Wu Haogu, Gao Yu, and Tong Guan were surrounded by a large group of knights, and they had already seen the white city wall of Tongwan from a distance. It is said to be made by mixing steamed Sanhe clay with glutinous rice juice and ramming it. In order to ensure the durability of the rammed earth, Helian Bobo used brutal supervision methods while building the city, using iron cones to inspect them, killing anyone who penetrated an inch and filling the walls with corpses. But if the cone does not enter the wall, he shall kill the one who acts as an examiner.

Therefore, the city was built extremely strongly, and it is said that when it was first built, the city walls could be used to sharpen swords!

It's just that I don't know if the white city wall of Tongwan can block gunpowder after 700 years of wind and rain?

Looking from the banks of the Heishui River, the Tongwan City in the distance has obviously been renovated, and it doesn't look like a 700-year-old antique. The white walls were covered with layers of guards, and the horses-faced walls were covered with sharp wooden stakes. Outside the city, the four checkpoints are piled up and fierce, and there are a lot of guards at the head of the city, and the armor is distinct, so you can know that this place is well guarded at a glance.

However, this situation is not surprising, this is originally the largest barrier for the western thieves in the Wuding River and Hengshan area. These days, God knows how many supplies and people have been transported from the various castles along the Wuding River, as well as from the oases and grasslands near Tongwan, and I am afraid that there are a staggering amount of grain and grass materials piled up in the city. If this city was captured by the Song army, the western thieves would have nothing to fight along the Wuding River. Let's retreat directly to Yanzhou!

When Wu Haogu, Gao Yu and Tong Guan were watching Tongwan City, there were also many infantry cavalry of party members on the other side of the Heishui River who were staring blankly at the Song army that was slowly unfolding.

These party soldiers had frightened looks on their faces, and many of them were already retreating in the direction of Tongwan City. For they saw a cavalry of more might than any of the best men of the party they had ever seen!

This cavalry is the cavalry of the royal horse in front of the palace.

1,000 armored cavalry, divided into 20 squads, spread out on the left and right of Wu Haogu and others. They did not rush to the shore, but stopped four or five hundred paces from the river beach, and then everyone turned over and dismounted. Just standing there wordlessly!

Everyone knows what they're doing? It's accumulating horsepower! The horses they were leading knew at a glance that they were good horses that could rush up. Isn't there no good horse in the Song Kingdom? Where did they get their horses?

That's a thousand horses...... Wrong! They seem to have an auxiliary retinue behind them with a deputy horse!

At least 2,000 horses! The cavalry of the Song people is so generous!

The general of Western Xia, who is also the Wuyi Boma of the Horse Master, was also watching on the west bank of the Heishui River at this time. When he saw the armor rider on the other side of the river, he immediately gasped.

No wonder His Royal Highness the King of Jin is so jealous of the Song people's armor horses, they are really elite! At least there were no cavalry in the hands of the Vultures who could fight them.

But...... No matter how strong the cavalry of the Song people is, can they still climb the city wall? Thinking of this, Wuyi Boma frowned slightly, how did it become that the cavalry of the Song people was strong now, and the city of the Great White High Kingdom was strong?

Wu Yi Boma shook his head, pulled the reins, turned the horse's head, and galloped towards the impregnable Tongwan City with his guards!

"Chongdao, Tongwan City is not small, can you dig a long trench in fifteen days?"

Tong Guan also frowned a little, because Wu Haogu did not bring the people with him when he sent out the army, only more than 5,000 auxiliary soldiers who were responsible for transporting grain and grass. Even with the addition of 5,000 pikemen and 2 sapper commanders, the maximum number is 11,000.

With such a small number of people, it may not be easy to complete the long trench of the siege in 15 days, right?

If the long trench can't be dug completely, Wu Haogu will inevitably be punished - Wu Haogu this time, like last time, signed a contract with Tao Jiefu on the grounds of the contract, and also took 100,000 yuan of "engineering fees", if it cannot be completed by the expiration date, the compensation alone is 3,000 yuan a day. Moreover, Tao Jiefu issued a military order, and if he can't complete it, he will be punished!

"Of course you can dig it!" Wu Haogu said with a smile, "There are 10,000 people, and the contract doesn't say how wide and deep the long trench should be." ”

What does it mean? You're going to cut corners, huh? Tong Guan thought to himself: Now is not the time to be a profiteer!

Gao Yu also shook his head and said, "Da Lang, if this long trench is not dug deep and wide enough, I am afraid that it will not be able to trap the western thieves in Tongwan City!" ”

"Why trap them?" Wu Haogu smiled, "Won't it be enough to take the Tongwan City!" ”

"Take Tongwan?"

Gao Yu thought it was incredible.

Tong Guan remembered something, "Chongdao, do you want to blast the hole?" ”

Wu Haogu nodded: "Yes!" It's a cave blast! Blow up the walls of the city...... We have 10,000 infantry soldiers in our hands, and 5,000 of them are still dragon warriors, so I don't believe that the western thieves who defend the city can resist it! ”

"Cave blasting?" Gao Yu had never heard of this term, "Can you still break through the city wall?" Really? ”

Wu Haogu smiled: "I'll know in more than ten days!" Shiyan, I am tired of your cavalry to stay for a few more days, and give me a foothold. ”

"Okay!" Gao Yu said with a smile, "Foolish brother also wants to see how this Tongwanjian City is broken!" ”

……

"Sons, kill with the old man, kill a wife and shadow son!"

