One day in the future, two retired scientists named Dc.Z and Dc.L have nothing to do, and make a bet that the two are geeks in the scientific world, with some unusual research directions and research results, and they have made many amazing things in their retirement life.

......

Jiang Nan has graduated from college for five, six, seven or eight years, and now he is also the project director of the company, and he is starting to urge marriage at home when he is old, in fact, his conditions are very good, he has an economic foundation, and he looks good, but he has not met the right person yet. has been searching, in fact, he talked about a few girlfriends in college before, but then they all broke up, and they didn't talk formally after graduation, some ambiguity, and some physical contact, but there is no proper process of getting along, it seems to be playing adult games, maybe someone was sincere to him, but he didn't have feelings.

......

Recently, a colleague got married, Jiang Nan became the best man as promised, in fact, he has been the best man many times, he has participated in a lot of weddings, only feels a little tired, what else is lively, warm, moving, there are also there, but more tired, but he thinks that for the future, it is worth being tired once.

My colleague is a young man, three, four or five years younger than him, and a couple of newcomers look quite a good match. After attending the wedding, Jiang Nan dragged his tired body back to the house he rented, he hadn't bought a house yet, he had saved enough savings, but he wanted her to be the one in the future. The house was cleaned up very neatly, Jiangnan was a little uncomfortable because he drank too much wine, but no one even poured a cup of hot water, and then the wine, the more he thought about it, the more he thought about it, the more uncomfortable he became, and he was aggrieved and suffered on the sofa for a night.

When I woke up the next day, it was another sunny day, Jiangnan had forgotten yesterday's mood and drunken thoughts, maybe those were buried in the bottom of the heart, not reachable, and the sun could not shine in, only in that drunk or insanity can only show a different sadness, grief, expectation, helplessness, and even desolation.

......

Jiang Nan finally met the person he liked, for him she was a 100% girl, he liked her at first sight, she was a newcomer who had just entered the company, she was beautiful but not charming, a little capable, especially her attitude towards Jiang Nan, which made Jiang Nan's heart itch, and she guessed from time to time whether she also liked herself.

Jiangnan fell in love like this, but he was only one-sided lovesickness, and finally he couldn't suppress the seed in his heart, he launched a pursuit to the new female employee, which is also the whole company is helping, for a while the company gossip is about them, the girl did not act very shy, she accepted Jiangnan's pursuit, the two get along so happily, occasional small quarrels, from time to time you and me, snuggle up to each other, Jiangnan suddenly felt that he had lived in vain before, this is called life.

The two got along for about half a year, lived together, the girl also met Jiangnan's parents, the living habits are very compatible, there is no friction in life, Jiangnan likes her, likes her all the time, he can't wait to bring all the good things to her, make her laugh, make her happy.

Marriage, a major event in life, Jiangnan wants to see the woman's parents, but the girl doesn't seem to have thought about it at all, Jiangnan is a little strange, and many times of communication with her have not been effective, the girl always says it and forgets, he feels as if he is being teased, but when he wants to get angry after many times, the girl promised him to see her parents.

......

At a high-end restaurant, Gangnam meets the so-called "parents" of the girl, two old men with gray hair, who were introduced at the beginning of DC.Z and DC.L. Jiang Nan listened to the jokes of the two people and felt that the whole world was fooling him, he would definitely be ridiculed, lose face, or he would never be able to stay in the company any longer, he fell in love with a robot and had a relationship with "her", he liked "her" so much , but now it has become a joke, a big joke, he can't imagine it, he can't maintain his original gentlemanly demeanor, he wants to take revenge on the two old men, they hurt himself and lose face, but what can he do, the law does not allow him to do what he wants, such as killing two old immortal things!

What the two old men said next interrupted his thoughts. "You love her, you are together your mood is so good, you will feel that your life has become colorful, but just because she is a robot, she can't be your wife, that can only mean that you don't love her enough, she is very powerful, she can get pregnant like a normal person, of course, the eggs provided are selected from the high-quality egg bank, she can complete the life of most ordinary people, she will accompany you to grow old slowly, until she accompanies you to complete the journey, of course, she can still accompany you at the moment of death, what's wrong？”

......

In the end, the wedding was held as scheduled, he loved her, and she loved him with all her heart, and the two became the envy of the people in the company, and they were together for a hundred years.

Soon after the marriage, Jiang Nan asked the girl's consent to tell her parents about it, they were not as surprised as they imagined, Jiang Nan's mother told him: "Your father too, I also met him by chance, and then I was crazy infatuated with him, until I found out his true identity, but I still chose him in the end, now my choice is right, we live very well, but this is also our secret, now it is our family's secret." ”

......

As for what the two old professors were betting on? They bet on whether Jiang Nan would be able to accept that the person he loved was a robot like his mother! The answer was obvious, he loved her, whether she was a human or a technological product, and for him, as long as she was enough.
