Shaking the water on his body, scooping up a pebble to drive the noisy parrot away, Zheng Si put the thing back on his neck on the tree where the key and access card were hidden, slid down the tree, and trotted towards the Jiao family's building.

Jumped up and swiped the access card and ran all the way to the fifth floor.

Because it is an old building, many residents keep the grille security door, and the Jiao family is also like this, but the metal grille security door lock of the Jiao family is broken, and the security of the family building is relatively high.

The grille security door is wide open against the wall, so as not to block people from entering and exiting, because there are many rusts on the door body for some years.

Zheng Si jumped on the metal grille door, hooked the grille above it near the door lock, squeezed on it, and then raised his leg to force against the wall. The grille door leaned towards the door with Zheng Si, and the rusty door shaft made a creaking and sharp grinding sound.

When he was about to get close to the door lock, Zheng Si was about to insert the key, but the door opened from the inside.

Yi Xin borrowed Associate Professor Jiao's computer to write his thesis last night and wrote it until almost dawn before he fell asleep on the sofa, until he was woken up by urine, got up and went to the toilet, and just lay down on the sofa in a daze, when he heard the movement at the door, he bounced up, and his shoes didn't have time to put on and run to the door to open the door. Boss Jiao said that the grille door would ring when his cat came back.

Yi Xin never understood the connection between the return of Boss Jiao's cat and the ringing of the grille door, but when he opened the door, he knew it and was stunned. In front of him, a black cat hooked a metal strip on the grille with its legs and hairy paws, and a key in its mouth, and approached the lock with the creak of the lattice shaft.

Zheng Si obviously didn't expect that there would be someone at home, and it looked a little familiar.

Zheng Si was thinking about who this person was in front of him, while Yi Xin was in a state of stunnedness, and for a while, a person and a cat stared at each other.

In the end, it was Zheng Si who remembered the identity of the person in front of him first, when Zheng Si was secretly taken to Jiao Yuan's office by Jiao Yuan and them, Jiao's father had told him about Yi Xin, Yi Xin was taking undergraduates to do experiments at that time, and several other graduate students were walking to the public laboratory with samples, and Jiao's father stood at the window and pointed to tell Zheng Si.

Now that the identity of the person in front of him has been confirmed, Zheng Si didn't care about it anymore. Being able to come in must have been approved by Jiao's father, and those who can get Jiao's father's approval must be trustworthy.

Zheng Si jumped down from the grille door and went straight to the sofa.

In order to make it easier to sleep, all the snacks piled up on the sofa were put on the chair next to Yi Xin.

Zheng Si looked at the snacks that had been moved, counted them, and suddenly felt a little satisfied.

Yi Xin was still standing in place, stunned, although he had recovered from the scene at the door, he was shocked by the situation on the other side of the chair. When I called Boss Jiao yesterday, Boss Jiao also told him not to eat snacks on the sofa, and if he wanted to eat them, he would eat those stored in the second compartment of the refrigerator, but don't eat any of the ones that were originally placed on the sofa.

Yi Xin didn't understand when he called, but now, he understood, the cat just now stared at the snacks on the chair and nodded, that was actually counting, right?!

Zheng Si ignored Yi Xin, who was stunned, he was very hungry now, bit open the plastic packaging on the pudding, and ate it.

Yi Xin looked at the black cat eating the pudding on the sofa, twitched his face, and then moved his feet to the bedroom and called Boss Jiao.

Zheng Si supported his ears to listen to the movement of the phone call in the bedroom.

Yi Xin took the phone and said "oh, oh" twice, then turned on the speakerphone, and Jiao's father's voice came from the phone: "Black charcoal, answer." ”

Zheng sighed and raised his head: "Wow-"

Yi Xin: "......" is a little special.

"Sounds pretty good," Jiao's father said, and then asked Yi Xin to turn off the hands-free, and there were still some things to tell Yi Xin.

Yi Xin held the phone and responded respectfully, but the expression on his face was very helpless, and after he was done, he hung up the phone, came to the kitchen to boil water, dragged out a white plastic basin on the basin rack, and washed it.

In the past, Yi Xin heard people say before he was in graduate school that it was best to choose the kind of child who had enough children to have no pets, and he had to help take care of the pets when he could save the time. You don't need to bring a child, but this pet ......

While adjusting the temperature of the water, Yi Xin thought that he wouldn't be sent over often to take care of his pets in the future, right? When Boss Jiao comes back, you must apply for a salary increase!

