"The principle of this is similar to that of shadow puppetry! But we were just around the campfire and saw nothing on the wall at the doorway. Could it be that this painting is engraved in the black ball on the hand of the stone figurine? Liu Xilai asked curiously.

"Probably not, if that's the case, no matter how you take it, it's only this one picture, and it is impossible to have different content. But according to the standard ten earthly branches on this platform, there should be ten paintings. Luo Gang scrutinized.

At this time, the soldiers who were resting by the bonfire at the door were surprised to see the mural that suddenly appeared on the wall, thinking that something was wrong, so they quickly got up and stood on guard, and heard Luo Gang's voice coming from the platform in the center of the dome: "Don't panic, everyone, this is just a projection, come over two people to help me, and the rest continue to rest." After the two comrades-in-arms walked up to the stone platform, Luo Gang instructed again: "Abramaimaiti, you come with me and help me." Liu Xilai, you are responsible for taking turns with the other two comrades-in-arms to turn on the lights, projecting the murals in the order of the ten earth branches, listening to my signals, and then changing to the next angle projection. Remember not to touch the stone figurines and the black ball in his hand, there are traps on it. ”

After explaining the matter, Luo Gang walked to the left side of the door, took out the camera from his back, took a picture of the mural, and then took out a notebook and a pencil and handed it to Abramaimaiti, saying: "You kid usually loves to draw and sketch so much, today you will be given a chance to display your talents and show your revolutionary energy." If you draw well and carefully, you may be able to bring some valuable information to the national scientific archaeological research after you go back. ”

Abramaimaiti took the pen and paper and quickly sketched out the contents of the first mural.

The first depicts a bird god and a figure in a green sand robe, kneeling in a palace, and at the other end of the ornate staircase there is a platform, on which the gorgeously dressed king with a golden crown smiling, and in the center of the hall there are four soldiers, one holding a sheepskin map to be unfolded for the emperor, and the other pair carrying a huge tray with many black spheres in the tray. The first mural is actually about a Taoist priest who is offering a treasure to the king.

Luo Gang shouted at Liu Xilai, "Next, B!" ”。

I saw that the first mural disappeared, and another mural appeared next to the first. The second mural depicts a Taoist priest directing a number of craftsmen to build a large domed castle, and in the center of the castle is a black bottomless cave, with a spiraling staircase sticking to the cave wall and extending downward. It didn't seem to be anything unusual, and while Luo Gang finished taking the photo, Abramaimaiti also finished sketching quickly. "Next, Liu Xilai!" Luo Gang shouted.

The third, the C mural. The dome castle has been built, the Taoist priest stood next to the cave in the castle, raised a black sphere above his head with both hands, and a beam of strong light shot from the dome just shone on the black ball, and then through the black ball turned into green light, straight into the bottomless cave. The cave seemed to have many distorted and strange faces, and the stairs were full of all kinds of strange animals, some like elephants with a duck's beak; Some were human-like, but covered with scales and hairless; The most bizarre thing is that there are a lot of things that look like smoke and people, fluttering on the stairs, as if they are about to come out of the hole and down the stairs.

Seeing this, Abramaimaiti couldn't help but shiver, and asked Luo Gang slightly: "Is this the void?" This King of Loulan actually opened the gates of hell and released all the evil ghosts to the world! It's horrible! ”。

"I can't tell you this, after all, we have only seen 3 murals, just like reading a story, and we have only listened to the beginning. Looking down, maybe there will be more detailed results later. Luo Gang comforted Abramaimaiti, with doubts and curiosity in his heart, he picked up the camera, adjusted the focus to shoot the whole scene, and took two close-ups of the location of the cave, and then called Liu Xilai to replace a mural.

The fourth mural is even more strange, the king who was originally very important to the Taoist priest actually ordered the soldiers to tie up the Taoist priest and take it away, and then ordered hundreds of soldiers to transport a piece of a piece about 3 in diameter and half a person in height, to seal the bottomless black cave. Luo Gang took a photo, Abramaimaiti sketched, and Liu Xilai took the next picture, and the two groups quickly adapted to this assembly-line operation mode.

