In the hangar carved out of the mountain, Xu Kunjun is still busy.

All kinds of wood scraps were piled up, and those were all used to replace some of the unfound aircraft remnants with wooden components according to Zhang Ran's previous instructions.

But it became clear that the idea of replacing aircraft remnants with wood fittings would not work.

"It's not just that the wood we can find here is not strong enough to support the take-off and operation of the fighter, but more importantly, the components we need for the fighter cannot be replaced by wood at all......

Xu Kunjun said, there was not much dissatisfaction on his face because Zhang Ran had wasted time with his blind ideas, but more strange......

After all, although Zhang Ran has two knives for everything, and he seems to know a little bit of everything, he will definitely make a mess if he really lets him do it himself, after Deng Fang's propaganda, the high-level of the detachment has long been known to everyone.

But at the same time, although Zhang Ran said that he was invincible in the world, the directional suggestions that often passed through his mouth were almost all proven to be effective methods, and they were also well known.

Only this time, Zhang Ran's proposal to repair the wooden components of the fighter plane failed completely, which had to surprise Xu Kunjun.

Zhang Ran was embarrassed.

For example, the suggestions for the rest of the people, such as the tower cylinder method sulfuric acid, such as using the mold to make the model first and then the stamping machine, punching and forging machine, these are either those that I have learned and know a little bit about, or I can easily see and touch them......

And airplanes, even in the era when they traveled over, although they were not uncommon, they were not something that anyone could touch!

I haven't learned, and I haven't been exposed to it in the real sense, it's completely because I saw the little devil's plane in the movie that there is wood, so I just have a mouth...... It's not surprising at all.

Fortunately, even if some parts of the aircraft are replaced with wood components, it is not so simple to assemble this aircraft, so Zhang Ran did not take it too seriously except for secretly swearing in his heart that he would never make up his mind in this kind of high-precision technology in the future.

In addition to the wood, there were many remnants of the aircraft in the hangar.

These are all in the Pingtongguan War, when there was air support at the beginning, the wreckage of the fighter planes that were destroyed by each other, adding up to three or four, was brought back by ants when the militia and civilians secretly cleaned the battlefield.

Judging from the painted markings on the wreckage of the fuselage, these planes should all be the wreckage of the fighter planes of the chairman's troops, and there are no wreckage of the little devils' fighters at all.

From the bullet holes on the fuselage, Zhang Ran was enough to imagine how those pilots had been outnumbered by the enemy, through the blockade of countless little devil fighters, and supported Ping Tongguan, and he could imagine the grief and indignation in their hearts when they saw the Chinese soldiers below being bombarded indiscriminately by the little devil's aircraft artillery......

It can also be imagined that they fought to the death with one enemy and ten in the long air with the devil's fighter group, and were finally shot down and martyred......

Now, the wreckage of these planes is quietly spread out in this hangar.

Zhang Ran really hopes that part of these wreckage will pass through Xu Kunjun's hands and successfully make the relatively intact fighter of the detachment rise again, and carry the will of those dead pilots to roar in the sky again!

Tell those little devils that as long as there is still a Chinese alive, in the land of China, there will be no part of their little devils who are rampant!

Both on the ground and in the air!

It's just that although the wish is good, it is quite difficult to realize it!

Although now, because of the wreckage of these fighters, the spare parts that need to be replenished for the repair of the aircraft should have been able to be found, and after tasting the power of the old goat's tongue, the two little devil pilots Yoshida Tadashi and Fujita Ichiro are now extremely honest, and when they need to be used, the aircraft is full of everything......

It is equivalent to the current detachment's research in aircraft, together with Xu Kunjun, a mechanical expert, there are already three professionals.

But according to Xu Kunjun's estimate, in less than a year and a half, there is still no hope that the wreckage of the plane will be successfully repaired and finally fly......

"These two guys, are they really that honest?"

Xu Jin looked at Yoshida Tadashi and Fujita Ichiro, who were busy in the hangar, and he was still somewhat uneasy, and he had a feeling of luring wolves into the room.

"In addition to the old goats, Dr. Han also gave them some minor surgeries before leaving......

Xu Kunjun said with a smile: "Now that these two guys have their hands and feet together, they have a total of four fingers left, and it is estimated that even if they want to be dishonest, they shouldn't be able to do much harm, right?" ”

"Han Jinshan, this guy ......"

Hearing this, Zhang Ran couldn't help but feel numb in his scalp, and felt that this guy was too cruel.

"Dr. Han came two days ago, and as soon as Tadashi Yoshida and Ichiro Fujita saw Dr. Han, they peed their pants on the spot......"

