The Western Xia soldiers were tired on the march, their morale was low, under the fierce attack of the Song army, the Western Xia soldiers were in a big mess, and the team soon collapsed, at this time, as the two gunpowder arrows exploded in the sky, the dust suddenly flew in the distance, the earth began to tremble slightly, and soon the dust covered the sky and the sun, and the eight thousand cavalry led by Wang Gui were overwhelming from two miles away.

"Arrays are fighting!"

"Arrays are fighting!"

Gao Tingyi, who was in the front army, shouted loudly and ordered the soldiers to resist in formation, but at this time, the morale of the army was completely shaken, and the soldiers began to flee for their lives, and only more than 1,000 people responded to his call.

"General, it's cavalry! The cavalry is coming! A soldier shouted in fear as he pointed at the sweeping cavalry.

Gao Tingyi's scalp was numb for a while, he looked back at the army, the army had already scattered and fled, only more than a thousand people followed him, he sighed in his heart, and shouted: "Retreat with me!" ”

He turned his horse's head and fled in panic in the direction of Luocheng with more than a thousand soldiers.

Wang Gui's cavalry did not pay attention to them, they scattered in all directions, and began to mercilessly pursue the Western Xia soldiers in the moonlight, the desert was full of the corpses of the Western Xia soldiers who were hacked to death, for a time the corpses were all over the ground, the blood flowed like a river, the pungent bloody breath filled the entire wasteland, and the wolves howled excitedly in the distance.

The war ended after an hour, most of the Western Xia soldiers were killed by the Song cavalry, only a few soldiers fled the battlefield, the Song army cleaned up the battlefield a little, Li Yanqing led more than 10,000 soldiers back to the Weicheng camp, Wang Gui led 8,000 cavalry to Luocheng to meet Niu Gao's army.

At this time, Gao Tingyi had learned the news that Luocheng was attacked and captured by the Song army, he was shocked and angry, but he was very scared, and he didn't dare to stay longer, he sent a soldier to Weicheng secretly to deliver a letter, and he led more than a thousand soldiers to flee to Xiacheng, hundreds of miles to the east, as for how to solve the problem of military rations on the way, he himself did not know.

………..

The defenders of Weicheng received the news of the annihilation of 20,000 reinforcements in the afternoon of the next day, which shocked Chaka, and he immediately used a letter eagle to urgently report to Xingqing Mansion, and at the same time ordered the defenders to stand by, he knew in his heart that the next target of the Song army must be Weicheng.

Night fell again, Li Yanqing looked at Weicheng from afar, and wondered if he could knock on the door of Weicheng tonight? Li Yanqing's heart was full of confidence in tonight's battle.

Any city will have holes in its defenses, and the first factor in attacking a city is not how powerful the siege weapons you have, but whether you find a hole in the city's defenses.

Weicheng was built on the mountainside, the slope is high and the city is steep, easy to defend and difficult to attack, it seems to be invulnerable, but for the experienced Li Yanqing, the first time he saw Weicheng, he found the biggest weakness of Weicheng's defense, that is, the city is too small.

The circumference of the city was less than four miles, and the east, west, south, and north were less than one mile each, which meant that there was no strategic depth and it was difficult to resist the saturation attacks of the enemy.

As early as the time when Li Yanqing arrived in Western Xia, ten heavy trebuchets were transported to the front-line barracks in the form of dismantling parts, and 100 craftsmen installed the ten heavy trebuchets in just one day.

Under the cover of night, ten heavy trebuchets began to slowly move in the direction of Weicheng, this kind of heavy trebuchet is two feet six feet high, and the throwing rod is five zhang long, which can throw a hundred catties of heavy objects to two hundred paces away, and if the weight is reduced to fifty catties, the range can reach three hundred and fifty steps.

Although there were also a dozen miniature trebuchets on the Acropolis, the targets of these trebuchets were mainly enemies attacking the mountain, and the throwing distance was up to fifty paces, and they could not threaten the heavy trebuchets at a distance.

Unless the Western Xia army uses bed crossbows, even if the Western Xia army uses bed crossbows, the Song army also has a perfect countermeasure, not to mention that the Western Xia does not have the bed crossbow This is the most long-range strike weapon, at most there is only a military crossbow with a range of one hundred and fifty steps, and in the face of the Song army's long-distance attack, the Western Xia army can be said to be helpless.

The Song army set the position of ten heavy trebuchets at two hundred paces away, shooting on the back here, and could easily throw fifty catties of heavy objects into the city, although knowing that the Western Xia army had nothing to do about the attack two hundred steps away, but the general Liu Ziyu still ordered to build a fence, the so-called fence is to use sandbags to build a sandbag wall in front of the trebuchet, two feet high, as long as one mile, the Song army threw upwards without hindrance, but the downward shot at the head of the city will be effectively blocked by the sandbag wall.

Liu Ziyu took the initiative to ask Ying, and he led 5,000 troops to become the main force to attack Weicheng tonight, but the entire attack plan was drawn up by the commander Li Yanqing, and Liu Ziyu must implement the established plan to the letter.

