But when he arrived at the destination excitedly, Xu Wen and the others were stunned. The Jingbian River is not only a scenic spot, but also a revolutionary memorial site. The roads and greening are well repaired, with many tourists, and the scenic spot is also quite grand. There are memorial halls, former residences of celebrities, and statues of revolutionary great men. However, the real core attractions are a row of caves dug among the thick loess, and the "former site of the expanded meeting of the Xiaohe Front Committee".

Looking at the entire scenic area, it would not look like there were any other relics. Xu Wen, who was stunned, did not give up. After brief discussions with Shen Yingjie, the two of them took action separately. Shen Yingjie followed the tour group and contacted the tour guides and scenic spot managers to see if they could collect useful information. Even if there were any problems, Xu Wen quickly left the scenic area. He wanted to check the terrain outside and find locals to understand the situation.

The Jingbian River is surrounded by a typical Loess Plateau landform, with endless loess slopes, ravines and sparse vegetation. Except for the sporadic rural greening, the land in the rest of the scenic area is relatively barren. Xu Wen selected several high points to look out from a distance, which was disappointed every time, and was incompatible with the background of the picture. He then asked the villagers to find out the situation. He had never heard of the Qing army stationed in, and even the Qingyun Business Name.

Shen Yingjie had no gains. After the two met, they decided to leave the tour group to Tongwancheng, which is the most famous scenic spot in Jingbian. To put it bluntly, it is an ancient city ruin. It is said to be the only capital ruins left by the ancient Huns.

Because the two of them delayed their moments in the county town, their itinerary was the opposite of the tour group. They went to Tongwancheng first before coming to Jingbian River, so they had to act alone.

But after going to Tongwancheng, the two of them were both disappointed. The ruins were quite large, but they were excavated around them. They talked to the old people in the scenic area. The old people had never heard of Xu Wen's concern. Moreover, the terrain here is flat like the eastern plain. At a glance, the scenery is full of sight. The Yinshan Mountains in the distance are more like the earthen ridge fence next door. From any angle, they cannot match the background in the picture.

Because of the long-term weathering, the ruins of the city walls are like large mounds, piled up in the east and west on the loess plateau without any rules. If you look at them from the perspective of historical aesthetics and visiting, you will definitely be amazed by the ancient cities a thousand and six hundred years ago. The white walls are all pure rammed earth buildings, with horse faces, and towering corner towers seem to silently tell the history of the long-stolen gold spear outside the border.

But Xu Wen and Shen Yingjie were not in that mood at the moment. It seemed that the instructor decided to give up Jingbian. Except for the terrain that did not meet the conditions, he could not tell what other truth was. It was already night when they returned to their residence in Yulin. After a brief wash, they found a nearby night shift for dinner.

"Where will be next?" Shen Yingjie asked.

"The Urat front flag is used to chew all the way from west to east." Xu Wen quickly adjusted his mentality on the road, but just three days have passed, and he is really impatient to find a needle in a haystack.

"Or why we connect the coordinates of the five locations into lines, look at the shape of the geometric figures, and find the outermost rectangle or triangle." Shen Yingjie did not agree with Xu Wen's stupid method, but it was not convenient to object directly. He always felt that it would be better to do his homework first.

"what you up to?"

"Calculate the golden division point and find the division line."

"Haha, the heroes have similar views." Xu Wen smiled, reached out and took out a piece of white paper from his pocket, unfolded it and handed it to Shen Yingjie, "It's really a loss for the industry to not be an archaeological team member. You can see where this point is first. Because there are no accurate parameters, you can only guess and calculate it, so you don't have much grasp. It's better to exclude the points on the outside one by one."

The white paper is a hand-drawn map. Xu Wen had already made connections between five locations and calculated the largest rectangular golden division point. It was actually in the middle of the Yinshan Mountains. Shen Yingjie understood that what Xu Wen said was not very sure, not because he did not trust the five points given by the instructor. Dingbian and Jingbian were eliminated one after another, and the basic parameters lost their meaning. The golden division point calculated in this way was inaccurate at all.

In addition, why should we use golden points be used? Shen Yingjie only relies on one feeling, which is the aesthetic value theory of ancient Greek philosophers. He believes that most people will unconsciously pursue the beauty of specific proportions when they appreciate things. This specific proportion is the mysterious golden points, which is a psychologically unconscious suggestion of beauty. For example, the ratio of height to the side length of the base is close to 0.618, and many beautiful buildings are the same, and the beautiful human bodies are also.

Then, the legendary Zhang family guarded the royal treasure more than 200 years ago, and its burial location should also follow the logic of golden division with a certain reference object.

Xu Wen's understanding of the golden segmentation point is more thorough. He agrees with the unconscious origin tracing theory of human beings, that is, the golden segmentation point may imply a congenital visual recognition ability of human beings, which is gradually precipitated by the long-term influence of the natural environment.