Xu Kunjun held back a smile and said: "So captain, don't worry, now these two guys are more docile than lambs!" ”

"In short, you still have to be careful, don't be careless!"

Zhang Ran finally instructed, and then told Xu Kunjun his intention, since there is no progress on the plane side for a while, he will take it slowly and give priority to cooperating with Gai Heiliang's side to develop the task of towing the nose of the vehicle and making the tank gun move.

After arranging these, Zhang Ran returned to the detachment.

Along the way, there are large fields.

The corn is already flowering, the sorghum is already beginning to tassel, all the crops are thriving again, and in another two months, it will be the harvest season again......

Thinking that when he and the others led the team to leave, the corn sorghum seedlings were no more than a foot high, and Zhang Ran, who was walking in the green gauze tent, couldn't help but sigh that time had flown by......

The work of the fertilizer plant and the copper smelter is being carried out overtime.

The copper in the warehouse is now completely gone.

As soon as the copper blocks were smelted, they were all sent to the back mountain, where they were directly turned into bullets, or into shells under development.

However, the finished fertilizer products in the warehouse have been piled up more and more!

The blockade of the periphery of the base area by the little devils has been gradually strengthened!

In addition to Lu Song, Yangquan Qingping Yuanguang, which are close to the detachment's guerrilla areas, it is difficult to transport the fertilizer produced by the detachment to Gaolin, Lingjiang or the Longyuan area where the division headquarters is located......

In the first half of the year, there were only a handful of teams that came to transport fertilizers, and the detachment seemed much quieter.

This kind of fertilizer, which is almost a semi-finished product, is unqualified in packaging and stored for too long, which can easily cause the loss of fertilizer efficiency......

Ma Chengbang and others, as well as the cadres of various townships and towns in the base area, spared no effort to sell chemical fertilizer, but the effect was very unsatisfactory - because chemical fertilizer had to be exchanged for grain!

Zhang Ran will be worried that after the fall of Pingtongguan, the devil will concentrate his forces to deal with the detachment, and the villagers in all walks of life are also worried!

This season's fertilizer, the villagers' fields have been applied enough, and then store the fertilizer, it will be used for the next season's crops!

And the next season's crops, whether they will be planted for themselves as before, or for the little devils to work, no one knows......

Therefore, instead of hoarding fertilizers to make food growth cheaper for nothing, everyone wants to save more food.

Zhang Ran is clear about these.

Therefore, although he was worried about the plan to let the detachment stock more grain for emergencies be greatly discounted because of the unfavorable sales of chemical fertilizers, he did not blame Ma Chengbang and other dealers and grassroots cadres in various villages and towns too much, but just let the fertilizer factories continue to maintain production and have more stocks.

Although the time of inventory is too long, the loss of fertilizer efficiency is too great, but when it is used, it is better than no chemical fertilizer at all.

On the other hand, Zhang Ran also urged Deng Fang and other personnel from the Ministry of Chemical Industry to take this opportunity to conduct in-depth research on chemical fertilizers to see if they could find out how to reduce the volatilization of chemical fertilizers during storage and maintain fertilizer efficiency for a longer time......

The blockade of the little devils has not only brought about the problem that the fertilizer produced by the detachment cannot be sold, but it is becoming more and more difficult to transport ammunition......

Although preparations were made for the arrival of all this, and all kinds of necessary goods were stocked more than a year ago, the supply of all kinds of goods was still very abundant within the detachment.

But after Zhang Ran knew that all aspects of procurement had become difficult, he still issued a purchase restriction order as soon as possible!

Although at the same time as the purchase restriction order, Zhang Ran also issued an order not to take advantage of this trend to hoard Juqi, otherwise he would be severely punished, but it would still cause a lot of panic to the villagers, even if the grassroots organizations got the order at the same time, they also began to organize various forums to appease the people, but the people's turmoil is still inevitable......

It's just that there's no better way.

If we don't do our best to maintain stability now, we will really wait until the future when there is a shortage of materials and develops to the point where it is the same as in history, not to mention ordinary people and soldiers, even generals who want to eat some salt, they have to eat what kind of potassium salt from boiling grass and wood ashes, it will be too late to control it!

Although in the base areas, at least in terms of salt, this is not possible.

But Zhang Ran had to take precautions in advance in order to be prepared.

After arranging the affairs in the base area, Zhang Ran was ready to leave for the county seat, because he still had some things and wanted to explain to Gao Jin and the others.

Before he left, Han Jinshan had already come, his face was pale, and his whole body was trembling slightly.

Zhang Ran's heart tightened, and he hurriedly closed the door before lowering his voice and asking, "What's the matter?" ”

"Last night, I injected penicillin into a couple of seriously injured people who were too badly injured!"

