After three turns and two turns, Qin Zhen found that they seemed to have gone around the inner city. Vaguely visible that there are corner towers at the four corners of the city, there are enemy towers in the middle section, and there are urn cities on both sides, and the city towers are symmetrical. It's not hard to imagine how majestic it once was. The castle tower has three floors and is surrounded by corridors, but I don't know if it can still be passed. The road leading to the top of the city has collapsed and is buried by yellow sand, and the loess brick wall is in ruins, making it a desolate and depressed scene.

The only thing that doesn't match this environment is the cold light of the black jade on the top of the city that you can see when you look up now. It was only at such a close distance now that Qin Zhen really saw the legendary top of the city. I don't know what kind of building it is, but if you look at it from the outside or from a distance, you don't think the top of the castle is very high, but it seems to be a normal height. However, now that I am under the castle tower and look up, I realize that this castle tower is not ordinarily tall!! At first glance, it almost has to be 14 or 5 meters! But when they were outside, they did not see such an abrupt tower. This made Qin Zhen puzzled. So he patted Yudong on the shoulder and asked, "Don't you think it's strange that this city is tall?" ”

"I don't think so. Is there anything wrong with this? Yu Dong asked rhetorically.

Qin Zhen deeply felt that he and Yudong definitely belonged to people with completely different thinking logic, but after thinking about it, he still said patiently, "When we looked at the Yumen Pass from the outside, we didn't see such a tall building!" ”

Yu Dong looked at Qin Zhen disapprovingly and replied, "When there is no wind and sand, can you see this Jade Gate Pass?" In my opinion, this tall tower is not only not strange, but more commonplace. ”

After listening to Yu Dong's words, Qin Zhen looked at Yu Dong even more confused, waiting for him to continue to explain. I heard Yu Dong say, "Although the age is too old, how can I say that this is also the westernmost pass of the Han Dynasty." It is a necessary pass for the Central Plains and the Western Regions, and it is also an important military pass and a place for troops in the Han Dynasty. So there's no reason for it to be as crude as Little Square Plate City. Even if it can't reach the Jiayu Pass and Juyong Pass, and the walls are tight, at least as we see now, there are all kinds of military facilities such as arrow towers, enemy towers, and corner towers. ”

With Yu Dong's pointing, Qin Zhen seemed to understand his words a little. But then he was still a little puzzled and pointed to the city tower and said, "Look, this is like the Chenghai Tower on the old dragon head of Shanhaiguan, but the old dragon head is entering the sea, what can you see here?" Do you see the wind and sand raging? ”

"The sea of sand is also the sea. This place has been a place of war since ancient times, and the higher the tower, the more it is helpful to look out at the frontier of the Western Regions. Okay, this is not the place to talk, that side is the west wall of Yumen Pass, let's go over and see if there are any clues, and then go up to the city tower. Yu Dong still said quietly.

But Qin Zhen looked at the towering city tower in front of him with some embarrassment: "These more than ten meters high city tower, do we want to climb it with our bare hands?" In fact, this is not too much, because the road to the top of this castle tower is obviously no longer there, and there seems to be no other way to go up than to climb.

However, Yudong didn't seem to pay attention to Qin Zhen's question, and instead walked straight towards the west wall. As the flashlight flickered across the city wall, Qin Zhen was surprised to find that there were mural texts on the city wall!

This is unheard of! The military powerhouse has always been majestic and majestic, how can there be such a poetic thing? Yudong was also a little surprised when he saw the mural for the first time, and then carefully observed the mural and thought about it. Qin Zhen didn't bother him, but also stepped forward to carefully inspect the murals on the city wall in front of him. Without exception, all of them are from Buddhist legends.

Qin Zhen couldn't help but take a deep breath, "In this battlefield place, there must have been a tragic scene of rivers of blood, and painting Buddhist murals here is really indescribable." What did the person who did this mean in the first place? Buddha and demon in a thought? Or is it for the heroic spirits who died in battle? ”

Yudong on the side just shook his head, thought for a while, and then said, "Whether this mural is from the same period as Yumen Pass, we can't confirm it yet." However, the period when Buddhism was introduced to China was roughly during the Han Dynasty, and the Northern Buddhism was divided into two routes, land and sea, and the land route was introduced to China from India through the Silk Road through the countries of the Western Regions. Therefore, the Western Regions is also the first region to come into contact with Buddhist culture. ”

Qin Zhen didn't seem to understand it, anyway, he generally understood that Yudong meant that there was nothing abnormal about the appearance of Buddhist murals here. Looking at the vague and illegible characters on the side, Qin Zhen asked, "This is a Buddhist text, right?" ”

Yu Dong looked at it carefully, nodded and said, "Well, Sanskrit." ”

"Do you understand?" Qin Zhen asked tentatively.

Yudong shook his head regretfully, "I don't understand." This is not the well-known Devanagari script. It is more like the ancient Sidham, and the oldest source should be the Ashoka inscription of the third king of the Mauryan Dynasty, Ashoka."

