"Don't panic, we may still have hope." Professor Wu said.

"Old Wu, you are also optimistic, and now we are completely lost." The fat bear threw the compass that had already broken in his hand to the ground.

"Do you remember that Urati said that he once went to the city of Luoli?" Professor Wu continued.

"But that old guy met by mistake, and besides, he's not here now." The fat bear shook his head.

"Think about what he met before he left the city?" Professor Wu said again.

"Yes...... It's a sandstorm. I replied tentatively.

"Yes, maybe the sandstorm wasn't accidental." Professor Wu lifted his glasses and looked into the distance.

"According to what you say, do we have to pray for a sandstorm? Isn't this a fucking shit? The fat bear frowned and said unhappily.

"I don't think it's necessarily about sandstorms, it's about the consequences of sandstorms." I said intuitively.

"The consequences?" Zheng Tian wondered.

"Yes, the arrival of the sandstorm has darkened the entire sky, and it was in the dark that Urati saw Luo Licheng in the dark." I spoke as I remembered what Urati had told us earlier.

"A city that only appears in the dark?" Zheng Tian muttered in disbelief.

"This is also Xuanxuan, right? Why does something that doesn't exist during the day suddenly pop up at night? The fat bear still didn't seem convinced.

"It's just my inference at the moment, and I don't know what the facts are." I shrugged my shoulders, meaning believe it or not.

Professor Wu smiled slightly: "From a scientific point of view, this is not possible. Then he added: "But this area is not science." ”

"Professor, are we going to wait until evening now?" John asked.

"Now we don't even have camels, we can't go far, so we can only wait for the evening to see." Professor Wu looked at me and said.

The wait is always long, it's two o'clock in the afternoon, and the desert usually doesn't get dark until about nine o'clock, so we still have to wait for more than seven hours, and in these more than seven hours, we have to solve a new problem, the water is insufficient.

We didn't see any fresh water along the way, and the only body of water we saw was the stinging lake underground.

The lack of water in the desert is simply a precursor to the coming of death.

"Why don't we take advantage of the waiting time to find a water source nearby?" Fat Bear suggested.

"Nope." Professor Wu shook his head: "We are in the current environment, and we don't have a guide, so we go out to find water on our own, and we may not even have a chance to come back." ”

"That can't be wasted here!" Fat Bear said anxiously.

Professor Wu looked up at the scorching sun in the sky: "Don't waste it, we make our own water." ”

"Yikes! Lao Wu, you don't want to drink your own boo, do you, do we still have lesbians here? Fat Bear pouted.

Professor Wu shook his head with disdain: "Have you ever heard of the solar distillation method?" ”

"It sounds like a 6 name, what are you going to do?" The fat bear asked, wide-eyed.

Professor Wu did not answer immediately, but wandered around the neighborhood, found a slightly damp ground, beckoned Morson and Black Axe, and dug a pit about 90 centimeters wide and 45 centimeters deep.

Then they stretched out a white transparent plastic tablecloth, fixed the four corners of the cloth, and placed it in the center of the bottom of the pit. A plastic film stretched into an arc is hung on the pit face.

"Light energy raises the temperature of the moist soil and air in the pit, and evaporation produces water vapor, which condenses into water droplets when in contact with the plastic film, and slides into the vessel." After setting up the device, Professor Wu pointed to the sun overhead.

"As a professor, knowledge changes fate!" Zheng Tian gave a thumbs up and said.

I'm really ashamed of myself in this regard, and after getting along with each other these days, I feel that Professor Wu really knows everything, and he has a wide range of knowledge, which is really amazing.

"By the time we get out of the city, we should be able to collect enough water to get back."

"But there are so many of us, can the sun steam out little by little?" The fat bear is still a little worried.

"I'm afraid when we come out, there won't be so many people." The bald Mowson suddenly smiled wickedly, which made me feel very uncomfortable.

"Then you'd better expect your life to be harder." Zheng Tian gave him a disdainful glance and said.

The chat broke up unhappily, and during the waiting, everyone sat on the ground, recuperating and looking forward to the arrival of night.

In the meantime, I glanced at Elanlin, who had been silent for a long time, and found that she had been staring at the silver cross in her hand, her eyes were empty and her expression was stunned, perhaps recalling a moment from the past, or maybe she was not thinking about anything. The light shone obliquely on the surface of the cross, and the mottled halo outlined the silver texture, and a tear seemed to fall in a trance, but it turned into nothingness in an instant.

And Nangong Han still has no signs of waking up, but fortunately, his physical strength is strong enough, so his pulse and breathing are quite stable.

The road ahead is dangerous, I really don't know what the point of being here is? Save the world? No kidding, the world may not even know you exist. Originally, I could have guarded my own antique shop and enjoyed a dull life, but a series of recent events have made me lose this simple right, at this time I think of Uncle Dao, and I don't know what the situation of this old boy is now, anyway, my current situation is very bad, and what I am looking forward to most now is to be able to go back safely. The outlaws of the Odan Group have never been seen since.

As it got darker and the temperature became more approachable, I checked the water collection device that Professor Wu had set up, and was surprised to find that it was already full of water, so I immediately called Professor Wu and gave him a thumbs up: "Professor, you are so amazing, you can get full of water in such a short time." ”

When Professor Wu saw the vision, not only was he not happy, but he showed a strange expression: "Why...... Will there be so much water? ”

"Hey, you are also hypocritical to say that Lao Wu, at this juncture, there is still a lot of water." Fat Bear shook his head and said.

Professor Wu frowned: "Of course I'm not saying that the water is bad, but in such a short period of time, it is impossible to collect so much water, the distillation method is to evaporate the water droplets little by little, we have only been a few hours, and under normal circumstances, we can only collect one-tenth of what it is now." ”

"Whatever happens, this water must be real water, right? If you don't worry, I'll taste it first. After that, the fat bear scooped a pot of water with his own kettle, and drank it, and after drinking, he wiped the corners of his mouth with satisfaction: "This water is not only fine, but also sweet and delicious!" ”

"Maybe it's really me thinking too much." Professor Wu looked at the clear water source in the water collector and said, "Let's fill our kettles with this distilled water first." ”

The dry food we carry should be enough, and now that the water source is sufficient, the worries about supply have been solved, and the next question is whether we can wait until the city appears.
