Ling Zhihan nodded gratefully to the general, and then showed a clear smile, looking much more confident, picking up the bronze mirror from the table and carefully examining every detail.

"Don't keep looking at the front, you have to look at the words in the back." Tian Ji hesitated for a long time and said bluntly. "There's nothing on the front, you've been reading it for almost an hour, and the words in the back are the key."

"You know, here you come." I glared at Tian Ji and motioned for him not to disturb Ling Zhihan.

"The ancestor left this bronze mirror in order to convey the clues of the Vientiane Divine Palace, which means that any of the above details may have a mystery." Ling Zhihan replied meticulously.

"She's right, including this bronze mirror, there must be a reason for its existence, if you just want to leave words, you don't need to be specially engraved on the bronze mirror." The palace lord nodded.

"Then the lines on this bronze mirror are not beautiful, there are clouds above, and there is a river below, I think it is for decoration at best." Tian Ji said.

"Why use decoration, the purpose of this bronze mirror is to convey a message, not to look good." I choked on the chicken and said with a frown. "It's just quite strange, the bronze mirror of the Tang Dynasty is very distinctive, and the ornamentation is gorgeous, such as the delicate gold and silver flat mirror, luodian mirror, but the decoration on it is mostly dominated by animal patterns and figures, and it is very rare to have such ornaments."

"Ling Xuan is an earth master, and the clues she left behind are probably related to occult arts." The general had already rolled up his cigarette and put it to the corner of his mouth and said. "You have to think about it."

"The clouds above, the river below, what kind of mystic art is this?" Tian Ji lazily lay on the table and said.

"The clouds are from the dragon, the wind and clouds are surging on the mirror, there must be traces of the dragon, but I have never figured it out, I have not seen any rain falling, why the river below is rippling." Ling Zhihan muttered thoughtfully.

"You say that the clouds are from the dragon, and the wind and clouds will meet, maybe it is the wind that blows the river below." Tian Ji looked up and said.

"Shut up." I pressed the pheasant's head on the table. "Since there is wind, the clouds have long since blown away, and I didn't see so many clouds gathering above."

"The ripples on the surface of the river indicate that there is something wrong, there are dragons in the clouds, and the dragons are prosperous clouds and rain." Gong Jue poked his head over and looked at the bronze mirror and said. "Could it be because of the rain?"

"On the pattern that can be decorated, the clarity of the picture does not mean that it is cloudy and rainy, and it should not be the cause of the rain." Ling Zhihan shook his head and said.

The general just wanted to light the cigarette at the corner of his mouth, his hand hung in the air, and his brows furrowed: "There is no wind and no rain, the river is shaking, maybe there is another reason." ”

"What is the reason?" I asked.

"Gong Jue didn't say that the dragon can prosper clouds and rain, think about it, what will be before the general clouds and rain?" The general looked at me and asked.

"Before the clouds rain?" I scratched my head and thought about it for a long time.

"Thunder." Tian Ji raised his head again.

"Yes, could it be the cause of Thunderbolt." The general nodded.

"It's unlikely, Uncle Wei, have you ever seen thunder in the sky that can move the river?" The palace lord helped light a cigarette for the general.

"Lei ......" Ling Zhihan suddenly stretched his brows, and his gaze fell on the bronze mirror again. There will be no rain in the wind and clouds above, and the ripples in the river below, which should be an allusion to the rolling thunder in the sky, thunder above, water below, thunder on the top and water on the water......"

"Thunder hydrolysis!" I naturally can't compare to Ling Zhihan in metaphysics, but Zhou Yi's sixty-four hexagrams have been forced to memorize me backwards since I was a child.

Thunder hydrolysis is the fortieth hexagram of Zhou Yi, also known as the interpretation of the hexagram, which is the earthquake on the top and down, the earthquake is thunder, and the kan is water, which just coincides with the ornamentation on the front of the bronze mirror.

"In the hydrolysis of thunder, the earthquake is thunder and movement, and the kan is water and danger, and the danger is inside and outside." Ling Zhihan's face was happy. "This hexagram originally said that the land is closed in severe winter, but winter goes to spring, and the static pole moves, and everything is renewed."

"What does it mean that your ancestors left an explanation on the mirror?" Tian Ji has some spirit.

