Lin Mi has not been to class for three days because of a fever.

On Friday morning, Limmy cleaned himself up and walked out of the house with a piece of bread. However, because this area is a wealthy area, even though it is time to go to work, there are not many cars and people on the road.

Lin Mi nibbled on the bread and moved unhurriedly in the direction of the school, his heart going up and down. Because it won't be a few minutes...... I'm going to see those nasty people at school again.

Thinking of this, Lin Mi sighed helplessly, and then looked a little dazed.

......

Jingle bells.

Lin Mi stood dizzily at the door of the classroom and looked in...... The classroom was silent, and the students were all doing the exercises in their hands with their heads down.

The teacher stood solemnly on the podium and glanced at Lin Mi.

Lin Mi nodded, took the initiative to put his phone in the phone bag next to the podium, and returned to his seat. After sitting down, Lin Mi took out his book, and then subconsciously looked back......

Then she froze.

Why is that seat empty? Why didn't Jiang Ruo come to class?

With a heart full of questions, Lin Mi stayed up until the end of class.

As soon as the bell rang for the end of class, Lin Mi wanted to get up and inquire about Jiang Ruo. But before she could get up, the teacher took the initiative to walk towards her.

The teacher stood in front of Lin Mi, then pointed to Jiang Ruo's vacant position and said, "Jiang Ruo passed away two days ago. ”

What the......

Lin Mi looked at the teacher blankly, his eyes suddenly turned red, but he couldn't shed tears. The teacher patted Lin Mi on the shoulder and said comforting words...... But Lin Mi didn't listen to a word. For the next few lessons, Lin Mi didn't listen at all.

Jiang Ruo...... Jiang Ruo...... Lin Mi drew circles in the textbook, her heart carrying both great sadness and endless loneliness. Jiang Ruo is a childhood sweetheart who grew up with her, and his death is undoubtedly a heavy blow to Lin Mi.

So after class, Lin Mi thought about it and left the classroom and ran back to her house.

......

Limmi's father was a scientist and one of the key members of the important regional R&D organization "Future World". The "future world" has very strict requirements for scientists, either for achievements or for outstanding research and development capabilities.

And in the past few days, Lin Mi's father left Lin Mi at home alone because of some important tasks.

At the same time, he also threw his latest research and development results at home......

Time Elevator.

As the name suggests, the function of this time elevator is to turn back time. This is nothing short of staggering for today's world, and once this research and development is announced, the history of mankind will be rewritten......

But such a powerful thing was quietly placed in Lin Mi's house.

Yes, it has not been announced yet, because of its R&D ...... It's not perfect. So before going on a business trip, his father repeatedly told Lin Mi to stay away from the "time elevator".

But at this time, Lin Mi broke his father's instructions and stood in front of the elevator.

The outer walls of the metal, the gaps in the red light......

Can this thing really turn back time? Limmi's heart fluttered, fantasizing about a hundred possibilities after going back in time...... The best result is that she can prevent Jiang Ruo's death.

Thinking about it, Lin Mi decisively pressed the elevator button.

Thump...... Thump......

The elevator doors opened.

The entire elevator is painted with red paint. Like a normal elevator, it has a button with twenty numbers written on one side......

What do these 20 buttons do? Lin Mi wondered in his heart.

Because...... Their villa is obviously only three floors.

But soon, Lin Mi had the answer in his heart.

Since this is a "time elevator", then ...... Do these dense buttons represent a backward time?

One layer, is rewind the day ago. Two floors, is rewind two days ago...... And so on, twenty floors, is going back twenty days ago?

Lin Mi thought for a moment and pressed the number 20......

On the screen in the center of the elevator, a display began to appear. One, two, three, four....... Every change in numbers represents a reversal of time. Lin Mi felt no vibrations in the elevator, as if the elevator had never moved.

Also...... After all, the villa is only three floors.

After a while, the elevator doors slowly opened.

Lin Mi forcibly suppressed his beating heart, and then walked out of the elevator trembling......

Or their own home.

"Limmy, what are you doing here?" Father scolded and walked over.

"Daddy, I'm ......"

But before he finished speaking, Lin Mi was stunned.

Father?

Didn't my father go on a business trip?

Don't...... This is the father 20 days ago?

Don't...... That "time elevator" was really successfully developed?

Then Lin Mi showed an embarrassed smile with a chaotic brain, "Ah, I'm just...... Come and have a look. ”

"I've said it a few times, you can't enter this hall." The father looked angry, "Go back to your room!" ”

"Okay, okay." Lin Mi hurriedly agreed, and then left his father's sight.

Oh my God, it really worked......

After Lin Mi got out of the elevator, he hurried to the door of the villa.

The sun in the yard is so warm...... But Lin Mi knew that this was the last residual temperature. Because it rained in the city for the next ten days.
