law of courtship

Another week passed, and Song sent Zhilan back to the research institute for a comprehensive physical examination as agreed.

From Wuyue Manor to Bazhousuo, the same deciduous path, the same distance and route, Song still carried his beloved little pet on his back, and protected the little thing's face with a hood to prevent him from being blown by a little cold wind .

Last time, what Song thought in his mind was to send him back and return the sick bird to the research institute.

This time, Song's mentality changed completely, he just took Zhilan out of the house, and he must take him home when he was done.

Because the little things belong to his family.

"Uncle, will you still draw blood today?" Zhi Lan pouted a small mouth from the hood, and whispered against Alpha's ear.

"Don't be afraid, it's just a simple inspection." Song hugged his legs tightly, greeted the guard of the institute, and walked straight to the main building.

"Then can they find out what I will be differentiated into?"

"Maybe," Song raised the corners of his lips, maybe it would be a sweet and alluring omega.

According to the patient observation these days, Song has noticed every subtle change in Zhilan, the body hair has not grown, the arms and calves are still smooth, the muscles have not developed signs, and the limbs are still so slender.

As for the secondary development of certain organs, Song really didn't have the opportunity to observe. For some unknown reason, Zhi Lan was particularly vigilant in this regard.

When they wake up in the morning, they occasionally wash up in the bathroom of the master bedroom at the same time. Song often pushes the door in when Zhilan turns on the water. He obviously does it deliberately, but pretends to be unintentional. He just wants to see if the little bird has grown up a bit. .

But Zhilan seemed to have eyes behind his back, as soon as the door moved, he would immediately put away the little bird and put on his pants. Song searched several times with ulterior motives, but found no results.

What the little bird looks like is still a mystery.

The real reason is that only Zhilan knows best: After seeing the big eggplant, he doesn't want to expose his little carrot head, it's shameful.

Song gradually gave up this kind of perverted spying, but all the signs within the scope of observation indicated that Zhilan would most likely be an omega.

Song still clearly remembers Dr. Yu's words: His glands were born because of you, and they will naturally differentiate into omega that is highly compatible with you, like a tailor-made.

As long as Zhilan differentiates into an omega, can he escape the fate of becoming a reproductive tool?

Song was full of joy, a corner of this scratch-off had been exposed, allowing him to glimpse a beautiful rose petal.

Song thought that he might have won the grand prize.

After receiving the news, Dr. Yu waited for them at the gate of the main building of the research institute as usual, and when he saw the tall figure, he walked quickly to greet them.

"Xiaolan, are you feeling okay?" Dr. Yu walked around behind Song and poked the little bump covered in the hood.

Zhi Lan showed his face and smiled sweetly at him: "Good morning, Grandpa Yu, I have always been fine, and I have grown so much taller."

Zhi Lan showed him with his thumb and index finger, about four or five centimeters, and he would draw a line on the bedroom door every day to record.

A growing teenager is like a wheat seedling in early summer, every cell is full of vitality, as long as it is given sufficient sunlight and nutrients, and carefully watered, it will grow differently every day.

Dr. Yu nodded in relief, and thanked the great hero Song Boss: "It's been hard work, you have taken so much trouble these days."

Song gave him a strange look, but didn't answer.

I will raise a wife for myself, how can you thank me for being an outsider?

Dr. Yu led them to the previous floor, and used alcohol spray to briefly disinfect the soles and palms of Zhilan's shoes, and instructed: "Today's examination time is a bit long, so you have to listen to the doctor."

"Okay," Zhi Lan obediently responded, and looked at Song again: "Uncle, will you wait for me here?"

Song rubbed the top of his hair: "Well, go, after the inspection, you have to go home and take online classes."

After Zhilan was taken away by the medical staff, Song felt uncomfortable, subconsciously touched his trouser pocket, "Go to your office and wait, I will smoke a cigarette."

After waiting for a long time, Dr. Yu made a pot of tea to entertain Song: "Has there been any obvious changes recently?"

Song understood what he meant, pretended to be calm and said: "Fortunately, everything is as usual."

"Is there no sign?" Dr. Yu obviously didn't believe it.

"I can eat and sleep, I have grown a lot taller, and I have a good weight."

Song was smoking a cigarette, deliberately avoiding key issues, but in fact, there was pride hidden in the corners of his eyes and brows, like a big dog with a bone in its mouth, hiding food in its mouth and unwilling to be seen by others.

Dr. Yu knew that he was playing tricks, and he couldn't be in a hurry, so he could only comfort himself: "It's okay...the test results will be out in a while."

After a cigarette was burned out, Song put out the cigarette butt with a calm expression, and then picked up the teacup to rinse his mouth: "Have you contacted Huaxia Office yet?"

Dr. Yu rubbed his brows and said in a deep voice: "I contacted you very early, and there were seven or eight teleconferences. Several core researchers from the Huaxia Institute planned to come over to monitor Xiaolan's status in person, so I stopped them because I had to say something. "

Song was stunned for a moment: "So troublesome?"

Dr. Yu sighed: "What do you think? Xiaolan is a treasure over there, and it's not a bag of cabbage, which can be planted in our field and left alone."

Song frowned: "What's their opinion?"

Dr. Yu clasped his fingers and said solemnly: "Whether it is a major accident or a major contribution cannot be defined at present, we just wait for the inspection results to come out."

