Chen Tuan seemed to be really old. Although he woke up from his deep sleep and slept for fifty years this time, even less than he slept on the earth, he would definitely not have been like this before. At this time, he seemed a little dull. After hearing Li Yifei's words, he remained silent for a long time.

Li Yifei seemed a little nervous and excited. If the person in front of him was really the ancestor Chen Tuan, he would probably be a legendary figure in both worlds, especially on earth. He witnessed the changes in that world. Li Yifei also knew the reasons for the change. Chen Tuan was one of the promoters at that time, but he was trapped in this small mountain at this time? Why is this? Moreover, the ancestor Chen Tuan should also belong to the highest cultivation category in this world. It is logical that he should not be so down and out.

So what is the reason?

Chen Tuan was silent for a long time, as if he was brewing something, and as if he was thinking. The raccoons around him maintained a pious posture, making some screams in their mouths, as if they were chanting scriptures.

"Oh!" With a long sigh, Chen Tuan came to his senses again. His old face slightly raised and looked at the top of his head. Li Yifei followed his gaze and found that there was another mystery above his head, like a starry sky. As the raccoons recited scriptures, there seemed to be countless floating dust in the air, flashing with light, and the light floated upwards and dotted the starry sky!

This is a star map. Li Yifei confirmed it. He opened his eyes wide and soon saw a few familiar places in the sky. Not to mention anything else, the Big Dipper is the most obvious seven stars.

"Is the starry sky of the earth?" Li Yifei asked.

"Oh, your name is Earth?"

"Because it's a ball!" Li Yifei replied subconsciously, thinking that Chen Tuan probably didn't know that the earth was a ball in that era. Oh no, with his cultivation level, it's probably easy to know that the earth is a ball.

This seemed to be a paradox. Li Yifei hesitated and heard Chen Tuan say: "Yes, the earth under our feet is spherical, so it is not an exaggeration to call it the earth!"

"Senior, the boy has many questions, but he doesn't know how to ask!"

"If you are not busy, look at the starry sky, I also need to recover some strength, otherwise I can't even 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 paused, then gathered together and rushed towards Chen Tuan. Then he watched Chen Tuan raise his hand and slapped the sky cover, as if he had opened the trick and put the starry sky into his body.

All this was just something that happened in an instant. Looking at the top of your head, it was already dull and dark.

During the breath, Chen Tuan changed a little. He looked younger, but his hair and beard were still white, and there were many wrinkles on his face, but his momentum was a little more.

"It's strange why I was trapped here, right?" Chen Tuan's voice sounded more confident. Li Yifei shook his head and said, "I don't know!"

"Since you have been in this world for a while, you must have heard of the war between human and beast cultivators hundreds of years ago?" Chen Tuan asked.

Li Yifei nodded and said, "I know something!"

"I was injured after that war, or I should have died during that war!" Chen Tuan said.

"Uh...so serious?"

"After a long battle, too many human cultivators died. Whether it is human cultivator or beast cultivator, both sides were seriously injured in their vitality. After the war, the entire world was also destroyed. Some of the remaining cultivators at that time were thinking about remedies, but over the years, I already knew the answer!"

"Can't save it?"

"No, I can save it, but it takes time. This time may be thousands of years, maybe tens of thousands of years. In short, it is not something I can save it!" Chen Tuan's body was still changing, and he seemed to be constantly becoming younger.

Li Yifei nodded repeatedly and said, "It's enough to get better. It's better than throwing an atomic bomb on the earth. The nuclear radiation energy lasts for tens of thousands of years. People will die soon after they encounter it!"

"Nuclear radiation, what is that?" Chen Tuan asked.

Li Yifei had no choice but to explain and mention the development on the earth. Over the past few hundred years, the scientific and technological trees on the earth have already developed in another direction.

"I know the boat is bigger and smaller, but...what is the plane?" Chen Tuan asked incomprehensible.

Li Yifei touched his nose. At this time, he had already sat down, and Chen Tuan had already come down from the stone platform. The two of them sat on the ground, as if they had been old friends for many years. He heard this and nodded, saying, "Don't there be magic weapons for flying in this world? Flying swords are also included. The technological development on the earth, using oil and other things as fuel to control extremely complex machines to fly into the sky."

"Oh!" Chen Tuan nodded and said, "It's a pity that I can't go back anymore. Otherwise, I would like to see the earth hundreds of years later, but what are the atomic bombs and other things you are talking about?"

"That's even 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 all things in the world. Atoms can explode, and after they explode, they will have huge power... So after some substances explode, they are even more powerful, and when countless such substances explode, they are the power to destroy the world!"

"I haven't heard of it. According to what you said, the ordinary people on Earth have studied time and everything through their own minds?" Chen Tuan said curiously.

"That's about that, but it has extended to all aspects of life, and has also developed computers. These machines are more powerful than the human brain at some level. For example, arithmetic, and in terms of computing power, I can't compare to them!"

"Tell me!" Chen Tuan looked at Li Yifei with interest, took his hand in his arms twice, and was slightly stunned, before he realized that he had already lost everything, let alone drunkenness.

"Are you going to... drink?" Li Yifei seemed to have guessed that after all, a skeleton transformed into a human, so he might not have to catch lice.

"You have?" Chen Tuan's eyes lit up.

Li Yifei nodded, took out two jars of wine from the storage ring, one jar of each, slapped Kaifeng mud, and handed it to Chen Tuan Ancestor Chen Tuan. The latter grabbed it with one hand and raised his head.

"Not bad, good wine, some years." Chen Tuan raised his head and smiled, waved his hand: "Continue to say that I haven't talked to anyone for many years, let alone the 'earth'. I want to hear what happened over you."
