After driving away the giant squid, the submarine slowed down and began to search carefully in the nearby waters according to Ye Hao's instructions.

In the process of searching the bottom of the sea, Ye Hao saw many wonderful scenes that he had never seen before.

There are red transparent jellyfish with a diameter of more than 10 meters, giant spider crabs with limbs more than 4 meters long, swarms of weird tube worms with a length of more than 1 meter, and a king herring that looks like a king-sized ribbon fish with a length of more than 12 meters.

These rare deep-sea creatures made Ye Hao and them all fascinated and amazed.

Before you know it, the submarine has been on the bottom of the sea for three or four hours.

Ye Hao and the others saw many rare deep-sea creatures, but they did not find any traces of black fragments.

"Ye Dong, we have been around the bottom of the sea for a long time. The space of the submarine is claustrophobic and isolated, and I am afraid that you will have psychological discomfort if you stay in it for a long time. Why don't we float above the surface and get some fresh air?"

Peng Wanli said.

"Don't worry, I've only been looking for three or four hours. I have time, and I don't feel any discomfort, so let's search a little longer!"

Ye Hao said.

"Uh...... , well!"

Peng Wanli saw that Ye Hao's addiction was so big, so he had to stop saying anything.

Not long after the exchange between the two ended, Ye Hao made a major discovery.

"Stop the submarine! Turn your searchlight to the bottom of the sea, fifteen meters in front of you!"

Ye Hao suddenly pointed out the porthole and shouted.

Peng Wanli was stunned for a moment, and turned his head to look out of the porthole.

However, when he looked in the direction of Ye Hao's finger, he didn't see anything noteworthy, only saw two fish swimming around on the bottom of the sea.

However, he still followed Ye Hao's instructions and asked the crew to stop the submarine and shine multiple searchlights together.

That location suddenly became brightly lit.

Peng Wanli's eyes widened, and after a closer look, he still didn't see anything noteworthy.

"Ye Dong, are you dazzled? there's nothing there!"

Peng Wanli muttered.

"No, it's there!"

Ye Hao waved his arms excitedly.

"Wow, really! Ye Dong's luck is so good, he only searched for a few hours at the bottom of the sea before he made a major discovery!"

Popeye also saw it and let out a cry of surprise.

"Haha, Ye Dong's eyes are still pointed, if it were me, I would probably miss this thing!"

Zhou Haitao also said excitedly on the side.

Peng Wanli was so excited when he saw Ye Hao, and thought that there was something wrong with his eyes.

He ran to the monitor's screen again to take a closer look.

Many high-definition cameras are installed on the exterior of the submarine, which can be used to observe the external environment more clearly through the screen of the monitor.

He asked the crew in charge of the monitor to adjust the angle of the camera, aimed it in the direction that Ye Hao was pointing at just now, and enlarged the picture. At this time, he realized that there was indeed a black bulge on the mud on the bottom of the sea.

It looked like a black piece of metal, and because the surface was covered with a lot of silt, it was easy to mistake it for a rock raised from the bottom of the sea, or the remains of some hard-shelled creature.

"Ye Dong, this is the treasure you are looking for?!"

Peng Wanli was speechless for a while.

In his opinion, this kind of thing is nothing unusual.

"Quick, do you guys have any way to get that thing back on the submarine?"

Ye Hao asked.

"Yes, yes, you can send out an underwater robot. But is it really necessary?"

Peng Wanli was still quite confused.

"Of course it is necessary! I am looking for this submarine that the military wants just to find it!"

Ye Hao shouted.

"Uh...... , okay then, I'll arrange it!"

Only then did Peng Wanli begin to pay attention to it.

Soon, from the torpedo embrasion of the submarine, an underwater probe with a very special shape was launched.

The detector was oval-shaped, only one meter long, with a circular searchlight mounted on top, as well as separate drive and detection systems. Because this probe has a movable metal arm that can be controlled remotely, it is also called an underwater robot.

A minute or two later, the underwater robot arrived at the location of the black fragment.

Ye Hao and the others all gathered in front of the monitoring screen, watching intently the process of the underwater robot digging up the black fragments.

When the robot dug the entire black fragment out of the mud, Ye Hao and the others let out a burst of excited cheers.

It is a black fragment more than half a meter long, in the shape of a long strip, about five centimeters thick, with incomplete edges and some strange bumps and textures on the surface.

"Hahaha, that's it!"

Ye Hao waved his arm excitedly.

After a few more moments, the underwater robot returned to the submarine with the sludge-stained debris.

