A team of more than 100 elite soldiers of the Eighth Route Army, protecting the prospecting team of more than 300 people, prospecting in the wilderness where there are no people, those prospecting equipment are some equipment seized from the devils and some equipment from the cottage, and a careful investigation of an area.

The reason why these people came here is entirely because of Li Yunfei's words, saying that there is a special ore here, and after finding it out and bringing it back, it can make a powerful weapon, which can completely let the devils get out of China, and even cripple their country.

So hundreds of people came, in fact, these are only one of the teams, and there are more than a dozen teams out to find ore at the same time. Of course, this operation is still in a state of secrecy, only a few dozen people leading the team know about it, and others only regard it as an ordinary mining and prospecting operation, just like digging coal, so many soldiers are still a little depressed.

However, they were finally disciplined and obeyed orders, and everyone also wanted to work hard to find out the things and unload this boring errand as soon as possible, thousands of people worked together, and Li Yunfei knew that there was a uranium mine with considerable reserves near Baolong Mountain, so after thousands of people were looking for it here, they quickly found some clues.

"Company commander, did you offend your boss during the meeting, we are all veterans of Tiger equipment, how could we be arranged to help mine in a place where birds don't?" A platoon commander who had an excellent relationship with the company commander couldn't help but complain after he was busy with things.

"Little rabbit cub, you know a ball, this mine is different, it is very important, it is said that we want to counterattack the devil's lair by relying on this mine!" After being complained about for a long time, the company commander finally revealed some news. In fact, he also knew a little about it, he just knew that this mission was very important, and it should be true that the legendary dragon team started it.

"Head, don't comfort yourself, it's very important to dig an ore, can this stone be thrown over and kill people!"

"Don't talk nonsense, why don't I ask the instructor to come and talk to you?"

"Don't, don't, I was wrong."

"It's good to know that it's wrong, it's right to do things well, this time it's for the dragon team, things are done well, maybe he will be happy with the old man, and he can reward our company with a few magic transformation tiger styles." The company commander also heard that in order to mobilize everyone's enthusiasm, the dragon team had promised that he would reward a group of demon tigers, otherwise he would be a little emotional if he was arranged to come over to mine for a first-line team.

The platoon commander was the first time he heard about the Demon Transformation Tiger Style, and his eyes suddenly lit up, in the Eighth Route Army, the number of Demon Transformation Tiger Styles was very small, and the preciousness was almost the same as that of airplanes, because in order to avoid the loss of weapons, they were basically handed over to the Sharpshooter Special Operations Team led by the members of the Dragon Group for use, and there were only twenty or thirty in total in the hands of ordinary troops, and most people had just heard of it and never seen it.

"Head, I'm the best marksman in the company, if there is a reward for that gun......"

"Of course, it's a reward for me!" A young soldier ran over excitedly and took over.

"Playing with mud while you go, with your shooting skills, you can only be considered second-rate."

"Huzi, look at you jubilant, but what's the good thing?"

"Head, I found the uranium mine, but I found it!"

"How can there be such a thing?"

"Yes, there is such a good thing, luck really can't stop the city wall, I didn't expect to set up a tent for those people in the col in front of me, and put it on the ore vein......" The tiger introduced the process of discovering the ore.

It was indeed an accident, I was ready to rest, but those engineering exploration personnel went to eat after they came back, and he was studious when he was bored, he would also learn those engineers to fiddle with those instruments, but he didn't expect to really find some reflections on the instruments, so he took the instruments to look around and successfully found the mining area.

"Brother Huzi, let's discuss it, if you really reward a good gun, let it be given to me, how about I introduce my beautiful sister to you?"

"While playing in the mud, I'm a fellow sweetheart." Huzi directly refuted it with a word.

"I don't know if it's really going to reward the Demon Change, so hurry up and report the news to the headquarters." The company commander was also very excited, he finally completed the task successfully, and he should be able to go to the front line to fight devils when he goes back!

It's just that what surprised them a little was that the reward was that there were several magic weapons, but they were not transferred to the front line, and they deliberately explained how important the task here was, which was much more important than going directly to the front line to fight devils, and it was necessary to protect the safety of the mining area and the refining plant under construction, and more than 10,000 people were transferred, and even two sharpshooter special operations teams came...... China's nuclear industry has also taken a solid first step out of nothing.

……

Speaking of being able to find uranium ore so quickly, it actually has a lot to do with the little devils. In fact, since the occupation of the Northeast, the little devil has been looking for various minerals, mainly oil and iron, and after learning about the fission reaction from the German allies the year before last, he has been looking for uranium ore for more than a year.

