The wind and snow outside the tents seemed to be getting stronger, and the raging wind crashed against the small tent that stood alone in a corner of the square.

Qijian's words were like a thunderbolt from the sky, which made Zhu Beichen's already dead heart thump, and he excitedly confirmed: "What, you tell me again." ”

The sound of wind and snow mixed together was a little messy, covering up the vague words of Qijian, Zhu Beichen almost thought that he had heard it wrong, and he suddenly became emotional.

I'm afraid that the rest of the food won't be able to support them out of this land, and now the sudden turn of events has made him a little uncomfortable.

Qijian still smiled angrily as usual, I really don't know if there have been other Taoist priests who have been so elegant since ancient times, at least in Zhu Beichen's memory, the obscene Taoist priest is definitely not like this.

"It's snowing outside." Qijian was not in a hurry to explain, but slowly guided Zhu Beichen's train of thought like a riddle, this approach provoked Zhu Beichen to be really dissatisfied, what kind of dumb riddle to play, who didn't know that it was snowing outside.

"Then, can you finish the words at once, when will you be like a fat man, learn to be flamboyant." The tent was very crowded, and Zhu Beichen was so anxious that sweat was hanging on his forehead, tense his nerves in anticipation of Qijian's next words.

The wind and snow became worse, and the strong wind blew open the door of the tent, adding a little chill to the tent.

"It's April, don't be too surprised by the idea we just came up with." Snowfall in April is extremely rare, and it is only in a few years that cold air moves southwards that leads to a sudden snowfall in April and May.

However, the presence of this weather phenomenon in the area of the ancient city is a strange phenomenon. First of all, the question of where the cold air comes from is the question of where it comes from, and the temperature is constant at a given temperature value all the way, giving them the illusion that the weather does not change here.

However, the sudden appearance of snow in front of me broke this suspicion, and it seemed that this sky had become an atmospheric system of its own, and even there was an atmospheric circulation.

"When you first came here, did you all feel like this, the sun above us, and the layers of clouds, although they all looked like real things? Have you not suspected that all of this is false? The sun, the clouds, the moon, the starry sky, everything is illusory, and the cyclic changes of the climate at the four seasons are all artificially formed according to a certain law, and they have been running in this orderly manner for thousands of years. Between the seven words, he took the kettle and poured a few mouthfuls of water, looking at Zhu Beichen's gradually changing complexion. This conjecture is not without reason, at least this group of people had the same premonition when they first arrived, and they were deeply impressed by the warm sunshine and high oxygen content of the air here.

"Fake?" The assumption of the Seven Rooms is too terrifying, is it that the sunshine overhead, the entire beautiful starry sky, are all illusory, or are they celestial bodies built by the ancients who lived here?

"How could it be fake. The temperature of the daytime is obviously the real sun. "The ancients who were able to create the sun, the development of civilization and technology will be amazing. But if you think about it, the white light from the clouds is indeed a little unnatural, and can the celestial bodies created by relying on technology really completely replace the role of the real sun and moon? No, there must be a difference.

They have been ignoring the factor of sunlight, especially after studying Su Hao's diary all night before they came to the conclusion that the sun overhead was problematic, and the light appeared extremely unnatural.

Su Hao's diary records the change of the incident angle of light in the sky of the ancient city at around 2 pm to 3 pm on June 15, and the diary that turns the page forward records strange celestial phenomena. It almost reminded the seven rooms of decades ago on the same identical night, Su Hao's expedition team camped in the corner of the square, that night of heavy snowfall, the scene that Su Hao experienced is not what they are experiencing now.

Qijian said: "You take a look at this diary first, I checked Su Hao's diary before, and there was not a single word snow mentioned in all the records before June 15. This undoubtedly proves our suspicion that the celestial phenomena here are fixed, and the temperature will be stable within a set value all year round. If all the celestial objects above our heads are real, how can we explain that there will be no normal weather changes here? ”

July picked up Su Hao's diary placed in front of the folding table, and the one in front of him was the night before June 15th, and the time and scale of the blizzard were exactly the same as the heavy snowfall tonight. But this is not enough to say that the next day is the day when the ancient city opens, and the same blizzard day is really only one night, and the date recorded above should be on June 14, and the time is not the same at all.

"But the time is not right at all, Su Hao's diary records June, and we are only in early April now." July's gaze wandered between Zhu Beichen and Qijian, and fell suspiciously towards Qijian.

