The night was dark, and the wolf did not whine.

Siye was silent, and his heart was very frightened.

I didn't sleep well last night.

In the morning, Hua Bo didn't want to go with everyone, he just wanted to stay alone in Beihua and die with Beihua.

Repeated persuasion was useless, Xia Fan only left some food.

Xia Fan watched Hua Bo lie down in the coffin again, and when he turned around, tears were already rolling in his eyes.

Suddenly, Hua Bo struggled to lean out, last night he knew that Xia Fan and his party were going to the high mountains over there to eliminate the evil dragon, and Hua Bo was very supportive.

Hua Bo asked Xia Fan to come close and untie a straw rope necklace on his chest.

The chain was hung with a black pendant, and Hua Bo said that this amulet could bless everyone, so that Xia Fan must wear it.

Xia Fan held the necklace in his hand and started very heavy.

The pendant is an ancient black stone that has been carefully polished into an oval shape.

Hua Bo took out the white mongoose from his arms again and handed the white mongoose to Xia Fan:

"Take it with you, Xiaobai is the last living creature of this tribe, it is very smart and spiritual, I hope it can help you."

Xia Fan stroked the white mongoose and couldn't bear to say: "Uncle Hua, it's okay if you don't let it accompany you, I took it away, who brought you food?" ”

"I don't have much time left, and when he passes by here again as he lives, he puts my dry bones into the top of the dirt holes at the entrance of the village, and there is a wooden sign with my name written on it."

Xia Fan finally couldn't help it, and tears welled up in his eyes. I didn't let everyone in at the beginning, and Xiaoyu would definitely cry when she came in.

Xia Fan held the ferret in his arms, its small fangs bit Xia Fan lightly, and then threw himself into Hua Bo's arms.

After repeating this many times, the ferret finally stopped resisting.

Hua Bo asked Xia Fan to cover the animal skin on the coffin and told Xia Fan to hurry on the road. Everyone was waiting for Xia Fan. That's on the road.

None of the things encountered in the past two days made everyone happy, and after listening to Warber's story last night, everyone was even more depressed, thinking that the closer they got to this mountain of evil dragons, the more strange and hellish warnings there were. Fortunately, the pig fell asleep and didn't know anything, otherwise he might have retreated. People don't want to talk about last night, and ignorance and ignorance can sometimes be a blessing.

Coming out of the Beihua tribe, I returned the same way, and it took a while to walk this settlement like a peach source. After that section of the dirt slope, there was indeed a hole at the top, higher than all of them.

Xiaoyu didn't sleep well last night, she fell asleep on the elk, she is not like this usually.

Xia Fan and his party continued to move in the direction of the Evil Dragon Mountain.

Turning over a grassy slope, the white mongoose bit Xia Fan's hand, Xia Fan was in pain, let go of it, and it immediately jumped into a stone on the side of the road, then stood up, looked at everyone with two eyes, and looked into the distance, and then quickly ran to the grass next to it, and disappeared in a flash.

Xia Fan's heart tightened, it wouldn't run away.

One moment a little head burrows out of the dead grass, and it comes back, and then it burrows into the grass again, and then it pokes its head out again.

There's something in the grass.

Xia Fan got down from the pig's back and motioned for everyone to wait.

Dig into the grass, look for it, but it's good that it's prominent, it's showing the way?

Seeing that Xia Fan didn't keep up, this little thing turned around and came to Xia Fan again, back and forth several times.

Xia Fan slowly understood what it meant, and asked everyone to keep up with it.

In a place shaded by deep dead grass, there is a path that leads to the opposite hill.

Xia Fan said loudly, let everyone wait, and strive to catch up with the ferret who ran up the hill.

The wolf followed Xia Fan, and only the wolf could completely keep up with the speed of the ferret.

There is a flat land on top of the hill, and there are a lot of trees inserted horizontally and vertically on the shallow grass, like a tombstone. There was only one tombstone that was a standing stone of a strange tamares, and the ferret stopped next to the tombstone and stopped walking.

The soil next to this tombstone is very different from the surrounding one, and the surrounding grass just circles its place.

Xia Fan Guanzhi, the location of this cemetery is very well chosen, surrounded by a circle of trees, the whole cemetery sits north and faces south, judging from the wood and this standing stone, if one person and one pit, there are more than 30 people buried here, forming the shape of an arrow sitting north and facing south, and this standing stone tombstone is just the top of the arrow.

