Zhao Xingde had a headache because he didn't know how to build a city and got up out of thin air, but it had the advantage of avoiding the constraints of the previous generation's law, so he had to start a new stove and focus on giving full play to the power of artillery. The sound of the piano is melodious, and gradually it is deaf.

"For the army that fights in formation, it always focuses on frontal attack and defense, and the blow from the flank is always more troublesome than the front," Zhao Xingde scratched his head and muttered, "When building a city, you should do the opposite, emphasizing flank firepower, yes, this is the second principle, and it is important to give full play to the flank firepower." After thinking about it for a long time, he found another important principle, which he quickly wrote down on paper. When I was satisfied, the sound of the piano in my ears seemed to be less annoying.

In the middle of the night, the black magpie occasionally flies, the lights in Zhao Xingde's tent are always on, and in the dead of night, there is a low voice of self-talk from time to time. "The third principle is that the important gun position should be at the back, and the thoroughness of the protection should coincide with the importance of the gun position. ......""The fourth principle should be the position with the highest defensive efficiency and the most powerful weapon. Outnumbered, firepower in exchange for troops. The troops that have been saved, in the other sections of the city wall, should be overwhelmed by the outnumbered...... It is not necessary to form a positional encirclement, but to form a cross coverage of firepower. "....... "It's not easy to take into account all the principles, his grandmother's, it's too difficult to get a perfect city......" "Hmm, the wall where the gun emplacement is located and the fire defense wall are best at right angles, and the gunner can aim and fire easily......"

When he was about to go to sleep, Zhao Xingde suddenly remembered that the noisy qin song just now seemed to be "Guangling San", which was still Chao Buzhi telling him, "Really, this song should have been lost a long time ago." With this vague thought of his previous life, he fell into a deep sleep.

He may not know it yet, but when he comes to this world, he has a great sense of insecurity. Leaving the world and independent, it may just be a description for others, but for Zhao Xingde, who is reincarnated, it is his real situation. Although he was considered a good young man in his previous life, he may still have a lot of laziness and tiredness, and he has a passable temperament, but in this era, he is like walking on thin ice everywhere, and he is afraid that he will not do well enough to do everything, all because of this indescribable feeling of wandering. So far, Zhao Xingde's own origin has only been vaguely mentioned to Li Ruoxue. The construction of an impregnable city, to a certain extent, suited his certain state of mind, and he was unconsciously addicted to it, not just to fulfill his promise to the Han army.

......

"Captain Zhao, it's time to go."

"Hmm."

"Captain Zhao, eat some dry food, I said earlier, take a breath, avoid the most poisonous sun, and continue on your way."

"Okay."

"Mr. Zhao, the Lord of the Han League shot a deer and specially sent the barbecue, Chiliang porridge."

"Oh."

......

It was as if he had returned to his previous life, whether on the march or camping, the shape of the city came to his mind day and night. One day, two days...... Ten days, from scratch, from various principles, to the general pattern, to the implementation of the details, to the assumption that he is the besieging party with artillery and superior forces, constantly perfecting and improving, finally, the day before parting ways with the Han army, Zhao Xingde handed over a strange-looking city pattern to Wang Xuansu.

"Well, probably, maybe, that's ......." Facing Wang Xuansu's eyes of both doubt and shock, Zhao Xingde was very uneasy, and explained incoherently. Because he was completely immersed in the city, he hadn't spoken in full for about ten days, and now his tongue was much more clumsy.

Wang Xuansu stared at the strange pattern in his eyes, is this a city, even a simple walled fort cannot be built like this, it is not round and square, inexplicable shape, the trench is too wide, the underground passage, and the barracks are actually close behind the city wall. He forcibly suppressed the suspicion in his chest, and asked in the most peaceful tone possible, "Mr. Zhao, didn't you take the wrong pattern?" ”

Zhao Xingde was stunned for a moment, and smiled honestly: "No, hehe, how could it be." ”

Wang Xuansu was silent, and after being sure that Zhao Xingde was not joking, Rao was quite a city like him, and he also felt angry from his heart. Everyone expresses their anger in a different way, if it is Brother Zhang, maybe, he will block a few words in a weird way, Gao Bolong will ruthlessly tear the pattern into pieces and throw it on Zhao Xingde's face, Xu Detai may want to break off friendship with Zhao Xingde, and Wang Xuansu called other Han army generals, came to Han Ningshuang, and spread out the messy Nanshan city pattern painted by Zhao Xingde.

"This is the city map that Mr. Zhao drew for us." Wang Xuansu said lightly, with no joy or anger on his face. The so-called facts speak louder than words, and this is probably what he is doing now. Han Ningshuang and several other Han generals came up, and they were a little surprised at first, but immediately, Han Ningshuang's forehead wrinkled into a Sichuan character. After a while, Brother Zhang praised and said, "Oh, this guy is tortuous, is he repairing the garden?" Xu Detai sighed, Gao Bolong's face showed anger, and he said in a deep voice: "Mr. Zhao, what is going on with this pattern?" ”

Soldiers can be killed but not humiliated, isn't this clearly underestimating the Han army? In all fairness, asking Zhao De to draw such a crucial city pattern is in itself a great trust and value. And since Zhao De agreed to this, he should do it seriously, instead of dealing with it like this jokingly. Most of the cities in the world are square, occasionally with special shapes, just to take advantage of the momentum of mountains and rivers, and the appearance of this city painted by Zhao Xingde, if it is really built, I am afraid that even the Khitan people will be laughed at.

