Wait, there's still some. I couldn't upload it, so I copied it:
The second revision, the explanation I missed.
Regarding the underground river, I have been thinking about whether the existence of the underground river is true. If, as mentioned above, people in the tunnel have hallucinations and heard underwater sounds, but the fat man didn't hear them, then does the underground river really exist? I thought about it. Personally, I think it exists, but it's not an underground river. It's just that the water source has become smaller, so that the fat man can't hear it, but others have heard it because of illusion. They mistakenly think it's Du Zi's underground river with large water flow, because in their cognition, the underground river in Du Zi has not disappeared, but returned to the ground. Of course, maybe they saw the Du Zi underground river, but after thousands of years, the desert underground river should have dried up a lot, not to mention the crustal changes, so they really found water, but it was not that big.
Why do you say they must have found water? First of all, as Chu Jian said, Khufu asked him and Sadipong to take Ye Yixin, bring water, leave the underground river and come up to find a Li Man. With water? Where did you get the water? It may be the water in the kettle itself, but I prefer to leave the underground river. He filled the kettle with water and returned to the ground, so there should be water. Second, if drawing water is his illusion and there is no water source, will he have no objection to the empty pot with Anliman on it? A Liman has never been to town. He can't be hallucinating. Even if he has no objection, he is still on the ground alone, and the team can't leave him more than one person's water. Even if one is enough for three days, how many days will the team stay underground? Even if he is ready for two days, two days, four people on the ground, each drinking water for two days? And later, when fleeing in the desert, the fat man fell down first, but the weakest Ye Yixin insisted on the camel, without water support before? How is that possible? ...
So, they must have found water underground, and there is nothing wrong with it, otherwise it will not be good until they come back.
There is another place, why do people look for water? Wouldn't it be better not to look? My guess is, because water is the only way to reach the coffin of the konjac queen's body, when is the konjac body the strongest? The closer you get to it, the stronger it becomes, and even let khufu almost commit suicide directly! Why is water the only way out? First, after entering the ancient city, people saw the jade eye. The only key is Yu Pei, the fat man. So, it has never been opened here, but there are several skeletons in the hill-like treasure house. So, obviously, someone has come in before, so they came in from other places. But in the underground river, the dark stone bridge was raised instead of falling. Why? Because the previous people passed through here, but they obviously didn't enter from the entrance of khufu, so my guess is that no matter where they enter, the underground river water source is the only way to the final destination, which is why even under the illusion of konjac control, everyone still found the water source.
Revise for the third time and analyze some problems.
As for the water source, I have explained it above. From the point of view of survival, I prefer to have water. In addition, khufu realized the illusion and asked the fat man if he had any water. The fat man said no, he fell in the desert, and his voice was in a trance. His fantasy was shattered when he saw three students. Why are you in a trance? Because the underground river that Khufu thought of was fake, but the fat man said it was all in a sandstorm. I estimate that one or four people drank all the water while waiting, and the trio and the professor drank all the water in the tomb. Everyone's pot is empty, so the fat man says there is no water. Second, even if there is water, it is still in the student's pot. However, the professors of the three groups can't come back without water. Ye Yixin's body does not support leaving the water, and the sandstorm escapes. Fat people say that without water, water exists, which is not enough to be a doubt and counter-argument. So I insist on the point of small water source.
As for the notebook, the seeker went crazy when he came out. Yang Ping said that this man may be as crazy as the professor, because he saw his companions killing each other, so the notebook was actually taken out. But why did Yang Ping know about it? In the play, it is said that her father bought it to take people to Kunlun and it disappeared. Combined with the ending, then her father is fine, but he left a notebook when he ran away. At the beginning of the book, only Khufu and his comrades have been to Kunlun Glacier, but no one else has. After the play was changed, everyone went together. The notebook is in Kunlun. This time, her father asked her if she wanted it back so that she could enter the ancient city.
Regarding the photo of the fat man, taking a photo is really a point. Because there is no novel, I am thinking of two possibilities. One is that there are no photos, just a fat man's subjective imagination, and the act of taking pictures is just imagination. Second, there are photos, but the camera was brought in by one of the four people, but everyone thought it was taken by a student. In fact, it may have been shot by Khufu, Yang Ping or even a professor. Otherwise, this can't be explained, which is different from what three students said.
