Professor, your turtle!

When they returned to the ground, there was already a little morning light on the other side of the horizon.

Chen Zhen stayed until the end, standing at the door and looking back at the laboratory that had cost him countless efforts.The room where people come and go is now empty.For some reason, there was a relief like relief in his heart.

He carefully checked the temperature and humidity, confirmed the ventilation system, and then, like the end of a normal working day, he raised his hand and cut off the electric switch.

From near to far, the daylight dome lights are turned off one by one, symbolizing the end of a technological dream.

He didn't retract his fingers immediately, but lightly stroked the wall.

"Hey--"

Chen Zhen turned his head and saw Ji Fan was climbing the ladder with one hand, and waved to him.

The tunnel was dark and damp, and the only faint light came down from the top of the cellar well, dimly illuminating the boy's face.In a daze, he subconsciously blurted out: "Yu..."

"Chen Zhen, let's go!" Ji Fan shouted at him with his left hand in the shape of a trumpet.

"..."

Chen Zhen suddenly came back to his senses, blinked, and then smiled: "Well, here we come."

"Seeing you standing there in a daze just now, I almost thought you weren't going to leave, and it scared me."

"Why?" He shook his head, "It's just a little nostalgic."

It's like going back to a deserted and empty middle school during the holidays, and I can't help but squeeze into the narrow wooden desk and chair for a while.Although the size is completely inappropriate, and the school days are not all happy memories, the ink fragrance of printing oil is lingering in my mind, gloomy and gentle, which makes people unable to let go.

Ji Fan climbed out of the well first, turned around and gave Chen Zhen a hand, and the two walked into the grove one after the other and joined the crowd.

"Is it all over?" Xun Jiangyun asked.

Chen Zhen nodded.

"You come?"

"No need." Chen Zhen turned his face away, not taking the detonator handed over by the other party.

Xun Jiangyun smiled and pressed the button casually.

The world was silent for two seconds, and then, a very dull rumbling sound came from the depths of the earth.

The laboratory was dug too deep, even if the entire building collapsed, it would not have much impact on the ground buildings, only the leaves trembled slightly.

After a few minutes, even this slight trembling stopped.The earth is still, and the dirt buries all the dirty secrets, as if nothing has ever happened.

Ji Fan raised his head and saw a bright sun rising from the treetops.

Another new day.

Fu Mingyuan stretched out his arms from behind and embraced him. This warm embrace seemed to give him some kind of courage. He turned around and hugged the other person's neck.

This secret hug did not attract much attention, because almost everyone present was hugging, silently celebrating the rest of the life after the catastrophe.

As the sun rises, smoke rises from the villages at the foot of the mountain, and the singing of birds is melodious and crisp.

The brief warmth was over, Xun Jiangyun cleared his throat, and said: "It's getting late, those who are leaving, come and prepare?"

Everyone looked at each other—finally, it was time to say goodbye.Chen Zhen pushed aside the bushes and walked forward, only to see behind Xun Jiangyun, the young Ji Fan was already waiting by the camphor tree.

"Lan Zhou?" Xun Jiangyun looked at him in surprise, "You want to go too?"

Chen Zhen glanced at him, but didn't answer.

"Old Yu, even if the technology improves, the risk is still quite high. If you don't do it well, you will lose an arm and a leg like me, even if you die—"

"When did you get so wordy?" Chen Zhen asked impatiently.

Xun Jiangyun choked for a moment, and after a while, he asked cautiously: "It's been so many years, has your mind still not changed?"

Chen Zhen didn't bother to pay attention to him at all, and stood beside the young man with folded arms. "Ji Fan" was carrying heavy documents on his back, and when he saw him coming, he showed a relaxed smile.

"Are you nervous?" Seeing that Chen Zhen didn't answer, he continued on his own, "I'm actually a little motion sick. I suggest you stand behind me later." After speaking, he made a vomiting posture.

Chen Zhen: "..." The Ji Fan he knew was a little angel, how could he mutate into such a vile and evil creature in front of him!

Knowing that the other party was teasing him, he still moved out and sat cross-legged on the spot.

Xun Jiangyun lowered his head to inspect the equipment, and said, "Okay, the departure time is preset at 8 o'clock, and there are two hours left, you can arrange it yourself."

"Ji Fan" shrugged, turned around without hesitation, strolled to the side to find "myself" to play.

