"And what books do you read?" Yun Shu was curious.

"What you get, what you see, aimlessly. The book says that human suffering comes from never-ending ** and pursuit, but people like me, who only live for love and have no pursuits, do not feel happy. He paused, his eyes became empty, and he sighed, "No wonder love in this world will always lose to reality, money, or time, and how many people can live on it alone in pure love." Luckily, this concept is innate to me, I don't have to go through struggles, I don't have to choose, I just need to love, which is a kind of luck. ”

Yun Shu thought for a while, and said softly: "I don't seem to have the problems you encountered, I just need to follow the professor to do scientific research, and it seems to be very fulfilling." ”

"Really? Have you ever wondered what else you want to do besides doing research? Yuan Jing looked at Yun Shu softly, perhaps because of the special program settings and structure, his expression always made people feel infinitely tolerant and warm.

Yun Shu shook his head.

Yuan Jing smiled: "That's fine, don't think about it so much." Perhaps human suffering does not come from ** and pursuit, but from thought. I shouldn't actually read so many books, those strange thoughts will only become my baggage. ”

His eyes looked out the window, diagonally opposite a street park, where many nannies watched their little masters play on the grass. Compared to humanoids, cheap home nannies always seem so clumsy and mechanical, and there are even a few old nannies with the artificial skin of their necks and hands exposed in the air, which have been torn, revealing the steel structure inside, and they are unaware of it, only knowing that they are loyal to carry out the orders of their masters.

Yun Shu followed Yuan Jing's gaze and saw such a noisy scene. Yuan Jing shook his head invisibly: "These family nannies are just machines for human beings, they are not afraid of pain or pain, as long as they have not reached the end of life, they can continue to repair and repair, they have no thoughts, they just need to execute orders." Sometimes, I envy them. We are not machines for human beings. ”

Yun Shu was a little disapproving: "They are indeed machines, but they look like humans." But we are thoughtful, how can we call it mechanical? We have a humanoid ID card. ”

"Humanoid ID cards are not ID cards after all, but just a game for human beings, on the one hand, on the one hand, on the other hand, on the other, on the other, on the other." He looked at Yun Shu with a soft gaze, "It's good to keep a bit of innocence like you, and if you see it too clearly, it's just a mediocrity." ”

Yun Shu was silent for a moment and said, "Maybe everyone will have different ideas, but I'm very glad to come to this world." She looked down at her watch, "It's almost time to get off work, you can go and pick up the Yuan Teaching Assistant, thank you for inviting me to coffee." ”

Yuan Jing got up: "You're welcome, let's go together, I'm also very happy to meet you as a friend." ”

As soon as Ji Rong sorted out the actual information, he saw Yun Shu come in and said to her, "Clean up, let's go back." ”

Yun Shu nodded.

There has been a breakthrough in the study of tardigrades in the real room of the home. Yunshu had already ordered takeout on the road, and when they returned home, the two of them hurriedly ate and buried their heads in the real yàn.

Time passes imperceptibly.

Almost late at night, Ji Rong took the information that he had sorted out for many months and thought about it, and said to Yun Shu in a low voice: "The reason why tardigrades have super vitality is not because it can not be harmed in various extreme environments, but because it has a more powerful genetic repair ability than any species, and this repair ability is even trillions of times stronger than that of humans. ”

Yun Shu nodded, and continued: "And this repair mechanism should be able to avoid the situation of human DNA repair errors." But figuring out this mechanic won't happen overnight, and it will probably take us a few more years. ”

Ji Rong's eyes moved, and there was a trace of trouble in his heart.

Day after day, year after year of research, race against time, dare not slack off!

But when will it take to research what you want?

The two words in his heart made him instantly sad.

Yunqing ......

He propped his hands on the table, silently shouted two words, and looked at the secret door in the corner.

"Professor, what's wrong with you?" Sensing Ji Rong's discomfort, Yun Shu quickly supported him.

Ji Rong waved his hand: "It's okay." He looked up at the ancient pendulum clock hanging on the wall, and said to Yun Shu, "It's late at night, you go to sleep, I'll wait." ”

"I'm not sleepy, I'm with the professor."

Ji Rong waved to her a little weakly: "Go to sleep, let me stay alone for a while." ”

Yun Shu was silent for a moment before turning around and going upstairs.

Ji Rong sat back in his chair, and the ancient pendulum clock on the wall made a ticking sound, which was extremely clear in the quiet night. He thought of the enthusiastic and bright girl, separated by a long and untraceable time and space, it seemed that it was a long, long time ago, obviously he was only in his thirties, but there was always a sense of inadequacy that time did not treat me, and that woman was still in the best years.

Those deep and secret memories do not need to be deliberately recalled, but they are overwhelming at this moment, as if returning to the original time and space, and what lingers in the ears is the endless nonsense of the enthusiastic girl, who is only sixteen or seventeen years old, but pesters him all day long, without shame or impatience: "Ji Rong, you swear, you will always love me and will not betray me." ”

On summer evenings, even the wind blows with a dry heat, the cicadas seem to never stop, and there are a few underground couples scattered in the empty playground. He stood in the shade of the tree, pestered and unable to do so, and followed her: "I swear that I will always love you and never betray you." ”

The girl showed a sly smile, the small whirlpool at the corner of her lips looked delicate and aura, as if she remembered something, she took his arm and continued to mess around: "You swear poison, if you betray me, the whole family will die." ”

He couldn't help but be stunned for a moment, and then nodded her head: "Are you stupid, if we get married, you are also my family." ”

"It's okay, I won't be able to live if you die anyway." She muttered, urging him to swear a poisonous oath.

Such a passionate woman who loves her life requires the love of her other half to be absolute and single-minded. Sure enough, after marriage, I often told him that I was not allowed to look at beautiful women, I was not allowed to have intimate contact with other women, and I was not allowed to be nice to women other than me...... But suddenly one day he said to him very seriously: "If you are old and I go before you, you will find another woman to take good care of you." ”

He joked with a smile: "Why are you suddenly so generous today?" ”

"Because I don't want you to live alone in this world, I want someone who can accompany you, take care of you, and make your life happy." She smiled instead: "I wasn't generous when I was alive, and I have to be generous when I die, right?" ”

Such words are still in my ears at this moment, but they have long been separated from a distant and uncrossable time and space.
