The King of Quick Mouth said excitedly: "Don't be tired, not tired, it's an honor for the old man to be able to tell His Highness, if His Highness hasn't enjoyed it, the little old man will say a few more paragraphs to His Highness." ”

Li Shimin said with a smile: "You have been tired for a long time, it is not too late to talk about it next time, there is something I want to ask my uncle to solve my doubts today." As he spoke, he beckoned Cheng Chumo and Yu Chi Baolin to his side and said to the King of Fast Mouth: "These two children are the sons of the king's generals, and the king was originally going to take advantage of this time to go to Xiaoyi's place to relax, but these two boys secretly followed, saying that they wanted to be heroes and enlist in the army." When I asked the reason, I realized that it was after listening to "The Legend of the Condor Heroes" that I had the idea of joining the army. This king wants to ask my father-in-law, is this book really so charming? ”

The King of Fast Mouths looked at literature and art, and said with a smile: "Your Highness doesn't know, Xiao Lao'er met Xiaoyi because of a blessing in disguise, this child listened to the book review first, and the old man told him a few paragraphs of our storyteller's methods, but Xiaoyi was very dissatisfied, so he taught "Shooting the Condor" to the old man. The old man was originally going to wait for Xiaoyi to come back and then say goodbye in Crooked Willow Village, but Xiaoyi went to Chang'an for a long time and didn't return, so the old man had to make someone return to Meixian with a message, I didn't expect "Shooting the Condor" to be so attractive, there were only a few people when I first started speaking, all of them were regular visitors or idle rangers. When the second lecture started, there were more people. By the time the whole book was finished, there were too many people to squeeze in. As the saying goes, there are blessings and hardships, so the old man taught this book to a few peers. So that they can have a good life too. ”

Then he arched his hand to the literature and art and said: "The old Han Dynasty colleagues thank Xiaoyi for their great kindness!" ”

Wenyi smiled and saluted: "Grandpa Wang is polite, Buddhism has clouds: giving people roses has a lingering fragrance, and you don't have to take it to heart for small things." It's just that this one "Shooting the Condor" is boring if it talks too much. How about I tell you a few more books? ”

The King of Fast Mouths stood up and said with burning eyes: "Xiaoyi, is this true?" This kind of kindness of the old man is broken and his bones are broken! After speaking, he was about to kneel down to Wenyi, but Wenyi hurriedly stopped him, and pulled up the old man's body and said: "The kid is young, he doesn't dare to be a big gift to Grandpa Wang, if you want to be so polite again, then this matter will be stopped." ”

Old man Wang hurriedly stood up, not daring to say anything more about kindness, for fear that literature and art would not teach him new books.

Wenyi returned to his seat and said: "Grandpa Wang, I have prepared three books, one is called "The Condor Heroes", which starts with "Condor Shooting", which is about how a wicked person becomes a hero admired by the world; One is called "Romance of the Three Kingdoms", which mainly tells the story of the Three Kingdoms period; A book called "Romance of the Sui and Tang Dynasties" is about the current heroes and heroes from all walks of life, but only half of this book is undecided, and there are still places that need to be added. ”

Old man Wang was busy nodding his head to look at the posture, and he couldn't wait to talk about literature and art to him now. Wenyi smiled: "Grandpa Wang, I am all improvised, I can't tell you from time to time, it's better to let your grandson go back to Crooked Willow Village with me, the kid can write a book while teaching Erxuan to recognize words, although the kid has not learned the Four Books and Five Classics since he was a child, but it is no problem to teach Erxuan to read and write." ”

Old man Wang was overjoyed, and hurriedly called Erxuan from behind, and stuffed it directly to Wenyi's side, depending on the situation, Erxuan will follow Wenyi from now on. Wenyi asked Zhang Mazi about it again. Old man Wang said with a smile: "Zhang Mazi waited for you for half a month, seeing that you didn't come back, I heard that His Royal Highness the King of Qin broke Wang Shichong, and he thought about going into battle to kill the enemy and make a name for himself all day long, so he asked the old man to give you a message, he went to Chang'an, and planned to join His Highness to fight in all directions." ”