"Mr. Zhao, what's going on with this pattern?" Han Ningshuang asked, with a thick puzzle, and her tone was much more relaxed than Gao Bolong's.

"This, probably, that's the case......" After thinking for a long time, Zhao Xingde still decided to speak with facts, he stood in front of the drawings, sorted out his thoughts, and had a simple smile.

"Let's take a look at this place first, let's call it the horse face, because the horse face is very large, and if the enemy army does not attack the horse face and goes straight to the city wall, it will be hit by the cannons and bows and arrows on the three walls. Moreover, the city wall connecting the horse face is very short, and the space under the city wall is too narrow, and the army that attacks the city is crowded here, which is almost like waiting in line to die. So if the enemy army is not too stupid, it will definitely attack the horse face first. That is, these two walls. Hmm, is there a problem? As he spoke, he raised his head and looked at the crowd, a habit he had developed a long time ago.

The generals of the Han army looked at each other speechlessly, and after Gao Bolong "snorted", Xu Detai kindly reminded: "Mr. Zhao, shouldn't the horse face be square?" "The city painted by Zhao De, the horse face that should be boxy has a big horn out of thin air, which is really uncomfortable to watch.

"That's right," Zhao Xingde nodded kindly, and took out a few small samples of horse faces drawn during the conception process, "To compare the shapes of various horse faces, only this kind of sharp angle can ensure that there are no dead ends in side shots." He had already sketched the general line of fire with a pencil, and with a little command, the generals of the Han army could roughly understand what he was described.

After looking at these carefully depicted graphic samples, the mood of the generals of the Han army stabilized a little, at least Zhao Xingde was not doing it indiscriminately. "Side shots?" Wang Xuansu was puzzled, "Aren't they all firing arrows and cannons from the city?" ”

"Because the head of the city is shot downward, there is a big dead angle, so it is better to shoot from the side," Zhao Xingde explained, "The flank of the enemy army in formation is always weaker than the front, and it is easier to cause the enemy to collapse when hitting the flank," he smiled a little embarrassedly, "In the future, if the enemy is attached to the siege of the city, the artillery bombardment from the front of the city can only penetrate a thin front, and maybe only a few people can be killed." However, if you bombard the wall from the side along the straight line outside the city wall, you think about it, the effect may be different, right? With sincerity on his face, Zhao Xingde drew with his hands in the air, trying his best to depict the enemy army attacking the city under the straight line of the city wall, and at this time, a cannonball from the flank was also fired along the outer edge of the city wall.

“...... Such an angle of fire allows the shells to pass through as many enemy troops as possible, and you see, there are wide trenches under the walls, which is perfect if the shells fired from the side form a bouncing effect in the trenches. The two long gun emplacements on the front of the "......" defense of the enemy platform are the most important, and according to the principle of the most important gun emplacements being the most tightly protected, they are arranged exactly on the short side of the enemy platform at the rear. This is not arranged by me, this is the will of heaven, it is really a coincidence, and the front wall of the enemy platform has a right-angle relationship This city wall is located right behind the side of the enemy platform, hey, hey, the magic hand is even there," Zhao Xingde smiled modestly, "If the enemy wants to kill him, he must first cross the low wall, and then the trench, in these places they are all hit by crossing, and finally they come to the place where the cross-fire is most intensive, and every enemy army under the city must suffer intensive shooting on three sides, so as to attack our most important artillery position, And even if we climb the wall, we have the advantage of numbers......"

With his rambling introduction, the faces of the generals of the Han army slowly became solemn, what kind of city is this, it is simply a trap to kill, when Zhao Xingde finished speaking, he spread his hands and said sincerely: "That's it, although it is ugly, it is better than the original city." After all, the city is not built to invite guests to dinner. Looking at his honest and sincere smile, several people felt a chill rise from the bottom of their hearts.

After being silent for a long time, Han Ningshuang raised his gaze from the pattern and said in a deep voice: "Mr. Zhao's counselor is grateful for his planning, and the Han army is grateful. There was a shock in her words that followed the sincerity. Zhao Xingde arched his hand and smiled: "It's easy to say, it's not enough to worry about." All the generals of the Han army remained silent, no one knew how many lives could be saved by the pattern of this city, from the perspective of great grace and gratitude, everyone was not good to say anything, after all, Zhao De was not a member of the Han army. Rao was shocked, and no one could go over and pat him on the shoulder and praise, "Good brother, you really have you." ”

After Zhao Xingde said goodbye, the generals of the Han army continued to discuss around the city pattern, and Zhao Xingde introduced it in a hurry, but he roughly explained the meaning of the various patterns, and also demonstrated the use of various arrangements in the offensive and defensive situations. At this time, the generals of the Han Army discovered some wonderful things that Zhao Xingde did not have time to introduce. Zhang Liuge sighed: "This Mr. Zhao is really a strange person. He thought about it for a long time, and felt that only the word "strange person" was the most appropriate.

Han Ningshuang remembered the rumors of the Science Society, and said with a smile: "It's not strange that a person like him has this kind of ability hidden. This sentence has no beginning or end, and it seems very familiar, and everyone is puzzled, but they don't dare to ask more.
