When Fang Ziyu came to the first floor, he saw two rare guests.

Two cute little girls, Kiki and Luoluo.

Fang Ziyu came down and the two little girls were teasing a blue and white Ying short in front of the display case, and the cat was the one who had been pushed down from the cat climbing frame by Rhubarb and sulked for a long time.

In the face of the flattery of the two delicate and cute little girls, he finally let go of his reserve, meowed, and became intimate with the two little girls.

Chen Youlan watched from the side to prevent the two little girls from being injured by pets.

"Master, these two little girls are coming to you, saying that they have a question and must ask you. ”

Seeing Fang Ziyu, Chen Youlan explained.

Before Fang Ziyu could speak, two little girls walked up to him with their pets and greeted him crisply: "Brother Ziyu, good afternoon!"

"Hello, have you been having fun going to school lately?" Fang Ziyu asked with a smile.

"It's fun, there are special pet classes, it's much more fun than before. Kiki said with a smile as she pulled Samoyed.

"yes, it's fun, there's a special pet race. Luoluo showed off to Fang Ziyu, and then became a little angry, "It's a pity that my sloth is too lazy, I actually started to sleep lazily while running, I am the penultimate ......"

"Haha, Luoluo can participate in the competition next time."

"Brother Ziyu is not allowed to laugh at me......" Luoluo pouted and looked at Fang Ziyu.

Fang Ziyu sat down on the bench and promised, "Okay, I won't laugh anymore." What about your parents, what are you looking for me?"

"My dad was shopping nearby. Kiki said, tilting her head.

"So did my dad. Luoluo raised his little buttocks and sat opposite Fang Ziyu in a decent manner.

Fang Ziyu: "......"

These two fathers really have big hearts.

"Brother Ziyu, we came here to ask you questions. The two little girls said in unison.

Chen Youlan poured a handful of water and gave it to Fang Ziyu, then sat next to her and listened.

"That's Brother Ziyu, recently there is a pet class task in the school is to hatch a duckling, so that we can understand the process of hatching pets and understand pets better.

We hatched the ducklings in the hatchery room according to the teacher's instructions, but something went wrong.

We learn how to call the duck and pretend to be the mother of the duckling, but I don't know why, sometimes the duck follows us and treats us as mothers, and sometimes they don't go with us, and the cry is very miserable, as if the mother is dead. Brother Ziyu, why do you say?"

The two little girls said a general idea of the matter, and then looked at Fang Ziyu expectantly, asking for an answer,

Fang Ziyu glanced at the two little girls, their big bright eyes full of anticipation.

"This is the homework your teacher gave you, right? Do you want to be lazy?" Fang Ziyu said.

Hearing this, Luoluo's eyes widened and his mouth widened: "Brother...... How did you find out?"

Seeing Luoluo's appearance, Qiqi angrily inserted her waist and said, "Luoluo, how can you admit it directly? Didn't you say okay? You don't keep your promise." ”

Luoluo hurriedly covered his little mouth: "I'm sorry, I forgot ......"

Fang Ziyu smiled and said, "Qiqi, it's not right for you to do this, children can't deceive people." ”

"Do you know that brother Ziyu?" Qiqi pouted and looked at Fang Ziyu, "Brother, you definitely don't know why you said this on purpose." ”

Fang Ziyu smiled: "It's useless for you to provoke the method, I won't tell you the answer."

But I can give you a hint, you can go back and try to summon ducklings in two different positions, squatting and standing, and you'll find out. ”

"Is it?" Kiki was a little incredulous.

"I promise." Fang Ziyu guarantees.

The two little girls were skeptical, but finally nodded: "We'll go back to the experiment." ”

didn't get a direct answer, Qiqi was a little unhappy, took Samoyed and stood up and said, "Brother Ziyu, goodbye, I'm going out to walk the dog." ”

"I'll go too, goodbye Brother Ziyu. Luo Luo jumped off the bench and said.

"Be careful. Fang Ziyu nodded helplessly, lay back on the recliner and said.

The two little girls waved their hands and trotted away, laughing and laughing.

Seeing the two little girls go out, Chen Youlan looked at Fang Ziyu and said, "Master, do you really know? I really don't know this question." ”

"Of course, otherwise you think I lied to two little girls?" Fang Ziyu rolled his eyes while lying on his back on the recliner, "Of course this is true, this has something to do with genes, I don't know why." Just know that this is similar to a rule.

Although newborn ducklings will take the first object they see as their mother. But this is premised on the fact that the object should not be too large.

If a duckling is born with both a human and a dog, you will find that it will not hesitate to treat the dog as its mother, not a human. ”

"Is that so?" Chen Youlan murmured, "I never knew about this kind of thing, and I didn't observe it carefully. ”

"Haha, it's not your fault, I also learned about it because the pet store needed it. It is said that this is because the duckling genetics have an instinctive impression of the mother's body type.

You will find that when you squat and learn to call the ducks, they will follow you, but when you stand up, no matter how similar you learn, the ducklings will not follow you, and they will scream miserably, thinking that their mother is dead. This is because you are too tall to stand up and do not fit the instinctive impression of your mom in your genes.

That's why they don't work well when they are duck mothers, not because they don't learn well, but because they stand up.

There are so many such phenomena in nature, and only naturalists can find them so carefully observed. ”

"So, that's why we had to squat down when we were kids?"

Chen Youlan said.

"Yes, almost, a lot of things are the way they are for a reason, not as simple as they seem, like those old proverbs. ”

Fang Ziyu took a sip of tea and said, he found that his observation seemed to have improved, could it be that this Netherheart Butterfly was parasitic in his mind?

If it had been before, it would have been difficult for him to observe the small movements and slight differences in his eyes when he spoke.

"Master, you're amazing!"

Chen Youlan looked at Fang Ziyu with admiration in his eyes, he found that the master was worthy of being a master, and he was so powerful in all aspects.

"Of course, otherwise how can you be your master?" Fang Ziyu snorted, "No, I'll take you to the wild in two days, how are you prepared?"

"I feel like I'm almost ready. Chen Youlan was a little expectant, she had not been out of the wild since the revival of her aura, and she was very interested in the wild with great changes.

Fang Ziyu was about to speak, and his mobile phone rang, and he saw that it was a message sent by Zhou Ruo: "The plan against the troll infestation is about to start, come to me in a while, and I'll take you over." ”

Finally came, Fang Ziyu said secretly, looked up at Chen Youlan and said, "I'm sorry, master, I have something to do temporarily, and I will have to delay taking you to the wild for a few days." ”

Chen Youlan was a little stunned when she heard this, but quickly nodded and said, "It's okay, I'm not in a hurry, master." ”

"Well, when the stray frog grows up, you can pick one, I really shouldn't talk casually. Fang Ziyu was a little speechless.

"Master, don't ...... like this" Chen Youlan shook her head.

"The stray frog was originally prepared for you, and it must be for you. Fang Ziyu said, "Anyway, thousands of them will definitely not be sold, sooner or later they will be given to you, who made you my apprentice." ”

Hearing this, Chen Youlan showed a lucky smile: "Thank you, master." ”
