In this era, the construction of the city walls was quite a huge undertaking. Pen, fun, pavilion www. biquge。 The amount of manpower and material resources required for info is not a small amount. Building with mixed earth is the easiest method, but it is not completed in 10 days and half a month. It is even more difficult to build a strong wall made of huge stones, such as a border fortress. From finding boulders, to chiseling stones, to building them, it takes two or three years to find them, even with hundreds of craftsmen.

In the current Luke Town, except for the manpower to prepare the tools and chores for winter netting, Snow can call on less than 80 people at most. In the face of a shortage of food, it is more difficult to build a wall than to climb to the sky in a month with the help of these 180 men who built it with earth or stone.

So Snow thought of a way, when he was chasing famous books, he was particularly fond of the story of Brother Cao's one-night city. When Cao Cao went west to conquer Ma Chao, because it was located in the Western Regions, there was sand everywhere. The fortifications that had been built with great difficulty were blown away by the strong winds. Lou Zibo, a monk of Mengmei who lived in seclusion in Zhongnan Mountain, came to the military camp to offer advice. Handed over to Cao Cao to sprinkle water to build the city, sprinkled water on the fortifications made of sand, and built an ice city overnight.

Although Snow did not prove that this method was not feasible, it was theoretically valid. And Snow believes that the method written by the rigorous Guan Zhongge should not be groundless braggart.

Snow simply changed the story of sprinkling water to build a city, replacing the identity of Brother Cao and others with the duke of the kingdom, and then told Yalian about it in combination with the principle.

"The conditions in our town of Luke are very suitable for this method, there is sand, there is water, and the temperature is also very suitable." Snow looked at Yalian, who was surprised, and felt a sense of accomplishment.

"Is this really going to work?" Although Yalian asked verbally, she already had the answer in her heart. According to Snow's approach, it is indeed possible to strengthen the wall. At the beginning, the power of her mother's ice magic was quite powerful. The power of water turning into ice, Yalian knew very well in her heart.

"I can't guarantee it's going to work, but right now that's the only thing we can try, isn't it?" Snow looked into Arlene's beautiful eyes and asked softly.

Yalian nodded and asked, "Okay, how much sand do you need?" ”

"At a minimum, increase the perimeter wall to fifteen feet high and five feet wide." Snow thought for a moment and said, "It's a lot of work. ”

"It's a tight month." Yalian frowned, "If I could, I would like to start working this afternoon." ”

"Don't worry, you take care of your injuries first. In the afternoon, I ask the residents to dig up the sand and pile it up in the livestock farm south of the town. In the evening, I will take you to the venue to remove the moisture from the sand. "The area of the livestock farm south of Luke Town is not small, and it is said to be a livestock farm, but it is actually a large open space enclosed by wooden fences.

Residents of Rook used to occasionally encircle pheasant roe deer, a rather less aggressive animal that ran into the village. But these few animals were often attacked by wild beasts, and over time, the livestock farm was abandoned, and now it can be used as a place for Yalian to dry the sand.

In the afternoon, Snow organized manpower, and dozens of residents carried sacks to the sandy land to the west, and began to transport sand to the livestock farm with puzzled faces. In the process, it is inevitable that there will be whispered complaints from residents, which is also reasonable. There was already a shortage of food, but Snow still wasted everyone's physical strength, and no one would be willing to do this kind of useless work.

Fortunately, Snow moved his dead grandfather out again, saying that his grandfather gave him an emergency solution before he died. With the credibility of the old sk as a guarantee, the big guys, although reluctant, were not good at cutting corners and playing perfunctory, and in one afternoon, two feet of sand covered the small half of the cattle farm.

After dinner, Snow and most of the other residents went to sleep, and then took Yalian to sneak away from several night guards of the escort and came to the livestock farm. Now that the temperature at night is close to freezing, looking at the sparse sandy land, Snow looked at Yalian with some anxiety, "Your injury is not yet healed, don't force it." Even if it doesn't work, we can think of another way. ”

Yalian nodded, "You stand back, I'll try first." ”

After Snow had withdrawn enough distance, Arlene took a deep breath and slowly raised her hands. She didn't see Ya Lian pinching the spell, and two clusters of dark flames appeared in the palm of her hand, and these two clusters of flames were dozens of times larger than the flames Snow had seen before.

Yalian looked at the sand in front of her, drank it gently, and waved her hands forward. The two clusters of flames went straight to the ground, and under Yalian's control, the flames spread out like a tide, evenly covering the sandy land. Immediately after that, a trace of water vapor was evaporated and slowly dissipated into the air.

It was a spectacular scene, and Snow saw the sand on the ground sizzling and white steam rushing upwards. Although it was far away, Snow could still feel the heat wave coming to his face. Fortunately, Yalian's flame was black, and if it was a normal color flame, it would definitely wake up the entire town.

The black flames penetrated into the cracks of the sand like a stream of water, completely evaporating the water inside. This process lasted for about a dozen seconds, and when the sand was completely dry, Arrene withdrew her magic. The whole person seemed to be hollowed out in half, and staggered back two steps. Snow hurriedly ran behind Yalian and reached out to hold her in his arms.

"How are you?" Yalian's face was very pale at this time, and such a large magic output obviously harmed her body.

"I'm fine, the mana consumption is too great, and I will recover after a night's rest." Yalian wanted to get up, but she didn't have the strength to do so, so she could only fall into Snow's arms with a red face. Fortunately, it was night, and Snow couldn't see his shyness.

After a short rest, Yalian stood up and said with some twists: "Go and see if the sand has dried up." ”

"Hmm." Snow nodded, came to the side of the sandy soil, squatted down and carefully picked up a handful of sand, the warmth had not yet dissipated, but the water in it had been evaporated, and it was completely up to standard.

Snow returned to Jarnene and couldn't help but praise her for her dark magic again.

The next morning, the residents who carried the sand were stunned. Overnight, the sticky sand became extremely dry. If this were in the heat of summer, it would be barely explained. But now that winter is approaching, and the temperature at night is extremely cold, how can so much sand become dry.

Snow did not answer the residents' doubts. It's just that everyone can complete the tasks assigned by themselves with peace of mind, and there is no need to ask about other things. All the tasks arranged by Snow were carried out in a confused and slightly surprised atmosphere, racing against time.
