"Well, no?"

Zhang Ran looked at the steam engine fragments standing in front of him like broken porcelain.

The fragments of these steam engines were spliced together into a whole, and now Cheng Dongshan, Cui Sanyuan and others are drilling holes in the fragments, preparing screws and other things to fix them.

At a glance, it was clear that these guys were going to use this primitive way to restore the shattered steam engine into a whole, and then see if it could be used.

But Zhang Ran was skeptical.

After all, the working principle of the steam engine is not very complicated, it is just to convert steam into power.

But the crux of the matter is that the steam engine converts steam into kinetic energy, and keeps this kinetic energy strong enough, relying on the sufficient strength of the shell to compress the steam to form power.

Like Cheng Dongshan and Cui Sanyuan, using screws and other things to fix it, Zhang Ran can be sure that those cracks that have been blown up will not be able to leak air to the outside!

After all, the internal activities of the steam engine are to constantly keep the steam at sufficient pressure!

"Almost all of the shells are shattered, and there is no big problem inside!"

Hearing Zhang Ran's doubts, Cheng Dongshan Cui Sanyuan swept away the depression that he was crying before, and said with confidence: "If there is really a problem with the internal equipment, we really don't have much to do, but like the current one, it's just that the shell is blown up, then we have a way!" ”

"Tell me about it!"

Hearing this, Zhang Ran became interested.

Cheng Dongshan and Cui Sanyuan talked eloquently!

The idea was to fix as many of these pieces as possible with screws and other things tightly linked to keep the steam engine shell as strong as possible, and then fill in the gaps to keep the steam engine shell as airtight as possible.

But with the current conditions, it is impossible to think that it can be completely sealed just like this.

In addition, we have to worry about the explosion of the steam engine during the operation of the steam engine due to the excessive internal steam pressure and uneven force on the cracks on the shell.

The solution of the two is that after the screws are fixed, filled, etc., the outside of the steam engine is fixed with bluestone, and the inside is filled with cement, etc., and then solidified like pottery!

In this way, it is equivalent to putting a thick layer of shell on top of the broken shell, which can not only play a role in reinforcement, but also further solve the problem of air leakage.

"After doing it like this, I don't dare to say that this steam engine can be compared with the previous one, but it can barely be used, it is absolutely fine!"

The two of them finally said stupidly.

"With a method like yours, the high-tech steam engine has been turned into an earthen boiler for you!" Zhang Ran said angrily.

And once they follow their method, once something goes wrong in the middle general, then if you want to repair and rectify it again, it will take more time......

But judging from the current situation, there is no way out.

After all, he couldn't find any other way to get a steam engine back, so he had to let them try it first, and at the same time find a way to see if he could get an electric welding machine somewhere.

The electric welding machine was invented very early, and although there are few in China, it should be able to be found.

In another cave, Zhang Ran saw a lot of motorcycle remnants.

The twisted body, the axles, etc., were piled up in a mess.

It's a terrible mood to see good things being turned into piles of scrap metal.

Zhang Ran looked at these fragments in such a bad mood, and greeted Cheng Dongshan with a sigh: "There is still a set of wheels stolen from Xu Song in the warehouse, you can try it, can you save a motorcycle that can be ridden, and it will be convenient to use it for short-distance communication when the time comes......"

This time the detachment also brought back seventy or eighty horses, ready to form two platoons of cavalry.

Cavalry can also be used for teleportation.

Compared to horses, motorcycles can run as long as they have gas, and they won't get tired, and with the Dongcang Highway, it would be very convenient if you could really use these scraps to save two motorcycles for communication in all aspects.

Cheng Dongshan and the others agreed, saying that they would do their best.

As for the rest that can't be saved at all, it can only be dismantled by dismantling the engine, and what can be used as scrap iron is used as scrap iron, which is useful anyway, and it will never be wasted.

"These tires are blown up and tattered, and I don't know what they can do!"

Cheng Dongshan pointed to the broken motorcycle tires and inner tubes and said with a bitter smile: "It's good to use it to burn the boiler, the fire is big enough, and after burning, the smoke is a little bigger......"

When Zhang Ran heard this, he almost kicked Cheng Dongshan to death - such a good thing, he actually wanted to use it to burn the boiler!

Of course, it's used to make soles!

This time, the detachment seized too many materials, including countless Japanese military shoes.

In order to distinguish between friend and foe, these Japanese military boots all need to be disassembled, and only the soles are kept for the soldiers of the detachment to make military boots.

Talking about the military shoes of the little devils, there are actually many stories.

For a period of time, the Eighth Route Army always felt that it was definitely inconvenient for the little devil to run with such heavy shoes, so they once thought that they could take a lot of advantage in this regard by wearing straw shoes and cloth shoes.