Ling Zhi said calmly, the meaning of interpreting the hexagram is that if you are in trouble, you can get out of the predicament, and the one who interprets the hexagram is.

Southwest Li, nowhere to go.

It means that it is good for the southwest journey, but if there is no definite goal, it is better to return and return to auspiciousness. If there is a definite goal, it is advisable to go early and be auspicious as soon as possible.

"Ling Xuan left the hexagram to say that if it is to find the Vientiane Divine Palace, he should immediately set off to the southwest to find it, and there will be gains." Gong Jue was excited.

"Go southwest,......," I thought and pulled out the map from my bag. Further southwest from Dunhuang is the land of the Western Regions of the Tang Dynasty, so it seems that the Vientiane Divine Palace is really in the Western Regions. ”

"It stands to reason that Ling Xuan asked Li Yuan to help him build the Vientiane Divine Palace, why didn't he pick a convenient place and run outside?" The general took a puff and muttered to himself.

Ling Xuan's words were not unreasonable, Zhuo Mingfeng had said very clearly before, the Vientiane Divine Palace was built on a dragon vein, and it was also a dragon vein that had never been discovered from beginning to end, in order to hide the other two dragon veins that were also unknown.

The ancestor of the dragon vein in Kyushu originated from the Kunlun Mountains, and the dragon veins known to the world are the Kunlun Mountains that continue to the east until they enter the Central Plains, but the northwest of the Kunlun Mountains is the Tianshan Mountains, the Qilian Mountain Range, and the Yinshan Mountains.

However, at that time, this area belonged to the Western Regions, and most of the mountains were inaccessible, and after Ling Xuan found it, he used the Vientiane Divine Palace to town the dragon veins, which may be the reason why the people of later generations did not know that there were still three dragon veins, as Zhuo Mingfeng said.

"This place is not small, the panorama of the Western Regions at that time was large, and there was a sentence on the hexagram, telling us to go to the southwest, who knows where we are going." Tian Ji pointed to the map. "Most of this place is a barren desert, and if you have a life to go in, you can't get out."

"Yes, if you only say to the southwest, you have to say a place to go." The general looked at Ling Zhihan and asked.

Ling Zhihan took the bronze mirror in his hand and pondered it for a long time, and the eyebrows that were still stretched before gradually solidified, and shook his head to tell us that there was no other meaning in all the hexagrams of the hexagram, only that the direction was to the southwest.

"What Southwest?" Ye Zhiqiu's voice came from behind.

When she saw the bronze mirror in Ling Zhihan's hand, her eyes suddenly lit up, and she carefully took it and couldn't put it down: "Where did you find this thing?" ”

I told her everything that happened after she and Song Wenjie left, and of course, the palace lord kicked the mural and I dug a hole in it without saying a word.

"Song Wenjie, he, he didn't say anything?" I asked tentatively.

"What can he say, when he leaves, he said thank you, or Uncle Wei's atmosphere, and I am relieved that the picture scroll is said to Wen Jie, and it can be regarded as filling a gap in the archaeological history of Dunhuang." Ye Zhiqiu said.

"Didn't you go back to the grotto?" Tian Ji asked with palpitations.

"I went, I saw that the iron door was closed outside, I thought you had returned, so I returned with Wenjie."

I breathed a sigh of relief when I heard this, and I guess no one will go to the grotto in a year or two, and if there is trouble, it will not find us.

"Since the Vientiane Shrine is in the southwest of Dunhuang, there should be a hint on this bronze mirror." Ye Zhiqiu looked at the bronze mirror and said.

"Could it be that the exact location is on those inscriptions behind the bronze mirror?" I say.

Ye Zhiqiu flipped the bronze mirror over, his eyes became a little surprised, and he reached out to touch the inky black jade inlaid behind the bronze mirror, which was as black as ink, heavy and greasy, with a fine texture, smooth and elegant.

"This jade ......"

"Don't look, this is Moyu, a precious variety of Hetian jade." I interrupted Ye Zhiqiu and said disapprovingly.

"Look at what you can, as far as you know, this is Moyu." Ye Zhiqiu glanced at me, turned around and closed the curtains of the room, and then covered the inlaid ink jade in the palm of his hand, and in an instant, a dazzling light emanated from the jade.

"Gobi Moyu ......" I was stunned and taken aback.

