Therefore, Sun Hao was not in a hurry, and with a wave of the command flag, he saw another army and horse carrying a cloud ladder, bypassing half of the county seat of Shanyin, and heading to attack the city wall in the south of the county.

The southern wall was deliberately heightened when it was strengthened because the foundation of the old city wall was better. Many of the ladders prepared by the Lingnan Provincial Army are difficult to reach the top of the city wall, and only seven or eight of them can be erected to be slightly longer, and the number of Lingnan Provincial sergeants who can rely on the ladders to go up is also very limited.

In this case, the defenders of San'in Castle on the south wall had more than enough troops, and in a short time all the soldiers who had ascended the city had been wiped out, and the ladders had been pushed down.

Under the city, Sun Hao commanded without panic, and waved the command flag again, ordering the army to attack the northern city wall. This offensive was very different from the previous two times, Sun Hao sent all the remaining 20,000 or so people under his command to the north wall, and there were not fifty ladders erected, but thirty or forty. In the blink of an eye, the Lingnan army that climbed the city wall through the ladder suddenly numbered as many as four or five hundred, and it had already occupied a large section of the wall, and gradually extended to the two sections of the city wall.

It turned out that Sun Hao's previous two attacks were just feints, in order to gradually attract the troops on the city wall to the south, and take advantage of the emptiness of the defenders on the north city wall to send heavy troops to attack, trying to succeed in one fell swoop.

Such siege methods are not unscathable.

The defenders of the city seemed to be a little unable to react, and it was not until the opponent completely attacked that they sent troops from other places to drive the Lingnan army that had already reached the top of the city out of the city.

However, the Lingnan army had already gained a firm foothold at this time, and there was an endless stream of follow-up troops coming up to the city wall to support, how could they drive these horses off the city wall in a moment and a half? The battle became scorching and gradually turned against the defenders.

Suddenly, at this time, an iron cable swung down from one end of the city wall. This iron cable is more than a zhang long, as thick as a large bowl, and the total weight is more than 1,000 catties. This thousand-pound rope continued to swing along the city wall, exerting unstoppable potential energy, and destroying the dozens of ladders that the Lingnan army had erected with great effort and great cost, and it was completely destroyed in a blink of an eye.

This iron rope had been prepared by the defenders of the city for a long time, and there was one on each of the four walls, which was originally prepared to destroy the ladder. It's just that this iron rope is extremely heavy, and once it is released, it is difficult to take it back, and it can only be used once in the course of a battle, so it is only at this last resort and at the last moment that it is released, and it exerts great power.

Still attached to the ladder, the soldiers of the Lingnan Army who wanted to climb to the city wall were naturally not spared, and with the fragments of the destroyed ladder, they fell from the city wall like a kite with a broken string and autumn leaves that had been beaten by frost.

The Lingnan Army, which had climbed the wall, had no backup, but the opponent's strength was slowly increasing, and gradually the situation was reversed. These Lingnan troops were outnumbered, and after all, they could not become a climate, and a few who saw the opportunity early, hurriedly climbed down from the iron cable hanging on the city wall, and luckily stole a life to go back; And the soldiers who saw the opportunity slowly, some raised their hands to surrender, and some could only become ghosts under the sword of the defenders of Shanyin County.

Sun Haoyao, a general who was commanding from afar under the city, saw this situation and saw that the successive waves of siege that he had carefully deployed failed to defeat him, and his heart was extremely sad. He followed the king of Lingnan to fight in the south and the north, what kind of tactics have he not seen? I also know that once the iron rope of the defenders is lowered, it will be useless for a while, as long as I organize another wave of attacks, this obstructive Sanyin county town can be attacked.

It's a pity that Sun Hao now has so many soldiers and horses in his hands, and they have all been put into the attack of Fang Cai, and the morale of those who have retreated is also greatly declining, and there is no soldier in his hands. He also saw that it was getting late, and that it was several times more difficult to attack the city at night than during the day, so he had no choice but to order Mingjin to withdraw his troops, and the whole army temporarily set up camp and wait for tomorrow morning, and then make a decision.

Unexpectedly, before dawn, Zheng Yu, who was still marching halfway, sent someone to give an order, reprimanding Sun Hao fiercely, and strictly ordered him to continue the attack the next day, and be sure to capture the county seat of Shanyin.

Sun Hao originally planned to let the army rest and gather for a day before attacking, but listening to Zheng Yu's order, his tone was hard and dead, and he had no choice but to drive the soldiers again and attack the city closely.

Today's World War is not the same as yesterday.

The Lingnan Army returned from a great defeat yesterday, losing its sharpness, and the execution of the attack was slow and slow, far less sharp and decisive than before; The defenders barely held the city yesterday, their morale was greatly boosted, and they had accumulated experience in defending the city, and they were much more proficient in the use of troops.

In this way, the battle on the second day was not as fierce as the first day, and the Lingnan army could not withstand the counterattack of the defenders as soon as it reached the city wall, and was easily defeated and retreated. The defenders did not have a hard time guarding it, and they did not even use the iron cables, so they repelled the besieging troops and horses.

After the attack failed on the second day, Sun Hao organized an attack on the third day.

This attack was different from the previous two times, and it no longer played any tricks, so he simply arranged all his forces on the west wall, where the city wall was weakest, and used hundreds of ladders to make the army swarm up, hoping to break through the city by virtue of the numerical advantage alone.

Although this trick is simple, it is very practical, and the defenders in the city are afraid that the enemy will still have a rear move, so they dare not concentrate all their forces on the west wall, and in desperation, they can only use the iron cable again to break up the ladders that are full of clouds attached to the city wall.

