Xu Zhan stood in front of the podium, looking at the excited expressions of the leading reporters in the audience, and at Song Qinghui who was walking towards him, completely stunned.

Song Qinghui pressed his shoulder, signaled him not to be nervous, and said to everyone in a somewhat ridiculous tone: "It seems that Xu Zhan's composure in his speech just now was pretended, and as soon as he finished his speech, he revealed his true form. ”

There was a good-natured laugh in the lecture hall.

"Xu Zhan is also an old acquaintance of everyone, and the media have been interviewing him all day for almost ten years, I think everyone here has already been asked what they want to ask, and it is also very difficult to find a question that Xu Zhan has not answered. Song Qinghui saw that Xu Zhan hadn't come back to his senses yet, so he naturally helped him ease the atmosphere again, and at the same time handed him a look and told him to step down quickly.

The windows of the lecture hall are installed very high, and rays of sunlight shine through the windows.

A sunny day, without a hint of post-rain haze.

Xu Zhan looked at the time on the screen in a daze.

November 19, 2018 at 3:03 p.m.

Time hasn't changed, the world has changed.

Song Qinghui saw that he hadn't stepped down yet, so his eyelids were about to cramp. In desperation, he could only step forward and gently push Xu Zhan and let him step down, "Xu Zhan still needs to make some preparations for the future laboratory visit, and I will continue the report below." ”

After Xu Zhan was pushed a few times, he finally walked off the stage like a puppet.

Song Qinghui's voice disappeared behind the closed secret door, and Xu Zhan sat on the khaki fabric sofa in the lounge, his eyes straight.

What exactly is going on, is he dreaming now, or was he dreaming before?

Xu Zhan turned his head and saw his own reflection on the clear window glass.

It was a young man with a short haircut, and he looked fresh and capable. "He" wears a crisp midnight blue suit suit, a white shirt and a very formal black silk tie, and a more mature outfit that makes him look older than his actual age.

His face was the same as his own, only fairer.

Looks like a nerd who spends all day in the lab.

This is indeed me, a different version of myself.

The laboratory assistant, who had been waiting in the lounge, handed Xu Zhan a glass of warm boiled water to Xu Zhan, who was in a daze. He took the cup, politely said thank you, and then leaned back on the sofa with the glass in his arms, closed his eyes and took a deep breath, forcing his frozen mind to turn.

First of all, he was pretty sure he wasn't dreaming.

If he insisted on characterizing these things, Xu Zhan felt as if he had suddenly fallen into another parallel world. In this world, he is not a poor courier who failed the college entrance examination and can only retake the exam by himself, but a successful and admired scholar.

What's more, the little uncle Song Qinghui did not die.

Xu Zhan tried to think about whether he had more memories of this world in his mind, but apparently he didn't.

The little assistant looked at Xu Zhan, who was tired, a little nervous, according to the original plan, Xu Zhan should stay until the end of the ceremony, and then personally take everyone to visit the laboratory. But probably because he was tired from preparing for this speech in the past few days, Professor Song asked him to take a break early. The little assistant reminded in a whisper: "Brother Zhan, there is still about half an hour, and everyone is going to visit the laboratory." If you really want to rest, why don't you go to the lab? ”

Xu Zhan nodded, pretending to answer naturally: "Let's go back together." ”

The experimental assistant answered and took the initiative to open the door of the lounge for Xu Zhan.

Xu Zhan slowed down and walked side by side with his experimental assistant, carefully observing his movements and changes in demeanor to determine which direction he should go.

Until he finds out why he traveled into this world and finds a way to go back, he doesn't want to reveal that he is not the original "self". If he behaves like this, there is a high probability that he will be sent to a psychiatric hospital. If he can't go back to his original world, won't he have to stay in a mental hospital for the rest of his life?

Xu Zhan laughed at himself, feeling that he was so calm that it was ridiculous at the moment.

No matter how picturesque Kionggyo University is, he has no intention of appreciating it. He didn't know anything about this world now, and he didn't know how this parallel world differed from the previous world. What kind of personality, hobbies, and habits does you have in this world?

Different from the laboratory building of the medical school next door, which has a ghostly atmosphere at all times, a large number of holly greens are planted under the laboratory building of the Department of Pharmacy, which makes the entire laboratory building of the Department of Biology still look vibrant.

Building 7 is a small two-storey building that stands out from the crowd among laboratory buildings with the same specifications.

The windows of the laboratory building are clearly polished, and through the windows you can see the rows of specimens and petri dishes neatly displayed in the room. There are orchid notoginseng planted in the flowers on the side of the stone path, and the orchid notoginseng in winter has no flowers, only slender leaves and clusters decorate the path, and the water droplets roll on the green leaves.

