The Gulf of Tonkin is a semi-enclosed bay located in the northwest of the South China Sea. It is bordered by Leizhou Peninsula and Qiongya Island in the east, Guixi in the north, and Annan in the west, and is connected with the Qiongzhou Strait and the South China Sea.

As a major passage to the sea in the southwest, there were many merchant ships coming and going here in the early days. Its unique geographical location highlights the importance of its strategic location, and in the early years, in order to compete for jurisdiction in this area, China even carried out naval defense battles for this purpose.

Despite current agreements with neighbouring countries on maritime sovereignty, disputes over the waters persist from time to time. In particular, fishermen who have been engaged in fishing in this area for many years often come into conflict with fishing vessels from other countries.

In order to ensure the safety of domestic fishing vessels, the domestic maritime surveillance department has also strengthened the supervision of this sea area. But after all, the power of the sea guard is limited, and it is impossible to keep an eye on this sea area every day. As a result, there are occasional fishing vessels that cross the border.

Xu Haibao, who chartered a medium-sized yacht this time, rested in Fangcheng for one night, and the next day everyone boarded the ship and went to sea one after another. Regarding the purpose of Xu Haibao and his entourage going to sea, many people think that they are going to the sea for a leisurely time.

But in fact, as early as before Xu Haibao and his entourage boarded the ship, a large number of advanced diving equipment were sent to the yacht one after another. Next, Xu Haibao will lead the diving team to conduct underwater diving training in the open sea of Beibu Gulf or in China.

Compared with the previous diving training in Xiangjiang and Fulin Island, Xu Haibao asked the diving team members to try out the diving training, which was more free-diving. And this time carrying diving equipment is to let everyone find the feeling of deep diving in a deeper place.

At least Xu Haibao hopes that when the salvage ship goes to sea to carry out the salvage mission, the members of the diving team can regain the diving feeling of their early years in the army. Whether it can improve compared to the troops, it is quite important to say that it may not be able to adapt to deep-sea diving.

As a professional diver, Xu Haibao and the members of the diving team know it. If they are in good shape, they are really not suitable for deep diving missions. Then their best option is to move to another position.

The yacht sailed for nearly three hours, looking at the vast sea area that he had arrived, Xu Haibao also said in a timely manner: "Rudder, stop here for a while, we are going to go to the sea for a test dive." The depth of the water here should be about 100 meters!"

"Yes, understood!"

When the yacht began to slow down and finally stopped moving forward, looking at the other divers who were about to go to sea, Xu Haibao said with a serious expression: "You guys put on diving equipment first, and I'll go down to explore the road first to see what the situation is below."

Before the test dive, I would like to stress again that this is just a routine training session, all to test your diving skills and physical recovery. As soon as you feel unwell, you have to stop diving, you know?"

"Understood!"

Although most of the members of the diving team feel that their bodies have recovered a lot. But they also know in their hearts whether they are really all recovered, and it depends on whether they will feel extremely uncomfortable when they go to the deep water.

If this is the case, it is the wisest decision to stop diving. If they force their way down, they are afraid that they will be injured again. The situation is dangerous and can also endanger their lives.

After explaining the precautions before going to the sea, as the leader of the diving group, You Guangwei also said directly: "Swordfish, don't you go into the water without equipment?

"It's okay! I know how good I am in freediving. I'll pull the measuring rope down later, and you'll be looking at the depth on it. As for my safety, you don't have to worry. When you start diving, you have to take it easy. ”

"Okay, then be careful yourself!"

Regarding how strong Xu Haibao's free diving is, You Guangwei and everyone on the yacht are very admired. Even many divers know that even if they carry diving equipment, they may not dare to try the depth of Xu Haibao's freediving.

Before going into the water, Xu Haibao also instructed Zhao Ji: "After I get into the water, you pay attention to the surrounding situation." If you notice an unknown vessel approaching, be sure to warn in advance. Pull the rope a few times and I'll get up as soon as I can!"

"Okay, I got it!"

As a member of the security team, Zhao Ji and several team members were equipped with a telescope. When the diving group goes to sea for a trial dive, they need to be alert to the surrounding situation. If a vessel is spotted approaching, the diver must be notified immediately to ascend.

This sea test dive is also a group run-in training. At least for Xu Haibao, he hopes that after the delivery of the salvage ship in the future, the team can form a certain tacit cooperation and perform their duties to ensure the smooth completion of the salvage task.

After turning over and falling into the water, Xu Haibao held the measuring rope and dived quickly. Looking at the rapid elongation of the measuring rope, everyone staying on the yacht also felt that Xu Haibao's diving speed was very high, as if they did not feel the pressure of the deep sea.

So much so that some members of the diving team saw this scene and sighed: "Jellyfish, seeing the swordfish diving at this speed, I always feel that he performs a deep dive under the sea, as if he can't feel the water pressure at all." I don't know how he did it!"

