"In the next battle, maybe we won't be able to support it."

No matter how optimistic he is, Zhang Binhui still has to talk about the predicament in front of him.

"Even if there is no way, the decapitation must be carried out immediately. Lao Ha, let's go, take one step at a time, and hope to solve the problem of getting close to the mother worm at that time. ”

The Galactic Troopers and the Bone Troopers have each escaped into the water, each picking three targets, and then will act randomly.

The assassination operation is limited to five days, and whether it is successful or not, both teams must return before the next Europa tide. Because of the large-scale positional engagement, the expeditionary force could not do without the support of the warband.

After two months of ground combat on Europa, a lot of xenomorphs have been killed, so there are far fewer traces of xenomorphs below the ice.

After an hour of diving, the Galaxy team found no signs of xenomorph activity.

"Go to the 'volcano', the mother worm has limited mobility, there are no special circumstances, it will stay there all the time."

After a long period of fighting, Ling Doudou has matured a lot, and she is already a very good fighter.

According to previous markers, Team Galaxy lurked twenty kilometers from the volcano. Here, the traces of aliens can be seen everywhere, they surround the volcano, and it has become very difficult for Lingdoudou and her people to move forward.

"The biggest problem right now is that the mother worm is very sensitive to dark matter, and my Void Art relies heavily on dark matter.

If I don't use the Void Technique, I can't avoid the eyes and ears of the alien army, and I can't get close, how can I kill this female worm? ”

Zhang Binhui's divine sense transmitted, and the three of them fell into deep thought.

From time to time, aliens shuttle to and from the distant ridges, and they are constantly moving the radioactive materials they find into the "crater" to create an environment that the mother worm likes.

Staring at the work of the insects in a daze, Zhang Binhui's eyes became brighter and brighter, and a bold plan came to his mind.

"That way, maybe I can go and make a nuclear explosion."

hugged the two girls, Zhang Binhui told them his thoughts, Ling Doudou and Yuan Yuanzi were suddenly frightened.

"A nuclear explosion? You're crazy! How do you want to get it out? ”

Zhang Binhui explained: "The mother insect is not afraid of radiation, she needs to absorb a lot of energy from nature, so they always like to live in the crater.

Europa doesn't have a melted core, so the mother worm has to find another way.

You see, Europa, and now Europa, are constantly looking for radioactive material and then piling them together to form a small "volcano" to power the mother worm.

This "volcano" is actually a nuclear reactor in disguise.

When I was on Europa, I had already checked the substance found by the aliens, which was uranium-235, one of the standard atomic bomb charges, which was prone to chain reactions.

On our planet, mankind has a very mature experience in the use of nuclear weapons, and our atomic bomb is a weapon that uses the huge energy released by nuclear fission to have a lethal effect.

Nuclear reactors are just as good.

According to the nuclear fission chain reaction, we find a way to activate the reactor under the "volcano", as long as its neutron multiplication coefficient k is greater than 1, if it is not controlled, the scale of the chain reaction will become larger and larger, and eventually the "volcano" will definitely explode.

That is, the reactor can also become an "atomic bomb".

This is the case of what we often call a reactor supercritical accident.

The reactor weighs hundreds or thousands of tons, it is not very efficient and generally cannot be used as a weapon.

In this case, the utilization rate of fissile material is low, and the power of the explosion is not great. This is exactly what we need.

The atomic bomb has a role in promoting the evolution of the aliens, but if the mother worm is killed and the aliens lose their breeding weapons, what if they evolve?

Without backup, the bugs will eventually die, and victory will still belong to the human side.

What's more, if the aliens want to evolve, they can't be done overnight, and we still have time to destroy them before they can complete their evolution.

As long as all the mother worms are killed, the final victory will still be ours. ”

Zhang Binhui's explanation made the hearts of the two girls move: this is indeed the case, the female worm is the root of the alien, the real magic weapon that they sweep across the universe, if the female worm can be killed, a little nuclear radiation is indeed acceptable.

"Then how do you detonate that 'volcano'?"

Zhang Binhui briefly introduced the principle of the atomic bomb:

"To detonate that 'reactor', you first have to reduce the critical mass and at the same time increase the power of the explosion.

This requires us to use a fast neutron fission system, and the charge must be a high concentration of fissile material, and at the same time, the charge is required to greatly exceed the critical mass so that the proliferation coefficient k is much greater than 1.

Ahem, I can't explain this thing clearly, in fact, the principle is very simple, just find a way to let the neutrons bombard those radioactive materials. ”

Ling Doudou nodded: "This is easy, many of the spirit weapons we carry can do it."

But the question is, can you control the consequences of detonating this volcano? Or how powerful it will be, can you predict it?

How do you run after the explosion? With the power of the atomic bomb, even on the planet Xiuzhen, it is a top-level weapon, and if you can't escape, I am against the implementation of this plan. ”

Ling Doudou said categorically, Yuan Yuanzi nodded again and again on the side, and Zhang Binhui was suddenly moved.

"It's okay, just change that artifact a little bit and make it into a timing device. I figured out how to sneak through below and put it inside the radioactive material.

Don't worry, I'll go back if there's a danger, and we'll think of another way. ”

Repeatedly assured the two girls that Lingdoudou and the others finally agreed to the plan. Holding the transformed spiritual weapon, Zhang Binhui dived towards the center of the earth.

With his previous experience, Zhang Binhui went even farther in this circle, and he dived nearly ten kilometers before judging the direction and cautiously retreating towards the bottom of the "volcano".

Nine kilometers away from the "volcano", Zhang Binhui slowly dived upward, he strengthened his divine defenses, he didn't know if the mother worm would find him again this time.

The first three kilometers were very calm, and the aliens also set up defenses underground, and hundreds of high-level commanders lurked here, they carefully guarded the surroundings, but they did not react to Zhang Binhui who passed through stealthily.

When it approached six kilometers, the intensity of the radiation in the ground skyrocketed, and a large number of rays bombarded down, causing great trouble to Zhang Binhui, who was in a state of nothingness.
