The smoke-singing person can be used by them, and this is probably the only good news they've heard these days. Despite this, under the shadow of the war, the air pressure inside the ink bird was still a little low.

Under such low pressure, the ink bird carried the group back to Shiyang Pass. Due to the heavy damage of Bill, the flying speed was obviously lower than usual, and the original trip of more than ten hours flew for more than a day, that is, it was only two nights and one day before the 300,000 troops led by Keynes arrived at Shiyang Pass.

At this time, the 600,000 reinforcements led by Xu Gaohan still needed two days and one night to reach Shiyang Pass, which was now only guarded by more than 60,000 soldiers, which could be said to be precarious.

The soldiers of Shiyang Pass have been waiting for the battle, and all of them are ready to fight with Wang ** to the end with the determination to see death as home.

Except for Xuan Tingyun, Shi Di and others have never joined the army, nor have they experienced any wars, so they can be said to know nothing about war, but there is one person who is familiar with military books, especially proficient in the law of conformism.

That night, Qiu Guangqi set up a banquet to entertain Shi Di and others, saying that it was a banquet, but there was a sense of tragedy everywhere during the banquet, Qiu Guangqi didn't speak, just bowed his head vigorously and drank stuffy wine, there was not much time left for him, tonight may be the last indulgence.

At this time, Shuwan stood up, first toasted a glass, and then asked.

"I wonder what kind of deployment Lieutenant General Guangqi will deal with the enemy this time?"

Qiu Guangqi was slightly surprised, he didn't know what kind of medicine was sold in the gourd, he glanced at Xuan Tingyun with an inquiring eye, and the latter nodded at him slightly, indicating that he could answer truthfully, and then replied.

"This time, the difference between the strength of our army and the enemy army is too great, and since ancient times, the method of winning more with less is nothing more than skillful use of terrain, attacking and defending each other, attacking the east and attacking the west, retreating as advance, attacking with elite troops, and sinking the boat. Among them, in view of this battle, there was no feint attack near Shiyang Pass, so it was impossible to attack the east and the west; Shiyang Pass was the first important pass, and it was absolutely impossible to lose it, so it was impossible to retreat into advance; and according to our intelligence, the other side had already deployed heavy troops in the main camp and supply battalion, so it was impossible to make a surprise attack by elite troops. ”

"Therefore, this time, we have made a deployment with the key points of skillful use of terrain, attacking and defending, and breaking the boat. First of all, Shiyang Pass is easy to defend and difficult to attack, and the geographical advantage is obvious, we have repaired the trenches and watchtowers, prepared excellent defensive equipment, and built another gate outside the city gate for defense, which is a clever use of the terrain. Secondly, in addition to the weapons of defending the city, we have also prepared weapons for attacking the enemy, building a fence to connect with the city wall, and preparing archers to shoot the enemy, and placing some long and short soldiers every five meters on the city wall, and also equipped with iron thistles, stones, rolling logs and other equipment everywhere, which is a combination of attack and defense. In the end, I myself have signed a military order, and more than 60,000 soldiers have already prepared to become benevolent if they do not succeed. ”

Shuwan looked very focused, but after listening to Qiu Guangqi's words, she frowned slightly and continued to ask.

"I wonder if Kannai is prepared for the enemy's cave attack?"

The look of surprise on Qiu Guangqi's face became more obvious, and he couldn't help but secretly marvel in his heart. Due to the lack of cave surveyors who are good at exploring the location of cave attacks, Shiyang Pass's defensive strength in dealing with the enemy's cave attack is indeed very weak, I didn't expect that this Qianqian woman in front of her actually said a word, so quickly saw the weakness of Shiyang Pass's defense, sure enough, people can not be disguised, and their people must have studied the method of defending the city, it is better to ask her for advice or two. Thinking of this, Qiu Guangqi hurriedly spoke.

"It seems that this girl has studied the art of war, please give me some advice. ”

"Don't dare, just a little bit of it. My Mohist family pays attention to the concept of both love and non-attack, and has always been opposed to the unjust war, so I have studied a set of methods to defend the city to deal with the unrighteous army, but it is a pity that it has been lost for a long time, and a large number of articles have been unexaminable, and only seven methods have survived. One is to prepare the city gate, the second is to prepare the high line, the third is to prepare the ladder, the fourth is to prepare the water, the fifth is to prepare the sudden, the sixth is to prepare the hole, and the seventh is to prepare the moth Fu. ”

"Oh, how about the way to prepare the city gate?"

"The commonly used siege methods are nothing more than proximity, hook, rush, ladder, moat, water, hole, sudden, hollow, ant, yi, xuanche twelve kinds, that is, building mountains to attack, hook ladder to climb the city, rushing to attack the city, cloud ladder siege, filling the city ditch, flooding the city, tunnel siege, penetrating the city wall, digging holes in the city wall, climbing the city like ants, using four-wheeled vehicles covered with cowhides, and using towering Xuan cars. Strategically speaking, the following 14 factors can determine the success of the defense of the city: the city wall, the ditch, the watchtower, the defensive equipment, the grain and firewood, the number of defenders, the relationship between the government and the people, the number of meritorious heroes, the faith of the monarch, the location of the ancestral tomb, the mountains, forests and grasslands, the topography, personal wishes, and the reward and punishment system. ”

