Gao Shun is really not in a hurry, his heart is much more relaxed than Li Dian, even if he must act as if he urgently needs to capture Chengfu City, but he is not in a hurry at all. Chengwu City is naturally very good, it doesn't matter if he can't capture it, that's not his mission.

If Cao Jun sees the people who often sit in the Chinese military tent, they will feel strange and even frightened, and the camp is clearly hung with Zhang Liao's big book, but the Chinese army tent under the big box belongs to Gao Shun...... Zhang Liao did not participate in this battle at all, Gao Shun was the supreme commander of the eastern part of Runan, and he had only one mission.

Attack Chengfu and attack the eastern part of Runan.

There is a big difference between an attack and a non-capture, especially in the terrain where travel to and from Runan is not conducive to traffic. The eastern part of Runan is just a corner, but it is also the gateway to Runan County, and the Cao army will not be happy to see the Yan clan capture Chengfu and obtain their gateway, so the answer is obvious, the Cao clan will definitely send reinforcements to Chengfu.

Gao Shun's mission is to drag Runan's already small forces here as much as he can in the process of attacking Chengfu. If the enemy is still able to defend, he must attack with ferocity; If the enemy is not strong, he will release some water to give them a little respite.

It can't be called a tiger leaving the mountain, it's just a sound attack from the east to the west, but no matter how simple the strategy is, as long as it can hit the enemy's three inches, it can still establish a huge feat.

"The camp should be set up strongly, and when we retreat, we will pass through here, so that the lives of the sergeants can be saved."

Of the three roads in the east of Runan, only Chengfu is the most spacious and easy to walk, but Gao Shun chose this road not because it was easy for him to walk, but because it was also a road that Cao Jun had to defend, and it was easier for them to send the army over.

In other words, this is a Shura field in Gao Shun's heart, burying enemies and burying his own people.

Approaching the evening, the camp is set up, the rain can be able to have the meaning of becoming smaller, the camp is thunderous with war drums, the four captains line up from under the gate to walk out in turn, nearly more than 10,000 soldiers and horses push ten stone cannons forward and backward with the momentum of overwhelming mountains and seas, and attack the city.

This southward offensive was sudden, and Gao Shun was sure that the enemy army did not have many soldiers and horses in the city. There were not many soldiers and horses, and in the face of their large-scale attack, there was naturally not much morale.

"Tonight, take the city!"

Gao Shun glanced at the camp that was still being built behind him, and was a little undecided. This camp was built on a large site, which was used for future garrisons and grain stockpiling. Of course, it is best not to use it, if they directly capture Chengfu, they will have a forward garrison city, and they will be able to gain a greater advantage in the next offensive against the Cao army.

If according to Gao Shun's idea, he would have taken down the three cities as quickly as possible and directly let his army spend the winter in Runan...... The heavy rain destroyed the roads, and the Cao clan did not have the opportunity to transport all the grain and grass from the various cities in the autumn, so they could get enough food and grass and time for the soldiers to recuperate. After taking the city, drive the people of the city to the north, so that the city becomes a military town; Or let the people go to the west to eat Cao Cao's grain, it was just a thought.

After doing this, in the spring of the next year, we will directly send troops to capture Runan, only three battles at most, no, a decisive battle can decide the ownership of Ruyin, and then the west of Runan will not even need to fight to be attacked by the wind and rain.

It's just that Zhang Liao didn't think so, and at the beginning of this war, it was decided that Gao Shun could only be a foil.

The world is changing, but some things are always the same.

This was the first time Gao Shun had commanded such a large army on his own, and he was eager to make a feat rather than be a foil. But he also had no way to disobey Zhang Liao's order, and could only hope that the Cao family could send enough soldiers and horses to help Cheng's father.

The siege begins!

The lion fought the rabbit with all his strength, although it was only a small city that needed to be faced, Gao Shun also used enough strength, more than 11,000 people from the four captains' departments, and ten stone cannons were stacked at the front of the battle array.

This is the maximum force that can be spread out by the existing terrain.

The defense of Li Dian was not weak, but it seemed that it was a certain situation for the Yan clan to bombard the city with stone cannons before attacking the city, so they did not rush back and attack, but let the soldiers hide behind the city wall, relying on these to avoid the bombardment before the Yan army attacked the city.

When enough stone cannons are in Zhang Liao's hands, they can play a decisive role in the siege of the city, such as Zhang Liao's strong attack on Qiaoxian County, directly using hundreds of stone cannons to collapse the city wall and break a road; More often than not, however, the cannons were only used as an auxiliary in the siege, shortening the distance between the besieging army and the city walls, so as to cover the siege soldiers carrying ladders from the arrows fired from the city.

Huge stone bullets bombarded the city wall with unparalleled might, and the rammed earth wall shook violently, mixed with the sound of the wooden fence shattering, and the broken thorns shot out of the dust, and the sound was terrifying. It was only terrifying, but what was truly terrifying was the inaccurate boulders that climbed over the walls of the wooden ramparts and smashed into the ranks of the guards with a strange roar...... The living soldiers were crushed into pulp in the blink of an eye, and the soldiers who were directly hit could not even let out a wail before they were turned into stumps, severed arms and a puddle of minced meat.

A considerable part of the Chengfu defenders are veterans who have returned from Yanzhou, after all, this is already a 'frontier' for the Cao family, as the oldest and most elite veterans who have experienced the battlefield, there is no situation in the past where the army's heart collapsed as soon as the stone cannon came out, and more of the soldiers who were lucky enough to avoid the stone bullets were against the shaking wall, and they were accustomed to life and death looking at the robe that was crushed into flesh, and questioned with resentment.

"Why does the Yan clan have this weapon, but we don't?"

"Why is the Yan clan attacking us, but we can only defend the wall?"

There is no answer, because everyone has an answer in their hearts, and all that remains is to grit their teeth and wait for the hand-to-hand battle to fight.

The stone cannon bombarded his head, but Li Dian was not afraid, and climbed the wall as usual to watch the attack of the enemy's foot soldiers. This was not the first time he had fought against the Yan army with stone cannons, and with the frequency with which the stone cannons bombarded the walls, he was able to easily estimate the number of stone cannons used by the Yan army...... No more than twenty, and in a moment, only twenty stone projectiles flew in, and even fewer hit the wall, and the chance of hitting him was even smaller.

With just a glance, Li Dian realized that the Yan army's stone cannons had a longer range and greater power than theirs.

Fortunately, however, the enemy's foot soldiers carrying the ladder were about to enter 300 paces away.

"Foot archers withdraw from the wall, three hundred steps, release arrows!"

With Li Dian's order, more than 1,000 archers withdrew from behind the wall in an untidy manner, taking a huge risk to pull their bows and wind them, and the arrows shot vigorously!
