A few minutes later.

Above the cave.

The light flashed.

"Boom. Puff... ”

A huge blue shipping container slammed into the water.

There is no up or down direction for a teleportation node.

As long as you place the teleportation node on the top of the cave, the teleportation item will appear anywhere you want.

The door of the container was open, and the water kept pouring in, and soon, the container sank, and there was an undercurrent and bubbles rolling up in the place where it fell, and if people were on it, they would definitely be swept down.

One hundred meters.

If it's in the air.

The fall time is only four or five seconds.

But in the water, it fell for more than half a minute.

At a distance of two meters from the ground, the container stopped, Tang Qing's mind moved, and the gold bricks on the ground flew towards the container under the action of invisible neural power.

After making sure that there are no gold bricks below.

The container slowly falls.

Sinking into the silt more than thirty centimeters.

The fighters began to put gold bricks into containers, and the submersibles were all recovered.

And Tang Qing.

Started to spin around.

He's going to help.

But not to help collect the gold bricks.

It's packaging and transportation, just one less process, don't forget, he is a person with 'space equipment', a whole thousand cubic meters, really to help pick up gold bricks, where to use containers and soldiers.

He can do it all by himself.

Just a few minutes waiting for the container.

Tang Qing peeled off the thick silt underneath, wanting to see if there were any fish that had slipped through the net, and when the mud more than one meter thick was removed, Tang Qing found a lot of broken gold in addition to the fragmented rubies.

It's not rough.

It's gold ore fragments.

This aroused Tang Qing's curiosity.

That Duke Miyi shouldn't have a brain, there is so much gold, and he throws down this unrefined ore grain, if there is really a large amount of gold ore here, it means that there is a gold mine in the upper reaches of the underground river.

As for here.

Tang Qing was not hopeful.

In the mining conditions at that time.

It is simply impossible to mine gold ore from here, even with the current technology, it is not easy to mine minerals at a depth of 100 meters, unless... Before, the water level here was not so high.

Tang Qing suddenly had such an idea in his mind.

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

"Yes, Commander. ”

Three minutes later.

The roof of the cave flashed again.

A top-like detector falls.

One meter long.

At the moment of falling.

The upper and lower two annular devices begin to rotate, and the left and right sides of each annular device are a laser emitting head, and the principle is also simple, constantly rotating at high speed, and determining the underwater terrain through the reflected information.

Two ring-shaped devices above and below the detector use two lasers with different spectral frequencies.

A probe.

A confirmation.

However, the scattering and refracting ability of water is too strong.

The maximum detection distance is only 400 meters, which is dozens of times shorter than the detection distance on the ground, but in this way, it is already strong against the sky, and it is also against the sky, and the cost of the fucking is also against the sky.

1.6 billion RMB.

This is still the cost price.

It's more expensive than building a satellite, but fortunately, this thing not only detects the underwater terrain, but also has the function of exploring and positioning underwater moving targets for nearly ten kilometers, can find submarines, and can also find schools of fish.

Otherwise.

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

Tang Qing was distressed.

This is also one of the reasons why Tang Qing is crazy about making money, that is, the scientists in the scientific research area have become more and more scientific in contact with each other, and the materials used have become more and more awesome.

The crazy increase in its R&D cost made Tang Qing want to tear it up when he saw the budget table at that time.

It's scary.

Scientific research.

It is still a whole system, and all types of scientific research are carried out at the same time.

It's really burning money with boilers.

Or throw it in one handful after another.

The probe slowly descended at a speed of one meter per second, and on Tang Qing's watch, a projected topographic map starting from the surface of the water was constantly generated, and after more than a minute, the entire topographic map was generated.

When the probe finishes its work, it automatically floats up and is retrieved by the warriors above.

Look at the projection in front of you.

Tang Qing found that his guess was not wrong, this place was really not filled with water before, because during the detection, there was a wooden bridge from top to bottom in the distance, but the wooden bridge had decayed, and only some traces could be seen.

Since the wooden bridge is still more than ten meters below the water surface, it has not been found before.

Tang Qing found that the underground river had two outlets.

One is at the bottom, blocked by stones, obvious artificial traces, because they are all huge gravel, by no means naturally formed, but not tightly blocked, the water is still flowing towards the gaps.

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

Tang Qing immediately understood.

The spout below was previously open.

Come to think of this.

Tang Qing floated underwater.

Come to the water outlet.

Due to the high water pressure, there are constantly undercurrents floating around the gaps, if you get close, you will definitely be sucked over, but the gaps are very small, even if you suck them, it is impossible to suck Tang Qing over.

"What will happen if you get these stones out of the way?" Tang Qing's desire to destroy began to rise.

Do what you think.

Tang Qing touched his hand to a stone.

The neural telekinesis slowly covered and penetrated, and in less than a second, when the neurotelekinesis covered the entire stone, suddenly, the stone disappeared in front of his eyes and was collected into the ring by Tang Qing.

After the disappearance of the stone, the original place was instantly filled with water.

Then thousands of tiny bubbles emerge from the spot, which is a phenomenon caused by the air in the water coming into contact with a vacuum, and the ring collects things, which collects all the particles in the area.

It's kind of interesting to watch.

The stone was not a support point, so it didn't cause anything.

Tang Qing started the next one.

The next minute.

There are constantly dense bubbles floating, Tang Qing also thought about using explosives, but he was afraid that something unpredictable would happen, so it was better to move away the stones that had been moved by others, anyway, he was not in a hurry.

Suddenly.

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

The entire stationary structure was destroyed.

Some of the stones in front of me began to shift and tremble.

At the same time, a huge thrust came from behind him, Tang Qing knew that it was the acceleration of the water flow, he stood at the mouth of the water flow, and the force he felt was not small, but the magnetic field resonance was connected with the earth's magnetic field.

wants to push Tang Qing forward.

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

Pity.

This kind of suction, which ordinary people can't resist at all, can't shake Tang Qing for the time being, watching the tremor of the stone getting bigger and bigger, Tang Qing has no choice but to stand here against the current.

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

"Yes, Commander. ”

After speaking.

Tang Qing walked to the left for about twenty meters, left the range of blocking the rock, and stood on the edge of it, because there were still rocks to hold onto, just in case, if he was unintentionally swept in.

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

When all the fighters have ascended.

Tang Qing began to collect rocks at the edge.

When the third stone weighing several tons is received.

"Boom... ”

The blocking structure in front of me completely collapsed.

Those stones rolled deeper under the tremendous pressure, and the water flow around them suddenly increased, feeling it, but still unable to shake himself, Tang Qing let go of the hand holding the rocks.

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, if it wanted to drain, it was estimated that it would take more than four hours, it was so slow, four hours, Tang Qing should get up.

Suddenly.

Where the stone was washed away.

Tang Qing saw something.

His expression was stunned.

How can there be railroad tracks here?
