomorrow, at least a dozen trebuchets can be built. Today's attack is just an appetizer, and I understand what Li Rui means, he will never break through, he will be here to wait for help. ”

"Where are the reinforcements? Liu Chenglin was pinned down by General Deng. The other troops closest to here are the troops of Cangzhou, can they rush over? Liu Dai said with a smile.
