Land animals, if they stay in the water for a long time, will have the feeling of being unable to distinguish between up and down, left and right, and they may also have a phobia of the deep sea.

Walking through the sea, they carried a full set of equipment on their backs and only relied on a booster that was held in their hands like a big box.

Under the ocean at night, it looks even more terrifying. Everything is pitch black. Sometimes a fish suddenly appears in front of you, which is like a huge monster that can scare people.

Because they couldn't use lights, otherwise they would be easily exposed, so they moved forward in darkness. Dongfang Leng followed closely behind Yu Fei, like two night elves, their figures flashed past under the sea surface, disturbing many swimming fish.

After advancing like this for two hours, Yu Fei finally stopped, and Dongfang Leng also slowed down slowly and stopped next to Yu Fei.

The two people hid the propeller underwater and held it down with big rocks. They couldn't use it for the rest of the journey, otherwise it would be detected by other people's small sonar radar.

In the darkness, Yu Fei patted Dongfang Leng's head, checked her remaining oxygen level, and made sure she could still hold on, then continued forward.

This time it felt like 20,000 miles under the sea. Yu Fei and Dongfang Leng were moving forward close to the bottom of the water. Because of the water pressure, Yu Fei always tried to stay about ten meters away from the water surface. This distance was the least likely to be discovered.

It is easy for people to accept the water pressure, and it will float quickly if there is an accident.

After advancing like this for half an hour, Dongfang Leng's oxygen was almost exhausted. Yu Fei stood behind her, took out a new oxygen bottle from the Dragon Ball space and replaced it with her.

Dongfang Leng didn't ask anything. She was originally going to use her ability to control water, but she wouldn't be able to last long. With a new oxygen bottle, she could move on.

The two of them kept moving close to the bottom of the water, so that it would be difficult for the islanders' detection equipment to detect them.

Moreover, Yu Fei knew that there must be frogmen from the other side patrolling near the port, and it was even said that there might be trained dolphins and other creatures to patrol on their behalf.

After Yu Fei changed oxygen bottles for Dongfang Leng three times, Yu Fei suddenly pulled Dongfang Leng and dived a certain distance, hiding in a gap between rocks.

After more than ten seconds, a small submarine slowly passed by above their heads. This thing was obviously not used for combat, but for patrolling. There were lights on it that illuminated the surrounding area, and it slowly passed over Yu Fei and the others.

Seeing that the other party had gone far, Yu Fei pulled Dongfang Leng and continued to move forward. Soon it was dawn. If he continued to move along the beach, for example, just ten meters above the water, he would be very likely to be discovered, because when the light becomes stronger, it is almost impossible to pass through the water.

Everybody can see them.

Yu Fei took Dongfang Leng and dived deeper into the water. He stayed at about twenty-five meters and continued moving forward close to the bottom of the sea.

Along the way they encountered two patrolling small submarines and a wave of frogmen, all of which they avoided.

The main reason is that Yu Fei moves close to the bottom of the sea and can make good use of obstacles to avoid the search of the opponent's sonar and other high-tech items. Once encountered at close range, he can quickly find a hiding place.

And it was definitely a wise choice to abandon the thruster early, as the opponent even installed detectors underwater.

Because ordinary people have to rely on oxygen supply equipment to swim in by themselves, which is almost impossible, because the oxygen supply of oxygen bottles is limited, and people’s physical strength is also limited.

So if you want to approach from a safe place, you can only use thrusters.

But they never imagined that Yu Fei and Dongfang Leng could stick to the bottom of the sea, and it was impossible for the frogmen to swim past the distance, and they were constantly approaching.

Even Yu Fei walked through the whole process without changing the oxygen bottle even once. Dongfang Leng didn't ask anything and pretended not to see it. This was a tacit understanding.

The two of them didn't even use communication equipment, because they only

If you want to use it, you will leave signals that can be detected such as electromagnetic waves and expose yourself.

If they encounter the opponent's large army of frogmen in this deep sea, Yu Fei and Dongfang Leng will have nowhere to show their strength.

After swimming forward for a while, Yu Fei saw a fast black figure in the distance. He hurriedly pulled Dongfang Leng down and dived two meters. He lay down directly on the seabed. Yu Fei used his hands to stir the water.

The dust was stirred and floated up, covering their individual figures.

A dolphin with a camera and detector attached to its fin swam past their heads, unaware of the turbid water.

The current slowly opened up the turbid water, and Yu Fei and Dongfang Leng continued to move forward.

Due to swimming in the water for a long time, Dongfang Leng's physical strength was severely exhausted, so Yu Fei quietly transferred a large amount of spiritual energy to her so that she could keep up with Yu Fei's pace.

After advancing for a while, suddenly in the sea water in front, a huge net with no end appeared. This is another artifact to prevent frogmen from sneaking in. There are sensors inside. If you destroy this net, you will also

be found.

It cannot be destroyed violently, and it is impossible to dig underneath it, because this is the bottom of the sea, and digging casually is digging your own grave.

So they swam forward carefully along the net. Once they found something abnormal, they would fall to the bottom of the sea and hide. If they couldn't find a hiding place, they would muddy the water.

After advancing a long way in this way, they finally discovered the entrance and exit passage left by the other party for their own submarine.

It is near this passage that there are surveillance cameras and frogmen.

Breaking in by force or sneaking in is not possible, he is neither blind nor stupid.

