Gai Heiliang, Deng Fang, carpenter Lao Zheng and others, in the end, failed to rely on their own legs to reach the foot of Dingzhou City in the long and rapid march......

They were pushed by the chicken bus, or simply carried by Zhu Junlin and other militiamen.

But even so, when they arrived at the position under the city, several people were almost collapsed!

It is also a big cow, relying on the fact that he is tall and strong, in good health and young and strong, he can not only keep up with the pace of the well-trained militiamen all the way, but also look at the position in front with bright eyes and excitement after arriving......

Gai Heiliang, Deng Fang and the others, who were about to die when they arrived at the battlefield, all managed to get up the moment they stopped......

The carpenter Lao Lin immediately instructed the carpenters who came to assemble the wooden squares and the like, and Gai Heiliang was debugging the parts in it, and at the same time carefully fixing the most important things, the rubber boys cut to two fingers wide, on the shelves......

Deng Fang, on the other hand, led several students from the Ministry of Chemical Industry to carefully carry a pile of clay pots, all of which were solidified into a paste of napalm gasoline......

Looking at the things that were gradually taking shape under the joint efforts of Lao Lin and other carpenters, Gai Heiliang and others, Zhang Ran's face couldn't help but be a little blue......

For several hours, he was looking forward to what weapon Gai Heiliang and the others had invented—he even wondered if Gai Heiliang had invented the cannon!

But this thing in front of me is clearly a trebuchet that has been eliminated for I don't know how many years - and it's a torsion trebuchet, not the counterweight kind!

Zhang Ran looked at Gai Heiliang with gloomy eyes, and said in his heart, You are also the first guy to invent a cannon in the history of our army's military industry - you are going to fool me with a trebuchet?

The most important thing is to cut the tires that Lao Tzu is going to use to drag guns in the future!

Gai Heiliang was also a little embarrassed, after all, he didn't make a cannon as a weapon expert, but he made a trebuchet that his ancestors invented thousands of years ago......

But no matter how embarrassed he is, Gai Heiliang will never think that the role of this trebuchet in the battle in front of him is smaller than that of a cannon!

"Don't explain, I'll ask you a question!"

Zhang Ran interrupted Gai Heiliang's words angrily and said, "Do you know what the main problem of the detachment is that the devils under this city have been unable to attack for a long time?" It's about the distance - not only on the ground, but also on the wall more than ten meters high, and there are tanks of little devils rushing out of the city at any time......"

Once the fighters approached, they were faced with the indiscriminate bombardment of the devil's multiple firepower!

If there is artillery, it is one of them to be able to support it with long-range artillery fire, and most importantly, to be able to pull out the fire point of the devils on the head of the city, or suppress the fire of the head of the city......

Trebuchets obviously don't work!

"Why can't trebuchets work?" Gai Heiliang asked rhetorically unconvinced.

Zhang Ran said angrily: "Gai Gong, I may not know as well as you when you talk about professional knowledge such as cannons, but this trebuchet, don't fool me - the maximum bomb throwing distance of the trebuchet is only more than two hundred meters!" ”

If the distance of more than 200 meters can suppress the fire of the city, then do you still use trebuchets?

The detachment's flying thunder cannon modified from gasoline barrels can hit up to nearly 300 meters, okay?

"Captain, why do you think I'm going to cut the tires you were going to use to tow the cannon and remove the rubber and use it on this trebuchet?"

Gai Heiliang waved his hand very proudly, and several full-time weapon tests, including the previous test of the flying thunder cannon, were all completed by him, and the testers immediately stepped forward and snapped and said loudly: "Captain, this trebuchet built by Gai Gong's organization, after testing, the farthest bomb throwing distance has reached 480 meters - even if it is worse, 400 meters is stable!" ”

Forehead?

Hearing this, Zhang Ran was overjoyed!

The effective range of the rifle is only about 400 meters, and 400 meters away, it depends on skill and luck!

The distance of this trebuchet is beyond the effective range of the bullet - although it is not comparable to a dozen regular artillery fire of several kilometers, but it is indeed enough to suppress the fire of the city!

"But this trebuchet has no precision!" Zhang Ran asked another question.

It's not like he's nitpicking!

Historically, trebuchets were eliminated because the accuracy was almost non-existent!

If you can smash people, that's luck, and it's normal if you can't smash them!

The role of trebuchets on the battlefield is more of a deterrent than a kill - and in today's war, the soldiers can't be frightened by the indiscriminate bombardment of aircraft and artillery, can they still expect to be intimidated by trebuchets?

"The trebuchet throws stones, it really can't scare the devil!"

Gai Heiliang confidently stretched out his hand and pointed: "But the point is, what we lost is not a stone......

He was referring to the huge pile of jars made from the kiln!

The canister has an oval shape, which clearly refers to the shape of the cannonball, and has the effect of reducing drag.

One of the ends had a small opening the size of an egg, which was so stuffed that traces of a fuse could be seen in it.

