Yi Xin trembled and explained his intentions, and Professor Lan "snorted" as soon as he heard that Zheng Si had fleas on his body, "You deserve it!" ”

However, after all, Professor Lan still went to get medicine for Zheng Si, and Zheng Si followed him into the room.

As for Yi Xin, he mops the floor in the living room with a mop.

Professor Lan is a retired employee of the School of Life Sciences of Chuhua University, although he has retired and no longer teaches, he still has a great influence in the School of Biological Sciences, and even if he no longer teaches, some companies hire Mr. Lan to do guidance with high salaries, and Mr. Lan has cooperative relations with many companies. Therefore, don't look at the simple decoration of Old Man Lan's house, and the people are worth a lot of money.

Professor Lan has always had a tense face, giving the impression that his temper is not very good, and he is too serious. From time to time, Professor Lan would go to the School of Biological Sciences, and the old man would supervise the formation during the practical guidance of the botany course, and some young teachers were a little lacking in confidence to speak, let alone those students, who did not dare to come out.

It's no wonder that Yi Xin stuttered when he saw Old Man Lan, he was promoted from this school, and the experience of botany courses back then is still deeply impressive in retrospect. So Yi Xin is very curious, Old Man Lan is not the kind of person who can read people's faces, even if the current Dean of the Academy of Biological Sciences is here, Old Man Lan may not necessarily give face, that is to say, it is definitely not Boss Jiao's reason, but why is Old Man Lan so tolerant of the boss's cat?

Being able to let Old Man Lan treat him like this was actually just something that Zheng Si did by chance. More than a month ago, when Zheng Si went downstairs to walk, he met Mrs. Zhai, the wife of the old man Lan, the old lady's heart was not very good, when the old lady helped an old lady in other buildings to move some heavy objects, and when she came back to go up the stairs, she suddenly showed some signs of illness, and it was the time to go to work and class, and the old man Lan was on a business trip, and the old lady took out the bottle containing the medicine ** tablet when her hand shook, and the medicine bottle rolled down the stairs, and the old lady's state at that time was difficult to move a step. In the end, it was Zheng Si who ran downstairs and brought back the medicine bottle to the old lady.

The old lady took the medicine in time and quickly eased up. Since then, Mrs. Zhai smiled every time she saw Zheng Si, if Mrs. Zhai was at home today, Old Man Lan would definitely not dare to scold Zheng Si, the old man had a big temper externally, but internally, the old man only had to be scolded by the old lady, of course, when there were outsiders, the old lady still gave the old man face.

So Zheng sighed that he had the support of the old lady, and he was not afraid of the tight old face of the old man Lan at all.

Old man Lan took out two bottles, one bottle was liquid and the other bottle was a powdered medicine.

The liquid medicine is for Zheng Si to take a bath, which can avoid getting fleas when he goes out to play, Zheng Si used it before, and after he used it up, he didn't come to Old Man Lan to ask for trouble. As for the bottle of powdered medicine, it was sprinkled on the body. These things are not sold outside, they are all configured by the old man himself, pure natural and safe and guaranteed, even if the cat licks it into its mouth, it is fine, but Zheng Si never licks his own hair, so he doesn't have to worry.

The old man poured out some medicinal powder in the palm of his hand, and then wiped it on Zheng Si's hair.

Zheng Si turned his head to look at the messy hair on his back, and looked at the old man with drooping eyelids. The old man didn't say a word, and only after smearing the powder did he slowly close the bottle cap, slowly put it back into the bottle, and then slowly gave Zheng Si the reversed hair back, and after it was smooth, he slapped it twice, almost patting Zheng Si down.

"If this medicine is sold, you can buy a room of cats, you said that you took such a big advantage, when will you go to the little flower garden to help me?"

Old man Lan didn't expect the cat in front of him to understand, he just made a fuss, and by the way, he slapped Zheng Si a few more times to retaliate.

Zheng Si tugged at his ears, shook his hair, and ignored the old man who was talking to himself there, walked out of the room, and prepared to go back.

Outside, Yi Xin had finished mopping the floor and sat stiffly next to the edge of the sofa, and even a fool could see his nervousness.

