The smooth production of isotope temperature difference batteries is not only good news for Chen Xin and scientific researchers, but also for this city, as well as the entire Hunan Province and even the Yan Kingdom.

This means that in this era, Yan Kingdom was the first to obtain the key to get rid of the energy constraints of the old era.

To put it more bluntly, the Yan Kingdom can not burn coal, but rely on nuclear power to meet the energy needs of this extreme cold end of the world.

In the field of nuclear power, the most widely used radioactive element is uranium ore. The energy generated by the fission of the isotope uranium-235, which naturally exists in nature, can be equivalent to the heat released by the combustion of 2,700 tons of standard coal.

Before the disaster, Yan Kingdom was one of the top ten uranium-producing countries in the world, with an annual output of more than 1,600 tons.

Uranium ore itself is also an element that is widely present in nature. Its content is higher than that of gold and silver. As long as you master the utilization of uranium, you will no longer have to worry about energy issues.

For Yan Country, having isotope temperature difference batteries means that they can completely generate two batteries in one shelter. In the next ten years, this shelter will no longer have to worry about energy issues.

Before the isotope in the battery is attenuated, the battery will provide sufficient electrical energy to the shelter.

To free the country's refuges from their dependence on coal, this means that for the country, it can free up all the manpower and material resources used to maintain coal transportation.

Railway transportation no longer requires most of its transportation capacity to maintain coal supply, and can transport more production materials.

The mining department does not have to burn the mined coal directly, but can be used in coal chemical industries such as coal oil replacement and coal gasification to produce more industrial raw materials and accelerate the recovery of industrial production.

It can be said that if coal for heating and power generation is no longer needed to provide shelters across the country, the post-disaster reconstruction speed of Yanguo can even double!

It is precisely because isotope temperature difference batteries have such important significance that the successful operation of the production line makes these scientific researchers so happy.

In order to celebrate this incident and to thank Chen Xin for his contribution to the construction and operation of this production line, the person in charge of the scientific researcher specially pulled Chen Xin and said that he would invite him to a meal to thank him.

Chen Xin refused, but this was indeed something worth celebrating, so he agreed.

Following the person in charge to a lounge, the person in charge took out a bottle of white wine and two cans, and got two portions of self-heating food. This was a big meal.

Looking at the things on the table, Chen Xin couldn't help but raise his eyebrows. If it was a disaster, these things could only be called a makeshift meal, but in this end of the world, these things are all good things.

There are two canned foods, one is lunch meat and the other is canned fish. There are no fancy advertisements on it, just a simple black label with the name and production information written. As for the production time, it was last month.

This is not the inventory before the disaster, but the newly produced one. Chen Xin understood this when he saw the production date on the can.

As for self-heating food and liquor, this is indeed the inventory before the disaster, because neither of them can be produced now because there is a lack of sufficient raw materials.

Now every grain of food is very precious. The main ingredient of the shelter food that survivors in the shelter can eat is the national reserve grain before the disaster, and the auxiliary ingredient is the mice and mushrooms raised by the shelter, plus the mealworms that have been made into protein powder.

Therefore, the country does not have excess grain to make wine, nor does it have excess grain to raise livestock. Therefore, the self-heating food with cumin and mutton on the packaging is obviously impossible to be something produced after the disaster.

Although according to the information Chen Xin learned, the country does retain biological samples in some places and raises some domestic livestock for meat such as pigs, cattle, and sheep, only the top leaders of the country and some people who enjoy special treatment.

If Chen Xin wanted to, he would be able to be treated with special treatment, but this was not very attractive to him.

Just as Chen Xin was looking at these things, the person in charge also found two cups, poured a glass of wine for Chen Xin, and opened the can on the table, poured water for self-heating food to heat it.

"I toast you this glass. Without your help from Mr. Chen, we would not have built such a production line no matter what! Thank you for your contribution to the country!" The person in charge held the cup and touched Chen Xin for a moment, and then killed the wine in the cup in one sip.

Seeing the excited look of the person in charge, I couldn't help but feel a little dazed and surprised. In his impression, the person in charge always looked very serious, usually serious, and rarely showed any expression.

However, as the alcohol was gone, the person in charge also opened up to Chen Xin: "To be honest, I actually envy those ancestors back then. Although their conditions were difficult, the people at that time were energetic. Although they lacked material conditions, they were rich in spirit!

They fought against the sky and the earth, and built our country today with infinite fighting spirit and pride. We younger generations envied us! The reason why I chose this job back then was that I hope to contribute to the country like my ancestors!"

"You can't say that. Are we also contributing to the country now?" Chen Xin could understand the thoughts of the person in charge. Although with the enrichment of material life, many people have become pursuing enjoyment, there are still such a group of people who are dedicating their youth and passion to the country.

"How can I compare with those ancestors? I have wasted most of my life. I just did such a trivial thing for the country." The person in charge's eyes were a little wet, and his emotions couldn't help but feel excited: "Speaking of this, I really want to thank you Mr. Chen. Thank you for giving me such an opportunity to contribute to the country! This is really an opportunity I have been looking forward to for half my life! Thank you!"

As he said that, the person in charge grabbed Chen Xin's hand and shook it twice.

Through the power of the palm, Chen Xin could feel the sincerity of the person in charge.

"You are serious. I have just done something within my ability. I am not worthy of your praise." Chen Xin was embarrassed by the person in charge and said modestly.

"Haha, Mr. Chen, you are modest! Perhaps it is someone like you who can better contribute to the country, right? I am still vain and always want to do something big, not satisfied with the work I do..." The person in charge shook his head, sighed and raised his glass again: "I won't say it anymore, in short, thank you, thank you for all this!"

As he said that, the two wine glasses met together.