"Captain, our clay pot not only contains a large amount of napalm, but also explosives!"

Finally waiting for the opportunity to show off, Mao Diamond immediately stepped forward and pointed to these jars to popularize the doorway to Zhang Ran.

These explosives not only allow the clay pot to explode and start a fire, but also allow the napalm after the explosion to spread to a larger area......

"I know that!"

Zhang Ran waved his hand impatiently, pointed to those clay pots and asked Mao Zhuan: "I just want to know, these clay pots are so fragile, if they fall to the ground and break before the explosion, won't it be in vain?" ”

"Captain, if we can't even think of this problem, then do we have the face to run so far to send these things over?"

Gai Heiliang Mao Drill and the others snorted with a pout, and said with a very arrogant attitude: "Who said that our jar must explode on the ground?" Can't it explode on top of the devil's head? ”

"You mean, air blasts?"

Hearing this, and thinking about the napalm once it caught fire, it would not be finished if everything that could be burned was not finished, Zhang Ran's scalp couldn't help but tighten, and his heart groaned......

In this case, you also need the precision of a hair!

But he's still a little worried!

"Captain, don't think about it, we've all thought about what you're worried about - aren't you just worried that when this bomb is dropped, it will explode in advance or fall to the ground before it explodes?"

Mao Diamond, Gai Heiliang and the others looked like captains, do you think that our Tianyin Tmall is engaged in research and development in the back mountains, and it is not bad to eat for nothing and not work, so he pointed to a small opening in the loading position of the trebuchet and said: "Look at what this is?" ”

A few testers immediately stepped forward to demonstrate!

After the canister is put into the leather buckle of the bomb, the fuse on the mouth of the canister is fastened with a small silk thread and the small mouth!

Zhang Ran immediately understood that Gai Heiliang Mao Diamond and others were so arrogant, and they did have the qualifications to be arrogant - they really worked hard!

Zhang Ran beware of the jar exploding in advance, or not exploding after landing, of course it makes sense - after all, it is a distance of four or five hundred meters to throw it out, but the key to the problem is that the speed is too fast, and it will be a fleeting thing in the blink of an eye!

It's too late for the fuse to be lit, and that's not going to work!

But this design on the trebuchet completely exempted Zhang Ran's worries!

The flight time of the thrown canister in the air is roughly the same.

These guys cleverly only calculated the time the canister was in the air, and then left an equal fuse - using this small silk thread, when it was fired, when the canister broke away from the buckle, it directly pulled and ignited......

The time of the explosion of the jar is easy to control!

"Minister Mao, cover worker!"

Zhang Ran sincerely thanked everyone and said: "With you here, it is the luck of all the soldiers of my Jindong detachment, and the luck of all the fathers and villagers in our base area!" ”

The originally arrogant Mao Diamond Gai Heiliang is a little embarrassed at the moment!

Mao Diamond modestly said that whether it was the trebuchet or the moment the jar was pulled out of the leather buckle, it was the credit of Gai Heiliang, and he was the one who beat the hand......

Gai Heiliang had an expression of disgrace on his face, but some said that it was all because Deng Fang and others got the napalm out!

If it weren't for napalm, no matter how many ideas I had, I would have doomed this trebuchet to be just a chicken rib!

Zhang Ran then turned to Deng Fang, ready to thank them for their efforts on behalf of the 40,000 compatriots in China - but seeing Deng Fang's well-deserved expression, Zhang Ran didn't want to say anything......

Deng Fang, who was waiting to be praised, almost choked up, and his angry beard was cocked!

As the minutes ticked by, the wee hours of the morning were fast in coming!

Four or five assembled trebuchets finally revealed the whole picture in front of Zhang Ran!

Because rubber is used as a torsion skew and there is no need to use counterweights, after the trebuchet is strangled with a winch, the whole trebuchet forms an oblique triangular plane!

Not to mention this night, even during the day, it is estimated that it is not easy to be seen, and the target is extremely small!

And under the frame of four or five meters, there are four wheels, which can be pushed to facilitate movement, and can follow the attack of the troops to get close to the city!

"Good stuff, good stuff!"

Zhang Ran and everyone who saw the purpose of this thing were excited!

Although this thing is still suitable for use in fixed confrontation positions due to its large size, and is not suitable for the requirements of mobile guerrilla warfare, it is still an excellent weapon - especially the napalm with the air explosion......

It's terrifying to think about!

In the city, gunshots and fighting broke out again, and it was obvious that Harada was fighting with Yuan Zhenfeng's remnants again.

The Japanese troops at the head of the city were patrolling sparsely, and exaggerated snoring could be heard from afar......

"The little devil is playing a conspiracy with us!"

Zhang Ran looked at Kang Ting and the others and laughed fiercely, waved his hand fiercely: "Prepare to fight, let's not play conspiracy this time, let's also conspire with the little devil Yang...... Use your equipment advantage to crush them! ”
