Li Yan's strategy is indeed very good.

With the help of the sound transmission effect of the special sonar, the dialogue on Ye Yun's side could be clearly heard in the base coordination room, so the analysis of the protective shield by Piaohua Blood also entered the ears of Li Yan and Zhang Huashan.

Piao Huaxi's guess about the protective shield is basically correct, this protective shield was originally taken from the protection system of the alien warship planted on the earth from which black hole, but the alien battleship fell too much when it landed, even if it was pulled back to the imperial capital military region at that time to be studied by the national elite and even a group of American and Russian scientists, in the end, it didn't understand anything...... Not too broken, but powdered. According to the scientists' collation, the shape and size of this alien battleship can be roughly restored, and the final conclusion is that the length of this thing is at least 5,000 meters!

An alien warship five thousand meters long fell to the ground, and the largest broken parts were less than the size of a twenty-square-meter room.

The end result was the preventive restoration of the warship's shield, and the birth of a simplified version. In the next few years of testing, we have repeatedly tested the defense limit of this shield, and found that this thing is really durable, as long as the energy is enough, it is estimated that even nuclear bombs can defend against many (but this is not testable), anyway, at least one nuclear bomb cannot be broken.

Later, after a period of testing, everyone found that this thing is actually not able to prevent anything, at least it can be broken if it is penetrated by a laser. After that, everyone tried to find a way to weaken it again, but this simplified version seems to be the weakest limit, even if the materials and some circuits are reduced, it can still produce the same defense, unless the energy is reduced to replenish...... But that's not about the ability to protect itself.

In the end, a mad scientist in the United States worked out a weakened version that could not defend against too violent explosives. But idle firearms and weapons can still be guarded against. Then everyone began to test and explore in many aspects, but unfortunately the final conclusion is that although the protection of this thing has been reduced after the revision, the energy required is not small at all, that is, this thing is more chicken ribs, and the fart is not used.

However, this improvement has allowed everyone to test the fundamental ...... of the shield It doesn't have to be a consistently high energy source output to break it up. No, the chicken rib version can be broken by hitting the same point with several Barretas in succession, but the interval between every two bullets cannot exceed one second.

After a full ten years, scientists in the three countries could only conclude that the shield was the limit of current human technology, and that any improvement would only render it useless. In desperation, everyone can only go home with their research materials, lazily make one or two, and install one for places such as the White House, the Pentagon, and the Kremlin in Zhongnanhai...... Anyway, this thing is better than a normal bomb shelter anyway, once activated. Nuclear bombs can be defended. As for other ideas such as putting one on an aircraft carrier or something, the idea is very good, but if it really starts a war, this thing consumes too much energy, and the aircraft carrier is equipped with it, and it is estimated that it can last at most ten minutes before running out of power, but who has ever heard of a naval battle ending in ten minutes? Once this thing is activated, the cooldown is twenty-four, and there is no possibility of even trying to defend it with a splash screen.

…… Drifting flowers and blood learned. Actually, it's this version of the shield.

At that time, China, the United States, and Russia were shielded, and anyway, at least the mansion of the family was protected. Let's discuss it, let's not spread this thing, clean up and disperse. As a result, there are only three countries that have this kind of protective shield, and it is precisely because of this that Ye Yun did not hit this big nail in the Blue House of South Korea.

However, everyone overlooks one point, Russia is poor.

Russia is undoubtedly one of the world's largest arms exporters. For the sake of money, people even dare to sell nuclear bombs, what is there to be reluctant to do with such a protective shield? In the final analysis, this protective shield is actually useless except for building covers, and if someone spends a lot of money, it may not be able to sell.

Of course. This kind of thing is by no means something that anyone can buy if they want to, first of all, Russia's hostile countries must not be able to sell you, otherwise we will really hit your door and find such a thing outside the house, and we will not be able to explain it to the family, right? Secondly, this thing has to be expensive, before someone sold nuclear bombs involved three lines of hundreds of deaths, although this thing may not be as valuable as nuclear bombs, but it can prevent nuclear bombs, naturally it must not be too cheap.

