Soon, the other party agreed to Zhou Xin's request to stay here for a while, and warmly invited Zhou Xin and them to be guests there. Pen "Fun" Pavilion www.biquge.info

For their invitation, it is obviously not possible not to go, but if you go immediately, Zhou Xinxin is not ready. He thought about it for a while, and then set the time of the visit in a few days under the pretext that "the situation of the submarine is very bad right now, and he can't leave for the time being."

After dealing with the other party's series of inquiries, Zhou Xin silently breathed a sigh of relief in his heart, and then he began to ask about them and the situation of this planet.

According to the other party's self-report, Zhou Xin learned that the civilization here called itself "Nuoshan Civilization". The recorded history of civilization even surpasses that of Earth's civilization, reaching a full 10,000 years (a year on this planet is equivalent to 320 days on Earth). In the ensuing long exchanges, from the various clues obtained from the other party's mouth, it was inferred that Zhou Xin believed that although the scientific and technological culture of the Nuoshan civilization developed more slowly than that of the earth, there was no doubt that it had reached or approached the technological level of the earth's civilization in the 22nd century. With such a level of technology, the public could not understand why they had not yet established a normal cosmological theory.

What's even more strange is that although the Norshan civilization did not recognize the planet and the universe, they already knew that the world under their feet was spherical. The voyage around the world was completed hundreds of years ago, and they have even drawn up very accurate maps of the planets. However, in the next few hundred years, their understanding of the whole world came to an abrupt end. Aside from the occasional exploration of the underground, they never thought about what was in the sky. Even after the invention of the flying machine, they did not think of continuing to explore higher ground, and the whole sky seemed to be a forbidden area, and even the bravest people of the Norshan civilization never stepped upwards to explore.

Moreover, in the process of communication, Zhou Xin found that they themselves did not know when the concept of a wall in the sky appeared. As if out of thin air, this idea naturally popped into their minds, and after it appeared, they were convinced of it. No one has ever wondered whether such a thing as a wall in the sky is justified or not, whether it is in line with their previous and current observations. The existence of that wall is as if it were the only truth, and at the same time it is like a shackle that firmly binds everyone's thinking.

Zhou Xin really couldn't understand why this idea was so ingrained in the thinking of the Noshan civilization, and in the following exchanges, he tried to turn the conversation to the planet or the surrounding universe more than once, but they always avoided it. After a period of observation, Zhou Xin found that as long as he asked questions about the economy, politics, culture, and other non-cosmological aspects of their civilization, they were always able to answer them normally. But once asked what they know about the sky or the outside world, they either have only one answer, which is the wall, or they simply ignore the question and jump straight to a completely unrelated topic. Zhou Xin couldn't help but have a trace of doubt about this strange reaction of the Nuoshan civilization, but he could already roughly think of what kind of reaction they would make after he raised doubts to the other party, so he didn't really say it.

In the process of chatting, Zhou Xin also intentionally or unintentionally asked the other party about language and writing. For this problem, they didn't have anything to avoid, but directly told Zhou Xin the reason. To the surprise of everyone in the command module, the reason why they were not familiar with their own language and writing was because the entire Norshan civilization had not used the language for nearly two hundred years.

"How is it possible, if you haven't spoken your own language for nearly two hundred years, how have you communicated during that time?" Zhou Xin asked in surprise.

The other party did not answer this question. Under Zhou Xin's questioning, they only gave an ambiguous answer, "The reason is a bit complicated to explain, so let's wait until we can communicate face-to-face." ”

Since the other party has already said so, Zhou Xin is not very good to continue to ask. So he asked the next question.

After chatting for a while, Zhou Xin suddenly realized a question, "Can we establish a stable communication channel between us?" Such a primitive way of communication is really inconvenient. ”

The other party was silent for a while and then replied, "We have the same idea, but judging from the previous contact, it seems that the communication method we used is not suitable for you, I don't know if you have any way to solve this problem." ”

This is the case, so Zhou Xin did not delve into the reason. He thought for a moment, then replied, "It's too much trouble if we both had to take the time to learn from each other how to communicate." Otherwise, how about we send you a few communicators, and then rely on them to talk to each other, what do you think? ”

In less than a minute, the other party replied, "We don't have any opinions on our side." ”

"Then we'll send the communicator over." Zhou Xin said, and then he added with a smile, "I just hope you don't shoot down our communicator again." ”

"I'm very sorry, but we did go a little too far yesterday, I hope you don't mind."

"Forget it, if I really mind, I won't be in touch with you now." Zhou Xin replied disapprehantly, "Okay, the probe transporting the communicator has already departed from us, and you should be able to see it now, which is the aircraft with the box hanging underneath." In addition to the 10 communicators, there are also instructions written in your script, and the operation method is not difficult, and you should be able to learn it easily. After that, he added, "Then I'll wait here for your contact." ”

After that, everything went very smoothly. In the picture, Zhou Xin saw that the detector carrying the communicator flew smoothly over the open space between the two sides and landed near the signal transmitter......
