Du He strode into the ordnance superintendent, and the ordnance superintendent was Zheng Ang, and when he saw him coming, his face turned white, and he turned around and ran away in fright.

Du He's eyes were quick, and he caught Zheng Ang first: "Zheng Jianzheng, where to go!" ”

Zheng Ang had a bitter face and begged: "My little ancestor, you can spare me, all the capable people under my command have been dug up by you, and you will come back!" ”

The Ordnance Supervisor is also an institution that manufactures and researches weapons and weapons, but compared with the Academy of Science and Technology in charge of Du He, the Ordnance Supervisor is like a posterity. Although it existed more than ten years earlier than the Academy of Science and Technology, it was like a subordinate of the Academy of Science and Technology, as long as Du He said a word, the talents in the Ordnance Prison had to report to the Academy of Science and Technology obediently.

The establishment of the Institute of Science and Technology has not long been in urgent need of all kinds of talents.

Therefore, the two bases of scientific and technological talents of the Datang Ordnance Supervisor and the Shaofu Supervisor are the places where Du He enters and exits the most, and once useful talents are found, they will immediately do the work of digging the foot of the wall. He has Li Shimin's permission, and whoever he likes can take it away directly.

After half a month, almost all the top talents of the Ordnance Supervisor and the Shaofu Supervisor were dug up by Du He. directly let the two institutions of the Ordnance Supervision and the Shaofu Supervision regard him as a flood beast and avoid him.

No, Zheng Ang, who saw him coming to the ordnance prison, turned pale with fright, turned around and ran.

After Du He was caught, he begged for mercy as soon as he opened his mouth, and reluctantly called him Little Ancestor.

Du He touched his nose in embarrassment, "I'm not a flood beast, is it really that scary?" ”

Zheng Ang said: "Where can the flood beast compare to your old man...... Alas...... Anyway, I can't escape, just order, who do you want! He looked helpless, but the tone of his voice was like a friend chatting. Although Du He did the work of digging the foot of the wall, the results were obvious, and he was easy-going and easy to get along with. They were dug up, except for some distress, but there were no complaints.

"Don't worry, I'm not here to dig a corner, I just want to see how good my Datang's siege weapon is, this is a thousand miles of soldiers, used for a while, now is the time for them to play." Du He knew that the biggest obstacle to fighting Gaochang was the Gaochang city wall. If you want to take a fortified city, the power of siege equipment is particularly important.

He usually doesn't use it, so he ignores it, but now it's the time when he needs siege equipment to exert his power, and he has to come to see how good these siege equipment in the Tang Dynasty are, and see if they can be improved.

As the saying goes, grinding the gun in battle is not fast, but it is bright!

Hearing that Du He didn't come to dig the foot of the wall, Zheng Ang's face was a little better, and he also got the news that Datang was preparing to go to Gaochang, knowing that what Du He said was true, he led him to the Machinery Workshop Department responsible for manufacturing siege equipment.

The signing order of the Machinery Department is a man in his fifties, with gray temples, and he is still in spirit, he does not talk much, and his surname is Qian Mingjin, a very meaningful name.

"Qian Zhiling, this is Du He, the president of the Academy of Sciences, I want to take a look at the drawings of my Datang offensive and defensive equipment, you take the drawings!" Zheng Ang was very cooperative with Du He's work, and as soon as he arrived at the Orders Office of the Machinery Workshop Department, he gave the order.

The drawings of this offensive and defensive equipment belong to the first-class secret, and if they are not in their position, they don't want to obtain them at all, even if they are the prime minister. However, the Academy of Sciences led by Du He is the center of Datang technology, and he has the right to freely read any Datang technology technology.

Du He showed his token at this time, and after Qian Jin checked that it was correct, he nodded indifferently, turned around and left, from beginning to end, he didn't say a word.

Du He glanced at his back in surprise and said, "I found that whether it is the ordnance supervisor or the young government supervisor, most of them are silent characters?" ”

"It's nature! If you want to achieve some skills, who is not far away from the crowd and buries your head in practice and research? When I was obsessed with it, I stayed in the mountains for three months without saying a word. In addition to eating, drinking, and sleeping, they are all immersed in building weapons. If he hadn't been a prisoner, he would have to talk and communicate, but I was afraid that he would be no different from them. Zheng Ang boasted with emotion, nostalgic for his past life.

Du He was also faintly moved when he heard this, and it was really not easy to learn a skill.

After a while, Qian Jin took out a thick drawing that was already faintly yellowed.

"My Datang siege equipment is mainly divided into chariots, stone chariots, pointed wooden donkeys, crossbows, nest carts, wooden curtains and flying cloud ladders, etc., these are drawings." Qian Jinbao seemed to put the thick drawings on the table, and at the same time admonished: "Be careful, don't get dirty." ”

Du He also knew his mood, answered, and carefully picked up the drawings and looked at them carefully.

As a president of the Academy of Science and Technology, he actually knows nothing about science and technology, and he can convince the public by relying on the knowledge in his memory. In order to avoid making a fool of himself, he also made up for the basic knowledge in this area during this time, and the most basic drawings can now be seen and understood.

