At the mouth of the Zhanghe River, a new manor has been built, ditches have been dug in the garden, and metasequoia has been planted on both sides of the ditch. In the beginning of summer, a handful of sharp shoots were drawn, and the green was so strong that at a glance, there were two green lines around the garden, which was particularly beautiful.

There are signboards hanging in the garden, there are door cards at the entrance, and seven or eight Zhuang Ding are missing arms and legs, but the horizontal knife around them is not vegetarian, and there are no thieves who come to make a joke on such old soldiers.

"Wang Taishi, this crossbow ...... It's too big. ”

Old Man Wang was still arranging the groove of soil method coking a while ago, but now he is calculating something else. The head of the Zhanghe estuary of the China Resources, when he looked at this object, the sweat on his forehead suddenly came down.

"Big? It's not big, it's not big, the old man originally calculated that he could shoot an arrow weighing one stone, but unfortunately this machine is expensive, and I am afraid that it will be distressing. Wang Xiaotong copied his hand and patted the ballista receiver made of fine iron, "Moreover, the beef tendon and deer tendon are not easy to boil, and it is difficult to maintain when placed at sea." The old man had to reduce the specifications and make such a small crossbow......"

Looking at Wang Xiaotong, who looked sorry, the head of the Zhanghe estuary who was drenched in cold sweat whispered: "Wang Taishi, this is ...... It's a crossbow, not a bow. ”

"Afraid of what? The Dingxiang army is in urgent need of sharp weapons to attack the city and pull out the village, and it is an expedient measure for the governor to obey the power in a hurry. "Old man Wang is also very insightful about shamelessness.

Besides, it's just a ballista, and it's not a thunderbolt, what are you afraid of......

Thinking of the thunder, Wang Xiaotong's eyes lit up, and he decided to make a pre-loaded box for firing projectiles in the place where the ballista was slotted, and then ignited it. Just shoot it out, it should work well.

Think about it. Wang Xiaotong asked people to fix the crossbow groove slider, and several launch angles were preset on the bracket. Each launch angle. It's all well documented.

"The movement of the sky, day and night is called the week, the so-called cycle and the beginning, and so on. Today, it is about 360 degrees in a week, and it is 180 degrees in straightness. The middle to the first line is two right angles, about 90 degrees. ”

Old man Wang taught the steward of the mouth of the Zhanghe River with a confused face to teach advanced postures. However, the steward's posture is not right. I didn't understand it, so I had to be stupid, and I repeatedly said that Wang Taishi was awesome and didn't explain.

"Someone, forty-five degrees."

Then the bracket was raised, and a cast iron tenon was pulled out, and when it was in place, it was inserted again.

Several craftsmen were busy, and a stone bullet had been placed on the slider with the Arabic numeral 30 written on it.

The winches on both sides of the receiver rotate. The crunching of the cow tendons made the entire ballista tremble, and after clearing the field, Old Man Wang took a sip of warm sugar water and smacked his lips: "Put." ”

Bang!

There was a loud bang. The entire ballista fuselage shook backwards, and the soft earth was a few inches lower. The craftsmen who had never seen the world were shocked for a long time. I saw the stone bullet cross a trajectory, and there was a muffled sound. It slammed into the flamboyant grass in the distance, splashing several large pieces of turf.

The site is paved with cinders. The line was drawn with lime again, and it was clear at a glance.

"Old man, take a look."

Wang Xiaotong picked up a pair of tortoiseshell-framed reading glasses and looked at them fixedly, "Hmm...... The old man thought that there would be one hundred and fifty zhang, but now it seems that there is not even a hundred. ”

After thinking about it, Old Man Wang observed the structure of the ballista and said with emotion: "The cost is expensive, but it is not very satisfactory." ”

A few veterans from the Dingxiang Army who were waiting on the side, their faces were white, and their hearts were all making up for it, if the barbarians shot this thing, it would be the stainless steel milk cover worn by the captains, I'm afraid I won't be able to eat it, right?

Then after thinking about it, the old man of the Lying Groove King was still not satisfied with this effect? A hundred zhang is good! The Tang Army's hard bow has reached thirty zhang, which is purely a miracle of vigor, and the barrage must be thick!

If the two armies face each other, the two rows of ballistas shoot the damn first, the foot soldiers shoot with bows, and the army array advances layer by layer, the picture is too beautiful to watch.

Putting away the reading glasses with tortoiseshell frames, Wang Xiaotong said to several assistants: "Try each angle in turn, test all kinds of projectiles one by one, and record them." ”

"Yes, Wang Taishi."

Then Old Man Wang took a few other assistants with his hands behind his back and went to the next door: "Today, let's do the thunderbolt car first, the crossbow machine is really exquisite, and it takes a lot of effort." ”

The site next door is bigger, and there is a hill and then a row of large wooden structures. A thunderbolt cart towed by manpower, that is, a traditional stone thrower. There is also a catapult stone thrower made of bamboo tendons, the structure is very strange, but the effect is very good, because it saves money.

But what satisfies Wang Xiaotong the most is the counterweight catapult, which is easy to use, very easy to use.

Because of the needs of western Liaoning, Wang Xiaotong designed counterweight catapults ranging from 40 to 200 stones for the cities of Goguryeo. According to the characteristics of Goguryeo Fortress, different stone bombs were also designed.

One of the stone bullets, Mr. Wang is particularly fond, this stone bullet is first grooved by a hydraulic milling machine, so that the stone bullet has many irregular grooves. Then several small stone projectiles come together, and after being projected, they hit the city wall, and they will immediately split and shoot out in all directions.

For this reason, Wang Xiaotong specially borrowed more than 100 pig heads from Cangzhou to test the effect, and the effect was ...... Very satisfied.

Either death or injury, it is simply a murderous weapon.

"Wang Taishi."

Seeing the old man coming, a group of assistants all consciously got out of the way, and several students who were recording the data saw him and shouted respectfully: "Sir." ”

"Well, the old man just looks."

Wang Xiaotong picked up the experimental record, flipped through it for a while, and was very satisfied, "The rammed earth city wall, except for flooding, the old man really can't think of any good way." Alas, the power of the thunder is weaker, if it can be a hundred times more powerful, it will definitely be able to collapse the rammed earth city wall. ”

“……”

The disciples didn't speak, they all looked. Since Mr. Jia got on the thief ship of the man in Liangfeng County, he has not had a normal day, and now, he is completely crazy.

Originally, when I was plugged in, I said that I was learning advanced mathematical postures, but I don't know if the posture is wrong or what, since I came to Hebei, it seems that mathematics is used on how to kill people. And now killing people depends on calculations, quantitative killings......

"But the old man can't understand this, it's a pity." Wang Xiaotong was full of emotion, "I only hate being born seventy years early." ”

"Mr. Why do you say this, Mr. is the old man who is determined to be thousands of miles away, if there is no Mr., how can the thistle workshop stand so quickly? Mr. is old and strong, and the students and others are very admired. ”

The students hurriedly patted the sycophants, and the old man was in a much better mood, and then stroked his beard and sighed: "My life has an end and there is no end to learning, knowledge is like the sea, and my generation is like a boat." How fast it is to cleave the waves! ”

Then he turned to a few students and said, "Put twenty fat pigs at one hundred and fifty zhang." ”

"Yes, sir." (To be continued.) )
