"I have an idea, this wall is on our side of Youzhou, if the enemy wants to build up the snow slope, let him build it up if it is a gentle slope, and our people will not have to be hit by snowballs thrown by catapults because of digging snow, causing unnecessary attrition......

"Then you're not afraid of them rushing in?"

"Senior Brother Ye, you know that there is a small lake between us and the next city wall behind us, and most of it should be frozen tightly!"

"Yes, what's wrong!" Ye Qingchou didn't understand the connection between that small lake and this city wall.

"There's a lot of ice in the lake, and we've got snow and ice here, and I think we should build something out of that. ”

"Build?" Huo Qinglong on the side also asked with some curiosity.

"That's right! We are going to use the ice blocks in the lake and ice water to glue the wall around the snow to build an urn out, so as to avoid the danger of most of the falling snowballs injuring the soldiers digging the snow, and to prevent the enemy from rushing in on a smooth road, and rushing in will also be an urn to catch turtles! And the ice must be very strong in this snowy day! As long as the ice is divided and transported quickly enough, it should actually be much faster than the stone building!" Wang Feiyu said with a gesture.

"This is also a solution, but this is not enough!" Ye Qingchou nodded, feeling that what his junior brother said now was a bit interesting.

"No, why?" Wang Feixuan looked at Ye Qingchou, not quite understanding what the senior brother meant.

"Although the lake is not far away, we don't need to turn the snow into ice, but it also takes time to transport the ice, cut the ice and build it. You must know that it is not a few days before the enemy completely lifts the ground under the wall!" "On the battlefield, the most worrying thing for the soldiers is the error of time, Wang Fei's idea is good, but at least facing the enemy's wall on the side of the snow-buried ground is not up to them.

"Then the other party is attacking with cavalry, won't he be able to get up quickly?" Huo Qinglong on the side was puzzled!

"It is indeed difficult for ordinary horses to run fast for a long time in this snowy day, Huo Qinglong, you see that it snows all year round in Youzhou, and even more so in the north, so the hooves of horses growing up here are much wider than those of horses in other states! Although this wide hoof affects speed, it is not easy to fall into it when stepping on the snow, and it is also more suitable for horses to run in the snow, and this snow slope is mainly built up by compacted snowballs, which is stronger than ordinary snow, and the horses are not so difficult to run. Then let's talk about the cavalry, the horses used by the cavalry here in winter are carefully selected, to achieve the best balance between hooves and speed, as long as the speed is a little faster, it is no problem to run a few miles or even more than ten miles in the thick snow, when the snow did not fall before, there are also places under the city walls that were covered with snow and snow earlier, do you see that the cavalry who were harassed before the initial siege was slow when they stepped on? Moreover, although the best cavalry in various countries is not large, most of its mounts are horse-like demon beasts, do you think these demon beasts are afraid of this heavy snow blocking the way and slowing down?" Ye Qingchou knew that if it was this kind of snow day, wild demon beasts generally did not like to come out to move, but this did not mean that they did not have the ability to move.

Ye Qingchou's words made Huo Qinglong have to admit that he had a specialization in the art industry, he and Wang Feiyu both thought simply, and it was not so easy to fight.

"Senior Brother Ye, I have a way to solve the transportation time, but it is a little troublesome to cut, but we can build up the snow and ice around the urn city together, so as to reduce the amount of ice cubes, and we can also use snow to cover the ice wall. As long as the snow doesn't stop, I don't believe that when the snow blows and your eyes can't be opened, he can see that this is the urn city before he comes to him!" Wang Feiyu said this, raised his eyes and looked at Ye Qingchou, and saw that he listened carefully and continued: "In addition, I also have one that is to build some ice arrow towers and other buildings that we can build with ice and snow, and build them high, if that section of the city wall is attacked, we will push the arrow tower next to it, and it is also a means to directly let it smash on the military path on the city wall." ”

"The surface of the urn city is covered with snow, indeed, carelessly, it may not be possible to see when the snow stops. Ye Qingchou nodded, "Let's go!"

"Where are you going?"

"Yes, where are you going?" Huo Qinglong, who was listening, also asked.

"Go find the king of Zhenbei and listen to his opinion on the attention of non-defeat!" Ye Qingchou said to do it, and directly took Wang Feifu and Huo Qinglong to find the king of Zhenbei.

