This made Yuan An puzzled, since his debut, it was the first time he had encountered such a strange ancient tomb.

Although the layout of this ancient tomb puzzled him, this discovery made Yuan An very excited, and such an unreasonable ancient tomb strengthened his idea of wanting to find out.

But it was still early at this time, and it would be easy to be discovered if he did it now, so he decided to come back in the evening and prepare something to be applied by the way.

That night, Yuan An took his things and came to the mountain beam again. Even though it was night, he didn't dare to light the lamp, and a lamp was lit in the middle of the night, which was too eye-catching, but fortunately, the moonlight was still bright that day. With the help of the moonlight, after Yuan An determined the location of the thief hole, he danced the steel shovel in his hand, and an inclined thief hole was quickly hit.

Yuan An's location of the robbery hole was very accurate, until it reached the intersection of the tomb wall and the tomb roof. The reason why this position was hit is because the top of the tomb is the hardest part of the entire tomb building, and of course, it is also the part that is least likely to have a mechanism. If you want to go down from the top of the tomb, you can only use explosives, which is called a large cover in the jargon.

The tomb wall is the easiest place to place traps. For example, quicksand, gravel, strong acid, mercury, etc., may be arranged in the mezzanine of the tomb wall, and Yuan An's robbery hole hits the top of the tomb wall, even if there are these things, the amount will not be very large, and it can be dealt with.

Yuan An touched the tomb wall, and probably understood the structure and age of this tomb. This is an ancient tomb of the Qin and Han dynasties, and it adopts a relatively common structure at that time, that is, the vertical pit soil pit is supplemented by a hollow brick tomb wall, and the top of the tomb is a stone beam with white plaster. Yuan An gently picked up a green brick, put it in his hand and lit it, and then shook it carefully to make sure that there was no strong acid oil or mercury in the brick.

Then slowly knock off some hollow green bricks to widen the hole. Yuan An turned on the flashlight and shone it on the façade of the tomb wall, and it was pitch black inside. Yuan An knew that this kind of vertical pit and soil pit, and like this small-scale, the structure is relatively simple, with a maximum of two rooms, or even very likely only one room, in this case, the coffin should be directly below the cave entrance, and I am afraid that there will not be too many burial goods. But at this time, Yuan An was not concerned about how much money he could make on this trip, but wanted to figure out the reason for the strange layout of this ancient tomb.

Afraid of the foul air in the tomb, Yuan An held his breath and looked down cautiously. This look, Yuan Anxin is cool, because the construction of this ancient tomb is not so precise, the structure is also simple, and now the bottom of the tomb has entered the water, and the stagnant water is mixed with mud, making the tomb full of mud, and it looks very deep.

Yuan An retreated, a little disappointed in his heart, it seemed that this time he was really going to return in vain. As much as he wanted to find out the secrets of the tomb, he couldn't risk jumping into a mud pit of unknown depths.

Yuan An, who did not give up, shone a flashlight on the tomb walls on all sides, hoping to gain something, but unfortunately there was still nothing. Yuan An sighed in disappointment, and just as he lowered his head, he suddenly saw something that seemed to be floating in the middle of the mud.

Yuan An hurriedly shone it carefully with a flashlight, and found that what was floating on the mud was a black wooden box. Yuan An was very surprised when he saw it, a wooden box had been soaked in mud for so many years, and it had not decayed, so it could be seen that this must be a treasure.

"It's worth the trip to pick up this box." Yuan An said secretly, visually measured the distance from his hole to the mud, and then hooked the edge with his foot, made an upside-down golden hook, hung his body down, and reached for the wooden box floating on the mud.

This Yuan An is also a master of art and bold, the entrance of the cave is full of mud, if he falls head-down, he will definitely die. However, Yuan An was also lucky enough, he hung down and stretched his arms straight, which would be just enough to reach the wooden box.

Yuan Anxin was happy, held the wooden box with both hands, and lifted it upwards hard, seeing that a wooden box about thirty centimeters long and twenty centimeters wide was lifted.

Yuan An was trembling all over, his feet were loose, and he almost fell. But now it is absolutely unacceptable to let him go and give up the wooden box, with his character. Yuan An gritted his teeth, launched a ruthless attack, held the wooden box with one hand, and then pulled out a dagger from his waist with the other hand, this dagger was extremely sharp, and it was also obtained by accident when Yuan An was fighting.