——Maybe it’s very interesting to tease little Ji Fan.Chen Zhen suddenly understood what this guy was thinking.

He withdrew his gaze and said to Xun Jiangyun, "What about you?"

"what?"

"I asked you what you plan to do in the future?"

Xun Jiangyun paused for a moment, and said, "I was wondering if I should say goodbye to Li..."

"Tsk, it should have been said a long time ago," Chen Zhen said disdainfully, "It's no reason to let others wait so long!"

Xun Jiangyun waved his hands again and again: "No, I don't want to drag her down."

"Did she personally say that you are a burden? Tsk, Xiao Xun, you are really indecisive."

Xun Jiangyun didn't refute, but Xun Huang who was standing next to him gave Chen Zhen a hard look, and quickly stepped forward to take the wheelchair.

"Come on, grandpa, let's go down the mountain!"

This pair of grandparents and grandchildren with a ridiculous age difference supported each other and walked slowly down the mountain.

"Do you think he will confess to her?"

Chen Zhen turned his head, and at some point Ji Fan stood beside him, alone.He looked back subconsciously, and he did not follow Fu Mingyuan.

"Perhaps... how about your family?"

Ji Fan shook his head: "The two of them pushed me away and said they wanted to talk alone for a while." He smoothed the slightly wet turf with his feet, and said carefully, "Can I sit down?"

"Whatever."

So he sat down next to Chen Zhen.Chen Zhen's body temperature is low, her body under the T-shirt is thin and thin, and her underwear is very rough. It seems that she hasn't taken care of herself for a long time.

"Do you usually live alone now?"

"Well, rented."

"Then... where are the parents?"

"It's been 20 years, even if my parents are still alive, they must think I'm dead, why bother?" Chen Zhen paused, and said softly, "I'm sorry, it's not against you, I didn't kiss them in the first place. "

"Oh."

"Actually... when I was in middle school, I went to your house for every meal. Your grandma is very good at cooking. She knew that I came to eat. In the summer, she went to the vegetable market to buy fresh pork and fried pork..." Chen Zhen pursed her lips, unable to speak.

After a long time, he turned to Ji Fan: "Apologize to your mother for me if you have the chance, I'm sorry about Youzhen."

Ji Fan stubbornly shook his head: "One size fits one size, I can't blame you for that."

Chen Zhen was helpless, as if he wanted to smile, and finally sighed: "Okay, thank you."

The two sat side by side on the grass slope, silent for a while.

Ji Fan hesitated for a moment, then said hesitantly: "By the way, I came to ask you. I didn't immediately agree to Mr. Xun's request to me just now. I... I did this, yes, isn't it... a bit too much." Are you selfish?" Before he finished speaking, his face was already flushed, and he curled up in shame.

Chen Zhen said confidently: "What's wrong, he was responsible for the whole thing in the first place, and he still has the face to blame you?"

Ji Fan: "..."

He said weakly, "I didn't mean that either..."

Chen Zhen said: "Who in this world doesn't want to live a good life? The fate of one person is no less contemptible than the lives of fifty people. If you sacrifice voluntarily, ok, that's your nobleness, but forcing people to be noble is shameless."

"It's like people with ulterior motives starting a war. These behind-the-scenes instigators, those with vested interests, will never let their children go to the front line." He sneered, "Of course not, because there must be countless low-level civilians, Blindly believed in the 'justice' they preached, and rushed forward to fill cannon fodder."

"So, before you make any decision, in addition to considering the interests of others, you should also think about your relatives and friends, and the people you love. Finally, ask yourself, is it really worth it?"

"You see, many busy people in this world always think a lot about others and little about family—caring about the eyes of neighbors, the opinions of relatives, and the opinions of colleagues, but why don't they look back at their closest relatives? What about people? Just because he is 'one of his own', can he be sacrificed by default?"

Chen Zhen finished speaking in one breath, slowed down, and calmed down again: "Of course, I'm not saying this to teach you to be a selfish person. I just hope that before you make a decision, you can understand it more clearly. The consequences. On this basis, it is your personal choice."

"—Choice cannot be based on impulse, but on responsibility, understand?"

Ji Fan listened silently.He could probably understand what Chen Zhen meant—he and his lover had experienced the exclusion and discrimination of that era, so it was understandable that his ideas were a little extreme.And when you think about it, these words are not entirely unreasonable.

"I'll think about it carefully, thank you."

