About a few minutes after Zhao Lan sent that message to Li Yunfan, Li Yunfan's reply finally arrived: "You can tell other people about these things, but you have to promise me one condition." ”

"On what terms?" Zhao Lan immediately asked.

"You have to find your own explanation for the source of this information, you can't say that the information was obtained from my base, you have to say that you got it yourself." Li Yunfan said with a smile, "You must not involve my base, otherwise, it may affect my base." ”

"Say yes...... Did I find it myself? Zhao Lan muttered, "But this is the result of the labor of an entire team of scientists in your base, I ...... Just keep it for yourself? ”

"Or else?" Li Yunfan said, "Could it be that in the relationship above the surface, you want to be involved with such an underground force?" Or exposing the existence of my base, causing the government to launch a siege of my base? ”

Zhao Lan thought for a moment, and then said, "Okay, I'll find an explanation for these information sources myself." I plan to personally go to the point of one of the calculated Lobachevsky spaces to measure it in the field and verify the authenticity of this information. If this information is indeed true, I will only release it to others. ”

"Whatever you want." Li Yunfan replied, "It is most appropriate to solve this problem with the help of government agencies. I hope you will always remember your promise. I am releasing this information to you to help you understand the truth of this crisis, and I can even use my wisdom to help you and human civilization solve this crisis, but you must remember that you must find a way to help me escape this universe and return to our universe. It's so boring here, there's nothing here, I'm going crazy here. ”

"Of course I remember my promise." Zhao Lan replied, "But...... I think there's a better person to do it for me. You can only send messages at this frequency in that universe, and this information can only be received by me, so it might as well be like this. How often do I publish information and passwords to Rodriguez? This way, you'll be able to keep in touch with your men, who are a little more capable than I am. ”

"No need." Li Yunfan's words still had a smile in them: "Zhao Lan." Do you really trust me to help you wholeheartedly? And...... Do you really trust me to have no other intrigues or plans in this operation? No, you have no way of knowing for sure, and in this case, placing the key interface between me and the outside world on you will help you form a certain deterrent to me. I think that will make you trust me a little more. ”

Zhao Lan patted his head: "But Li Yunfan, do you want to know, does it mean anything to you whether I trust you or not?" If you could communicate directly with your men...... What does it matter if I trust you or not? ”

This matter is the most doubtful place in Zhao Lan's heart. Zhao Lan had already taken the initiative to hand over Li Yunfa's "handle", but Li Yunfan refused on the grounds that he could make Zhao Lan trust himself more. Zhao Lan doesn't think that there is anything important about herself in the face of Li Yunfan, so why does Li Yunfan attach so much importance to his feelings?

"You don't need to pay attention to this now, you'll know later." Li Yunfan said a little secretively, "If there is nothing to do...... You should verify the authenticity of this information as soon as possible. Signs of crisis have appeared, and time may be running out for us. ”

"Okay." Zhao Lan thought for a while, and finally agreed. Then he cut off communication with Li Yunfan.

Zhao Lan needed to purchase some special measuring instruments, and then drive his new Sylvia spacecraft to the survey site to personally measure it to verify the authenticity of this information.

Pi can be measured by pure mathematical calculations rather than field measurements. If one wants, one can calculate the number of 100 billion decimal places of pi by mathematical calculations, and under such precision, it is undoubtedly impossible to achieve such accuracy through field measurements.

But this time the task was different. Whether in Euclidean space or Lobachevsky space, some of the most basic mathematical processes do not change. If you calculate pi by calculation, it will be a number in Euclidean space, and it will still be this number in Lobachevsky space, so there is no point in doing that. Therefore, Zhao Lan must use the method of field measurement.

It's hard to get a measuring tool with such a high level of accuracy, but as a scientist. In this circle, Zhao Lan still has some methods. So Zhao Lan contacted several friends who were on the earth and put forward his own request. It takes a certain amount of time to obtain the measuring tools, so Zhao Lan decided to take advantage of this free time to take a stroll around Hope City. It's been too long to be away from Earth. Zhao Lan felt that she was already a little out of touch with society.