Qin Zhen said with some frustration, "I don't know what the king is, but I finally found something useful, and it turned out to be something I couldn't understand!" It's really harder to find this clue than to climb to the sky! By the way, what time is it? How long is sunset? ”

Unexpectedly, Yu Dong didn't care about Qin Zhen's reminder, but stretched out his slender fingers to rub the ancient text, and said to himself: "There are two kinds of writing in the era of Ashoka of the Mauryan Dynasty, one is Sanskrit, and the other is Lu Wen, and the large number of written relics stolen by Stein from Lop Nur in the early years are Lu Wen, does this mean Loulan, Jingjue, Khotan, and it's not right" Yu Dong analyzed to himself, frowning quite anxiously, it felt like he was trying to piece something together, but he couldn't put it together

Qin Zhen saw Yu Dong's tightly knit brows, so he had to pat him and comfort, "Don't worry, take your time." At least we've got some connections and clues, aren't we? I'll study the rest with you when I get back! Now we have to find Gu Jie and them first, and then go up to the city tower before sunset. ”

After listening to Qin Zhen's words, Yu Dong's tightly knit brows relaxed a little, and after listening to his 'um' sound, he took Qin Zhen to the side of the passage. But at this moment, the sound of Si Si Suo began to appear on both sides! Qin Zhen couldn't help but feel nervous in his heart, was this the owner of that weird footprint, or the group of weasels that had become essences? When Qin Zhen saw the faint green little eyes around him, he immediately realized that they were in danger at the moment!

This time, these brutes have more 'weapons' in their hands! Qin Zhen gritted his teeth and scolded secretly, this is too humane, right? They all know how to copy guys? It may be an exaggeration to say that it is a weapon, but it is still okay to use it as a weapon. They were all sharp deadwood or iron tools, similar to the sharp blades in the traps before. Of course, Qin Zhen didn't have the time to figure out where this group of beasts moved from at this time, the enemy was outnumbered, and it was important to flee for his life now!

At this time, Yudong quickly buckled the rope on Qin Zhen's body, which is the kind of mountaineering and rock climbing extreme sports. Then, without saying a word, he jumped and climbed onto the city wall. Qin Zhen was dumbfounded when he opened his mouth wide! I saw that Yudong took advantage of the uneven wall on the city wall, as light as a cat, ignoring gravity, and with a gorgeous and demonic figure, he jumped up the city wall of more than ten meters in a few clicks!

Then he turned over and fixed the zipline at that end over the wall, if his end was fixed, then Qin Zhen only needed to press the switch on this side, and the rope could directly bring Qin Zhen to the city tower!

But at this time, the sand ferrets seemed to see that Yudong's departure was a good opportunity to start. decided to be Qin Zhen a soft persimmon pinch. A group of small eyes began to try to move, Qin Zhen immediately sweated when he looked at this strange scene. He hesitated what to do, he couldn't run, let's fight! As long as the device is fixed on Yudong's side, you will be able to get out immediately!

Qin Zhen thought so, but the group of sand ferrets collectively began to retreat. Qin Zhen was startled, thinking to himself that this group of beasts would have to rush up? When he understood the true intentions of this group of sand ferrets, he couldn't help but feel a chill in his heart. They don't want to run, but they want to throw a sharp weapon after a distance! Qin Zhen secretly complained in his heart, he originally wanted to fight in close combat, but who would have thought that this group of cunning brutes was planning a long-range attack! After this dense sword-like iron weapon flew over, he still had to become Yang Qilang?

Before Qin Zhen could react, the group of little green eyes suddenly became fierce, and then they heard a whooshing sound flying towards them! With the city wall behind him, Qin Zhen had no way to retreat at all! At this time, I had to grit my teeth and close my eyes, and subconsciously raised my hand to prepare to block the flying weapon!

However, after countless swishing sounds, Qin Zhen didn't feel the pain of the blade piercing his skin, could it be that the strength of this group of beasts was not enough? Qin Zhen slowly opened his eyes, but saw that Yu Dong didn't know when he had come down, and at this time, he was propping his hands on the city wall, blocking in front of him!

That handsome face was still cold. Qin Zhen just wanted to say something, but Yu Dong ordered in a deep voice, "Go up quickly!" Immediately before the sand weasel sent out the next round of attacks, he pressed the rope device on Qin Zhen's waist, and Qin Zhen was instantly taken to the city wall.

After turning over and jumping into the city tower, Qin Zhen hurriedly and anxiously lay on the city wall and shouted, "How are you!" Hurry up! The flashlight shook over the scene below, and Qin Zhen couldn't help but feel a chill. Groups of sand ferrets surrounded Yudong not far away, but this man was not ambiguous at all, I saw Yudong raise his gun at this time, and turn around to shoot!

After defeating a batch, the sand ferret behind did not flee in a hurry, but stared at Yudong more fiercely than before! Think of the sight of the sand ferret crashing into the eye of the storm, and these beasts seem to be born with a fearless spirit that is not afraid of death.

Yudong didn't dare to fight, taking advantage of the deterrent effect brought by the bullet to the sand ferret, he hurriedly turned around and jumped onto the city wall, and once again climbed the city wall with that godly body. Qin Zhen was sweating profusely, and he kept stretching out his hand to pull Yudong. It wasn't until he grabbed his hand and pulled him across the city wall that Qin Zhen breathed a sigh of relief.

Yudong also sat by the city wall panting, his face a little pale. Qin Zhen looked at Yudong gasping for breath, and quickly reached out to pat him on the back shoulder, wanting to give him a smooth breath, but the tentacles were sticky! Qin Zhen was startled, and hurriedly withdrew his hand and shone it with a flashlight.

When he looked at his hands covered with red blood, Qin Zhen's voice was a little unnatural, "You, you're injured!" Thinking of the scene when the sand ferret launched an attack just now, Yu Dong blocked in front of him, Qin Zhen seemed to understand. Not only is the strength of those beasts enough, but they are enough to hurt people!

Qin Zhen was at a loss for what to do, and secretly shouted in his heart that Lan Qing would be here! What should you do with this bloody brother?

Seeing Qin's shocked and panicked appearance, Yu Dong said in an arrogant manner, "Don't panic, I'm fine." Jiang Qi must have heard my gunshot just now, and he naturally knew which direction to look for me. It's almost dusk, we need to hurry. With that, Yudong gritted his teeth and stood up.
