Compared with the momentum of yesterday afternoon's siege, although it was only a night apart, the morale of the military horses under Yu Luoyu's command was not to say that they had lost their morale, but the situation of not working was already very obvious. After discovering that the ladder was not high enough, the annoyed Yu Luoyu ordered the ladder to be taken back and the two were combined into one to attack the city again, but in this way, the number of people who could climb the ladder was suddenly reduced by half. And at this moment, it is still snowing in the sky, even if everyone has a sheepskin jacket, it is completely forbidden to freeze in this sudden cold weather. The most uncomfortable thing is that the head of Yunzhou City is quiet, like a dead city.

Last night, according to Du Shiyi's instructions, each city wall continued to add sandbags and splash water, the snow under the city wall has already been frozen into solid ice, at first many siege soldiers fell on the ice and gnawed mud and suffered a big loss, had to die to break the ice and chisel it, and then erect the ladder, and even for the firmness of the ladder, Yu Luoyu had to send people to support him underneath. Even so, when the first group of soldiers climbed the south wall, it was still an hour later.

The first person jumped on the head of Yunzhou City, and saw that the surroundings were empty, and half of the figures could not be seen, so he was so happy that he shouted for a while, but the next moment, a scene of joy and sadness happened.

With a bang, he fell to the ground like a heavy and heavy stone, and even slipped out of the city at once, and finally crashed headlong into the city wall not far away. However, it should have been just an experience, but this person screamed miserably, and then there was no more sound. In the face of this strange situation, the rest of the people who climbed the city wall did not have time to figure out what was going on, and their feet slipped at the same time, although some people quickly supported the city wall, but more people couldn't stop the feeling of sliding like an ice rink under their feet, some fell on all fours, and some slipped out like the unlucky guy just now. However, almost the same thing is that these people who have the misfortune to fall or hit somewhere will all let out a wail like being stabbed, and most of them will not be able to get up.

Although not many people can see this scene clearly in the city, and they don't know what is going on, but it snowed overnight, and Yunzhou City turned into a towering ice city, which everyone saw with their own eyes. I don't know which timid shouted loudly, and he was no longer willing to go up to die, and for a while, this emotion also infected the rest of the people on the ladder. As for the enemy who had just jumped to the top of the city, they were caught off guard and suffered heavy casualties, and the remaining lucky ones could not help but weep without tears when they saw the seemingly undefended city wall clearly.

The walls were frozen everywhere, and countless scattered blades flashed with sharp edges, and countless sharp blades could be seen on the frozen ground, and you can imagine the consequences of falling or bumping. It's not that this kind of thing has not been used on the battlefield, but no one thought that Du Shiyi would actually use this kind of thing in the city, and take advantage of the weather when this drop of water turned into ice, and freeze it so hard that it can't be moved, and it seems that this is not the kind of thistle terrestris that needs to be tested for workmanship, but all kinds of scraps that have been scrapped in the blacksmith shop I don't know.

Now the castle, which has been deliberately frozen into a large ice rink, has become a hell full of traps

It was only at this time that Du Shiyi, who was on the arrow tower at the head of the city, smiled. It was not in vain that people piled sandbags to build the city overnight, spread sand on the top of the city and bury all kinds of sharp iron slag, and then broke countless water to freeze it into an ice rink. He glanced at the people who were the best at archery carefully selected by him from the soldiers and people of Yunzhou City, and said in a deep voice: "Now it depends on your ability, there are so many live targets, give me a good look, I'd rather let it go than send empty arrows."

Everyone was given five quivers, fifty arrows, and hearing Du Shiyi's order, although many people were suspicious, and even secretly worried that it was because the treasury was underarmed and the arrows were not enough, but they didn't dare to ask. The road leading to the steps at the head of the city has also been completely blocked by tall sandbags. In other words, these people who jumped to the top of the city became completely prisoners trapped in cages, and they only had to aim at them.

Although aiming is not too easy in the midst of high winds and falling snowflakes, it is undoubtedly extremely easy and enjoyable to deal with enemies, most of whom are wounded. Almost after the archers had shot two quivers, there was no one left standing at the head of the city, except for one or two vigilant people who fled desperately to the death.

When Yu Luoyu learned that behind the unspeakably tall Yunzhou City, there was such a scene, even when the snow covered Yunzhou, he was still able to maintain his composure, and finally changed his color. However, when he learned that the condescending archers on the arrow tower were not so much sniping as picking up bargains, he couldn't help but show a thoughtful expression.

