Sa Jin watched two swarthy sky-shattering lasers shoot out, he suddenly remembered the explosion of the Qinggang Military Village, and suddenly his scalp exploded, shouting: "Get down, get down!" ”

He himself first hugged his head and lay down, but the distance between the two earth-shaking thunders was still a little too much, and the earth-shaking thunder grazed the city head and shot directly into the city, only to hear two earth-shattering explosions, and suddenly the city wall shook violently, followed by dust and black smoke.

These two earth-shattering thunderbolts landed right among the soldiers carrying stones under the city, and in an instant, flesh and blood flew everywhere, and the casualties were extremely heavy, and hundreds of people were killed on the spot.

All the soldiers shuddered and trembled their legs, a weapon of violence they had never seen before.

In the distance, the soldiers of the Song Army were also secretly surprised, they couldn't understand why this city-blasting sky-shaking thunder was only twice as large as the sky-shaking thunder used before, but it was more than five times more powerful, no wonder they all began to use this city-blasting sky-shaking thunder in large quantities to project.

Immediately after the second round of two earth-shaking thunderbolts were thrown again, the craftsman made fine-tuning to weaken the power of the trebuchet a little, one of the two earth-shaking thunderbolts fell right on the head of the city, and the other hit the city wall, and exploded under the city wall, and there were two deafening explosions, and a large pile of bricks and stones on the city wall 'boom! It poured down, causing a small gap in the city, and another earth-shaking thunder that exploded under the city wall also blew a large hole in the city wall one zhang wide, which was an effect that ordinary sky-shaking thunder could not do at all.

Li Yanqing immediately ordered: "Attack the city wall!" ”

The soldiers at the head of the city were still in extreme confusion, and the third round of two earth-shattering thunderbolts roared again, only to hear 'Bang! Bang! There were two muffled sounds, and two earth-shattering thunderbolts struck the city wall, and as soon as the soldiers at the head of the city breathed a sigh of relief, they heard two earth-shattering explosions, and a section of the city wall actually flew up, breaking in the middle, and countless stones flew into the sky, and fell again.

The earth-shattering thunder from the north happened to be thrown into the big hole that had exploded before, causing it to explode inside the city wall, and the huge shock wave blew up the entire section of the city wall, and when the smoke cleared, a five-zhang long gap in the city wall appeared in front of the Song army.

Li Yanqing pulled out his war knife and waved, "Kill!" ”

"Kill!"

The 30,000 Song troops shouted and began to rush towards the city, in front of them were 10,000 cavalry, 10,000 horses galloping, the horses' hooves beating the ground, the dust was flying, the earth was trembling, and behind were the 20,000 Song army infantry who were pressed by the black.

The defenders of the city have long been shocked by the huge power of the earth-shaking thunder, when the Song army killed, they have dropped their weapons and ran to the city, 10,000 defenders collapsed in an instant, even the slave soldiers also lost their armor, with the looted money to the west of the city to flee.

Sajin yelled and screamed, killing more than a dozen people in a row, but he still couldn't stop the soldiers from escaping, at this time, the deputy general Wang Jian ran over and shouted: "Dudu, go quickly!" If you don't leave, it's too late. ”

Sa Jin had no choice but to run down the city to turn over and dismount, and Wang Jian ran towards the west gate with dozens of cavalry.

The west gate of the city has been opened, and the slaves in the city fled in large numbers and fled in all directions, but at this time, a cavalry of more than 10,000 people appeared in the west of Xiazhou City, like a huge net, cutting off the retreat of all the soldiers.

When the main general Cao Meng saw the thousands of Western Xia soldiers fleeing in panic, he snorted coldly and shouted: "Attack!" ”

"Whew-"

The low horn of the deer horn sounded, and 10,000 cavalry suddenly launched, brandishing spears to kill the oncoming Western Xia rout.......

The Song army easily conquered the tall and sturdy city of Xiazhou without a siege ladder, and the army began to count the population of the city, going door to door searching for fugitive soldiers.

Li Yanqing was accompanied by dozens of generals to carefully check the effect of the earth-shaking thunder bombing the city, this time it did bring them surprises and surprises, Li Yanqing originally wanted to use the earth-shaking thunder to kill and injure a large number of soldiers, destroy the enemy's fighting spirit, and prepare for the next siege, but he didn't expect the earth-shaking thunder to blow up the city wall.

Li Yanqing turned around and asked an old craftsman, "Didn't this happen when you were experimenting?" ”

The old craftsman shook his head, "We have conducted countless experiments, and there has never been a record of blowing up the city wall outside the city wall, it stands to reason that the sky-shaking thunder must be stuffed into the city wall to blow up the city wall, even if the explosion-type sky-shaking thunder is no exception, this time it is really an accident, but the villain is estimated to be a problem with the city wall itself, it may be a long time, and the masonry viscosity between the stones is no longer there, so as long as one stone collapses, it will cause other stones to fall with it." ”

Li Yanqing walked to the side of the city wall and shook a big stone, which could be easily knocked down, and the masonry between the two big stones was completely crispy.

