This planet has been abandoned for more than a decade, and everything is a thing from more than a decade ago.Because of the war, this rusty submarine has become the best submarine, and engineers can only modify it with a hard scalp.

This renovation project lasted for three hours, and Yu Yifeng could not wait and directly dialed the phone of the engineering department.

“Is it performance or not?”

He saw various data forms sent by engineers on the screen and frowned.

"Yes, this submarine is in disrepair and many functions are lost!"If you dive 500 meters, it is estimated that you will not be able to withstand the pressure!We don't have enough industrial systems on this planet, and the current pace of adaptation is too slow."

“And the planet doesn’t have enough supporting parts, and there’s no superalloy or anything like that...” The engineer across the screen said in embarrassment... With his hands on his hands, the smart woman was struggling to make it to the rice-free.

"Then the submarine can dive for a few hundred meters!"Not necessarily used...”

Yu Yifeng waved, he understood the engineer's dilemma, but there was not enough patience to wait any longer.

No one knows when the crisis will occur, all you have to do now is race against time!

A quarter of an hour later, more than thirty elite soldiers and more than two dozen scientists were urgently conscripted and stepped onto a transport ship, which was carried even with the old submarine.

No way, from the northern hemisphere to the southern hemisphere, you must use the spacecraft, otherwise the submarine slow swimming past do not know how long, ten days and a half months are possible!And this raging submarine is not expected to swim so far...

This is a little risky, but the risks are manageable.After all, the flight in the atmosphere is still not very conspicuous, like a normal aircraft, it is no big deal.

The soldiers were almost fully armed, and they did not even eat lunch, and they could only cope with the matter in the ship.

And many scientists are excitedly pointing at the ocean, and they have never seen such a magical phenomenon:

The ship was flying almost 10,000 meters high on the sea level.Through the glass window, a green band appeared throughout the ocean to guide them.

It must be said that the whole ocean is the essence of Ling, like her limbs... It is still difficult to let her abandon here and follow people on the ship.

But . . . again, it is also this first birth that there is a possibility of “abduction”.When you are older, it is not easy...

Seeing the ship in the sky following her movement, Ling seemed to have fun, but she remembered her promise not to take people around.

After about three hours, the speed of the ship slowed down and fell from the sky.

After gliding over the water for a distance, this base floated like a ship on the water.

“Is that it here?”Yu Yifeng asked the ocean.

A small ball suddenly appeared on the sea surface and jumped up and down, indicating a nod.

“Unmanned Submarines!”

With a single order, thirty small unmanned submarines were released from the spacecraft to explore the ocean.

This is the shallow sea area, not very deep, the maximum depth is 200 meters, the shallowest depth is less than ten meters, which also makes everyone a little relieved ...

Inside the ship, everyone is staring at the advance of the unmanned submarine, and through the camera installed in the front, each screen represents a submarine.

These unmanned submarines are also one meter long, can not be manned, the power device is small, the forward speed is not fast, about 30 kilometers per hour.

When it was originally designed, these were mass-produced consumables, and it could not be too high-end.People reach the current level of interstellar civilization, still have to follow industrial economics, conventional aluminum alloys, titanium alloys are still used, it is impossible to use any new superalloy material for any one thing.

All along the way, there were all kinds of strange sea creatures everywhere.Biologists are not idle these days, they have captured a large number of specimens, and it is not surprising that these things are also strange.

Everyone was staring at the screen, staring at the screen, trying to spot the traces of alien bases.

The atmosphere slowly became tense...

“Look, look there!”

One of the soldiers shouted in surprise.

Dozens of eyes Zisensen looked at the past, and gradually, people saw some end.The sea here is 160 meters deep, and the bottom is something similar to a coral reef.But it is clear that this coral reef has been dumped by heavy objects, and has not yet been restored to its original state.

According to the detailed calculations of the scientists, the area that was dumped was almost as large as a flying saucer!

That’s it... that flying saucer, which was once stopped here!

“Let’s see if there are any buildings!”Take the command immediately.

But after the surprise, people were quickly disappointed, because there were no other man-made buildings except corals.

"Wait a minute, these corals are not growing at a slow rate, is it possible to bury alien structures?"After all, alien flying saucers have been here for 30,000 years.

A scientist exclaimed urgently: "30,000 years of kung fu, the terrain has long changed, and everything may be hidden!"

This is very possible, but something that has been too long, "ling" has not been self-conscious, has no memory, asked her for half a day did not know.

People can only reluctantly search back and forth through unmanned submarines.

Yu Yifeng frowned and thought, such a large ocean, even if there is something hidden under the sea, people are difficult to find out in the short term, is it necessary to dig a hole in a large area with a machine?

He looked at the little green ball that was beating in the ocean, and suddenly he had an idea in his heart.

Despite the dissuasion of the people, he put down a kayak and jumped in, close contact with the sea.

He played with the ball for a while and then said, “Can you help us?”Hit a few holes in the bottom of the ocean and see if there’s anything very hard down... for example, metal or whatever...”

People's large machines can do this, but large-scale hole-in-take is quite time-consuming, rather than using this ready-made helper.

Hardly communicating for half a day... The temperature inside the power armor is quite appropriate, but Yi Feng is tired and sweating... This feeling is like directing the baby to help you, when the spirit is not working, everything depends on the other person's mood.

The ball beat a few times, and at first I did not understand it, until Yi Feng persuaded him for half a day, and he reluctantly agreed.

The sea was calm for a while, and for a few minutes, it began to beat cheerfully again, and at the same time tugged the kayak in one direction.

There was a surprise in everyone’s heart, did they really find something?

It is a shallow water area six kilometers away from the flying saucer, and less than ten meters from the sea.After a while, people finally found out...

One of them...square!

Although buried by thick coral reefs, a square iron is exposed inside!There may be artificial buildings below!

“Let’s clean it up, okay?”

Yifeng is both surprising and somewhat embarrassed, and now everything seems to ask her... After all, let Ling help, in order to solve it quickly and well, he can only be thick-skinned and scraped together.

Communication between the two sides was not an easy task, and the pen was strung for half a day, and Ling was not very happy to agree to Yi Feng's request...

What’s wrong with this guy, always letting himself dig?This phantom green ball is not happy to beat.

Through the submarine's camera, people only saw that there seemed to be an invisible hand in the ocean, and the hard coral-like creatures above began to disintegrate rapidly.This surprised the scientists.
