After returning to the Gaoling Marquis's Mansion, Cao Liang came to the study silently, and Fang Bu put down the scrolls and retreated.

Cao Liang went, but "disappeared" for several days, which made Yang Huiyu very anxious, and she was slightly relieved to see Cao Liang come back safely, but it seemed that Cao Liang's expression was melancholy, Yang Huiyu stepped forward and asked softly: "What happened to make the husband so depressed?" ”

"Mr. Ma has passed away." Cao Liang said heavily.

"Which Mr. Ma?"

"Mr. Ma Jun and Mr. Ma Deheng in the previous matter."

Yang Huiyu sighed lightly, she was born in a famous family, and she still knows a little about the affairs of the court, and said: "Mr. Ma is the most ingenious person in the world, and he once made a hundred plays for the first emperor, which is amazing, but I didn't expect it to be ancient, sad and lamentable, it turns out that my husband has not come back for a few days, and he is going to mourn Mr. Ma." ”

Cao Liang said: "I had the help of Mr. Ma before, and got the drawings of the repeater and the catapult, and made according to the drawings, so Mr. Ma was able to break the Huns, so Mr. Ma is indispensable." When I returned to Beijing this time, I wanted to visit Mr. Ma, but I didn't expect to get the news that Mr. Ma was seriously ill before I made the trip. Da Wei lost Mr. Ma, not only lost a skilled craftsman, but the world is stupid and does not know the difference between beautiful jade and stubborn stone. Mr. Ma was poor all his life, obsessed with research and invention, and did not interact with the powerful, so after his death, the condolences to the guests were numerous, and I was grateful for Mr. Ma's virtue, so I stayed for a few more days and returned after the burial. ”

Yang Huiyu said: "Yes, since the husband is favored by Mr. Ma, he should lend a helping hand." Yang Huiyu saw the scrolls of the case and asked, "Hey, what is this?" ”

"This is Mr. Ma's relic." Cao Liang said, casually opening a roll of paper.

As expected, what was drawn on this roll of paper was a construction drawing, Cao Liang glanced at it, couldn't help but be stunned, and immediately showed a look of surprise.

Originally, I thought that Ma Jun was old, and his physical strength and energy were greatly reduced compared to before, and after studying the counterweight catapult, it would be difficult for him to have any more masterpieces, but he didn't expect his creative energy to be so vigorous, and he could continue to have new inventions when he was over seventy.

Yang Huiyu couldn't understand what was on this drawing, but looking at Cao Liang's expression, what was drawn on this drawing must be something extraordinary, and she couldn't help but ask curiously: "Husband, what is this?" ”

Cao Liang smiled and said: "This thing is called a crossbow car, so the name suggests, it is a ballista that can continuously fire crossbow arrows, if the infantry array is equipped with this thing, why not be afraid of the attack of the enemy's cavalry." ”

The ballista, also known as the bed crossbow, is a heavy weapon equipped with infantry battle arrays, which can be used in siege operations and field battles, with a long range and great power, but the bed crossbow has a fatal flaw that is a single shot and a single shot, and it takes a certain amount of time to change the crossbow arrows every time, so it is greatly reduced in efficiency.

In addition, the bed crossbow is relatively bulky and has poor mobility, if you want to use it to deal with the cavalry who moves like the wind, it is difficult to be effective, so generally on the battlefield, the bed crossbow is rarely used to fight against the cavalry, but is mainly used to siege the city. Although the crossbow arrows of the bed crossbow are also called arrows, they are as thick as the rods of a gun, and they can be shot into the city wall during the siege, forming a treadmill arrow, and the besieging soldiers can step on these arrows to climb the city wall.

The drawing of the repeater cart drawn by Ma Jun perfectly solves the problem of the efficiency of the bed ballista.

The crossbow and the individual crossbow are the same in principle, except that one is a heavy weapon and the other is a light weapon.

However, it is easier said than done, but it is even more difficult to implement, after all, the individual crossbow is small in size and easy to carry, and it will not add much additional burden to transforming it into a crossbow.

But it's not easy to change the ballista, after all, it's a big guy, and any change is extremely difficult, so if you want to develop a ballista car, you must completely overturn the structure of the original ballista and redesign.

Such brain-burning work would not have been possible without the accumulation of strong mechanical knowledge and the design experience day after day and year after year.

Due to the contempt for scientific and technological inventions in this era, there will not be a large number of talents in this field, and only people like Ma Jun, who are obsessed with mechanical manufacturing, can realize this kind of invention and creation.

If Ma Jun's repeater is improved and developed on the basis of Zhuge repeater, then this repeater car is completely Ma Jun's own creativity, when he has reached his twilight years, there can still be such an amazing invention, Cao Liang can't help but sigh with emotion, if Ma Jun's life is extended for another ten years, he can create more miracles.

Cao Liang looked at the drawings, and the repeater was already on the paper, following the repeater and the catapult, this is undoubtedly a weapon that will change the war.

If the individual crossbow is compared to a light machine gun, then this kind of crossbow car can be called a Maxim heavy machine gun, according to Ma Jun's design, the arrow compartment of the crossbow car can store up to twenty crossbow arrows, exquisite mechanism design, after each shot of a crossbow arrow, the crossbowman flips the switch, you can carry out the loading of the next crossbow arrow, and the interval between each two crossbow arrows is not more than three breaths at most.

Such a rate of fire is quite terrifying, even the most skilled archers can't shoot a second arrow in three breaths, but even a ballista can do it.

If dozens or even hundreds of ballista carts were pushed to the forward positions of the battlefield, such a dense shooting would probably be a nightmare for any army, and even the fast cavalry would not be able to survive under such a dense rain of arrows.

What's more, the crossbow cart is a weapon that has a longer range and more power than the bow and arrow, and the crossbow arrow like the barrel of the gun, no matter who it shoots, will not feel good, such a strong penetrating power, even if it is wearing seven layers of armor, it will not help, and the arrow shaft of the ballista can completely ignore all means of defense.

The advent of the ballista will greatly improve the combat capability of the infantry, whether it is a partial car formation, a spear such as a forest formation, their strongest point lies in defense, if the enemy does not attack, no matter how strong the defense is useless.

Ballistae, on the other hand, have more than twice the range of a normal bow and arrow, and cover a greater range of attacks, allowing them to be used as a weapon against cavalry.