The fundamental reason is that the technology of the Xixia people to build the city is relatively backward, unlike the Song Dynasty, which used rice milk and lime to mix, and it was very strong after solidification, comparable to the cement of later generations, and this side directly used lime mortar to build the city, once it was old, the adhesion between the big stone and the big stone would disappear.

Wang Gui suddenly said on the side: "I heard that the city walls of the Xixia people were built with the help of Liao craftsmen. ”

Everyone's eyes lit up, and everyone understood what Wang Gui meant, since the city-building technology of Western Xia came from the Liao State, the city wall of the Liao State should be the same, and the Jin State directly used the Liao City Pool, so they could blow up the city wall directly outside the city wall, which was a huge discovery, which was equivalent to opening a new door to the siege tactics of the Song army.

Li Yanqing smiled slightly, "This is not only an opportunity to shake the sky, but also to hit the city wall with a battering ram, we can completely design a new set of siege tactics, which will be invincible to our attack." ”

Everyone was gearing up, full of confidence in the foreign war.

At this time, a general rushed to report: "Qiyu Dutong, General Liu has completed the inventory of the city, please enter the city!" ”

Li Yanqing nodded, then turned over and got on his horse and walked towards the city with everyone.......

Xiazhou City is the most important Western Xia city occupied by the Song army, although there are only 13,000 households, more than 80,000 people, but it is the second largest city in Western Xia, second only to the capital Xingqing Mansion, its loss means that Western Xia lost nearly half of the country.

After the Jin State occupied Taiyuan Mansion, the Western Xia also revoked a large number of military forts and garrisons on the original Song-Xia border, saving a lot of financial expenditures, but at the beginning of last year, after the Song army completely recaptured the Hedong Road, the Western Xia also planned to restore the border garrison.

Although there is no army east of Xiazhou, there are dozens of tribes living in this area, they are all border tribes of Western Xia, but their sense of belonging to Western Xia is not strong, every year Western Xia has to take out a large amount of money to subsidize them, once the Western Xia interrupts their financial support, and the Song Dynasty uses trade and food to fill this gap in time, they are very likely to become the border people of the Song Dynasty.

Zhang Shuye and Xu Huiyan's task in this northern expedition was this, they were responsible for subduing the various small tribes east of Xiazhou, and subduing them with force and food.

At this time, the chaos in the city of Xiazhou has been controlled, every household is required to close their doors, and corpses can be seen everywhere on the street, Liu Jian explained on the side: "These people were not killed by the Song army, but by the local residents, it is said that last night the Western Xia army forcibly recruited strong men, and at the same time raped and looted, so that the residents of the city hated them to the core, so when these soldiers fled into the residential area, without exception, they were killed by the angry residents, and threw the corpses, a total of more than 900 people were killed." ”

Li Yanqing suddenly found that almost all of the soldiers who were killed were Han faces, and he couldn't help but be stunned, "They are all Han?" ”

"It should be said that their ancestors are Han people, their identity in Western Xia is slaves, and they are called slave soldiers when they serve in the army in Western Xia, and they don't think that they are Han people and have pity, they don't think that their Song people can't speak Chinese, and they kill Song people to be more ruthless than the party members, so that they can turn into Western Xia civilians."

Li Yanqing nodded, this is indeed a more troublesome thing, they have encountered it before, last time they brought hundreds of thousands of Han people back to Shaanxi Road and Qinfeng Road from Weizhou and Xiping Mansion, and found that there were many people who could not speak Chinese, only spoke the party language, and later many people were difficult to adapt to because of the language and living habits, and returned to Western Xia with their families, Li Yanqing did not stop them, and let them go back.

In fact, this phenomenon is also common in history, the Sui Dynasty unified China geographically, but the huge gap between the people of the north and the south still exists, in order to bridge this gap, the Sui Dynasty dug the Grand Canal, in the economy and transportation to communicate the north and south, in order to envelop the southern scholars and create the imperial examination system, so that the southern scholars also have the opportunity to enter the ruling class.

The same is true of the Liao, Song, Jin, and Western Xia, where a large number of Han people live in these four countries, with the same ethnic bloodline, but different national identities.

There are two ways to solve this contradiction, one is to replace the residents, break up the Tangut people and move them to the interior, so that they can slowly integrate into the Song people, and the Tangut people move into the hinterland.

Another way is to forget time, with the Song Dynasty officials to manage, after a hundred years they will gradually forget that they once belonged to the Western Xia Kingdom, the premise is that the Western Xia royal family must be wiped out, cut the grass and eradicate the roots, otherwise they will be like Murong father and son, the Yan Kingdom disappeared for hundreds of years, and they still want to restore the country.
