Seeing Han Nuo's expression, Liu Yan smiled and handed Han Nuo a book, Han Nuo took the book and saw that it was his own book on dry cement technology.

"Are you trying to find some excuse to prevaricate? Don't say this book isn't yours. Liu Yan opened the cover of the book with a little bit of his hand.

Through the faint moonlight, Han Nuo clearly saw two lines written at the bottom of the preface page of the book: Han Nuo, purchased from Xinhua Bookstore on September 10, 2007.

Han Nuo laughed helplessly, "How did you get this book?" ”

"Old man Liu has been looking for you for a long time, so he has always suspected that you are from another world." Liu Yan's gaze swept over the book, "That square text is quite complicated, and it took three rune masters ten years to fully understand what this writing is." It's a pity, it's not a practice. ”

"It's a building material made in my world." Han Nuo finally decided to confess.

"I know, I've tried refining some, and it solidifies quickly when mixed with water, so it's a good material to replace nephrite."

"Master, don't you blame me?"

Liu Yan shook his head, "I'm just wondering how you came to this world through the void with your mortal body. Not to mention whether you have a spiritual root or not, the power that pierces the void alone can make you die tens of millions of times. ”

"I'm also very strange about this, Master, do you know that there are other worlds outside this world?" Han Nuo was about to put the book into the storage bag, but Liu Yan snatched it back.

"Do you know the word Three Thousand Worlds?" Liu Yan asked Han Nuo.

"Yes." Han Nuo nodded. "A thousand worlds together are called small worlds, a thousand small worlds together are called middle worlds, and a thousand middle worlds together are called great worlds. The Three Thousand Worlds is the collective name of the Great Thousand Worlds, the Middle Thousand Worlds, and the Small Thousand Worlds. ”

"A world like ours is a small world. Those cultivators who have cultivated to the realm of transforming gods will go to the Middle Thousand Worlds through the Ascension Immortal Terrace. After cultivating to Mahayana in the Middle Thousand Worlds, one can soar to become an immortal and enter the Great Thousand Worlds. Liu Yan explained, "So, you ask me if there is any other world outside this world, don't you know this common sense in that world?" ”

"Huh? Is that what you say? I always thought that 3,000 worlds meant a billion small worlds! Han Nuo's eyes widened.

Hearing this, Liu Yan was silent for a moment, looked at Han Nuo, and his eyes turned twice.

Han Nuo could tell from this expression that she didn't know the exact meaning of the Three Thousand Worlds, but she didn't dare to continue asking.

"Skip this question, I haven't been to the outside world as a teacher." Liu Yan played a trick.

"Okay, what else is the master going to ask?"

"Aren't there immortal cultivators in your world?" Liu Yan asked curiously.

Han Nuo shook his head and briefly told her the history of the development of the earth's civilization and the history of the Chinese civilization.

"But in the "Fengshen List" you gave me, there are obviously many scenes of Yuanying monks fighting. The fire dragon dart that injured Huang Feihu and the flower basket that took away the fire dragon dart are all magic weapons! Liu Yan asked a serious question that made Han Nuo speechless.

Although Han Nuo has loved watching the Fengshen List and Journey to the West since he was a child, and even after coming to this world, he has restored most of the plot with the editors, but he has never linked the content in it with immortal cultivators.

"So, could it be that there are really immortals on the earth?" Han Nuo muttered in his heart, and he felt his heart beat faster.

"There's really no way to answer this question." He looked at Liu Yan frankly, "But if I can return to Earth one day, I will definitely figure this issue out." ”

"Okay then." Liu Yan went through the information that Han Nuo said in his heart, and basically confirmed that the information that Han Nuo said was correct. "What about the Han family's firm?"

"What happened to the Han family's firm?"

"That kind of business model is also unique to your world?" Liu Yan asked.

"I don't think it's unique, right? Isn't there a chamber of commerce in this world? Han Nuo scratched his head.

"No, it's different. The Han family firm gives people a very dangerous feeling, and I think it will trigger some irreversible social changes in this world. When Liu Yan said this, Han Nuo was in a trance.

"Master, you're amazing. Irreversible social change, that's what we write in our political books. Han Nuo clapped his hands.

"Well, is there one?" Liu Yan had a look of embarrassment after being praised. "What do you call this in that world?"

"It's called social change, it's capitalism that replaces feudalism, and the Han family business name you said is dangerous, probably because you see the germ of capitalism." Han Nuo excitedly popularized the concepts of feudalism and capitalism to Liu Yan.

Liu Yan pursed his lips and thought about it, and asked a key question: "What are the conditions for entering capitalism from feudalism?" ”

"Workforce Development." Han Nuo replied without even thinking about it.

"Speak human words."

"The progress of labor production technology!" Han Nuo said seriously.

"Is it those Sky Piercing Drills, Earth Splitters and the like that you studied?"

Han Nuo nodded.

"Okay, I see, if you go back, you will let people ban all of this." Liu Yan nodded earnestly.

"Huh? Why? ”

"Because from your explanation, the reason why mortals study science and technology is because of the advancement of labor production technology, and more people can come out of the land. To stop this so-called germination is to eliminate these new technologies. ”

"But Master, as you just said, this is irreversible. Once people know it's okay to do this, they won't want to be like that all the time. ”

"Then let all those who know be wiped out along with these technologies." Liu Yan said a conclusion that made Han Nuo's hair stand on end.

