Since entering the sea, Dong Ren'an is like a different person, full of energy, swimming quickly in the water, swimming this way for a while, swimming that way for a while, moving sensitively and standardly, and he knows that he is a diving veteran at a glance.

Although Gao Fei has not dived much, but he has an excellent system, has a good coordination, can freely adjust his body in the water, no matter how Dong Ren'an tosses, can not open the distance between him and Gao Fei, after a few attempts, Dong Ren'an dispelled the idea of making small moves, he originally wanted to use his rich diving experience to get rid of Gao Fei and Liang Fuchen, now it seems that he is whimsical, in terms of diving experience and technology, Gao Fei is stronger than him.

Compared with Gao Fei and Dong Ren'an, Liang Fuchen's diving skills are very poor, he took a lot of effort to barely keep up with Gao Fei and Dong Ren'an, looking at Gao Fei and Dong Ren'an's relaxed appearance, Liang Fuchen felt very unhappy, and vowed to take more time to practice diving after going back, and strive to impress Dong Ren'an and Gao Fei next time.

After about an hour, Dong Ren'an suddenly stopped and pointed his finger downward.

Huh? Goofy looked down and saw a patch of silt down there, and he saw nothing but a few small fish playing in the mud.

Liang Fuchen was more anxious, and he didn't say hello, and rushed directly down, "Poof!" Liang Fuchen plunged into the mud, and it took a lot of effort to climb out, and his whole body was dirty, not to mention how embarrassed he was.

Seeing Liang Fuchen's embarrassed appearance, Dong Ren'an was very relieved, if it wasn't for the wrong occasion, he would definitely laugh a few times.

Liang Fuchen waved his fist at Dong Ren'an, and then pointed downward, probably asking where Dong Ren'an's ancient tomb was.

Dong Ren'an raised his middle finger at Liang Fuchen, and then slowly fell down.

Liang Fuchen is so angry in his heart, grandmother, do you dare to give me the middle finger? Okay, let's wait and see, and when we find the ancient tomb, see how I clean you up.

Dong Ren'an took out a metal stick the thickness of a little finger from his pocket, shook it slightly, and the metal stick suddenly became longer, from a few centimeters to more than a meter long.

Liang Fuchen looked at Dong Ren'an with wide eyes, and muttered secretly in his heart, when did Dong Ren'an get a metal rod? Can it be retracted freely? How much else is this kid hiding from me?

Dong Ren'an stabbed the elongated metal rod into the mud, and then began to beat, knocking east, knocking, knocking here, then knocking there, and he didn't know what he was doing.

Liang Fuchen wanted to go over and question, but was stopped by Gao Fei, since Dong Ren'an must have his intentions in doing this, let's not go over and bother.

"Boom!"

Dong Ren'an felt the metal stick poking at a hard object, his face suddenly became happy, he found it! This is it! Dong Ren'an put away the metal stick, then took out a small shovel from his backpack, and then began to frantically shovel out the mud, and soon, Dong Ren'an shoveled out a hole more than half a person high, "Bell!" The small shovel poked a hard object, in the end! Dong Ren'an turned around and beckoned to Gao Fei and Liang Fuchen.

In fact, there is no need for Dong Ren'an to wave, Gao Fei and Liang Fuchen will also come over.

Gao Fei took a look and found that there was a stone slab under the silt, with some vague lines engraved on it, like some very old text, Gao Fei stared at it for a while, and he didn't figure out what it meant, even the well-informed Gao Fei didn't know the words on the slate, and Liang Fuchen and Dong Ren'an couldn't even know it, and even Liang Fuchen and Dong Ren'an didn't necessarily know that the lines on the slate were a kind of text, they probably thought it was a decorative pattern, right?

Of course, it is impossible for a stone slab engraved with ancient characters to appear on the bottom of the sea for no reason, indicating that there is really an ancient tomb on the bottom of the sea, and as for whether it is an imperial tomb, it needs to be further verified.

If Gao Fei's cultivation was not sealed, he could use the perspective eye to check it now, but unfortunately, his cultivation was sealed, and the perspective eye could not be used, so he could only rely on his past experience to scrutinize and guess.

Seeing Gao Fei staring at the slate silently, Liang Fuchen was a little anxious, and kept gesturing with his two hands, wanting to open the slate.

It is easy to open the stone slab, but how to solve the problem of seawater inflow? Another problem worth noting is that after so many years of existence, the ancient tomb will definitely be corrupted, and the sealing will be greatly reduced, and it may have been flooded by seawater a long time ago.

