After careful calculations, ** are fixed, these things are simple to say, but it is quite difficult to do, like this kind of castle that can resist nuclear explosions, the location of the explosion is quite high, as for the amount of **, it is needless to say that it can be imagined, **more, it will cause a chain reaction, less, it does not work at all.

Finally, all the demolition experts stepped back, and now, just waiting for Wang Hao's order.

"Boom!" "Boom"......

Wang Hao didn't wait for anything, directly gave the blasting order, first after a series of small explosions, followed by you, a huge explosion resounded through the night sky, this blasting plan is a group of experts studied for a long time to come out, in order to let the large loading equipment enter the vault, it is necessary to blow up a large enough door, like this blasting is very difficult, first of all, they do not have any data on the thickness of the wall, it is completely based on estimation and prediction, if you use too much, it is very likely to destroy the entire castle, or collapse, the only way is to fix a range with drilling, blow up a loose space with a small amount of **, and then use a large number of ** to blow up the loose space, then, the scope of destruction is under control.

The amount of ** is very large, and the violent shock wave stirs up the air into smoke and dust, and the smoke is filled, and a huge sound is heard far away.

Some residents in the neighborhood had long been frightened by the fierce sound of artillery and gunfire and did not dare to come out of their homes, where the outside bombing was turned upside down, and many people thought that World War III had broken out and quickly hid in their cellars.

After the smoke and dust cleared, a huge, black hole hole was exposed in front of everyone, and several legion commanders did not act rashly, first arranged for a few skilled masters to inspect it with life detection equipment before letting the demolition experts enter.

It is true that there are many traps, but most of them have lost their effect under that round of indiscriminate bombardment, and after the electrical engineers checked again, some of the dangers of the remnants were also ruled out, but unfortunately, when they entered the hole, they did not see a mountain of gold bricks, but a wall of black steel.

Obviously, it was only the exterior walls that began to blow up, and the real line of defense was this steel cast wall, and there was a tall gate on the wall, which was so tightly bonded that if it were not for a seam, it would not be a door at all.

"Knock Knock ......"

A demolition specialist approached the dark wall and tapped it with his instrument, his face changing color.

"How?" Wang Hao felt the violent heartbeats of several blasting experts.

"This is composite armor, and if I'm guessing correctly, this should be depleted uranium armor." A demolition expert touched the dark wall and exclaimed: "Judging from the sound, this armor is at least three to five meters thick, and the outside is painted with black paint as a camouflage, if the entire building is this kind of composite armor, how much will it cost?" ”

Composite Armor ...... Wang Hao suddenly raised some information about composite armor in his mind, ordinary armor is made of a single material, such as steel armor, aluminum alloy armor, also known as homogeneous armor. As the penetration of anti-tank shells, missiles and rockets increases, homogeneous armor cannot withstand the attacks of such weapons. Continuing to increase the thickness of the armor can certainly improve the protection of the tank, but increasing the degree of armor will inevitably increase the weight of the tank and affect the mobility of the tank.

So, people came up with the idea of making multi-layer armor out of different ones, which is composite armor. Due to the different materials used, there are many kinds of composite armor, some of which are dual-purpose metals for internal and external use, with a layer of non-metallic materials sandwiched in between; Some are made of four or five layers of gold and non-metallic materials.

Some composite armor has a gap between the layers, which is called gap armor. Composite armor has multiple layers, and each layer of armor-piercing or armor-piercing shells consumes a certain amount of energy. Due to the different hardness of each layer of material, the core of the armor-piercing projectile or the metal jet of the armor-piercing projectile can change direction, or even break the core of the armor-piercing projectile. As a result, composite armor has a much higher resistance to penetration than homogeneous armor. When the weight per unit area of the armor is the same, the ability of composite armor to resist armor-piercing shells is twice as high as that of homogeneous steel armor.

"If there are really 8,000 tons of gold in this, it is worth the price that the American political axe spends on a lot, and what is a mere five-meter-thick composite armor for a country?" Wang Hao approached the wall, and True Qi followed the wall detection, and he could feel that the wall was at least five meters thick.

