"The first two steps are the key points of acupoint exploration, and the next few steps are the key points of acupoint preparation. ”

"In the third step, the potter was ordered to fire the earthen pipe, cut it into two pieces, and put them together in the tunnel, and the two pieces were formed into a cylinder on top and bottom. The outside of the cylinder is properly coated with mud, and such shingles are installed on both sides of the tunnel, extending with the tunnel, and the tiles are close to the ground, and the chaff and charcoal are prepared in the tiles. A stove was built at the mouth of the tunnel so that it could hold seven or eight mugwort balls, and the same was true for the tile pipe mouths on both sides. The stove is equipped with four leather bellows. When the tunnels between the enemy and us were about to meet, they broke through the layer with their weapons and immediately encouraged the bellows to smoke the enemy. ”

"In the fourth step, the soldiers who were digging the tunnel were ordered to move forward with the patchwork planks, and to make holes in the panels, the size of which would allow the spears to pass through, so that they could be used to save the enemy from the damage caused to the tiles. Once the tunnel between the enemy and us is opened, the enemy is blocked with a puzzle, and a spear is stretched out from the hole to rescue the tile pipe to prevent the pipe from being blocked; if the pipe is blocked, pull the puzzle back a section of the tile pipe to block the enemy, and chisel open the blocked tile pipe to make the smoke unblocked. ”

In this way, the enemy's attack can be retreated by the method of smoking, but after the success of the first preparation, there is also a second attack to prevent the enemy, so this last step is needed. ”

"The fifth step is to bury two jars at the mouth of the tunnel, and cover the mouths with wooden planks to listen to the sound coming from the ground. Each tunnel entrance is equipped with a wooden door, inside which two tribulus terrestris are installed, and the door is equipped with an iron ring. When the enemy's tunnel is about to be connected to us, according to the situation of the enemy's tunnel and the upper and lower positions of my tunnel, dig up or down respectively to open it. When encountering the enemy in the tunnel, you can only resist and not drive the enemy, and you can even pretend to be defeated and wait for the fire to burn, and as soon as the fire is burned, you will immediately leave the enemy and enter the cave. ”

"With the above five steps, you can calmly deal with the enemy's cave attack. ”

He Liangping, who was on the side, finally knew why Qiu Guangqi looked at Shuwan differently, such a meticulous method of dealing with the enemy, almost all the situations were considered, and his thoughtfulness was indeed admirable. If he still had a complaint about Qiu Guangqi's arrangement just now, now it can be said that he is convinced.

The more Qiu Guangqi listened, the more he became fascinated, and the other people present also got to know Shuwan anew, especially Ta Mo and Xuan Tingyun, who were members of the royal family, and at this moment realized how important Shuwan's talent was comparable to that of a military advisor.

Shi Di felt that the more he listened to the art of war, the more interesting it became, and the previously mentioned Beicheng Gate and Beixue deeply aroused his curiosity, and he couldn't wait to know how the other five Beibei were defeated by the enemy, so he asked.

"What about the five preparations, such as preparing for the high proximity, preparing the ladder, preparing the water, preparing the sudden, and preparing the moth?"

Shuwan was a little surprised, she had met a lot of people who were interested in the art of war, but she didn't feel that the art of war was boring at all, and there were really not many people who could write down these somewhat obscure words in such a short period of time, and she vaguely felt the handsomeness of Shi Di. After a moment's pause, Shuwan explained.

"The so-called preparation is the way our army responds when the enemy takes a quick attack by building a high platform. In fact, if the enemy adopts this method, it can only show that their commander-in-chief is not very good at tactics, because it is really a siege method that achieves twice the result with half the effort and costs the people and money. In response to this method, we only need to raise the temporary fortress on top of the city wall, and in addition, we can also use mechs such as ballista vehicles to destroy the enemy. I will also teach the mechanics of the mecha battalion how to make the ballista. ”

"The so-called ladder is a way to deal with the enemy and climb the wall with a ladder, if it really comes to this point, it can be described as very dangerous. It is necessary to build a shelter around the city wall to contain your own troops, and dig holes in the shelter to set up catapults, ramming carts, and other equipment, and arrange elite archers between the instruments, constantly firing arrows downward, throwing boulders, throwing hanging fires, and pouring boiling water. ”

"In some extreme cases, the enemy will rely on his numerical superiority to ask his soldiers to forcibly attack the city like ants climbing a wall, and this time can be dealt with by preparing a moth. The main idea is similar to that of the ladder, but at this time conventional means can no longer fully cope with the enemy's strong attack, and some special measures need to be adopted. At this point, we can make a hovercar that can slide up and down quickly, and have the soldier stand in the car with a spear, and use this device to quickly annihilate the enemy. ”

"As for water preparation, it is a method of defending the city when the enemy breaks the flood and floods the city. Wide roads need to be set up outside the moats inside the city to prevent the enemy from flooding the city with water. In the lower parts of the city, it is ordered to dig channels, and in the lower places, it is ordered to dig deep wells so that they can be connected to each other so that water can leak out. ”

And the preparation of the sudden can only be regarded as a remedy for the failure of the city, the city wall is set up every 100 steps to set up a "sudden door", each "sudden door" is built in a tile kiln-shaped stove, and then the epithelial bellows are installed next to the door, and the stove is full of firewood and mugwort leaves. When the enemy invaded, he lowered the wheels and plugged them, lit the firewood in the stove, stirred up the bellows, and smoked the fire to roast the attacking enemy. ”

After Shuwan finished talking about the rest of the five preparations, he saw that Qiu Guangqi's eyes had changed from the original full of bitterness to brightness again, which showed that he had rekindled hope for the outcome of this battle. In terms of time alone, they only need to hold Shiyang Pass for one day and one night, and they can expect Xu Gaohan's 600,000 reinforcements, which cannot be regarded as too high. But the point is that the difference in strength between the two sides is too great, and in the face of an enemy army ten times their size, no one dares to say how much confidence they have in holding this day and night.

