The cave was very dark, only fireflies floated around it, the air was cold, and the humidity was heavy, so it was not a good environment for conversation.

Xu Wen didn't speak for a while, he was thinking about how to speak.

None of this is of this world, and it's easy to explain what they are, but how can he not let his identity be exposed?

The surroundings were very quiet, even Tianqing glanced at him, did not urge him, returned to the ice monument in the center, stared at those two words, as if he had been distracted again.

"I ...... Actually, not the people of this world. ”

After a long time, Xu Wen finally spoke. There was a slight hesitation when he spoke, but his expression became firm as he spoke.

Why hide it?

This is a conclusive fact, he didn't say it to Lian Tianqing today, and he would tell him one day.

Lian Tianqing paused, turned his head, stared at him deeply, and didn't speak, but he didn't seem surprised.

"My original name was Xu Wen, my real age is twenty-five years old, and I am an ordinary clerk, you can understand it as an employee or something. Xu Wen tried his best to explain in words that even Tianqing could understand.

Lian Tianqing nodded, sat down on a stone next to him, and assumed a posture of listening patiently.

His appearance made Xu Wen feel a little relieved, and he let out a sigh, sat down next to him, and finished the sentence.

Then, he found that Lian Tianqing's expression seemed to be slightly strange, and asked a little nervously, "What?"

Unacceptable?

He was hanging his heart when he saw Lian Tianqing looking him up and down, and then said, "Your behavior and conversation don't look like a hired man." ”

"Oh. Xu Wen breathed a sigh of relief and explained, "Our world is not the same as here, you can think of it as thousands of years later, it has advanced a lot in all aspects. When we were born until we were six or seven years old, we had to go to school in a unified school and receive nine years of compulsory education. During this time, students learn the basics of literacy, arithmetic, simple physics and chemistry, and so on. After that, you can continue to study and learn more knowledge if you have a certain ability. I graduated from university and received 16 years of education before I started working. ”

"Anyone can go to school?16 years of education?" Xu Wen couldn't maintain the calm on his face with just a few words, he tilted his head sharply and asked movingly.

"Yes. This has been going on for decades, and by now, almost everyone there is literate, and can do basic calculations. Xu Wen introduced the education system of that world, and Lian Tianqing stared at him tightly, listening very attentively.

"Where did you get all these things?" asked slowly, as his gaze shifted to the ice sculptures.

"Yes and not quite. Xu Wen nodded and shook his head, "Some of them are from our time, and some of them are a little earlier, and they are not non-existent in our place, but they have changed." ”

He got up and walked to the half-left amusement park in Moze, and introduced Lian Tianqing from the steam age.

How the steam engine was invented, and what kind of influence it had, both industrially and spiritually.

The steam engine did not originate domestically, so he went back and gave a little introduction to the world map.

Then came the advent of the electricity age, the booming foreign countries, and the stagnant domestic countries.

Then, there is the world war and being invaded.

These are all the knowledge in the history textbooks at the beginning, and when Xu Wen talks about it now, he finds that one link is one link after another, and the logic of the world is so clear.

Steam, electricity, moon landing, atomic bombs, the Internet, the universe.

Xu Wen actually spoke very briefly, not too deeply, and there were many words in it that even Tianqing had never heard, and it must be difficult for him to understand.

But apart from a few initial questions, he never interrupted again, just listened quietly.

Xu Wen didn't want to talk so much at first, he just wanted to introduce a little bit about his origin and what these ice sculptures were.

But after actually talking about it, he realized that everything has its own cause and effect, and human beings have new discoveries and new inventions, and then these new discoveries and new inventions in turn have deeply affected the course of human beings, and so on, and so on, to the world where he was born and raised.

It was as if everything was predestined and inevitable.

Even if you change the world and change some people, it may affect the direction of some of these historical events, but it will still be generally the same and will not deviate too much.

Finally, he talked about the universe, he talked about space, he talked about quantum physics.

He actually doesn't know much about these, but he has read a few articles and a few popular science books, so he can only try his best to describe them to Lian Tianqing.

Lian Tianqing sat on the stone, raised his head, looking at the dark ceiling, and his eyes seemed to see the infinite starry sky through all these barriers.

He didn't say anything, and Xu Wen didn't know if he understood it, but he didn't care, he just spoke by himself.

Suddenly, a glimmer of realization passed through his heart, and it passed so quickly that he paused and didn't catch it.

"So, even in your time, it is impossible to be free of confusion. In this momentary pause, Lian Tianqing said.

"That's right. The world is so big, how can anyone know everything? Omniscient and omnipotent, that's not man, that's God. Xu asked.

"Hmm. Lian Tianqing replied simply.

"Heaven is not confused...... It probably doesn't mean that you really know everything and don't have doubts, but that you have explored the truth of this world, the world we live in now. Xu asked.

"What is it?" asked Lian Tianqing.

Obviously, he is only a half-step genius, and Xu Wen is still far away, but his posture of questioning is very natural, and there is no mustard between master and apprentice.

"I don't know......" Xu Wen shook his head.

He felt that he was only a thin piece of paper away from the truth, but paper was paper, and one step was also bad, at least until now, he still didn't know what this world was and what it had to do with the other.

"I didn't know anything about carpentry or construction, and I didn't think I would be interested in anything. Then, I somehow inherited a house. Xu Wen turned the topic back to himself and talked about Xu Zhai.

Compared with the real world, Xu Zhai is another kind of wonder, and Lian Tianqing listened very attentively again.

"No wonder. After Xu Wen finished speaking, Lian Tianqing's expression was a little strange, and he suddenly said two words.

"Huh?" This is the first time Xu Wen has told others about this matter, and that person is still Lian Tianqing, which has a special meaning to him. He was waiting for Lian Tianqing's reaction with a little trepidation, when he suddenly heard these two words, he was a little stunned.

"No wonder you're so close to Lin Lin. Sometimes I think you like her, but in the blink of an eye, you cool down again and push her away. Lian Tianqing said lightly.

"Hmm...... Cough cough cough!" Xu Wen didn't expect Lian Tianqing to take everything into his eyes at all, and he said it directly at this moment, but he was suddenly choked and coughed violently.

"And in your own heart, you also think that you don't belong to this world, right?, so what is this world in your eyes?" asked Lian Tianqing.
