When Poplar Iron Bull first heard about the "Tomb under the Sea", he was very surprised, thinking about how the tomb could be built on the bottom of the sea?

Later, after listening to Ding Sicheng's explanation, I learned that the so-called submarine tomb was not built on the bottom of the sea, but a super-large wooden ship was built first, and then the tomb was built on the wooden boat.

After that, the wooden boat was dragged to the selected sea area, and the bottom of the ship was chiseled, causing the wooden boat to sink with the tomb.

Among them, it is not difficult to build a ship and build a tomb, but the difficulty is that in the process of sinking the wooden ship with the tomb, it can not tilt and collapse, but also withstand the strong water pressure. If the walls of the tomb are not strong enough, and the sea water pours into the tomb, all the work done will be wasted.

Therefore, from ancient times to the present, there are very few submarine tombs that have been used, and the submarine tombs that have been discovered are even more unique.

What's even more surprising is that both salvage teams believe that what they found was the tomb of the great pirate Redbeard nearly a thousand years ago, and even the tomb maps they found in different ways and in different locations were contained in the same delicately sealed metal boxes.

Why is there such a coincidence? How true can what Boss Kim say?

Poplar Tie Niu fell into deep thought, and Ding Sicheng was also silent for a long time.

Boss Jin knew that it was impossible for these three people to believe him easily, and said: "I know that there is no evidence, and that map was indeed destroyed by me, but I have personally gone to that place to explore before, if Master Chen refuses to believe it, you can go to that place with me to explore." Wait until Master Chen is sure that there is really a big undersea tomb down there, and then return this bag of antiques to me!"

Ding Sicheng smiled and said, "Aren't you afraid that if you really took us to the undersea tomb, we still won't return your treasures, but will kill you?"

"No!" Boss Jin immediately said, "I see people very accurately, Master Chen will never be such a faithless person......! I am sure that Master Chen is a member of the government, and even those vicious Vietnamese Master Chen will not kill, let alone kill me, a Chinese!"

Ding Sicheng didn't respond to this sentence, but Bai Yang couldn't help but speak: "Boss Wei, they have already determined that there is a tomb down here, if Master Jin really found another submarine tomb, then which one is the submarine tomb of Redbeard?

"I think it's weird too!" Boss Jin replied, "The mention of the delicately sealed metal box by the big boss of the front guard really startled me!, so I wondered, could it be ...... Of these two tombs, one is an empty tomb?"

"It shouldn't be possible to have an empty tomb!" Ding Sicheng said, "This submarine tomb is not a land tomb, just sinking the finished tomb to the bottom of the sea smoothly and steadily, and not letting it enter the sea, is already a very complicated and huge project! If you are not careful, the built tomb will be destroyed in the process of sinking into the water! So...... It's impossible to build an empty tomb and sink it to the bottom of the sea unharmed!"

Others also found it unlikely, so several fell silent again.

There was silence in the cabin, except for the faint sound of the waves crashing against the hull outside.

After a long time, Boss Jin opened his mouth and said: "Anyway, since the two maps are contained in the same delicate sealed metal box, it at least proves that the two tombs must be connected......! Redbeard is actually more than just a person, for example...... He has a twin brother? or...... There's a big tomb, the tomb of one of his good brothers?"

"It's possible what you said!" Ding Sicheng replied, "Otherwise, let's go to the sea to excavate the tomb here in the next few days, and then discuss the matter of the undersea tomb that Master Jin said......! This bag of antique relics will be talked about later!"

Boss Jin didn't dare to say more, and hurriedly said, "It's okay! In short, I believe that Master Chen will never treat me badly, and he will not ...... Let my brothers and companions who were killed by Vietnamese robbers die without a blind eye!"

He choked up again, and Ding Sicheng knew that his words had other meanings, so he didn't pay attention to them anymore.

As soon as it was dawn the next day, someone woke Ding Sicheng and the others up.

It happened that it was a very good day today, and a few people just ate a little food, and then packed up and prepared to go to the sea.

A core backbone of the salvage team named Sha Liang wants to follow him into the sea, this person is thin, but his hands and feet are much larger than ordinary people, it is said that when he gets to the water, his big hands and feet are more convenient to paddle the water.

In the words of Boss Wei, once this person goes to the sea, he is really like a fierce little shark. It just so happens that his surname is Sha, so he has a nickname, called "Flying Shark in the Waves".

In addition, there are three Ding Sicheng's "master and apprentice" who will go to the sea today, plus three Vietnamese and Jiang Peng.

