All of a sudden, everyone's eyes converged on the small paper roll in Zhou Dingxuan's hand. Zhou Dingxuan carefully stretched out the note, only to see that there was such a sentence written on it: "Through the Eternal Sea, you will find the intersection of the hidden city, point in according to the map direction, don't take a detour, there are many dangers, be careful." "Look at the handwriting, this is Xie Haidong's handwriting. Behind the note is a hand-drawn miniature map. Ye Ya was used to seeing military maps, and after he saw that map, he felt a "sigh" in his heart, and gasped and said, "This is a death labyrinth." I saw that in the map, all kinds of roads are entangled, and at the junction of the two roads, they are often marked with a big red ×, and a skull is marked next to it, plus two small words "danger". The point in the middle is marked with a bright red star, where there are three small letters that read: "Destination", and a blue line that runs from a corner to it. Ye Ya estimated that this should be the route given by Xie Haidong. But the sharp-eyed Ye Ya had already discovered that on this route, there were as many as four places where the big red × were drawn.

Ye Ya's scalp was faintly numb, what kind of danger did these solemnly marked red × represent? He was worried in his heart, and he was even more uneasy, where did all those lost A-guards go?

Suddenly, Gu Fengchun and Liu Wensheng shouted in unison: "It's not good. As soon as Zhou Dingxuan and Ye Ya looked up, they saw that the huge waves above their heads that had turned into a dark blue sea level were pouring towards them.

Ye Ya's face changed greatly, and he asked urgently, "What should I do?" "In this flood of water, everyone felt a lot of pressure. If this flood is rushed, they will surely die.

Zhou Dingxuan was still calm, and responded calmly: "I think it will be fine, the Eternal Sea must have its special features." Before the words fell, the water rushed to the side of the four people, and all of a sudden, everyone felt as if their bodies were swept away by the waves, and for a while, Liu Wensheng was the first to faint, only Ye Ya struggled and struggled, he felt like he was being put into a centrifuge, constantly rotating, and finally his eyes were black and unconscious.

"Wow~" I don't know how long it took, Ye Ya woke up faintly, the first thing he did after waking up was to vomit wildly, and after vomiting, he found that he was leaning against a stone wall, and he found that they were lying on a long road, with a height of four or five meters above their heads, and a width of about ten meters. Gu Fengchun, Zhou Dingxuan, and Liu Wensheng were all scattered around him.

He wanted to stand up and look at the situation around him, but he didn't expect that his feet were so soft that he couldn't stand up. Ye Ya was shocked, knowing that his physical strength had been very depleted, so he had to lie half-lying, reached into his backpack and took out a piece of dark chocolate and ate it to replenish his calories. After a while, he struggled to climb up against the stone wall; After taking another concentrated nutritional pill, his pale face gradually returned to normal. Ye Ya slowly approached Gu Fengchun and shook him, Gu Fengchun "hummed" and couldn't open his eyes. He vomited filth and stinky in a coma, Ye Ya frowned, wiped Gu Fengchun's face with his sleeve, took out another concentrated nutritional pill from his backpack, put it in the kettle and melted it, and fed it to Gu Fengchun little by little to drink. A pill the size of a fingernail like this contains enough nutrients and calories for a person throughout the day. This is a military food researched in the W Bureau, which is convenient for the troops to carry.

Gu Fengchun coughed a few times, and drank Ye Ya's kettle in a daze. Ye Ya let go of him and went to take care of Liu Wensheng and Zhou Dingxuan. Ye Ya knew that everyone was fine, but the physical consumption was too great, and it was just that he had passed out, and after replenishing a little energy, he would wake up soon. It's just that Ye Ya felt very strange, the huge wave obviously swept away his group, how could everyone appear here, and there was no trace of water on his body. When Ye Ya woke up, he found that the light source on his body had failed, but the surroundings were soft and bright, he looked around carefully, but did not find the source of these lights.

After a while, Gu Feng let out a faint "ah" and woke up. At this moment, he had a splitting headache, he couldn't help but hug his head, then slowly let go of his hand, looked around, saw Ye Ya was pouring water on Liu Wensheng, and asked in amazement: "Ye Ya, what is this place?" ”

Ye Ya turned around, pouted at him, and said, "I don't know, you woke up just right, it's nothing serious, come and help me feed some water to Professor Zhou." ”

Gu Fengchun nodded, but when he wanted to sit up, he realized that he was powerless. I felt like I had passed a serious illness, and I had no strength left in my body.

"I couldn't get up, I didn't seem to have any strength at all." Gu Fengchun shook his head and said. He looked at both sides, and he froze for a moment, and he shouted: "Mural, not relief, good guy......" Gu Fengchun didn't finish speaking, and struggled to climb to the stone wall, trying to see it clearly. Just now he complained that he didn't have the strength, but after seeing the things on the stone wall, he crawled and approached the other side of the stone wall. It was so angry and funny to see Ye Ya.

This is not a fresco, but a magnificent relief. The pictures on the two stone walls are endless, and Gu Fengchun's eyes are tightly attracted by these pictures. Ye Ya followed Gu Fengchun's actions and also saw the murals that he had not noticed. Although he is a layman in archaeological work, he has followed Gu Zhenting for many years and knows that the historical value of these reliefs cannot be compared with money. The information contained in it may be of great help to them.

Ye Ya was not attracted by the relief in front of him like Gu Fengchun, he fed Liu Wensheng and drank the water mixed with nutritional pills, and then he had to take care of Zhou Dingxuan.

Gu Fengchun slowly stood up while looking at the relief.

Since the stone of the stone wall is limestone, it itself is prone to weathering and peeling. Therefore, the picture engraved in it has become obscured due to the passage of time.

Gu Fengchun looked very slowly, he had to carefully figure out the meaning, and soon Gu Fengchun realized that if he wanted to finish studying the content of the mural, it would not be completed in a moment, he could no longer describe his mood in words, but he knew that the age of some reliefs was very old, and the content inside made him even more confused and shocked.

In the period before writing, one of the most intuitive ways to record the life information of the ancients was the paintings left by the ancients on the rock wall.

The first thing that shocked Gu Fengchun in these reliefs was its scale. Because Gu Fengchun has already felt that the history of the relief on this stone wall has surpassed the recorded history of mankind, as for how long it is, he can no longer feel it, and he secretly estimates in his heart that these pictures in front of him have existed for at least 7,000 years. Fortunately, the environment inside the cave has not changed much, otherwise these reliefs would have already peeled off completely. Seven thousand years ago, what tribe had the leisure to dig out these things out of stone? For this question, Gu Fengchun knew that he couldn't find an answer in his life, but Gu Fengchun was more concerned about why these people spent so much effort carving these pictures? However, Gu Fengchun's thoughts in his heart were very consistent with Ye Ya's thoughts: the contents of these reliefs might be able to help them get out of the predicament in front of them, because the ancients were able to carve a large number of pictures here, and there must be a safe way to get here, but the map brought by Zhou Dingxuan did not indicate where their retreat was.
