In fact, in Charlene Fei's guess, there were some unreasonable things in the first time travel.

For example, she guessed that she was thrown into 2006 during the first time travel of the time machine, while Gao Jun and Time Machine went to the world of a=1.000122. There was a problem here. Why did she come to 2006 in the section a=0.8 during the same time travel, while Gao Jun and Time Machine went to the world of a=1.000122?

The time machine recorder will turn on and record after the time machine reaches its destination. Judging from the world recorded by the time machine, the world that this time machine jumps for the first time is the world of a=1.000122, and does not stay in the section a=0.8, so the appearance of the Shalindong seems a bit incredible.

After thinking about it, Charlene could only attribute it to an inexplicable accident during the process of traveling through time. Was he thrown out of the time machine while jumping to the long river of time? Then he came to 2006 in the a=0.8 section?

Or maybe I did not come to 2006 when the time machine first traveled, but the second traveled? In the time machine's record, this time machine also made a second jump, with the starting point of a=1.000122, and the destination was a=0.8 world!

If Charlene came to the current world during the second time travel, it would make sense within the world line, but at the same time there was another problem - it didn't make sense in time! You should know that the second time travel came directly in June 1993, and both people and physical evidence were there. The time machine was also taken to the basement by Su Caiwei.

How did she appear in 2006?

Troubled! Charlene reached out and rubbed her forehead, feeling that she lacked a flash of inspiration. She couldn't even explain how she came to this world. At this time, she hoped that her father was by her side. If he said that, she would definitely think of the answer to this question!

There is a rule for the jumping of the world line, that is, the one-to-one correspondence. For example, when Su Yuan came over on the time machine, the original world was a=0.799920. At that time, there was only a=0.799920. Her behavior of traveling to December 9, 2012 was actually refreshed based on the world of a=0.799920. In layman's terms, the world of a=0.799920 was erased, and replaced by a=0.899210. The two have sequences. At the same time, there is also an inevitable sequence. A=0.899210 is the evolution of a=0.799920. The time machine's crossing point on December 9, 2012 is an important time node for two consecutive worlds.

The new world a=0.899210, before December 9, 2012, its history is exactly the same as a=0.799920. What was refreshed is only the development after crossing the point.

Taking the arrival of the time machine as an example, from the current known situation, the time machine was first manufactured in the world of a=1.200011, which is also the starting point of the time machine! Then, according to the time machine's records, it jumped to the world of a=1.000122.

Then, the time machine made another jump. This jump. The time machine came to the world of a=0.799920 in June 1993, and was taken into the basement by Su Caiwei and hid it. Then in the world of a=0.799920. Su Yuan used it to make the third jump, reaching a=0.899210. But it should be noted that the jump made by Su Yuan was only on December 9, 2012. The history she changed was only on December 9.

Before this time, there was a second time machine jumping in her basement!

In other words, the second jump of the time machine came to the two worlds a=0.799920 and a=0.899210 at the same time. Although they are two world lines, the history of these two world lines was exactly the same before December 9, 2012.

In terms of existence, the world lines are parallel to each other, and they can form several groups of congestion, that is, the world lines and the world lines are also divided into groups, and they can be closer together, just like a rope tied together, or they can be separated farther and never interact with each other.

The closer one is the convergence of the world line. They have similar development trends and have similar end points in the distant future; the more open the segments, it is manifested as the independence of the world line. Their development does not have the same nature. As the timeline continues, the difference will become bigger and bigger.

For the world, the existence of a world line is just a representation of its development law. There is only one world, and at the same time, it can only express the plot within a world line. If different world lines are integrated according to the development of the plot and the exactly the same historical sections on the world line are integrated together, then they will become lines that start from a starting point and constantly bifurcate.

This model is called a story tree!

The story tree uses the timeline as the key to distinguishing it. For example, the world line was divided into a world line a and β world line in 1995. At the same time, in 1997, the world line a split into two world lines a1 and a2. At the same time, the β world line was also divided into two world lines β1 and β2 in 1997.

So what would happen if a scientist made a time machine that could jump the world line in 2035 and sent this time machine to 1996?

Time opportunity moves along the timeline, and in 1996 in branch a, if the arrival of this time machine does not change history, it will appear in the two world lines a1 and a2 that have not yet been bifurcated at the story tree level, and after the bifurcated, this time machine appears in both the a1 and a2 worlds.

But if this time machine changed history, then a1 and a2 would have no chance to split, because in 1996 when the time machine arrived, the development hopes of a1 and a2 were wiped out together, and the branch a has appeared as a new development a3 different from these two world lines!

By the same token, if the time machine made by the world a1 traveled to 1994, since the a and β world lines bifurcated in 1995, either the time machine does not change history and appears in the a and β branches at the same time. Or the a and β branches are erased together, and replaced by the new bifurcated γ world lines that began to appear in 1994!

