Seven days later, Wu Yingying personally arrived in Shule with the main force of more than 30,000 Xia troops and 30,000 Gaochang troops, and the combined army of 110,000 went down to the village on three sides, leaving only one side leading to the green ridge hole. Wu Yingying was not in a hurry to attack the city, but patiently built various siege equipment outside the city, and seemed to be waiting for something. In addition to nearly 20,000 cavalry monitoring the enemy's movements, more than 30,000 infantry sergeants worked together to make various stone throwers and bed crossbows, and the progress was extremely fast.

The Black Khan army could not win the battle, and tens of thousands of troops could only retreat in the city to defend hard, and now the head of Shule City has been bombarded by the stone bombardment of the Xia army outside the city all the time, and the rumbling sound is endless from day to night, and at night, the Xia army can also use the cowhide drum to beat all night to increase the pressure on the defenders. Wu Yingying, on the other hand, led the generals to inspect the military camp every day and urged them to step up the production of stone-throwing machines and ordnance for the siege.

"There are good stones everywhere on the left side, make stone-throwing machine ordnance, sweat more, smash the enemy to death one more, and attack the city in the future to reduce the damage of the sergeants, anyway, we can't climb the green ridge in winter, let's spend it with the Black Khanate." "Wu Yingying is quite tidy, and the result of Khotan and Gao Chang's full support for grain and grass is that even if he doesn't attack the city all the time, he will surround it like this, and the first to starve to death will definitely be the Black Khan people.

Khotan and Gaochang were originally countries that hated each other, but at the moment they also passively became allies, and the Xia army joined forces to go to the village, watching the Xia army drill every day, making all kinds of ordnance, the stone thrower is only afraid that there are not tens of thousands of eight thousand, but Wu Yingying has been not attacking, Yu Khotan Wang Wei Chi Damo and Gaochang Wang Servant Guqin are a little trembling, the more the warriors of these two countries contact with the Xia army, the more they want to be like the Xia army, let the capable and prestigious warriors go to the top, and the seizures should be distributed fairly, many warriors have privately inquired whether the Xia army wants to expand the new army in the Western Regions。

A month later, when the large quantities of oil, saltpeter, sulfur, and charcoal collected by Khotan and Gaochang according to Wu Yingying's request had all arrived, Wu Yingying ordered that the armies prepare for a final decisive battle with the Black Khanate. "The north wind swept the white grass and folded, and the snow flew in August. Suddenly, like a night of spring breeze, thousands of trees and pear blossoms bloom. Scattered into the bead curtain wet curtain, the fox fur is not warm and thin. The general's horn bow is uncontrollable, and it is difficult to protect the iron clothes. This poem was written in the former Tang Dynasty, when the judge Cen Shen of Anxi Jiedu bid farewell to his colleagues, and the bitter cold scene in autumn and winter in the Western Regions depicted in it is really true.

In such a dripping and icy weather, the black sweat soldiers at the head of Shule City, whose hands and feet were almost frozen purple, had to continue to pour water along the city, and the city wall had already formed layers of hard and slippery ice, so that the soldiers of the Xia army who landed in the city had nowhere to borrow.

Under the city of Shule, since the siege of the city by the army of Wu Heroes, the Black Khan army has gone out of the city to challenge several times, and each time it has been a big defeat, and it has no choice but to defend the infant city. The army of the Black Khanate could not hold out, and the Xia army outside the city was not in a hurry to attack the city, and in addition to making ordnance during the day, it was constantly drilled. Now, all kinds of siege materials collected from Gaochang and Khotan have been piled up, and after the Xia soldiers made a large number of pottery bombs for stone throwers under the guidance of the craftsmen, Wu Yingying gathered all the generals and his subordinate armies to fight together, and it was necessary to destroy the rebellious barbarians such as Qarlu and Oghuz in one battle.

"Zhu Dao led the Iron Bone Army, the Angry Army, and the Khotanese Army to build a camp outside the south gate of Shule, lined up in a strong formation, and blocked the south gate, Bai Sheng led the Jiaorong army, the Ran army, and the Gaochang army to block the north gate, and Xiao Jiu led the Lianrui army, the flower hat army, and the Hu Yang army to block the east gate. Xingu led the hussar army, the trouble-relieving army, and the high-hoof army to stay in the camp as a response. Wu Yingying smiled and ordered the generals, "Over the past few days, the armies have prepared a lot of ordnance, and today it will be used for a while." He placed the armies of Khotan and Gaochang under the command of the Xia generals, and Wei Chi Daruma and Fu Guqin followed awe-inspiringly, at least without any dissatisfaction on their faces.

