Zhuge Liang wanted to be a guest for Xun, but Xun said that the number of customers was enough, and he didn't want to add more. When Zhuge Liang heard this, he couldn't help but blush, and said in his heart, Am I wrong this time?

When he was very embarrassed and didn't know what to do, he heard Shi Xun slowly say again: "Ranwu wants to start teaching apprentices recently...... Zhuge Liang reacted quickly, and quickly fell to the ground: "No, I am willing to learn from Mr." ”

Yeshun had already had the idea of accepting a few students, but his research on the scriptures was not thorough enough...... To be more precise, the system of "Shi's Apocrypha" is not complete enough, so I only dare to go to Taixue or Hedong County School to take classes, and I dare not be like Zheng Xuan, and accept apprentices seriously. But today, Zhuge Liang came to vote, and a flash of inspiration suddenly flashed in his mind, and he said in his heart that I might as well accept "Wolong" as an apprentice - the relationship between teachers and students is much closer than the relationship between host and guest!

As for what he can teach Zhuge Liang...... Whatever, take it first.

Zhuge Liang knelt down and kowtowed, but Shi Xun hurriedly supported him with both hands and said to him: "There is no etiquette in the army, the first master and apprentice are the first, and it is not too late to salute after defeating and returning to Xu." "Let's settle down first, and then open the incense hall when we go back...... Ah no, let's officially hold the ceremony of accepting the apprentices.

Zhuge Liang kowtowed three times, and then stood up in the midst of Shi Xun's weak support. Yeshun dragged him into the tent, sat down on the seat, asked a few casual questions, and suddenly thought of one thing - "Has Kong Mingke ever married a wife?" Zhuge Liang replied honestly: "The daughter of Huang Chengyan of Xiangyang has been hired, and it is agreed that he will marry after three years of mourning." "It's Xun Xin who said sure enough, you pretty young man still wants to marry that black-faced and yellow-haired girl after all...... I don't know who Zhuge Zhan looks like later, is it my father's genes that won, or my mother's genes that won?

He just asked casually, he really didn't have any interest in the little girl of the Huang family. Zhuge Liang decided on this family affair because he liked it or because he was in love with the Jingzhou clan, and it had nothing to do with him, and he didn't believe that Huang Yueying (if it was really called this name) was a Ming family that was more clever than Zhuge Liang in folklore, at most it was just a virtuous helper behind a successful man.

As the master and apprentice chatted, the conversation naturally turned to the current war. It's Xun Zhuge Liang, you came just in time, you are going to attack for the first time tomorrow, you can open your eyes. Zhuge Liang was strange: "The disciple heard that the king master only started the camp today, and he will attack tomorrow, I don't know how to prepare the equipment?" "It's Xun Xin who said that it's really not a rotten Confucian who reads dead books—this kind of knowledge, which can't be learned from ordinary books—that a fledgling has such insight. That's amazing, but: "I have my own clever plan, Kong Ming and wait and see, hahahaha~~"

The two kept talking about the moon and the middle of the sky, which seemed quite speculative on the surface. According to the character of Zhuge Liang recorded in the history books, Shi Xun is loyal, diligent, cautious, thoughtful, ambitious, and self-proclaimed justice...... Leads the conversation almost perfectly. He knew that this kind of strongman bowed down when he saw him. A big factor is his own status and fame, not his own real Su zhì to convince him, and it is difficult to really subdue him without time and carelessness.

The next day, he got up at dawn, and he took Zhuge Liang to meet his disciples Guo Huai, Dong Meng, Qin Yi and others, Guo Huai and Dong Meng heard that Zhuge Liang had worshiped under the Xun Sect as a disciple. can't help but reveal a hint of envy. Shi Xun weighed it in his heart, Dong Meng forgot it, and when he returned to Xudu and officially held the apprenticeship ceremony, he simply counted Guo Boji as well, the little guy deserves his own attention.

