After all, He Chao was still calm after being a secretary behind Fang Sheng for so long; Yu Xiaoting didn't fully understand; Su Ruotong jumped up in shock and shouted:

"You mean...is the ancient castle with Karbor hidden under the ground?!"

Fang Sheng replied slowly, "At first glance, I always felt that I had seen the patterns on the small stone pillars. When I contacted the ancient Shu Kingdom, I finally remembered it. It was the strange smiling face of the bronze mask unearthed from Sanxingdui! There are actually many puzzles about the bronze ware in the ancient Shu Kingdom, and there is no technological inheritance at all. The longer it is, the more exquisite it is, the more amazing it is. For example, the Tongtian divine tree, the sun bird, etc., it is simply amazing and incredible. However, the bronze ware cast during the bow and fish country period is so rough that it is unremarkable, and it is like the national strength of the ancient Shu Kingdom, which is very strange. The outer formation is related to the Sanxingdui civilization. What does it mean when I found a copper lamp with the image of a Yufu in the wooden house? "

Yu Xiaoting finally understood: "Oh, is the entrance to the castle?"

"No possibility cannot be ruled out." Fang Sheng said implicitly.

"Look quickly and look quickly. If we find the castle, we will be very excited!" Su Ruotong was eager to do anything, then realized something, glanced at Fang Sheng and added seriously, "The excavated cultural relics belong to the country."

Fang Sheng laughed and said, "How can you find it so easy? It's too early to discuss ownership issues."

Yu Xiaoting had a slight understanding in her heart, and she vaguely guessed that Fang Sheng always liked to bring Su Ruotong with her: his identity, status and pressure he faced really needed such a likable pistachio, which had nothing to do with eroticism!

The women before him, either reserved, cold, dignified, or wise, lacked Su Ruotong's lively and cute side. They were a little close to Ye Yun, but unfortunately they were lying quietly in the hospital.

"It is very easy to dig modern technology. Just adjust the mining machine and hit the drilling rig down, and take down all the mechanism traps." He Chao said with a smile.

Fang Sheng also laughed, staring at the pattern holding the golden stick in his hand and was stunning, saying, "The golden stick represents the power of the monarchy and monarchy. It seems to be the habit of the Sumerian civilization in the Mesopotamian Basin. Chinese civilization has never existed before, but it is difficult to defeat a group of archaeologists. How can we justify the ancient Shu Kingdom into Greater China..."

Everyone laughed loudly. Fang Sheng used his hands unconsciously. Suddenly, with a "square-bar" sound, the copper lamp was twisted half a circle, and the copper platform chassis suddenly "cranked" and three copper strips as thick as fingers popped up!

"Hey, what's the use for this?"

Yu Xiaoting stood the copper lamp on the table, but the lengths of the copper strips were obviously not the bottom.

"Xiao Ting, how did you take it out just now?" Fang Sheng asked.

"Hold it flat like you just now, including the copper platform chassis..." Yu Xiaoting gestured.

Fang Sheng thought for a while and said, "Don't you think this look looks like a key?"

"Yes!" Su Ruotong shouted, "The wooden wall on the north side is close to the cliff, and it is likely to be connected to a switch somewhere!"

Yu Xiaoting hesitated a little, "Do you still plan after the rescuers come? I always feel..."

"Try it!"

He Chao and Su Ruotong said in unison, "After young, I can't suppress my strong curiosity."

Yu Xiaoting only looked at Fang Sheng. With three pairs of eyes watching, Fang Sheng shrugged and said, "The minority obeys the majority, then try it."

At the flat copper lamp, Yu Xiaoting pushed it back into its original position. It seemed to be blocked when the space of the longest copper bar seemed to be blocked. She adjusted gently, and then returned to her position with three "Prince" sounds.

No response.

Su Ruotong blinked and said, "Do you want to put the big block in?"

"Um."

Yu Xiaoting acted as she said, and turned around in the opposite direction just now for a few times. Then the sound of chain rotation and mechanical opening and closing came from the ground, and the sound became louder and louder.

"We... let's go out first?" Su Ruotong was a little scared.

“The entrance should…”

Fang Sheng said three words, and he couldn't help but sink to the north side of the entire wooden house. The speed was so fast that even Yu Xiaoting didn't have time to react. The four of them lost their balance and rolled into the darkness of the cliff!

"Quixa, there is... something wrong!" Fang Sheng shouted.

Yu Xiaoting responded in a rolling manner: "I can't stop!"

After more than 20 meters, the slope became steeper and almost at an angle of 80 degrees. Four people whistled down at a speed of 100 meters!

"Hold your head!"

Yu Xiaoting struggled and shouted. Fang Sheng and others suddenly woke up and tried to adjust their posture. They raised their arms and protected their heads tightly. At first, their body was hit by the raised stone corners. When the sharp edges were hurt, they still felt pain. Later, they were all over their body, and the pain was numb and there was no feeling. They would rather hit any stone and die, so as not to suffer such suffering...

I don’t know how long I had rolled, but my face hurt so much. I was dizzy. I still kept awake. I wondered why my face hurts. Isn’t it protected me with my arms? Later, not only my face, but my body was trembling with pain. My teeth kept fighting. He shuddered and realized: This is not pain, but cold!

They were slid quickly towards an extremely cold ice cave!

Yu Xiaoting also discovered the seriousness of the problem and shouted desperately in the dark: "Fang Sheng--" and then there was no sound. Fang Sheng wanted to answer, but his lips seemed to be frozen, and he couldn't hold a word for a long time.

"Boom!"

