It's an underwater world shrouded in darkness, and there is no light at all, except for the occasional glowing sea creatures that swim by, and naturally nothing can be seen.

Suddenly, a powerful beam of light was projected from the sea water above, like a bolt of lightning, directly cutting through the darkness and bringing light to this dark underwater world.

Immediately afterward, a glowing droplet-shaped object slowly fell, breaking into this dark underwater world.

Stimulated by the bright light, many of the sea creatures that had been living at this depth and swimming freely immediately dispersed and fled in all directions, fleeing to the sea water that was still shrouded in darkness in the distance.

Among them, there were also some brave guys, and after swimming a certain distance, they found that the droplet-shaped object that was emitting a bright light did not attack or threaten, and immediately stopped.

They all turned around, curiously gazing at the strange glowing object, and some of the sea creatures even swam in this direction, ready to get closer.

At this moment, there was suddenly another powerful beam of light not far away, still coming from the sea water above.

The next moment, a larger droplet-shaped luminous object fell from the sky and came to this dark underwater world.

Not surprisingly, this underwater world once again set off a whole commotion, and the movement was even bigger.

These two sudden droplet-shaped luminous objects were the two Aurora small submarines that were dropped from the Brave Intrepid, the smaller one was led by Mattis, and the larger one was led by Ye Tian himself.

After about 10 minutes of diving, two small Aurora submarines, one large and one small, have successively dived to a depth of about 160 meters below the surface of the sea.

The arrival of the two Aurora mini-submarines is like two small suns falling from the sky, suspended in the dark water, echoing each other from afar, which is extremely eye-catching.

In particular, the arrival of the second mini-submarine not only brought light to this dark underwater world, but also brought a lot of marine life, among which there were dolphins, red sea turtles and so on.

The Mediterranean dolphins, in particular, rushed out as soon as they reached this depth, and began to chase the other frightened sea creatures, causing chaos here.

It looks like they're hunting, but it's more like they're playing and frolicking!

However, the two huge red sea turtles still stayed honestly next to the small submarine that Ye Tian and they were riding, and they were reluctant to leave for a moment, just like two door gods!

After diving to a depth of one hundred and sixty meters, both mini-submarines suspended their descent and suspended at this depth.

This is a strategy that everyone has agreed on in advance, and it is also for the sake of safety.

Compared with the previously explored English Channel, there is relatively little hydrogeological data in this area, and whether those hydrological data are reliable is still a matter of two opinions.

In addition, the Ionian basin has frequent seismic activity, and the topography of the seabed has changed, so caution must be taken.

Because of this, Ye Tian and the others chose to pause at this relatively safe depth, adjust it here a little, and then reduce their speed and gradually explore the dive.

As soon as the submarine stopped, Ye Tian said through the walkie-talkie:

"Mattis, prepare to activate the submarine's own wireless underwater communication equipment, top-level tracking system, and GPS tracking device, and then disconnect the cables and oxygen pipes on the top for the Intrepid to retract.

When I dived to about 95 meters, I found an undercurrent, which was probably caused by the huge difference in the topography of the seabed and the different salinity of the upper and lower layers of the sea, so I had to be more careful.

When we reach Hailing, the Brave Intrepid will put down the decompression stop, if we accidentally touch the undercurrent, driven by the undercurrent, it may be twisted with the cable and oxygen pipe on the top of the submarine.

In this case, it is better to disconnect the cables and oxygen pipes on the top of the submarine and use the submarine's own electricity and oxygen production equipment, in fact, it is more free and easier to move."

"Understood, Steven, let's contact the Dreadnought on the surface and disconnect the cables and oxygen pipes on the top of the submarine."

Mattis replied in a deep voice, and then went into action.

At this moment, the voice of the host of the live broadcast group of NBC TV suddenly came from the walkie-talkie.

"Steven, if you disconnect the submarine from the cable connecting the Intrepid to the sea, will it affect the live broadcast?"

Hearing this, Ye Tian immediately smiled and said:

"Don't worry, Peterson, the two deep-diving decompression stops that will be put down immediately are also two communication relay stations, and they carry high-tech underwater communication equipment that connects the seabed to the surface.

In other words, no matter what we see on the bottom of the sea and what wonderful pictures you shoot, they can be transmitted to the sea surface and countless live broadcasts as soon as possible, without the slightest delay."