The fifth mural is even more bizarre, as the scene of the first four murals has changed, and the location and protagonist of the previous four murals have changed.

The mural depicts a river confluence on the Gobi Desert desert, with only the king holding a black orb in his hand, shining brightly, with no soldiers or guards of honor behind him. The wind blew fiercely over the waters, lightning flashed and thundered, and dragons that reached the sky to absorb water appeared. At this time, the sky is covered with dark clouds, a strong light shoots out from the dark clouds, a huge mountain in the shape of a triangular pyramid is suspended in the air, the top of the mountain is facing down, the foot of the mountain is on the top, there are many palaces on the mountain, the crowd between the palaces is dense, coming and going.

"Could this be the legendary Nine Heavens? The world up there is also quite busy! Liu Xilai also watched this scene and said with emotion!

"Could this be a mirage? What about the mountain suspended in the clouds and standing upside down? There is no mountain in the world that is upside down, and it is impossible to build so many houses and live on it! It's really evil! Luo Gang couldn't help but sigh.

"Squad leader, his grandmother is a horse manure, it's so complicated, I can't do it! What to do! Abramaimaiti asked anxiously.

"Just draw a rough idea, I've taken a lot of photos, and I've taken a close-up of the part of the Cloud City." Luo Gang replied.

"Next!" With Luo Gang's instructions, Liu Xilai changed the angle again, and the sixth mural slowly appeared on the curved wall.

In the seventh mural, the boulder in the center of the dome castle is chiseled open, and the king of Loulan holds a lamp and a black ball, leading the soldiers slowly into the cave. At this moment, the dome was kneeling together with men and women, old men and children, who looked reverently at the black hole in the center of the dome, crossed their hands on their chests, and seemed to be praying for something.

The eighth is even stranger. The king of Loulan led his soldiers to stand on a large mountain and look into the distance, and above their heads it was not the sky, but the same mountain as under their feet. It's just that it's upside down, and there are people walking upside down on the mountain, and the mountains on the ground in the distance are connected with the mountains in the sky.

"This is really beyond all of us, is there another world underneath?" Luo Gang was completely tempted in his heart. At this time, he didn't think about it so much, pointed to the last two murals at once, quickly left here, returned to the Milan farm, and handed over this incredible news, as well as the photos taken, to the state.

"Next! Fast! Luo Gang shouted hurriedly. Liu Xilai immediately cooperated, aiming the light of the flashlight at the direction of "Ren".

The ninth mural completely calmed Luo Gang and Abramaimaiti. In the mural, the king of Loulan and his soldiers confront each other with a group of strange people dressed in gorgeous tinsel clothes, with fair skin and blue skin, and their eyes are extremely black, with no noses and sharp teeth. Among them, the stranger closest to King Loulan handed a round ball the size of a silver billiard ball to King Loulan. King Loulan looked happy and seemed very satisfied.

"His grandmother is a horse manure egg, this Loulan Wang's experience is really amazing! Quick, Liu Xilai for the next one! Luo Gang stared at the mural and said without looking back.

"Squad leader! The next one is gone! Liu Xi said.

"What? Aren't there ten earthly branches? How can there be one worse! You're looking to see if the angle of the flashlight is wrong! Luo Gang said anxiously.

After two minutes, Liu Xilai said again, "Squad leader, it's really gone, I tried it from all angles, this green light hit the wall, and nothing appeared on the wall!" ”

Luo Gang didn't answer him, and walked straight to the wall with green light and looked at it carefully. After a minute, he walked to the right of the wall five or six meters, looked at the wall next to him, and was silent for a long time. Liu Xilai and Abramaimaiti, as well as other comrades-in-arms, all stared at him nervously when they saw that Luo Gang did not speak.

"Hahaha, I see! I know! The ancients are truly amazing! Luo Gang's sudden laughter and self-talk scared everyone into a thrill.

