"You're saying that the Xuanyuan Sword that defeated the Chiyou tribe was made in this country." Jin Yinan asked curiously.

"Xuanyuan is a general term for a weapon, and it does not necessarily refer to a sword, perhaps more advanced." Professor Li replied.

"You notice the steps under your feet." Bai Ruifeng looked at the stone steps under his feet and said, "Have you noticed that these stones don't look like they are polished by hand, but cut by some kind of equipment?" ”

"That's true, listening to what the teacher said, it's really like this." Xiao Wei took out a caliper and measured a few stone steps, "Each stone step is 33.33 cm, and the error is ± 0.00001!" This is something that even laser cutters can't achieve now. ”

"We are facing a civilization that is far beyond our contemporary civilization." Bai Ruifeng said silently.

Half an hour later, in front of the temple at the top of the tower, Yan Yun and the three young people watched in confusion as the four elders bowed silently to the stone pillar in front of the temple.

Looking at the teacher and they walked towards the temple gate, Xiao Wei asked curiously: "Teacher, why are you bowing to that stone pillar, is it a religious ceremony?" ”

"That's where Professor Yuan Hemu disappeared." Bai Ruifeng muttered.

"What?" The three of them said in surprise.

"My teacher was there, and he disappeared before our eyes." Bai Ruifeng shook his head and said.

"In other words, you've been here before, teacher?" Qiu Hai's eyes widened and he said.

"Yes, we were here 10 years ago." Bai Ruifeng looked at his students and said, "But at that time, only Professor Yuan Hemu had entered here. He went in alone while we were sleeping, and when we found him coming up alone, we chased after him, and when we arrived here he came out just in time, shouting to warn us not to go in, and then disappeared in front of us. ”

The four warriors laboriously pushed open the door of the temple, and assembled the military searchlight at the gate, and when the light was turned on, everyone was stunned by the scene inside, the hall was full of animal bones and human bones, and weapons scattered everywhere, including ancient bows and arrows, as well as modern firearms. In the center of the hall was a large stone statue of a dignified beauty, holding a lotus pot in one hand and a scepter in the other, the tip of which was inlaid with a ruby the size of a watermelon and shimmering like a ghostly light.

"Who is this woman? Why is her lower body snake-like? Xiao Wei looked at the stone statue and muttered, "Is she the legendary Nuwa?" ”

"This is a stone statue of the Queen Mother of the West." Professor Huang walked to the edge of the stone under the stone statue, looked at a line of oracle bone inscriptions, and said.

"Queen Mother of the West?" Several young men gathered around. "Are you talking about the Queen Mother of the West who went to Wushan with King Zhou Mu?"

"Yes, that's her." Professor Li looked at the bones on the ground and said, "This is the legendary Wushan. ”

"How is it possible, this is a desert, where does the mountain come from?" Jin Yinan said in disbelief.

"How did you know this was a desert 5,000 years ago?" Professor Li replied, "Look at this kind of stone, this is the black stone recorded in ancient documents, the unique stone of Wushan. Professor Li took the small stone hammer in his hand and gently knocked on the pedestal stone, and the stone made a clanging sound that only metal can have. There is actually a whole mountain buried under this desert. ”

"Haven't you noticed that the buildings here are different from other Western Desert ruins?" Bai Ruifeng said behind them, "The buildings at other sites are mostly made of poplar wood mixed with sand, but the buildings at this site are all made of monolithic boulders. ”

Yan Yun circled around the hall and shook his head in great confusion.

"Master Yan, have you found the entrance?" Bai Ruifeng looked at Yan Yun who was walking towards him and asked.

"No, it's a confined space, and I don't feel the slightest sense of a spatial rift." Yan Yun shook his head and walked in front of Bai Ruifeng. He looked up at the statue of the Queen Mother of the West, "Can you take out Yuan Hemu's note and show it to me now?" I always felt that the key to opening that entrance was on this stone statue. ”

Professor Huang took the spectrum analyzer and looked at the huge ruby on the scepter, "This is not any gemstone we know, it has a spectrum beyond all known gemstones. There are 81 kinds of spectrum! Professor Huang said in horror. It...... It...... Its quality ...... Up to more than one million tonnes ......"

"How many tons?" Several people immediately gathered around Professor Huang.

"I can't measure it, it's beyond the range that this instrument can measure." Everyone's eyes widened as they watched the number of the instrument show out of range.

"Professor, is this thing broken?" Qiu Hai said.

"No way, this instrument was imported for more than 100,000 dollars, and there is no bad record until now." Professor Huang said categorically.

"You're saying that stone has 81 spectrums?" Yan Yun frowned and looked up at the gem on the scepter.

"Yes, that's what it says on the instrument." Professor Huang looked at Yan Yun and said.

Yan Yun took out a feng shui plate from his backpack and placed it directly below the gem, and the hands of the feng shui plate suddenly rotated rapidly.

"I know what it is." Yan Yun snorted and said faintly, "This thing is indeed not a gem, it is a mountain spirit." Looks like we've almost found the entrance. ”

"Mountain spirits? What is Mountain Spirit? Xiao Wei asked puzzled.

"Mountain spirits? By the way, this thing is indeed a mountain spirit! Professor Huang suddenly said cheerfully. There is a record in the "Classic of Mountains and Seas", but no one has found a physical object for so many years, and they all think it is a myth. Professor Huang said excitedly.

"Generally speaking, the mountain spirit is the spirit of the mountain, a crystallization formed by great pressure, with great density and weight. It is neither stone nor gold, and its density is estimated to be more than ten times that of platinum. Master Chen raised his head and stared closely at the red crystal that glowed with a strange light and said. When I was studying in Rosa, I participated in a geological expedition, and it is said that such a thing was dug up in a mountain in the Ural Mountains at that time, of course, as international students, we were not allowed to work in the core area, I only remember that it was very small, maybe the size of a fingernail, but they brought in a giant crane and a giant transport truck with 280 wheels to lift and transport this thing, and soon the mountain that dug up the crystal collapsed. ”

"If something so heavy and so dense could move in such a small space...... Bai Ruifeng said.

"Then the space will be distorted." Jin Yinan's eyes widened and he said.