"Major accident?" Song's hand fiddled with the lighter suddenly froze.

Dr. Yu: "That's right, you've made a mistake in raising him, you and us are inseparable."

Song choked, he remembered that Zhilan said that he was an alpha in nine out of ten chances, and so far, there was no sign of an alpha on Little Things.

The quasi-little a turned into a quasi-little o, which is indeed crooked.

Dr. Yu pinched his brows and said slowly: "Xiao Lan has absolute reproductive isolation from you. If he is an omega, his glands can only receive your pheromones, but he cannot conceive offspring with you, which is equivalent to completely depriving him of fertility..."

"Zilan, the only one in the world who has the second reproductive period, lost one in this way. What compensation do we have?"

"Reproductive isolation?" Song captured the key information in Dr. Yu's words.

"You are an owl, and he is a parrot. This kind of reproductive isolation is obvious." Dr. Yu shook his head helplessly, then turned around and took out an inspection report from the filing cabinet.

"After you took him away that day, I used the reserved samples of both of you to do gene comparison and chromosome test."

Dr. Yu spread out the report, and each page was full of complicated forms and graphs, and the letters on them were all familiar, but just put together, they became a heavenly book.

"Zi Lan's chromosome number is 64, and your chromosome number is 62. And there are 18 pairs of telocentric chromosomes in Xiaolan's chromosomes, and yours only has 11 pairs."

"That is to say, when the reproductive cells combine, your chromosomes cannot be paired normally, or the synapsis is disordered, and it is impossible to complete meiosis and form normal gametes..."

Song looked confused, Dr. Yu had no choice but to ignore all the verification theories, and told him the result directly: "So, according to the conventional way, it is impossible for the two of you to have offspring."

It was difficult for Song to digest the information for a while, "You two can't have offspring" echoed in his mind, and Zhilan's disappointed and wronged eyes suddenly appeared in front of his eyes.

Song doesn't care about having offspring at all. He once thought that he would die alone, but by chance, he has the most precious treasure in the world, a beautiful blue chick.

Song had also envisioned their future, he was willing to always regard Zhilan as his baby and also his closest lover, to raise him, teach him, possess him, love him, this is not contradictory.

Ke Zhilan likes eggs, very much.

He loves all round white objects, and even loves eggs.

More than once, Song has seen the little thing use the round down pillow as an egg to hatch under his body, and he will hold it at night, even in his dreams, he will guard his "egg".

That pillow seems to have become Zhilan's... spiritual sustenance.

Zhilan is a little bird that really wants to lay eggs. Song knows this very well, and is willing to fulfill this wish with him, stepping on their backs and mating in their nest, so that the little blue bird can lay a nest of lovely eggs.

Song never thought that such a small wish would be completely shattered.

The two of them can't have their own eggs, will Zhilan be... very sad when he finds out?

Song forced himself to calm down, and said calmly: "You just said that there is no way to conceive through the conventional way. I want to know, are there any other options besides the conventional way?"

Dr. Yu breathed a sigh of relief, but his tone was not relaxed: "Of course."

Song's fingertips trembled, he lit a cigarette first, and took a deep breath: "Say it."

Dr. Yu's eyes flickered: "Scientific methods can break reproductive isolation. This technology has already appeared. The most common methods are somatic cell fusion and genetic engineering breeding."

"So?" Song knew that Dr. Yu hadn't finished speaking, otherwise he wouldn't be so nervous.

"...But these two technologies are only used in the breeding of crops and livestock varieties, and the preparation of monoclonal antibodies. So far, they have not been used in the reproductive link of humans or humanoids. You should understand that they violate the ethics."

"Can you explain it to me?" The acrid smoke was inhaled into the heart and lungs, but Song calmed down and listened obediently.

Dr. Yu paused for a moment, and chose the most easy-to-understand method:

"For example, tomatoes and deep-sea fish are not only reproductively isolated, they are even drawn at both ends of the boundary between animals and plants, but scientists can transfer the cold-resistant genes of deep-sea fish into the gene chain of tomatoes, and the newly produced species, from In a strict biological definition, it can be counted as the offspring of tomatoes and deep-sea fish."

"Connect a certain genetic fragment in the dna of one organism to the dna chain of another organism, and reorganize the dna to design new genetic material and create new organisms according to the wishes of the original human beings. type, which is completely contrary to the normal way of reproduction in the past."

"In the same way, if we ignore ethics and transfer Zilan's blue hair and nature to other species, we can mass-produce countless 'little blue hairs', do you understand?"

"This won't work," Song responded quickly: "Humanoids are not crops or livestock, and cannot be abused like this."

Dr. Yu smiled bitterly and said, "Native humans also understand this principle, so we haven't done this until now, and Xiaolan and his brother are therefore more precious."

Song frowned: "Is there no way to have both?"

Dr. Yu's expression became more serious: "The other method is closer to natural reproduction, but it also violates ethics."

"This is what I'm most worried about. If the Zilan family really goes to the point of extinction, I'm afraid that Xiaolan will become the first experimental subject."

The author says:

Xiaolan: What about the egg? qaq

Father Song: Good boy, let's hatch the pillow first

Don't worry, the little blue baby will be fine, and the reproductive isolation between the big bird and the little bird will be resolved, believe in science (?˙?˙?)
