Fu Yan was stunned when he heard this, Ma Tan's defeat back then was to be defeated on the trapped earth mountain, this is a lesson from the past! And Liu Yin chose the same strategy, which made Fu Yan a little unbelievable, with Liu Yin's cleverness, he should never make such a common-sense mistake.

"Wenxuan, Ma Tan's defeat is the defeat on this mountain, why do you ......?"

Liu Yin smiled indifferently and said, "Father-in-law thinks that if you set up a village, what is the chance of winning?" ”

Fu Yan couldn't help frowning, Liu Yin's rhetorical question made him fall into deep thought, yes, all the people denied the strategy of going up the mountain to defend after the defeat of Ma Tan's army, but who really considered the success rate of the Dao Zhai, and the Wei army on the plain head-to-head, the Shu army originally did not have any advantage, not to mention the fact that it had to face several times the enemy, such a difficulty is growing geometrically, just by standing in the village, can it really solve the problem of defending the street pavilion?

Fu Yi pondered for a moment and said, "But it turns out that if you go up the mountain to defend, it will be a dead end, because there is no water." ”

"Yes, the key is water!" Liu Yin's eyes revealed firmness and fortitude, and he said categorically, "If Ma Tan could solve the problem of water sources, he would never be defeated quickly, as long as he could hold on and drag the reinforcements of Wei to the street pavilion, the situation of the entire Northern Expedition would probably change." Therefore, the defense of the street pavilion is not a question of going up the mountain or the road, the most critical point is the water source! ”

Fu Yan looked around, except for the white expanse, there was nothing to be seen on the top of the entire mountain, this earth mountain was isolated and high, not connected with the surroundings, and there was no stable water source such as springs and streams on the mountain, it could be called a Jedi, how to solve the drinking water problem of tens of thousands of troops. Fu Yan was very dazed.

"There is a stream at the foot of the mountain, but once the Wei army surrounds the mountain, the first thing to do is to cut off the water intake route of our army, how to do it to ensure that the water source is not lost?"

Liu Yin smiled and pointed to the Quartet: "This mountain is full of water, why worry about no water?" ”

There is not much snow on the top of the mountain. It's only a few inches, but in the leeward part of the cliff, the snow can be several feet deep. Of course, Fu Tong knew that the snow would turn into water after it melted, but it was spring soon, and the snow melted, and it would be lost soon after turning into water, and it could not be preserved at all. Fu Yi had a flash of inspiration and said, "Wen Xuan means that this snow can be preserved for the garrison to drink?" ”

Liu Yin smiled slightly and said, "Such thick snow." It is simply a large natural reservoir, and as long as one percent of snow is stored, it is enough to drink 20,000 people for several months. ”

"But how do you save this snow, and how many buckets do you need?" Fu Yan said with some doubts.

Liu Yin said: "We are luckier than Ma Tan, that is, we can prepare a few months in advance, Ma Tan is fighting an encounter, and the other side to the Wei soldiers will come one after another, and the situation at that time did not give Ma Tan any time at all." He could only respond in a hurry. There is still some time before the Wei soldiers come to attack in the spring, which is enough for us to store a lot of water, grain and grass. The area near the street pavilion is densely forested. There are a lot of towering trees, cut wood to make barrels for storing water, it is very convenient, anyway, this kind of barrel does not need to move, it can be made a little bigger, made into a large wooden barrel of three feet and five feet. This allows more water to be stored. You can also build stones for the pool, there are a lot of stones on this mountain, summon some skilled stonemasons to make a large pond with a square foot, as long as the problem of old leakage can be solved. It doesn't matter how much water you store. ”

As long as anyone does not drink water for three days, his throat will be dry and smoking, and his combat effectiveness cannot be guaranteed. As long as the problem of drinking water can be solved, the task of defending the street pavilion will become easy, the Shu army is condescending, let the Wei army come to attack, Sima Wang, even if he invests more troops, he will not be able to shake a corner of Tushan.

This kind of defense is much less difficult than the village of the road, and if you think of Tushan as a city, it is simply the strongest city in the world. Fu Yi couldn't help but be a little fascinated.

Liu Yin continued: "Now that we have plenty of time, we can also requisition some pots and clay pots and other water-storing things from the cities of Longyou, these utensils are not rare, the more the merrier." In short, no matter what method is used, it is not difficult to store a large amount of water on top of the dirt mountain, and it is not difficult to defend the street pavilion. ”

Fu Yan arched his hand and said: "Okay, Wenxuan, leave this matter to me, the Dingbao Street Pavilion is solid." ”

Under the auspices of Fu Yan, a large number of carpenters and stonemasons were requisitioned and transferred to the street pavilion, of course, it was not compulsory labor, but the Shu army paid double the pay, even if it was icy and snowy, these craftsmen were smiling, and they were very hard at work. The rough work of cutting wood and taking stones was completed by the Shu army, but fortunately, the most important thing on Longshan is the forest and stones, and it is quite convenient to take local materials.

Pottery workshops in various parts of Longyou have also received a large number of orders from the military to make large-capacity clay pots, and the prices also offered are also exciting for these workshop owners. Of course, these orders are also time-limited, and now all pottery workshops have stopped producing other utensils, working overtime to fulfill the military's orders.

Truckloads of pot-bellied clay pots were transported to Longdong, although these workshop owners didn't understand what the military was doing with such clay pots, but as long as there was money to collect, they were naturally satisfied.

By the middle of the first month, when the ice and snow began to melt, the Shu army had completed the water storage target, measured by the amount of one liter of water per person per day, and the current water storage on the soil mountain was enough to support the water demand of the 20,000 army for two or three months, and if there would be rain in these two or three months, the Shu army could hold on for a longer time.

At the same time of water storage, the storage of grain, grass and ordnance is naturally carried out simultaneously, swords, guns, arrows, armor and equipment are also continuously transported to the street pavilion, Fu Tong personally urged the Shu soldiers to build fortifications on the earth mountain, cut down and take stones to make rolling wood and stones, fortunately, there are many trees and stones on the top of this mountain, inexhaustible, inexhaustible.

By the beginning of February, the arming of the entire street pavilion has been basically completed, the whole earth mountain, built as solid as gold, hundreds of bed crossbows that had been equipped in the Longyou Wei army, also Fu Yan transported to the mountain, this kind of long-range single-shot crossbow can cover and block the entire street pavilion official road, worthy of long-range attack of the magic weapon.

"General Fu, the Wei army's forward has approached Jieting." The scout hurried forward to report.

"Just in time!" Fu Yan said in a deep voice, looking at the east, dignified and confident. (To be continued.) )