Han Nuo was stunned and didn't know how to answer. This woman actually has the courage of the first emperor, could it be that the world is going to have a tragedy of burning books and pit Confucianism because of herself?

Liu Yan looked at Han Nuo, "That's it, you go and rest for a while." Come up to me early tomorrow morning, and I'll tell you about the exercises. Liu Yan pointed to the top floor of the Han family's business, and then floated away.

Han Nuo was stunned on the tree for a long time, and he began to realize that his arrival might have really caused some impact on this world.

Although he didn't do those things himself, if he told others about those ideas, the world would really be different.

The Han family business is really a spark.

Han Nuo sat on the tree until dawn, in fact, Liu Yan didn't need to rest, and he didn't need to rest.

But perhaps the amount of information exchanged just now was too large, so that Liu Yan and he needed a little time to digest it.

Why does the Immortal Cultivation Realm not allow mortals to gain power?

Immortal cultivators can rely on thousands of years of cultivation to obtain the power to move mountains and reclaim the sea, but mortals can't even have the technology to blow an air conditioner?

Obviously, the technology of mortals is very easy to realize, and it only took a few hundred years for the earth civilization to complete the leap in science and technology from the small magnetic needle of Oster to the chip technology.

However, the civilization of immortal cultivators requires countless people to go through layers of screening one after another, and finally come up with so many peerless geniuses to ascend.

If a technology cannot benefit all the people of the world, then what is the meaning of its existence?

Just when Han Nuo fell into this kind of divergent thinking and couldn't extricate himself, a pleasant voice sounded in his ears.

"Brother Han hasn't closed his eyes all night?" The person who came was Jin Yu, who sat where Liu Yan had sat before, looking at Han Nuo in a daze.

Han Nuo looked at this woman, at this time, the morning sun was beginning to appear, and the glow was all over the sky, casting a yellowish glow on Jin Yu's body.

"The girl didn't sleep all night, didn't she?"

Jin Yu nodded, "Your master should have already told you what my identity is." ”

"It doesn't matter." Han Nuo smiled and said, "I guess you have long confirmed that I am not your father-killing enemy, I understand what you are doing, people have no choice if they don't have strength." ”

"But I could have chosen not to tell them about your trip to the Kingdom of Wuqi."

"They can all find the country of Yimo, presumably the Han family already has their people, right?"

"Then why are you so comfortable and bold to stay here?"

"I have already said that those who do not have the strength have no choice. The reason I'm here is because I'm forced to stay here. After escaping from the sect, everywhere I went, it was just a choice that I was forced to make. ”

Han Nuo smiled, "If there is a choice, will you be a heroic warrior?" If you were strong enough, would you pour wine for your father's killer? ”

Hearing Han Nuo say this, Jin Yu smiled, "Kill your father's enemy? I really didn't regard Senior Liu as an enemy who killed my father, and for some reason, I couldn't hate her. ”

"Oh? Why? ”

"Her gestures and smiles make me want to be like her." Jin Yu looked at the sky.

"But she killed your father."

"Yes, father, the father who gave birth to me and raised me, sent me to another sect to be the father of the heroic warrior." Jin Yu's face showed an extremely painful expression.

"Maybe he didn't have a choice......" Han Nuo looked at Jin Yu, not knowing how to comfort her emotions.

"My mother was discovered as a heroic warrior in another sect, and finally she was drained from her soul to refine her gods, and she was not even allowed to enter reincarnation. He didn't have a choice? You told me the story of Luo Jun's father and daughter, so a mortal ......" Jin Yu tried his best to control his emotions and didn't say any more.

"It's dawn, Shizun asked me to go to her early in the morning, you can calm down here first." Han Nuo didn't want to watch this woman explode around him, because he really didn't know how to comfort the woman. So I made a very casual excuse and ran away.

Watching Han Nuo leave, Jin Yu's emotions that had exploded to the extreme suddenly retracted, smiling at the corners of his mouth, but tears flowed from the corners of his eyes.

"How long are you going to watch?" Jin Yu asked somewhere under the tree.

I saw that a ghost woman with a snake head and a snake body appeared out of thin air, and it was Yu Yun's daughter.

Yu Yun slid up around the trunk like a snake and wrapped itself around a branch next to Jin Yu. "Brother Han is a nerd, but he is indeed a good person."

"Oh? Are you interested in him? ”

"Impossible." Yu Yun shook her head, "I don't have the courage to force myself to cultivate to the God Transformation Realm for a man, besides, I don't think people with two eyes are good-looking." ”

"And what is the reason you are pestering him?" Jin Yu was less wary of Yu Yun by half.

"Because I want to travel and be safe with him."

"His strength is so weak, and he has provoked the second great immortal cultivator sect in the Central Plains, where is it safe?"

"None of us can avoid external dangers, what I'm saying is that he is safe and will not pose a threat to me." Yu Yun said with a smile.

"Even if he wants to threaten you, I'm afraid he doesn't have that condition, right?" Jin Yu looked at Yu Yun's snake body and laughed.

"Oh? Then you have to be careful, you meet the conditions. Yu Yun teased.

"Like you said, he's a nerd." Jin Yu's smile looked much more relaxed.

"The knot is over, why don't you walk around with me today?" Seeing Jin Yu's expression, Yu Yun had a hint of tenderness on her face, "You will be bored anyway, Brother Han should have been staying with Senior Liu all day." ”

"You're always doing this kind of idleness." Jin Yu's eyes stared into the distance and said lightly.