This is a cemetery of ancient people? There's something under this tombstone.

There must be something in the grave under this tombstone, something that this clever ferret and Waber wanted to leave us.

Xia Fan asked the wolf to find the tiger, leopard, bear, pig, Xiao Hei and the one-eyed dragon. After a while, everyone also arrived at the standing stone tombstone, and the pig, thinking that he was fat, rushed up the grassy slope with great difficulty, panting.

Xia Fan explained his intention, that is, to dig this grave. Everyone looked embarrassed and refused.

Thinking about it, the ancient people worshiped ghosts and feared gods, they didn't know why their kind would die slowly, the fear of death was like a mysterious thing beyond thought, they would mummify the dead, they would see death as life and pray for an afterlife, and even a tribe in Africa would eat the dead kind, as if the same kind would be with them forever, so as to seek mysterious power. In fact, they don't know the seriousness of the consequences, such as contracting prions that are not clear in modern medicine.

Xia Fan explained all kinds of explanations beside this tomb, and guided everyone for a while, and then everyone agreed to dig this grave under the standing stone.

Dig out the shallow grass and soft soil on the top, and the rammed earth is obviously compacted underneath, and after a while, the rammed earth layer is dug up, and a black clay appears.

A deep pit slowly emerged.

The pig's wooden nail rake no longer worked, and after a long time, a lot of ways were dug out. The tiger used his tomahawk to drape open a dead tree next to it and make two shovels. Several people took turns to dig this black soil, and this black clay was fine and compact, which was really not easy.

Just dig little by little, expand to both sides little by little.

"Got it!" Brother Leopard shouted, and it was obvious that the planer was against the hard object. The wolf was at the mouth of the pit, spinning in circles restlessly. The ferret jumped on the wall of the pit and back onto the pit, and was not restless.

The black soil is gradually dug up, and this sarcophagus has its true appearance, this sarcophagus is an irregular oval shape, and it is quite well done. It is full of patterns, and this pattern looks like I have seen it somewhere. The craftsmanship of this ancient man is so exquisite, I can't believe it.

Xia Fan jumped into the pit and groped to find an edge of the sarcophagus, which was strange, like there were no edges and no gaps.

Planing off the black soil on the sarcophagus, this pattern is actually full of work, removing the various flowers and leaves in the corners, the pattern in the middle of the sarcophagus Xia Fan saw clearly, it turned out to be a variety of formulas, full of formulas, no repetition, a formula written in a tadpole-like text.

In high school, Xia Fan's physics and mathematics were the best, as long as the science exam was difficult, Xia Fan could enter the first examination room of the grade, of course, Chinese is also good, after all, love to read, the worst is English, a girl in the class with a similar rank to Xia Fan is more than one hundred and forty years old, Xia Fan is often more than one hundred and a half, and the English level is also at the middle and lower level in the class, all relying on science points.

There are many formulas on this sarcophagus that I can't understand, but these four are vaguely visible:

△v=|v1-v2|/√(1-v1v2/c^2)

L=Lo*√(1-v^2/c^2)

M=Mo/√(1-v^2/c^2)

t=to*√(1-v^2/c^2)

This is the formula of relativity, which Xia Fan has seen in extracurricular books at university.

The man in this coffin is from the era in which he lives. ’

Before I came here, there were people who came to this time! Xia Fan's brain was numb.

This sarcophagus is indeed strange, to put it bluntly, the coffin itself is a rare thing in this era, not to mention that this sarcophagus is still so finely made, this is not a product of this era at all.

In the modern archaeological discoveries of ancient people, many ancient people's tombs did not have coffins, and some just dug a cave to bury them. But it's not rectangular, it should be like the boat shape of the Taoyuan tribe, Xia Fan remembered that the tomb of Princess Xiaohe is also a boat coffin, this boat-shaped coffin first processes two poplar trees into a pair of bracket-shaped wooden strips to become the coffin side panels, and the coffin lid is more than ten small baffles. A live cow is slaughtered on the spot, immediately skinned, and the whole coffin is wrapped in fresh cowhides, so that the bottom of the coffin is not needed, it is buried, and then buried with yellow sand.

And the Chinese heritage integration of thousands of years, many nationalities, many customs, Xia Fan once went to visit a group of hanging coffins of servants, all hung on the high cliffs, the coffins of servants are big and small, mostly cut and planed by the whole wood, fixed with the buckle and tenon, all of them are buried with straight limbs on their backs, and the body is wrapped in linen, and the burial goods are placed at the feet.