Old man Lan handed the two bottles of medicine to Yi Xin, and went back to the room to bring a small brown glass bottle, "Those two bottles are for cats, I don't need to tell you how to use them, you just go and ask your mentor, this brown bottle is an insecticide, 10X concentrated, dilute it yourself when you use it." ”

After speaking, Old Man Lan directly opened the door and motioned for one person and one cat to go out.

"That...... Thank you for the trouble! ”

Yi Xin said thank you stiffly, hugged the bottle in his hand, and followed Zheng Si out the door.

When he returned to Jiao's house on the fifth floor, Yi Xin breathed a sigh of relief.

And Zheng Si is now much more relieved, solving the flea problem, he feels comfortable, and he has nothing to do to tear open a bag of grilled fish fillets and eat it.

However, before this person and a cat could feel too comfortable, the door rang.

Listening to the frequency of tapping on the door and the movement at the door, Zheng Si had already guessed the identity of the visitor, looked up at the ceiling, and let people not be clean!

Yi Xin didn't know who was outside the door until he opened it.

At the door are three little boys, about the same age as Jiao Yuan, all of whom are in the sixth grade at the Primary School Affiliated to Chuhua University, all of whom are in the family compound, and several people often play together. Zheng Si knew them, but Yi Xin didn't.

Without waiting for Yi Xin to ask, a child spoke up: "Who are you?!" ”

That's a righteous word. One of the sturdy children also took out a small rolling pin with a mouse's tooth mark from his school bag, and was on guard.

Looking at the three children who were obviously wary and suspicious, Yi Xin stiffened with a smile on his face that was specially pulled out to show affinity, and it took him five minutes to explain his identity, and even took out his graduate school ID to verify his identity.

The three little kids huddled together and looked at the photo on the graduate student card, and then looked at Yi Xin.

"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'!" ”

"I hope you remember to use it next time you write an essay, maybe you can get more than 90 points." Another child said as he returned Yi Xin's graduate school card.

The three of them walked into the living room and looked at Zheng Si who was lying on the sofa safely, this time they really put their minds at ease, the cat was not abnormal, proving that the person named Yi Xin was really an acquaintance, so they sat down on the sofa one by one.

Yi Xin looked at the sofa that was no longer vacant, and moved a stool from the dining table.

The three little boys sitting on the sofa looked at Yi Xin who was about to sit down, and Yi Xin was inexplicable, as if he had done something angry.

Zheng Si looked at this scene, 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, this eldest brother surnamed Yi, even a cat understands this truth."

Yi Xin, who was criticized: "......" paralyzed me if it were my family, I would also understand, but the problem is that this is Boss Jiao's house, and I eat a bag of snacks carefully! Lao Tzu is also a guest!

The strongest boy was the fastest, and he was in the refrigerator and turned around there.

"Xiong Xiong, I want a mango flavor, last time I saw Jiao Yuan hidden in the innermost, you turn it over!"

"I want apple flavor!"

Yi Xin twitched on his face, is this a devil entering the village?

Xiong Xiong flipped twice in it with his little fat hand and pulled three popsicles out.

Looking at the three children sitting on the sofa munching on the popsicle, Yi Xin asked, "Three children come over and ...... this"

"My grandfather said that there are people here, and we saw that Jiao Yuan hadn't been to school for a few days, so we came over to ask." The kid who blamed Yi Xin for not knowing how to be hospitable said.

"Uh, who is your grandfather?"

"My grandfather is a blue ferretin."

Yi Xin: "......" smile is a little untenable.

Lan Tie is the name of the old man Lan.

These three children, one is Lan Tianzhu, the grandson of Old Man Lan, the other is the child of a teacher in the College of Chemistry named Su An, and the last sturdy one is called Xiong Xiong, Zheng Si doesn't know the detailed identity, I only heard that his family has a bit of a background and is very familiar with the principal.

Yi Xin knew that his boss had something to do to go to the province, but he didn't know what it was, so when he explained, he only said that the Jiao family had something to do and would leave for a week.