Yu Fei looked at the time. He had actually calculated this. There was still an hour before the time suitable for sneaking in. Yu Fei took Dongfang Leng away a little further, and the two of them hid in the cracks of the rocks.

Fortunately, Chen Dong prepared enough oxygen tanks. Yu Fei waited for a while and replaced Dongfang Leng with new ones.

The light on the water above our heads became fainter after passing through the water for a short time. When we looked up, we saw that it was not the entire blue sky, but just a small, slightly brighter halo.

Fortunately, Dongfang Leng was born as a killer and has good resistance to loneliness and this kind of environment. If an ordinary person were to be in this kind of environment for a few hours, they would not be able to bear it psychologically and mentally.

The time was almost up, Yu Fei was holding on to the time and kept stretching out his hand to feel the changes in the ocean current.

Dongfang Leng knew what Yu Fei's plan was, so he was conserving his energy to prepare without moving.

Yu Fei finally felt the ocean current rushing towards the port. The tide was about to rise!

Yu Fei and Dongfang Leng quickly swam out of the gap between the rocks. After making sure that the surroundings were safe, they frantically clung to the bottom of the sea and began to stir up the mud on the bottom of the sea.

A large amount of water began to be stirred and became turbid, and followed the ocean currents and continued to move towards the gap left for the submarine.

Yu Fei's efficiency was the highest, as if a fish was churning on the bottom of the sea and moving laterally, because he wanted to create the feeling that this was a natural phenomenon. If there was only a cloud of turbid water passing by, it would be too obvious on purpose.

A large amount of water was stirred up. In order to move quickly and effectively, Yu Fei and Dongfang Leng spent a lot of internal energy, and then quickly swam over and hid themselves in the turbid water.

In this way, the frogmen guarding the gap also felt the changes in the ocean currents, and then discovered that the water became turbid. This situation occasionally occurs during high tide, but they are used to it, so they did not pay attention.

However, the water became more and more turbid and the area became larger and larger, enveloping them all. They were helpless because they could not see anything.

Just when they were about to turn on the detection equipment to prevent anyone from swimming in through the turbid water, Yu Fei and Dongfang Lengzheng

I finally passed by five or six frogmen. The turbid water blocked my view, and the changes in the ocean currents hid the movement caused by the stirring of the water when Yu Fei and the others swam.

They had just opened it through the detection equipment. The frogmen of the island country stared at the detection screen and continued to guard with peace of mind, waiting for the replacement person to come over. Unexpectedly, they had just reacted a little slower, and Yu Fei and Dongfang Leng had already entered.

After passing through the blockade, Yu Fei and Dongfang Leng continued to move forward close to the sea. Ports are usually built close to the coast but deep enough so that large ships can dock. The advantage is that the water is deep enough for Yu Fei and the others to hide.

Even though they did everything in silence, in fact they passed through five blockades. It was just an offensive and defensive battle on the seabed. That was it. Either they were not discovered or they were besieged, and the bodies did not even appear.

On the sea.

This is one of the most important ports in the island country, so it is very tightly defended. It is impossible for ordinary frogmen to enter here. Only a pervert like Yu Fei can carry a large number of oxygen bottles, carry Dongfang Leng with him, and persist in the sea.

It takes more than ten hours to get here.

But I originally thought that after passing through the blockade that was almost impossible to break through, the defense inside would be lax. Unexpectedly, the islanders were very cautious, and there were actually more frogmen inside holding underwater firearms.

patrol.

Yu Fei and Dongfang Leng were having a hard time moving forward. After advancing for a certain distance, they had to hide and watch the frogmen above their heads swim slowly past.

At this speed, Yu Fei and the others still need at least ten hours for the last distance. That's nonsense. Even if Yu Fei's Dragon Ball space can hold it, Chen Dong has not prepared so many oxygen bottles. Dongfang Leng

I simply can't hold on.

So we have to think of a way to hunt down other people's frogmen. This is a way, but Yu Fei doesn't want to do it. In his plan, he needs to stay here for many days. If he does this, he won't be able to persist.

Finally succeeded.

So Yu Fei needed to find something suitable enough to cover their bodies, and then speed up their progress.

So while moving forward, I was searching. This is a port after all, so a lot of things have accumulated under the water over the years.

But some boats or big rocks cannot be moved at all.

After spending several hours, Yu Fei finally found a good thing, a broken wooden table. It had probably been thrown into the water for a long time. The legs of the table were rotten and broken, and the remaining tabletop was dark and ugly.

This tabletop is big enough to hide Yu Fei and Dongfang Leng. Because one side is covered with metal, it will not float up.

Yu Fei carried the tabletop on his back and dragged it forward with his back together with Dongfang Leng. Yu Fei's super eyesight could usually spot the opponent's frogmen first, so he and Dongfang Leng would stay down and let the tabletop naturally press on them.

In this way, they didn't need to waste a lot of time looking for a hiding place, so they speeded up a lot and moved forward thousands of meters again.

Yu Fei finally saw a huge warship sailing slowly above his head, making the bottom of the sea even darker.

Yu Fei hurriedly took advantage of the darkness and quickly advanced a certain distance with Dongfang Leng.

The warship was much faster than them, and when the light slowly recovered and they could see for a certain distance, Yu Fei first spotted a lazy frogman on the other side, very close to them.

Yu Fei quickly pulled Dongfang Leng and landed slowly. When they landed on the sea, the frogman could finally see them. When the frogman saw the rotten tabletop, he frowned in confusion.
