The short-term disappointment did not last long, and soon, Song Wenbin and Huo Yu had to take out the water again to refill the oxygen cylinder. Coming out from a depth of thirty meters underwater, the huge pressure difference made Huo Yu couldn't help but feel a burst of severe discomfort, let alone Song Wenbin.

As soon as he came out of the water, he felt joint pain, muscle soreness, and even difficulty breathing, which was a sign of the sudden drop in pressure and the bubbles clogging the blood vessels.

Fortunately, the photographers on standby on the boat were professionally trained, and they dragged Song Wenbin to the kayak, constantly massaging his body, and pressing a pure oxygen mask on his mouth to let him breathe intermittently.

】

After inhaling pure oxygen and air alternately for more than ten minutes, Song Wenbin felt that the pressure on his body and the pressure from the outside had reached a balance, and he slowly recovered.

However, it is not the end, on the contrary, it is only the beginning.

The atoll is no better than the reef, the area is small and easy to explore, an atoll is more than ten kilometers wide, after a short rest and supply, Song Wenbin and Huo Yu had to go into the water again.

This time, they searched underwater for another hour, but found only a few glass bottles, discarded fish hooks, and rusted tin buckets.

Undeterred, the two men went from noon to dusk until the sun went down before they returned to the yacht's water platform.

Su tina squatted on the edge of the hydrophilic platform, holding the camera and flipping through the objects salvaged by Song Wenbin and Huo Yu, her face could be said to be ugly and ugly.

There is no doubt that this day's search once again pressed her prediction to the ground, and apart from the garbage, there was no trace of the so-called historical artifacts under the water.

Song Wenbin and Huo Yu rested on the bulkhead with their bodies wet, and the photographer and director on the side held the camera, and the atmosphere in the cabin was heavier than at any other moment.

"How so..."

Sutina rummaged through the garbage and muttered, "Could it be that there is a mistake in the record, or that we are late..."

Looking at Su Tina's dejected appearance, Huo Yu straightened up with difficulty, comforted her and said: "It's okay, we just explored a few shallow water areas, and there are still many deep water areas on this coral reef that we haven't explored. ”

Now, there is no other way.

Song Wenbin looked at the depressed Su Tina and Huo Yu, who pretended to be calm, he leaned against the bulkhead and let out a long sigh.

If he could, he really didn't want to experience helium-oxygen diving, or even crazier saturation diving, and he swore it was one of the last things he wanted on this planet.

......

Late at night.

Song Wenbin stood alone on the flybridge of the yacht, holding a bottle of beer, silently watching the dark sea and smoking. The magnificent waters of the sea during the day seem so calm at night, it remains eternally silent, indifferently withholding from the sea all eyes that dare to peep into its mysteries.

After drinking beer for a while, there was the sound of soft footsteps behind him.

Even if Song Wenbin didn't look back, he knew who was coming, and after being together for such a long time, he already knew very well the footsteps of his colleagues.

"The Shenxing Taibao has already set off, and we will be able to reach this sea area at eight o'clock tomorrow morning." Huo Yu stood beside him and said.

"I see." Song Wenbin said softly.

Huo Yu looked at Song Wenbin's side face and the cigarette butt between his lips, and couldn't help but say: "Don't smoke, it's not good for your lungs, you have to go into the water tomorrow." ”

Song Wenbin felt that he was already going to dive into helium and oxygen, and he still cared about this cigarette, he shook his head, took a deep puff of the cigarette, and asked, "If I can find it, I don't mind if my body is damaged a little." But what should we do if helium and oxygen are used and still can't be found? ”

For Song Wenbin's question, Huo Yu couldn't answer.

It has been 10 days since they arrived in Indonesia, and yet 10 days have passed, and they have not made any progress at all, which was almost unimaginable in the past mission. There is no doubt that any previous task seems so easy compared to this one.

"If we really can't find it, we'll have to go back."