The assistant "Zhang Shaojie" told Xu Zhan that this independent small building belonged to Song Qinghui in name, and in fact it was completely used by himself.

The "Xu Zhan" of this world not only missed the college entrance examination, but also skipped a grade. In four years, I became a second-year graduate student, doing experiments that only doctoral students and professors are capable of doing.

Xu Zhan felt incredible.

He never thought that just because of Song Qinghui's opportunity, he would have such a drastic change in himself in these two worlds.

This is only four short years, Xu Zhan can't imagine what he will be like at that time if he goes to the farther future.

Did he waste just four years? No, he wasted his whole life.

Zhang Shaojie opened the door of the laboratory and let him in, Xu Zhan wanted to pretend to count the equipment with him, but he refused, "Brother Zhan, you should save some time to rest, Brother Qinghui just sent a text message saying that you stayed up late last night to write a speech." I can handle these routine checks, so you can rest assured. ”

Hearing this, Xu Zhan breathed a sigh of relief, and followed the direction of Zhang Shaojie's finger to see the stairs on the second floor, and it seemed that the lounge should be located upstairs.

The first floor of the laboratory building is modern and must have undergone many renovations and reforms, but the second floor, which served as a reference room, is still old. The stone slabs embedded in the staircase look like they looked like they were decades ago, and the walls are hung with portraits and profiles of ancient miracle doctors, as well as some group photos of teachers and students.

Xu Zhan wasn't in the mood to study those things in detail, there was only a small space, only four rooms, the one facing the stairs was the largest one, and the rest room was arranged at the end of the corridor where few people disturbed.

What if you just slept in the lounge and woke up and went back to the world?

Thinking to himself, Xu Zhan was just about to twist the handle of the door of the lounge, but there was a sudden "ding" sound on his body.

He was stunned for a few seconds before he realized that the voice was coming from his trouser pocket.

I looked down and touched my pants pocket, it was a brand new mobile phone. Xu Zhan was still a little uncomfortable with such a clear and uncracked screen for a while, and he tried to unlock it.

Fortunately, the world's own unlocking gesture has not changed. It seems that he can expect that in other details, "himself" is also similar to the original.

The new information was sent by Song Qinghui.

"I'll help you delay the lab visit for ten more minutes, you have a good rest and adjustment, and I'll still explain it later." ”

Xu Zhan suddenly became alert.

What kind of joke are you asking him to explain the experiment? That's absolutely not okay! He didn't want to mess up his work as soon as he "crossed over" himself and messed up his work before he could say a few words to Song Qinghui.

Xu Zhan hurriedly lowered his head and edited the information: "Brother Qinghui, I haven't been in a good state recently, you can see if this task can be done by another person." ”

As soon as Xu Zhan wanted to press "send", the ground suddenly trembled, the entire wall was falling down at a speed visible to the naked eye, the stairs behind him continued to collapse crookedly, and the floor under his feet shattered into several pieces, Xu Zhan couldn't help but reach out and grab the stair railing.

This scene was almost exactly the same as what Xu Zhan had encountered in the lecture hall just now!

What's going on?

The frames hung on the wall finally broke away from the wall and fell to the ground as they tilted more and more. The glass of the picture frame was shattered by falling to the ground, but in the process of shattering, the pause button was pressed, and one by one, the half-broken picture frame hovered in mid-air. The sight was eerie.

Is he going back?

Xu Zhan clung to the railing of the staircase, regardless of whether it was ugly or not, and slammed himself on it like a drowning man holding driftwood, hoping that the world would be completely transformed before he ran out of energy.

But at this moment, Xu Zhan's ears heard the piercing horn of a police car.

A double image appeared in front of his eyes, both the portrait of the old Chinese medicine doctor on the wall of the laboratory and the scene of "another" world......

I'm being escorted into a police car by two policemen!

"Xu Zhan, my lawyer has a way to keep you in prison for the rest of your life!" Sun Kang's roar came from behind his ears.

Xu Zhan turned his head and saw that Sun Kang's phantom was getting clearer and clearer, only to see that his eyes were red, one hand was covering his nose with a handkerchief, his white shirt was covered with mottled blood, but his face was a distorted smile.

This is my original world? But wasn't I in the lecture hall before? Why am I arrested?

The confusion and heaviness weighed down his breath, and for a moment, his mind was clearer than ever.

Does he want to go back to this world where Song Qinghui died in vain?

Is he going back to the world where he is about to spend his life in prison?

He- of course not!