In this era of underdeveloped productivity, no one will use huge energy to make such a time-consuming and laborious coffin, even if it is productive, it cannot be achieved, so it seems that this sarcophagus is more and more incredible.

Everyone cleaned up the soil around this sarcophagus, and the sarcophagus was completely revealed. This sarcophagus is a very delicate stone carving, not to mention, it is still a rare irregular oval shape, and the eyes are full of ornamentation, which is very time-consuming and labor-intensive, and the key is to find the gap that opens up and down or left and right. This is not a sarcophagus that can be made by ancient craftsmanship.

Could it be that they also crossed over? But looking at this cemetery and this sarcophagus, it looks like it has been buried here for a long time. This white mongoose can find this place, it is really a spirit animal, and it has something to do with the people in this sarcophagus? So what is the relationship between Huabo and these people buried here? The ancestors of the Taoyuan tribe also crossed over? What time traveled through? Xia Fan was so confused for a while that he couldn't figure it out.

Xia Fan didn't stop in his hands, and kept groping for the way to open this sarcophagus. Found a small hole on the north side of the sarcophagus, it was oval, Xia Fan fumbled for a while, and remembered that the necklace pendant that Hua Bo gave him was also an oval, could it be the key, or try it, he took off the oval pendant, pressed it, and it was just fine.

The sarcophagus made a slight sound, and suddenly something like four handles stretched out from all around.

The tiger, leopard, bear and one-eyed dragon jumped down into the pit, one person with a stone handle, everyone one, two, three, and used their strength to lift up, and the stone coffin did not move at all.

The white mongoose is indeed human, jumping out of the pit and walking clockwise on this sarcophagus.

Is it telling everyone that the way this sarcophagus is opened is to rotate? Why don't you give it a try? Xia Fan said in his heart.

Xia Fan motioned for everyone to rotate clockwise, which was strange to say, it was an irregular ellipse, but it could actually rotate slowly.

After a turn, somewhere you can already see a black gap below.

"Turn again."

With each turn, when turning to a certain angle, the gap becomes larger, and when turning to the ninth circle, the sarcophagus is staggered up and down, and most of the bottom has been exposed, and it can no longer move, and the heavy lid is still not opened.

"What are you doing here, why don't you just take a hammer and smash it open." The words of the one-eyed dragon were also heard in the crazy stone, he picked up one of the double-headed hammers and smashed them at the sarcophagus, Xia Fan didn't have time to stop it, the indestructible bone hammer on the double-headed hammer was shattered, and the sarcophagus didn't even knock out a single crumb, which shows that the sarcophagus is hard.

"This stone is much harder than obsidian." Black said in amazement. Black knows that obsidian is not very hard. Xia Fan estimated that this stone coffin was harder than diamond, and it was made of materials that surpassed this era.

The one-eyed dragon smashed one with a double-headed hammer, and was heartbroken. The animal bones of this bone hammer are made of the hardest beast skull of this era, and it can be said that it is simply invincible in this ancient era, and I don't know how many ancient people's heads have been broken in previous battles, but I didn't expect to kick the steel plate here today.

"You can't force it." Xia Fan said.

In fact, Xia Fan and everyone have found a way, but they have not completely unlocked the way to open this sarcophagus.

'Can the white mongoose take us on to decryption?' Xia Fan looked around for the white mongoose, but it was gone.

In ancient China, there was a qualitative four-wheel text combination lock, which was opened in a circle. The ancient combination lock is mostly a horizontal cylinder shape, there are several runners of the same size arranged in the axis, the same number of words are engraved on the surface of the runner, and the two ends of the cylinder are two upright columns, and a lock beam is connected to the column, when the text on all the wheels turns to a certain position, the lock can be opened, and no key is required.

This sarcophagus could be the same principle, but it only has two turns. ’

No, you can't turn all the way to the end in a certain position. ’

Xia Fan put his ears close to the sarcophagus and asked everyone to turn slowly, and when it came to the sixth turn, Xia Fan did hear an obvious click, and then the sarcophagus sank down, as if sliding to another slide, it seems that this idea is right, then continue.

Xia Fan commanded everyone to go back and forth left and right many times, and it took a lot of effort. It took about two hours to finally open the sarcophagus.

The arduous size of opening the sarcophagus was difficult to describe, but the moment it was opened, everyone was stunned.
