The start-up plan of the Starland mine was barely completed on the third day before the blood moon man arrived.

The full speed operation of the Arsenal on the earth and Mars bases ensures that the shell of the neutron mine is manufactured on time. Because of the physical properties of the neutron material, it cannot be produced in the normal assembly workshop. Under normal space conditions, the super specific gravity of the neutron material can not be held by any tool, such a small volume and such a huge specific gravity, It will pass through operating pliers, hands or anything trying to hold it, like a steel ball on the water.

In this way, the neutron mine can only be assembled in weightless space. Huang Myanmar Yang invented a complete set of magnetic levitation machinery, so that the decomposed neutron material is protected by a magnetic field from beginning to end. After entering the mine package and starting the magnetic shell, the manufacturing of a neutron mine is completed.

Hao Zhi floats in the manufacturing workshop and casually picks up a neutron mine from the shelf. It's small, just like the pinball he played when he was a child. The difference is that it's completely opaque, pure black, pinched between his fingers and doesn't feel any deterrent.

"It's so strange that such a small thing has the same power as the nuclear bomb explosion!" Hao Zhi couldn't help but praise the old sheep.

"In fact, the explosive power of nuclear bombs is smaller than that of ordinary nuclear bombs in this era. The explosive equivalent of a neutron mine is only equivalent to an atomic bomb of 500000 tons," said the old sheep calmly.

"That's quite OK. You know, the nuclear weapon that mankind put into the battlefield for the first time, that is, the 'little boy' that exploded in Hiroshima, Japan, has an equivalent of only 20000 tons! This small one is equivalent to 25 atomic bombs like that exploding at the same time. That's enough!"

"Hehe, mankind has been crazy about developing weapons and equipment since the apocalyptic era, and is very obsessed with the manufacture of super powerful nuclear bombs. What we have witnessed is that the whole mankind is moving forward at full speed on the road of high-end weapons development, and we don't even have the brakes. If it weren't for the blood moon invasion, these weapons would have a place to play. I'm afraid with the weapons and self-confidence currently possessed by mankind, It's not sure what the inside looks like. Self destruction is almost inevitable! "The old sheep laughed.

"I wipe. According to your theory, the arrival of blood moon people may not be a bad thing?"

"Just from a certain point of view, human beings are a race obsessed with studying how to kill themselves. They are naturally a death maniac!" the old sheep took the neutron thunder in Hao Zhi's hand, put it back on the shelf, and then pulled the handrail around him to make his body spin 360 degrees in the air and fly out of the weightless workshop.

Hao Zhi followed closely like swimming. While the old sheep didn't look back, he suddenly picked up a neutron bullet from the shelf and put it into his pocket

This gadget is a good thing. It may come in handy in the future!

He was secretly happy, but he pretended to have a meaningless look. The two people slowly held the railing of the transition cabin to adjust their posture and keep their heads up. Then, the gravity of the transition cabin began to increase. Slowly, Hao Zhi felt the pressure from the soles of his feet, and he felt stepping on the ground again.

As he went out, Hao Zhi asked the old sheep, "how can so many Chinese bullets be put into the battlefield? You can't send small ships to release them one by one like transplanting rice seedlings. How can you ensure the distance and area of each Chinese bullet?"

The old sheep took off his radiation suit. He was a cautious man. Even if he entered the neutron mine production workshop for a short time, he still had to wear the radiation suit. Hao Zhi came to him today. On the surface, he was very curious about the neutron mine production process and wanted to visit. In fact, the purpose was to steal one he kept for fun, so he didn't wear it.

"Use bombs and blast them!" the old sheep pushed the glasses on his face with one finger. In fact, he is not short-sighted at all. In this era, people's biotechnology is so developed that myopia has long been a historical word.

However, as a scientist's old sheep, obsessed with the erudition of profound self-image, wearing a pair of glasses seems to be able to distinguish herself from other general scientists, and gradually becomes a habit to retain, as if some women are accustomed to using eye shadow to make their eyes look more attractive.

"Blasting?" Hao Zhi was surprised. "Wouldn't it be all blown up in that case? It's over if you can't control it well!"

"No..." the old sheep picked up a mushroom nail on the workbench, which he used to nail his work schedule on the wall. It was like a general pushpin, with a large semicircular nail cap and a sharp needle, "We have made a number of bombs similar to this shape, which are launched into the star region near Mars through intercontinental missiles, and neutron mines are densely covered on the nail cap of mushroom nails in an obtuse hemispherical shape. The impact force of explosion will make them evenly stressed and scattered into the star space, and the density will be very uniform, just like the dense stars and matter inside after the big bang The degree is the same, basically there will be no big deviation. "

"However, in this way, the initial speed of the explosion becomes the flight speed of the neutron mine. These things will continue to spread without resistance, and the density is getting thinner and thinner, so that the enemy's warships can directly drill through it!"

"Hey, you're right, but for such a large space, their diffusion speed is relatively slow. Have you ever thought that most neutron mines may not be touched and explode at all. It's easier for us to release them. How to recover them after the war?

If such a dense minefield cannot be recovered and cleaned up, mankind's channel in this direction will basically be abandoned for outer space after the World War II, which obviously does not use future interstellar development.

This method solves the problem of recovery, because almost all neutron mines will fly towards outer space at a speed of more than 100 kilometers per hour, far away from the earth and expand more and more. Less than half of them will sense the huge gravity of Jupiter and fall to Jupiter and destroy themselves 20 years later. If they do not encounter large mass objects, they will continue to fly out of the solar system. At that time, they will be finished It has become an extremely sparse network of mines.

In a positive sense, once a massive object approaches the solar system, it will be ambushed and hit, reminding humans on earth that there may be outer space invaders, which can also be regarded as a passive defense system.

"Ha, you should not call old sheep, but old fox. You can think of this way!" Hao Zhi laughed and patted Huang Mianyang on the back.

"Therefore, the initial speed is very important. If the explosion force is insufficient, it will not be able to defend the enemy in a large enough space. If the explosion force is too large, it will also cause the neutron bomb array to spread too fast, and the validity period of the defense network will be shortened. The enemy is likely to use the mine gap to invade the earth!" Huang Myanmar anode explained seriously to Hao Zhi.

"Well, according to your current planning speed, how long is the validity period of this neutron mine array?" Hao Zhi asked with concern.

"About five days. After the density reaches a certain defense effect, it can last for five days. After that, the enemy's warships can safely pass through the mine array at a certain equilibrium point. After all, the gravitational radius of each two adjacent neutron mines is limited. Beyond this density, there will be a gap."

"Oh..." Hao Zhi prayed, "I hope the blood moon people will speed up their attack and enter Mars as soon as possible, otherwise, our Starfleet will be under great pressure!"

With that, he patted the old sheep on the shoulder and walked out of the laboratory with him. The old sheep looked at Hao Zhi's back and suddenly shouted, "be careful, it's not fun!"

Ha, this honest old fox was found by him