Huo Yu said calmly: "This is reality, we must accept it. There are only so many clues that the country can give us, and we will do our best. ”

"Yes."

Song Wenbin spit out a puff of cigarette and sighed: "After investing so much, in the end, the bamboo basket was empty, it's difficult." ”

"It's normal to fail." Huo Yu said: "Actually, what I care more about is that if I fail this time, can the show continue to be filmed in the future." ”

"It doesn't matter to you."

Song Wenbin said: "Isn't it good that the show is no longer filming, and you continue to be your safety director, run the dragon farm, and be a little rich woman?" ”

"Is life just life for you?" Huo Yu asked rhetorically: "Is this show just a job for you?" ”

Song Wenbin was stunned for a moment, he couldn't help but look at Huo Yu beside him, under the wrapping of the night, the lines on her face were softer than any moment in the past, the faint sea breeze lifted her short hair and outlined it under her neck, he seemed to be able to read some unusual history from the other party's face.

"You... Mother... He must be a very gentle person. ”

Song Wenbin couldn't help but ask.

Huo Yu took a step back in astonishment and looked at Song Wenbin incredulously.

"Ah, don't mind, I'm just talking about it casually."

Song Wenbin realized his short-term gaffe, he suppressed the strangeness in his heart, and said: "I'm sorry, I never think about these things that I have, but maybe you're right, life is just life for me." ”

After speaking, he extinguished his cigarette, passed by Huo Yu, and returned to his cabin.

......

The next morning, Song Wenbin woke up from his sleep, only to feel that every bone in his body was in slight pain, and his eardrum was also swollen and painful. This is the sequelae of yesterday's diving, and this is the result of his physical fitness has been greatly improved, he can't even think that if this is the body of a year ago, I am afraid that he is now in the ICU of the hospital.

However, he couldn't complain a few more words, there was already a sound of hurried movement outside the cabin, Song Wenbin got up and opened the door and came to the deck to take a look, it turned out that the Shenxing Taibao had arrived, even an hour faster than the scheduled time.

At this moment, the Shenxing Taibao is lying quietly on the sea surface not far from the Three Treasures, like his ancestors, with a majestic hull of more than 70 meters, and ten huge sails hunting on the sea.

Unlike its ancestors, the wooden belly of the Shenxing Taipo was opened on the surface of the sea, revealing a small platform inside, on which more than a dozen staff members were working nervously and busily.

Those are all professional teams from China, and at the moment they look serious, shuttling through a variety of high-tech instruments, comparing various parameters and data.

Song Wenbin thought to himself that if someone came to see this, they would definitely be startled by the black technology under the ancient appearance of the Shenxing Taibao, but fortunately, it was early enough, this atoll was far enough from the shore, and the Sanbao not far away could also play a warning role. As long as they can resolve the fight quickly, they may be able to avoid the risk of being discovered.

"Brother Song."

Sutina called him from the kayak.

The two colleagues had already prepared the kayak, and without too many words, Song Wenbin got on the boat, and the three of them took the kayak to the platform on the belly of the Shenxing Taibao.

At this moment, the director has already communicated with the professional team on the platform, due to the difficulty of this dive, the accompanying photographer is no longer able to follow them, and all the shooting can only be completed by their own cameras.

Song Wenbin stood on the platform, silently changing into a wetsuit, this time at a depth far greater than before, and their wetsuit also changed from an ordinary wetsuit to a full wetsuit with a buoyancy adjustment device, with a thick weight on the wetsuit, as well as a pressure gauge, depth gauge, dive timer and compass.

After changing clothes, they sat on the platform and were pushed into the water along with the platform.

But this is not the time to dive.

Song Wenbin sat on the platform, and the ship's doctor from the Shenxing Taibao came over to measure Song Wenbin and Huo Yu's blood pressure and heart rate, and after confirming that it was correct, someone on the side handed the special breathing mask to Song Wenbin and Huo Yu.

The respirator mask is topped with a yellow hose attached to the slender metal bottle in the belly of the cabin.

