So don't even think about transporting raw materials from the outside world.

However, Lu Yuan has already had a countermeasure.

"Professor Sun, doctors, don't worry, listen to what I have to say!"

Lu Yuan said with a smile: "The matter of phosphate ore is estimated to be unsolvable for a while, and we can only let the Eighth Road side explore, but we can solve it on our side for sulfuric acid!" ”

As he spoke, he stretched out his hand and pointed to the low chimneys and said with a smile: "Professor Sun, as a chemical expert, extracting sulfuric acid from steel chimneys should be a trivial matter, right?" ”

"yes, how did we forget about that?"

As soon as he saw the chimney, not only Sun Xing, but even Dr. Wang slapped his head and screamed!

It is no secret that extracting various chemical raw materials from industrial waste gas is no secret in foreign countries, and people who have a little knowledge of chemical industry are very aware of it.

In the process of iron ore refining, the sulfur element in it will combine with air to form sulfur dioxide, and at the same time, sulfuric acid can be obtained by adding various solutions through wet hair reduction.

Lu Yuan didn't know much about this, but Sun Xing, as a chemical expert, knew a little bit, patted his chest and said: "Don't worry, head of the regiment, give me some time, let me transform this chimney, and there is no problem with purifying sulfuric acid!" ”

Purifying sulfuric acid is not only the output of an additional chemical raw material, but also has more benefits, such as the pollution of the atmosphere of dust, which can be solved to a certain extent, and at the same time, it can further reduce the emission of soot, so that the possibility of the steel plant being discovered by the Japanese reconnaissance aircraft is reduced again.

Of course, that's not all!

"Professor Sun, purify sulfuric acid here, try to separate ammonia from it, and try the furnace at the coke plant!"

Lu Yuandao: "I don't know where I've seen it, it is said that ammonia can be hydrolyzed to form ammonia, which can be processed into ammonia fertilizer, although the effect of ammonia fertilizer is not as good as urea, but for our current situation, it is better than nothing - as for the purified sulfuric acid to be put up first, if the Eighth Route Army finds phosphate rock, it can be used to make phosphate fertilizer, what do you say?" ”

"Yes, yes, yes......"

Professor Sun agreed in a loud voice, and then wondered: "The method of synthesizing ammonia fertilizer from ammonia, where did you see it, Captain Lu?" How come I haven't heard of it? ”ad_250_left();

"I forgot where I saw it, but I vaguely remembered it......"

Lu Yuan smiled dryly, and said in his heart that in this era, ammonia fertilizer has not yet appeared, where do I know where to see it? I can't tell you if I know!

"Hahaha, I knew that Regiment Leader Lu would definitely answer like this!"

Dr. Wang laughed and said: "Professor Sun, don't ask, the head of the regiment can't tell where you saw penicillin, but we just produced penicillin, and the effect is so good, the injuries of those seriously injured are getting better - as long as you do what the head of the regiment says, you will definitely be able to produce ammonia fertilizer, which will increase grain production, and we will have rice and white flour to eat every day!" ”

"That's ......"

Everyone laughed in unison, tacitly not asking more.

After all, Lu Yuan didn't want to say it, it was useless for them to ask, besides, everything Lu Yuan did was for the people on this side, and there was really nothing to blame.

"Captain, you're too boring!"

However, Wang Ma Pole, Big Dog Bear, Xu Yun, Mao Ying and others looked at Lu Yuan with a sad face: "It's just a threshing machine semi-automatic rifle, now you even know penicillin and chemical fertilizers...... How much else are you hiding from us? Can you tell it all at once and don't always surprise us, okay? ”

“……”

Lu Yuan rolled his eyes angrily, and said that he was just pretending to make some small invention to surprise you like this, if he frankly told you that he was a person who traveled back decades ago, wouldn't it scare you to death?

"Commander, can we make a request to you?"

At this moment, Dr. Wang came over with a look of expectation, and behind him, Sun Xing, Zou Leping, and others winked at him vigorously.

"Say, I can do it a long way, and I will never refuse!"

Lu Yuan said with a smile, these people are not only the saviors who may change the situation of the war, but also more likely to become their own God of Wealth in the future, what requirements do they have, what they can do and what they can't do, and they must also do it if they create conditions.

"In the Nanjing Massacre, so many compatriots died tragically at the hands of the Japanese army, and how many sisters were humiliated and died...... When we saw some reports, it was so painful that we wanted to eat the flesh of the little devils and drink their blood......"

Dr. Wang's eyes were red and he said, and it took a while to recover his emotions and said: "Later, we saw in the newspaper that the regiment commander actually locked up the imperial family of the Japanese army's senior general and lieutenant general in Muma County, and let them go to the coal kiln for labor reform, and beat them if they were disobedient...... It's enjoyable, it's relieving - we just want to see ......"

"I don't think you want to go and see it, but you also want to slap them in the mouth and kick them a few times to relieve their anger, right?" Wang Ma Pole laughed strangely.

Dr. Wang and the others laughed embarrassedly: "Isn't it a bit inferior?" After all, we people can't pick up our shoulders and can't lift them, let alone go to the battlefield to fight with devils, maybe we'll faint when we see blood......"

"What's next? The little devils killed so many unarmed people, even babies and pregnant women, why didn't they feel like they were doing it? ”

The big bear slapped Dr. Wang's shoulder fiercely, almost breaking up Dr. Wang's old bones, and said arrogantly: "Go, I'll lead the way for you, you can beat whoever you want, don't give me face...... But don't hit the vital points, and don't fight to the death, it's cheaper to kill these bastards like this......"

"I'll point you out, it's not interesting to fight those small roles, if you want to beat the big one, then the boring and untreated official is the biggest, the general, the commander of the Kwantung Army!"

Wang Ma Gong Xu Yun suddenly laughed strangely, lest the world would not rush to take the lead, saying that he must carry forward this tradition, as long as there are intellectuals who come to take refuge in the future, he can enjoy the special treatment of this little devil general, lieutenant general, and the big mouth of the royal family.

"Good good ......"

Dr. Wang, Professor Sun and the others rubbed their hands excitedly, and it looked like a child finally getting his favorite toy.

"I can't imagine that these professors and doctors still have such a mischievous habit......" Mao Ying laughed dumbly.

"It's not a prank, the main thing is to hate it......"

Lu Yuandao, he thought of the monkey spirit Su Ya who died in Nanjing, the corpses of the city, the floating corpses of the river when he crossed the river, and the blood-red river......

He was sure that when those patriotic overseas Chinese saw the newspaper, they felt the heartache like a knife, and the outright hatred that even the bones and teeth were itching.