Literature and art smiled bitterly, do you still need to sign up for Li Shimin? Say no to him and you're done. He likes Zhang Mazi's honesty, but it is difficult for such a person to go to the battlefield and want to be confined all over. said to Li Shimin: "Your Highness, Zhang Mazi is a simple person and a friend of the boy. It is difficult for him to protect himself in the army, and the kid wants to ask His Highness to help take care of one or two. ”

Li Shimin nodded and said: "No problem, I will let people look for it, if it really arrives in the army, this king will arrange him to be in the king's personal guard, and I will let people take care of it." ”

After chatting for a while, they dispersed. Back in Crooked Willow Village, Wenyi invited Li Shimin to visit "Hope".

They haven't come back for a few months, and Wen Yi and they are all about to turn "Hope" into a bandit village. Two bear skins hung there at the door, and the head was retained, looking hideous and vicious, with a corner tower erected at each of the left and right corners, two Wenliu machine guns were mounted in front, and two sentries stood behind, and when they saw literature and art, they shouted happily: "The young master is back!" Brothers, hurry out to greet them! ”

I heard a commotion inside, the door opened, and dozens of men were used, wearing cotton coats, all of them looking energetic. When he saw Wenyi, he hurriedly shouted: "I've seen the young master!" ”

Wenyi bowed and said: "His Royal Highness the King of Qin has come to see you, hurry up and come to pay respects." With that, he stood behind Li Shimin. These people were originally Li Shimin's personal guards, so Li Shimin was very familiar with them, and he walked into the "hope" after meeting the ceremony at will, and the eyes were the tall steel-making furnace, which was still burning with a raging fire, and all kinds of strange materials were neatly placed on the shelves, and each room was only separated by a cement wall, without a door wall, and the outer walls were equipped with glass, which was wide and bright. The floor was also poured with cement and coated with thick paint, making it smooth and level.

Li Shimin was curious: "Xiaoyi, what material do you use to make the walls?" I don't think I've seen it. ”

Wenyi smiled and said: "Your Highness, this is cement, and the whole "hope" is poured out of cement, steel bars, and stones, which is extremely strong and can resist the fire of Wen Liu's machine gun, and even the artillery can't penetrate it. The floor is also paved with cement, which can withstand more weight. ”

Li Shimin said happily: "Cement is willing to produce energy? If all the cities of the Tang Dynasty were poured with cement, wouldn't the city walls be unbreakable? ”

Wen Yi said with a smile: "Your Highness, cement can indeed be mass-produced, but the kid is not recommended to take it out and use it now, in case the enemy also knows the formula of cement, it will cause a great obstacle to His Highness's conquest, and it is not too late to promote cement after clearing the traitors." ”

Li Shimin was helpless, he also knew that as soon as cement appeared, it would be like papermaking and would not be able to hold it at all, and it would only cheapen the opponent.

Wenyi said: "Your Highness, I have a lot of new things here, let's take a look." After speaking, Wen Twenty asked, "Have you made what I gave you?" ”

Wen Twenty said happily: "Young Master, I have already made it, and I have tested it, and the power is amazing, I will take it to you now." With that, he ran into a room, and in a moment he came with a long, thick round pipe. Literature and art were happy when they saw it, a good thing, so he explained to Li Shimin: "Your Highness, this is a single bazooka, which can be operated by a single person, and can bombard the target from a distance of one mile." If the shell falls into the crowd, there will be no live opening within 20 steps, and there will be heavy casualties within 30 steps. If the city walls are bombarded, all the cities at present will not be able to withstand twenty rounds of artillery bombardment, and the walls will be reduced to powder. ”

Li Shimin's eyes lit up, so he took it over and took a closer look, the black barrel has a grip underneath, the design is simple, the back of the barrel is not blocked, it can be opened, but it can't be seen from the left and right.