The two of them had practiced a few times when they were in China, and they would bite the breathing valve in the mask with ease, and gasp deeply and steadily.

These inhaled gases are not normal air, but helium oxygen, which is made up of helium and oxygen.

Since the composition of ordinary air is 21% oxygen and 78% nitrogen, but under the huge pressure of the deep sea, the excess nitrogen in the air will be integrated into the body and cannot be excreted in time, which will cause nitrogen intoxication.

Nitrogenia itself does not cause harm to people, but the pressure of the deep sea is very deadly, and nitrogenation causes different reactions in everyone, some people will be sluggish, and some people will simply be severely comatose and lose their functions. This is extremely dangerous in the deep sea.

Therefore, when diving in the range of 30 meters to 100 meters, Song Wenbin must inhale helium and oxygen rationed by the professional team to remove nitrogen from his body to complete the deep-water operation.

On the one hand, high-pressure helium helps him adapt to the pressure of the deep sea, on the other hand, helium has low solubility in the blood, which does not cause discomfort, and of course, helium can also reduce the decompression time and allow the diver to return to the surface faster.

Although there are many advantages, the degree of professionalism and difficulty of this technology is far beyond ordinary diving, and even the concentration of helium and oxygen they use will vary depending on the water pressure, but the specific ratio Song Wenbin does not know, he is only responsible for diving to find lost cultural relics, nothing more.

While Song Wenbin and Huo Yu were sitting on the platform to inhale helium and oxygen, the doctors accompanying the ship attached a lot of small electronic components to Song Wenbin and Huo Yu's bodies, just like the doctors in the hospital ward put on the patients.

In this way, all kinds of parameters of his body will be uploaded to the computer of the Shenxing Taibao platform in real time.

After attaching the components, the doctor advised, "You can only dive 70 meters, understand?" Be sure to end the dive and return to the shallow water before the air pressure is halved, ok? ”

Song Wenbin and Huo Yu nodded and made an OK gesture.

This is the first time Sutina has seen such a precious dive, the more the doctor does, the more frightened she feels, although helium and oxygen assist, but after all, it is the deep sea, in the deep sea, every ten meters will increase the pressure of one atmosphere, seventy meters is seven atmospheres, which is equivalent to the whole body to bear more than 100 tons of water pressure, the difficulty of which can be imagined.

She held the notebook, gnawed her nails with a pale face, and kept asking the accompanying doctor if her colleagues would have an accident, but in the face of the unknown of the deep sea, the doctor could only give silence.

After ten minutes of oxygen inhalation, Song Wenbin and Huo Yu's bodies were already filled with helium and oxygen.

The doctor removed the respirator mask and handed them the cylinder filled with helium and oxygen. Seeing Song Wenbin and Huo Yu carrying the gas cylinders, Su Tina couldn't restrain her nervousness anymore, and said loudly: "Pay attention to safety!" If it doesn't work, we'll come back. If the cultural relics are gone, they are gone, and life is still important. ”

Song Wenbin looked at Su Tina's nervous appearance, smiled, and opened his mouth: "Quack." ”

Huo Yu also opened his mouth and made a duck-like call, "Quack." ”

Due to the large amount of helium they breathed, their voices had changed at the moment, becoming very sharp and eerie.

Sutina was stunned for a moment, and then stomped her feet anxiously: "You still have the heart to joke, I said it, did you hear it?" ”

"I don't know who said before that they would kill themselves if they couldn't find the treasure chest." Song Wenbin chuckled.

"Oops!"

Sutina was about to cry in a hurry, she said with red eyes: "Do you know, if you can't do it, you have to give up!" ”

"Alright, alright, we know."

Huo Yu said in a strange voice, and after speaking, she hugged Su Tina: "Help us watch well, don't miss something." ”

After speaking, she made a gesture to Song Wenbin.

Song Wenbin nodded.

The two grabbed their gear and jumped off the platform.

Enter the 70-meter deep sea.
