Qin Beiyang didn't say a word, and struggled to open the manhole cover. The light pierced him so much that he couldn't open his eyes, and he was the first to burrow under the lid.

He didn't fall, and he didn't have steps or handrails, just crouched on the ground, starry sky overhead. Incredibly, he staggered to his feet, the white desert, and the biting wind was blowing at night.

This is not hell, this is under the earthly sky.

There was a round well at his feet, and another hand came out, and it turned out to be Inka. He dragged the Loulan girl up, then Katya, Sven Heding, Li Longsheng, Xiaojunwang, Professor Wang Jiawei, and finally the town's tomb beast Nine Colors.

It is unbelievable that heaven and earth have turned upside down.

The manhole cover that seems to lead to the ground is actually the ground of Lop Nur. Or is gravity reversed? The dungeon does not go deep underground, but is like a reflection next to the bottom of the basin of Lop Nur Lake, hanging upside down in the underground world, like a bat. As long as you break your foot, you can return to the ground. If you go up, you go deeper and deeper into hell.

"The mirage, an ancient divine beast, can not only spit out mirage-like illusions, but also create more natural wonders."

"Beiyang, do you remember our adventures in the Arctic ice island, in the Viking tomb?"

"You say that's a mirage too?"

Li Longsheng looked up at the dawn of Lop Nur: "Perhaps, there is a large amount of toxic sulfur gas in the crater, which affects the central nervous system of people, and then produces illusions, similar to the effect of smoking marijuana and other psychedelic drugs. Last year, I visited the great psychologist Carl Jung in Switzerland, and he was very interested in our adventures, but the Viking Valhalla, Ragnarok, Fenrir the wolf, etc., are not very credible and still belong to the category of mythology – even an extremely important dream, implying major discoveries in human history and philosophy, and part of the collective unconscious.

"The collective unconscious?"

Jung believed that the collective unconscious can be traced back to our ancestors, such as primitive man's fear of beasts, darkness, and death. Our adventures in the Arctic awaken the heredity of fear in the depths of memory, which is related to the ancient times of half-humans and half-gods, and the origin of primitive religions, and is an extremely complex psychological phenomenon that cannot be simply classified as a hallucination......"

"In the mausoleum of the Vikings, we went crazy together?" Qin Beiyang had a splitting headache, looking at the wellhead in the desert that had been added for no reason, and then he remembered the ghost, "What should I do with my sweat and blood?" ”

"Let's dig the wellhead."

Xiaojun Wang and Professor Wang both carried archaeological iron pickaxes and smashed dozens of times in sweat. Under the basin of Lop Nur Lake is loose and cracked salt marsh soil, and a three-foot square hole is quickly made.

The ghost god was rescued, and the horse was suffocated, spreading its hooves and screaming at the sky.

However, Xiao Mu disappeared completely, and no one saw him crawl out of the well.

Qin Beiyang knew that Xiao Mu would not die easily.

On the horizon, a fiery red sun rose, so beautiful that people instantly petrified. The heat rose, the black smoke disappeared, and the phantom of Loulan City two thousand years ago finally disappeared.

The wellhead at the foot of Qin Beiyang suddenly closed automatically and turned into a compacted salt marsh lake basin again. Perhaps, all the apparitions, including the mirage, come from here, and this is the breathing hole of the mirage.

"How do we get out?"

The little king reminded that there were no camels, only a horse and a "hound". And the water bladders on their waists were all used by Sven Hedin to water the mirages in the dungeon.

Everyone looked at each other, and Inka shook her head: "I don't know how to go home." ”

"Then let's go towards the sun."

Qin Beiyang smiled slightly, this is the son of the craftsman, a young man born in the underground palace, a man who walked all the way to the black.

Ladies come first, and he leaves his sweat and blood to two women: Katya and Inka - they don't speak the same language, but they are like-minded.

The men walked in the back. By the saddle of the ghostly god, there are several water bladders and two large pieces of cut cake marline, which finally come in handy in times of crisis. Fortunately, in the cold winter season, it is cool except for noon, and it will not evaporate and lose water in the sun.

After walking for a day and night, there stood a small earthy yellow hill in front of me. It is not a natural Yadan landform, there are traces of rammed earth, and there are artificially dug caves inside. Qin Beiyang climbed to the top of the height, dug up a layer of loess, and found many traces of burning. Xiao Junwang grabbed a handful and put it in front of his nose, feeling a foul smell.

"Wolf dung!" He is a Mongolian, and he is no stranger to this, "Once the wolf dung is burned, it will form a sky-high black smoke, which the ancients used to transmit information, hence the name wolf smoke." ”

"Isn't it a beacon tower in ancient times?"

Qin Beiyang set up a pergola with his hands, and saw the remnants of the mound stretching from east to west, as if a straight line had risen from the flat ground, and there was no end in sight at both ends.

"The Great Wall of Han." Professor Wang Jiawei also climbed up, "Zhang Qian passed through the Western Regions, and Li Guangli, the general of the Second Division, invaded the Dawan Kingdom, and the "Hanshu Western Regions Biography" recorded that 'from Dunhuang to Yanze in the west, there are often pavilions, and there are hundreds of field soldiers in the wheel platform and canal plows...... Yanze is Lop Nur." The Xiongnu conquered the Han Dynasty one by one, and the Western Regions set up a protectorate, and the Han Dynasty established the Fengsui and the Great Wall in the entire Western Regions. ”

The professor also pointed to the small earthen bags under the beacon tower, which seemed to have many fibrous materials: "Lop Nur Daze is rich in reeds, and the Han Dynasty people piled them up as fuel, called 'Ji Salary'. ”

The Great Wall is not only to Jiayuguan and Yumen Pass. Two thousand years ago, the Great Wall stretched along the Silk Road all the way to the west, like a giant dragon......

Qin Beiyang closed his eyes and imagined that the soldiers of the Western Han Dynasty and the Eastern Han Dynasty were far away from their hometowns, and the people of the Long March had not returned, guarding the beacon towers along the Great Wall.

China's wolf smoke.

That night, they slept in the ruins of the beacon tower of the Han Dynasty, who knew that two thousand years ago, Ban Chao, who threw a pen from Rong, did not spend the night here?

Qin Beiyang recovered his spirits and wiped the Tang knife and crossbow, any weapon needs to be well maintained, otherwise it will become scrap copper and rotten iron.

Sven Hedin saw the markings on the crossbow and asked, "The one-eyed pyramid?" ”

The Swedish explorer really knew the goods, and Qin Beiyang replied in German: "Sir, do you know this mark?" ”

"Artisan Union."

Hearing this phrase, Li Longsheng also came over and said: "For this expedition, the Artisan Alliance gave secret funding. ”

Sven Hedin said in German: "When I was young, I wanted to join the Union of Craftsmen, because explorers like us are born with a love for all kinds of mystical things. But I don't have an ancestral craft, and I'm already in college, so I'm being shut out by the Artisan Union. ”

The arrogant Swedish explorer, a conservative, discouraged democratic elections and opposed the parliamentary system. During the World War, Sven Hedin openly supported the German Emperor, and the outcome of the Great War put him in an embarrassing position. This expedition over the Himalayas was a great opportunity for him to regain his reputation.

"Why would they fund the Silk Road expedition?"
