The old man smiled and said, "Since the little brother is my savior, then I won't hide it from you." I'm researching a time machine, and once it's developed, we can travel to the future, and then we can travel back to sixty years ago, stop this world-destroying monster, and the world will be able to return to its former state. ”

"I don't think there's anything wrong with this world. I heard that although the society in the past was more prosperous than it is now, everyone's life was very stressful. In addition, when you go to school and enter the society, you have to think about how to earn money and how to support your family. Young people don't dare to get sick, and the old people are constantly suffering from all kinds of diseases, and when they get sick, how many years of savings are put in the hospital, why should such a society go back?"

Chu Yihan traveled from south to north, he has also traveled to several cities in the past few years, every time he goes to a city, he will ask some elderly people what it was like sixty years ago, and many old people have a deep impression of the situation at that time. This is also an impression of the society at that time that Chu Yihan summed up through the information he heard.

"Young man, you are right, the society at that time was indeed as you said. But fortunately, the whole society is stable and prosperous, and you don't have to live as trembling as you do now, you don't know when the demon beasts will attack the city. And in the current society, the industrial base is already very weak, and many weapons have been scrapped, even if the rise of the Guigu faction can have a certain lethality to the demon beasts, but that is also limited. And after years of research, the fertility rate of human beings is getting lower and lower now. This proves that the genes of human beings are also slowly changing, and if this continues, sooner or later, human beings will perish. Even if humans don't destroy themselves, they will be destroyed by monsters. The reproduction rate of demon beasts is too fast, and millions of demon beasts are born on this earth every day. Many monsters grow up much faster than humans, and it only takes a few years for monsters to grow to adulthood, while humans need more than ten years. In terms of time and speed, it can't compare to the monster beast at all. That's why I decided to study a time machine, hoping to go back in time and save the world. As the old man spoke, he was also emotional.

Chu Han listened to the old man's words and felt that what he said was very reasonable, if once the human race shrank, the demon beasts in this world were rampant, then the human race would perish sooner or later. He didn't want to see such a thing happen, Chu Han admired the old man very much through what he said. "I haven't asked the old man what to call him." ”

The old man affirmed Chu Han's words and deeds, as well as the ability he showed, "Everyone else calls me Lao Wang, you call me Lao Wang, this is my granddaughter." ”

"Old Wang Ba, hehe, hehe!" Chu Yihan couldn't help but burst out laughing, his smile made the girl next to him unhappy, and stared at him fiercely.

Chu Yihan noticed the girl's eyes, immediately stopped smiling, and quickly apologized and said, "I'm sorry, I'm sorry, I didn't mean to." ”

Professor Wang smiled and said, "It's okay, I never care about these fictitious things, I don't know what you guys call them?"

Chu Han bowed and replied: "In Xia Chu Han, this is Chu Yihan, this is Yu Yan, we are from Kyoto, and we are about to go to Chang'an City, we will send you back by the way, how about it?"

Hearing Chu Han's name, Lao Wang and his granddaughter looked surprised, "You are the little hero of Chu Han who saved Kyoto City! Sure enough, the hero is a young man, that's good, with you to accompany you, it will save a lot of trouble, anyway, we can't be in a hurry to find things, let's go back first." ”

Professor Wang looked at Chu Han's words and deeds as he walked, which were different from modern people, and immediately questioned Chu Han's identity and asked, "I think Chu Han's little brother's words and deeds are very old-fashioned." ”

Chu Han smiled, "Hehe, maybe it's because of my family background." Our family is a scholarly family, and the door style is rigorous, so it is inevitable that there is some ancient style between talking and talking, and I ask Professor Wang not to mind. ”

Lao Wang smiled, "Hehe, where is it, I think you are different, different from ordinary people, otherwise even demon beasts can submit to you." ”

Chu Han didn't answer Professor Wang's words, but instead diverted the topic and discussed with him about the time machine, and several people talked and laughed while walking.

Chu Yihan followed Professor Wang's granddaughter along the way, leaned over to her, and asked long and short questions, "Hey, girl, beauty, what's your name?"

"Guess!" Professor Wang's granddaughter said playfully.

Chu Yihan replied casually: "I see that you are wearing a purple dress, so I will call you Ziyi, okay?"

Ziyi looked at Chu Yihan in surprise, "How do you know my name?"

Chu Yihan was even more surprised, "It turns out that your name is Ziyi, it seems that we are really destined." ”

Chu Yihan leaned into the purple clothes for a while, and then ran to Chu Han and asked, "Brother Chu, what is the name of your demon beast?" Why don't you let me ride it, do you think it?"

Hearing Chu Yihan say this, the demon beast turned its head and roared at Chu Yihan, causing everyone to laugh.