In fact, the discovery of this situation also relied on the careful Wu Min, who brought a illuminance meter with him in the equipment configured before entering Lop Nur. The illuminance meter is a special equipment used to measure the light intensity level, and the sensitive germanium photocell is used as a probe, which makes the battery produce current of different intensities according to the different light intensity, and then directly converts the current signal into a digital signal of light intensity through the digital-to-analog conversion circuit.

"Remember the dead Wu Min?"

Wu Min, who died when he parachuted down last night, how could he forget it so quickly, July nodded: "Remember." ”

"When I was sorting out my backpack, I found this miniature illuminance meter in the backpack I was carrying, which recorded the change in the intensity of sunlight every day after they entered here, and the values recorded were constant for several days. If it is normal, the light emitted by a real celestial body will not change at all. The only explanation is that everything in heaven is fake. "It is like an artificial celestial body that operates according to a predetermined program, and the stable operation of the program controls the constant emission of light and heat by the laws of the celestial body. However, since this morning, the values recorded by the illuminance meter have completely changed drastically, and the values on the illuminance meter have risen sharply in the middle of the day, and after comparing with the previous days, it seems that this artificial celestial body is changing. Towards evening, the intensity of the sunshine dropped more than on any other day, and then a snowstorm fell in the heart of the mountains at night.

As the seven rooms solved the mystery step by step, the tent was silent, only the wind outside that weakened a little bit swept the tent's curtains. Zhu Beichen shivered without warning, recalling all the things he had experienced on the road, the mountains and jungles and the plants in the swamp forest, they all presented a vibrant scene, the perennial stable sunshine time and sunshine intensity made the growth and reproduction of plants all year round, and the time of every day and night was almost the same length, and when he noticed this phenomenon, he believed the speculation of Qijian.

The clear blue sky here, the empty and pleasant stars at night, all of this is fake.

Zhu Beichen's voice also became ethereal, whether the ancient city was also like the celestial bodies here was not real, "Okay, I agree with your statement on this." But even if you find out that there is a problem with the celestial body, what will it help us to open the entrance to the ancient city, Su Hao entered the ancient city in June, and our current supplies are simply not enough to support us until that time. ”

In the end, Zhu Beichen's voice almost roared, what is the point of solving the mystery, after all, it still stops here, only one step away from the ancient city, but it is close to the end of the world.

Scattered snowflakes splashed on Qi Ruoshui's face, she put her arm on Zhu Beichen's violently shaking shoulders, and said softly: "If this inference is true, the conclusions we have drawn from the computer simulation during the day cannot be counted." ”

The data model deduced in Jiang Erye's computer uses the lighting angle formed by the trajectory of real celestial bodies on the earth to simulate the opening time of the entrance to the ancient city, since everything here does not follow this law, the date of deduction is naturally wrong.

The fat man's reaction was undoubtedly the quickest of the bunch, and he said, "Great. I knew that I wouldn't be suffocated by urine, fat man. ”

After listening to Qiyue's calm analysis, Zhu Beichen's mood eased a lot. There was a hint of admiration in the eyes of Shichima who looked at July, and it was not an exaggeration to use the words of calmness, composure, wisdom and other praises on this wonderful woman.

Qijian patted Zhu Beichen on the shoulder and smiled mysteriously: "We are rewriting a set of programs to summarize the data recorded by the illuminance meter into the computer, and re-analyze the problem of the angle of light incidence, I believe that one of the matching dates must be June 15, but it will not be only that point in time." ”

Su Hao's diary has undoubtedly accurately pointed out that the entrance to the ancient city will inevitably open on June 15, and the strange natural scene the night before the entrance opens is also a precursor. Now Han Qingxin is operating nervously in front of the computer, and it is a little difficult for an old man like Jiang Erye to write a set of programs. They tensed their nerves and stared at Han Qingxin, who was racing against time in front of the screen, as if the last glimmer of hope was in her hands.

Time flowed slowly, minute by minute, and the sound of Han Qingxin tapping the keyboard crackled in everyone's hearts, completely covering up the sudden wind and snow outside the tent.

The last knock fell, Han Qingxin's pupils shrank suddenly, stared at the computer screen and said with relief: "It's done, the result will be available in about a minute." ”

The people on the side couldn't bear it anymore, and the fat man pushed aside the people in front of him, rushed to the screen and asked anxiously, "How is it, crazy girl, will the weather be good tomorrow?" ”

How snowy is it turning sunny? Han Qingxin hated this title the most, especially from the mouth of the fat man who annoyed him, and his expression instantly became unfriendly: "What did you say? ”
