Yi Xin heard the knock on the door and ran to open it.

At the door were three little boys, about the same age as Jiao Yuan, all of whom were classmates from elementary school. They often play together. Black carbon knows, but Yi Xin doesn't.

Without waiting for Yi Xin to ask, one of the children said righteously: "Who are you?" The other pulled out a small rolling pin with a mouse's tooth mark from his bag, and was on guard.

Yi Xin looked at the three children who were obviously wary and suspicious, and the smiles on his face froze. It took him five minutes to explain his identity, and he even pulled out his graduate school card to prove his identity.

The three bear children huddled together to study the photo on the ID, "The person in the photo is your brother, right?" It's obviously more vicissitudes than you! The child with the rolling pin said, and after a pause, he suddenly rejoiced: "I actually use the word 'vicissitudes'!" ”

After checking Yi Xin's documents, the bear child returned it to him and walked into the living room.

The three of them saw Black Tan lying on the sofa safely, so they really put their minds at ease, so they sat down on the sofa one by one. And Su Musha let go of the sofa at the first time and moved to the armrest of the sofa on the side of the black charcoal.

Yi Xin looked at the three babies, a cat and a mouse on the sofa, sighed, moved a chair for eating and sitting, and prepared to sit down.

The three bear children looked at Yi Xin who was about to sit down in unison, looking at Yi Xin inexplicably and confused.

Su Musha squatted on the handrail, watching the two groups of people look at each other, not only covering his mouth and snickering. Black Charcoal exhaled a long breath, jumped off the sofa, came to the refrigerator, jumped up and opened the refrigerator.

"Oh~~"

"It's still black charcoal sensible!"

"Hospitality! Eldest brother! ”

Yi Xin: "......" Lao Tzu is also a guest!

The strongest boy scurried over at once, rummaging skillfully.

"Xiong Xiong, I want a mango flavor!"

"I want apple flavor!"

Xiong Xiong rummaged through it with his little fat hand and smoked three popsicles.

The three bear children each took a lollipop and gnawed on it, Yi Xin saw that they didn't mean to speak, so he had to take the initiative to ask: "The three children came over and ...... it."

"My grandfather said there were people here, but Jiao Yuan hadn't been to school for a few days, so he came over to ask!" One of the well-mannered children said.

"Your grandfather ......"

"My grandfather is a blue ferretin." Downstairs, Professor Lan's grandson Lan Tianzhu said.

Yi Xin's "......" smile was even stiffer.

"The Jiao family has something to do, let's leave for a week!"

"That's it!" Xiong Xiong was a little dissatisfied with Yi Xin's explanation, but he couldn't go back eating popsicles like this, and he would definitely have to be trained again if he was caught by his mother.

"You're from the Academy of Biological Sciences, right? I have a question! Xiong Xiong asked Yi Xin, "I heard that if you don't eat breakfast, your body will eat, is it true?" ”

Yi Xin: "......" Nima is so tired......

Lying on the black charcoal of pretending to sleep: "......" bear children are bear children!

The Su curtain on the armrest covered his ears and stood up, a classic paragraph! He immediately jumped to the chair where the snacks were placed, took out a peanut for a while, climbed back into the armrest, and prepared to nibble on the snacks to watch the play.

Yi Xin just finished explaining this question academically and was concluding: "So what you said is incorrect! ”

"I'll just say my mom bluffed me again!" Xiong Xiong shouted angrily.

"You can debate with your mom!" Lan Tianzhu came up with an idea.

"No, you'll be punished for kneeling on the washboard!" Xiong Xiong was depressed.

"What's on the kneeling washboard? I knelt on the keyboard two days ago, and I couldn't get up without kneeling down the space bar. Su An, who was munching on a popsicle, said.

"Why?"

"To test if aqua regia can really dissolve gold, I threw my mother's gold-leaf earrings into it and dissolved."

Yi Xin: "......" this loser child!

Black Carbon: Is it too powerful to say that the power of "......" is passed on as a descendant of the Department of Chemistry?

Su Musha: "......"

Su Musha's thoughts drifted a little, remembering his childhood. Because of his parents' relationship problems, he also wanted to attract his parents' attention for a long time, and he threw the hot water bottle downstairs to listen to the sound, and tore up his parents' books to make paper airplanes.

It's a pity that no matter whether he is in trouble or winning an award, his parents are still more concerned about the emotional disputes between them, and they just beat him up or stuff a little money into his hand and send him away, so he acted even more excessively, and almost got together with the street gangsters. Fortunately, he suddenly woke up when he was in junior high school, otherwise he would have caused more and more trouble, and then he would not have ended well.

Su Musha turned his thoughts back to his eyes, just as Xiong Xiong was proudly showing the red mark on his leg: "This is what I pinched myself in order to cry more seriously!" My mother really relented, and changed the original kneeling for an hour to kneeling for fifteen minutes~"

Yi Xin, Black Carbon: "......" this triumphant fart!

Su Musha: I was so naïve back then!

A topic is over, and the popsicle is not finished yet.

"Oh, this is what Jiao Yuan said about the 'gray ball', right?" The subject was reversed stiffly.

Su Musha was watching the excitement seriously, but he didn't want to be noticed by the three bear children, and suddenly became nervous. For the small body of the weak hamster, the bear child is a creature that needs to be kept away.

The three small surrounded Su Musha to watch strongly.

'Huh?' Gray Ball' doesn't look like a guinea pig in the lab! "This is Lan Tianzhu, who often sneaks into the laboratory of the Academy of Biological Sciences.

"Sure enough! Looks a lot fatter! "This is Xiongxiong who is more interested in eating.

"It's probably not the same species as the guinea pig, I remember seeing it in a book." Su An really got a lot of inheritance...... But the next sentence, "Go back and let Jiao Yuan bring the 'gray ball' to my dad's laboratory to play!" ”

Su Mu covered his whole body, "Help! I don't want to go to the chemistry lab! ”

Su Musha hugged his peanuts, plucked up his courage, and while the three bear children were still watching, he trembled and climbed down the handrail and ran towards the black charcoal.

"Help! Top dog! Your little brother is going to be caught and sliced! ”

The bear child watched the little hamster run away, but he didn't mean to chase and beat him. Just as the popsicle was finished, they reluctantly pulled up their school bags and left.

Before leaving, Xiong Xiong also seriously reminded Hei Tan: "Recently, there have been thieves in the compound, pay attention, many have been stolen." Don't lend your access card or let strangers in! ”

When the three bear children left, one person, one cat and one mouse in the house suddenly felt that the world was finally quiet.

Black Tan has been tossing enough in the past two days, and he remembered that Wei Ling invited him to exercise in the morning, so he went to bed early.

Late at night, Yi Xin finished correcting his thesis and was about to go back to the living room to sleep on the sofa when he passed by Xiaoyuzi's bedroom. Through the light of the living room, I saw a large Garfield doll resting in the middle of the children's bed, and the black cat was lying on it, one leg curled up, and the other leg pressed across Garfield's big cheap face. On a pink pillow at the head of the bed, a light gray hamster was lying in the center with its limbs spread out, and a black hair on its back was lying with its breathing. A cat and a mouse slept soundly......
