Although he didn't know Chen Ying, Ge Tong knew his own clan elder Zhao Boying. Seeing Zhao Boying following behind Chen Ying, staggering the position of the lower half of his shoulder, it was obvious that Chen Ying's identity was higher than Zhao Boying. In Ge Tong's eyes, Zhao Boying, the old man of his family, is already a great man. When Zhao Boying was young, he served as a minister in Shanyang County. The characters who can make Zhao Boying grovel, at least not something he can offend.

Ge Tong is a craftsman for generations, and the skills under his hands are also good. Of course, his temper is not good, if Chen Ying's words are replaced by his ordinary people, Ge Tong will definitely let him roll as far as he can. However, since he saw that Chen Ying's identity was not good, and he scolded Chen Ying, he must have been unable to get along with himself.

Ge Tong saluted Chen Ying and asked softly, "I don't know what cannon your nobles want to build?" It's not a little old man who blows, I've been a craftsman for generations, from a single cannon to a maximum thirteen cannons. ”

Since the invention of the trebuchet in China in the Western Zhou Dynasty, it has been the use of manpower to pull the tips (cannon tips) attached to the crossbar at a place far away from the catapult. This situation has not changed for more than 2,000 years. It was not until the Mongol invasion of the Great Song Dynasty that the counterweight trebuchet was brought to Xiangyang for the first time, and the traditional trebuchet of ancient China slowly withdrew from the stage of history.

Of course, the traditional manpower stone throwing machine has very low power utilization. For example, the seven-pin cannon needs 250 people to pull at the same time to throw the stone projectile out, but in actual operation, it is almost difficult for these 250 people to move in unison and force in one place.

However, although the principle of the counterweight trebuchet is the same as the traditional Chinese trebuchet, it adopts the principle of leverage, but it is equipped with a heavy object at one end, and the other end is equipped with a stone projectile to be launched, and one end of the ammunition must be pulled down with a winch, pulley or directly with manpower before launching, and the other end with the heavy object also rises at this time, and after the stone bullet is placed, let go or cut the rope, so that one end of the heavy object falls, and the stone bullet is also thrown out with the trend.

Compared with the traditional human trebuchet, this counterweight trebuchet has the obvious advantages of fewer operators, high efficiency utilization rate and greater power.

Although Chen Ying did not have the intention of storming Yanmen Pass, it did not mean that he did not want to take this opportunity to cultivate the siege combat ability of the Dingyuan Army. In contrast, in the next period of time, he is likely to be transferred back to Guanzhong or the Central Plains by Li Yuan to participate in the battle against Wang Shichong.

Fighting against Wang Shichong is completely different from fighting the Turks. Fighting against the Turks, many times in the field. Whose horse is fast and sharp. However, to fight against Wang Shichong, you need to consider the longitudinal factor, and more often than not, you need to participate in the attack and defense of the city. Wang Shichong owns more than 100 cities in the Central Plains, if he doesn't have a strong ability to attack fortifications, it is not a joke to think of getting military exploits.

Hearing Ge Tong say that he would make trebuchets, Chen Ying was overjoyed and said: "It's better, come here, prepare paper and pens for me, and I'll draw you a drawing......

Ge Tong waved his hand and said: "So that the nobles know that Xiao Lao'er has been a craftsman for generations, from the smallest single-tip stone cannon to the largest thirteen-tip stone cannon, the size of all kinds of cannons is installed in Xiao Lao'er's head, you only need to tell Xiao Lao'er that you need to build a few cannons!" ”

Chen Ying smiled faintly: "I don't want to build an ordinary trebuchet, but to build a new kind of trebuchet, which can throw heavier stone projectiles farther and more powerful!" ”

Ge Tong asked puzzledly, "Is there still such a trebuchet?" ”

Chen Yingdao: "Of course there is! ”

As soon as he heard this, Zhao Boying's eyes rolled and he glanced at a young man with clear eyebrows behind him, and the man nodded knowingly. Turning to leave, after a while the young man panted for a knife of hemp paper, and a thin wolf pen in the pen. Chen Ying reached out to take the paper and pen, and the young man knelt on the ground with great interest, using his back as a table.

Chen Ying is not hypocritical, writing in this era is not like that of later generations, there is no table, and he has no way to write, let alone draw.

Zhao Boying poured some from the water bladder into the inkstone and gently grinded it.

After Chen Ying's pen was full of ink, he began to draw a drawing of the counterweight trebuchet on paper from memory.

Just when Chen Ying lightly sketched out the general figure of the counterweight trebuchet with a few strokes, Ge Tong's face showed an ecstatic look, and the old man Ge Tong, who had white hair, looked at Chen Ying with strange eyes, admiration, shock, and absurdity...... And so on.

Chen Ying looked at Ge Tong, whose eyes were hot and dangerous, and Ge Tong's eyes at this time were like a virgin who was ten thousand years old and saw the best beauty. Suddenly, Chen Ying thought of a possibility in his heart, and Chen Ying secretly thought: "This old boy can't be an old glass, right?" ”

After a long time, Ge Tong's breathing became rapid, and a flush of excitement appeared on his face. Chen Ying subconsciously pressed his hand on the handle of the knife, if this old glass dared to come nonsense, Chen Ying would not mind killing.

"Noble, you are really a genius!" Ge Tong's expression made everyone even more misunderstand that he had a tendency to turn his back on the mountain. At this time, Ge Tong said excitedly: "Little Lao'er asked himself that he has been manufacturing impregnated weapons for decades, and no matter what kind of weapons in the world, he can be regarded as proficient. The trebuchet painted by the nobleman, although only slightly changed, but the design is ...... It's unheard of......"

"As for it!" Chen Ying smiled disappreciatively. It's a pity that he really didn't know how gunpowder was made, otherwise it would have knocked their jaws off the ground.

However, despite the minor changes, the advantages of the counterweight trebuchet are clear. Under the effect of labor-saving by taking the movable pulley block, even if there is a 10,000-pound counterweight, a person can easily pull it up. In this way, the counterweight trebuchet can control the operator to less than ten people. In the same space, more trebuchets can be assembled by saving manpower.

Ge Daodao: "Little Lao'er promises to make this trebuchet in one day, no, two hours." ”

As he spoke, Ge Tong picked up the drawings and ran into the distance in three steps and two steps. As a generational craftsman, Ge Tong saw at a glance the advantages of Chen Ying's drawing paper. Of course, it will take a long time to change from the pattern on the drawing to the real thing.

In fact, weapons have been constantly developing, in terms of crossbows, the Warring States crossbow, the Han has rhubarb, the Three Kingdoms is the Yuan Rong, the foot Deng crossbow, the Wei and Jin Wan Jun, etc., generation after generation is more exquisite and sharp; In terms of armor, the pre-Qin leather armor, the Han Dynasty armor, the Wei and Jin scale armor, and the Tang Dynasty Mingguang, one generation is stronger and heavier than the next.

Despite this, the ancient production and manufacturing process was too backward, and the production cost of each set of armor was quite high, and it was acceptable to equip a part of the army, but the financial resources of the whole army were not affordable by ordinary people.

Chen Ying watched Zhao Boying open his mouth to speak, especially his old face full of ravines, and the wrinkles were deeper at this time.

smiled slightly: "Elder Zhao has something, but it doesn't hurt to say it." ”

Zhao Boyan stretched out his hand and pointed at the young man who was serving as Chen Ying just now and said, "General, this is the dog Zhao Haoxin." The dog is coarse and literate, if the general sees him as an eye, let him follow the general and serve left and right. ”

Chen Ying sighed slightly: "Pity the hearts of parents all over the world." ”
