At noon the next day after waking up from the dream, Roland had a real piece of good news.

The Engineering Department and the Construction Department finally joined forces to complete the layout of the site and equipment required for the "Sunshine" project.

Since 52 kilograms of spherical uranium-235 can theoretically reach the critical level, elemental purification is not the biggest threshold, and Lucia has been busy so far, and hundreds of kilograms of pure uranium have been accumulated in the Institute of High Energy Physics.

But just stacking uranium-235 together won't give full play to the power of the fission reaction, unless the amount of input is staggering. However, in that case, its safety and usability will be greatly reduced, so it needs to be configured to stimulate its energy efficiency.

And another key point of the plan was the test explosion.

It's one thing to theoretically calculate, it's another to make it.

From the principle device to the actual product, it is almost impossible to succeed in 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, and this is still with reliable drawings and the assistance of witches.

The Sunburst program is undoubtedly a little more special.

Other weapons can be manufactured, improved, and tested in one place, but fission reactions are not. Regardless of whether the outcome is a success or a failure, there will be a place that becomes off-limits.

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

Although the Fertile Plain is vast, it can be used as the main direction of Neverwinter's future development, and it is obviously not suitable as a test site.

The fjords are so isolated and so far away that the pressure on shipping is already so high that it is difficult to spare 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 once a large number of "stickman" relics buried there, for the sake of future development and utilization, Roland hesitated for a long time and vetoed the extreme south.

The test site was eventually set west of the Great Snow Mountain, the former Devil's Outpost Camp.

Although it is possible to encounter evil beasts and demons there, the risk is still acceptable, and whether the test explosion succeeds or fails, a contaminated area will be formed, which will increase the security of the rear of Neverwinter in disguise.

Only when these two thresholds have been crossed can one be considered qualified for nuclear testing.

"Your Majesty, please take me. 」

"And me!"

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

At the same time that "uh...... received the message, Roland also received a request for dialogue from the Third Frontier City. 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 a real weapon test." ”

Pasha and Seline had been obsessed with it ever since he had instilled the concept of "Sunradiance" in the Tachira Witches, but he didn't expect Elfin to join in, and there seemed to be a hint of piety in his tone.

"If it's true enough to light up the clouds over humanity, as you say, then I hope to witness its birth all the way. Pasha lowered her beard.

"I've also worked the core components of Sunray, so you can't afford to keep the participants here, can you?" added Selene.

"But there is no tunnel from the Daisetsuzan to the test observation site......

"Don't worry, the Evil Moon doesn't have the sun, and we'll be out and about a lot more than usual. Elfin hastened back, as if afraid he would say a word, "And the passage that Fran drilled out last time is still there, and we will never attract anyone's attention when we leave the city. 」

Roland smiled and looked at Anna, who smiled and nodded at him.

Since the three of them have talked about this, it would be a little unkind to disagree.

"Then I will ask the Ministry of Construction to leave your seat in the bunker, remember to bring some of the Divine Punishment Witches with you, and pay attention to safety on the road. ”

"Thank you, Your Majesty!" said the three of them.

Looking at this scene, Roland was quite emotional.

In previous lives, this weapon was often seen as an opportunity for self-destruction, and countless literary works and biographies have portrayed it as a sword of Damocles hanging over the heads of mankind. But here, it is a glimmer of hope that when darkness comes, only power can shelter civilization and overcome obstacles.

He looked at Anna, "Let's go too." ”

......

Fifty kilometers northwest of the Great Snow Mountain.

The snow here is much heavier than that of Neverwinter, which not only covers the land that has been corrupted by the devil, but also makes bunker construction extremely difficult.

Fortunately, with the help of the powerful and infinite Divine Punishment Witch, the construction team finally took root in this uninhabited place.

In order to ensure the quality of the project, the workers in the team are all from the elite of the Northern Expeditionary Regiment, and after experiencing bloody battles on the fertile plains, the bad weather can no longer be regarded as the harshest enemy. What's more, they had been informed before they set off that this construction project was a top secret in Neverwinter, and that the future of their homeland and kingdom was at stake, and that the Executive Office had paid a lot of money, so everyone was working hard.

In the old Grey Castle, no matter how much the nobles persecuted, they would never be able to make their subordinates carve out a camp in such a place.

It took Roland and his party nearly two days to arrive at the test site, and after burrowing into the half-buried command post, the room was a different scene - thick brick walls blocked the wind and snow, the blazing fireplace crackled, and the project leaders held oil lamps and checked their tasks against the tables, looking extremely busy.

Seeing his arrival, everyone stopped moving, and then saluted, "Meet Your Majesty!"

"You guys keep busy. Roland waved his hand, then looked at Carl Van Burt, "What's going on here?"

"No sign of the devil has been found in the last month," Carr replied, "and they must have abandoned this place completely." As for the evil beasts, they can occasionally be seen so many dozens, and they pose no threat to the garrison army. Both the test bench and the simulator have been built, and if you don't have any other instructions, they will fully meet the planned requirements. ”

"Where's the test booth?"

"To the north, fifteen kilometers from here. Karl pointed to the map, "You can't see it in the command post, the snow here is so thick that even if it's three stories high, it's blocked by the snow." ”

"It's okay, you'll be able to see it when it blows up. Roland smiled, turned to Anna, and said, "Then let's start the first detonation test." ”

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