Not long after the siege of the day stopped, the Yan Clan's fortress, which was the second fortress that previously belonged to Li Dian, had become the rear camp of Gao Shun's army. Now that the night has come, the military tents everywhere in the village are filled with blood, and the Yan army was beyond Gao Shun's expectations during the day, and successfully attacked the city for a while, but due to lack of preparation, it was beaten down when it was able to occupy the head of the city, so that Gao Shun did not even have the opportunity to send troops to reinforce.

waited for Mingjin to withdraw his troops, but Jiao Gao Shun sighed for a while...... The enemy's garrison in the fortress is already very empty, and if you are fully prepared for a strong attack during the day, eighty percent of them can rely on forcible capture to take the fortress.

In the past few days of fighting, although Gao Shun captured two cities, the casualties on both sides were not large, but in general, the Yan army suffered slightly more casualties, and it was already 3,000; The casualties of Cao's defenders at Chengfu were much smaller, with a thousand killed at most. But for Gao Shun, the benefits of uprooting a city are greater than killing and wounding thousands of enemy soldiers.

Zhang Liao's orders dictated that Gao Shun needed to stay here for a month or two to attract Cao's army in order to achieve the effect of striking the east and attacking the west. This limited Gao Shun's tactics at the beginning, and all the tactics of rapid breakthrough could not be used, leaving him with few options except for attacking and seesawing.

Gao Shun needs these cities very much, even the city of Chengfu, he needs one city after another to support him for the battles that will take place here in the future.

Although the Yan army almost lost a complete lieutenant department in the battle for a few days, the morale of the sergeants was not low, but they were eager to try because they found out the bottom of the Cao army. The soldiers didn't know the mission that Zhang Liao gave to Gao Shun, they only knew that the defenders of Chengfu City were not difficult to fight, and during the day, only two captains almost captured the city when they charged at the same time, and if they waited until tomorrow, this city would definitely be theirs.

This emotion is contagious to everyone, and in the course of the war, people invariably choose to temporarily forget the robes that died on the siege road, and think about how to fight bravely in the next battle. Even the soldiers in the wounded barracks who had participated in the battle spoke with ease...... What else can grieve them? They are wounded and unable to fight again, and the general will not send them to the front again no matter what. And looking at the enemy's posture today, it is obviously not enough to hold on for another day, this city that is supported in the middle of Chengfu City will be theirs in a blink of an eye!

It is no wonder that the morale of the soldiers is high, and most of the earthworks approaching a hundred paces in front of the camp have been built. In fact, it doesn't matter if most of it is still half, the city is not a city, the wall is just a foot high, and the soil that is one person high can be used as a shooting platform at will, and even if you are not worried about the mud, it will be lower, and you don't need to build a three-zhang high earthwork like the siege to ensure that the enemy arrow rain is suppressed. Once this kind of fortress is suppressed by the rain of arrows, there is no other means than defeat, just like the previous two fortresses.

It's just that they didn't know that just a hundred steps south of the earthwork they trusted, the gate of the city slowly opened under the moonlit night, and the sound of pouring rain blinded people's ears and eyes, and in the place where the defenders couldn't see, Han Hao waved his hand under the city.

The rainy night caused trouble for everyone, including Han Hao. The only soldiers who could see his instructions were nearly a dozen people on the left, and they were the first to move forward, and the soldiers behind them moved with them, moving straight towards the position where they saw the earthwork in the daytime. Earthworks are the best counters on a rainy night, and if they can find them in the dark, they're not far from the cannon.

For the Cao army, what they lack most is time, if it is not for the shortage of time and the lack of troops, they can wait for the heavy rain to soak all the enemy's stone cannons, instead of leading thousands of soldiers and horses out of the city in the rain on a moonlit night as they are now, just to destroy the small things on the enemy's stone cannons!

They don't have the ability to destroy the stone cannon directly, usually in battle, they only need to pour tung oil and fire equipment and let it burn, but this kind of thing obviously doesn't work on a rainy night. They had to cut dozens of ropes from the stone cannons, and they also had to chisel the wooden frame in the middle, so as to destroy the stone cannons of the Yan army.

The sergeant stationed on the left side of the stone cannon did not know that the enemy had reached the vicinity, and curled up in the leather tent to warm himself by a bonfire. Suddenly, the half-asleep scout seemed to feel something in his ears, frowned and got up and looked out with his animal skin jacket, and saw that there seemed to be a figure in the heavy rain, and he hurriedly woke up the sleeping robe, and looked at each other in shock.

In an instant, the rainy night collapsed, dozens of feather arrows pierced through the heavy rain curtain, and came out of the tent, and then the knife hand rushed out, flew into the tent and fell with the knife, it was a few good big heads, and the blood was mixed with the rain on the ground in a blink of an eye.

As for the scream, it can't be heard far in the rainy night.

Han Hao nodded with satisfaction, then waved out, and the various teams that had already been prepared led their subordinates to rush out towards the stone cannons that had been pushed here left and right. Han Hao stared at the huge figure in the rain curtain and couldn't help but shake his head, who would have thought that such a thing could emit great power in wartime? If it weren't for the wrong timing, he really wanted to send someone to bring these hideous murder weapons back to the city and smash those Yan army enemies!

The lightning was like a thunderbolt, and in an instant, it was white, and Han Hao, who was stunned, suddenly came back to his senses, and only then did he seem to see a large number of armored soldiers around him...... For the convenience of night attacks, his subordinate sergeants are all lightly armoured, where can there be sergeants in armor?

Suddenly came back to his senses, but it was obviously too late, the rumbling war drums suddenly sounded around, and the rain curtain around him seemed to be all soldiers, fighting everywhere and wailing everywhere!

It's Yan Jun!

Gao Shun is similar to Lu Yi, he has not learned any tactics of military situation and military power and strategy, and he relies on nothing more than the military skills he has cultivated on the battlefield, so he is most concerned about arranging troops. Attacking Chengfu for several days, although the city was bombarded with stone cannons every night, but outside the camp of three battalions of soldiers and horses at night, the two elite trap camps took turns to take the night and day raids.

Not a single day has passed.

And on this rainy night, it was the turn of Cao Xing, who had never participated in the battle on weekdays, to be on duty at night, and his battalion was stationed west of the stone cannon. Cao Xing didn't know that the enemy army was coming, and the rain made the night march extremely difficult but also extremely secretive, but he just heard the report from his subordinate sergeants that the bonfire in the scout tent guarding around the stone cannon was extinguished, which made him suspicious, and then ordered the soldiers to run out to take a look, and sure enough, he saw countless black shadows wandering around the stone cannon in the distance, and when he got closer, he could even hear the sound of crackling, they were destroying the stone cannon!

Cao Xuan rode out on a war horse, and his subordinates had already received orders, just as the thunderbolt sounded, Cao Xuan waved his spear and shouted: "Kill!" ”
