The others shook their heads and said, "It shouldn't be possible there, no one can dive to such a deep seabed without diving equipment, let alone enter the cave alive." ”

Everyone thought it was impossible, but out of duty, they reported the situation to their boss.

When Xiang Chao and the others heard it, they also felt that it was unlikely, but he didn't dare to assert himself, so he still reported the situation to Luo Ning.

"Underwater Cave?!" Luo Ning listened, and his eyes, numb from pressure and exhaustion, suddenly had a hint of light: "No matter how small the possibility is, you can't give up! ”

"But the terrain of the submarine cave is complicated, and no one knows what is going on there, so it is too risky to send people down rashly. Neither the search and rescue team nor the fishermen could agree to go down and take the risk. Xiang Chao reminded.

"Unless there is a way to determine that Ji Jingyan is down there, it will be difficult for us to ask them to go down. Wen Yuzhe was also distressed.

"They don't go, I'll go!" Luo Ning stood up abruptly and said resolutely.

Xiang Chao hurriedly stopped her: "Don't be impulsive! Even professionals don't dare to go down easily, you layman can only be sent to death if you go down!"

"I don't care, no one goes, I'll go, anyway, I can't let go of any possibility. Luo Ning said stubbornly.

Xiang Chao said helplessly: "Then you give us a little more time to think of a way, and see if we can find a way to confirm that Ji Jingyan is not down there first?"

"Okay, I'll give you ten minutes, I'll go and feed Mu Ning and set off. Luo Ning left the unquestioning order and turned to leave the cockpit.

Ten minutes later, Luo Ning appeared on the deck, and Tang Jia behind him was holding two sets of diving equipment in his hands.

Xiang Chao hurriedly ran out of the cockpit: "Luo Ning, you wait, we think of a way, maybe we can try." ”

"What's the solution?" Luo Ning asked eagerly.

"Xiao Yan took some gadgets from us before, and he should take them with him. Among them was a miniature signal transmitter that he should be carrying. This transmitter can work for 72 hours when the power is turned on, and the signal reception range can reach 5 kilometers. I have informed all the search and rescue vessels to turn on the receivers and may receive the signal. Xiang Chao said.

Luo Ning asked: "Is this signal transmitter waterproof? If Jing Yan is on the bottom of the sea, can the signal penetrate the seawater and reach the surface of the sea?"

"The waterproof performance is average, but if you soak it in water for more than 10 minutes, it will be damaged. Now I can only hope that the place where Xiaoyan is hiding is waterproof enough. Xiang Chao replied weakly, not daring to look at Luo Ning. "If Xiao Yan is really at the bottom of the sea, the signal acceptance range is probably only one kilometer at most. ”

This is a dead horse as a live horse doctor!

"I see. Luo Ning said calmly, "You help me prepare a signal receiver, wrap it in waterproof material, and I'll try it near the cave." ”

Xiang Chao saw that she still wanted to go into the water, and volunteered: "Let's go with me, I am familiar with operating the receiver, and I am more suitable than you." ”

This reason is strong enough, Luo Ning didn't fight anymore, and advised: "Then you must be careful, try to get as close as possible, and don't miss it." ”

Xiang Chao nodded solemnly, put on his diving equipment, took a signal receiver tightly wrapped in a transparent waterproof bag, and went into the water.

According to the fishermen's report, the entrance to the submarine cave is only more than 100 meters deep according to the sea surface, but the cave is narrow and winding, and the terrain is complicated, so he does not dare to enter it.

Xiang Chao and three divers from the professional rescue team came to the entrance of the cave, turned on the signal receiver, and waited for a few minutes without any response.

Xiang Chao signaled to go to the cave, the divers took out a bundle of long ropes prepared, leaving one person at the entrance of the cave, and the others buckled the rope with the safety buckle around their waists and swam to the cave in turn.

The cave was winding, there were several forks, they swam in it for more than ten minutes, they obviously felt the pressure increased, Xiang Chao looked at the pressure gauge on his wrist, and found that the depth had become about two hundred meters.

It turns out that the cave is winding downward.

After swimming for a while, the rope of several hundred meters had reached the end, and they could not go any further. The lead diver gestured for everyone to go back.

Xiang Chao had no choice but to give up, and when he turned around and swam back, the light of the receiver suddenly flashed, and Xiang Chao suddenly stopped and stared at the receiver.

No reaction at all!

Could it be his delusion?

He thought about it for a moment and decided to take a closer look. But the rope was already at an end, and despite the resistance of several divers, he resolutely untied the rope and continued to swim forward.

The two divers reluctantly communicated with gestures, one of them was not at ease and went with him, and the other stayed where he was.

After going down for another ten meters, fortunately there was no fork in the road in this section, and the receiver's light flashed again, and it flashed quite quickly, Xiang Chao immediately confirmed that this was the signal sent by their signal transmitter.

This shows that Ji Jingyan is indeed in the depths of this cave!

Xiang Chao was ecstatic, and the divers behind him kept gesticulating to tell him the good news, and then subconsciously rushed forward, hoping to go down immediately to find Ji Jingyan.

Seeing this, the diver behind him couldn't care about anything else, and rushed up at an accelerated pace to grab Xiang Chao's foot and drag him back.

Xiang Chao's brain was hot just now, and after being dragged back, he calmed down, knowing that he might not be able to find Ji Jingyan if he went down rashly, but might put himself in danger.

He repeatedly assured himself that he would not be impulsive again, and the diver let him go, and the two of them struggled to turn around and swim back in the narrow cave.

When he arrived at the rope, Xiang Chao kept an eye on it, tied the rope to a protruding stone, and marked it along the way.

When I went back, the speed was much faster, and it only took ten minutes to get out of the cave, and the four of them returned to the boat together.

Xiang Chao took off his oxygen mask, didn't care about panting, and immediately conveyed the good news to Luo Ning, who was guarding the deck: "Received the signal, Xiao, Xiao Yan may really be in that cave-"

"Really?!" The great joy was like a huge wave surging and hitting her nerves. Luo Ning took a step forward nervously, all her thoughts were highly concentrated at the moment, for fear that what she had just heard was just an illusion.

When she clearly saw Xiang Chao's sure eyes, she didn't have time to taste the joy, her mind suddenly went blank, her body tilted, and she fell to the deck.

Tang Jiayan quickly held her up, pinched her hard, and it took a while for Luo Ning to recover from it, and the first thing he said after waking up was: "Quickly equip me, I'm going down to find Jing Yan." ”

"No, you're too weak, there's too much pressure down there, you can't stand it. Xiang Chao and Tang Jia opposed at the same time.
