Those who are familiar with nuclear explosions know that the lethality of nuclear explosions mainly comes from three aspects, one is light radiation, the second is shock waves, the third is early nuclear radiation, and there are also nuclear electromagnetic pulses and radioactive pollution.

Europa's atmosphere is so thin that it doesn't even appear as the iconic mushroom cloud, and it doesn't have the conditions to form a shock wave that sweeps through thousands of armies, and the lethality of the explosion is mainly concentrated in optical radiation and nuclear radiation.

Generally speaking, light radiation accounts for about 50% of the energy of a nuclear explosion, and on a star like Europa, which lacks an atmosphere, the shock wave that should have been the main beam has been weakened to almost nothing, and the power of nuclear radiation has also been greatly reduced because of the super resistance of alien creatures, so that the strongest means of killing a nuclear explosion has become light radiation!

Nuclear radiation actually has an effect, but it is not as immediate as light radiation.

The sudden nuclear explosion was a great deterrent to aliens, with the center of the explosion as the center, the anti-aircraft fire within a radius of hundreds of kilometers was empty, and it took a few seconds to resume after a pause.

Although the pause was only a few seconds, there were a lot of shells that landed on the ground, and more importantly, the first nuclear shells were included!

The defenders had expected the arrival of a large number of nuclear bombs, but they did not expect to come so quickly, as soon as the suspended anti-aircraft fire was resumed, another nuclear bomb fell more than a dozen kilometers away, followed by the third, the fourth......

The fleet fired nearly 100 nuclear bombs in the first round, and more than two-thirds of them landed, and the entire surface of Ganymede was full of dazzling light and expanding fireballs, and the ground was melted by high temperatures, slowly boiling and slowly flowing, and the ice was melted by high temperatures, turning into lakes of different sizes and boiling waters.

Not only were the buildings and positions on the surface destroyed by the nuclear explosion, but the shallow underground bunkers did not escape the ravages of the nuclear explosion, and the cavities under the shallow ice surface were the hardest hit areas of the nuclear explosion.

In just half a minute, more than 70 nuclear explosions occurred in succession, destroying a small half of Europa's back in one fell swoop, and most of the anti-aircraft fire was sparse.

Among them, there are factors such as the destruction of a large number of air defense positions by nuclear explosions, and the reasons why aliens retreat underground.

But not all aliens have retreated underground, and many continue to fight at the risk of being bombed.

To aliens, they are all heroes, but to humans, they are just stubborn enemies, and Gao Kai did not hesitate to order the fleet to launch a second wave of nuclear bombs.

Nuclear weapons don't make the difference between winning and losing a battle, but it can dramatically speed up the progress of a campaign!

The first round of nuclear explosions destroyed a large number of ground facilities, and the interception fire on the ground became weaker and weaker, and more and more shells were hit.

At such a juncture, Ye Han suddenly received an emergency communication from the resistance organization!

Ye Han was very strange, he didn't understand why the resistance group contacted him at this time, after the communication was connected to the Yaoshan, Zeng Rui appeared on the screen and said in a very helpless tone: "Chief, they want to talk to you directly!" ”

Ye Han was puzzled: "What's the matter?" ”

Zeng Rui just wanted to speak, a tall figure suddenly appeared behind Zeng Rui, and swept Zeng Rui aside with a big hand, and then the figure knelt on one knee, and an ugly face appeared on the screen: "Chief, it's me who wants to talk to you." ”

"Who are you?" A thought flashed through Ye Han's mind, which was converted into an electronic signal through the biochip and quickly conveyed to Lin Yi's hands.

Lin Yi immediately activated the face comparison system, and an ever-changing alien face immediately appeared on a small screen.

It is difficult for human eyes to distinguish the appearance of aliens, and this comparison system is specially used to help humans distinguish aliens.

The alien on the screen: "I'm not anyone......" said a sentence to the side.

The disgraced Zeng Rui returned to the screen and said depressedly and helplessly: "He is a translator, a translator of the resistance organization." ”

Ye Han nodded slightly: "What's the matter with you?" ”

The alien raised an arm and pointed off the screen: "I want you, we want you, stop bombing, now!" "His grammar is really painful, but the words are still clear, and the meaning is clear, but it is dry and has no tone, like a word by word record, and then mechanically put together.

Ye Han's face sank, and he said patiently: "There is no such thing in our agreement. ”

"You can't continue, we have to land!" Aliens say.

"The landing must be after the air strike." Ye Han said.

The alien suddenly became anxious, and said a lot of words in his mouth, Ye Han didn't understand a word, he simply reflected that Zeng Rui dragged it over and said a lot in alien language.

Zeng Rui sighed and said, "Chief, they hope that the fleet will not bomb Ganymede with nuclear bombs. ”

"Why?" Ye Han's brows were deeply locked, and he looked like he was digging into the roots.

The course of the campaign was at stake, and he had to ask the reason before he could decide whether to consider the Resistance's request.

Zeng Rui said: "I don't quite understand, it seems that the nuclear radiation left by the nuclear explosion is too strong, and I dare not land in the nuclear explosion area or something." ”

Hearing this, Ye Han finally understood a little: "You mean, artillery shells are okay, but nuclear bombs can't?" ”

The alien immediately nodded like a chick pecking rice.

Ye Han couldn't help crying and laughing for a while: "Zeng Rui, you reassure them that nuclear radiation is not as powerful as they thought." ”

Zeng Rui talked to the alien again, and then said helplessly: "He doesn't believe it, he said starship...... Even Europa had been hit by a nuclear bomb, and the radiation they left behind was particularly severe, and they didn't come with the kind of bugs that eat radioactive dust...... Well, anyway, it's the same as just now. ”

"He's still quite persistent?" Ye Han pouted and smiled, "You tell him that these two nuclear bombs are different, this one has no radiation." ”

The more reasonable the ultra-high technical structure, the more thorough the reaction of the nuclear charge, and the less radioactive material remains.

It is true that the early nuclear weapons of mankind will leave a large amount of radioactive materials, but with the progress of human technology, the technology of the five major nuclear countries has been very high-end, especially China, the United States and Russia, and the strong radioactive materials left by the nuclear explosion can be controlled between tens of grams and hundreds of grams, and even only a few grams in extreme cases!

If such a little radioactive material is dispersed within a radius of several kilometers, the level of radiation in the explosion zone must have increased, but it is far from the level of human and ghostly relief.

The most obvious example is the little devil, the Mi army released two atomic bombs, but no one saw the little devil give up those two cities, and he lived his life as he wanted.

Zeng Rui sighed: "I explained, he doesn't believe it." ”

Ye Han continued to pout: "If you don't believe it, forget it, you tell him, how the air attack is our business, according to the principle of reciprocity, we don't interfere with their command, and they can't interfere with how we fight, that's all." ”
