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

The Engineering Department and the Construction Department finally joined forces to complete the layout of the venues and equipment required for the "Sun Light" plan.

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

However, if uranium 235 is just accumulated together, the power of fission reaction cannot be fully exerted, unless the amount of investment is astonishingly large. However, in that case, its safety and practicality will be greatly reduced, so it needs to stimulate its energy efficiency through a specific configuration.

Another key point of the plan is to try out.

You should know that theoretical calculations are one thing, but doing them is another.

From principle devices to actual products, it is almost impossible to succeed in this period. According to statistics, the number of test failures of many weapon products developed by Roland for the First Army were above double digits, which was still with reliable drawings and witch assistance.

The "Sun Light" plan is undoubtedly more special.

Other weapons manufacturing, improvements, and testing can be carried out in one place, but the fission reaction cannot be done. Regardless of the result, a place will become a forbidden area.

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

Although the fertile soil plain is vast, it can be used as the main direction for Wudongcheng to explore in the future, and it is obviously not suitable as a test site.

There are many isolated islands in the fjords, but the distance is too far. Nowadays, the pressure of sea transportation is already very high, and it is difficult to withdraw ships to transport various equipment.

The unmanned desert in the south seems to be the most suitable place, but considering that there were a large number of "stickman" relics buried there, Roland hesitated for a long time and decided to the extreme southern border for future development and utilization.

The test explosion was eventually set to the west of the Great Snow Mountain - the former Devil Outpost Camp.

Although there may be evil beasts and devils there, the risk is still within the acceptance range. At the same time, no matter whether the test explosion is successful or failed, a polluted area will be formed, which will instead increase the safety level of the rear of Wu Winter City in disguise.

Only after these two thresholds are crossed can we be considered qualified for nuclear testing.

"Your Majesty, please bring me with you."

"And me!"

"I won't say anything. As long as it is a weapon that can kill the devil, I will learn it no matter what!"

"Uh..." While receiving the news, Roland also received a conversation request from the Third Border City. Looking at the three "big faces" squeezed over the light curtain, he couldn't help but feel sweaty, "This is just a principle device test, and it's still far from the real weapon test."

Since he instilled the concept of "the sunlight" into the Tachila witch, Pasha and Selene have been obsessed with it, but he did not expect that even Elxia would join in, and his tone seemed to have a hint of piety.

"If it is as good as you said, enough to illuminate the dark clouds above human heads, then I hope to witness its birth along the way." Pasha hung down his throne.

"I have also made a lot of efforts to manufacture the core components of Sunlight. You can't let the participants of the plan stay here, right?" Selin added.

"But there is no authentic tunnel to pass from Daxue Mountain to the experimental observation point..."

"Don't worry about this. The evil moon has no sun. We will spend a lot more time outside than usual." Elxia replied quickly, as if afraid that he would say something no, "And the passage that Fran crawled out last time is still there, and we will never attract anyone's attention when we leave the city."

Roland looked at Anna with a laugh and cry, who nodded at him with a smile.

Since all three of them have reached this point, it seems a bit inhumane if they disagree.

"Then I will let the Ministry of Construction leave your seat in the bunker. Remember to bring some of the God-Punishment Witches with you and pay attention to safety on the way."

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

Looking at this scene, Roland felt a little moved.

In previous lives, this weapon was often regarded as an opportunity for self-destruction, and countless literary works and biographies describe it as the sword of Damocles hanging above human heads. But here, it brings the dawn of hope - when darkness comes, only power can protect civilization and cut through the thorns.

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

...

Fifty kilometers northwest of the Great Snow Mountain.

The snow here is much bigger than Wudongcheng. It not only covers the land corroded by the devil, but also makes the bunker project extremely difficult.

Fortunately, the powerful and powerful witches helped the construction team finally took root in this uninhabited place.

In order to ensure the quality of the project, the workers in the team were all from the elite of the Northern Expedition Corps. After experiencing bloody battles on the fertile soil plains, the bad weather could no longer be regarded as the most severe enemy. Moreover, they had received a notice before they set off that this construction project is the highest secret of the Winter City, which is related to the future of the home and the kingdom. In addition, the high remuneration offered by the Executive Hall, everyone was very excited.

If it were the past grey castle, no matter how much the nobles forced them, they would never be able to open up a camp in such a place.

It took Roland and his group nearly two days to arrive at the test site. After entering the command post half buried underground, there was another scene in the room - thick brick walls blocking the wind and snow, the burning fireplace crackled, and the project leaders held oil lamps and checked their tasks in accordance with the table, looking extremely busy.

Seeing his arrival, everyone stopped their actions and saluted one after another, "Greetings to Your Majesty!"

"You guys keep busy." Roland waved his hand and then looked at Carl Vanbert. "How is the situation here?"

"There has not been found in the last month," Carl replied, "they should have completely abandoned this place. As for evil beasts, you can occasionally see dozens of them, which pose no threat to the garrison troops. The test bomb and simulation equipment have been built, and if you have no other instructions, they can fully meet the planned requirements."

"Where is the test bombing platform?"

"Fifteen kilometers from here to the north." Carl pointed to the map and said, "You can't see it in the command post. The snow here is too thick. Even if it is as high as three floors, it will be blocked by snow."

"It's okay, you can see it when it explodes." Roland smiled and turned to Anna, "Then let's start the first detonation test."

To verify the feasibility, the two men prepared at least three configurations for testing in half a year, and this time it was the simplest gun-style configuration.
Chapter completed!