Who knew that after a fight, he found out that the special little devil was wearing such heavy shoes and ran as fast as a dog, driving many soldiers of the Eighth Route Army like rabbits, and finally suffered a big loss.

The Imp's shoes are indeed bulky, but the Imps train a lot and spend a lot of time getting used to their shoes, so that they can completely overcome the bulky shoes in terms of quickly turning into pursuit.

Later, the soldiers of the Eighth Route Army also realized this, but because their own conditions were too difficult, even if they found the problem, they could not solve it for a long time.

However, the situation on the detachment's side is obviously different, Zhang Ran, an impostor, has full autonomy.

So as long as he can make any slight improvement in the team, he will spare no effort, and he doesn't care about whether he needs to consider friendly forces, consider the unity of equipment, etc., and only need to consider one point from beginning to end, that is, whether it will help the detachment.

Just help!

It's just that the size of the Japanese army is generally small, and the shoes are naturally not big, so only some of the soldiers can be equipped, and the military boots of the remaining soldiers are estimated to be only in accordance with Zhang Ran's previous plan, using leather and other things to increase the wear resistance and waterproofness of military shoes.

But the performance of leather in this regard, whether it is pressed by the Japanese army or hand-sewn by the detachment, is not qualified to compare with rubber.

Moreover, the soles made of rubber tires of this kind of military motorcycles, not to mention that they are wear-resistant compared to the soles doped with a certain amount of leather according to Zhang Ran's ideas, even compared with the machine-made leather soles of the little devils, they are so good that I don't know where!

Not only is the wear-resistant and slip-resistant not worse than the little devil's military boots, but the most important thing is to wear it lightly!

Zhang Ran checked it and estimated that more than a dozen tires had completely lost their repair value, and if they were used for waste use to make soles, they could make forty or fifty pairs.

In addition, the shoes made from the soles of the shoes pulled from the corpses of the Japanese soldiers can solve the problem of the quality of the military shoes of a battalion of troops, and it is not without a small contribution to the improvement of the combat effectiveness of the detachment.

Dozens of war horses are currently locked up in the back mountain, and they are eating forage in the rough construction of the horse barn at the moment.

Of the thousands of war horses, excluding those who were killed and killed, there were only so many dozens left.

Thinking of the unstoppable power of the Japanese cavalry when it charged, like a torrent of torrents, thinking that the detachment would have had the opportunity to form such a powerful cavalry, but in the end there were only so many dozens of war horses left, Kang Ting, Shi Yuan and the others were distressed.

Zhang Ran was also distressed.

However, he was distressed because he watched the war horses eat a lot of grass, which was mixed with most of the best grain.

Where is this raising horses? It's like eating your own money and drinking your own blood!

Fortunately, there are only a few dozen left.

If there were more, Zhang Ran estimated that just these war horses would be able to swallow themselves with their belts and bones.

To form a cavalry, it is not only necessary to have war horses, but also to have instructors.

After all, the cavalry is to exert combat effectiveness on horseback, not to pull out and run for fun.

"We can recruit people first, assemble the cavalry first, and wait for the main force to come over, and then I will try to see if I can ask them to help find an instructor to train cavalry!"

Zhang Ran commanded, and at the same time asked Kang Ting and the others to pay a little attention to pick out some of these war horses that were no longer suitable for use as war horses.

"These are all good war horses used by little devils, how can there be war horses that are not suitable?"

A group of people looked at Zhang Ran's eyes, as if they were looking at a fool, captain, you don't even know how to ride a horse, don't be blind to the cavalry - who doesn't know if you feel sorry for food or what?

"Do I understand or do you understand?"

Zhang Ran drank depressedly, and said in his heart, Lao Tzu doesn't understand cavalry, but Lao Tzu has seen a lot of movies about cavalry - others dare not say, just you guys, Lao Tzu definitely knows more than you!

These war horses, of course, are carefully trained by the little devil cavalry.

But when the war horse is frightened by the shelling, injured, etc., it is possible that the war horse will be seriously traumatized mentally and will never recover!

In this way, these war horses can only be used as livestock, and can no longer be used as war horses on the battlefield!

Otherwise, once they encounter artillery bombardment and so on, then these traumatized war horses will easily be frightened on the battlefield, not only can not give full play to the combat effectiveness of the cavalry, but will cause unnecessary casualties!

Speaking of which, the Ueno Cavalry will be wiped out in the Beihe Corridor this time, and it is directly related to the fact that I didn't expect Zhang Ran, a guy who is not stingy, to attack the war horse unscrupulously!

Even the Japanese army, which was known for its brutality, could not have done that!