If you really enter the sea water when you join the ancient tomb, then all the things buried in the ancient tomb will be damaged, and even the body of the tomb owner will be destroyed.

I don't know who is full of food, and I don't want to build ancient tombs in so many good places on the mainland, but I just ran to the bottom of the sea to build ancient tombs, was my head kicked by a donkey?

It is very difficult to build an ancient tomb on the bottom of the sea, one is a pressure problem, the other is a waterproof problem, if you are not careful, the ancient tomb will be destroyed, so as long as you are a person with a normal mind, you will not run to the bottom of the sea to build an ancient tomb, not to mention the ancient period, the ancient productivity was low, and it is even more difficult to build an ancient tomb on the bottom of the sea.

Just when Gao Fei was silent, Dong Ren'an took out a waterproof electronic product from his bag, linked his fingers, and typed a row of words on the screen: "What are you thinking? Why don't you agree to open the slate? Are you worried that after opening the slate, seawater will pour in and destroy the funeral goods inside?" Dong Ren'an was very smart and actually guessed Gao Fei's idea.

Goofy nodded.

Dong Ren'an continued to type, "I think the capable man who built the ancient tomb must have taken precautions to prevent seawater from entering the ancient tomb, so let's not think nonsense, hurry up and open the stone slab, I can't wait, I want to see what treasures are inside." ”

Liang Fuchen snatched the electronic product, linked his ten fingers, and typed a string of words, "I agree with Dong Ren'an's idea, since that capable man dares to build an ancient tomb at the bottom of the sea, he must be sure to prevent seawater from entering the ancient tomb." ”

Gao Fei thought about it carefully, and felt that what Liang Fuchen and Dong Ren'an said made sense, that capable person dared to build an ancient tomb on the bottom of the sea, he must have thought of a way to prevent seawater from pouring in, as for what method...... Goofy couldn't think of it for a while, maybe he would be able to open the slate and find out what was going on.

Liang Fuchen and Dong Ren'an took out a crowbar from their backpacks and went to pry the slate, found a gap along the edge, and then inserted the crowbar little by little......

One, two, three......

Oops, the slate was too heavy, far beyond Liang Fuchen and Dong Ren'an's expectations, and the two of them used all their strength and failed to pry the slate.

Gao Fei couldn't stand it anymore, stretched out his hand to push Liang Fuchen and Dong Ren'an away, and then pried the slate with his own hands, holding the crowbar with one hand and pressing it down, and then saw the slate move, although it was only a slight move, but it also made Liang Fuchen and Dong Ren'an happy, and the two of them gave a thumbs up and praised Gao Fei's strength.

Hey!

This stone slab is indeed not light, not to mention tens of thousands of pounds of weight, right? That is, it touched me, and if someone else came, there was really no way to take it, and the ancient tomb was built with tens of thousands of pounds of stone slabs, on the one hand, it could prevent tomb robbers, and on the other hand, it could strengthen the sealing of the ancient tomb, so that the sea water could not enter.

There are pros and cons to everything, it is not easy to transport such a heavy slate to the bottom of the sea, especially in ancient times when science and technology were not developed, it is even more difficult, but the ancients did it, and it was perfect, but I don't know how to do it?

"Click......"

The slate weighing tens of thousands of catties was pried up little by little by Gao Fei, "poof...... "When the slate was lifted, the sea water poured into it at once, and Goofy couldn't stop it.......

Alas...... Gao Fei sighed secretly in his heart, what I was most worried about still happened, the sea water poured in, the burial goods in the ancient tomb were destroyed, and this undersea expedition was in vain, no matter what, open the slate first, drag the slate with one hand, and with a slight force, the slate weighing tens of thousands of catties was thrown out.

"Boom !!"

The slate fell dozens of meters away, and the huge impact caused the sea water to churn violently, and it took a while to calm down.

After the stone slab was lifted, a black hole was revealed below, and Gao Feiyi was bold, and he was not afraid of traps below, so he jumped down without hesitation.

Dong Ren'an was the second to jump, and Liang Fuchen was the third.

Seeing the seawater pouring into the ancient tomb, Dong Ren'an and Liang Fuchen were in a hurry, hurry up, hurry in, and see if they can grab a few burial goods before the sea completely floods the ancient tomb......

When the three of them entered the ancient tomb, they were directly stunned by the scene in front of them.