Ye Hao's mood couldn't wait, and he directly asked Peng Wanli to take him to the torpedo launch compartment, to get this piece of fragment as soon as possible.

When Ye Hao saw this fragment in the recovery bin of the torpedo launch compartment, he cheered excitedly again.

He quickly cleaned the surface of the debris from the silt with water, which was then directly stored in the system's storage space.

Peng Wanli and the two crew members who accompanied him didn't see what this fragment looked like, and they saw that the fragment suddenly disappeared inexplicably.

"Wo Cao, where did that piece of debris go, has it evaporated?"

Peng Wanli exclaimed in shock.

"Don't panic, I just put this thing away!"

Ye Hao said with a smile.

"Got it, where did you get it?"

Peng Wanli was even more shocked.

Ye Hao didn't explain more, but urged Peng Wanli to let the submarine continue to sail forward and continue to search for this black debris.

Two hours later, Ye Hao was lucky to find a fragment again.

This newly found fragment was only slightly larger than the palm of his hand, and if it weren't for Ye Hao's strong eyesight, it would have been easily missed.

Finding two fragments one after another made Ye Hao's mood very excited.

"There must be other fragments in this sea! Keep looking, you must find them all!"

Ye Hao said excitedly.

"Ah, Ye Dong, you've been underwater for six or seven hours, and you still want to stay at the bottom of the sea?"

Peng Wanli began to worry about Ye Hao's health.

Generally speaking, people who go on a submarine for the first time will have a strong psychological discomfort if they stay in this claustrophobic and oppressive environment for too long. Severe mental illness that may even produce hallucinations and auditory hallucinations.

Even they, well-trained professional soldiers, had to go to the surface to breathe after several days of continuous diving on the bottom of the sea. Otherwise, even they would go crazy.

"I'm fine! I'm feeling so good now!"

Ye Hao said with a smile.

This surprised Peng Wanli even more.

Judging from Ye Hao's expression, he was indeed very relaxed and happy, and there was really no uncomfortable reaction.

However, Popeye and Zhou Haitao are already obviously a little anxious.

"You two, are you feeling a little uncomfortable?"

Peng Wanli asked.

"Ahem, it's okay, I'll hold on!"

Popeye said stiffly.

Zhou Haitao didn't speak, but his face was obviously ugly.

Ye Hao noticed that there was something wrong with Popeye's expression, so he quickly took out two milky white pills and handed them to Popeye.

"Take the pill, and you'll be fine!"

Ye Hao said.

Popeye and Zhou Haitao both trusted Ye Hao very much, and without saying a word, they took the pill and swallowed it in one gulp.

Sure enough, after a few seconds, the faces of the two of them became obviously ruddy, and their mental state appeared to be very good.

Peng Wanli watched from the side and couldn't help but be amazed.

"Ye Dong, what kind of elixir did you give the two of them? I see that not only has their complexion improved significantly, but even their spirits have become much more vigorous!"

Peng Wanli asked curiously.

"Hehe, this is called a little elixir, it's not a too expensive elixir, but for ordinary people, it's still a rare treasure!"

Ye Hao said with a smile.

"Wow, it turned out to be a little elixir!

Peng Wanli had a very envious expression on his face.

He and the other submarine crews, because they had been working in submarines for a long time, were very eager to get this panacea that would eliminate claustrophobia. If they could get this miracle medicine, they wouldn't suffer from the pain of claustrophobia.

Ye Hao saw the longing in Peng Wanli's eyes, and said with a smile,

"I have a lot of small elixirs of this level, how many I want, how many I want! If you want it, I'll give you a few each!"

Ye Hao said, took out a delicate pill bottle, and threw it to Peng Wanli.

"Hey, Ye Dong, this can't be helped! We are embarrassed to ask for such a valuable pill!"

Peng Wanli was a little flattered.

"You're welcome, I told you, I have a lot of this elixir here!"

Ye Hao said with a smile.

"Thank you so much Ye Dong! Thank you so much!"

Peng Wanli said excitedly.

Cautiously, he opened the lid of the pill bottle and glanced inside.

A refreshing fragrance suddenly wafted out.

Peng Wanli and the two crew members next to him felt refreshed just by smelling this scent.

"Wow, this is really a treasure! Tsk, there are at least two hundred pills in the bottle, right? Ye Dong is so bold! We don't know how to thank you!"

Peng Wanli was a little incoherent with excitement.

"Hehe, don't be so polite! I have to work hard for you this time, stay with me at the bottom of the sea for a few more days!"

Ye Hao said.

"Ye Dong, don't worry, we promise to complete the task!"

Peng Wanli excitedly immediately gave Ye Hao a military salute.
