Meng Qingxiao asked Min Keyong privately: "What did you say to them, why were they so polite to me?" ”

"I didn't say anything, just say that you are the leader of the No. 1 world, you have published the New Mencius strategy, led the people of the No. 1 world to defeat the Eighth World Alliance, and let the Eighth World Alliance compensate a lot of materials in exchange for prisoners."

"And they believed it?"

"Don't look at their local science and technology, it seems that the technology is not developed, but their world started the evolution of the whole people much earlier than us." Min Ke said, "Once a world has a mirror spirit, their horizons will be much broader, and they will have a chance to understand what is happening in many parallel worlds, so they may have known about what you saved the world." ”

"How do you know these things?"

"Shui Xinyi told me, didn't she sit with me all the time, we talked a lot along the way."

The military soon achieved some results, the enemy constantly threw on the ground, a kind of microorganism that can absorb a large amount of nitrogen gas and produce a large amount of nitrite and a small amount of carbon dioxide, their growth cycle is extremely short, the ability to reproduce is extremely strong, and the inhaled nitrogen gas is mineralized and excreted in the body through a complex chemical reaction, in order to reduce the nitrogen content in the air.

That alien is dead, suffocating.

The doctors also achieved some results after dissecting him, these aliens, like earthlings, also need to breathe oxygen to survive, but they only need very little oxygen.

Nitrogen is also not toxic to them, but when the nitrogen content in the air is greater than 40%, it will hinder their breathing, causing simple hypoxic asphyxia, and the concentration of nitrogen on Earth is extremely high, and these aliens can cause sudden death if they are exposed to the Earth environment for a long time.

More secrets about the enemy's body are being discovered by scientists, which have already been introduced in the previous article and will not be repeated here.

The enemy's purpose is self-evident, they want to transform the environment of the earth and make it more suitable for them to survive, no wonder they directly launched a big war as soon as they came to the earth, and they didn't talk to humans at all, because this was a war of extermination, and there was no need for dialogue at all.

If they succeed in transforming the earth, it will undoubtedly be equally difficult for the earthlings to survive, so the relationship between the two sides is endless.

Now to the dismay of the military, the enemy's fighter shield is too strong, more than a week has passed, they have not captured a single fighter until now, if they cannot find the enemy's weak point, they want to win the battle, it is simply wishful thinking.

The leaders of the No. 58 world attached great importance to Meng Qingxiao, a military genius who had won wars in another world, and invited him to attend a military meeting together, and asked for his opinion very solemnly.

Meng Qingxiao thought for a while and said, "I don't know much about our world, I want to ask, what do people from other countries say about the war between our country and aliens?" ”

One police officer sighed: "All countries in the world have been asked for help, but they are still waiting and seeing." ”

"Don't they know that disaster is on the horizon for their world?"

"They naturally know, but as long as the enemy does not have the ability to destroy the entire planet in a short time, they will not be in a hurry." Another officer replied, "It is a good thing for them to weaken our power with the help of the enemy, as long as the final result is the victory of the earthlings." ”

"Well, I've got that." Meng Qingxiao sighed in his heart, and then continued to ask, "My second question is, what is the most powerful weapon in our country?" If you are embarrassed, you don't have to answer, I want to know, with your most powerful weapons, without considering your own losses, you can be sure that you will inflict heavy damage on the enemy? ”

"This is something that the whole world knows, there is nothing to keep secret, and we have developed a second generation of nuclear weapons," said one of the officers. ”

"Are there any neutron bombs?"

"No, this is still in the initial experimental stage, and it may take decades before the research and development is successful."

"In that case, I'm sorry, with the power of your current weapons, you can't inflict heavy damage on the enemy, and you'll have to find some other way to win by surprise."

"Sir has a trick, please give me advice."

"According to your anatomical data, these aliens, like many animals on Earth, can hear a very narrow range of sound frequencies, and mainly infrasound, this is their advantage, they only need to speak to cause great damage to earthlings, but it can also be their disadvantage, my suggestion is to concentrate on the development of sonic weapons, its cost is low, and the effect is fast."

The officer frowned, "Sonic weapons? ”

Meng Qingxiao said: "Well, I don't know if you understand, the various organs in our human body are actually emitting infrasound waves all the time, because its frequency is lower than our hearing frequency, so we can't hear, but if there are infrasound waves of the same frequency in our body in the outside world, then resonance will be formed, and this resonance will cause us to go insane, dizzy and nauseous, and even die quickly." ”

"The difference between infrasound and ultrasound is that it has a very long wavelength and travels very far, and in some places, the infrasound waves propagated by volcanic eruptions can even circle the earth several times, so I make a bold guess that these aliens don't need to develop radio technology on the ground at all, they can send sound far away just by talking normally, faster than we can talk on the phone."

"Of course, in terms of overall convenience, it is definitely not as good as radio, after all, the speed of sound is not as fast as the speed of light, and it cannot travel in a vacuum."