So, the organization of the numbering institute inquired about this matter, and the person in charge at that time made it very clear that we were a worldwide implicit research institution, and we had interests with many countries, but the weapons and other technologies we were researching were likely to be dangerous. We researchers are not afraid of danger, but we can't affect the masses, right? So if we get such a shield, the Institute of Conservation will come second, and the key is to protect the civilian population, so that countries will not expel us from the country, and if you don't believe it, you can see our concerns if you look at Chernobyl.

This sounds very simple and reasonable, the Russian side is reasonable when it hears it, and doesn't our country also have a research institute that has forgotten what number it is to cooperate with the government? Selling to them isn't a bad thing either.

So the Russian side said that it was no problem to sell this thing, but this thing is a rarity......

Rareness, on behalf of its rarity, and its own value, the most important thing is to keep it secret. If you buy it and keep it secret, it can only be called a rarity in my hands, and it is spread everywhere, then this thing should be called a big road goods.

When the representative of the Numbering Institute heard it, did he still understand? Immediately say that we will sign a confidentiality agreement, and if you can find out that I am selling this to any other country, organization, or individual, you will expel my research institute branch in Russia, and you will be wanted all over the world. As for the price, it's easy to say, who of our two brothers will make a price with whom, which will not only satisfy your leader, but also ensure that your pocket can bulge out, brother......

As a result, the shield, codenamed "Blue Curtain" by three countries, was sold to an organization of the Numbering Institute.

Even in order to prove that they are selling good goods, the Russian military (a certain bigwig) specially arranged a test in a small country in Eastern Europe (a hostile country of Russia), so that the Numbering Institute can see that you can buy this thing without losing it, but it can prevent nuclear bombs.

This is the version that Li Yan said he had undergone a nuclear test.

However the organization of the numbering institute ...... Well, let's call it by its real name, [Verdict]. The Verdict is a large hidden institution with 23 numbered institutes around the world, 74 research bases and 6 large testing sites around the world. Its own financial and human resources are comparable to those of a small developed country.

Of course, this is information that is not known to the world at present, and even countries only know that there is such a numbered institute in their own country or in their neighbors, just like China's No. 3 Research Institute and South Korea's No. 6 Research Institute.

Back to the topic.

However, organizations like the Adjudication themselves value and understand science far beyond their time. Even if it can't be compared with X-Steam, it is definitely more than 50 years ahead of the world.

There was no way to get the [Blue Screen] before, because the wreckage of the alien battleship was found in China at that time, and it just so happened that the penetration of the ruling organization in China was extremely difficult, and there was no possibility of getting things out of the Imperial Capital Military Region, so it was purchased from Russia at a large price. Now that I have bought it back, on the one hand, I really plan to use it for the bases under the umbrella of various research institutes, and on the other hand. A large number of in-house scientists are also very keen on extraterrestrial technology, so it is natural to study it carefully.

In the end, their research naturally succeeded, of course, this success was only relative to the scientists of China, the United States and Russia, and even the ruling only barely extended the limit of the [Blue Screen] to forty-five seconds...... This is the result of 50 years of science and technology ahead of the world.

Therefore, this improved [Blue Curtain] shield is the version that is currently being attacked by Ye Yun.

Li Yan's plan is indeed good. The judgment does have a deep enough understanding of the player, even if it is the strength of people such as Lao Dai and Sifengyuan. Being able to quickly collect qi (killing intent energy) and then use the killing intent burst to release the special move is the foundation of a top powerhouse, but at the same time, the result of rapid gas gathering is that it is impossible to collect the killing intent energy again in the short term - unless it is accumulated enough to release the killing intent energy many times from the beginning - this is naturally a disadvantage, but in contrast, being able to use the super special move to damage the enemy in the fastest time is also the choice of high-level bloodline players, and everything has advantages and disadvantages.

