Buzz.

Buzz.

The friction between the bomb and the ground.

The sound can be heard very loudly within 5 kilometers.

Even if it was 15 kilometers, far away on the coast, Qin Feng, who was in command of the battleship, heard some buzzing sounds of burrowing into the ground because of his good ear power.

But for others, the ear is not very good.

Naturally, it is inaudible.

However, some people will say, since the two sides have set up a posture, why is Qin Feng still 15 kilometers away?

Hehe.

For such a large warship and fighter plane open posture.

That must be far away.

"Hey, why do you feel that this little radish head is a little strong?" Swinburn listened to the sound of the drilling, and he did feel that the strength of the drilling was very strong.

Moreover, Swinburn also nicknamed the small ground-drilling bomb developed by Qin Feng as a small radish head.

Of course, no matter how small the bomb is, it can't be the size of a turnip.

It's just that their ground-penetrating bombs are relatively large, and in comparison, aren't they just small radish heads?

"Mr. Swinburn, it doesn't have to be loud to drill into the ground, but the power of the bullet is great! In fact, the current ground-drilling bombs are being developed closer to each other, and the quieter the sound, the better! That is to say, when drilling into the ground, if the sound is small, it will not be discovered, and it will be difficult for the rescuers to arrive at the first time! If you sneak attack, it's very useful! ”

Next to Swinburn was a tech-savvy man.

Of course, Swinburn, as a member of the War Department, is it a bit stupid for you to say that he doesn't understand these high-tech?

This is, people who don't understand high-tech can't be the boss?

Then the emperor will not be able to farm and strike iron.

This kind of person, as long as you can manage the people below, it is good.

The division of labor is different.

10 seconds passed quickly....

At the speed of most ground-penetrating bombs.

Drilling down about 15 meters per second....

In other words, 300 meters, it only takes 20 seconds.

Moreover, the ground-penetrating bomb must be drilled into the ground and completely devoid of kinetic energy before it explodes.

So you haven't heard an explosion for 10 seconds?

So at a speed of 30 meters per second?

Qin Feng's ground-piercing bomb? At least 150 meters down, right?

"Swinburn always takes the lead! It's been 10 seconds! This ground-penetrating bomb has not exploded yet, according to the speed of a normal ground-penetrating bomb! This burrowing bomb? At least 150 meters down! ”

One of Swinburn's subordinates said incredulously, and said, "Could it be their technology? Can you drill 150 meters into the ground? This is the world record held by our Western tigers in the past! ”

"Let's take a look!" Swinburn's face was also not good, and he spoke for a second or two.

The ground-penetrating bomb hadn't exploded yet.

How much more does this have to go down?

That's a few tens of meters again?

It can be said that this minute and second of time is completely something that the whole world is paying attention to, and it is also the embodiment of the effect of the ground-penetrating bomb developed by Qin Feng.

The so-called one minute on stage, ten years off the stage. This is a quote for the stage.

And in the laboratory for decades, test explosion for a few seconds, this is for scientific researchers.

Anyway, this minute and second of time is really worth more than 10,000 dollars.

"It's been 20 seconds!"

"It's been 20 seconds!"

"The ground-penetrating bomb developed by Qin Feng's Great Wall Company has not exploded yet!"

"Mr. Swinburn, I'm afraid I've already gone down 300 meters, right?"

"It's time to catch up with our hidden black technology drill!"

Under the tree in Swinburne, completely stunned.

It was an accident.

Has this technology been leaked?

How did they develop it too?

And if you can't hear the explosion anymore?

Then you have to go over 300 meters and come to 400 meters.

And 420 meters is the level of black technology that the big tiger in the West has taken out today.

"It hasn't exploded yet...."Swinburn's heart also began to be calm, could it be that the ground-penetrating bomb technology they were proud of was about to be surpassed?

Swinburn's heart suddenly panicked.

Never again feel like your empire's ground-penetrating bomb technology is unmatched.

The people of the top ten groups were also stunned in the conference room at the moment.

After all, it will explode later.

It's going to be a bang.

A lot of people are blindfolded.

Even though they were watching with a projector, the speaker would also make a screeching sound.

But they were blindfolded and blindfolded for more than twenty seconds?

That ground-penetrating bomb didn't explode?

"What the hell? In terms of speed? I'm afraid I've gone down nearly 400 meters, right? ”

"It hasn't exploded yet?"

"Qin Feng's weapons company, something that has been developed! It's terrifying! ”

The top ten groups panicked here.

And Swinburn always had a blue face.

"It's been 30 seconds!"

"It's been 30 seconds!"

"It's been thirty seconds!"

"Haven't they exploded yet?"

"Oh my God!"

"At a rate of 15 meters per second...... That's already 450 meters! ”

"It has completely surpassed the latest black technology developed by our Western tigers!"

Swinburn's chest began to heav.

He could never have imagined that this would be the case.

"Oba, why hasn't it exploded yet?" Sikong Xuanmei leaned on Qin Feng's arms and began to cover her ears, but after waiting for a long time, the ground-piercing bomb just didn't explode.

After all, after going deep underground.

The sound of the ground bomb and the ground rubbing is gradually inaudible.

"Wait a minute.... Wait a minute..... Don't be in a hurry just yet! Qin Feng smiled faintly, teased her three thousand green silks, and said, "Don't be afraid, but the sound of the explosion will not be very loud." ”

After all, there are so many deep underground.

The sound of an explosion?

How big can it be?

But Qin Feng knew that the little devil robot had told him that his ground-drilling bomb was faster than an ordinary ground-drilling bomb.

That is, an ordinary ground-penetrating projectile, 15 meters per second.

And Qin Feng's ground-penetrating bomb is 30 meters per second.

In other words, 900 meters have already been drilled.

And according to the speed of ordinary ground-penetrating bombs, they are only 450 meters away.

"Won't there be a big explosion? Then I won't be blindfolded! Sikong Xuanmei was also speechless, why hasn't it exploded yet, how many meters deep into the ground? It's not going to be a dumb fire, is it?

Sikong Xuanmei suddenly came to such an idea.

But she didn't say it.

I believe in my husband very much.

"We are at sea, if the ground-drilling bomb explodes later, there will not be much vibration, there is no need to prevent anything at all, just look at it with peace of mind!"

Qin Feng spoke for a moment.

The drill has been down for a full 40 seconds.

"It's been 40 seconds!"

"Haven't you exploded in 40 seconds?"

“Oh， my God！ that is way too crazy!！ ”

Swinburn's scientific and technological personnel have been accurately calculating the time when the bomb will land.

The timing is precise.

They're starting to get more incredible, too.
