Knowing that the two team members were still underwater and had not gotten on the boat, Qin Haiyang's head "buzzed", and one of them almost fell into the sea, but Mordin was quick and helped him.

"Mr. Qin, how long can their oxygen last? Hans asked eagerly.

"About three and a half hours. Qin Haiyang calmed down: "But depending on the use of individuals, if the dive is not deep, it can take a little longer, but it will not exceed 4 hours." ”

"That's very urgent, the two of them must have encountered some danger underwater, and we have to call for help immediately to the water rescue center. ”

Qin Haiyang nodded in agreement, Hans made an "SOS" gesture towards the cockpit, and his wife Rowling immediately understood what he meant, and immediately turned on the distress channel and sent out a distress signal.

"We should start a search and rescue immediately. Qin Haiyang had completely calmed down at this time: "Hans, I suggest that we first determine the location where they disappeared last, and then we will drive the ship to that point, and then follow the route they may move to carry out a fan search." ”

"Okay, when we get to the location, I suggest forming 3 or 4 search teams to split up. Hans glanced at Mordin and Yan Ran as he spoke.

"Okay! The yacht will start immediately!"

According to the positioning information displayed on the surveillance screen, the yacht drove at full speed towards the last spot on the water that Bai Na and the others had been located before they disappeared.

"Yan Ran, please go and wake up the team members in the cabin immediately and let them bring their equipment to the deck. Qin Haiyang finished instructing Yan Ran, and then asked Mo Ding: "Mo Ding, will you participate in the underwater search in a while?" We are mainly at a depth of about 5 meters from the water surface, searching for the sonar positioning information they carry, if you feel that you are not sure about night diving, don't force yourself to enter the water." ”

"I'm fine!" replied Mordin, decisively.

Although he has not yet been trained in night diving, the situation is urgent and saving people is important. In addition, he only dives at a depth of 5 meters, which does not involve the complex diving environment in the deep water area, so he thinks there should not be much of a problem.

"Hans, do you think Mordin can go into the water?" Qin Haiyang also wanted to ask the coach's opinion.

"I think if there is a veteran player in the lead, there should be no problem. Hans said after a moment's hesitation.

"Okay, then Mordin will also go and prepare. ”

"Okay!" Mordin turned and entered the cabin, and Qin Haiyang and Hans also began to prepare their diving equipment.

After a while, the team members appeared on the deck again in diving suits, and Mordin and Yan Ran also appeared on the deck together.

"Yan Ran, don't you go into the water, right?" Qin Haiyang frowned.

"No! Mordin can go down, and so can I. Yan Ran said resolutely.

"Forget it, don't fight, Yan Ran will follow me and promise to bring her back safely. Seeing her resolute attitude, Hans was afraid that he would delay time by arguing with Qin Haiyang, so he hurriedly proposed a solution.

"Okay, then Mordin is with me, Mei Qing and Xu Zhicheng can't go into the water anymore, you take a kayak to search on the water, and Lin Juan stays on the boat to assist Rowling in sonar detection and response. Qin Haiyang immediately grouped the players, and the team members had no opinions.

After analyzing it just now, Hans and Qin Haiyang believed that based on the location where Bai Na disappeared last, and based on the speed and time of their diving, it was calculated that the range of the two people was unlikely to exceed 2 kilometers of sea area, and the most likely chance to find them was to search in the direction they traveled before. Therefore, Qin Haiyang divided the search into 4 groups: Qin Haiyang and Hans led two groups of team members to dive 5 meters underwater to search, and one group of team members were very tired from diving before and it was not suitable to enter the water again, so they let them take the kayak carried behind the yacht to search on the water. Finally, the yacht turns on the underwater sonar search system and travels on the surface of the sea so that they can form a fan-shaped search area.

And once the two people were not found after the search on the 2-kilometer line, they turned around and searched again in the reverse sector.

Among them, the search task of the yacht is the heaviest, because it is fast and has strong sonar equipment capabilities, and will undertake more than half of the search area.

Seven minutes had passed since the yacht approached the target, when Rowling sent a message saying that the plane from the Water Rescue Center had taken off and would take about half an hour to reach the area. In addition, two diving teams in the nearby waters received a distress signal and were approaching, but it would take at least half an hour to arrive here.

Alas, it was too late, and when they arrived in half an hour, there might only be two corpses fished up at that time, Qin Haiyang sighed in his heart.

The yacht soon arrived at the designated place, Qin Haiyang was the first to jump into the water, Mordin jumped down after him, then Hans and Yan Ran also jumped into the water, Mei Qing and Xu Zhicheng's kayaks also went into the water, and 4 search and rescue teams approached in 4 directions at the same time.

After Mordin jumped into the water, the cold sea water made him feel excited, he calmed down, and found that Qin Haiyang had already swam almost 20 meters in front, he understood Qin Haiyang's urgency at this time, so he didn't care about him, paddled his legs hard, and swam closely behind Qin Haiyang.

The water was 5 meters below the water, and the beam of the searchlight above only shone about 10 meters before it became very faint. Mordin holds a navigator in his left hand and a sonar in his right, his eyes fixed on the signals that may appear on the screen.