Han Jinshan said with tears in his eyes: "All dead...... I don't know if it was because of the penicillin problem or because they were so badly injured that they had stretched their limits......"

"Don't panic!"

Zhang Ran patted Han Jinshan's shoulder fiercely and calmed him down before saying: "The matter of penicillin, only you know, as long as you don't say it, no one will know-besides, I have seen the seriously injured people you mentioned, if there is no special medicine to control inflammation as soon as possible, they will all die sooner or later......

You're really trying to save them, aren't you? ”

When Han Jinshan heard this, his expression looked a little better, and he crossed his fingers and analyzed: "According to what you said the captain, I did the skin test, it shouldn't be a problem of allergies...... I've done my best in purification, and if it's really because of the death caused by the lack of pure penicillin, then I suspect that it is impossible for our detachment to make usable penicillin......"

"Could it be a dosage issue?" Zhang Ran asked.

"I injected according to the dosage you said Captain!" Han Jinshan Road.

Zhang Ran patted his head in annoyance, he found that he had missed one of the most critical questions!

Because the detachment did not have qualified testing instruments, there was no way to test the unit quantity of penicillin after purification, so it could only be injected according to the unit quantity of the original penicillin in Zhang Ran's memory......

But the problem is that the method he taught Han Jinshan to cultivate penicillin bacteria, although it is a method of purifying penicillin by the soil method, this method was proposed after the penicillin process has been relatively mature, and compared with the original process of cultivating penicillin to prepare penicillin, it is actually a lot more advanced!

"Have you ever thought that maybe the quality of the penicillin we make is good enough, and the level of penicillin bacteria per unit is much higher than we expected?" Zhang Ran said.

"This, unlikely, right?"

Han Jinshan never thought about this problem, after all, how rudimentary the conditions for preparing penicillin were on his side, and he, the chief experimenter, simply knew it!

He may believe that the number of units of penicillin bacteria prepared is not enough, but this is more than expected, how can he dare to believe it?

But Zhang Ran is becoming more and more sure of his judgment!

It's not that he didn't suspect that the penicillin extraction process was not up to par, but that the injected penicillin was mixed with other fungi, which caused more serious side effects, and so on......

He was suspicious, just pretending not to know!

Because Han Jinshan has already said that in terms of purification, he has achieved the ultimate in what he can do, unless the detachment introduces more advanced equipment for preparing penicillin in the laboratory, it is impossible to do better!

That is to say, if Zhang Ran suspects that the preparation process of penicillin is not up to par, then, at least at this stage, the detachment can die of preparing penicillin by itself!

And this is something that Zhang Ran never wants to see!

Not to mention that there are more than 20 seriously injured people in the detachment headquarters, including Wang Wenping, who are in danger waiting for penicillin to save their lives, it is said that in the next few years, there will be a steady stream of seriously injured people waiting for penicillin to save their lives......

If the detachment couldn't get penicillin out, I don't know how many brave soldiers would die because of it!

Therefore, Zhang Ran would rather think on the bright side, and never want to believe that the detachment really can't get penicillin!

"Continue the experiment and halve the amount of injections from the amount used by those martyrs last night - no, reduce it to one-third first, and then increase or decrease it as appropriate after observing the situation!" Zhang Ran said.

"But if it's ......"

Without waiting for Han Jinshan to finish speaking, Zhang Ran interrupted him and said: "No case, take out the courage you have to cut off dozens of fingers of Yoshida Tada, Fujita Ichiro, and don't have any burden-because this is already the only way for Wang Wenping and their wounded!" ”

By the way, it can save Wang Wenping's life, but if it's wrong, it can make them suffer less!

Han Jinshan smiled bitterly when he heard this, and said in his heart, Captain, how can you compare those seriously injured soldiers with Yoshida Chung Fujita Ichiro and them?

Yoshida Tada, Ichiro Fujita, they are devils, in my eyes, they are not even as good as dogs, right? But these seriously wounded, they are the fighters of our detachment, they are wounded in heroic battles......

But thinking about Zhang Ran's words, Han Jinshan had to let go of his burden and give it a try, thinking with luck, what if?

Since Han Jinshan had already started the penicillin experiment, Zhang Ran had to go to the county seat immediately, and was ready to wait for the results.

I wanted to take a break, but my heart was full of all kinds of thoughts, I was worried that the penicillin experiment would not be successful, and I was worried about something else, so I didn't lie down in bed for half an hour, Zhang Ran got up again, and went around to the quilt factory that he hadn't been to since he came back.

Although it is only the middle of August, the quilt factory has already started its work in full swing to prepare winter clothes for the soldiers and militia.