Ten heavy trebuchets creaked away behind the sandbag wall, and ten earth-shaking thunderbolts were placed in the steel pockets, which were only the first step in the attack, with the aim of destroying all the stone buildings in the city, but the real blow was the second step.

'Boom! Boom! Boom! Boom! With the sound of fierce drums, the Song soldiers lit the arquebus, the trebuchet fired, the pole was swung out like a long arm, and ten black earth-shattering thunderbolts rose into the air, flew over the heads of the defenders, and fell into the city.

Ten earth-shattering thunderbolts exploded one after another in the city, the explosion sound was deafening, and gray-black gunpowder smoke rose into the air, connecting in the sky, enveloping the entire city.

Immediately after that, the second round of ten ignited earth-shattering thunderbolts were thrown into the city, and the city exploded with a bang, like a muffled thunder in the clouds rolling over the city, and the pungent smoke filled the whole city, and after only two rounds of explosions, most of the houses made of stone and wood had collapsed, and thousands of soldiers panicked and rushed to the corners, only by hiding in the corners of the walls, they would not be buried by the collapsed houses.

The Song army launched five rounds of earth-shaking thunder attacks, fifty earth-shaking thunders almost leveled all the buildings in the city, and even the beacon tower collapsed in the third round of explosions, and after the five rounds of explosions, the Western Xia defenders suffered nearly 1,000 casualties At this time, the Song army began the second step of the strike, attacking Weicheng with fire.

The Song army attack has its own rules, much smarter than when the Jin soldiers attacked Tokyo, 3,000 crossbowmen held the god arm crossbow and raised the shield to squat down a hundred steps away from the foot of the mountain, cover themselves with a huge shield, and at the same time ignited the fire oil on the arrow with a fire fold, and one rocket after another began to burn, at this time, ten trebuchets launched rapidly, throwing ten fire oil canisters into the city.

This kind of oil pot is a kind of thin-skinned clay pot, which weighs 50 catties after being filled with oil oil, and the biggest feature of this kind of clay pot is that it is not strong, even if it falls from a height of three feet, it will be broken, let alone thrown from a high altitude outside the city.

At the same time that the ten oil canisters were in the air, three thousand crossbowmen launched rockets into the city together, this plan was formulated by Li Yanqing, he mainly considered that there might be someone in the city to be responsible for extinguishing the fire, of course, the rocket and the oil landed at the same time, even if there was a special person to extinguish the fire, it would be too late.

At the same time as the canisters flew towards the city, the sound of shooting sounded, and three thousand soldiers raised their crossbows and fired three thousand rockets into the city, and the army immediately retreated like a tide.

Three thousand rockets rained down on the city like a swarm of fireflies on a summer night, causing a sea of fire in the city, with shards of broken pottery and spilled oil everywhere in the city.

As for the special fire-fighting soldiers that Li Yanqing was worried about, there was no trace at all, not to mention whether they could survive the repeated explosions, and more importantly, the specialized fire-fighting soldiers would only be prepared if they experienced a tragic battle like the Battle of Tokyo.

The ignition of the oil made the extinguishing meaningless, and then the second, third, and fourth rounds were ....... The fire burned all night, and the Song army threw hundreds of cans of fire oil into the city, so that the entire Wei city was engulfed in flames.

At dawn the next day, the whole city was still shrouded in black smoke, but there was no defender soldier in sight on the city, dozens of miniature trebuchets on the city were burned to ashes, and the city gate was also burned to a thousand holes, only a pair of shelves were left in front of the city gate, as long as it was gently pulled, it collapsed, but in the end it saved the trouble of the Song army, not long after dawn, there was a muffled sound, the city gate fell straight down, fell into pieces, and a lot of black charcoal that was still burning rolled down the mountain.

The gate was opened, so that the soldiers of the Song army could clearly see the situation in the military city, the military city was full of stones, it was dark everywhere, the city gate in the north also disappeared, the north and south gates were opened, the strong north wind blew in, the air was full of black powder, and if you were not careful, your body would be covered with a layer of black ash.

Until noon, Liu Ziyu personally led a team of soldiers to enter Weicheng cautiously, the ground was still warm, but there was no defender in the city, and not even a complete weapon could be found, but in addition to the disappearance of the city gate, the entire military city wall remained intact, and the earth-shattering thunder did not fall on the city.

Not long after, the soldiers sent by Liu Ziyu reported to Li Yanqingyu: "Qiyu is in charge, there is no enemy soldier in the military city, and the ground of the city gate is no longer hot, you can enter!" ”

Li Yanqing nodded and said to the soldiers: "Go and tell General Liu to clean up Weicheng before dark!" ”

He then ordered Wang Gui: "You can lead 8,000 cavalry to attack Xiping Mansion, there are no defenders there, you must occupy it for me!" ”

"Obey!"

A quarter of an hour later, 8,000 cavalry under the leadership of Wang Gui and Cao Meng left Weicheng and rushed towards Xiping City, which was hundreds of miles away.
