During World War II, the United States dropped two atomic bombs on Japan, and judging from the pictures, the United States just dropped the atomic bomb from the bomber, and a beautiful mushroom cloud rose over Japan dozens of seconds later, so can the atomic bomb be detonated just by dropping it directly?

Now that I think about it, that's not the case at all.

In fact, the structure of the atomic bomb is not complicated, simply put, it is divided into two structures, one is a container containing reactants, and then the outside of the container is an ordinary explosive, and the detonation principle is also very simple, that is, the shock wave generated by conventional explosives is used to promote the extrusion and expansion of the reactants of another device, and finally a chain reaction occurs, and the atomic bomb is detonated.

Generally, the reactants of atomic bombs use uranium-235 or plutonium-239, and if the purity of the reactants is not enough, the atomic bomb cannot be exploded.

In the case of super-large nuclear bombs, the nuclear weapon launch order generally has three ciphers, which are held by three people: the head of state, the minister of defense, and the chief of the general staff of the armed forces.

A minimum of two people is required to join forces to issue the launch order. The launch procedure adopts a dual-core button system, that is, each level has two sets of passwords and two keys, and only when the two sets of passwords are accurately put together and the keys are turned at the same time, the launch command can be communicated.

The location of the two nuclear missile launch keyholes is also specially designed, at least 3 meters away, to ensure that one person cannot insert two keys into the two nuclear missile launch keyholes at the same time.

Of course, there are exceptions, when the head of state travels on TV, you will find that the security agent next to the head of state will carry a leather suitcase in his hand, this box is the button for nuclear weapons, there are a total of 4 combination locks, which can be opened from both the upper and lower directions.

This nuclear button can directly designate the launch pad to launch nuclear weapons, but requires a password. This code was set by the head of state himself, and no second person knew it. It is a method that can only be used in particularly critical situations.

The suitcase nuclear bomb in front of me is designed for agents, but it is not something that ordinary agents can get.

In design, the Führer is similar in point, but not identical. He Zilong looked at it carefully, and finally determined that this was a suitcase nuclear bomb that would also be pressed at the same time and then timed to explode.

In other words, it is very difficult to detonate it with ordinary methods. Don't worry about hurting yourself by accident!

Come to think of it, you can't even launch a small nuclear bomb with a cannon, because the distance of the shell will detonate the nuclear bomb if you accidentally injure your own people. If this suitcase nuclear bomb is to be detonated, it will explode immediately on the spot, so the person who detonates it will not have time to run out of the explosion range, isn't this a suicide weapon?

Therefore, the detonation should be pressed in two places at the same time, and there are timer settings that can be set to 5 minutes to 20 minutes.

Looking at its size, it can probably affect a range of more than ten kilometers. In 20 minutes, even at the speed of a human being, it can run out of the area of influence, which is reasonable.

"In this way, this thing can be my big killer move, even in the face of thousands of horses, as long as I lead them into the explosion range, and then I run away, as long as I run a few kilometers more than them, even if the people behind me will also run over. As long as it can affect them a little bit on the edge of the explosion. Basically, if the whole army is wiped out, it can also make a military force of thousands of people immortal and severely disabled......" He Zilong touched his chin and suddenly had a crazy idea.

Thinking so, he closed the box. Remember the password to open the box, the hard metal on the outside of this suitcase should be used as a shield, and it seems that it can also be used as a shield in close combat, and it can be taken away at any time.

-

He Zilong, who has a plan in his heart and a bottom, is no longer afraid.

He began to carry his suitcase, took his weapon, and searched the fissure in the ground that he had thought of before, to see if he could find another entrance and exit in the direction of the land direction of the modern steamer in the lake.

Because, it could be one of the entrances and exits that can return to the original surface world at any time.

Finally, the hard work paid off.

Following the route of the new crack blown out by the earthquake, He Zilong searched all the way on the ground. Finally, at the entrance of a valley, one of the largest gaps was seen, leading to a large cave.

The entrance to the cave was small enough for a large steamer to enter and exit, and the entrance was huge.

Nearby is a valley with flowers and grass that seems to be different from the average place. He Zilong walked into the cave, and not long after, he saw the third thing that made him lose his mind today.

The first is a World War II ship in the lake, the second is a suitcase nuclear bomb, and the third is the thing in front of you.

A large bus, the modern kind, and, at first glance, it is not too old, it can even be said to be a product of the nineties.

"Wait, there's a voice in the bus, and there's a living person in it? Oh my God, it's Chinese, and English, and so on, and Japanese, it can't be the local natives of the underground world, it's a modern human ......" He Zilong suddenly heard some slight sounds coming from the car.

Then his whole being was blindfolded, as he heard the modern voice ring here.

As the saying goes, when a fellow sees a fellow, his eyes are full of tears. For a while, many complicated emotions echoed in He Zilong's heart, and he ran over a little impatiently.

It's just that before he got close to the bus, a figure flashed, and swayed and got out of the bus. There was even more "bang!", the glass of the bus was broken, someone was crawling out from the inside, and there was even the sound of children crying.

These people who wanted to get out of the bus, there were men and women, old and young, everyone climbed out of the bus in panic, obviously, the car seemed to have a problem.

Seeing that the people inside came out by themselves, He Zilong simply stood not far away and continued to observe. When I counted the number of people who got out of the bus, there were about twenty or thirty people, including men and women, old and young. After they got out of the bus, except for a few children who were disobedient and still crying, the others slowly calmed down, and then looked around, of course, they also saw He Zilong standing not far away.

"It's all modern people's clothes, and they really come from the outside world, but looking at their expressions, they don't seem to understand where they have been. Besides, how did this bus get to this world? It's so strange......" He Zilong muttered in his heart, a little incomprehensible.

But think about it, there is an entrance to the Dragon Triangle near here, and suddenly I feel that I can understand it again.

Maybe, maybe, probably, these modern people are the mysterious missing people who have disappeared near the Dragon Triangle again?

Are the new victims?

It's just that it seems that most of the missing ships and planes in the Dragon Triangle, and if there are passenger cars, will they also be missing?