After reading the drawings, I also have a certain understanding of the siege equipment of the Tang Dynasty, and found that the technology of the siege equipment of the Tang Dynasty is very developed, and all the siege equipment is very scientific. For example, the chariot, like an armored bulldozer, is a four-wheeled vehicle, covered with rhinoceros skin, the four-wheeled vehicle can hide ten people, not afraid of arrows, rolling wood and stones, and even fire, used to transport earth to fill the moat, can go straight to the city wall, without injuring a single person, and can also go deep into the edge of the city wall, with the equipment of a short pickaxe and iron chisel to dig and destroy the city wall.

Another example is the stone car, this stone truck is like a heavy howitzer, this thing is even more scary, it belongs to the super giant, if you want to fire a cannon, you must have two hundred people at the same time to pull the rope to move, the power is huge, with the above record is, the city is cracked, and everyone is a meatloaf.

There is also a crossbow, a crossbow is a military vehicle with axles and wheels rotating at the same time, and the car is equipped with a large crossbow with a rather perverted pull force of twelve stones (about 1,400 catties). It can fire seven large and small arrows at the same time, the largest arrow arrow is seven inches long, five inches wide, the shaft is three feet long, and the circumference is five inches, and the arrow feathers are made of iron leaves. The range can reach an astonishing 700 steps, and only six words are recorded in the information about the power: it can enter the city wall for ten inches, which shows that the power is super fierce.

Pointed wooden donkeys, nest carts, wooden curtains and flying cloud ladders and other siege equipment are also quite remarkable, are in line with the scientific basis, quite practical, with these sharp weapons, no wonder when Li Shimin personally led the army to conquer Goguryeo, it only took less than 2,000 casualties to even go down to Goguryeo ten cities, and achieved the amazing results of breaking more than 40,000 enemies, if it were not for the bitter cold of Goguryeo in the end, the Tang economy was difficult to maintain, and had to retreat. In that battle alone, Goguryeo would disappear into the smoke clouds of history.

But at this moment, Du He's heart was a little disapproving, and he found that every kind of siege equipment had obvious deficiencies. He remembered that when he was reading the history of the Song Dynasty, he looked for the book "Wujing General Essentials" on the Internet. It is a military work of the Northern Song Dynasty official cultivators, the Wenchen Zeng Gongliang and Ding Du in the Renzong period, it took five full years to compile and create, and it is China's first large-scale military work of the official cultivators with comprehensive surnames, which introduces the manufacture of weapons, especially siege equipment, each of which is painted with pictures and texts.

He didn't remember the details, but he had a vague impression of the structure of the device. He closed his eyes and pondered, trying to recall some of the details of his impression, and when he opened his eyes, he found that there was one more person in the room.

A rugged middle-aged man in his forties, with thick eyebrows and big eyes, has the spirit of a northland hero.

"Who is this?" Du He was full of doubts, this is the land of military aircraft farming, and there are still people who can come and go here as freely as he does?

The middle-aged man smiled heartily: "General Du doesn't recognize Jiang, but Jiang is like thunder to the general." Jiang Xingben, the general of the Lower Zuo Tunwei, met General Du, and yesterday said that General Du's remarks at the court meeting made me admire, and I had the heart to make friends, and it was a great honor to have the honor to meet him today. ”

Du He politely said, but the color in his eyes was still undiminished.

Jiang Xingben smiled knowingly: "Before being promoted to the general of Zuotunwei, I was a general master craftsman in the court, and this time I was entrusted by His Majesty to lead my skilled craftsmen to participate in the battle against Gaochang, and I was qualified to enter this ordnance prison." ”

Jiang Xingben's words surprised Du He, he will be a master craftsman, this is the chief engineer of Li Shimin's royal palace, specially built for him, the most famous Jiucheng and Luoyang Second Palace were built by him, and he is not a simple character.

He looked Jiang Xingben up and down, no matter how he looked at it, he didn't want to be an engineer. What made him care more about it was Jiang Xingben's sentence: "Lead the skilled craftsmen under your command to participate in the battle against Gaochang!" ”

Could it be that Jiang Xingben, the general, is not leading soldiers, but a group of skilled craftsmen?

Du He asked the doubts in his heart.

Jiang Xingben nodded and confirmed his thoughts: "Just as the general thought, Your Majesty knows the importance of attacking and fighting and equipment first, so he specially asked me to form an army composed of skilled craftsmen, so that when they can be used, they can build siege equipment in a short time, so as not to miss the opportunity." ”

Du He was stunned for a while, it was too good, his father-in-law was worthy of being the first emperor of the ages, and he actually formed an engineering army.

"Oh, yes!" Jiang Xingben suddenly shouted with a row of heads: "This time, I must arrive in Gaochang first with the forward general to make siege equipment, and the time is pressing." So, let's not say much about it. Old Qian ......" He turned to Qian Jin and said: "Today, I have an idea, I don't know if it is feasible or not. You see that sulfur and resin are flammable, can you mix them together to make a new type of weapon? I've tried mixing 70 percent resin with 30 percent sulfur and getting good results, but it's too light to throw away. If you can throw it far into the enemy line or on the city wall, you will definitely achieve miraculous results. ”

Seventy percent, thirty percent!

Du He was stunned, and suddenly exclaimed: "Military gunpowder, 76% potassium nitrate, 10% sulfur, 14% wood charcoal!" Quick, get a pen and write it down! ”