Unexpectedly, my eyes lit up and felt that I rolled to the ground. My body rolled forward for more than ten meters and hit a wall before stopping.

The white cold air was like an invisible net that wrapped the four people in densely, unable to move.

"Fang Sheng, He Chao, Ruotong, are they all okay?" Yu Xiaoting recovered first and asked withstood cold.

"exist……"

"cold……"

"Um……"

Fang Sheng and others were so cold that their teeth were ringing, and they could only barely write a word.

"Stand up! Come with me!"

Yu Xiaoting walked towards the right side with a vague light, and when she got to the front, she found that the dark one was not the stone wall, but the thick and dense tassel vines. Villagers in the Central Plains Mountains hung it on the door to make a curtain in summer, which prevented mosquitoes and cool. Moreover, its leaves were thick and overlapping, which could effectively block the barrier. The few rays of light I just saw were the overlapping gaps of branches and vines.

The eyes became brighter and brighter. When Yu Xiaoting lifted the last layer of wooden vine leaves, everyone shouted "ah" at the same time. Her eyes were so painful that they were pricked by the snow-white light, and she instantly forgot about the deadly cold cold!

I quickly closed my eyes and adapted for a while before I opened it carefully, and then I let out a "ah" at the same time.

In front of me is a round and transparent crystal hole!

The cave wall is a nearly perfect arc, forming a circle in harmony and coordination, which is more precise than the one drawn by a compass. The pure white crystal is composed of large transparent gypsum crystals, crystal clear, bright and refracting dazzling white light.

Su Ruotong was so crazy that she stomped her feet hard that she pulled He Chao anxiously: "Hurry up, pinch me quickly and let me come out of my dream."

He Chao said in a daze: "It would be great if it was a dream. I would pack the entire crystal hole and take it away."

Standing in the middle of the crystal cave, the shadows of four people were shaking around, which looked like illusion and reality, making people feel dizzy that was separated from reality.

Fang Sheng laughed in silence, but he was thinking about the crucial question: With his technical level at that time, how did the ancient Shu people complete this huge and arduous project?

Even liberal arts students know that the hardness of crystals is far greater than that of ordinary gems and jade, and is a hard and solid mineral, but it has two temperaments: one is that it is easy to be fragile when heated, and the crystal melting point is 1713 degrees Celsius. Even if boiled water is poured on it, the crystals are easily broken. The other is that they are afraid of alkali and not acid, which is determined by its silicon oxide characteristics.

These two points make it extremely difficult to dig and process it. In ancient times, sharp steel files were used to repeatedly knock on the cone drill, killing one thousand enemies and destroying 800. Usually, several steel files were needed to process a crystal craft. It is impossible to imagine how the ancient Shu people thousands of years ago completed this almost impossible project in the mountains with the most primitive tools!

Yu Xiaoting pushed Fang Sheng and said, "Continue to walk to the front and take a look. It's strange and abnormal here."

He Chao also calmed down from the fanaticism and said, "It's very evil. If the castle is compared to an ancient tomb, is it equivalent to the tomb corridor in the core tomb chamber?"

The crystal cave highly refracts light and sound. Every time you say a word, it reverberates in the cave like dozens of people talking at the same time, feeling very uncomfortable.

Fang Sheng lowered his voice and said, "There is an echo wall in the ancient tombs of the Song Dynasty. That is used to scare tomb robbers. The crystal cave also has this function?"

Su Ruotong said: "It's a bit unworthy to use such a large crystal to scare people just because it's a bit unworthy. In my opinion, it has other mystery."

"Continue to move forward!" Yu Xiaoting urged, not participating in the discussion.

After walking for more than ten meters, I turned a sharp turn, and there was a crystal wall in front of me blocking the way!

To be precise, it is not a wall, but a door with flowing light and water overflowing. It is about ten meters long, with water-like liquid flowing up and down and reflecting colorful light.

When you touch it with your hands, it feels like you touch it on the crystal, and it is integrated without any gaps.

Four people stood in front of the crystal wall in a row, completely stunned.

The water waves were flowing up and down, and gradually, a person slowly appeared on the wall in front of Fang Sheng, that is,—

Fang Sheng!

I saw myself pursing my lips tightly and looking at the opposite side with a serious face... A person seemed to be sitting opposite the ripples, as if he was talking seriously.

After a while, I seemed to be angry, and waved my arms and asked loudly, with an unprecedented expression of coldness and anger!

The man opposite seemed to be quite familiar with him but couldn't see clearly and could not remember him, so he talked to himself calmly.

In an instant, Fang Sheng caught something faintly and saw it more seriously. However, the water waves of the crystal wall swayed violently, and then caused huge waves, tearing the picture on the wall into pieces, and shattering the shadows on it without a trace.

"Wow", the watery liquid suddenly quickly entered the stone walls on both sides, revealing a black corridor.

Fang Sheng turned to look at Yu Xiaoting and others, but saw that they all looked ahead with confusion and loss, as if... they were all stunned by the scene they saw on the crystal wall just now.

"What should I do?" Fang Sheng asked.

Yu Xiaoting suddenly woke up, took two steps back a little in panic, and said after a while with a look of surprise: "No... we can't leave anymore, we have to go back!"

"Maybe...there is more interesting in front..." Su Ruotong muttered. At this time, her face was full of loneliness, sometimes lowered her head to ponder and sometimes secretly glanced at Fang Sheng.

Yu Xiaoting pointed to the frost condensed on both sides of the corridor in front and said, "It's because of the crystal that it's not that cold now. It's because it's cold. Leaving the crystal cave, it's a fatal killer again!"
