Chapter 840

In a few minutes.

Above the cave.

The light flashed.

"Boom.. "Puff"

A huge blue container crashed into the water.

The transmission direction of the transmission node is not up and down.

As long as the delivery node is placed on the top of the cave, the delivery items will appear wherever they want.

The door of the container is open, and water keeps pouring in. Soon, the container sinks, and a dark current and bubbles are rolled up where it falls. If people are on it, they will definitely be rolled down.

One hundred meters.

If it's in the air.

The fall time is four or five seconds.

But in the water, it dropped for more than half an hour.

Two meters from the ground, the container stops. Tang Qing's mind moves. Under the influence of invisible mental force, the ground bricks fly towards the container one after another.

Make sure there's no BRICs down there.

The container dropped slowly.

More than 30 centimeters into the mud.

The soldiers began to put the bricks in containers, and the submersible was recycled.

And Tang Qing.

It started to spin around.

He wants to help.

But not to help gather the BRICs.

It's just packaging and transportation. It's just one less process. Don't forget, he's a man with "space equipment". He has 1000 cubic meters. If he really wants to help pick up gold bricks, he can't use containers and soldiers.

He can do it by himself.

Just a few minutes ago when I was waiting for the container.

Tang Qing peeled off the thick mud below to see if there was any fish missing the net. When the mud more than one meter thick was peeled off, Tang Qing found a lot of broken gold as well as broken rubies.

It's not rough.

It's gold fragments.

This aroused Tang Qing's curiosity.

The Duke of Miyi should not be able to think about it. There are so many gold grains that have not been purified. If there are a lot of gold grains here, it means there is a gold mine in the upper reaches of the underground river.

As for here.

Tang Qing is not hopeful.

According to the mining conditions at that time.

It's impossible to mine gold ore from here. Even with the current technology, it's not easy to mine 100 meters deep unless... The water level here was not so high before.

Tang Qing's mind suddenly burst out such an idea.

"Tang Yi, lower the detector and draw the topographic map below the water surface." Tang Qing immediately ordered.

"Yes, commander."

Three minutes later.

The top of the cave is full again.

Drop a gyroscopic detector.

It's one meter long.

In the moment of falling.

The upper and lower ring devices begin to rotate, and the left and right sides of each ring device are a laser emitter. The principle is simple. It rotates continuously at high speed, and determines the underwater terrain through the reflected information.

The two ring devices above and below the detector use two lasers with different spectral frequencies.

A probe.

A confirmation.

But the scattering and refraction of water is too strong.

The maximum detection distance is only 400 meters, which is tens of times shorter than the detection distance on the ground. However, it is already strong against the sky, and the cost of the motherfucker is also against the sky.

RMB 160 million.

This is still the cost price.

It's more expensive than building a satellite. Fortunately, it not only detects underwater terrain, but also has nearly 10 kilometers of underwater mobile target exploration and positioning function. It can find submarines and fish schools.

Otherwise.

With so much money, Tang Qing would never let scientists build it.

Tang Qing, who made it, loves it.

This is also one of the reasons for Tang Qing's crazy money making, that is, with the passage of time, the scientists in the scientific research area have deeper and deeper scientific contact, and more and more powerful materials have been used.

The crazy growth of its R & D cost made Tang Qing want to tear up the budget when he saw it.

It's terrifying.

Scientific research.

Or the whole system, all kinds of scientific research at the same time.

I'm really burning money with a boiler.

It's just a bunch of them.

The detector slowly fell down at the speed of one meter per second. On Tang Qing's watch, a projected topographic map from the water surface was continuously generated. After more than a minute, the whole topographic map was generated.

The detector floats up automatically after work and is recovered by the soldiers on it.

Look at the projection in front of you.

Tang Qing found that his guess was not wrong. It was not filled with water before, because during the exploration, there was a wooden bridge from the top to the bottom in the distance, but the wooden bridge was decayed and only some traces could be seen.As the wooden bridge is still more than ten meters below the water surface, it has not been found before.

Tang Qing found that there were two outlets in the underground river.

One is at the bottom, blocked by stones. It's obvious that there are artificial traces. Because they are huge gravel, they are not formed naturally, but they are not blocked tightly. The water is still flowing to the crevice.

The other is the current water outlet, which is almost flush with the water surface.

Tang Qing understood immediately.

The lower outlet used to be open.

Think of it.

Tang Qing floated past under the water.

Come to the water outlet.

Because of the high water pressure, there is a constant undercurrent around the gap. If you get close to it, you will definitely be sucked. However, the gap is very small. Even if you suck it, you can't suck Tang Qing.

"What if you break these stones away?" Tang Qing's desire for destruction began to rise.

Do as you think.

Tang Qing put her hand on a stone.

In less than a second, when the whole stone was covered by the nervous force, suddenly, the stone disappeared and Tang Qing took it into the ring.

After the stone disappeared, the original place was filled with water.

Then thousands of tiny bubbles come out from the original place. This is the phenomenon that the air in the water comes into contact with the vacuum environment. Ring collection is to collect all the particles in the area into space.

It looks interesting.

The stone just now is not a supporting point, so it does not cause any problems.

Tang Qing started the next one.

The next minute.

There are more and more bubbles floating up. Tang Qing once thought about using explosives, but he was afraid of something unexpected. He just wanted to move the stones that had been moved by others. Anyway, he was not in a hurry.

All of a sudden.

When Tang Qing moved away a big stone with a diameter of one meter.

The whole structure was destroyed.

Some of the stones in front of us began to move and vibrate.

At the same time, a huge thrust came from behind him. Tang Qing knew that the water was speeding up. Standing on the mouth of the water, he felt a lot of power. However, the resonance of the magnetic field was connected with the earth's magnetic field.

Want to push Tang Qing.

It depends on whether the force is stronger than the attraction of the nervous force and the earth's magnetic field.

It's a pity.

This kind of suction, which ordinary people can't resist at all, can't shake Tang Qing for the moment. Seeing the rock shaking more and more, Tang Qing doesn't have to stand here against the current.

Tang Qing ordered: "Tang Yi, let the soldiers begin to float."

"Yes, commander."

Finish.

Tang Qing walked 20 meters to the left, left the range of blocking rock, and stood on the edge of it, because there are still rocks to support, just in case, if it is accidentally involved.

Although I can't die, I can go back to the command room at any time, but it's a shame.

When all the soldiers come up.

Tang Qing began to collect rocks at the edge.

When the third stone weighing several tons is collected.

"Boom..."

The immediate plugging structure completely collapsed.

Under the great pressure, the stones rolled toward deeper places, and the water around them suddenly increased. After feeling it, Tang Qing still couldn't shake himself. He released his hand holding the rock.

I looked at the projection on my watch.

He saw that the water level of the pool was falling, but it was very slow. According to the calculation of the command room, it was estimated that it would take more than four hours to get dry. It was very slow. In four hours, it was time for Tang Qing to get up.

All of a sudden.

Where the stone is washed away.

Tang Qing saw something.

His expression was stunned.

How can there be tracks here?