Chen Zhen nodded: "That's good."

Another awkward silence.

Ji Fan rubbed his nose: "That... is leaving, don't you plan to say goodbye to everyone?"

"Why goodbye?" Chen Zhen was puzzled, "If you don't make any mistakes, you will meet me again soon."

Ji Fan: "?"

"Oh yes, remember to call me Professor Yu the next time we meet."

Ji Fan: "..." Fuck, he actually forgot about this—Chen Zhen was the leader of the interdisciplinary project team of T University 20 years ago, spanning the two major fields of biophysics. Did you immediately turn back to your elders?

Chen Zhen rarely smiled, and made a joke: "Student Ji, if you dare to skip my basic class, you will die."

Ji Fan: "..." Just put your nose on your face!

The familiar sound of rolling wheels came from the ramp, and Xun Jiangyun returned to the backyard of the hotel alone. On the other side, the mysterious conversation between Fu Mingyuan and the "youth" also came to an end.

Ji Fan patted his butt and stood up, his watch was pointing to 8 o'clock.

Chen Zhen greeted Xun Jiangyun head-on: "Is it all finished?"

Xun Jiangyun said: "No, I let Ah Huang in alone. I didn't talk to her."

Chen Zhen: "..." He showed a look of hatred in his eyes, and said, "Then what should we do now? Are you going to jump with us? With your body?"

"How is it possible? With my current physical fitness, I can't even survive the first round of acceleration," Xun Jiangyun smiled kindly, "I plan to stay for this time, but after I send you off, I may also go to relax —Walking around, I probably won’t go back to Xiaotangshan again.”

Ji Fan was still puzzled: "Why don't you see her? You've been waiting for her for so many years, haven't you?"

"But we're both at this age, so what's the difference between seeing her and not seeing her? I really miss her, as long as I see her live well, I'm satisfied. As for the rest..." He stroked his empty trousers, "Oh , if it wasn't for... that's all, there are so many 'ifs' in the world."

While talking, Xun Jiangyun kept moving his hands and opened the entire instrument box.What Ji Fan didn't expect was that the shuttle, which appeared to be no bigger than a courier box on the surface, was actually covered with a small grassy slope after unfolding.

The bud-shaped reactor rose slowly from the center, and Xun Jiangyun poured the crystals in gloves, then retreated to the side and began to operate the master control computer.After a while, the cyclotron began to operate, and the molten crystals continued to accelerate along the surrounding rings.

The temperature is rising, and the sunlight is shining on the transistors, refracting a charming amber luster.

Ji Fan blinked unconsciously, only feeling dazzled - the light was as deep as a whirlpool, as if he could glimpse a certain rhythm of time from it.

At this moment, Xun Jiangyun turned his head and raised his voice: "It's almost there, come on."

The two stepped forward.Xun Jiangyun checked the time point one last time - Chen Zhen is going back to the past, and "Ji Fan" is going to the future.

This is destined to be a dangerous trip, but the strange thing is that the expressions of the two travelers are very relaxed.On one side, Chen Zhen stared intently at the ground with a blank expression, as if he was counting the leaves of grass.Beside him, "Ji Fan" tilted his head, looking at his other self standing side by side with Fu Mingyuan.

"..." The young man opened his mouth and said a few words.

There was too much noise around, Ji Fan couldn't hear clearly, he took a step forward subconsciously, but was pulled back by Fu Mingyuan by the collar.

"Hey, what did you just say?"

The young man remained silent, looking back at him quietly, and then smiled——Ji Fan rarely saw him smile. At this moment, the young man's smile was very gentle, soft, and even a little innocent.

His light-colored eyeballs were illuminated almost transparent by the growing white light, and the peach-blossom eyes were slightly curved, like a soft firefly.

In the next second, white light exploded.

Several people around were forced to take a few steps back, and Xun Jiangyun, who was closest, couldn't dodge in time, and was thrown off the wheelchair abruptly.

Ji Fan covered the strong light with his backhand, as if being hit by a gun head-on, leaving only a large area of ​​darkness in front of his eyes, and his ears were buzzing.It wasn't until half a minute later that the blurred vision gradually recovered.

Through the flying Venus, he could vaguely distinguish the grass where the two had stood before.

——It’s gone, there’s nothing left.The high temperature burned the turf in an instant, and the only thing left was the cold and hard experimental machinery.

They have left.