Now it's different, with Shuwan's seven-minded method, plus the chariot mecha mechs such as borrowed cars and crossbow carts made by the mecha battalion overnight, I believe that after tomorrow's redeployment, Shiyang Pass's defensive ability will be greatly improved, and even if it is faced with an enemy ten times its own, it will not be difficult to drag on for a day and a night.

At this moment, Yan Sing felt the star-scaled frog in his arms send out a long-lost reminder.

"Quack-quack-quack-quack-"

Before she had time to explain why she didn't join the army, she would have an internal communication beast like the Star Scale Frog, so Yan Sing hurriedly walked out of the room. Xuan Tingyun looked at Qiu Guangqi, who was a little puzzled, and opened his mouth to sing for Yan to relieve the siege.

"This is when I was carrying out the last special mission, in order to facilitate communication, I specially applied to the army. ”

Qiu Guangqi nodded absentmindedly, at this moment he didn't have time to pay attention to the origin of the star-scaled frog in Yansing, his mind was full of the conformist seven preparation methods mentioned just now, and he couldn't wait to leave the table now and start further deployment. And he really didn't endure it for long, and after about five or six minutes, he hurriedly got up and said goodbye to the others present, and took He Liangping to invite Shuwan to rush to the mecha camp.

After about two or three minutes, just as Di and the others were about to leave the table and go back to the room to rest, they saw Yan Sing walking in with a solemn face, bringing not very optimistic news.

"Canglan City, a satellite city under the jurisdiction of the federal government, sent 100,000 troops to raid Qingshan Pass, the easternmost part of the Elemental Association, which has been lost this afternoon, and the 10,000 defenders of the Elemental Association have all been wiped out. ”

It turned out that it was her deputy Crewe, who was in Le Shu Ju, who initiated the communication to Yansang. As the most lingering place for the marshals of the Liumang Building, Crewe didn't need to send anyone to spy on the news, almost everyone in Le Shu Ju learned this information at the first time. According to Yan Song's instructions, once everyone in the Earth Venerable Department obtains any information about the United Army, they must notify her as soon as possible, and Crewe had the best to fight for credit, so naturally he immediately rushed to tell Yan Song the news.

Shi Di's brows were deeply locked, of course this is not good news. When it comes to fighting, morale is the most important thing. Now that the two armies have not yet fought, the combined forces have taken a key pass from the Northland Elemental Association, and their morale has undoubtedly soared. And Qingshan Pass is lost with one block and ten, and it is easy to remind people of the current situation of Shiyang Pass's weak troops, and it is also a one-to-ten ratio of troops, so what does Shiyang Pass rely on to hold this day and night of strong attack?

Fortunately, the news has not yet reached Shiyang Pass, Shi Di thought for a while and spoke.

"Let's stop the news and wait for reinforcements to arrive. ”

But there was one person who objected, and that person was Tammer.

"No, I think the soldiers of Shiyang Pass should be let know the news. In normal times, let them know that there are two consequences of this: first, they will collapse, and second, they will fight against the water. But today, they have just experienced the pain of losing their comrades and loved ones, and they are ready to defend Shiyang Pass, so there is only one possibility to know this news, and that is the latter-a battle against the water. ”

Shi Di adopted Tamer's opinion, and the facts confirmed that his judgment was not wrong. The next day, when the news of the loss of Qingshan Pass spread to the king of Shiyang Pass, none of the soldiers said a word of discouragement. On the contrary, the expression on their faces was more resolute, and the determination in their breasts became stronger.

Cast into the place of death and then survive, fall into the place of death and then live. The potential and willpower that people unleash in desperate situations often surpass their own imagination.

On this day, Shi Di led more than 1,000 selected skillful soldiers to set up a large number of wall mechanisms on the city wall, with a total of more than 2,000 hidden arrow holes, more than 3,000 poisonous needle holes, more than 500 knife wheels and 20 mobile needle walls to prevent the enemy from forcibly climbing the wall and attacking the city.

Shu Wan led 28 mechanics who had reached proficiency in simple mecha skills to produce 50 borrowed cars and 80 repeater cars, and ordered 285 apprentice mechanics to cooperate with 120 skilled mechanics to produce 160 catapults, 200 crash cars and more than 500 suspension blocks, and placed these mecha in the corresponding positions.

The rest of the people made separate arrangements to deal with the enemy's attack according to the seven preparation methods mentioned in the book.

The day was very fulfilling, and by the time everyone returned to their rooms, the gongs had struck in the middle of the night. Shi Di lay on the bed tossing and turning, unable to sleep for a long time, tomorrow is the day of the first major battle he participated. He stood up and habitually tossed a coin, fine, face up.

The special double-sided coin reflected a silver light in the cold moonlight, and the war had finally begun.
