Old man Zhang slept until the morning before getting out of bed, the table had been set up early, and He Yanrou also left a note, saying that she promised her younger brothers and sisters to take them out to watch movies and play, so she would not come back at night.

"This kid!" Old Man Zhang touched his forehead, feeling the drunkenness all over his body, and then sighed that he couldn't drink any more.

After a simple shower, Mr. Zhang cleaned himself up, changed into a set of clean and handsome clothes, and then went out.

Today, the old man originally planned to play the game normally, but what happened yesterday has always haunted his heart, and after thinking about it, the old man Zhang still decided to go out and find someone.

Who to look for?

Find your ancestors!

That's right, Old Man Zhang decided to go to his ancestors.

A man can cut off his offspring and have no offspring. But it is absolutely impossible for a person not to have his own ancestors, so even if Mr. Zhang is a Martian 5,000 years later, one of his ancestors must live on the earth at this time.

This is the thought that suddenly arose in Mr. Zhang's heart after feeling his loneliness yesterday, and then this thought could not be dissipated and has been haunting his heart.

Anyone who wants to find their ancestors 5,000 years ago sounds like an extremely incredible thing, and it is simply impossible to do it, and no one can know who their ancestors are for 5,000 years!

But Mr. Zhang is different, Mr. Zhang clearly knows who his ancestors were 5,000 years ago.

After all, all life on Mars is the 72 ancestors of Mars, these 72 ancestors mingled with each other and married, gave birth to offspring, and then the offspring combined with each other, after 5,000 years, finally formed, with hundreds of millions of people on Mars.

If you look at the family tree, you will find that in fact, there is still He Yanrou's blood in Old Man Zhang's body.

However, He Yanrou is not the direct ancestor of Old Man Zhang after all, and Old Man Zhang's ancestor will only be the only ancestor surnamed Zhang among the 72 ancestors, after all, Old Man Zhang's surname is this.

So at this time, as long as you find the only ancestor surnamed Zhang among the 72 ancestors on the earth, you will be able to find the ancestor of Old Man Zhang.

And the life information and records of this old ancestor are all recorded in historical documents, if Old Man Zhang really wants to find her, it is actually a very simple thing.

Well, it's her, that's right, this ancestor is a woman.

It's also very magical, all 72 ancestors have different surnames, and none of the ancestors have the same surname...... Among the 81 ancestors, there are so many people with the same surname, such as the brothers and sisters of the Lian family.

But the miraculous thing is that these people with the same surname have all defected, and these renegade guys naturally have no right to inherit the lineage, and in the end they didn't even leave a single corpse.

Originally, it stands to reason that all children should follow their father's surname, but in this way, the surname of Mars will not be attenuated to only 30 or so, which is not conducive to the development of human beings.

Therefore, Mars specifically stipulates that children born to women can also be named with their own surnames, so that the human surname remains 72, reducing the chance of intermarriage between close relatives in the future.

The human bank spaceship originally carried a huge sperm and egg bank, but in the course of the human civil war, the egg bank was destroyed and all the eggs died.

Therefore, only women can reproduce their offspring alone, using sperm from other sperm banks.

There is no question of whether it is green or not, this is the result of the unanimous agreement of the ancestors, because only in this way can the diversity of human genes be guaranteed, otherwise there will be serious problems in human beings sooner or later.

Therefore, the descendants of Mars can only judge which ancestor is descendant according to their surname, and it is difficult to judge who the other ancestor is, maybe it is just a sperm in the sperm bank.

Old man Zhang's ancestor is like this, since Old Man Zhang's surname is Zhang, he is definitely the descendant of the female ancestor surnamed Zhang, but this old ancestor uses the remaining children of sperm in the sperm bank, so Old Man Zhang can't judge his other ancestor, only knows one.

But one is enough, Mr. Zhang just wants to find his lost family affection, and one is enough.

According to the historical records of Mars, the ancestor of Mr. Zhang is named Zhang Yingyun, he is a doctor, and he is an extremely outstanding doctor, at the age of 30, he independently completed the spinal nerve connection surgery, and successfully reconnected the nerves of the spine part of a paraplegic patient with lower half.

Although the patient could not be allowed to regain normal mobility, the lower half of his body was no longer unconscious.

This gave Zhang Yingyun a huge honor, and he was also selected to enter the Martian astronaut industry, becoming one of the only two doctors in the team.

Zhang Yingyun is in charge of surgery, and another doctor is in charge of internal medicine, thus ensuring the safety of the entire astronaut team.

And this is the ancestor of Old Man Zhang, and what Old Man Zhang is looking for is her.

Dr. Zhang Yingyun is not from the magic capital, but from Wuxi near the magic capital, so Mr. Zhang has to drive to the first hospital in Wuxi to meet his ancestors.

Old Man Zhang made up his mind, just glanced at it from a distance, looked at the voice and smile of his ancestor, and then turned his head and left, so that he could be regarded as finding a relative for himself and proving that he was no longer alone in this world.

Zhang Yingyun is easy to find, after all, the historical data clearly records that Dr. Zhang Yingyun at this time is already a well-known expert in Wuxi First Hospital, and he should find his ancestors as long as he arrives at Wuxi First Hospital and looks at the hospital's wall of honor.

It's just that when Mr. Zhang entered the hospital with a trace of respect, he found that on the honor wall of the hospital, there was no ancestor of his own at all, there was no name of Zhang Yingyun, no photo of Zhang Yingyun, and there was nothing.

"Hello, may I ask if there is a doctor named Zhang Yingyun here?" When the old man walked to the service desk and asked.

"Doctor Zhang Yingyun?" The nurse at the front desk thought for a long time, "It seems that we don't have a doctor with that name here!" Did I forget? ”

"No, she should be well-known in your hospital now!" Old Man Zhang muttered with some confusion.

"Impossible, if it was a well-known expert doctor, I wouldn't have known it!" The little nurse shook her head, and then shouted at a nurse behind her who had been keeping her head down and recording something, "Yingying, do you remember that there is a doctor named Zhang Yingyun in our hospital?" ”