Since the successful nuclear fission test carried out by Germany in 38, Japan has also obtained some first-pass technology, and has also launched their own nuclear program, but they have not found uranium ore for a long time, but their prospecting equipment in the northeast was indeed captured by the Eighth Route Army, and it is very coincidental that Li Yunfei also knows that a uranium mining area is near Baolong Mountain, which was re-recovered last year, so he can carry out nuclear industry research so quickly.

If it is only based on the foundation of China, perhaps after another ten years of recuperation and vigorous development, it will be possible to carry out such a great project, but Li Yunfei is a plug-in at all, and there is a lot of ready-made knowledge and data, so the cost of building a nuclear bomb for China will be more than 99 percent less than the cost of the Manhattan Project in the United States.

Of course, even if it is such a low cost, it is quite difficult for Huaguo, which is now in the beginning of industry, but the high-level leaders of Yan'an heard that after getting this weapon, it can completely defeat Japanese militarism, and even allow the Chinese nation to take off and stand at the top of the world again, so they immediately held an emergency meeting and unanimously passed the 'take-off plan', even if they tighten their belts and live, they must get a nuclear bomb out at all costs.

So the take-off plan led by Li Yunfei was launched so smoothly, and it is really hard to calculate how much investment there is, and nearly a million people are contributing their own strength to this plan. It is said that the current Eighth Route Army already has its own port, and Japan and the United States have not yet torn their faces, so some bold American businessmen dare to transport things to break through the blockade of the Japanese army and come to sell things, as long as they provide sufficient prices, many equipment can still be bought. In fact, this is also offending the Japanese army in disguise, so a huge plan against the United States is unfolding......

Of course, some equipment can't be bought, because the current United States doesn't have its own, so it can only rely on itself and find a way to build it.

Li Yunfei also underestimated the ingenuity of the Chinese in this era, Li Yunfei only introduced the various basic data and general appearance of various equipment for purifying enriched uranium, especially centrifuges.

Unexpectedly, after more than two months of tinkering with the halfway monks, the group of halfway engineers got together and worked on it, and they really came up with a prototype, which was tested, although the production efficiency was very low, but as long as a few more processes were added, it could still meet the basic requirements of enriched uranium, and it could be used.

The appearance of this thing has allowed Li Yunfei to save a lot of brain cells, and since the first generation of centrifuges has been made, it can always be improved by tapping and tapping in the future.

Uranium ore has been successfully mined, and there are methods for purification, so there is only enough time, the atomic bomb is not a problem, in principle, a nuclear bomb can be made within a year, and of course the speed will be much faster in the future.

As for the carriers, in fact, the Harbin aircraft factory had already begun to be established last year, and although those equipment were second-rate things from the United States, the Soviet Union also sent some experts to help.

Of course, the Soviets are not in vain to help, they need the help of the Eighth Route Army to block the Kwantung Army of the devils, and now the Soviet Union has officially faced Germany with Germany, and the fight is very ferocious, like a meat grinder, thousands of people die every day, they need a safe Far East region as the rear.

Although the aircraft factory was able to produce only second-rate things, the Eighth Route Army did not dislike it at all, and when the first aircraft went off the production line, it still made a big celebration......

……

"Brother Li, there is a big celebration party tonight, is Big Brother really not going?" Xiao Chen, who returned from buying equipment from the United States, of course, came to report to Li Yunfei 'as soon as possible'.

"You go play, I won't go, by the way, I heard that your Meng Shujuan is also here, and she is studying at the newly established Harbin Women's University, maybe you should go and see her!"

"Brother Li, in fact, I just came back from there, and she also went to that celebration party." Xiao Chen finally didn't dare to deceive.

"You oblivion boy, go have some fun, don't bother me to study the formation." Li Yunfei waved his hand and said, Li Yunfei is really not interested in the celebration party or something, it is better to stay in the office, try those basic energy circuits, and make more formations.

In fact, there is another reason why I don't want to go, I don't know who to take, but I have three confidantes, no matter who I take, it will always make the other two a little sad, although Yumo and Yichun always regard themselves as secret lovers, and have always thought that Tang Jieshu's identity is worthy of Li Yunfei.

However, Tang Jieshu is also very ashamed, because she completely robbed the man who originally belonged to someone else, so she really had no face to rob the eldest sister's position, she has always regarded herself as a little sister, and she also knows that Li Yunfei may not stay in this world for a long time, so she doesn't want to embarrass Li Yunfei.