Then he went to see Luo Yuanba, and saw that the thirty stone-throwing carts had indeed been completely completed, each of which was surrounded by twenty trained soldiers. Just waiting for the order, he pushed out the walled gate and went to attack Yecheng. When Zhuge Liang saw these stone-throwing carts, he couldn't help but be amazed, Shi Xun simply took care of Guo Huai: "Boji and Kong Nian's teeth are similar, but they can be more close, and the matter of the cart." It can be explained in detail. ”

He himself went to the Great Tent to meet Cao Cao. At this time, the drums in the army sounded, and the generals gathered before entering the tent door. Cao Cao asked, "Are you ready?" Shi Xun bowed and replied: "All are ready, and the projectiles are sufficient, waiting for the lord's order, you can advance and defeat the enemy's base." ”

Cao Cao said okay, today in the east of the city to try the attack, looking left and right, pointing to Cao Hong and said: "Zilian first." Cao Hong was overjoyed and promised to do so.

The direction of the main attack was set to the east of Yecheng in order to widen the distance from the polluted city where Yuan Shao had stronghold. It was the commander who hurriedly ran back to the place where the stone-throwing cart was, beckoned Guo Huai to come over, and informed him of the news. Guo Huai said: "Huai went out of the camp yesterday to investigate, the south of the city, the east of the city, have been positioned, the lord do not worry." "Yes Xun was afraid that Guo Huai had checked the south of the city, not as good as the east of the city, so he was relieved when he heard this.

At that moment, he commanded the people to push the stone-throwing carts out of the camp and go straight to the east of the city—each of which was followed by five horse-drawn carts, loaded with various types of ammunition, and guarded by 400 troops and more than 1,000 foot soldiers. Not far away, Cao Hong also led the troops over, and immediately asked Shi Xun: "I don't know if it is possible to set up parking before noon?" Shi Xun smiled: "Do it immediately, Zilian can wait a while." ”

It turned out that Guo Huai had surveyed the terrain in advance and visually measured the distance, and had already made a mark in a position suitable for the placement of the rock-throwing truck. I think it was Xun who saw the stone throwing cart for the first time in the workshop, and saw that Xie Zheng first took his eyes for a long time, and then rowed on the ground for a long time, and finally set it up, it took a lot of time, and in the end it was not accurate, and he looked at the old and reliable. It's a pity that he is not a student of science, not only is he completely unable to calculate mechanics and parabolas, but even the most ordinary arithmetic knowledge is basically returned to the elementary school teacher, and he is in a hurry but can't help.

Thinking about it again, I won't always have anyone, although the mathematics of these years and months is not up to it, but it shouldn't be too difficult to find a few top people to come out and study the ballistics problem - anyway, the accuracy of the catapult is there, even if the calculation is clear, the error rate is still not small, and it is a victory to be able to calculate it more accurately than Xie Zheng.

So, where to find a math strongman? Fortunately, there is one in front of him, Zheng Xuan and Zheng Kangcheng are well-known top figures in these years, it is said that he once helped Ma Rong calculate the problem of Hun Tian - what exactly Hun Tian said, Shi Xun naturally does not understand, but I also know that it will not be pure divination and witchcraft, but there must be mathematics mixed in. So Shi Xun took the initiative to come to the door, and took the opportunity to beg Zheng Xuan to allocate some supplies to the water master, and cautiously asked for advice.

Zheng Xuan was quite interested in this question, so he immediately took out the calculation chip and put it in front of Shi Xun. Shihoon was full of admiration...... I didn't understand it, so I turned my head and pushed Guo Huai out. Guo Huai studied with Zheng Xuan for several days. Come back and tell Shixun, this is a problem...... Looking simple, it is complicated to calculate, and Mr. Zheng has just touched the door - Yes Xun does not know, this related trigonometric problem was officially introduced to China in the Ming Dynasty, and the Chinese have not studied it before. But the fragmentation is completely fragmented.

Shi Xun pondered for a while, and said that there is no problem, just touch the door, I don't believe that Mr. Zheng is not a thank Daoist. Let's calculate and test with the assistance, line up the stone throwing trucks, and aim at a target to hit back and forth. After finishing according to different distances, with different counterweights, list a table, and then make a mark on the stone throwing car, sure that the accuracy can be greatly improved.

