700 years later

"Why can't it be me." The roommate was very dissatisfied, "Do you think I would like to come on a business trip? You didn't force me to come here, I asked why you didn't come to meet yourself, you trash...you know Did you say something?"

"What did I say?" Cheng Zhang asked.

"You said you were going on a date, and it's not like I'm a single dog who has nothing to do all day long. What's the matter here!" the roommate said, "If you didn't threaten me to deduct my salary, I really want to kill you."

"I didn't know what to say at first," Cheng Zhang said, "Thank you, I know now."

"..." The roommate was speechless, "The time loop is too deceitful."

"So how did you become my colleague?" Cheng Zhang asked.

"It's not that you tricked me into coming here," said the roommate, "I failed the postgraduate entrance examination and you just tell me that I have a very relaxed and happy job that allows me to travel frequently. When I heard about such a good thing, I thought You dog is finally kind enough to take care of your brother, but you often work overtime and rest time is unstable, and it’s not convenient to tell people, and you can’t even find a partner on a blind date. You..."

The roommate was so angry that he almost murdered his future boss.Cheng Zhang avoided it expressionlessly, thinking to himself, no matter what job he does that sounds lofty and interesting, he cannot escape the fate of a social animal.

Cheng Zhang asked again, what are you doing here?

The roommate finally remembered the business and threw him the prepared things.

"Here, I just invented the space-time shuttle watch, and I'll bring it to you right away." The roommate said, "I was afraid of being late, so I didn't know how long I've been waiting for you, you trash."

Cheng Zhang unwrapped the package and took it out, and it turned out to be what he was thinking about just now.

"You also said that you don't know anything now, you don't have common knowledge of technology, and you wrote an instruction manual in it," said the roommate, "read it yourself, you can always understand what you write!"

That watch, a new watch just produced, a portable time travel machine, is now in Cheng Zhang's own hands.

"When did I tell you to carry out this task?" Cheng Zhang finally understood how to play this game, "Tell me the time and place."

Sure enough, the roommate also understood Cheng Zhang's purpose, he hesitated and didn't want to say it.

"I'm not in a hurry," Cheng Zhang folded his arms. "Anyway, I haven't become your boss yet. What kind of organization do you belong to, the Space-Time Administration? If you don't tell me now, I won't be able to report to you in the future." I am not responsible for the problems that arise when you convey the mission."

The roommate didn't expect Cheng Zhang to be cunning enough now, and he explained the time and place through gritted teeth.

"It turns out that humans really invented the time machine," Cheng Zhang thoughtfully, "It will take so many years."

But it doesn't matter, there is hope, that is the best ending.

"What should I do now?" Cheng Zhang asked, since he was at a loss, his future self must have arranged the next step.

The roommate said: "The car is reserved for you, and it will be here soon. Go to the adoption center and adopt a child."

"Child?" Cheng Zhang was puzzled, "Why do I have to raise a child again?"

"A couple are going on interstellar exploration, and the destination is very dangerous. They decided to send their child out for adoption." The roommate said, "I have already applied for you. Originally, you were not allowed in this situation, but In order to maintain the harmony of time and space, I gave you special approval."

As he spoke, he suddenly laughed: "I found out that it's really interesting to keep people secret. Now I'm happy to see you anxious and don't understand what's going on. Well, I won't bother you, you The baby to be adopted has already been named by the parents, and his name is Cheng Zhang."

Of course he didn't show kindness, but if he went on like this, he would really be beaten by Cheng Zhang.

When Cheng Zhang was young, he always had some regrets about being adopted.He always wondered why his parents abandoned him, thinking of thousands of reasons, and never thought that they were going to explore space.What's more, he didn't expect that he threw himself at the door of his adoptive parents.The adoptive parents did not hide the truth from Cheng Zhang. He was very clear about the time when he was picked up. According to the instruction manual, that day had already arrived and the time was about to arrive. Cheng Zhang was standing in front of his house with the child in his arms. There was a knock on the door.

There was a man's voice from inside the door, drunk: "Who is it?!"

Then he pulled out the chair, and a wine bottle fell to the ground and broke. Cheng Zhang hid in the dark, watching the man open the door and staring blankly at the baby at his feet.

If he hadn't known that this was his adoptive father, Cheng Zhang would have thought about whether he was entrusted to someone else. The man in front of him didn't look like he could be a good father, but he would sell the child for wine money.

Fortunately, the man still picked up the child and coaxed him clumsily: "Don't cry..."

People really can't predict what they will become.The adoptive father in Cheng Zhang's memory didn't drink alcohol, and he didn't lose his temper very much. When he was free, he would chat with him and teach him how to cook.If Cheng Zhang hadn't met Dou Yu, what kind of person would he have become?It is not necessarily possible to think about such a grand topic in the future, nor to travel between time and space, there are infinite possibilities.These were all brought to him by Dou Yu, but Dou Yu...

Relieved, Cheng Zhang began to think about where to go next.

He thought about it, and found that he was not very capable of the pursuit of a time traveler, and he felt a little uncomfortable after only one day in the 90s.The main problem is that he has no money, and he has not had a bite of food until now.Maybe it's time to go back to 2018 and still have money in my bank card.

Cheng Zhang took out his watch again, trying to adjust the jumping time.

"Huh?" Cheng Zhang saw some unexpected information.

This manual is very long, and even marked with various handwritten information, such as "just see this this time, and read it next time when you think about it."Cheng Zhang was not obedient at the time, glanced back a few times, and found that he really couldn't understand, and didn't know what was written, so he gave up.This time, looking back from the place where the cutoff was last time, there is a series of numbers written, which Cheng Zhang entered into the watch according to the time, latitude and longitude, and even the altitude of landing. The strange thing is that the time has disappeared compared to Cheng Zhang. That day was a day or two earlier, and the location was not the university dormitory where Cheng Zhang was originally staying.

After hesitating for a moment, Cheng Zhang decided to still have confidence in himself, no matter where or who he is, they are all fates to face.

Moreover, Cheng Zhang had a hunch this time, at least he would not run into his unlucky roommate again!

Cheng Zhang pressed it, and after a while, he saw a familiar person.

"You are finally back." Dou Yu said.