"Wan Sheng! Wansheng! Wansheng! ”

With the shout of the old military strategist Wang En, everyone cheered for the army of Yanyan Road that had just been launched under Longzhou City.

Their cheers were not without reason, because the city defense of Longzhou City looked very empty. The low, dilapidated walls were sparsely populated with flags, and there were few defenders and guards. The ditches outside the city were shallow, narrow, and dry and waterless.

Such a defense could not withstand the attack of the 28,000 people of the Yan Yan army (including the accompanying foot soldiers).

In addition, the defenders of Longzhou not only had few numbers, but it also seemed that there were no light cavalry available. In the face of the surging Song army, they didn't even fight the outpost battle between the scouts and cavalry, and all of them retreated into the castle. Let the Song army approach and set up a continuous camp position, stabilize the position, and expand the brigade.

Seeing the high morale of the whole army, Wang En nodded with satisfaction, and said to his son Wang Ze: "Ze'er, are you ready to choose a striker?" ”

"Back to my father, the child has prepared 1,000 selectors, all of whom are the elite of my Yan Yan army, everyone is determined and persistent, and the ladder shield car is also ready to attack the city at any time!"

"Good!" Wang En touched his white beard, "What about the soldiers in Hengshan?" ”

"3,000 strong men, all ready with swords, shields, bows and arrows!"

"Good! Pass the old man's order. Wang Endao, "Let Hengshan Fan push the shield cart to take the lead, and let our selectors follow behind to press the formation." ”

"Order!"

Of course, the old military strategist understood the great principle of national unity, so he gave up the glorious and arduous task of taking the lead to the Hengshan soldiers.

Li Yan, who led the way for Brother Cha in the month of last year, has now become a general on the side of the Song army - the tribe under his father's jurisdiction also sent people to follow Brother Cha to invade Yan'an Mansion, so his father's big leader has also come to an end, and he was called by Tao Jiefu to live in Yan'an City under Pagoda Mountain. And Li Yan took over as the new leader, and also got an official position as an inspector. Now with more than 200 sons of his family, he follows Wang En to fight Western Xia.

This young leader of the Tibetan tribe, who was disgusted with the Great Song Dynasty and loved the Great White High Kingdom, sounded the drum of the march in his ears. The Song army Xuanfeng, who was wearing armor and holding swords and shields, and the Song army crossbowmen who were holding bows and crossbows, had already set up a formation behind Li Zhen. These people are not here to cover the Tibetan warriors, but to supervise the battle!

If Li Zhen and his sons dare to defect, they will not even be able to advance. Then you have to taste the iron fist of the Great Song Dynasty national unity!

"Sons! Lift the ladder and push the shield cart...... Forward! ”

Even though Li Yan was unwilling, he still gritted his teeth and ordered to attack.

Because of the rush of time, and Yokoyama's life was not worth much in the eyes of the soldiers of the Western Army. Therefore, Wang En and Wang Ze did not prepare decent siege equipment for them at all, but they nailed the big wooden shield to the board cart for transporting grain to make a shield cart, plus some ladders, and let the Hengshan fans take the lead.

In addition, there were sacks of earth piled up on the shield carts, which were used to fill the trenches. So it's very hard to push. A shield cart is pushed by seven or eight people, and it can only move slowly.

Behind the shield cart, there was a ladder carried by seven or eight Tibetan warriors. They carried a wooden shield in one hand and a ladder in the other, and walked forward with their heads covered.

When the warriors pushing the shield cart filled the trench, it was their turn to risk their lives to erect the ladder!

And Li Zhen led the strongest warriors, each with a little armor on their bodies, a shield in one hand, and a sword in the other, following the warriors carrying ladders.

When the ladder is erected, it's their turn to climb up!

Climb up and meet your former compatriots......

The young Han Wu also put on iron armor at this time, holding on to the sword and shield, and walked behind Li Zhen with a snort, looking at the low Longzhou city wall with red eyes.

There is a head of a party thief in the city!

Just chop a few...... Cut down dozens of them, and you can become an official! It shouldn't be that hard!

……

On a wooden map, Brother Wei Ming Chage saw the latest situation of the Hengshan-Wudinghe battlefield.

One of the Song troops who came over Hengshan has arrived at the foot of Longzhou City! It's already under siege!

He let out a long sigh, Longzhou couldn't hold it...... Not only Longzhou could not be defended, but Hongzhou at the northern foot of Hengshan was also undefended. A series of fortresses such as Guwuyan City, Helan Yuan, Sanchakou City, Shenliudui City, and Prince Well north of Hongzhou and Longzhou could not be defended.

But the Song people don't want to occupy the territory easily. For he not only left some of the party's warriors in these castle strongholds. In addition, there were some Hengshan Qiang people who swore to follow the Great White Gaoguo to the death were scattered in the ravine at the northern foot of Hengshan, waiting for the Song army to pass over, and they could jump out and cause destruction.

In this way, the Song army must stay behind to defend the city, and the troops placed on the front line will be greatly reduced......

By the time they besiege Youzhou, the opportunity to counterattack has arrived!