"What is Gobi Moyu?" Tian Ji asked curiously.

"As the name suggests, this jade is produced in the Great Gobi, after hundreds of millions of years of wind, frost, snow and rain, the jade quality is very good, black as pure lacquer, as fine as mutton fat, is the best in black jade." The general took off the cigarette from the corner of his mouth, and his expression was a little excited. "But Gobi ink jade is really hard to find, especially this kind of superlative, this thing is a rare treasure, it is said that the top Gobi ink jade can shine at night, so it is called luminous ink jade, I didn't expect that there is really such a jade."

I really don't dare to compliment Ye Zhiqiu's appreciation, even I didn't realize that this jade turned out to be glow-in-the-dark ink jade for so long, she actually knew it at a glance.

"You, how do you tell?" I asked, confused.

Ye Zhiqiu proudly held the luminous ink jade in his hand and said, according to legend, in the west of Xiaofang City, there is a post station called Ma Lost, where the swamps are all over, the ravines are vertical and horizontal, the forest covers the sun, and the weeds are overgrown, and the caravan from the border to the Central Plains to transport jade from Khotan has to pass through here, and it is always impossible to distinguish the direction, even the old horses who often go back and forth on this road will be dizzy, and it is difficult to know the way.

Later, someone put a luminous dark green jade, inlaid on the top of the small square city gate, whenever night falls, this piece of jade will emit a dazzling light, a radius of dozens of miles away can be seen clearly, the past caravan has a goal, no longer get lost.

"I originally thought it was just a legend, but I didn't expect that there really is such a magical jade." Ye Zhiqiu said.

"Where is Little Square City?" Tian Ji asked.

"Why don't you know anything, you haven't heard of Xiaofang City, haven't you heard of Yumen Pass." Ye Zhiqiu's mind was all on that black jade, and he replied impatiently. "Xiaofang City is Yumen Pass."

"Yumen Pass?!" I raised my head abruptly and took the bronze mirror from Ye Zhiqiu's hand. "The bronze mirror of the Tang Dynasty is rarely inlaid with jade in the back, and this bronze mirror is inlaid with a rare and precious Hetian ink jade, which should be a reference, and the Hetian jade imported from the Western Regions is because it passes through Xiaofang City, so it is named Yumen Pass."

"It's good to go southwest,......," Ling Zhihan hurriedly looked at the map on the table. In order to go southwest, you must pass through the Yumen Pass! ”

Gong Jue was suddenly stunned and slowly stood up, his expression was very shocked, and the corners of his mouth squirmed: "Do you still remember what Zhuo Mingfeng said before leaving." ”

"He said to see the scenery, let's figure out how to unlock the secret on the bronze mirror ourselves, and then tell him." Tian Ji was uncomfortable when he mentioned Zhuo Mingfeng. "We've been meditating all day here, and he's better to go on a tour of the mountains and rivers and wait for the results."

"That's not it, it's the first sentence." The palace lord shook his head.

"The first sentence?" Tian Ji looked at Gong Jue in amazement. "What was the first thing he said?"

"I remember, Zhuo Mingfeng's original words at that time were, a lonely city of ten thousand mountains, this Dunhuang has a lot of exotic customs, since you came, don't spoil the scenery, wait for you to unravel it and tell me." As soon as Ling Zhihan finished speaking, his expression immediately became exactly the same as that of Gong Jue, and his eyes were full of surprise. "A lonely city and a ...... mountains"

Ye Zhiqiu and I were also dumbfounded, and the room fell silent in an instant, Tian Ji looked at us blankly, and it took a long time before he asked: "This, does this make you react so much?" ”

"This is Wang Zhilian's "Liangzhou Ci", do you know what is behind the sentence "A lonely city and ten thousand mountains?" The general took a deep puff of cigarette and looked solemn.

Tian Ji's honest expression was still dazed, this was originally a popular poem, but when it came out of Zhuo Mingfeng's mouth in the grotto, it had a completely different meaning.

Why should Qiang Di complain about the willows, the spring breeze does not pass the jade gate.

……

Zhuo Mingfeng's words were light-hearted, seemingly casual, but he only glanced at the bronze mirror, and he cracked the secret on the bronze mirror at that time, and from that time on, Zhuo Mingfeng already knew that the location of the bronze mirror was in Yumen Pass.
