At the beginning, Ye Qing returned to Pingliang Town in Jingzhao Mansion from the Xia Kingdom through Guanshan, and after Guanshan was captured by Ye Qing, it naturally became a subordinate town of Guanshan, and the Xia people no longer regarded the town at the foot of the mountain as their own territory.

Although Pingliang is just a small town, it has always been the first stop for business travelers who come and go from east to west on weekdays, or the last place to rest when entering the summer realm, so over the years, although Pingliang Town has not changed much, its scale is comparable to some small-scale states and counties.

And with the start of the battle of Xia, Pingliang became more and more like a military town, and it also became the place where the Song army and grain and grass gathered before Guanshan, as if it was a small Longcheng.

Before Lanzhou City was broken, Liu Keshi had already gone to Pingliang Town and began to prepare various supplies to be sent to Lanzhou.

At this time, Lanzhou City was still brightly lit, although the inside and outside of the city were tense, the city wall was also full of Xia defenders who were waiting for the battle, and the periphery of the city was full of Song troops and some siege equipment, but the atmosphere of the entire Lanzhou City was still not so nervous that people were panicked and the mountain rain was about to come and the wind was full of suffocation.

Yu Yunwen wanted to persuade Li Dezhi to surrender to the Song Dynasty without a single soldier, so as to let Mo Xiaobao rush to the aid of Liangzhou as soon as possible before dawn, and let Li Zhongfang immediately go north to Zhongwei.

Li Dezhi looked at Yu Yunwen, who came to the mansion alone, for a long time, and he couldn't react for a while, he smiled incredulously, and said in disbelief: "Lord Yu, the official didn't hear it wrong just now, right?" ”

"If Master Li has no problem with his ears, then he has heard correctly. Yu didn't say a word wrong, now that Lanzhou City has been besieged, Huizhou and Jincheng have been broken one after another, it is impossible for Lord Li to hold Lanzhou City with the 30,000 right wing troops in the city and the remnants of Jincheng. Yu Yunwen didn't seem to see the side, and the Lanzhou guard and the Jincheng guard drew out half of the waist knives that threatened him, and still calmly persuaded Li Dezhi to surrender.

"Now there are as many as 60,000 people in our army under the city of Lanzhou, and the siege weapons are readily available, and the two generals under the command of Master Li, one has just been defeated by our army, and the other is ...... It doesn't seem to have taken advantage of anything outside the city in the past two days...... Yu Yunwen continued, but his words were interrupted by the Lanzhou guard.

"Hmph, that's because you Song Jun can only run away, and you don't dare to fight me face to face. Do you think that with 60,000 people, you can take Lanzhou City, which also has nearly 60,000 people? I might as well tell you that as long as you dare to order them to attack the city, Ben will have absolute confidence that they will all be under the city. With disdain at the corner of his mouth, the Lanzhou Shou returned the waist knife to the scabbard with a swipe and said contemptuously.

"Lord Yu, don't you think that after you luckily captured my Great Xia Guanshan the year before last, you think that you have the strength to invade my Great Xia, right?" Li Dezhi only realized slightly at this time that the real purpose of the Song people this time was not to participate in the battle for the throne between Li An'an and Li Chunyou, but to take this opportunity to invade the Xia Realm on a large scale.

"Lord Yu, don't forget, almost every war between Song and Xia back then ended with your country's defeat and retreat. Why, do you really think that now that there is an opportunity to take advantage of the internal strife in my Great Xia Sect? The Jin people have not been able to enter an inch in my summer realm for many years, and now you Song people? Hehe....... Li Dezhi glanced at Yu Yunwen contemptuously, and then continued: "Don't end up, stealing chickens can't make a handful of rice, and make a wedding dress for others in vain with the territory that was finally recaptured." ”

"So, Master Lee

It is not intended to be ....... Yu Yunwen paused, still calm, glanced at the Lanzhou and Jincheng guards in the hall, and said: "Yu someone knows that now that your country's main force in Lanzhou City is complete, if you can't hold on, my Song army will definitely have nothing to do with you." But...... At this time and at that time, now the power of my Great Song Dynasty is no longer as weak as it was back then, since someone Yu dares to come alone to persuade him to surrender, he must have a perfect strategy. ”

"Then I want to see, just with your soft-footed crabs, what can the Song army, which turned around and ran away when he saw our banner, break through the impregnable Lanzhou City. Yu Yunwen, Ben will warn you, be careful that you can't go back to your Song Court because of this! The Lanzhou guard said coldly.

In the past few days, anyway, the Song army he saw was almost a group of rabble, and he didn't know how to fight for the time being, but he was as timid as a mouse, and he didn't dare to confront them head-on, and only dared to do some indiscriminate things like stealing chickens and dogs, and he was very clear.

Therefore, he didn't believe at all that those Song troops could pose any kind of threat to Lanzhou, and as for Jincheng being broken, it was just that the Jincheng guards were careless, and they believed the lie that they were just here to cheer for Li An'an.

"Do you hear that, Lord Yu? If you want me to surrender to Cheng, your army should also show some strength for me to wait for knowledge and knowledge, if it is just a mouth, you want me to surrender to Cheng, is Lord Yu a little whimsical? Li Dezhi listened to the extremely tough words of the Lanzhou guard, and his heart instantly calmed down a little, and he despised Song Jun a little.

