"Knock-knock-"

When the big clock in the corner of the wall struck five times, Chen Tiange finally raised his head from the pile of data and equations and glanced at the porthole outside.

Outside the window, the dazzling light of the stars has begun gradually, and the satellite hovering in the "Ark" has bent the edge of a graceful light arc and pulled out a dazzling horizontal line.

Already...... Is another day gone?

He sighed heavily.

In this mysterious and strange galaxy, the cycle of planetary rotation seems to be extraordinarily long, almost twice as long as on Earth.

So, by the standards of this earth, he's been working 48 hours straight.

In the past, this was not a big deal, when he designed the "Ark", his highest work record, but reached five days and five nights without closing his eyes.

Only now......

It's only a short 48 hours......

Do you already feel tired?

Really...... It's still time to be unforgiving.

Chen Tiange smiled self-deprecatingly, while slowly standing up from the chair, wanting to stretch his waist to relieve his waist that had become stiff due to continuous overtime, but he was suddenly dizzy and almost fell to the ground.

Oops, awful!

How could it be......

The pain from the limbs was like peeling the skin and cramping, Chen Tiange never thought that the grinding problem would come out at this time!

Chen Tiange involuntarily began to tap the ground with his forehead, trying to divert his attention from the pain of bone contusion all over his body.

But it didn't work...... The pain that soaked into the bone marrow, even if it had broken the forehead horns, showed no signs of being transferred.

How, what to do?

That's right!

And medicine!

He trembled and stretched out his hand to take out the medicine bottle from the pocket of his jacket, but his whole body seemed to be drained of strength in an instant, and even such a simple action almost became an unattainable fantasy.

However, with amazing perseverance, he eventually did it.

Merely......

The liquid that was broken down through the esophagus and stomach and intestines to the whole body did not work as quickly as it should.

The nerve cells that were gradually paralyzed by excessive pain were only slightly relieved, and the symptoms of cold hands and feet and weakness of the whole body were not recovered at all.

How...... Will it be?

Chen Tiange couldn't figure it out, although he was not a doctor, but he had been a doctor for a long time, and he still knew a lot about his old problem.

But today......

Don't......

He pulled out the vial again and scrambled it into his mouth......

In the end, after drinking the third dose of this fast-acting medicine, Chen Tiange could finally lean against the corner, gasping for breath, and showing a wry smile that was too subtle.

It seems that this is really the case......

This problem will occur more and more frequently and more intensely.

So......

I'm afraid I'm running out of time......

Thinking of this, the designer of the spaceship, the chief scientist of the "Ark", looked out of the porthole, and there was a little more indescribable and unclear meaning.

How good the stars are, they can exist for billions, tens of billions of years, if only human beings could be like them.

But human beings are only human beings after all, and their short lives are nothing more than fleeting meteors in the universe compared to these planets......

But it's not a big deal - because meteors are short, they always light up the sky with themselves, don't they?

Looking back on his life, he designed an unprecedented spaceship that allowed mankind to get out of the solar system; changed Einstein's law of physics that "no object can exceed the speed of light"; Perfecting the theory of spatial folding; The technology of curvature navigation was devised and eventually used to save the last civilization of mankind......

No matter how you look at it, in the field of physics, you have reached unprecedented heights, enough to go down in history without any regrets.

So the only thing that can't be assured is ......

"Let Dr. Chen come to my office."

After recovering his strength a little, Chen Tiange used the walkie-talkie on the desktop to instruct his secretary.

"Okay, Professor." The female secretary replied in her sweet voice as always.

Chen Tiange breathed a sigh of relief gently......

I have to talk to Meng Yao.

Although I still can't let her know about my illness, it's finally time for that matter to be put on the agenda.

Thinking of this, he picked up the phone again:

"Hey, Old Yang?"

————————————

"Dad, are you looking for me?"

Standing in the cabin of the "Ark", which was used as a laboratory, Chen Mengyao looked at her father, who was still turning his back to her and burying her head in writing, and for a moment, she was a little overwhelmed.

"Well, wait a minute, just find a place to sit." Chen Tiange wrote something on the table without raising his head.

However, Chen Mengyao did not listen to her father. A strange feeling, familiar and unfamiliar, once again hit her heart.

Speaking of familiarity, because my father's small cabin, I don't know how many times I have been to it since I entered space: all kinds of messy manuscript paper and sundries; Instruments with flashing colorful indicator lights; The haphazardly connected wires intertwined with each other, silently telling the truth that no one but their owner could discern their purpose; Under the microscope on the tabletop, a glass bottle containing an inexplicable liquid was burning on the alcohol lamp next to it...... In short, everything is no different from what I know.

Speaking of strangeness, it's because it's still a little different after all......

She couldn't say what the difference was, but she had a vague feeling.

