Liu Yujue asked: "So how does the teacher think the current city wall should be built?" ”

Guo Yixuan said: "Low and thick walls should be built, such walls are not only easy to erect all kinds of heavy weapons, but also difficult to break through by the enemy's siege artillery.

Giant stone throwing machines, ballistas, artillery, rams, excavation equipment for tunnel operations, ......, all kinds of attacking weapons are available, dazzling.

Timur's wanton expansion and invasion in Central Asia, West Asia, and Europe made a large number of scholars from all over the world flock to Samarkand, so Samarkand obtained military technology from Greece, Rome, Iran, India and even various places in China, and there were many engineers, architects, mathematicians, chemists, astronomers and ...... in his army, and the knowledge of these scholars was used in the manufacture of weapons to kill and destroy Xìng.

"This is a light cannon, this is a heavy cannon, oh, there is a medium rapid-fire gun, generally speaking, all kinds of cannons can only be fired five or six times a day, and this rapid-fire cannon has reached thirty shots a day without being scrapped under our continuous development and improvement!"

Guo Yixuan proudly introduced the terrifying murderous weapons to his beloved disciple: "Look, this is a field artillery, this is a siege artillery, and this mortar with a caliber of 850 mm and a range of 200 to 500 meters is also used to siege the city. Oh, by the way, you see, this is our latest siege cannon! ”

Guo Yixuan walked a few steps quickly and came to a huge, daunting super-giant stone shooter at first sight, Liu Yujue's first sight was not this super-large war cannon, but the shells piled up next to the war cannon. Those cannonballs are polished extremely round stone balls, and when he saw this cannonball, Liu Yujue gasped, and looked at it coldly, and the stone ball was afraid that it would weigh thousands of catties.

At this time, one catty is sixteen taels, that is, according to the algorithm of modern people, the weight of this stone ball is about 1,500 catties. It's too terrifying, if such a cannonball hits the city wall, ...... Liu Yujue suddenly thought of what Guo Yixuan said in the bathroom just now, no wonder he dared to boast that the taller the city, the easier it is to be destroyed.

Standing in front of this behemoth, Guo Yixuan could only reach the gun mount of the towering giant cannon, he stroked the gun mount and said: "This kind of cannon requires two hundred skilled gunners and sixty oxen to tow and use, and it can only fire a maximum of seven shells a day. But ......, what does it matter, hehe, such a cannon, just one is enough to open an irreparable gap in the strongest city walls, and let our valiant soldiers rush up the city! ”

Liu Yujue said in surprise: "How can such a huge cannon be transported? ”

Guo Yixuan said: "The further east you go, the more difficult it is to get enough materials to build these equipment, so you have to go here to build it." At the beginning of the war, the light siege equipment will be carried with the army, and the heavy equipment will be later, but it will not be delayed for too long, because these things can be disassembled, we have done tests, carrying this dismantled heavy siege equipment, an average of thirty miles a day. ”

Liu Yujue said in surprise: "Can it be so fast?" ”

Guo Yixuan said: "How about it, now you have a little confidence in our army to break through Jiayu Pass, right?" ”

Liu Yujue nodded again and again: "The teacher is right, with such a sophisticated weapon, Jiayuguan must be fine!" ”

Guo Yixuan laughed, patted him on the shoulder and said, "When the Great Khan invades Jiayu Pass and eliminates the Ming Dynasty, you don't have to hide in Tibet!" The Great Khan can not only avenge this annihilation for you, but also a talent like you will reuse you as a magistrate in Daming. ”

He looked leisurely to the east, and the sunset reflected in the sand made the shallow wrinkles on his face shine as if they were made of brass.

After staring for a long time, Guo Yixuan said softly: "People say that the sunset is the end of the world, and the end of the world is not home." has hated Bishan to block, and Bishan is still covered by twilight clouds. The old man is already half of the earth, I really want to go back to Dadu, I really want to go back to my hometown......"

For a moment, there were tears in his eyes......

※※※※※※※※※※※※※※※※※※※※※※※※※

"Okay, it's not too late, Yuluo, you can go back and rest."

When Liu Yujue sent Guo Yixuan back to his residence, Guo Yixuan's mood had calmed down.

Guo Yixuan also has students in Samarkand, but none of those students are as respectful as Liu Yujue, who treats Guo Yixuan in accordance with China's thousand-year-old way of respecting teachers. Therefore, Guo Yixuan likes and appreciates this disciple more and more.

When he returned to his sleeping tent, Guo Yixuan and Yan Yue asked Liu Yujue to go back to rest.

Liu Yujue has always wanted to ask for more useful information from Guo Yixuan's mouth, but he can only knock on the side, analyze and understand from the information he has mastered bits and pieces, and today it is rare to see Guo Yixuan feel homesick, and his mind is a little depressed, thinking that if he can persuade him to drink a few glasses of wine, as soon as people say that they are drunk, their mouths will be gone, or they can ask more things.

So, Liu Yujue said respectfully: "Mr. is depressed, otherwise...... How many drinks will the disciple have with the teacher? Drink some wine, and the gentleman may be in a better mood. ”

"It's rare for you to have a piece of filial piety!"

Guo Yixuan's god became more and more relaxed, and said with emotion: "When it comes to respecting teachers, I have to count my country of Chinese etiquette." Your filial piety has been received for the teacher's heart. However, this wine is free! ”

Liu Yujue was still waiting to say more, Guo Yixuan shook his head and said, "Yuluo, you don't know anything." You don't see that this place is noisy and chaotic, like a city, but after all, this is a military camp, and you usually walk around here, you can see everything, but is there a tavern, is there it? Hehe, the army has its own law in the army, and this wine cannot be drunk. ”

Guo Yixuan smiled and said: "Unless there is a major festival, or the Great Khan has won a great victory, and there is something very happy, drinking will be allowed.

You see that there is usually a lot of discipline in this barracks, right? But every time at that time, after a night of drinking, there is a mess everywhere, which is more chaotic and lively than in the market, but the opportunity is rare, otherwise, if you accept such a proud disciple as you, don't you eat a banquet for your teacher? Haha......"

Guo Yixuan smiled and waved his hand: "Go back and rest, I'm going to sleep for the teacher!" ”

"Yes!"

Liu Yujue was helpless, so he had to bow down and watch Guo Yixuan enter the tent, and then he left.

On that day, Xia Xun asked him to plan and worship under Guo Yixuan's door, originally to have the opportunity to get close to Timur. Who knew that the clouds and mountains blown by Guo Yixuan in front of him seemed to have great ability, but when he entered the barracks, he realized that it was difficult for Guo Yixuan to see Timur, let alone his little apprentice.

Today, although Liu Yujue did not have more clues that could be mixed into the barracks, he saw with his own eyes the power of those siege weapons, although there are such sharp weapons, they may not be as devastating and all-encompassing as Guo Yixuan boasted, but its sharpness is indeed far beyond the previous Ming Dynasty's assessment of the siege weapons and tactics of the Timurid Empire.

These things should be the weapons designed and manufactured by the Timurid Empire by gathering all kinds of scholars and skilled craftsmen to specifically target the Oriental city defense of the Ming Dynasty, which is a very important piece of information, and he needs to tell Xia Xun immediately. After leaving Guo Yixuan's residence, Liu Yujue hurried outside the barracks!

P: Ask for recommendation tickets, ask for monthly passes!。