Yuan An clenched the dagger and swiped hard at that hand, and suddenly the thumb of that hand was cut off, so that the hand could no longer grasp the wooden box, and slowly sank into the mud again. Yuan An breathed a sigh of relief, and with a slight force of his hands, he picked up the wooden box, and shook it with his hand, the situation inside sounded as if there was no water, which was good news for Yuan An.

At this moment, suddenly, the mud at the bottom of the entire tomb suddenly surged, as if something was about to come out below, Yuan An didn't dare to stay this time, he returned to the cave with a hard waist, and looked back, only to see the hand that had been cut off his thumb stretched out of the mud again. Yuan An hurriedly retreated from the thief cave with the wooden box, and then sealed the entrance of the cave.

Yuan An was frightened at this time, and hurriedly returned home with the wooden box.

Later, he managed to open the wooden box, and there was no water inside. After checking, he found that in addition to the waterproof and antiseptic treatment of the wood, the upper and lower parts of the entire wooden box were carved from a whole piece of wood, and the middle was artificially hollowed out and poured into molten white iron. This process is simply breathtaking, the high-temperature molten iron did not burn the wood, I don't know how people did it at that time, and it is precisely in this way that the sealing of the wooden box is excellent, and it also ensures the integrity of the contents inside the wooden box.

Inside this wooden box is a roll of gold silk brocade, on which is the self-report of the owner of the tomb. In the 37th year of the reign of Qin Shi Huang, he and 500 crossbowmen were ordered to go to sea with Xu Fu, a fellow of hundreds of boys and women, and some craftsmen. It is intended to find the fairy mountain on the sea. They have gone through twists and turns, but they have come back in vain. During this period, he encountered hardships and dangers, and also shot and killed a huge sea fish.

Although they returned empty-handed this time, Qin Shi Huang Yingzheng felt that such a huge fish was absolutely extraordinary, and this was a revelation from heaven, so they went to sea again.

And this time, they finally got something, and on a foggy day, they found a huge island. After arriving on the island, they were surprised to find that there was an altar on the island.

Xu Fu and other scholars who accompanied the ship were extremely surprised by this discovery. They unanimously agreed that this was a miracle, that this was the fairy mountain on the sea, so they ordered that only the boys, women, and craftsmen should be left behind, and everyone else should board the ship ten miles away from the island, and not approach it at will, so as not to anger the immortals!

The lieutenant and the others could only get on the boat and leave, away from the island. For a long time, they were confined to the ship, not knowing what was going on on that island.

It was because they were far away from the island that they discovered a strange phenomenon, that is, the clear weather, but they could not find any trace of the island at all, only in the foggy days, the huge outline of the island can be faintly seen. This discovery not only did not make the captain feel how magical this so-called fairy island was, but it made him feel that this island was extremely eerie and weird, and he was a little frightened in his heart.

Finally one night a fog rose again on the sea, and the fog was thick, just as it had been when they first discovered the island. The captain and the others were just about to rest, when they suddenly heard a loud noise from the direction of the island, and they hurriedly ran to the deck to take a look, only to see a huge black shadow rising up above the outline of the island. Then it disappeared again in the blink of an eye.

Everyone was stunned by the scene in front of them, many of them stood on the deck, and some even began to bow down in the direction of the island. At that moment, someone noticed something floating on the sea, and when everyone shone it with torches, it turned out to be the corpses of those boys and girls.

A bold man pulled up a corpse with a net, but found that the corpse was covered in blue and black, and he was about to reach out and touch it. But he was hurriedly stopped by a well-informed veteran, who told the others that the body had been doused with mercury and died. Don't touch it, be careful of poisoning.

After listening to the old soldier's words, everyone wondered why these boys and girls were poisoned with mercury.

The veteran said there was only one reason for this, and that was as a burial. Because after being poured with mercury, the body does not decay, and there will be a faint smile on the face, since ancient times, the burial of boys and women have used this method of filling with mercury.

Hearing these words, the hearts of the people were chilled. The veteran said that in this way, the island should be repaired.