Thinking of this, the beautiful female scientist once again hit the man in front of her with a watery eye.

It's been a long, long time since she's looked at her father's back so intently.

Feel my father's back, the back that has always reassured me...... It seems to be a little more rickety......

The gray hair in my ears seems to have added a few more......

Is it because of this that you feel different?

She couldn't say it herself.

In my impression, my father's back is always tall and broad, and my favorite thing when I was a child was to let my father carry me around to play, and when I was tired of playing, I would lie on my father's back to sleep - that would make her feel very comfortable.

When I grew up, whenever I encountered something confused in academics, my father always stood in front of me, guiding her direction with a generous back......

But since going into space, how long has it been since you had a good look at your father's back like this?

Is it your own neglect?

No!

It's all Qin Feng's fault!

Especially during this period of time, he first helped Qin Feng modify the fighter, and then his disobedient head nodded to him so excessively without authorization - improving the weapon system for him, but he didn't even receive a word of thanks!

The most odious thing is that with the "magic weapon" given by himself, this time the military's "Ragnarok", listening to the pilots of the Second Air Force who came back, it seems that he rushed to the front again!

Don't you know the dangers...... Wrong! Don't you know to converge a little?

This Qin Feng is really ......

It's too much!

What's more, in order to design for him, he had promised to help his father share the improvement of the spaceship's power system, but in the end, the process was delayed, and he had to be scolded by his father......

So sure enough, it's his fault!

He must be asked to take all this sin well!

Qin Feng!

“…… Meng Yao, I'm talking to you, didn't you hear? ”

"Huh?"

Chen Mengyao, who was finally raised by her father and pulled out of her thoughts, blushed a little because of her distraction.

"I'm sorry, Dad. I'm thinking...... Thinking about ...... Oh yes! Thinking about antimatter. ”

"Antimatter?" Chen Tiange raised his tone slightly.

"Yes, yes. If you think that the annihilation of antimatter can also produce huge amounts of energy, then if it is applied to the power system...... "Feeling that her father did not seem to accept her words and showed signs of going berserk, the beautiful girl hurriedly tried to explain further, and the result was ......

"Large-scale separation of positive and antimatter in the universe is impossible. Therefore, the absence of antimatter objects within the range of 30 million light-years indicates that there are no large antimatter objects in the universe. This kind of common sense that today's elementary school students know, you actually think about this very seriously?! Are you telling me that I'm not even as good as an elementary school student?! Chen Tiange stroked his forehead with one hand.

"Uh......"

Chen Mengyao choked violently, blushed suddenly, and then quickly changed the topic: "Compare, compared to that...... Dad, what are you looking for me? ”

However, Chen Tiange was silent.

Speaking of this daughter, since she came back from that trip to the desert planet to detect uranium mines, she doesn't know what's going on, the whole thing seems to be a different person, first of all, her brain always seems to be short-circuited, and none of the work assigned to her is satisfactory.

Then when I go home to eat at night, I often feel inexplicably in a daze, suddenly laugh for a while, and then converge, and then frown, and then converge, such as practicing ** gong.

Although compared to three years ago, it was as cold as ice, as if a wall had been built for itself, and no one was kept away, but it was still very gratifying to know that burying one's head in the laboratory had finally changed compared to that situation......

But he didn't expect to become a psychopath.

Alas, it's really not worry-free......

"Huh?" The beautiful girl scientist who was stared at by her father was uncomfortable, and after seriously thinking about what she had missed in the past two days, she finally couldn't help but open her mouth tentatively again, "Dad? ”

"Yaoyao, how old are you this year?" Giving up his plan to continue to be more serious with his daughter, the chief professor of the "Ark" furrowed his brows and asked earnestly.

"2^22, what's wrong?" Chen Mengyao replied a little frightened.

She originally thought that her father should ask her a little question about the improvement of the "Ark" power system, and when she was worried about how to explain it, she didn't expect her father to suddenly ask about this.

And what she didn't expect was that this time it was ......

After all, what's going on with that "Yaoyao"!

That kind of name, she was only called that by her father once before she went to elementary school.

"Is it like this?" Chen Tiange stared at his daughter.

frowned, but tightened.

It's already 23.

The daughter even forgot her age. It seems that what Lao Yang said is really right......

Earlier today, when I vaguely mentioned Chen Mengyao's recent question to my friend, Lao Yang, a scientist in the biology group, the answer I got was......

"Girls have nerves, and eighty percent move mortal hearts!"

That's what Lao Yang said at that time.

So, it seems that the thing ...... It's time to hurry.

"What's wrong? Father. Chen Mengyao looked at her father's poor face, and her heart became more and more worried.

"Nothing." Chen Tiange shook his head, "By the way, what do you think of Yang Xiao?" ”
