"Just like Qin before! He ended, even Han, and Han would end the day!" Geng Xiaofan explained patiently.

"What?" Liu Fei'er couldn't accept it at all and grabbed his hand excitedly.

"Qin was destroyed because of his tyranny. Emperor Gaozu killed the snake and rebelled, Thanos, and established the Han Dynasty! Could it be that the Han Dynasty also had tyranny?" Liu Fei'er also learned "history".

"Han is not considered tyranny, but it was defeated by foreign relatives interfering in politics! Not to mention the distance, in a few decades, Wang Mang, who abolished the Han Emperor and established the New Dynasty. Unfortunately, it was not long before he was overthrown by Emperor Guangwu and restored the Han Dynasty, but the capital was changed to Luoyang, which was called the Eastern Han Dynasty in history."

Geng Xiaofan said, thinking, not knowing whether Wang Mang and Liu Xiu were born now. It would be great if Jingyan's sister was here, she knew much more about the history of the Han Dynasty than herself.

"You, do you really know the future?" Liu Fei'er's voice trembled.

"Believe me, I have mastered the cultural knowledge of five thousand years since the history of mankind. You have also seen that I can easily cook salt and make wine. I will have a lot of them, but many may not be realized at all now."

Liu Fei'er sat up, she was a little excited, wondering if she should believe Brother Xiaofan's words.

"Fei'er, are you scaring?" Geng Xiaofan couldn't help but sit up.

"Why can you come back?" Liu Fei'er suddenly asked the idea.

"I don't know. Even the technological level in two thousand years cannot explain these. But if it cannot explain it, it does not mean that there is no. There was a scientist in our era who proposed a theory of relativity that can be explained in theory, but no one can achieve it. So, I said, I don't know why I can come back."

"What is his theory?" Liu Feier asked anxiously.

"It's too difficult to understand, and I can't explain it clearly. It's probably the relationship between time and speed and quality. When speed exceeds a certain limit, time will flow backwards. That's probably what it means."

Geng Xiaofan couldn't explain the theory of relativity to Liu Feier. Whether it was in the narrow or general sense, he only knew a general idea, how could he explain it clearly?

"Speed, what is speed? What is the mass?" Liu Feier seemed particularly interested.

"Mass, you can simply understand it as weight. Speed, speed is the distance traveled per unit of time." Geng Xiaofan knew that he explained this, but Liu Feier didn't understand it at all.

"For example, how far your horse can run in an incense stick is called speed. Some horses run far away, some horses run close, so we say that some horses are fast, and some are slow." Geng Xiaofan tried his best to make his explanation easy to understand.

"I understand, there is a BMW that travels thousands of miles a day and a horse that travels eight hundred miles a night, right?" Liu Feier has a strong understanding ability.

"Yes, this is probably what it means. The theory of relativity means that if the speed exceeds the speed of light, time will flow backwards." Geng Xiaofan was still very satisfied with Liu Feier's understanding ability.

Then explain the speed of light to her.

"Fei'er, you light a candle and the light illuminates the house in one go. You can't feel its speed, but it also has speed. This speed is too fast, so you can't feel it. Moreover, there is nothing in this world, including two thousand years later, that can exceed the speed of light. So, that theory is just a theory."

"But it is true. Otherwise, you can't come back here! Right?" Liu Feier was very smart and said her conclusion according to Geng Xiaofan's ideas.

"Yes! Fei'er, I like your cleverness!" Geng Xiaofan was happy. Sister Zhaojun believed in herself, purely out of feelings, while sister Fei'er believed in herself, believed in her theory.

"Then why are you going home?" Liu Feier finally returned to the root of the problem.

"The theory of relativity has been studied a lot in theory, and many scientists have put forward various ideas. The most mainstream view is the wormhole theory. Time and space are distorted. One time node and another time node are connected together for some reason to form a channel."

"So, you came through that passage."

"Yes, this is the most credible explanation. But I don't know where this channel is and when will it be."

"So, it's hard for you to find your way home!" Liu Feier directly expressed her "conclusion".

"Yes! I may never be able to go home again."

"So, you are confused. You don't know if Sister Jingyan has come through the passage with you. Moreover, even if she comes, you don't know where she is and what will happen! You don't know how you can go back or whether you can go back!"

Liu Feier completely understood.

"So, Fei'er, do you still dare to love me?" Geng Xiaofan especially likes Liu Fei'er's cleverness.

"Brother Xiaofan, I will accompany you to find Sister Jingyan. If you find her, you will be together. If she really doesn't come with you, you will stay and don't go back, okay?"

"Fei'er!" Geng Xiaofan was so moved that he could not express himself. Fei'er was so smart and so beautiful! She was simply perfect!

"But if you decide to stay, you can only love me! You must be better to me than Sister Zhaojun!" Liu Feier added.

"Fi'er!" Geng Xiaofan was a little surprised. Why did Liu Fei'er touch Sister Zhaojun?

"Sister Zhaojun told me that when you were rescued back to Yunzhong Station and were unconscious. She said, she likes you! You are her lifelong spiritual sustenance. Now, she has entrusted you to me and asked me to take good care of you!"

"You, what did you say?" Geng Xiaofan was uneasy.

"She loves you, just like her sister loves her younger brother. Now she has given you to me, so you can't let your sister down." Liu Feier was particularly serious.

"Me, I..." Geng Xiaofan felt a split headache!

"Brother Xiaofan, as long as you are well, sister Zhaojun and I will be happy." Liu Fei'er's eyes were bright and clear.

"Fei'er!" Geng Xiaofan couldn't help but hug Liu Fei'er in his arms. Everything that happened to the big man was so unexpected!

"Brother Xiaofan, let's sleep for a while! It's almost dawn, it's dawn, and there are still many things to do!" Liu Fei'er also needs to digest the various "theories" she accepted tonight!

Geng Xiaofan had nothing to say. He didn't believe it very much when he traveled through time magically. However, the two closest people to him believed in him!
