"Professor Ding, how long do you think it will take to finish?" Yu Yifeng asked, he has a lot of work and heavy tasks, and it is impossible to wait here endlessly, although he is also very curious in his heart.

"It's hard to say, at this pace, it will take about five or six hours." Professor Ding Yidong said. "After that, we have to encapsulate the nuclear bomb and rocket, which we are not professional and leave to other laboratories to do. Finally, an ultrasonic test is performed. In total, it will take about two or three days. ”

Yu Yifeng thought for a while, picked up the design plan of the nuclear bomb and studied it carefully for a while, which recorded a large amount of data and all kinds of images, which was the thickness of a book, with his existing knowledge level, he could barely look at it and couldn't make any effective suggestions.

"Professor, you're too clever, aren't you? If it's too delicate, it's often not very reliable......"

"Alas, Captain Yu, you must know that the smaller the nuclear bomb, the more difficult it is. A big nuclear bomb is simple......"

Professor Ding Yidong smiled bitterly, "Time is limited, resources are limited, and I have no choice but to make that kind of 20-nanometer iron sheet paper." If you build a large nuclear bomb and have enough money, it will not be this structure. ”

Yu Yifeng nodded, "By the way, if the helium-3 nuclear bomb is completed and a nuclear test is required, some procedures still need to be followed, you know this, right?" Forehead...... Anyway, when it comes to my side, it's definitely fine, and I'll definitely approve it. ”

For these highly destructive and high-risk weapons, certain security procedures are still in place.

"Okay, I know that." Ding Yidong nodded and said, "I'll type the report tomorrow." Halfway through his words, he hesitated for a moment, and said slowly: "Captain Yu, if the blasting is successful, then my advance plan ......" He didn't continue, his eyes stared at Yu Yifeng, full of anticipation.

Yu Yifeng couldn't help but think of his "Billion Ton Helium-3 Nuclear Bomb Promotion Plan", and muttered in his heart, alas, this plan, how to say it, is too crazy...... He thought about the progress of the project again, and finally made up his mind.

"If the experiment is successful, we will definitely consider your plan again!"

"Then it's a deal!" Professor Ding said excitedly, "I have prepared that plan a long time ago, and I have revised it several times to ensure that it is foolproof!" ”

When he walked out of this laboratory, Yu Yifeng's mood was complicated. Although today's party was very effective and generally successful, there was another thing that weighed on his heart like a mountain.

That is - Noah's planned project did not meet expectations.

Half of the time has passed, and of the more than 100 projects, only half of them have met expectations, and the other half have not...... It's not that people are lazy, it's not that people don't work hard, it's that there is not enough energy!

Because of time, it is impossible to build more nuclear power plants. At present, the power plant is running at full capacity almost all the time, but it is still not enough.

Industrial production requires a large amount of electricity, especially the smelting of non-ferrous metals, which requires a large amount of energy.

Generally speaking, iron ore (Fe) and copper ore (Cu), which are weaker than carbon, can be reduced to metal elements as long as they are burned together with carbon (C), and they are basically produced from coal on the earth.

But on the moon there are no such things at all, only electrolysis can be used, and the electricity consumed is too great.

Yu Yifeng had a headache, there was no cable without copper, and there was no steel without iron, so the construction of the interior of the spacecraft was seriously lagging behind, and many ores were piled up, but there was not enough electricity to produce. It is said that it is difficult for a good woman to cook without rice, but with rice, there is no firewood, and it is not good.

Judging from today's report, the construction of various large-scale life-support systems has just begun, and it is too busy...... If all the spaceships are in the sky, but the things are not built, then the survival of everyone is not guaranteed.

So, we have to move a batch of energy from somewhere! It doesn't matter if you deduct a little or save a little, energy is the first key, which is a big mountain in his heart.

Yu Yifeng and Yuriko walked one after the other, both thinking about it.

Although the agricultural transformation plan has been successfully completed, it can free up a lot of energy, which is a good thing, but this batch of energy is expected, has been written into the plan, and many new projects need to use this energy.

Therefore, it is necessary to find a batch of unexpected energy sources to speed up the progress of the project.

So, where to find it?

Or, dismantle and turn the original base upside down, and a large amount of metal materials can be obtained. However, this is also a very large amount of work, and it must be done last. Otherwise, the spaceship has not been built, the base is light, where do people live.

The best way to do this is to cut the original hydrogen bomb manufacturing plan and replace it with a helium-3 nuclear bomb!

Because making a hydrogen bomb consumes too much energy, whether it is deuterium or tritium, it is troublesome to death. Although deuterium is present in water, it is troublesome to purify, requiring repeated distillation and then electrolysis, and each step consumes a lot of energy. And tritium will not even be able to expand production for a while, and can only be slowly generated in the reactor.

Most of the energy freed up by agricultural transformation is used to make hydrogen bombs. If you can, cut it all off and use it to smelt metal!

To make a helium-3 nuclear bomb, basically no energy is needed, helium-3, people have nearly 2,000 tons in their inventory, and they can be used directly! This is a very good way, Yu Yifeng can only secretly hope that Professor Ding Yidong's helium-3 nuclear bomb can be successfully developed.

……

Soon, three days passed, and Ding Yidong really lived up to expectations, and a report quietly appeared on Yu Yifeng's desk, which was "Application for a 1 Million Ton Helium-3 Nuclear Weapon Test"!

It's been developed! Yu Yifeng's mood was slightly excited, he flipped through a few pages, the basic content was similar to what he saw that day, and the safety audit procedures had also been passed, he waved his hand and immediately wrote down two words:

"Approved!"

The new government was very efficient, approving the test in the morning and conducting a nuclear test in the afternoon. After the notices were sent one after another, more than 100 people participated in the observation, including Yu Yifeng, Ding Yidong, Li Wu, and about 100 other scientific authorities, who came to estimate the blasting effect of the helium-3 nuclear bomb.

Everyone took this test very seriously, and if it succeeded, people would get a more powerful nuclear bomb. The way of nuclear propulsion will also be different, which is a nuclear test with a special meaning.

"I announce that mankind's first helium-3 nuclear weapon test has officially begun! The code name of this trial - Qiming! ”

As soon as the time came, Yu Yifeng read out.

"The estimated yield of this nuclear test is 1 million tons of TNT and the test site is the Ekre Crater. Observers are asked to be prepared. ”

The Acre crater is a no-man's-land 2,000 kilometers from the base, and there should be no problem with conducting a nuclear test here, and it will not affect the production of the base.

With a command, the helium-3 bomb was loaded into a huge steel container and transported by train and giant trailer from the factory to a 30-meter-high rocket launch tower about 100 kilometers outside the base.

"The launch vehicle is ready!"

"The observation satellite has been docked!"

"The observation force has arrived at its position!"

……

"All programs have been set up, please instruct!"

"Launch!" After Yu Yifeng solemnly announced, he pressed the nuclear button, and a ten-minute countdown appeared. This is a necessary safety measure, and during these ten minutes, the launch can be stopped at any time. Of course, if you want to send it urgently, you must have a sixty-four-digit nuclear password, which only Yu Yifeng knows.

Ten minutes...... Nine minutes, as the time counted down, everyone's hearts couldn't help but get nervous. Professor Ding Yidong is even more so, this nuclear bomb was cast by his own hard work for ten years, just like his own child, how can he not be nervous? His ten fingers clenched and loosened, pinched and released, and his heart was obviously very unsettled.

"Ten, nine, eight, seven...... Three, two, one, zero! "The missile took off with a bang!