In this way, the defenders of Yunzhou City really suffered heavy casualties yesterday afternoon, so Du Shiyi did not hesitate to use this method as a defense. Moreover, just looking at the archers on the arrow tower, they couldn't even organize the people on the ladder to go to the city, but only made a move after the fact, which shows that either there are too few well-trained people, or there are not enough arrows, all in all, he still has a chance

"Tutun, do you want to continue to press? Just now, the loss of the north and east three sides is not small, and the situation on the three sides is the same as the south wall, the weather and location have too much impact on them, and ...... "At this moment, the person who admonished was a confidant who had followed Yu Luo for many years. He hesitated for a moment, and finally said in a low voice, "There are already some rumors in the army, saying that this heavy snow came suddenly, and the Tang army's preparation is too sufficient, as if they had expected such a heavy snowfall"

"They are not immortals, how could they have expected that there would be wind and snow," he said, but thinking of the methods at the head of the city that could only be used when it was cold and snowy, Yu Luoyu already believed it a little. However, when he thought that there were not many soldiers in Yunzhou City at all, and there were not even enough arrows, if he let go of such fat meat that came to his mouth, he would lose his troops and return in vain, and he didn't know if he would encounter other troubles on the way back to Raole Du's Mansion in this weather, he couldn't help but say in his heart, "Pass the order, and if anyone dares to talk nonsense and disturb the hearts of the army, kill and rest immediately, and then immediately attack the city again."

Seeing that the city did not retreat after gathering the military horses in a mess, and it was obvious that a second offensive was brewing, Du Shiyi couldn't help but be very happy. Whether it is another group of Turks, Xi or Khitan, this stubborn leader is so cute. Taking advantage of this rare gap, the archers are also active to resist the cold, but in such a sudden cold weather, even if they have cotton jackets to protect them from the cold, they will inevitably be cold, not to mention those enemies who are not enough to wear at all. So, when the enemy regrouped and an archer aimed at an enemy on the ladder and shot it down with an arrow, he suddenly realized something.

"Du Changshi, the actions of these captives are not as agile as before, and they seem to be a little stiff."

"On such a cold day, someone was ordered to attack the city, there are more deaths and fewer lives, who wants to die?" Despite this, Du Shiyi looked at the scattered corpses at the head of the city, and immediately instructed, "There are more and more corpses in the city, I am afraid that it will be difficult to stop them just by slipping on the ice rink, especially the main general is already red-eyed, and he is afraid that he will attack Yunzhou with a way out of the dead." Give me the order catapult to fight back"

The catapult, which had been hidden in the snow and had not been used just now, sent out a whistling stone bullet again under Du Shiyi's order. Yesterday's role was limited due to the fact that the number of catapults was not very abundant, but in this inherently bad weather, catapults played an even more extraordinary role. In particular, the stone bullets that Du Shiyi had stored in the armory workshop earlier that were deliberately polished into a round shape and had not been used at all yesterday magnified the lethality in the snow that was gradually hardened by trampling. The stone bullets rolling around not only stared horizontally, but also alarmed the horses, and for a time I saw a number of people in the army on their backs, which attracted bursts of laughter on the arrow tower.

At this moment, Yu Luoyu had already been aroused by the successive losses, he almost suddenly pulled out the saber on his body, and shouted: "If I attack Yunzhou, I will definitely wash the whole city with blood, and there will be no chickens and dogs."

His roar vaguely entered the arrow tower, Du Shiyi understood this Turkic language, and immediately ordered a specially picked out loud voice around him to shout: "Snow falls from the sky, God bless the Tang Dynasty"

With this voice, the voices of Ying He on the four walls came and went, and for a moment they suppressed Yu Luo's howl as if he had sworn by this gambling curse. Just as he was angry and about to lead his army to attack the city himself, there was a sudden commotion in the rear team, followed by a galloping horse.

"Tutun, Tutun, it's not good, it's not good" The general saw Yu Luoyu's eyes like spitting fire for a while, and he couldn't even take a breath and said loudly, "The report from the north city is coming, there are military horses galloping from the north, it seems that there are at least thousands"

"Military horses?" Yu Luoyu's pupils contracted suddenly, and he couldn't help muttering, "Could it be that the soldiers and horses of the three Turkic tribes have already arrived?" ”

Working hard, but it is possible to make wedding clothes for others, Yu Luo naturally can't swallow this breath. However, thinking that he was frustrated under the city of Yunzhou, if those Turkic soldiers and horses broke through the interception of the Yunzhou army and finally arrived, they would definitely suffer a lot of losses. Then, perhaps they might still have the possibility of uniting with each other, thinking of this, he immediately raised his hand high and ordered: "Retreat fifty steps south, and immediately find out what the situation of the military horses in the north is."

On the high arrow tower in the south city, Du Shiyi couldn't see whether there were military horses in the north, but he saw the riots of the enemy army under the city. Although he couldn't see the flags, even though he couldn't see their clothes, he instinctively knew that it was most likely the person he had been waiting for had arrived. Almost instantly, without looking back, he commanded: "Order the city gate to ambush the soldiers, and when you hear the drum as a trumpet, you will immediately go out of the city to meet the attack."