The officer continued, "But, what the gentleman says, I have heard only the bad side for us, how should we use such weapons against them?" ”

Meng Qingxiao further explained: "If their communication in the atmosphere is really not through radio, but through shouting, then you can develop reverse sound wave cancellation, so that you can cut off their voices and make them all mute." ”

"Because infrasonic waves are extremely penetrating, you can even develop infrasonic noise weapons and shake them into deafness, as long as you avoid the bands that are harmful to humans, you can be completely harmless to humans."

The officer said admiringly: "Thank you, sir, for your guidance, you have really opened a new window for me, and I will immediately go and assemble a group of experts to conduct research." ”

The officer strode away, and now the other officers were relieved together, Meng Qingxiao was curious: "Who was that just now?" ”

"He is the commander-in-chief of our three armed forces, the head of Li Zhengchao."

"Oh, no wonder, you don't even dare to breathe in front of him."

The officers immediately smiled bitterly.

Meng Qingxiao thought for a while and said: "I have seen a movie called "Earth Defense War" before, which is a very old movie, about a giant alien spaceship invading the earth, which is very similar to the situation we are facing now. ”

Min Keyong asked curiously, "Oh, how did the earthlings win in the end?" ”

"Those aliens have poor computer technology, and the earthlings snatched an alien spaceship, sneaked into the aliens' mothership, used the virus to close their protective shields, and then the humans used missiles to destroy them."

Min Keyong suddenly sneered: "Cut, this is too fake, can the code between different planets still be shared?" ”

"Movies, there will always be some little bugs, and that's how they are set." Meng Qingxiao smiled, "But this movie still has some reference significance for us, for example, we can't break through the enemy's protective shield from the outside now, if we can steal one of their flying machines unknowingly, and then disguise their people and enter their mothership, even if we don't use computer viruses, the use of hydrogen bombs is enough to destroy them, I don't believe they still have a protective shield inside." ”

"Well, that sounds a little more reliable." Min Ke smiled and said, "Guys, what do you think? ”

One officer laughed, "It's a really good idea, if we can develop a sonic weapon, I think we can do both." ”

Meng Qingxiao said: "Sonic technology is actually very simple, the reason is simple and easy to understand, as long as you have an airplane in this world, you must have seen the power of sound, you will definitely find a way to study sound, now you only need to spend a little more energy to get closer to the weapon, it should be very fast." ”

Because Meng Qingxiao captured one of the enemy's flying machines without much effort, Min Keyong felt that he should be able to do it, so when these officers of this world got together to study how to get an enemy fighter, Min Keyong volunteered that he could give it a try.

He didn't know how deep the water was, what Meng Qingxiao captured was not a fighter jet, but an engineering plane, although there were also weapons on it, but the weapon system was not advanced, and it was difficult to use it when Meng Qingxiao was attacked at close range.

Enemy fighters are shielded, and even their mutated peacocks have a hard time breaking through the shield.

Min Ke excitedly found a lone alien fighter, followed the lightning attack of Meng Qingxiao's example, and the fire phoenix grabbed the fighter's shield with one claw, as if grasping a slightly soft huge glass ball, and the claw slipped and caught it empty, and then the huge body hit the fighter.

This time it didn't live up to expectations, and successfully knocked the opponent's fighter to the ground, but the fire phoenix and Min Keyong also fell not lightly, especially Min Keyong, who almost didn't fall disabled.

When the fire phoenix landed, the body couldn't be contained, and involuntarily rolled, the fire phoenix was tied to the seat, and there was a seat belt on the seat, which could fix the driver not to fall off when flying at high speed.

At this moment, the seat belt became a nightmare for Min Ke, and it was tied to Min Ke and slammed into the wall by the huge body of the fire phoenix.

Bang...... Crash...... Along with people and birds, they were buried by the collapsed building.

The fire phoenix has a strong body, and it doesn't care about this impact at all, it shakes its body and stands up, but Min Ke's body strength is not so high, and after being hit, he was already fractured, and he was violently raised by the fire phoenix, and even shook his body, and immediately injured again.

At this moment, the fire phoenix didn't know that its owner had been injured, but it did its best, and immediately rushed towards the fighter again, and it was a crazy pecking at the fighter.

The pilot of the star in the fighter was also very depressed at the moment, although he was not hurt too much, but he fell from the sky violently, and he was also a little dizzy, and then before he could recover from it, the pecking of the fire phoenix came again.

The terrifying attack power of the fire phoenix is different from the enemy's death ray, which is a beam of energy, and the hit object will be shot through at most, but it will not be knocked away, nor will it produce the power of vibration.

Although the fire phoenix's attack is not as perverted as the energy beam, its power is huge, and every time it pecks, it has a real force of thousands of jun, and although the energy shield of the fighter can barely block it, it can't weaken the power of the shock.

So the driver was pecked by the fire phoenix for a while, and half of his whole body seemed to be scattered, all his internal organs were displaced, and he spit out a mouthful of blood, and soon his eyes were blood-red, and his mind became weaker and weaker, and finally passed out.