Then according to Li Yan's plan. Even if these people were strong enough to limit every second of attack that fell on the shield, and the interval between each attack was no more than 1 second, they would definitely be panicked or surprised by the sudden unshattering of the shield, either way, if the opponent was negligent, the shield would buy time for the people in the base. This was the time when the attackers were just weakened (Li Yan's guess). At this time, all the scientists will be evacuated suddenly, and at least half of them will be sent out!

As for why Li Yan guessed that these people could only reach the limit state of the protective shield every second by using the special skill of killing intent explosion, this was the vision of him, the person in charge of the base, and when he installed the blue screen from this base, he had already learned the damage that the blue screen needed to withstand when it reached the limit state.

……

Li Yan and Zhang Huashan looked at everything on the screen with burning eyes, their fists clenched.

In fact, Li Yan's plan was not just to simply take advantage of their attacks to send everyone away, you need to know that this protective shield can't even penetrate the inside, that is, if you want to send people away, you have to remove the protective shield.

Li Yan did not tell Zhang Huashan that his real plan was to suddenly remove the protective shield when the attacker failed to attack and was frustrated, and then immediately send the person out. As a result, the abrupt removal of the Blue Curtain shield would not only cause the island to shake off guard, catching the intruders off guard, but also causing them to rush into the base with the thought that something would not happen inside.

As a result, Li Yan will definitely die, but after the scientists send him out, Li Yan's family can be vigorously compensated by the board of directors.

As for Zhang Huashan...... Do you really think that Li Yan doesn't hate this guy for bringing his daughter in and thus attracting the enemy? He deliberately let Zhang Huashan come to die with him.

Of course, all this was based on the premise that the enemy would not be able to break through the shield.

In fact, everyone on the island was indeed panicked, whether it was Lao Dai or Sifeng Yuan and others, they all felt that their confidence was shattered under the insistence of the protective shield.

The later this thing is destroyed, the more things that can happen inside, and anyway, there can be anything, and what happens when you rush in at the end can really only be left to fate...... Don't forget, there's a 'world-destroying calamity' in there, and if you go in half a minute late, the people in the house will activate it, and it will really kill everyone.

Not only that, but everyone's confidence in Floating Flower Blood also began to decrease sharply, and they couldn't help but wonder if his statement was correct, and whether the attack just now was useless.

I don't know if this kind of psychology has been produced by others.,Anyway, the guy who is using the dragon and tiger flurry is a little depressed.,Even if you try to restrain yourself from thinking about it.,'It's inevitable that his brain will drill into the idea of 'Is my set of hard work really useful?'

Killing intent erupts, you have to have killing intent before the outbreak, and don't seek killing intent after the outbreak, at least you have to have an indomitable determination to keep this power at the peak.

As soon as his heart was weakened, his strength naturally inevitably decreased, and the dark blue brilliance that had been diffused under the protective shield was originally shining, but in the blink of an eye, it began to fade at a speed visible to the naked eye.

"Focus!"

Seeing that the last few punches were finished with a rising dragon (controllable direction, uncontrollable whether to stop), Qian Tuo had just relaxed a little, and suddenly Ye Yun's roar came from his ears: "The strength is strengthened!" Artillery ready! ”

He subconsciously began to regain his fighting spirit, not because he believed in Ye Yun much, but mainly because Ye Yun's roar scared him.

In fact, the artillery and Ye Yun will not play in Ye Yun's own plan, but now that thirty seconds have passed, the protective shield has not been broken, and the artillery will naturally be able to handle it after the end of the sting.

As soon as his man took to the air, a compressed flame condensed into a hemisphere that could glide on the ground grazed the soles of his shoes, and with a sudden bounce in front of the shield, it hit the point that the four people in front of him had been attacking.

This is......

Ye Yun's secret hook! (To be continued......)
