After the test is successful.

Li Yonglong went to rest first because he was too old, while the other staff members did not move and stared nervously.

Yang Zhengyu and Jin Mao were drinking tea and chatting.

Reluctantly use tea to refresh yourself.

The two of them chatted until midnight. The more they talked, the more sleepy they became and they yawned all the time.

Shandong is in full swing, and the roar of water pumps is constant.

About an hour later, data appeared on the scene.

The detection staff came over to look for Mr. Jin with their notebooks in hand.

"Judging from the data we got and the sonar detection data, there is a very deep space inside. After about 20 meters past the entrance of the cave, the space becomes very wide."

"What do you mean by saying that? Why don't I understand you at all?"

Not only did Mr. Jin not understand it, but Yang Zhengyu didn’t understand it very well.

"That is to say, it has been initially ruled out that there are ancient tombs and river beds."

This makes everyone feel strange.

"Is it possible that this section is connected to the river bed?"

Both staff members shook their heads together. For professionals like them, the matter was very clear.

"This is impossible. There can be no river bed with such fast currents so close to the surface."

The opinions of professionals are usually very clear. As long as they say no, there is a high probability that there is no.

Mr. Jin was stunned: "Then let's send someone in to take a look. This is beyond our imagination."

It seems that things are not as simple as several people planned before.

Sending people in now is also part of their plan.

After detection, if it is safe inside, you can send people to dive in.

By this time, the people transporting the diving suits had also arrived.

Old Huang, who was yawning profusely, brought them over.

Introduced to them, "These three are from our salvage team here. They have all worked on the coast and are of very high standard. We are the only ones in the nearby cities that have this kind of configuration."

Mr. Jin said: "Very good, then you can go in."

The staff of these three salvage teams are also very professional.

They watched the scene and listened to the opinions of other staff.

The surveyors drew a drawing based on the survey they made.

The staff of the two salvage teams talked over the drawings with ease.

"Then let's go in through this hole."

"Before going in, we will do a preliminary inspection of the surrounding area."

"First of all, we need to take a look at the hole after entering it. Is there any danger inside?"

"We also need to take a look inside, what does the waterway look like?"

Mr. Jin said: "You should also pay special attention to the water flowing out of it. Although it seems harmless at the moment, you should be more careful. We are not sure yet whether there are plankton in the water."

The salvage team members were all very professional people, and they nodded.

Yang Zhengyu said: "You'd better go in in two groups. Send one person in first to explore the truth."

The two members of the salvage team smiled and nodded when they heard this: "Of course we have a plan for this, don't worry."

Mr. Jin said: "Okay, let's start now."

The three salvage team members couldn't wait for a long time. After hearing this, they said goodbye to everyone and started to prepare.

Judging from their intentions, they don’t seem to like having other people around them.

When they are ready, they dress like poachers.

Carrying a huge oxygen tank behind him.

The feet are like frogs.

Everyone came to the entrance of the cave.

Before, the entrance of this cave seemed to be a very small hole, but after the rain and the work of workers, it has turned into a very large entrance.

The soil next to it was washed away by the flow of underground rivers.

It feels like the cave is about to be emptied. Judging from the situation, this small mountain bag will not be able to hold on for a few more days.

Yang Zhengyu said: "You must be especially careful when going in. The water flow in the underground river is complicated."

I was interrupted before I finished speaking.

"Now that we know it, you don't need to worry about it. We can solve this ourselves."

Yang Zhengyu then stopped talking.

The staff set up a ladder inside the cave.

There are also bright lights hanging on the four walls inside the cave.

At this time, the rushing water is like a waterfall in the mountains, whizzing down from the hole at the top.

A heavily armed diver climbed up the ladder and gradually approached the entrance of the cave.

He first stretched out his hand to test the impact of the saliva flowing from the hole.

"The water flow is not particularly strong, you can try to get in."

He turned around and told the others.

Everyone here gave him a thumbs up.

This person is wearing goggles and a hood.

Even so, everyone saw him take a deep breath.

Then he fell headlong into the deep pit.

Originally, he had nothing to do.

But suddenly it seemed that the current was getting heavier.

As soon as the firstborn child was buried in the water, he was washed out.

The people holding the ladder below swayed a few times and were almost knocked down.

His two companions quickly stepped forward to help him up.

"How's it going? Are you okay?"

The man hesitated as if he wanted to speak, but no one heard his voice.

Yang Zhengyu's heart was instantly filled with an ominous premonition.

Things don't seem that simple.

At this time, his two companions had already taken off his diving glasses.

"It's not good, call an ambulance quickly."

Everyone came forward and took a closer look, and it seemed that his face had been hit hard by a sledgehammer.

The whole face was bruised and bloody, beyond recognition.

Mr. Jin said calmly: "Be careful, don't move him yet. I don't know if there are any injuries on other parts of his body."

Things are a little big now.

Lao Huang also touched his head, feeling a little at a loss.

Mr. Jin scolded him, "Why are you still standing there? Why don't you arrange for an ambulance to come quickly?"

"Yes, yes, I will arrange it now."

Before this incident, no one thought that medical staff would be deployed at the scene.

Before, everyone thought it was just a very routine detection.

I didn't expect it to have such a sinister side.

Mr. Jin said: "It seems that we cannot underestimate this matter, we must pay 12 points of attention."

The other two people in diving suits were a little at a loss.

The situation where their companions were injured played out repeatedly in their minds.

Now let them in, and they won’t dare.

Li Yonglong said: "How about this? I will contact an old classmate of mine tomorrow morning. He is doing ocean exploration at a coastal university in the south."

"They have ocean detection equipment there. We asked him to come over and use the equipment to detect it first."

"What do you think?"

What Li Yonglong said is of course the most appropriate method now.