Walking among the tall buildings at will, watching the bustling flow of people, and looking at the various shops one after another, Zhao Lan's thoughts slowly calmed down unconsciously. Zhao Lan casually walked into a building, and then planned to take the elevator to the shopping mall on the thirty-fifth floor.

The elevator door opened, and Zhao Lan saw that there were already several people in the elevator. One of these men was a young woman who stood out. She wore a well-tailored dress. He has long shawl hair and a pair of black glasses with an exposed edge on top of his delicate face. This woman was very beautiful, so beautiful that it was a bit of a handicraft.

Although Zhao Lan is also a woman, she can't help but take a few more glances at this beautiful and somewhat excessive woman. Sensing Zhao Lan's gaze, the woman smiled very kindly at Zhao Lan, so Zhao Lan also nodded and smiled back.

The elevator rose gently, and when it reached about twenty floors, the woman came to the elevator door from the elevator and stood beside Zhao Lan. After another moment, the elevator stopped, and the woman walked out. When she walked out, she seemed to accidentally bump into Zhao Lan, so after stepping out of the elevator door, the woman turned around again and showed an apologetic smile at Zhao Lan. Zhao Lan also responded with a smile, indicating that it didn't matter.

The elevator doors close, and the ascent continues. This matter was just a trivial matter, and Zhao Lan did not keep this trivial matter in mind except for leaving a beautiful impression in his mind.

The elevator continued to go up intermittently, and slowly, all the people in the elevator walked out, leaving only Zhao Lan alone. And this time the elevator operation process seemed to be a little slower, and when Zhao Lan almost thought that the elevator was out of order, the number above the elevator finally jumped to thirty-five, so the elevator door opened, and Zhao Lan also walked out.

A corridor appeared in front of Zhao Lan, and on either side of the corridor were two doors, one door closed and the other open. This seems to be a little different from the expected mall. Zhao Lan's first reaction was that he had made a mistake, but after looking back at the floor sign and confirming that this was the thirty-fifth floor, Zhao Lan had some doubts in his heart.

With the development of science and technology, the building is getting higher and higher, some buildings will divide different floors into different uses, and it is not uncommon for commercial and residential areas to be in the same building.

"Maybe the sign is wrong, the mall isn't on the 35th floor." Thinking like this, Zhao Lan planned to return to the elevator and return to the first floor. But at this moment, the cry of a child suddenly came from the open door. The cry was very poignant, not like the usual cry when you are hungry or unwell.

Zhao Lan's heart moved slightly, and his steps hesitated slightly, but finally walked towards the elevator. It's someone else's child, even if you cry, someone else will take care of it, and it's not appropriate for you to go to someone else's house abruptly in this situation.

As he waited for the elevator to arrive, the child's crying continued and became more and more poignant, as if the baby had really fallen into some dangerous situation. And Zhao Lan didn't hear the expected voice of the father or mother coming to take care of the baby.

Zhao Lan hesitated a little in his heart, so he walked to the door and shouted inside, "Hello, may I ask anyone?" Your child is crying all the time and it seems that something bad has happened to him......"

Zhao Lan shouted a few words, but did not hear an answer. The baby's cries had become more rapid, and there was an intermittent sound that seemed to be out of breath in the midst of the crying. This is very dangerous, Zhao Lan knows, this may be a symptom of suffocation. For a baby, choking is undoubtedly dangerous.

So Zhao Lan couldn't bear it anymore and finally walked into this residential house. Walking over to the voice, Zhao Lan didn't find any crying baby, but only saw it...... A sound system. Even if Zhao Lan had come here at the moment, its sound did not stop. Obviously, this is where the baby's cry came from.

Zhao Lan's heart was relieved, and at the same time, he felt a little speechless. After all, this is someone else's home, and it is not convenient for me to stay here. So Zhao Lan walked towards the door. But as soon as he walked out of the door, a majestic voice sounded: "I am a policeman, I announce that you have been arrested." (To be continued.) )
