Release that Witch

A week later, a strangely shaped vehicle slowly entered the test site.

It is the first crawler tractor manufactured by the Winter City Ministry of Industry based on the complete set of drawings and technical guidance provided by the Ashes Design Bureau. It is only the same as the test piece except that the chassis is the same. Surrounded by a thick armor panel, the vehicle looks like a moving square box.

After driving into the heart-breaking area, it stayed in front of the melting tower for about half an hour, then turned the front of the car and headed south along the original road.

About five kilometers or so, a wheeled truck came close and took all the people in the car, while the square box tractor was abandoned directly in the snow.

The people went all the way and returned to the winter city from Da Xueshan the next day.

Roland, who got the news, called them into the castle for the first time.

"How, did you encounter any surprises?"

"Please rest assured that everything is going very well." Felice smiled and presented a piece of stamp to him. "Axia quickly positioned the picture at the time, and we stayed shorter than expected."

"Because, because there are specific time points, this is not too difficult," Axia is somewhat shy. "I have less control over my ability than other sisters..."

"Okay, don't be humble."

"Yes, it is true..."

Roland received the seal and his look was still serious. He looked to Momo around him, "I am bothering you."

"No, you are heavy, kneel down." Momo stretched out his hand to cover the side of the eye, so as not to see the king's knees, and to show his ability. After a few moments, she let go and bowed to Roland. "The numbers and colors of everyone have not changed significantly, which is basically the same as when they started."

Until then, Roland was relieved and smiled. "It's hard work."

"You too." The witches echoed in unison.

"The living room is ready for meals. Chaos drinks are available in unlimited quantities. Let's fill the stomach first." Looking at the people who were delighted, he smiled and shook his head. As for the Tachira witch who is involved in the action, it is basically a frequent visitor to the dream world, and there is no need to give any extra reward.

The use of Axia's retrospective ability to closely observe the instantaneous changes in the role of weapons has always been the most reliant improvement of the engineering department. By adjusting the retrospective speed, you can clearly understand the trend of the state change of the target at every moment, and most of the problems and leaks can be seen at a glance.

However, as mentioned before, the sun's glow is different from other weapons, especially the dirty bombs that do not respond completely. Many substances emitting deadly radiation will remain on the scene, and if you rush into it, you will undoubtedly suffer huge amounts of radiation damage.

To this end, Roland put the first crawler tractor prototype into it and converted it into a radiation-proof vehicle. Its left and right rear sides and bottom plate were wrapped with multi-layer lead plates with gold foil and cymbals in the middle. With a thickness of up to ten centimeters, it has a high shielding effect on photons, electrons and neutron jets. The structural weight of the comprehensive protection is only supported by the steam engine driven by the Rubik's cube.

In addition, the interior of the vehicle is self-contained with oxygen, which is almost completely isolated from the outside world, avoiding the risk of radiation dust entering the vehicle from the ventilation passage. In order to observe the scene of the explosion, a huge lead-containing glass was placed in front of the car body, and the thickness reached an astonishing 30 centimeters.

Considering that the access to the test site may cause the track and armor to adhere to the contaminant, he also specifically requested that the vehicle be replaced immediately after the person was sent out of the most dangerous core area, and the former was directly abandoned in the snow.

It can be said that the security measures that Roland can think of are used, but even so, he still has difficulty laying aside.

Fortunately, the final result shows that this observation was finally a complete success.

After getting the first-hand information on the scene, Roland immediately started research with Anna and Celine.

......

Using the time stamp to repeatedly play back the scenes that were slowed down hundreds of times at the time, the defects of the No. 1 principle device gradually surfaced.

"Our explosives are too bad." Anna whispered.

"I also saw that the impact of the explosion did not seem to be smoothly transmitted to the 'guns'," said Celine. "Can you use batch detonation to improve this problem?"

"I am afraid that there is not much hope in a short period of time." Roland licked some sour eyes and watched the scene of the explosion in two days. He felt that the whole world had only blue and white.

Although he had long anticipated the problem of explosives, he did not expect it to be so obvious.

No winter city has been mass-produced with double-base smokeless gunpowder. Although it is not as powerful as the high explosives such as Hessian gold in energy and detonation speed, it is enough for the military. Even if the power is insufficient, it can be compensated by the quantity. However, when placed in the principle device, the trouble is revealed.

More than a thousand kilograms of explosives is by no means a point on the design. It is stacked as large as a safe. In order to allow the explosive energy to be transmitted to the uranium block, Roland has deliberately made a lens similar to a funnel, hoping to The impact is as close together as possible.

There is no problem with this idea. However, when the detonation has not yet reached this stage, the situation has already occurred. Because the total volume of the drug pack is too large, each point is simultaneously detonated, so that the shock waves generated by the front and rear explosives cancel each other a lot. This can be clearly seen from the retrospective slow motion. The shock waves that collide with each other cause the entire steel lens and even the outer casing to undergo severe deformation, which means that a large amount of energy acts outside the 'gun' and pushes The energy of the uranium block is naturally much less.

The next step is a chain reaction.

Insufficient pressure in the crucible causes the fission to quickly stop, and most of the uranium is vaporized at high temperatures, which also weakens the effect of the neutron source.

"You can only find a way from another way." Roland is a handkerchief. Without electronic control technology, it is almost impossible to trigger all the explosives in a thousandth of a second, so that the front and rear shock waves overlap. Even if it is replaced by a high-explosive drug, it will only improve and cannot eradicate this problem.

He can let the Ministry of Chemicals try to study low-speed explosives and put them in front of the lens to minimize the interaction between the explosives. However, this process may require a lot of experiments to be deployed, and it can be successful. The most reliable practice today is obviously to compensate for the technical problems of detonation through configuration design.

"It seems that I have to work overtime this evening." He stretched out and said weakly.

"I will stay with you." Anna smiled. "How about rewarding a black fire massage?"

“Suddenly I feel full of energy,” Roland’s spirit spurred. “Is there any other reward?”

"What kind of?"

"Let me think about it... yes, how did the last mentioned..."

Is this also the knowledge from the dream world...

Celine used the Lord to cover the slightly hot face and quietly left the Lab on the North Slope.