On the night of June 5, the fourth year of Shaoxi, under the city of Lanzhou, with Yu Yunwen looking at Li Dezhi and others with a smile, and then signaled to his subordinates outside the hall, but the kung fu of tea, in the sky above the east gate of Lanzhou, three loud arrows instantly pierced the night sky, making the entire Lanzhou City instantly become tense.

"It turns out that Lord Yu Yunwen has already planted spies in my Lanzhou City, so it seems that ...... It's not been a day or two since you Song people want to beat me Lanzhou. Li Dezhi looked out of the hall slightly, while the Lanzhou guard and the Jincheng guard ran out of the hall almost at the same time, looking in the direction of the sound of arrows that had just pierced the night sky.

"Yu Yunwen, do you dare to attack the city while working at night?" The Lanzhou guard looked at Yu Yunwen, who was standing still in the hall, and asked.

"Or else?" Yu Yunwen stood up and walked out of the hall.

And almost at the moment when Yu Yunwen stepped out of the threshold of the hall, he heard a loud rumbling sound like thunder in the direction of the arrow just now, and the teacup that Li Dezhi had just put down, the lid of the cup that was not tightly lid, trembled lightly with the vibration from the ground.

"What's going on?" Li Dezhi's face was shocked, and he hurriedly looked at Yu Yunwen, who was at the door of the hall with a smile on his face.

"There are a thousand people under the command of Master Li, and someone Yu already knows about it, but it's just ...... In the face of such movements, will the Poxi Army still become a killer weapon for defending the city? Lord Li, the construction of the Lanzhou city wall is not easy, I don't want to blow it all up. Yu Yunwen beckoned to Li Dezhi.

Li Dezhi was almost like a marionette, following Yu Yunwen's gesture out of the hall, following the guards of Lanzhou and Jincheng, as well as Yu Yunwen, listening to a few long rumbling noises coming from the east, and even the ground under his feet seemed to be trembling at this time.

"...... you guys?" Li Dezhi looked at Yu Yunwen calmly in shock: "What was that voice just now?" ”

"It's just the sound of the siege." Yu Yunwen replied with a smile on the surface, but his heart was already very nervous at this time.

Three

The gunpowder and other things taken out of the thousand camps are extremely mysterious things, that is, they have not even been assembled in the army led by Li Zhongfang, only Mo Xiaobao's army has been equipped with such elite soldiers.

Therefore, when Ye Qing dispatched Li Heng and others to start attacking Xia, he separated Mo Xiaobao from Zhong Silkworm, Li Zhongfang and Tian Lin, and Yu Yunwen was still a little puzzled at first, why did he disassemble the two pairs of generals with the most tacit understanding, and thought that it was to balance them.

Now it seems that it is entirely because of the mysterious gunpowder of the three thousand battalions assembled in the hands of Zhong Silkworm and Mo Xiaobao, so that Ye Qing has to use it carefully, let Mo Xiaobao and Zhong Silkworm, cooperate with Li Zhongfang and Tian Lin, so that this mysterious firearm can be jointly owned by the two armies and become a mysterious heavy weapon for conquering the city.

And just when they were still questioning Yu Yunwen, a faint shout of killing had already been heard, and the entire Lanzhou City instantly became agitated.

In the Lanzhou Bureau, it became crowded and tense in an instant, and the Lanzhou guards and Jincheng guards glanced at each other, and then looked at Li Dezhi at the same time.

Now that the Song people have begun to attack the city, the two of them must not be able to wait here, and must immediately rush to the east gate.

"Master Li......." The Lanzhou guards had just saluted, and then they faintly heard the rumbling thunder again, but this time, it was faintly coming from the west gate behind them.

The panicked herald staggered into the Lanzhou government office, the east city gate was broken, and now it was rejecting the enemy, and the Lanzhou guard did not wait for Li Dezhi's signal this time, and immediately rushed out.

At this time, at the east city gate, with the seven thunderbolts bombing the city wall of Lanzhou together, it was just a few gaps and cracks in the solid city wall of Lanzhou, and as for the defenders who were messing up on the city wall, almost all of them were deafening explosions, and they were frightened and messed up.

The thunder is heavy and the rain is small, this is now the three thousand battalions, and Ye Qing has been able to exert the maximum power of gunpowder, the formation looks bluffing, but when it comes to effective lethality, it is not as huge as the rumbling sound at all.

But even so, the gunpowder, which had been buried under the city walls at nightfall, and the gunpowder at the gates, did not blow up the walls, but the gates collapsed after the first loud bang, forming a huge gap.

The bed crossbow arrows like spears also just finished with the sound of seven explosions, together with the huge catapult, instantly smashed mercilessly into the city wall like a raging storm, wrapped in a whistling sound, and fell towards the Lanzhou defenders who were already in chaos under the night.

The rejecting rifles originally used by the Xia defenders to resist the enemy were partly withdrawn because of Hengqiao's wandering and harassment in the past few days, either to facilitate the Lanzhou defenders to attack, or partly because Hengqiao had taken the rejecting rifles on the siege route as firewood for himself in the past few days.

When the east city gate was broken, a deafening explosion sounded at the west city gate, and then without waiting for Li Dezhi and others from the Lanzhou government office to come back to their senses, the north and south city gates also came to the deafening explosion and the Song army's shouting of killing in the siege.

At night, the walls were in flames, but outside the city was pitch black, and only shouts of killing could be heard, but it was not clear how the enemy planned to attack the city.

Compared with the short explosion at the east city gate, the explosions in the west, south, and north directions were one after another, and for a while, the Lanzhou guards who had just arrived at the east city gate were a little unclear about which direction the main force of the Song people was attacking.