As for the two Koreans, they are only responsible for finding the most suitable place to open the cave, but they will not follow them into the tomb.

The so-called most suitable place for opening a tomb refers to the place where the tomb is relatively weak, but the water pressure is low, which is naturally more important for two Korean experts who are familiar with water conservancy construction.

In fact, two South Korean experts have been here for two days and have basically identified the place where they can shovel and make holes, and the silt and floating sand in that place have been cleared.

Of course, if you want to shovel and make holes, you will not just let these experts who are invited to do it, in fact, when you go into the water today, you still have to further determine that the place designated by the two Korean experts is really okay with the shovel.

After all, the two Korean experts only have studied underwater architecture, but they have never dabbled in tomb architecture, and they dare not say that the place they designated is correct.

Boss Wei inevitably said a few kind words of "I have to work for you", and then a total of nine people sank into the water wearing diving suits and carrying air tanks on their backs.

This seabed is not very deep, after all, the deeper you go, the stronger the pressure of the sea, so it is necessary to ensure that the built tomb will not be squeezed into the water and be torn apart, and the selected shipwreck site cannot be too deep.

The depth of this sea area should be about 100 meters, and after reaching the bottom of the water, you can still vaguely see the situation at the bottom of the sea with the help of the light that penetrates the water.

The bottom of the sea was originally very flat, but it had a huge protrusion, which looked like a huge mound from a distance.

Dozens of small sand dunes were scattered around the mound, several of which had been washed away by the sea, revealing large square stone blocks inside.

In fact, at yesterday's dinner, the two Koreans had already mentioned these stone pillars.

Just because the ship that built the tomb must have been extremely large, these huge stone blocks could not only keep the ship stable in the designated sea area, but also prevent the tomb from tilting and collapsing in the process of digging through the bottom of the ship and sinking the tomb.

And around the huge mound, which was already covered with seagrass, and a large part of the lower part of the mound was buried by floating sand—

Of course, I also learned this from Koreans during dinner yesterday.

The group dived underwater, followed the two Koreans to the backlight of the mound, and suddenly found that a large gap had been dug in the sand next to the mound, revealing the outer wall of the mound buried by floating sand.

Regardless of the question, it can be seen that this gap is the place where South Korean experts have designated to dig holes with shovels.

Ding Sicheng, Jiang Peng, and the three Vietnamese first carefully surveyed the gap, and then circled the mound several times, and used the iron drills they brought down to continuously insert into the floating sand to explore.

The two of them did not bring an iron hammer down, but each brought a long javelin.

The two of them didn't dare to say that they were very familiar with the tombs on land, not to mention that the two of them were still seeing this submarine tomb for the first time, so the two of them went into the water this time and were mainly responsible for the protection work.

The salvage team originally had a very advanced water gun, but the poplar iron bull felt that the lethality of the water gun was limited, and it was not as fierce and flexible as the long javelin in his hand.

Fortunately, there were no accidents, and there were no ghosts and sharks that came out to infest, and the group stayed at the bottom of the sea for nearly an hour, until the air in the cylinder was almost exhausted before surfacing.

After that, a few people began to discuss where to start with the hole.

Jiang Peng had entered a submarine tomb, although the submarine tomb he entered was far less large than the tomb he saw today, but he was finally the only person with experience, and in his opinion, the direction designated by the two Koreans was not the best direction to open the hole.

The two Koreans immediately quarreled with Jiang Peng, saying that with their professional standards, it was impossible to make a mistake.

Boss Wei had a hard time making a decision, and asked Ding Sicheng to go with the three Vietnamese, but the three Vietnamese did not express their position, but Ding Sicheng expressed his support for Jiang Peng's opinion.

In the end, Boss Wei decided that Jiang Peng would re-designate a suitable location for opening a hole, and make a decision after the floating sand was cleared out.

The two Koreans were inevitably full of anger and refused to follow them into the sea, and the boss of Wei Da was not reluctant, and arranged a few salvage team members with good water characteristics to bring tools and follow down.

Others, including Ding Sicheng and Poplar Tieniu, re-entered the sea with compressed gas cylinders, and Jiang Peng designated a place, and the others began to use tools to clean up the aquatic weeds and floating sand around that place.

Unexpectedly, in the middle of cleaning, something suddenly came out of the sand and bit the thigh of a salvage team member who was shaving sand.

The salvage team's wetsuit was immediately bitten, and blood quickly spilled from the team's thighs.