So last night, Guo Huai went out of the camp to survey the terrain, and by the way, he visually measured the distance. The parameters were calculated. When it was time for the official attack, thirty stone-throwing carts were lined up, Guo Huai dipped a little saliva, raised his fingers, roughly measured the wind, opened the table, and immediately reported a series of numbers.

Zhuge Liang saw it next to him, and his eyes couldn't help but shine. Yes Hoon saw it from the side. The heart said that Kong Ming really has the potential to be a Ming family, it seems that this thing is very appetizing to him.

At this time, Cao Cao also arrived, of course, he would not be on the front line in person, but took his twelve-year-old second son Cao Pi to an arrow oar a hundred steps away behind him. Cao Cao went out this time without his eldest son Cao Ang. And with Cao Pi, Cao Ang was appointed as the general of the five officials, and stayed behind in Xu Du - Shi Xun understood, this was equivalent to semi-formally determining Cao Ang's heir status.

As soon as you see it, you can continue. It was Xun who sent Dong Meng to report to Cao Cao. After a short time, he heard the drumming behind him like a shocking sound, and Shi Xun immediately waved the order: "Shoot!" ”

Prior to this, according to Guo Huai's calculations, the soldiers had already prepared the stone bullets and counterweights, and with a wave of the small flag, the quick knife cut down, cut the leather rope that bound the long end of the throwing rod, and the short rod counterweight flew down, so thirty fifty-pound stone bullets drew an arc and flew straight to the city.

It's Xun who put his hand on the canopy, and look at it, hey, don't say it, Guo Huai's calculation is quite accurate, if this is the city wall, it is estimated that at least half of it can be hit. However, the target of the problem is not the city wall, but the sheep and horse wall on the inside of the moat, or the sheep and horse wall. In a big city like Yecheng, it is impossible to defend the city wall alone, but first have to build a sheep and horse wall to defend outside the city, and strive to greatly kill and damage the enemy who is attacking the city. The trial did set up a number of sheep and horse walls, which basically blocked the road for Cao Jun to cross the trench.

The sheep and horse wall is only one person high, and the target is much smaller than the city wall, so this round of throwing stones, although there are not many left and right deviations, but it is either near or far, or it falls into the moat, stirring up a high splash, or directly passing over the wall, almost smashing on the city wall, and finally only four of them.

But this is enough, the sheep and horse walls are all temporary earth fortress cities, rammed not strong, a stone bullet hit, it is a big gap, as for the Yuan soldiers behind the gap, it is estimated that even the corpse is broken. Cao Hong's subordinates were guarding the stone-throwing trucks, and they all raised their arms and cheered when they saw this. Shi Xun couldn't help but smile on his lips, and simply handed the command flag in his hand to Guo Huai, and encouraged: "Very good, and those who vote for four more wheels." ”

Guo Huai bowed down to take the small flag, measured the wind again, adjusted some parameters, and popped up four consecutive rounds of stones. Almost every round has four or five stone bullets, and the five rounds of one hundred and fifty stone bullets swept by, and a section of sheep and horse wall as long as 20 zhang on the south side of the east gate of Yecheng was almost smashed like a wheat cake that had been gnawed by a dog, and basically did not play any defensive role.

Seeing that a large group of Yuan soldiers were forced to withdraw from behind the sheep and horse walls, some of them went around to the city gate, and the city gate opened a small crack to let them in, and some of them directly grabbed the ropes laid down on the city and climbed up with their hands and feet. Cao Hong was overjoyed when he saw this, so he gave the order: "Negative soil, fill in the trench!" But he was stopped by Shixun. Yes Xun said slowly, there is still one thing that must be broken so as not to suffer unnecessary casualties.

He set his sights on the small wooden houses jutting out of the walls.

ps: How about it, Zhuge Liang has also arrived, this time the big guy is satisfied. From now on, the protagonist really wants to be left Zhuge , right Sima, and Lu Su in the middle......