"Wow! That couldn't be better."

Peterson exclaimed and said nothing more.

Next, the two small submarines disconnected the cables and oxygen pipes at the top one after another, allowing the Intrepid to be moored on the surface of the sea to take it back.

Immediately afterward, the Intrepid lowered the two deep dive decompression stops to an intermediate depth of about 90 meters, and then suspended there.

At a depth of one hundred and sixty meters below the surface of the sea, the two small submarines that had been untied had already converged in one place, and they were only a dozen or twenty meters apart from each other.

People in the cockpits of two small submarines can see each other clearly as soon as they turn their heads, not much different from on the surface of the sea.

"Matisse, dive a few meters further, you should be able to see the peak of the ridge below, during the dive, the speed must be slow, safety first, try to avoid the edge of the cliff, and be careful of cracks and sea holes.

If those ancient Roman shipwrecks landed on the ridge, they must be in a relatively wide and flat place, so there is no need to explore the towering peaks, and after reaching the peak, we will search side by side, left and right.

Turn on all the lights at the bottom of the submarine, dispel the darkness below, and see what's down there, and if you find something and can't confirm what you've found, you'd better let me know in time."

Ye Tian said through the walkie-talkie, and stretched out his finger to the sea water shrouded in darkness below.

In the five Aurora mini-submarines not far away, Mattis immediately nodded in response.

"Understood, Steven, we'll be careful"

"Okay, let's get started, I don't know what awaits us in that dark world below, I hope it's a huge surprise"

Ye Tian nodded with a chuckle and said, giving the order to act.

Before the words fell, the lights on the bottom of the two mini-submarines were all turned on, and the light emitted suddenly became more intense.

As several powerful beams of light shot to the bottom of the sea, a ridge towering above the bottom of the sea has loomed into everyone's field of vision.

The picture presented on the monitoring screen and the countless live broadcasts is a heavy shadow.

Even if it's just a shadow, it's still a chorus of exclamation.

"Wow! Steven's gang were lucky enough to find the first ridge so quickly, I wonder if they could find something?"

"I have to say, this kind of undersea exploration is really exciting, I wish I was in those two small submarines!"

Just when people were amazed, Ye Tian glanced at the shadow below, and then said with a smile:

"Let's go, guys, let's go down there and have a look."

As the order came out, the two Aurora mini-submarines began to dive again, continuing to dive deeper into the ocean.

After only five or six meters of diving, the top of a towering mountain appeared diagonally below the two small submarines.

This submarine mountain is very steep and covered with a variety of corals and seaweed, and it is very colorful and beautiful when illuminated.

Among these corals and seaweeds, there are many beautiful marine creatures that live here.

It's just that because of the arrival of two small submarines and the group of Mediterranean dolphins, these frightened sea creatures immediately dispersed in a hurry, quickly fled to a distance, or found a place to hide.

On the east and west sides of this towering peak, there are thousands of cliffs, and down the cliffs, there is an endless abyss, and the darkness that you can't see your fingers, which makes people dizzy to look at!

The terrain on the north and south sides of the peak is relatively gentle, but due to the limited range of the searchlights, there is no more to be seen for the time being.

Ye Tian quickly glanced at the undersea terrain, and then said loudly:

"As far as the current situation is concerned, this ridge is a north-south trending ridge as described in the relevant hydrogeological data, with a huge drop and cliffs everywhere.

The ancient Roman shipwreck treasure we are looking for is obviously not on this peak, Matisse, let's explore the south along the mountain, and then turn back to explore the north."

"Okay, Steven, let's get started"

Mattis responded, a little impatient to hear the tone.

Next, the two small submarines continued to dive, slowly reaching a place five or six meters above the peak of the submarine mountain, and maintained it at this depth.

Immediately afterwards, the two small submarines adjusted their direction and slowly explored and advanced to the south along the mountain terrain of this ridge.

With their movements, a more beautiful Mediterranean underwater world suddenly appeared in front of Ye Tian and them, as well as in front of countless viewers on the live broadcast end.

Not surprisingly, this drew another wave of amazement.

But people are more concerned about the ancient Roman shipwreck, the sculptures of the Roman or Hellenistic periods, and the antique works of art!