However, after these more than 100 ladders were broken, the Lingnan Army actually erected more than 100 ladders and increased its troops to attack without discouragement.

At such a stage in the development of the battle, the defenders of the city did not care whether the enemy would still make a false shot, and concentrated all their forces on the south wall, only to defeat the frontal enemy army first.

In this way, the two armies fought inch by inch and point by point on the city wall, and they fought from early morning until noon, still without winning or losing.

At this time, the people in the city saw that the officers and soldiers defending the city had been fighting for a long time, and they must have been very hungry in their stomachs, so they stepped up their efforts to make steamed white flour steamed buns with hundreds of cages and drawers under the leadership of several old gentlemen in the city, and sent special people to send them to the city wall. When they saw that the soldiers in the city had suffered heavy casualties, they escorted the soldiers down the city and sent them to the city to be bandaged and recuperated.

It is such an inconspicuous difference that the scales of war are greatly tilted.

The defenders of the city were well fed and drunk, and when they saw that their wounded comrades had been healed in time, their morale was boosted at once, and they all shouted for joy and howled to fight for their lives against the enemy. On the other hand, the Lingnan army besieging the city fought hungry, and if it was injured, there was only one way to die, who would be willing to fight for the merits of others?

In this way, the offensive of the Lingnan army was instantly attenuated, barely supporting it for two hours, and the city wall occupied by the bloody struggle was recaptured by the defenders.

Sun Hao, who commanded the battle, was not the kind of cool general who drove the soldiers like cattle and horses, and when he saw that the offensive on the third day had fallen short, he knew that if he continued to force the soldiers to advance, it would only be a waste of troops, so he could only withdraw his troops.

On the fourth day, Sun Hao felt that there was nothing he could do, so he simply resisted the strict orders of the second son of the king of Lingnan, so that the soldiers under his command could rest and recuperate from their injuries with peace of mind, and no longer attack the county seat of Shanyin.

On the fifth day, Zheng Yu, who had been tossing and turning in the mountain road for a long time, finally arrived at the camp under the city of Shanyin County. When he saw Sun Hao, he originally held back his stomach to reprimand the lesson, but he was afraid that the old general had a long history and was commensurate with his father's brother, and he couldn't save face when he was on the spot, so he casually comforted a few words, and went back to rest.

At this time, all the troops who came to besiege the county seat of San'in had arrived, because in the siege battle of the previous days, many soldiers had been killed and wounded, so the total strength was less than the 60,000 people organized at the beginning, but there were more than 50,000 horses, and the advantage over the defenders in the city was further expanded.

From the sixth day of the fight, the operational command of the Lingnan Army was held by Zheng Yu.

At first, Zheng Yu thought that Sun Hao, a veteran, looked down on him, so he didn't command the battle very carefully, which caused the small Shanyin County to be unable to attack for a long time. However, after he took command of the army, he launched two attacks in succession, but he was defeated and retreated without even climbing the opponent's wall, and then he knew that this small county town was indeed difficult to pull out, but it was indeed a hard stone.

Zheng Yu thought of attacking hard, he couldn't compare to Sun Hao, a tenacious and experienced general, even he couldn't take Shanyin County, so it was even more difficult for him to break it, so he had to think about what strategy to use to capture Shanyin County.

At the beginning, Zheng Yu wanted to use the strategy of fire attack, and spent a huge price to pile countless firewood and grass under the gate of Shanyin County, and then poured fire oil on it. However, after the wooden gate of San'in was burned, what was seen was a brick wall that tightly blocked the city gate, and all the bricks used were the highest number of wall bricks.

Zheng Yu's failure to succeed in the first battle was just that, but it had the opposite effect, so that the good people in the county town made up a special joke to mock the enemy army, "The king of Lingnan, the second prince, there is no idea about attacking the city, and the kiln is good at firing", and sang all the time at the head of the city, so ashamed that Zheng Yu couldn't raise his head.

So Zheng Yu thought of using the tunnel excavation and siege method that the "Tianzun Sect" came from the Western Regions, and sent people to select four or five locations from all sides of the city wall and dig into the city. Although Shanyin County is located in the mountainous area, the land is still soft, and the outside of the city is under the control of the Lingnan Army, and there is no enemy attack, so the tunnel excavation is also smooth, but the tunnel is dug through one day.

But after all, Shanyin County is a small city, and now the city is full of people, and no matter where the entrance to the cave is opened, it will be easily discovered. However, the defenders in the city already knew that the Lingnan Army was good at digging sand and holes, and had already prepared a way to deal with it.

Therefore, the Lingnan army had just dug a tunnel, and what awaited them was either smoke or burial, or they dug into the encirclement of the defenders and were arrested by pointing fingers.

All in all, Zheng Yu led the Lingnan army to attack the county seat of Shanyin using the method of excavation, but did not make any progress, but wasted two whole days.

To this day, Zheng Yu, who is leading the army to fight, looks at this Shanyin county town that is close at hand but far away in the sky, as if looking at an iron broad bean that cannot be steamed, chewed, or broken, and as if there is a stone in his eye that cannot be cleaned up no matter how he kneades it, how uncomfortable and uncomfortable it is.

He remembered that the news that he was at a loss for the battle might have reached the ears of his father Zheng Gui through the army, and he couldn't help but stab him in the back. Suddenly, I remembered that the previous general Sun Hao was closer to capturing this fortified city than himself, but he still had to suffer from his repeated urging, and he felt a little guilty about this veteran.