"Abramaimaiti, what is the difference between this wall and the one on the left?" Luo Gang dragged Maimaiti to the wall and asked.

"It makes no difference!" Abramaimaiti glanced at the walls on either side and replied.

"You kid take out the eyes you look at the big girl, and take a closer look!" Luo Gang said anxiously.

At this time, everyone looked at Abramaimaiti and Luo Gang, not knowing what medicine was sold in Luo Gang's gourd, while Abramaimaiti stared at the wall, staring wide-eyed to see the difference between the two walls.

"In the direction, the wall corresponding to the ninth mural is uneven, as if some glittering fine sand was smeared when the wall was plastered. And the Aoi position, which corresponds to the tenth mural, is smooth and flat, and there is no sparkling fine sand. There is indeed a difference! Abramaimaiti said, holding his cheeks.

"Definitely! That's why the first nine murals all appeared, while the tenth did not. Luo Gang explained. Without waiting for Abramaimaiti to think, Luo Gang said: "This is a paint that will show color when it encounters a specific color of light, and I used it in my early years when I was a camel handle, and I saw some painters in Kyakhta repairing temple murals. This pigment is actually made by quenching the sap of a certain tree or plant, and when used, this sap is mixed with rosin and heated, and the mixture is applied to the corresponding place where the mural is needed. Rosin is the pine resin oozing from the pine tree, which is transparent in itself, and after painting on the wall, it is brushed with a layer of white, and there is no trace of painting at all. ”

Abramaimati interrupted Luo Gang and asked eagerly, "Then why is it that the walls of the first nine murals are uneven, but the walls of the tenth murals are uneven?" ”

"What's this? There are three possibilities: first, the last mural disappeared for some reason, or was destroyed and polished; Second, the domed castle temple was not completed, and the tenth fresco was not completed; Thirdly, this kind of temple has been completed, but there is no tenth fresco at all. Luo Gang held his cheeks, deduced, and then said, "The stone platform and stone figurines in the center of this ancient castle, as well as the black ball and the black ball hanging wire mechanism held by the stone figurines' hands, the machine is neat, it seems that it should have been completed, it shouldn't be!" ”

"The walls of the first nine murals correspond to the orientation, probably because of the climate of Lop Nur, the position of the wall without paint caused by the large wind and sand and large temperature difference is weathered, and the position of the paint is relatively slow to weather, so the uneven wall surface is produced. As for the orientation of the tenth fresco, the walls themselves are smooth and have no clear boundary with the walls on both sides, so it should be considered that they have not been treated. Luo Guang looked at Abramaimaiti,

"There really aren't any clear dividing boundaries or man-made marks on the walls. Monitor! You are God! This can all be deduced! Abramaimati looked at Luo Guang with admiration.

"In that case, this tenth mural doesn't have it at all! Perhaps this last mural is the secret of the disappearance of King Loulan and his people, but this is a secret that no one will ever know. Luo Gang sighed.

"Squad leader, the sandstorm outside has stopped!" A little warrior shouted by the campfire, interrupting Luo Gang's thoughts. Luo Gang sorted out his clothes, turned around and motioned to Liu Xilai and the two little soldiers, and returned to the campfire. By the time Luo Gang walked to the campfire, Abramaimaiti had already handed out the notebook and pencil to return to Luo Gang. Luo Gang didn't say anything, put away the book and put it in his shoulder bag, and said to everyone: "The sandstorm has also stopped, we have delayed for about 4 hours, we can't delay it any longer!" Everyone packed their bags and supplies, and we set off immediately. Whoever is the first to go back and tie the camel first can eat 2 more nests today! ”

With that, Luo Gang climbed on the camel and walked out of the castle leisurely. I only heard Liu Xilai shouting behind him: "Wait for me!" I'm the youngest on our team, I'm growing my body, and I need my head the most! ”……

In the distance, in the rolling sand dunes, another camel caravan appeared......