According to what Lieutenant General Guangqi just said, among these 14 factors, our army has the advantage of high and thick city walls, deep and wide trenches, abundant grain and grass, harmonious relations between the government and the people, easy to defend and difficult to attack, officers and men who share the same hatred for the enemy, and clear rewards and punishments for military discipline. However, there are also obvious weaknesses, that is, there is a huge disparity between the number of defenders and the enemy's army, and the deployment of defensive equipment is insufficient. ”

"Specifically, the main hanging gate and the left and right hanging gates should be set up above the city gate; there should be special tunnel troops armed with bows and arrows to deal with the enemy's cave attack; in addition to weapons, all kinds of fortification tools should be prepared, such as iron hoes, axes, sickles, long cones, etc.; firewood, trees, and earth should be used to temporarily strengthen the city wall to make the city wall more solid; it is not enough to build only one outer gate outside the city gate, but two gates, one for the boudoir gate and the other for the Guo gate; in addition to arranging archers on the fence, it is also possible to bury the shooting machine to increase the attack range. ”

"Firewood and grass should be buried in the trenches to prevent the enemy from filling the trenches by fire; fire extinguishing tools must be prepared on the city walls, generally every ten paces there should be a large tank full of water, and flammable materials should be sealed with thick mud to prevent the enemy from attacking; the walls outside the city within 100 paces of the moat should be cleared, and the large and small trees should be cut down to prevent the enemy from taking materials on the spot; tall buildings should be built on all side roads and shortcuts to keep an eye on the enemy, and bamboo arrows should be inserted in the water to prevent the enemy from approaching. ”

"By the way, there is another thing that I have not heard the lieutenant general mention just now, that is, the fort on the city wall, such a fort should be set up every twenty paces to fire cannonballs at the enemy, this is a kind of city defense mechanism with great lethality, if there is such a thing, it will greatly improve the success rate of this battle to defend the city. ”

Because there has been no war for nearly a thousand years, and there is a serious shortage of vehicles, it is not possible to set up one every twenty steps, and one every hundred steps can only be done. ”

Hearing this, Shuwan frowned again and muttered to himself.

"Such a small number is definitely not enough to deter the enemy...... There are still days and two nights, I don't know if it's too late, no matter what, I can do whatever step I can. ”

Qiu Guangqi heard Shuwan's self-talk, and said in his heart that this girl didn't know how to make a borrowed car, so he hurriedly asked.

"Girl, but there is a magic method?"

I only heard that the book was late and threw back a question.

"I wonder how many mechanics in the army are still proficient in simple mecha skills?"

Qiu Guangqi turned his head sideways and whispered to the guards behind him.

"Go and ask He Liangping, the commander of the mecha battalion, to come over. ”

The guards quickly answered, and immediately left the room and went to the mecha battalion to ask for someone, and after a while, I saw a big man about two meters tall walking in and giving a military salute to Qiu Guangqi.

Qiu Guangqi nodded and asked.

"Ryohei, how many mechanics do you have who have mastered simple mechs?"

"There are only twenty-eight who are proficient, one hundred and twenty who are proficient, and twenty-five who are apprentices. ”

Qiu Qiguang set his eyes on Shuwan, who pondered for a while and spoke.

"In order to save as much material as possible, this time I only need to call in twenty-eight mechanics who have reached mastery, and from tonight onwards, I will work in pairs to make a batch of borrowed cars overnight, and I will teach them how to make a quick success, and I hope that a batch of borrowed cars can be urgently made before twelve o'clock tomorrow night. ”

Hearing this, Qiu Guangqi swept away his depressed look, and praised him excitedly.

"Okay, very good! Ryohei, from now on, all the personnel and materials of the mecha battalion will be freely deployed by this late girl, and you must cooperate with her work. ”

He Liangping read a lot of books with suspicious eyes, obviously very puzzled why the lieutenant general favored this female streamer so much, as a typical big man, he was ordered to obey a woman's orders, this is the first time, and he is obviously ten thousand uncomfortable with this situation. However, he was still very clear about the truth of the military order, and hurriedly agreed.

Qiu Guangqi then asked.

"The response to the cave attack mentioned by the girl just now is indeed the weakness of our army, mainly because our army lacks a cave surveyor who knows how to explore the location of the enemy's tunnel, I wonder if the girl is proficient in this way?"

Shuwan smiled slightly and replied.

"It is not easy to say that it is simple, but it is not difficult to say that it is difficult. As long as you follow the following steps, you will naturally know whether the enemy has started to attack and where the tunnel is located. The first step is to build a tall building in the castle to closely observe the enemy's situation, if the enemy is observed to build bunker walls, accumulate earth and rock, and the surrounding water shows signs of turbidity, it means that the enemy is digging tunnels, and it is necessary to dig trenches and tunnels in the direction of the enemy as soon as possible. ”

"In the second step, if it is not possible to determine the direction of the enemy's attack by means of observation, it is necessary to dig a well in the pass, and dig a well every five steps, which should be close to the base of the city wall. The depth of the well is about five feet in the high ground, and the water is three feet deep in the low place. Then he ordered the potter to burn the jar with a large belly and a small mouth, and put the mouth of the jar tightly with thin leather into the well, and sent a person with a keen sense of hearing to lie down on the mouth of the altar and listen to the sound from the ground, to find out exactly where the enemy's tunnel was, and then dig a tunnel to fight it. ”