"Is there a way?" Sun Jian slammed his fist on the black wall, making a heavy echo, but there was no sign of shaking, what kind of strength did Sun Jian's fist have, his strength could not shake this wall in the slightest, which showed the strength of this composite armored wall.

"No, we don't have much ** now, the reinforced concrete wall has cost us a large part of our **, of course, this is not the key, the key is that our current ** can't blow up this wall, if you want to blow up this wall, it will take a long time, blasting involves mathematics, mechanics, physics, chemistry and material dynamics, engineering geology and other disciplines, our preparation is insufficient......"

"In other words, it's not that it can't be exploded, but that it takes time?" Wang Hao asked.

"Yes." An engineer who was cleaning up tools said: "The blasting work of composite armor like this is very tedious and time-consuming, if we want to open a hole that is enough for vehicles to enter, at least hundreds of small holes must be drilled in this wall to carry out directional blasting, in fact, we have enough ** now, the key is that it takes a lot of time to drill hundreds of small holes in this depleted uranium composite armor." ”

"For how long?"

"We don't have enough tools right now, and it takes at least five hours or more, which is still a conservative estimate."

"Five Hours ......"

Wang Hao's brows suddenly furrowed, obviously, five hours is impossible, if it takes five hours on the blasting, then, the time to carry the gold and retreat will be at least more than three hours, adding up to more than eight hours, this is simply unrealistic, here, it is dangerous to stay for one more minute, now, they are not facing an army, but a country, and more importantly, the current "Monk" can no longer be hit, one end of the US military found and carried out an air blockade, and the Monk Army did not retreat, The consequences were unimaginable.

"Boom ......"

While Wang Hao was thinking, several violent explosions were heard in the distance.

"What's wrong?" Wang Hao's face turned cold, and a pair of eyes shot into the air like sharp swords.

"Report to the general, two helicopters were destroyed." A soldier wearing a headset ran down from a military vehicle and reported that apparently, the police in a nearby city had noticed that something was going on here and sent two planes to investigate.

"Is there any other way?" Wang Hao nodded and said to a few demolition experts.

"No, at least, there is no way to force your way in, unless, we find the key to this door......"

"Keys?"

Wang Hao's eyes lit up suddenly, and his gaze fell on the huge door, only to see that above the dark gate, there was a keyhole every two meters, this kind of key was very cleverly designed, even if there were four keys, it was impossible for four people to enter.

Of course, another possibility is also ruled out, if there are one or two lock-picking masters, it is impossible to enter, unless, find four lock-picking masters at a time, but, in this world, it is almost impossible to find four lock-picking masters at a time, and are willing to risk their lives to rob this heavily guarded national gold reserve.

"Let me see."

Suddenly, Wang Hao's mobile phone rang with the immature voice of the little monk.

Wang Hao pointed the camera of his mobile phone at a few keyholes, and let the little monk observe carefully, perhaps, the little monk can find a way.

"Damn, grandma's, this is still a lock from the eighties, and there is no high-tech content at all." After the little monk saw it, he immediately scolded, if it was an electronic lock or some other lock related to high technology, he had a way to open it, but he had no way to open this purely physical lock.

"Is it complicated?" Wang Hao asked.

"How do I know if it's complicated or not, this is an ordinary door lock, and there is no password, but the size and craftsmanship of the keyhole should be very precise, if you want to use the true qi to open the lock, it is impossible, hehe...... "The little monk smiled strangely.

"Why?" Wang Hao was stunned for a moment, his thoughts were pierced by the little monk, he just wanted a few soldiers to use their true qi to open the locks.

"Just from the keyhole, it can be seen that although this lock has no electronic equipment and passwords, the manufacturing process of the lock is quite sophisticated, as long as there is the slightest error, it can't be opened, and the true qi is a kind of qi, even if it is well controlled, it is impossible to control the square rules of the key, so it is impossible to open it with the true qi, unless, you can wear four keys that are so precise that there is no slightest error, or kidnap the four people in charge of the key, otherwise, hehe......"