"Okay! If the swordfish doesn't have this ability, will he dare to pull up such a team? In the future, what our diving team has to do is to cooperate with the swordfish in the search for the seabed. If he really wants to salvage the wreck, he can't do it alone.

Remember what the swordfish said before, no one should be too reluctant, and they must do what they can. Even if we can't get back to the best state in the army this time, at least we have to know it in our own hearts. You should know that Swordfish is very safety-conscious!"

As Xu Haibao dived to the bottom of the sea, looking at the scene in the sea, he also felt that the sea water here seemed to be very clean, but in fact, the sight was not too optimistic. Fortunately, in this case, there is not much pressure on Xu Haibao.

Taking out a diving flashlight, Xu Haibao began to look at the situation on the bottom of the sea. In his personal opinion, the strength of the swells at the bottom of the sea is not very strong now. In this way, it is still more suitable for deep-sea diving missions.

On the other hand, the people who were staying on the boat at the moment watched the measuring rope finally stop pulling, and the scale on it clearly informed them that the sea depth at the location of the yacht was nearly 100 meters. At this depth, the risk is still small.

However, as professional divers, such a depth is not too challenging for them. In the future, if they really want to go to the sea to carry out exploration and search missions, they need to dive deeper, but I am afraid that it will be deeper than this.

Just as the members of the diving team put on their diving equipment, You Guangwei, as the team leader, also said in a timely manner: "Work in pairs, alternately cooperate and start diving." If there is a situation, gesturing in time, don't force it, remember it?"

"Remember!"

"Okay!

In the end, Wang Yuzhu, who had been recuperating for the longest time and was in relatively light condition, and another team member, as the first group of diving team members, began to dive underwater. In this process, the two were never too far apart.

Xu Haibao, who stayed underwater, also paid attention to the situation on the water surface. After checking the vicinity and confirming that there were no unexpected findings, I floated up to the middle of the water and paid attention to the test dive of each member of the diving team.

Wang Yuzhu, who was the first to enter the water, saw Xu Haibao waiting in the middle of the road, and also made a timely gesture: "It's safe! You can continue to dive! What is the underwater situation?"

"It's calm!You can continue!Stay safe!"

After both sides passed the message in sign language, Wang Yuzhu and another team member continued to dive downward. Looking at the measuring rope that was not far away, both of them knew that the depth they were at at the moment was already more than fifty meters.

At this point, the pressure increases with every meter of diving. Fortunately, with Xu Haibao watching from the sidelines, they don't have to worry about any accidents. At such times, their attention is undoubtedly more focused.

Six professional divers have been recruited, and after diving in pairs, Wang Yuzhu and another team member in the first group have been recruited. finally stepped to the bottom of the sea safely, looking at Xu Haibao's gestures, the two also responded in a timely manner.

"How does it feel?"

"It's okay! It's just that the pressure on my body is still very high!"

Knowing that their bodies are currently in the stage of rehabilitation and conditioning, they must inform Xu Haibao of the most real situation so that they can determine whether to continue conditioning in the next step. But when they dived to this depth, they were still quite happy.

Although they did not break their own best level in the army, they could dive nearly 100 meters deep, and ordinary people did not dare to try it easily even if they carried oxygen cylinders. Although the body feels uncomfortable, this discomfort is a natural reaction.

With the training they have undergone, this level of discomfort is acceptable. When they are discharged from the army, they will already feel very uncomfortable when they dive to this depth. But now, this uncomfortable feeling has lessened a lot.

When the second group of people dived deep and one of the team members reached the 80-meter position, he felt very unwell, and after making the gesture of 'need to float', Xu Haibao quickly rushed to his side.

Gesturing: "Stop diving, start floating!"

Although I feel a little regretful, this team member has the shortest time to recuperate, and I am afraid that his body has not yet recovered to the best condition. It's very rare to be able to dive to this location. If it wasn't too uncomfortable, I believe the team members wouldn't give up halfway.

Accompanying the team member to slowly float up, Xu Haibao specially explained to Wang Yuzhu and asked him to pay attention to the safety of the other two. Wait for a walk on the bottom of the sea, and he will continue to accompany him later.

You Guangwei, who finally dived, looked at Xu Haibao and another team member who suddenly floated, and quickly realized that the team member's body was afraid that he had not fully recovered. Fortunately, with Xu Haibao on the side, their lives are not in danger.

After receiving Xu Haibao's instruction to 'continue diving', You Guangwei and another team member also began to continue their deep-sea test dives. In the final analysis, this sea test dive is more to test their physical recovery.

As You Guangwei said earlier, there is no need to be too reluctant at this time. If you really want to hurt your body again, it will be more troublesome to recuperate. Do what you can, and there's nothing to be ashamed of in this situation.

After all, before being summoned by Xu Haibao, they were all people who retired due to illness. It's quite remarkable to dare to try to continue the deep diving mission now. Some things, too anxious are easy to do bad things!
