The so-called dream tells you a thousand years of success. In dreams, time is a vague concept.

In a dream, it is always difficult for the dream to understand where the dream begins and how it ends...

The real and real dreams are difficult to determine, and there is no trace when they come.

When Yuan Shichen returned to his mind and returned to the ruins, the night had already left, and the dawn of dawn had gradually spread out.

"Qingchen, Weichen, I haven't seen you when I woke up. Have you been here all night..." Lin Feng's voice came from a distance.

"Well~, I, I just want to see if there are any new clues." Yuan Shichen didn't know how to explain, but he was speechless for a moment.

"Don't work like this. Then, have you noticed anything?" Lin Feng asked in surprise.

Yuan Shichen pondered for a while and said, "It should be considered an important discovery, but my thinking is a bit messy now, so let me sort it out first."

"Okay, go for breakfast. The military rations are great. The canned ham is super delicious..."

The two chatted and laughed, and then returned to the camping site not far away...

In the camp, the soldiers of the army were singing loudly, and Yuan Shichen and others were infected by the atmosphere and started singing along.

After a refreshing "howling", everyone really became energetic.

"Comrades, the plan for the day lies in the morning, let's continue fighting!" Wang Wei shouted slogans in a loud voice.

So, the busy day began like this.

Yuan Shichen sat on a sand dune not far from the ancient pagoda, looking at the pagoda intently, and the dream of last night was staged in his mind over and over again.

Ban Chao, Princess Hanyue, King Loulan..., the dream of the underground stone chamber of Niya Ancient City is obviously related to the dream of last night.

If these two dreams are true, can we find some clues about [Flying Stones from the Sky] from the dream?

"Student Weichen, why are you absent-minded? I didn't have a rest yesterday, but you should pay attention to your health. Otherwise, you should take a break in the morning." Director Zhang asked with concern as he looked at Yuan Weichen standing on the sand.

"Hello, coach Zhang, I have no problem with my physical condition. I was just thinking about some things about [Flying Stones in the Sky]." Yuan Shichen came back to his senses and replied.

"Oh, that's good. Lin Feng and I have been searching for the pagoda, hoping to find clues to locate the square from it." Director Zhang turned around and looked in the direction of the pagoda and said, "It's a pity that the pagoda has been too old. It's hard to find any valuable clues in the remaining part. We have not gained anything since we were busy yesterday."

"Yes, you can locate it according to the approximate coordinates between the pagoda in the dream, the moon and the constellations..." Yuan Shichen seemed to have suddenly grasped the inspiration from the words of Director Zhang.

"Qingchen, are you..." Director Zhang was about to ask, but when he saw Yuan Qinchen thinking attentively, he waited quietly by the side, afraid of disturbing him.

With his amazing memory, the scene of the pagoda in the dream, the bright moon and the starry sky shining together quickly emerged in his mind.

"By the way, I was standing at the entrance of the stairs of the pagoda at the 45° angle to look up at the starry sky. The brightest star in Gemini - Beihe San, and the square was about 500 meters behind. "Because Yuan Shichen had already been familiar with the 88 constellations of the International Astronomical Federation, he quickly made an accurate positioning.

"Guide Zhang, I may have some clues." Yuan Naichen said excitedly, "Although I am not very sure yet, I want to try it."

"That's great. Now any clues are more meaningful than our blind search for a large-scale search." Director Zhang also affirmed with excitement.

"Through my observation last night, I want to try to locate the target square by the coordinates between the pagoda and the constellation. I will argue for the specific method again." Yuan Shichen was not sure whether the dream was real and credible, so he decided not to mention the details of the dream to others for the time being.

"Okay, you go and prepare first." Director Zhang nodded and said.

............

That night, everyone stopped searching and surrounded the pagoda one by one, helping Yuan Shichen find the location of the square through the constellations.

In the night sky, the position of the constellations is not fixed.

Due to the rotation of the earth, the starry sky background rotates around the axis of the sky every day. At the same time, the starry sky also changes slowly with the changes of the seasons, and each year is a period of change.

The zodiac sign was long ago by sailors and travelers as an important sign for identifying directions.

The recognition of constellations is often the recognition of bright stars.

For example, in the northern hemisphere, the North Star in Ursus is the most important basis for determining the direction in the starry sky.

Once the North Star and any other star are identified, the entire starry sky can be identified completely by the relative positions of the stars.

Yuan Shichen soon found the location of Beihe San, the brightest star in the sky.

Through historical records about Ban Chao's Loulan, the impact of the season on the position of the constellation can be determined.

Combined with the description of the wall text and the dialogue in the dream, it can basically be determined that the time for observing the starry sky in the dream is between 11:00 and 12:00 pm.

Based on all the above factors, Yuan Shichen quickly determined the approximate location of the square.

"The square is here, and there may be an error distance of about 50 meters in the east, west, south and north directions." Yuan Shichen made a range judgment based on the position he was standing.

"You guys, immediately surround this area with a cordon and make an identification sign." Corps Wang gave the order.

After discussion, everyone decided to search this area overnight without waiting for dawn.

The scope designated by Yuan Shichen is not large, and the scientific expedition team with more than 20 people can quickly turn it upside down.

Sure enough, in less than 10 minutes of searching, everyone dug many stones for paving under the buried sand.

"Qianchen, you are so awesome. Tell me how you did it, haha." As the location of the square was determined, everyone was amazed.

"If I talk about the clues I got when I dreamed yesterday, do you believe it?" Yuan Shichen was also incredible about such a strange way of discovering it.

"Of course I believe it. I believe whatever you say now." Lu Qinglian said with a smile.

"Come on everyone, [Flying Stones from Away] summon us underground in the square. My big shovel is already hungry and thirsty." At this moment, Lin Feng was full of energy, waving the shovel at all times while shouting slogans.

"Discover, discover, the entrance is here..."
