Just when he finally miraculously passed through the slime-intertwined fire network of countless "ants" and finally included the "hive" into his sight......

That god-like giant insect suddenly opened its mouthparts!

As if the skull had been opened, the huge mouth turned out an incredible 180°, and the colorful poppy-like "uranium ore" in the mouth lit up in an instant.

Worst!

A huge sense of crisis exploded in Qin Feng's mind, and before the sensor made an alarm of radiation attack, almost without any hesitation, the second lieutenant quickly flicked the joystick, and the fighter rolled rapidly, and in an instant, it passed by the intense γ rays shot out by the giant insect!

It's dangerous......

Even if he was half a second slower, he would inevitably be vaporized into a wisp of smoke.

It turns out that this is the real purpose of those so-called "uranium ores......

These "ores" are nothing more than glands in the mouths of giant insects that emit death rays.

Wait, wait!

It is glands ...... There is uranium!

To be able to radiate such intense γ rays, the purity of these uranium must not be low......

So......

Can......

"David, ask Chen Mengyao!" As if a flash of inspiration, Qin Feng suddenly shouted at the walkie-talkie, "What is the critical mass of uranium?!" ”

"48.8 kg...... What's wrong? "What came out of the communicator was the voice of a beautiful girl.

Ignoring why he would react immediately in the channel that should have only been heard by the pilot in the first time he raised the question, Qin Feng, who was too subtle and got a reply, was reassured.

"No, nothing ......"

Indeed, there are no more problems......

He's found a way to destroy those "beehives" and even kill the giant insects directly!

To put it bluntly, it's actually quite simple......

It's the glands that detonate it—the glands that look like "ores".

Because there's high-purity uranium in there!

As long as...... Let it reach critical mass......

The so-called critical mass means that when uranium-235 reaches a certain mass, the density of the radioactive neutrons is enough for a fission reaction to occur.

This is the critical mass.

At the end of World War II, the atomic bomb "Boy" dropped by the United States on Japan was made using this principle:

The atomic bomb contained a spherical uranium block, which has a mass less than the critical mass, a neutron reflector layer on the outside, and a cylindrical uranium block.

When the tube is ignited and the ordinary explosive is detonated, the cylindrical uranium block is pushed into the tank and merged with the spherical uranium block as a whole, and the uranium block reaches a critical mass, producing a chain reaction that releases an incomparably huge amount of energy, and finally explodes.

Of course, there is also a structure......

That is, uranium-235 is divided into two halves, and then, driven by the explosion of ordinary explosives, it is closed in a short time at high speed. In this way, two pieces of uranium-235 that have not yet reached the critical mass exceed the critical mass of uranium-235 when closed.

And since the critical mass of uranium-235 is 48.8 kg in the absence of a reflective layer, what about in the presence of a reflective layer?

Since the reflective layer allows the outwardly escaping neutrons to be reflected back, the critical mass will definitely be greatly reduced! For example, the critical mass of uranium-235 is 16.9 kg under the cover of graphite of near-infinite thickness, and the critical mass of uranium-238 is 16.28 kg under the action of the reflective layer of uranium-238 with near-infinite thickness. This critical system, under a certain excitation, can cause a chain reaction to form a violent explosion.

So the answer is obvious!!

What I want to do now is to become an "ordinary explosive" to detonate an atomic bomb and a "reflex condition" to promote the criticality of uranium.

While relying on the Banshee's 7.7mm Grimm electromagnetic gun, the explosive strength of a single tracer may not reach this level, what if all the bullets were fired at the same point?

The explosion that stacks up should be enough anyway!!

The "banshee" shook off all kinds of handsome maneuvers, like a waddling butterfly, and performed a gorgeous dance in the air. Again and again, it swept through the insect's forelimbs covered with sharp barbs.

After all, I've seen the power of this pair of Death Scythes in my dreams, and if I still have to make the same mistake with the same weapon, I'm too sorry for my title of "Fall King".

Therefore, Qin Feng avoided all the obstacles and continued to approach the target......

1,000 meters, 800 meters, 600 meters......

Even if it has long been in range, it is necessary to get a little closer, a little closer......

After all, if he wanted to shoot all the bullets at the same point, although even from a distance, Qin Feng was confident that he could do this, but now, he couldn't withstand a little defeat, and no matter how he shot from a close distance, he had a better grasp.

What's more, the closer it gets, the more powerful the bullet will be......

500 meters, 400 meters, 300 meters......

Now, even without relying on instruments, the huge glands can be seen clearly with the naked eye......

But at this very moment!

As if aware of the danger coming, all the glands once again lit up at the same time!

Intense γ ray, about to be launched again!

At such a close distance, even a god can't let the fighter plane escape this deadly ray!

However, Qin Feng continued to approach ......

200 meters, 100 meters, 50 meters......

Closer, closer!

And the glands, too, are brighter!

Finally, at the same time that the glands finally reached their brightest!

Qin Feng also pressed the shooting button on the side of the joystick!

Tracer bullets reinforced by electromagnetism poured out like a rainstorm, flashing a dazzling trajectory in a very short distance!

With the fighter plane slamming its head, the "banshee" swept past the glands of the giant worm and flew into the sky again......

He did it!

As evidence, an earth-shattering loud bang erupted behind him, accompanied by the desperate wail of the giant worm!

But......

Wait a minute!

The time of firing, the time of γ ray firing, the angle at which the fighter approached, the angle at which the shot was fired...... All these data, which would have been lost at the slightest error, all of which had to be accurate to a few decimal places, he had calculated them......

But there was only one thing missing......

That's the intensity of the explosion, the difference between the speed of the "banshee" - he missed the moment to escape!

And at the cost, he immediately felt the scorching heat emitted by the "banshee" cockpit.

Because of the explosion of the air wave, it has caught up with the fighter plane in an instant at a very fast speed! The huge mushroom cloud, as if the sea had submerged the ants, instantly brought the fighters, along with those beehives, and the ground densely packed with "ants......

Devour them all!

"Don't-"

Chen Mengyao, who was high in the air, let out a heart-rending cry.