Qin Haiyang turned his head and saw Mo Ding following him closely, he was a little surprised, he didn't expect that this novice's speed was quite fast and he could keep up with him, so he sped up again.

Mo Ding, who was following behind, couldn't help frowning, he was not afraid that he would not be able to keep up with Qin Haiyang, but he was worried that Qin Haiyang's desperate diving speed and not paying attention to the balanced distribution of physical strength would not last long and something might happen.

Sure enough, after only 5 minutes, Qin Haiyang's speed suddenly slowed down, and he made an upward movement with his thumb, and Mordin followed him to the surface.

Qin Haiyang took off the respirator.

"My leg cramped suddenly!" he said with a painful face, "Maybe I didn't warm up well, and I encountered cold water muscle spasms, so I need to deal with it quickly." Can you wait here for me a while?"

"I'll go on my own, if you can handle it and catch up. ”

"Can you do it alone?"

"No problem, I'll be careful. ”

"Alas, there is not much time, so I have to take some risks, and remember to put rescue bombs when in danger. ”

"Got it!" Mordin said, turning over and diving into the water to move on.

Without Qin Haiyang's restraint, Mo Ding used all his strength, fought hard to hit the water, and rushed forward like an arrow.

His leg muscles are 5 times stronger than ordinary people, and his endurance is far better than before, so he swam forward with his flippers, and his speed suddenly increased, even exceeding the swimming speed of ordinary fish.

Swimming 1 kilometer like this, Mordin suddenly noticed that the sonar had reacted, and he quickly stopped to observe, but the signal suddenly disappeared again.

Mordin judged that Bai Na and the others might be nearby, and hurriedly cruised along the surrounding area, and the sonar signal was intermittent, and it was impossible to determine the exact location of the sound source.

The sea conditions and terrain in this area are very complicated, if Bai Na is sunk on the bottom of the sea, the sound waves emitted by the sonar instrument they carry with them will be reflected and refracted by the seabed, and then diffracted by marine fish and plants, and the sound propagation will be greatly affected, and it will be impossible to determine the location of the sound in a short time.

But time is already of the essence, and in a few minutes Bai Na and their oxygen may run out.

What to do?

Only when diving down, there is less disturbance when approaching the seabed.

But a rookie who has never had night diving experience is at a huge risk at this time, and he is still alone.

"I can't care about that much!" Mordin gritted his teeth, manipulated the buoyancy adjustment device, and a fierce man stabbed down.

When he reached the bottom of the sea, Mordin found that it was a trench more than 30 meters deep, and sure enough, the sonar signal received here was unusually clear.

"They should be not far from this trench. Mordin judged by the direction of the trench. With all his strength, he swam swiftly along the trench.

The trench is overgrown with many coarse brown algae marine plants, like a huge underwater forest, blocking Mordin's path one by one. Mordin deftly avoided these leafy algae plants, and his speed did not decrease at all, because the sonar signal was getting stronger and stronger, and he knew that Bai Na and they were not far ahead.

A few dozen meters further, Mordin's searchlight column found Bai Na and Wang Xian. The two of them lay motionless in the mud at the bottom of the trench, while a huge strange fish swam beside them.

"Electric ray!" Mordin recognized at a glance the strange fish that was 2 meters long. The strange fish had a wide head, and its eyes on both sides were firmly fixed on Bai Na and Wang Xian who were lying in the mud, and when it noticed that Wang Xian's legs were twitching slightly, it rushed over and discharged at Wang Xian. Then they swam around him like a demonstrator, ready to teach the human a little more lesson.

Bai Na, who was not far away, remained motionless, and was not attacked by the electric ray for the time being.

"Oh no! This electric ray seems to be consumed by them, as long as it doesn't leave, it will rush over by itself, and it will only be cannon fodder. Mordin was secretly anxious: "Only by killing it first can you save people." ”

He only has an anti-shark knife in his hand as a weapon, and the weapon of the electric ray is a high-voltage electric current, and before he can get close to it, the possibility of being electrocuted is very high. What to do?

Suddenly he thought of a weapon that would definitely work.

He removed the embroidery needle from his waist, and with a whim, it turned into a long sword three feet long and as wide as a palm. Mordin aimed the tip of his sword at the electric ray, and with a movement of his mind, the virtual sword was a phantom, and the electric ray was instantly pierced.

The electric ray struggled violently a few times, and after a while it was lying on its belly to the sky and lying in the mud.

Mordin quickly swam over and saw that both of them were already unconscious.

He checked the gas cylinders of the two of them, and found that Wang Xian's barometer pointer had pointed to the zero scale, and Bai Na's cylinder still had a little remaining gas, so he decided to save Wang Xian first. Mo Ding put away his sword, wrapped his hands, picked up Wang Xian, quickly swam to the water, and soon reached the sea, he pulled out the respirator that Wang Xian clenched in his mouth, after Wang Xian's convulsions, he began to have a faint spontaneous breathing, Mo Ding began to put his mind at ease, wanted to put Wang Xian in place, and continued to save Bai Na.