Wenyi smiled: "Twenty, you did it, what did you name it?" ”

Wen Twenty replied: "Young master, I originally wanted to call it Wen Twenty Cannons, but no matter how I heard it, it didn't have momentum, so I called it the Sky Cannon." ”

Wenyi smiled: "Good name, hurry up and demonstrate the power of the Sky Bombardment Cannon to His Highness." ”

Wen Twenty smiled bitterly and said: "Young master, we are surrounded by trees, it's not easy to demonstrate, why don't you wait for us to go out and try again?" ”

Wenyi thought about it and felt that it was inconvenient in this vicinity, so he nodded and said, "You go and prepare a few shells, and I will call you later." ”

Wen Twenty nodded in agreement, turned around and went back to his workshop. Wenyi shouted again: "Wen San, have you done what your group has done?" ”

Wen San smiled: "It's been done, but no one dares to use it, and I haven't tried it yet, so I'm waiting for you to come back and test it." ”

Wenyi nodded and said, "Okay, you go and fill up the gas first, and His Royal Highness and I will go over in a while, if you succeed, you will be credited!" ”

Then he took Li Shimin to see the Gatling and AK rifles being developed, but these two are not low in terms of materials and technical requirements, Wen Liu They have not succeeded, but they also made Li Shimin ecstatic, and began to imagine that he was holding a sword in one hand and an AK in the other, riding a war horse to kill the enemy, and no one dared to stop the scene.

Wen Shi's ** has been studied, but he just complained to Wenyi, he originally remembered the name of Bang Tianlei, but Wen Twenty's grandson used it first, and he could only use the name of ***. Wenyi laughed and scolded a few words, and asked him to hurry over and prepare to test the power. After some inspection, everyone has grown a lot, and all the tasks assigned by literature and art can be completed perfectly. Literature and art are very satisfied with them, and specially allow them a month's vacation, so that they can go to Chang'an to have a good time during the New Year.

Wenyi took the somewhat sluggish Li Shimin to the backyard, and saw an elliptical machine with a long tail and a huge fan blade on its head, Li Shimin couldn't help asking: "Xiaoyi, what is this?" ”

Wenyi said very proudly: "Your Highness, this is the kid's greatest achievement in recent years: helicopter!" It can take people to heaven. ”

Li Shimin's body shook, he was a little unsteady on his feet, and stammered in a trembling voice: "Can you go to heaven?" Then what are you waiting for, hurry up and go up with this king, this king wants to go to the sky to see if there are any immortals. After saying that, I couldn't wait to get ready to go up. Wenyi hurriedly grabbed him and said: "Your Highness, don't worry, the helicopter hasn't been tested yet, in case of failure, it will be troublesome, I'll go to the test flight in a while, if it's okay, the kid will definitely take you to the sky." ”

Li Shimin calmed down his excitement and said, "Okay, Xiaoyi, you hurry up, this king is already impatient." ”

Wenyi called Wen San and asked him and himself to do another inspection of the helicopter to make sure that it would not malfunction. This helicopter is the simplest single-propeller structure, the entire body is composed of planks and steel, the fuselage is wrapped in cowhide, and the monocoque tail boom. The cabin can accommodate 1 driver and 3 passengers. Four-wheeled landing gear. The power source is a newly developed star-shaped engine, which is not very powerful, but it can still be used in small helicopters. The rotor blades with a steel-wood hybrid structure have a short lifespan of about 600 flight hours. The blade airfoil is symmetrical and the tip of the blade is rectangular. There is no navigation, just a rough altitude gauge and compass. The maximum flight speed is about 200 km/h, the vibration level is about 0.25g, the noise level is about 110 decibels, and the ride comfort is very poor. But being the first helicopter is enough to make literature and art proud.
