"It's just a matter of hitting a few steel plates, leave it to me!"

Niu Da patted his chest and said!

"Screw bolts can be handled by our second workshop!"

Cheng Dongshan Xiao Sanyuan assured: "As for the reel shelf and the like, it is simpler, plus bearings, and there are those motorcycle steel rings brought back in the warehouse, although many of them are twisted, but Zhengyi should be able to use them - captain, don't say it, we understand, when the time comes, we will do a component dismantling, and the bolts can be removed as soon as they are unloaded, and they will never delay the ......"

"Leave it to me for the experiment, whether it's gunfire or shelling, I'll test it here!"

Mao Drill followed the opening, and Gai Heiliang hurriedly added: "I will put a few movable machine gun holes on the frame, close when not in use, and open it when I use it to shoot ......"

Seeing that he had just said the word soil tank, and everything else was arranged by a group of guys, Zhang Ran was very unaccustomed to it, and seriously reminded everyone to listen to what he said, don't be self-righteous!

In the end, this earthen tank is a confined space, not only to consider the weight, to be besieged by devils and defended, but also to consider the problem of sound insulation - after all, if anyone hides in a big bell, who puts a bomb on the big bell, then the ears can't stand it!

"Don't worry, I've thought about this, and we'll find a way to solve it during the experiment!"

Mao Zuan smiled, and then pulled Gai Heiliang to mutter, and Cheng Dongshan, Xiao Sanyuan, and Niu Da also opened their posture and spread out the drawings, writing and drawing, and doing it very professionally......

Zhang Ran stood there alone, very desolate, and only felt that this life was as lonely as snow......

I wanted to find fault and prove my presence, but when I saw those experimental prototype guns and machine guns, I waited for enough steel to be mass-produced, and I saw that batches of cartridge case molds were being finally optimized to prepare for self-made bullets......

Zhang Ran decisively gave up the idea of finding fault!

Otherwise, finding fault to prove that your sense of existence is not done, and then being chased by a group of people for steel and copper, it will really be a stone to shoot yourself in the foot!

Back in the detachment, a group of cooks were killing rabbits, in addition to eating, the remaining part should be pickled to make pickled rabbits for storage......

Zhang Ran's eyes lit up, and he felt that he had to remind these cooks - in this summer, pickling is not enough, it is easy to stink!

Then he saw the cooks take the salted rabbits into the drying room for quick dehydration......

In the hospital, there are still some wounded people in the hospital.

Some doctors and health team members are caring for the wounded and changing their dressings.

Han Jinshan is busy in the laboratory.

Seeing Zhang Ran, he excitedly asked him to observe the cultured cells through a microscope, and determined that one of the slightly blue cells was Penicillium.

Because he had already used the pus extracted from the wound of the wounded to culture and observed, those golden staphylobacterium were killed very quickly in front of the penicillin bacteria without exception, which shows the great effect of penicillin bacteria on wound inflammation, just as Zhang Ran said!

The question now is how to grow more penicillin bacteria per unit scale and purify them for wound treatment......

Seeing Han Jinshan's worshipful face, as if he was meeting a god's pious eyes, Zhang Ran found that he had nothing to continue to guide Han Jinshan.

What he can say, he has already said a long time ago, such as how to prepare the culture medium for penicillin bacteria, and how to use centrifugal force to isolate strains......

Zhang Ran encouraged a few words, knowing that as long as Han Jinshan tried and made a lot of mistakes, it was definitely only a matter of time before the penicillin bacteria were finally extracted and applied to clinical practice!

Even if it's not this year, it's estimated that next year will bear fruit!

Then the history of penicillin's use in medicine will still change because of him - at least two years earlier than the large-scale application of penicillin to the wounded with the Yankees' entry into the war!

But Zhang Ran still couldn't be happy - because he had nothing more to hand over to Han Jinshan!

I don't know when it started, everyone in the detachment has begun to perform their duties, even if they encounter any problems, they will try their best to solve them, and there will be no need for Zhang Ran to go up to find a way to do everything, or point fingers......

This kind of situation is what every leader dreams of.

It is also what Zhang Ran has hoped for the detachment to become countless times......

It's just that when all this really came, Zhang Ran was extremely disappointed, and he felt that he had begun to lose the meaning of existence......

It seems that without itself, the detachment can run smoothly and contribute its strength to this war in a steady stream!

"Brother Ran, are you unhappy?"

Deng Ying didn't know when he walked in, and said softly while placing a cup of tea in front of him.

"Nope!"

Zhang Ran smiled dryly, pointed to the crowd who were busy and said: "It's just that everyone is busy, and they can't help with anything, and they feel like they're useless......"

"Brother Ran, what are you talking about!"

Deng Ying comforted: "No matter how good a general is, not every battle needs to be on the front line - everyone is busy, that's because Brother Ran, you have a good command, and everyone is just performing their duties according to your arrangement!" ”

"That's what you think?" Zhang Ran asked.

Deng Ying nodded his chin fiercely and said seriously: "Not only me, everyone in our detachment thinks so, but also Commander Pu, as well as Long Xin, they all think this way - you haven't come back two days ago, and Long Xin said when I chatted with me that if it weren't for you, Brother Ran, the situation of the War of Resistance on our side might be several times worse than now!" ”

Ahem......

Zhang Ran coughed dryly twice, glared at Deng Ying angrily, and said, "Miss Deng, don't praise me like that—although I know that I am amazing, but if you praise me like this, I can still easily become proud!" ”

Deng Yingle's flowers and branches trembled.

Zhang Ran suddenly felt that Deng Ying was simply beautiful at the moment......

But when he thought of Deng Fang and thought that this guy would carry a kitchen knife to settle accounts with himself, Zhang Ran's little thief courage that had just risen was immediately strangled in the cradle......

"Captain, captain, urgent!"

At this moment, the liaison officer trotted in and said with an ugly face: "Commander Pingtongguan Huang, military commander Song has called, the strength of the Japanese army is now being transferred on a large scale, and the troops are directly pointing at Pingtongguan and the area of Dingzhou City!" ”

"Damn it!"

Zhang Ran slammed his fist on the table!

He knew that this day would come, but he really didn't want it to come now!

Although in the original history, Dingzhou City has long been taken by the Japanese army, and even Pingtongguan has fallen, and now, the little devil has not started this war until now, and it is already the result of the wheel of history being displaced because of his arrival!

But he was really unwilling!

Because if you give him more time, wait until Gao Jin comes back with the welding machine and other equipment he purchased!

When the detachment builds a few cannons and some earthen tank flamethrowers, then they can contribute more strength in the process of the devil's attack on Pingtongguan......

It's just that the little devil has launched this offensive now, so that these fantasies have all come to naught!

But even if it's not ready, since the little devil has already been launched, it is impossible for the detachment not to move!

"If you want to fight, then come on!"

Zhang Ran roared and immediately ordered: "Contact Deputy Captain Kang, Captain Wang, and the captains of the guerrillas, and let all the men and horses of my detachment immediately prepare for battle!" ”

At the same time, he asked the liaison officer to immediately send a report to Liu Shi, telling the other party that he was ready for battle and ready to participate in the battle at any time!

"This guy, when it comes to fighting, is more active than anyone else!"

Of course, Liu Qing also received the information of the devil's abnormal movement at the first time, and when he saw Zhang Ran's report, he snorted, and then continued to send a report to Yan'an, asking Yan'an to approve the war!

"What if the old chief doesn't approve it?" Pu Yuanzhong asked worriedly.

Liu Qing didn't speak, just clenched his fists!
