At noon the next day, the day after waking up from his dream, Roland received real good news.

The Ministry of Engineering and Construction have finally joined forces to complete the layout of the site and equipment required for the "Flight of the Sun" program.

Because in theory, 52 kilograms of spherical uranium 235 can reach the critical point, so the element purification is not the biggest threshold, Lucia has been busy so far, the Institute of high-energy physics has accumulated hundreds of kilograms of pure uranium.

But just stacking uranium-235 together does not give full play to the power of fission reactions, unless the amount of input is staggering.However, its safety and practicality will be greatly reduced, so it needs to be stimulated by specific configurations.

Another key point of the plan is the test explosion.

To know that theoretical calculation is one thing, making it is another.

From principle devices to actual products, it is almost impossible to want a success during this period.According to statistics, many of the weapons products developed by Roland for the First Army have failed in the double digits during testing, which is still a case of reliable drawings and witch assistance.

The "Flight of the Sun" plan is undoubtedly more special.

Other weapons manufacturing, improvement, and testing can be carried out in one place, but the fission reaction does not work.Whether the result is success or failure, there will be a place that becomes a forbidden area.

In fact, it took nearly a month to visit the test site.

Although the fertile plain is vast, it can be used as the main direction for the future development of Winterless City, and it is obviously not suitable as a test explosion site.

There are many islands in the fjord, but the distance is too far, and now the pressure of shipping is very large, it is difficult to withdraw ships to transport all kinds of equipment.

The uninhabited desert in the south seems to be the most suitable location, but considering that there were a large number of "sticky people" there, in order to develop and use it in the future, Roland hesitated for a long time or vetoed the extreme south.

The test site was eventually set up west of the snow-capped mountains, the former Devil's outpost camp.

Although it is possible to encounter evil beasts and demons there, the risk is still within the scope, and no matter the success of the test after the explosion will form a polluted area, but will increase the safety of the back of Winter City.

After these two thresholds have crossed, they can be considered qualified for nuclear testing.

“Son, please take me with you."

"And me!"

"I won't say, as long as it's a weapon that can kill the devil, I'll teach it anyway!""

“Uh...” At the same time as the news was received, Roland also received a request for dialogue from the third border town.Looking at the three "big faces" squeezed across the light curtain, he couldn't help but wipe his sweat, "This is just a principle device test, and it is still far from the real weapon test."

Since he had instilled in the Tachira Witch the concept of "the glow of the sun", Pasha and Celine had been fond of it, but he did not expect that even Eli would join in, and there seemed to be a hint of piety in his tone.

“If it’s as good as you say it’s enough to light up the clouds above the human head, then I hope to see it born all the way.”Pasha lowered the Lord’s need.

"I also made a lot of efforts to make the core components of the sun, and you can't let the participants of the plan stay here?"Seren added.

“But from the snow-capped mountains to the test observation point, there is no passage...”

"Don't worry, there is no sun in the evil moon, and we will have a lot more time outside than usual."Eli quickly replied, as if afraid that he would say nothing, "and the last time Fleur drilled out the passage was still there, we would never attract anyone's attention when we left the city.""

Roland looked at Anna with a smile, and the latter nodded to him with a smile.

Since the three of them have said this point, it seems a little inhuman to disagree.

"Then I will let the Ministry of Construction leave your seat in the bunker, remember to take part of the god to punish the witch, and pay attention to safety on the way."

“Thank you, Your Majesty!”The three are happy.

Looking at this scene, Roland was a little embarrassed.

In previous lives, this weapon was often seen as an opportunity for self-destruction, with numerous literary works and biographies describing it as the sword of Damocles hanging over the head of a human being.But here it is the dawn of hope – when darkness comes, only strength can shelter civilization and thorns.

He looked at Anna, "Let's go too."

...

Fifty kilometers north of the snow mountain.

The snow here is much larger than the winter city, not only covering the land that has been corrupted by the devil, but also makes the bunker project extremely difficult.

Fortunately, with the help of the powerful and endless god-punishable witches, the construction team finally took root in this place where no one smoked.

In order to ensure the quality of the project, the workers in the team are from the elite of the Northern Expedition, and after experiencing the bloody fighting on the fertile soil plain, the bad weather can not be regarded as the most severe enemy.Moreover, they had been informed before departure that the construction project was the top secret of Winterfell, related to the future of the homeland and the kingdom, and the high remuneration issued by the Executive Office, so everyone was able to make up their efforts.

In the old gray castle, even if the nobles were forced, it was impossible for their men to open up a camp in such a place.

It took Roland and his party nearly two days to arrive at the test explosion, and after drilling into the command post half buried underground, the house was another scene - the thick brick walls blocked the wind and snow, the burning fireplace was claming, and the project leaders held up oil lamps and checked their tasks against the form, which seemed very busy.

Seeing his arrival, everyone's movements were so far as to salute, "See your majesty!"

“You continue to be busy.”Roland waved his hand, then looked at Karl van Burt, “What’s the situation here?”

“No trace of the devil has been found in the last month,” Karl replied, “and they should have abandoned the place altogether.”As for the evil beast, you can occasionally see so many dozens, which poses no threat to the garrison.Test blast stations and simulation equipment have been constructed and, if you have no other instructions, they are fully capable of meeting the requirements of the plan.”

“Where’s the test?”

"Thursday north, 15 miles from here."Carr pointed to the map and said, "You can't see it in the command post, the snow is too thick, even if it's three stories high, it will be blocked by snow."

"It doesn't matter, you'll see it when it blows up."Roland smiled and turned to Anna, "Then we'll start the first test."

In order to verify the feasibility, the two prepared at least three configurations for testing in half a year, this time the simplest gun configuration.