"That's right." Xiong Xiong was not satisfied with Yi Xin's explanation, but he finally came again, and his mother didn't allow him to eat too cold recently, if he went out like this, he would definitely be criticized again, and it would be good to leave after eating the popsicle.

After thinking about it, Xiong Xiong asked Yi Xin: "You are from the Academy of Biological Sciences, right?" I have a question. ”

Yi Xin sat upright, "Please speak." ”

"I've heard that if you don't eat breakfast, you will eat, is it true?"

Zheng sighed, who was lying on the sofa with his eyes closed and pretending to sleep, but listened with his ears pricked up: "......"

Su An and Lan Tianzhu also looked at Yi Xin curiously, waiting for an answer.

The smile on Yi Xin's face collapsed a little, but he still made this question academic, thought about it for a while, and said, "Strictly speaking, it's not correct. After the food enters the small intestine, the nutrients are digested and absorbed, and the remaining residues enter the large intestine, and then they are excreted in the form of urine and urine. However, the large intestine is not like the small intestine, it has no absorption function, and can only absorb a small amount of water and inorganic salts. So even if you don't eat breakfast, those 'residues' in the large intestine won't be absorbed by you, so this proves that what you said is not true. ”

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

"You can argue with your mother." Lan Tianzhu spoke.

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

"What's the kneeling washboard, I also knelt on the keyboard two days ago, and I'm not allowed to get up if I don't kneel down that 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."

Zheng Si, Yi Xin: "......" this loser child!

"My dad didn't allow me to enter his lab anymore, and my mom withheld my pocket money for a month." Su An snorted.

"Actually......" Lan Tianzhu wiped his mouth, "It's illegal to physically punish children, right?" You can call 110. ”

"It's useless, I've beaten it." Xiong Xiong said indignantly, "After the fight, my mother changed to a bigger washboard and came over for me to kneel." ”

Zheng Si, Yi Xin: "......"

"His grandmother's, children have no human rights!" Xiong Xiong sighed.

Lan Tianzhu glanced at it: "Pay attention to quality." ”

"His grandmother's, children have no human rights!" Xiong Xiong said again.

Zheng Si, Yi Xin: "......"

As he spoke, Xiong Xiong picked up his trouser leg and asked a few people to see the red marks on his legs.

Zheng Si, Yi Xin: "!! ”

"You're so ruthless!" Lan Tianzhu and Su An swallowed their saliva.

"No," Xiong Xiong looked proud, "I pinched myself to cry a little more!" My mom relented and changed the original hour to 15 minutes of kneeling. ~”

Zheng Si, Yi Xin: "......" is a proud fart! What to be proud of!

Listening to the conversation between the three broken children, Zheng Si felt that he was really naïve back then.

And Yi Xin was also roaring in his heart at the moment: What the hell are the children now?

After the three little children finished nibbling on the popsicle, they reluctantly pulled up their schoolbags and left, and before leaving, they also reminded Yi Xin and Zheng Si, "There have been thieves in the compound recently, pay attention, several households have been stolen, don't lend out the access card, and don't let strangers enter the building." ”

After the three children left, Zheng Si and Yi Xin felt that the world had finally quieted down.

Boil water for cats, blow their hair, apply medicine, and entertain children...... At the end of the day, I was exhausted. Yi Xin decided to wait for Boss Jiao to come back, and he must apply for a salary increase! Definitely!

Zheng Si didn't care what Yi Xin was thinking, he was also tired now, these two days were enough to toss, thinking of Wei Ling's words, Zheng Si decided to go for a run tomorrow. It's rare that Zheng Si didn't go to bed at eight o'clock at night.

Yi Xin used Boss Jiao's computer to revise the paper, looked at the time, it was more than two o'clock in the morning, stretched out, turned off the computer and went to the living room to sleep on the sofa. When passing by Gu Youzi's room, Yi Xin looked inside, and through the light of the living room, he saw that on the children's bed in the room, a big Garfield doll was resting in the middle of the bed, and the black cat was lying on it, one leg curled up, and the other leg was pressed against Garfield's cheap big cake face, sleeping soundly.

Yi Xin pouted, no sleep!

In the dream, Zheng Si dreamed that his strength had grown and he had caught the thief.
