"Aunt Zhou...... Ah, comrade, what about the people in this house, why didn't there be any response when I knocked on the door?" Duan Yun asked.

"Who the hell are you?" the woman's expression became wary.

"That's right, I have a comrade-in-arms named Duan Zhiqiang, after demobilization, he returned to work in the pharmaceutical factory, and the address left for me is here, so I came to see him this time. Duan Yun raised his eyebrows and said.

Duan Zhiqiang is the name of Duan Yun's father in his previous life, his father was a soldier in his early years, and after he was discharged from the army, he was arranged to work in a pharmaceutical factory.

"There is no ...... named Duan Zhiqiang here" The woman frowned when she heard this, and then said: "There used to be an old man living in this house, who died a few months ago, and the house is now empty, no one lives in it......"

"What!?" Duan Yun was stunned when he heard this.

"Taotao, let's go, Mom will lead you to fire. The woman didn't pay any attention to Duan Yun, closed the door, and was about to leave with the child.

"Comrade, wait!" Duan Yun hurriedly shouted to the woman again.

"What the hell do you want to do, my man is at home!" said the woman, frowning.

"Ah, it's okay, it's okay!" Duan Yun waved his hand to signal her to leave.

Aunt Zhou's husband is a well-known second-rate son in the factory, and Duan Yun doesn't want to cause any trouble here.

But Duan Yun was a little unwilling, he had to figure out the situation in his family.

After thinking for a while, Duan Yun knocked on the door of another house next to him.

It was an old lady who opened the door this time, and Duan Yun recognized at a glance that she was his childhood neighbor Grandma Liu.

"Are you ......" After Grandma Liu opened the door, she glanced at Duan Yun and asked.

"Ah, I'm Comrade Duan Zhiqiang's comrade-in-arms who lives next to me...... Duan Yun introduced himself.

"This family is not surnamed Duan, but surnamed Wang, who died in October last year, and his son is in the army...... No one lives here now. Grandma Liu said.

"Uh. When Duan Yun heard this, his face suddenly showed a look of disappointment.

Obviously, what Aunt Zhou said just now is right, there is indeed no one living here.

This is completely different from what Duan Yun remembers.

In an instant, a word flashed through Duan Yun's mind, and that was the 'butterfly effect'.

The so-called butterfly effect is a long-term huge ripple effect of small changes in the initial conditions that can lead to the whole system. It is a chaotic phenomenon, which shows that there are fixed numbers and variables in the development of any thing, and the development trajectory of things in the process of development has laws to follow, and there are also unpredictable "variables", which are often counterproductive, and a small change can affect the development of things, which proves that the development of things is complex.

The most common description of this effect is: "A butterfly in the Amazon rainforest of South America, with a few occasional flaps of its wings, can cause a tornado in Texas, USA, two weeks later." The reason for this is that the movement of the butterfly's wings causes changes in the air system around it, and produces a weak air flow, which in turn causes the surrounding air or other systems to change accordingly, thus causing a chain reaction that eventually leads to great changes in other systems.

Duan Yun has already had a certain impact on this world when he travels to this era, and his past family is likely to change because of his own crossing!

Duan Yun was still a little unwilling, and he began to ask the neighbors upstairs and downstairs again.

But the results were the same, they all said that Duan Yun's house used to live in an old man who had been dead for several months.

Duan Yun's mood suddenly sank.

Subsequently, Duan Yun went to his grandfather's house, which was also in this factory.

However, Duan Yun still didn't find anyone this time.

Duan Yun was a little anxious, he didn't expect that he had finally returned home, but he hadn't even found a relative.

The sky gradually darkened, and Duan Yun had no choice but to do so

At that time, staying in a hotel was not like in later generations, you could live with an ID card and pay money, and the hotel was subject to the organization's dispatch, so that you could live in the east and live in the west.

At that time, there was a signboard of "Beijing Hotel Introduction" at the exit of the platform of Beijing Railway Station, and there was a wooden pavilion, and there was a long queue of business travelers, and the people in the pavilion only gave a list after checking the letter of introduction of the unit, with the name of the hostel written on it, and the hotel arranged accommodation with the letter of introduction of the unit and the list. Where to live or where to live, it's completely Qiao Tai's chaotic mandarin duck spectrum, and if you can't get it, you have to live in the basement bomb shelter.

Later, from 79 years ago, with the Hong Kong businessman Fok Yingdong building the first 34-storey White Swan Hotel in Guangzhou, becoming the first hotel for all people, hotels across the country began to follow suit and open their doors to the people.

In the past two years, he didn't have an ID card, Duan Yun just showed his work card, and after paying a deposit of 15 yuan, he lived in the guest house of the pharmaceutical factory.

Lying on the bed in the hotel, through the glass, the whole sound of cannons could still be heard outside the window, Duan Yun tossed and turned, and it was always difficult to sleep.

It was hard for him to accept that his parents and all his loved ones had been wiped out.

There was an indescribable sadness in his heart, since Duan Yun was reborn, he had always wanted to see his parents and relatives, but then there were no relatives here......

But Duan Yun was also very helpless, some things themselves were not something he could change, and the only thing Duan Yun could do now was to accept such a reality.

It wasn't until the second half of the night that he felt a strong feeling of tiredness, and Duan Yun fell asleep.

The next day, Duan Yun went to the station early in the morning and bought a ticket to Jilin City.

Duan Yun's ex-girlfriend Luo Yanjun's family lives in Jilin City.

The two cities are not far apart, when they were in junior high school, they both went to school in their respective cities, and when they were in high school, Luo Yanjun and Duan Yun were both admitted to the high school of Changchun No. 1 Middle School, that is, from that time, the two became classmates.

At the beginning of the classmates, the two were just ordinary classmates, they were both immersed in their own studies, and they rarely spoke.

It wasn't until the two were admitted to a second-class university in Chengdu with similar scores that they established a relationship in the second half of their freshman year, and then maintained the relationship for more than ten years.

During this period, Duan Yun went to Luo Yanjun's house several times, his home was in the urban area of Jilin City, and he never moved since.

Compared with Changchun, Duan Yun is much stranger to the city of Jilin, although the two cities are very close to each other, Duan Yun has only been to Luo Yanjun a few times.

But this did not prevent Duan Yun's memory, he could still remember the address where Luo Yanjun's house was located.

Duan Yun vaguely remembered that Luo Yanjun's family lived with her parents and grandmother when she was a child, and the house was left by her grandfather, who had passed away a long time ago.

After getting off the bus, Duan Yun quickly found Luo Yanjun's home.

However, to Duan Yun's disappointment, after knocking on the door, Duan Yun learned that this house was not occupied by Luo Yanjun's family.

I asked the neighbors of this building, and none of them had heard of the names of Luo Yanjun's parents......

No, nothing, Duan Yun was completely disappointed......