After listening to Wang Fei's strategy and the approximate way to save time, King Zhenbei didn't say much, but just asked the general to provide Wang Feiyu with materials and manpower, and let Wang Feifei demonstrate the way to reduce time in transportation on the snow outside. After all, although there is still a way to gather a large number of people, but it is also necessary to improve efficiency and save time, this urn city is built slower than the snow slope piled by the enemy, then there is not much value, in this snowy weather, the measures of the Youzhou army to protect against the cold are generally enough! How to increase the speed is the key.

So Wang Feiyi first had to come to pen and paper, and drew his technical drawings, in fact, it is a sled, very interesting, although the north of this country is perennial ice and snow, but no one has invented sleds, skis and other equipment, in Wang Feiyi's view, this may also be related to the snow treading without a trace brought by martial arts.

In the snow under the city wall, Wang Feifei asked the generals to find the carpenter of the army, first pulled a piece of the door board he found, put something on it, and ran in the snow with light power to run in the snow for a while, fully explaining that the larger the contact surface, the less easy it is to collapse the snow; 。

"Yes, if this plan is successful, it should be credited to you. The general who provided the manpower materials nodded, leaving Wang Fei and the three of them, and went to report to the king of Zhenbei.

Seeing that the general didn't ask about cutting the ice, this made Wang Feiyu a little surprised, "Senior Brother Ye, why don't you ask about this method of cutting ice?"

"You say it's mainly transportation, and as for cutting ice, the people here know better than you and me, and the north has to cut ice every year, and then use it to store food or use it for other purposes in the summer. Cutting things you don't say they will too. After Ye Qingchou finished speaking, a large number of soldiers and a large number of local border people living between the city walls gathered in an orderly manner, some began to dig the snow and lay the foundation, others quickly took saws and mobilized wood under the guidance of carpenters to make sleighs, and an army had already set off to fetch ice!

"Do you want to go together?" said the previous general who watched Wang Feifei make a sled, and he was going to collect ice.

So the three of them followed the army to the lake, and then a group of people flew out of the lake and came directly to the ice and waved the weapons in their hands in unison, and the ice was immediately broken by the air blade......

"See, understand! There are these acquired viscera realms and innate masters who cooperate very quickly. Ye Qingchou said.

"I just didn't think of it. Wang Feiyu said with some surprise, and Huo Qinglong on the side also nodded.

"I didn't think of it, this is the army, make the best use of it, unless it is an innate refining realm, otherwise there is no such thing as holding a shelf. ”

Under the condition of not affecting the defense on the city wall for the time being, the border army gathered more than 20,000 sergeants and some wounded people who maintained logistics in the rear, and gathered more than 20,000 people. The three materials of water repaired an urn city, and no one paid attention to the snowballs that were thrown, allowing them to fly over the city wall and build up the city wall on this side of Youzhou;

It is also blessed by God, the snow is much smaller on the second day of repairing the urn city, and most of the time it becomes small particles of snow particles, which slows down the uplift of the snow slope while also reducing the resistance of everyone to repair the urn city. The defenders on the side of the king of Zhenbei increased the intensity of the arrows, and the snowballs on the opposite side sometimes did not fall accurately, and some snowballs were broken by the defenders on the side of the city wall with thicker arrows, which also slowed down part of the snow slope to rise.

Soon, at the same time as the urn city was repaired, the side of the city wall facing the Three Kingdoms was also raised to become a gentle slope that was truly passable. At this time, there were no other places in the vicinity where there were no people walking, and there were no places that were swept up by the battlefield, and the distance between the snow and the real dirt had averaged up a kilometer.

After the ground was raised, the Water Moon Kingdom and Ji Xian Kingdom began to throw some smaller snowballs, which were smaller but denser and harder, in order to press the road formed by the snow surface more solidly, so that the soldiers could charge better.

On the side of the king of Zhenbei, while fighting back, he continued to strengthen and camouflage the urgently built urn city, and the time continued to pass, and after another day, the city wall was also built up on the side of Youzhou, but it was relatively soft compared to the side facing the military camp of Jixian Kingdom and Shuiyue Kingdom. As the person who came up with the idea, Wang Feifei walked up and found that because the snowballs that came over were pressed more tightly, the foot pedal was not very deep.

After another dark night passed, the large-scale siege of Jixian Kingdom and Suigetsu Kingdom began again!