The strength of the Xia army through the Western Regions is really amazing, and the various discomforts that the Han army that usually came to the Western Regions for the first time do not seem to have happened, and even after the snow, the activities of the Xia army besieging the city are not only not affected, but even more nourishing than the black Khan in the city, Gaochang and Khotanese in the city. The sergeants wore down jackets and down pants that had been prepared by the baggage department for a long time, and their hands and feet were warmed by thick wool gloves and leather boots. This down was purchased from the south at a very low price by Fuhaixing, cleaned and selected, and hoarded in large quantities in warehouses in Hexi, and was rushed into winter clothes by the baggage workshop in early autumn, which is now just in use. Generals like Xin Gu and Xiao Jiu were wrapped in bear skins and wolf skins wrapped in their military robes, which were both warm and extremely powerful, and the sergeants of each army would burst into cheers when they saw their generals.

In addition to the people of Gaochang and Khotan, the horses and cattle and sheep carried by the Xia army themselves were rushed into simple earthen barns in time to avoid the cold, and at night, countless bonfires were burned outside the city, and the fragrance of roasted beef and mutton drifted into the city along the strong wind, which made the besieged Qarluq and Oghuz people extremely sad and depressed.

During the siege of the city, Wu Yingying in the name of combat needs, in Khotan and Gaochang army each selected and trained 5,000 elites, called the Ran Army, the Angry Army, the sergeant elected officers at all levels, appointed the former Gaochang Town General Chu Luo as the commander of the Ran Army, the original Khotanese Town General Mantur as the commander of the Angry Army, the two armies were respectively sent by the Jiao Rong Army and the Lian Rui Army to teach the rules of the army. Although the officers and soldiers of these two armies were still nominally the armies of Khotan and Gaochang, their main treatment was already on par with the Xia army, which aroused the envy of other Khotanese and Gaochang soldiers.

With the order of the general, Xia Jun's camp suddenly became active. "After waiting for a long time, the war finally began. Hussar centurion Shang Zhongxin shouted happily, seeing that victory was within reach, but the feeling of only being able to drill and wait could suffocate himself. "Obediently, if all these pottery bombs are thrown into the city, won't it become a hell?" Tu Ning, the ten-commander of the Flower Hat Army, sighed when he received the order to project all the pottery bombs. "Anyway, you can't cross the green ridge in winter, and after this battle, there are still a full months to replenish the ordnance. Cai Shun also sighed, looking at the head of Shule City, showing a look of regret on his face.

As the Xia army outside the city gates on three sides entered the preset forward camp, the curtain that was usually placed on most of the stone throwers was torn apart, and the deputy Khan Haron, who was frowning and looking at the enemy's situation on the head of Shule City, couldn't help but gasp. "Oh my God, are they trying to smash Shule City to the ground with stones?" Haron said secretly in his heart, waving his hand to order the Qarlu army to defend the city to hide behind the battlements, although this stone bullet is extremely powerful, but after all, it is not as dense as the rain of arrows, as long as it is well hidden, there are still few chances of injury, Haron looked at the soldiers of the Xia Kingdom who were busy on the stone throwing machine position with some contempt, and spat at the city.

With a huge whistling sound, thousands of stone throwers outside the city on three sides began to wield power, Wu Yingying and Xin Gu watched the battle on the high platform of the big camp together, at this time the sky of Shule City was really called a rain of bullets, but these bullets rained down, but these bullets rained down, most of the pottery bombs thrown by the Xia army were hollowed out, which were filled with the shavings produced by the stone throwers, as well as coal, hay, Rag strips and other things, before throwing out the large oil tank filled with fierce fire oil, ignited and then thrown out, after hitting the target, the clay pot shattered, the ignition of the thing splashed everywhere, a small part of the pottery bomb is the ordnance department trial production of the medicine bomb, the collected saltpeter, charcoal, sulfur according to a certain formula to make the powder, stuffed in the clay pot, left a long medicine twist outside, after hitting the target, the powder scattered, stained with sparks began to burn, and will emit an unpleasant smell.