Based on this hypothesis, after obtaining the information, Xu Wen had arranged different combinations of five points on the map and calculated the largest golden segmentation point of the similar quadrilateral.

Shen Yingjie blushed. If he had known Xu Wen had considered this, Zhou Xiang would not speak. Since experiencing a series of cases in eastern Guangdong, she has become a little unconfident. Especially the things she experienced with Li Tianqiu seemed to have allowed her to see another unreal world. Li Tianqiu's change was too fast, making her overwhelmed. He and his opponents were suddenly incredibly powerful. Is it because of technological means, or were they affected by some external force, or were they from another world? She was very frightened by this sudden idea.

In fact, Xu Wen did not tell Shen Yingjie a little about it. He calculated the golden divisions of the ferocious beast's avatar on the antique picture, but none of them had a ratio of nearly 0.618. This result scared him. It shouldn't be true, because it was based on Xu Wen's eyes observing the ferocious object, which naturally meets the conditions for human identification and traceability. But the fact is not the case. It can only show that there is something wrong with this painting, which is extremely weird and weird. I don't know where the Zhang family got it. Will this painting not belong to this world?

The two of them were silently stuffed with food, each of them was stuck in their horns, and they didn't say a word for a long time until they wiped out all the skewers on the plate.

"Will the mountains on the background of the pattern be the Great Green Mountain?" Xu Wen suddenly asked. His thinking was extremely jumping at the moment. He had just climbed out of the horns and circled around Er'erqi. Before he could go to the front flag of Urat, he had already thought of Wuchuan Town.

"I don't know, but I also think that the chance of searching along the Yinshan line will be greater." Shen Yingjie's thoughts were the same.

"Yes, the instructor casts a net all over the sky, let's focus on fishing." Xu Wen slapped his thigh, "But I still have to go to the front flag of Urat."

"For the water waves on the background on the picture?"

"It cannot be ruled out. If you have too sloppy strokes, you can't figure out whether it is a Hubo or a river. You will feel relieved after seeing it." Xu Wen was even more cautious. The Urat front flag was too far away, so it was not easy to travel.

The two set off early in the morning. This time, they did not sign up for a tour group, but rented a car and could return it from another place. The base camp is inconvenient in Yulin, so they moved north to Baotou or Wuchuan.

However, the trip to the Urat front flag still disappointed Xu Wen and Shen Yingjie, and no valuable news was found. Moreover, the endless meadows and the vast Wuliangsuhai obviously could not match the background of the pattern on the mobile phone.

The two spent almost a day wandering around the former site of Guwoye Town, taking pictures from different angles, drawing a stack of sketches, comparing them repeatedly, and finally denying them one by one, finding nothing, but enjoying enough of the scenic scenery of going west to Yangguan. When they climbed onto the car tiredly, it was already the sunset in the long river.

"Did you notice something is wrong?" Shen Yingjie felt uncomfortable since the afternoon. He subconsciously thought that something was peeping at her. On the way to get on the bus from the old town, this feeling suddenly disappeared.

"It doesn't matter, be natural." Xu Wen obviously noticed it. He was silent and did not remind his companions. He quickly recalled the situation around the ancient town ruins in his mind. There were not many tourists in the afternoon, but there were always people nearby in groups of three or three, but there were no special people who were deliberately approaching. They were all ordinary tourists. They took photos and strolled around, and they couldn't find any obvious unusualness.

Xu Wen started the car and did not rush to set off. Instead, he lit a cigarette. Shen Yingjie took out a small mirror and pretended to make up. He observed the few tourists who left one after another through the back viewing mirror, but he did not find anything until the cigarettes burned out.

"No matter how many, it may be an illusion." Xu Wen threw away the cigarette butt, stepped on the accelerator and left the parking lot. He had to pass by Baotou from Urat front flag to Wuchuan, so he decided to rush there overnight.

No abnormality was found along the way, and drove to Baotou in one breath. Xu Wen and the others were extremely tired. They had dinner and rested in the city. They returned the car early the next morning and signed up for a tour group to Wuchuan. The slight change was purely to try out what would happen.

The tour bus slowly drove over, and Xu Wen and Shen Yingjie snatched in front of a group of tourists, and as soon as they got on the bus, they occupied the front seat. The purpose was to talk more with the tour guide, and they also pretended to be careless and very stupid to attract prey.

But after only a few words of conversation, Xu Wen was stunned by the tour guide's expression and answer.

"What is this 'Er Eqi'? I'm a local, right? I've been a tour guide for six years, but I've never heard of it. But in the past two days, three people asked me, you're the third one."

Not only was Xu Wen stunned, but Shen Yingjie was also incredibly surprised. However, after all, they had been engaged in field work for many years and had experienced it. They immediately changed the subject and did not attract the attention of people around them.
