Song Ziyu knows that the reason why this world can be so pleasant. The reason for this is that he has changed the history of this plane.

Without the influence of polymers in 1936, the world's world line began to move forward in a smooth way, and even in 2210, humanity was still steadily on the path of limiting the development of artificial intelligence.

Song Ziyu walked on the street of R239 and felt the scenery of the new era. In this plane, because of Xihe's deliberate guidance, human beings began to guide human beings to limit computers, intentionally or unintentionally, since the emergence of computers.

The first is the limitation of the world's root group servers, which does not allow too many root group servers on the computer, which fundamentally limits the computing power of the computer, resulting in the iteration of artificial intelligence is difficult to attach.

Because of this! Even in 2210, the world does not seem to be changing much. Song Ziyu took a flight to the southern capital of this world, then entered the old archival library and found a newspaper from 2038.

In the newspaper, there is a record of a marathon in Nandu...... determined the time and place, and Song Ziyu found the anchor point for crossing.

Activating the bracelet, Song Ziyu began the second crossing. The light flickered, and Song Ziyu stood in front of an old house.

This is the former site of the Nandu Archives in 2038, and it is still an ordinary residential building. In 2038, Yu Xia Guo has already undergone a decade-long economic transformation.

Real estate was confined to a high point, and the old town was no longer allowed to be demolished according to the policy, so the old light and shadow of the old city were retained for many years.

This is the old street of Nandu...... Looking at the familiar street, Song Ziyu couldn't help but burst into tears.

There is a way that the flowers are helpless to fall, and the familiar swallow returns. Song Ziyu walked on the familiar and unfamiliar old streets, and walked towards Nandu University step by step.

Snow began to fall in the sky. On the street, a large group of athletes wearing sportswear with number tags on their chests are running along the street towards the distance, and the marathon that passes through the city is in full swing.

Surrounded by pedestrians taking pictures, surrounded by lively and bustling people, all of this is full of humanistic care.

It's so familiar! It's all too familiar! That's where I grew up. …… The snow is getting heavier and heavier.

Song Ziyu wrapped his trench coat tightly, and then walked towards Nandu University. However! Song Ziyu had forgotten.

In its own year 2038, there will be no snow in Nandu. For the city of Nandu, in a hundred years, there may not be a few goose feathers and heavy snow.

Walk through the familiar streets, walk in the familiar old alleys in the south of the city, and turn back to Bachelor's Mansion Street, where the gate of Nandu University is in sight.

Seeing the magnificent marble school gate, Song Ziyu's mood reached a high point again. Walk slowly towards Nandu University.

At the school gate, the security guard in navy blue was jumping and in the snow, as before. Walking to the entrance and exit of the school commuter, Song Ziyu touched himself.

The student ID of yesteryear is long gone. Song Ziyu reported his school registration number and class to the security guard, and then walked towards the school.

The security captain who was pinching the Zhang version of "Golden Vase Plum" snorted: "Classmate, your student registration number is wrong, let me check the list." It's okay not to check, but after a check, the security guard scratched his head and said, "Classmate, there is no such person as you in the history department." Song Ziyu was stunned when he heard this, and he really felt incredible.

But this did not prevent Song Ziyu from entering the school. Now Song Ziyu is far from being a person, bypassing the security guard to the college wall, and then jumped directly and flew directly into the campus.

There was also a bit of a hiccup in this jump, and the two students at the landing position were communicating foreign languages, and they were disturbed by Song Ziyu.

Song Ziyu smiled faintly and said to the disheveled elementary school girl: "The snow is too big, be careful of catching a cold." Then, Song Ziyu rushed to his class.

Passing by the basketball court on the road, Song Ziyu saw it

"Acquaintances". Guo Wei, a big man holding a basketball, walked past him, and Bai Yanyan, who was holding a towel and a soda, was chasing after Guo Wei with small steps.

"Brother, wait for me duck, brother, you have snow on your head." Bai Yanyan, whose little face was red from the cold, was full of Guo Wei, that kind of love and love, that kind of worship and fulfillment, not an actor can act.

…… Song Ziyu passed by the two of them, and Bai Yanyan didn't look at her the whole time. Song Ziyu is sure.

About this world, I don't know Bai Yanyan. Putting away his slightly complicated feelings, Song Ziyu walked into the dormitory Bowang Building.

In the same dormitory, there are several completely unfamiliar faces. This made Song Ziyu very puzzled. After asking, Song Ziyu only knew.

There is no Jiang Zhe, Liu Kun and the like here, and Lu Fang is not a student of the history department, but a big man in the philosophy department next door.

Has history changed? Song Ziyu was slightly surprised in his heart, and had such a guess. With apprehension, Song Ziyu found his former friend Lu Fang, this guy is still short of 5,000 yuan and hasn't paid it back, he doesn't collect debts, he can always reminisce about the past, right?

However, fate once again taught itself a lesson.

"Who are you, classmate? Do we know each other? Lu Fang looked at himself and asked something like this.

"I'm sorry, I may have recognized the wrong person." Song Ziyu left the dormitory in a daze, but he still didn't give up, so he quietly sneaked into the school file management room while the school cadres were not paying attention, and then opened the school file and began to check his name.

Really...... In this world, I was not admitted to NTU. After leaving school, Song Ziyu squatted in the snowstorm and smoked a cigarette.

Then Song Ziyu stood up and called a taxi and went straight to Mu County. Song Ziyu wanted to confirm one thing.

On Yuanta Street in Muxian County, Song Ziyu returned to the tube building where he grew up. Looking at the tube building as in memory, Song Ziyu couldn't help but breathe a sigh of relief.

Walking towards his home, Song Ziyu felt that his feet were trembling. I used to cross planes and time, and my legs were able to stand steadily, but now on the way home, my feet are weak.

This...... It's true...... It's hard to put into words. At this time, it was getting late, and Song Ziyu had just gone upstairs when she met a woman who was stir-frying in the aisle with a cigarette in her mouth.

The woman has a fat head and big ears, isn't she Aunt Chen, her mother's former friend? Song Ziyu was stunned for a moment, and then walked past the woman, who looked at her curiously, but her face showed an expression of complete unrecognition.

Song Ziyu came to the door of his house and knocked on the door carefully. The door of the room opened, and a man with a face full of sighs and stubble stared at him with unkind eyes: "Who are you?" ”

"Who are you?" Song Ziyu was stunned: "Why is it in my house?" The man was stunned, and beckoned to the neighbors: "Let's see, whose relatives are these, is it the wrong door?" Countless pairs of eyes looked up and down the tube upstairs, and Song Ziyu's scalp was numb.