The time machine used by Su Yuan has traveled three times, while the time machine in the current basement has traveled only twice. Although the world line values ​​displayed on the second time traveled differently, they are traveled the same time at the story tree level, but the specific situation is analyzed and the data recorded by the recorder is different.

At first sleep at night, the surroundings were surprisingly quiet, with the evening breeze and the waning moon. A cold wind blew, making people tremble. This night was sure to calm down.

Tagore said that if you cry because you lose the sun, then you will also lose the stars. If you are depressed to miss the stars, then you will miss the moon again. Your heart is sharp, not broad. It is persistent at every point, but it is not active.

After re-receiving the time machine to the basement, Su Yuan and Xia Linfei each remembered their thoughts, and there seemed to be a thick confusion in front of them. It turned into pressure, bringing them a deep confusion. This time, the inspection of the time machine made them uncover a corner of the confusion. New confusion arose in the heart.

Su Yuan turned around and looked at Xia Linwo, who was writing something in the notebook, sighed softly. He turned his head and looked out the window. He saw a white light blooming quietly in the dark curtain, and he could vaguely hear the roaring wind.

"It seems that it will snow..." Su Caiwei walked over and said.

"Xiaoyuan, Ye Hao and the others are coming back soon for the New Year." Su Yuan said softly.

The world is too heavy when the flowers are about to bloom. The old dream is too light when the butterfly wants to fly. When it is snowing, she suddenly thinks of the memory fragments she remembers deep in her memory. It was a snowy night. The two of them were walking on the street, standing in the heavy snow one after another, quietly, the girl raised her head.

This scene must be very beautiful when you think back on it now. Before you know it, an arc appeared slightly on the corner of your mouth.

...

February 9th, New Year's Eve.

The moon is over and the years are over, and the old is eliminated and the new is welcome.

Su Mengyuan and Ji Yehao returned from Shanghai a few days ago. Su Caiwei was busy with solid energy all day long and threw the cleaning work at home to Su Yuan, resulting in Su Yuan becoming the daily manager of the Su family. Of course, she was not willing to be outdone, so she packaged and assigned tasks, and pulled Su Mengyuan, Ji Yehao and Xia Linwo to start busy.

The temperature is suitable for New Year's Eve this year, with a sharp crescent moon hanging in the night sky, and stars scattered in the deep sky. In the dark, there seems to be a very experienced chess player who quietly observes the washing of the disk night sky. With a flash of inspiration, he throws a dazzling chess piece in a dark place.

On the first day of the junior high school, stay at home.

On the second year of the junior high school, Su Caiwei took Su Yuan and Su Mengyuan to visit relatives from all over the country. When they came back, Su Mengyuan followed Ji Yehao to visit relatives... She was so busy.

Su Yuanxian had nothing to do at home, so he discussed with Xia Linjie about the time machine and how to avoid technological leakage. The two used their means to persuade Ji Yehao and others to transfer all the technology in the basement to the basement. The key role of the two was the "diary" that recorded the events after 2012.

After the transfer of technology, Su Yuan and Charlene also began to take the initiative. With the powerful functions of Alaya and the assistance of Gaia, the American Adam system, Eve system and even the intelligence network were hit hard, and the recent new network storm has caused a sensation in world public opinion.

In order to avoid getting angry, Su Yuan and Xia Linfei had to act as "terrorists" again and published declarations on "jihad" on the Internet to confuse the public and lead the muddy waters to innocent al-Qaeda, and the Islamic State organization, which was bloody and cruel in later generations than al-Qaeda.

Of course, we are very happy to accept this "great" Al Qaeda and Islamic State. In particular, this Islamic State, as a branch of Al Qaeda, tends to be superior to others. Before that, it was not valued by the international community. However, after this incident, it suddenly appeared in front of people all over the world.

The international community suddenly discovered that this organization called the successor of al-Qaeda, called the "Islamic State", actually has a strict organizational structure. It is not a simple terrorist, but more like a regime institution!

"Sister, what are you thinking?"

Su Yuan quietly looked at the snowflakes that had fallen in the sky, and didn't know what he was thinking in his head. Suddenly he heard the voice of the girl behind him. He turned around subconsciously, but suddenly felt a shock at his neck, and then a cold and tingling feeling extended along his neck to his chest.

"Hahaha..." Su Mengyuan laughed arrogantly.

"You dare to attack me!!"

I don’t know if it was because of the cold snowball or the anger of Su Mengyuan’s sneak attack, Su Yuan’s pretty face turned pale, squatted down and picked up a handful of snow, and then carefully rolled on the ground and rubbed a snowball as big as a basketball.

When Su Mengyuan saw this, his face changed and he hurriedly ran towards the house. Su Yuan was not willing to spare her so lightly, and chased her in with a snowball.
