Chapter 3090: Earth visitor

Chen Tuan seems to be really old. Although he woke up from a deep sleep, and this time he slept for fifty years, even less than he slept on the earth, but if it were before, it wouldn’t be the case at this time. He looked a little sluggish, after listening to Li Yifei, he remained silent for a long time.
Li Yifei seemed a little nervous and excited. If the man in front of him is really the ancestor of Chen Tuan, he would be a legend in both worlds, especially on earth. He has witnessed the changes and changes in that world. The reason Li Yifei also knew, and Chen Tuan was one of the promoters at the time, but he was trapped in this hill at this time? Why is this, and Chen Tuan's ancestor should also belong to the category with the highest cultivation level in this world. It stands to reason that he should not be so depressed.
So what is the reason?
Chen Tuan was silent for a long time, as if something was brewing and thinking. The surrounding raccoons maintained a pious posture, and made some shouts, as if they were chanting.
"Hey!" With a long sigh, Chen Tuan came back to his senses again, his old face lifted slightly, and he glanced at the top of his head. Li Yifei followed his gaze and found that there was something mysterious above his head, like a starry sky, following the raccoons. Chanting, there seemed to be countless floating dust in the air, shining with light, those light floating upward, dotted with the starry sky!
This is a star map. Li Yifei confirmed it. With his eyes wide open, he quickly saw a few familiar places in the sky full of stars. Apart from anything else, the Big Dipper was the most obvious seven stars.
"Is the earth's starry sky?" Li Yifei asked.
"Oh, your name is Earth?"
"Because it's a ball!" Li Yifei replied subconsciously, thinking that Chen Tuan didn't know that the earth was a ball at that time. Hey, that's not right. With his cultivation, I'm afraid it's easy to know that the earth is spherical.
This seems to be a paradox. Li Yifei hesitated and heard Chen Tuan say: "Yes, the earth under our feet is spherical. It is not an exaggeration to call it the earth!"
"Senior, the kid has many questions, but I don't know how to ask!"
"Not busy, look at the starry sky, I have to regain some strength, otherwise I can't speak!" Chen Tuan said.
When Li Yifei was puzzled, he saw the starry sky suddenly turning, as if the stars were moving. After a few breaths, the starry sky suddenly stopped, and then gathered together, rushed towards Chen Tuan, and watched Chen Tuan raise his hand and pat the Tianling cover, as if it had opened. The trick is to get the starry sky into your body.
All this happened in an instant. Looking at the top of the head, it was already dim and dark again.
With a breath and a breath, Chen Tuan made some changes. He looked younger, but his beard and hair were still white, and there were a lot of wrinkles on his face, but he was a bit more aura.
"It's weird why I am trapped here?" Chen Tuan's voice sounded a little more emboldened, and Li Yifei shook his head when he heard the words, "The kid doesn't know!"
"Since you have been in this world for a while, you must have heard of the war between human and animal repair hundreds of years ago?" Chen Tuan asked.
Li Yifei nodded and said, "Know some!"
"I was injured after that big battle, or I deserved to die during that big battle!" Chen Tuan said.
"Uh... so serious?"
"After a long battle, too many human cultivators died. Whether it was human cultivator or beast cultivator, both sides were severely injured. Moreover, after the war, the whole world was destroyed. Some cultivators who remained at that time thought To remedy it, but after so many years, I already know the answer!"
"Can't save it?"
"No, it can be saved, but it takes time. This time may be thousands of years or tens of thousands of years. In short, it is not something I can save!" Chen Tuan's body is still changing, and he seems to be constantly getting younger .
Li Yifei nodded again and again, and said: "It can be better. It is better than throwing an atomic bomb on the earth. That nuclear radiation can last for tens of thousands of years, and people will die soon after they touch it!"
"Nuclear radiation, what is that?" Chen Tuan asked.
Li Yifei had no choice but to explain, and by the way, to mention the development on the earth. In the past few hundred years, the science and technology tree on the earth has been spotted and it has developed in another direction.
"I know the ship, the bigger one is the smaller one, but...what is an airplane?" Chen Tuan asked without understanding.
Li Yifei touched his nose. At this time, he had already sat down, and Chen Tuan had also come down from the stone platform. The two sat on the ground, like old friends for many years, nodded and said: "Doesn't this world also have a magic weapon for flying? The flying sword is also included. The development of science and technology on the earth uses petroleum and other things as fuel to control extremely complex machines to fly into the sky."
"Oh!" Chen Tuan nodded and said, "Unfortunately I can't go back, otherwise I want to see the earth hundreds of years from now, but what do you mean by atomic bombs?"
"That’s more complicated. Simply put, everything in the world can be classified as atoms, or even smaller things. Atoms are like the smallest particles we can feel, and they are also things that make up everything in the world. Atoms can explode. , After exploding, there will be a huge power... so after some substances explode, the power is greater, and countless such substances explode, that is the power to destroy the world!"
"I haven't heard of it. According to what you said, ordinary people on the earth have thoroughly studied time and everything through their own minds?" Chen Tuan said curiously.
"It's almost like this, but it has been extended to all aspects of life, and computers have also been developed. Such machines are more powerful than human brains on a certain level, such as arithmetic. In terms of computing power, I can't compare them. of!"
"Talk about it!" Chen Tuan looked at Li Yifei with great interest, took his hands twice in his arms, and was slightly stunned, only to realize that he had no longevity, let alone alcohol.
"Are you going to...drink?" Li Yifei seemed to have guessed it. After all, the other person was a skeleton transformed into an adult, and he might not have to catch lice.
"Do you have?" Chen Tuan's eyes lit up.
Li Yifei nodded, and took out two jars of wine from the storage ring. One jar of each was smashed into the sealing mud, and one jar was handed to the ancestor Chen Tuan, who grabbed it with one hand and took a mouthful.
"Yes, good wine, some years." Chen Tuan raised his head and smiled and waved his hand: "Go on, I haven't spoken to anyone for many years, let alone come from the'earth', I want to hear about your side. ."
"Okay!" Li Yifei also took a big sip, wiped his mouth, and said, "The computer is too complicated to say, but in simple terms it is a machine that uses the principles of electronics to process data according to a series of instructions. A computer can be divided into two parts: a software system and a hardware system. Of course you may not understand these vocabulary."