When Zheng Si walked into the bathroom, he looked at the water in the basin, raised his palm and touched the plastic basin to test the temperature. Zheng Si looked at the special shower gel next to the plastic basin, the towels stacked on the low stool and the hair dryer resting there, jumped into the plastic basin with satisfaction, pulled the hair on his head with the water, and then rested his chin on the edge of the basin, squinted his eyes and began to take a bath.

Standing at the door, Yi Xin's heart of the 10,000 alpacas has galloped a hundred times, a hundred times, he has seen a relative who has a cat before when he bathes the cat and his hands are bloody, this is the first time he has seen this kind of cat squinting and enjoying the bath.

Worthy of ...... Boss Jiao's cat.

When Zheng Si felt that the water temperature was a little cold, he was about to get up to wipe his hair, but when he turned his head, he found that a sesame seed-sized insect was floating on the water, and his legs were still moving.

Against the backdrop of the white plastic basin, this little bug is quite eye-catching.

Yi Xin at the door calculated the time, he could estimate the temperature of the water that appeared in the basin without a thermometer, and wondered why the cat inside hadn't come out yet, and when he looked at it, he saw the black cat staring at the plastic bathtub with angry eyes.

What's going on here? Yi Xin thought back to Boss Jiao's words and felt that there was nothing missing, but he was still not at ease, and carefully moved his steps over. Soon, Yi Xin's eyes fell on the insect on the water surface, as Yi Xin, who was a good pick at bacterial colonies, a small insect naturally couldn't escape his eyes.

Nima, fleas!

What to do if you have fleas?

Kill!

And then what?

I don't know.

Yi Xin pondered, ran to the bedroom and called Boss Jiao, five minutes later, Yi Xin came to a cabinet, opened the cabinet door, there were some household chemicals in it, there were two bottles of insecticides, one bottle of the more famous pyrethroid insecticide, and the other bottle had no name. Yi Xin is looking for this nameless, which is probably one of the results of a pesticide project research cooperated by the Institute of Biology and the Institute of Chemical Industry some time ago, and only some insiders have the right to use it at this stage.

Yi Xin sprayed some in several places in the house according to Boss Jiao. As for Zheng Si's side, the water was changed and soaked again.

The most annoying thing is the long fleas, and there will also be fleas in the grass around the family area, but during this time, Zheng Si often played there and never got into trouble, but he didn't expect to really get into trouble when he went out this time, it must be in the thick grass in the suburbs.

Every time Zheng Si found a flea in the water, he directly wiped it with his claws, even if those who were suspected of having drowned, Zheng Si did not let go, so Zheng Si repeatedly soaked for two hours before coming out and rolling on the towel.

Yi Xin took a hair dryer to help blow his hair, "Black charcoal, Teacher Jiao said, that insecticide is almost gone, let you ...... I went to find someone to ask for it, and by the way, I went to get some medicine to apply. ”

Yi Xin didn't know why Boss Jiao would say that, just let him follow the cat when the time came.

Yi Xin bowed to himself with tears in his heart, serving his pet was more laborious than writing a paper.

After the hair on his body was basically dried, Zheng sighed and shook his hair, walked to the door, and looked back at Yi Xin.

Yi Xin remembered Boss Jiao's words, hurriedly put down the hair dryer in his hand and followed, took the key, and opened the door.

Zheng Si led the way in front, and Yi Xin followed behind.

Yi Xin's heart was full of suspicion, but in front of a cat, it was obvious that it was a vain question to ask, and it was equally uncomfortable to hold it in his heart.

Zheng sighed down two floors and stopped in front of a house on the third floor.

"Is it here? I ask ......"

Before Yi Xin, who had finished his psychological construction, jumped up and slapped a volleyball smash on the grille security door of this house.

"Boom!"

Yi Xin's hair almost stood on end, although he didn't know who lived here, but he also knew that most of the people living in the East Family District were old seniority, he couldn't afford to offend, Yi Xin had a ranking list in his mind, and now Yi Xin only hoped that the people in this area would not be any of these people!

Zheng Si didn't care what Yi Xin was thinking about now, he slapped it twice in succession, each time louder than the other.

After filming for the third time, someone in it finally responded.

"It's coming, it's coming! Also knock three times, when I'm deaf? ”

Listening to the voice is an old man, it seems, this voice is still a little familiar? Yi Xin was nervous.

The door inside opened, and the lock of the grille door was pushed open, revealing a taut old face.

Seeing this person, Yi Xin felt cold in his heart.

"Lan ...... Professor Lan Lanlan! ”

Looking at the old man with a serious face in front of him, Yi Xin had the urge to turn around and run.

It's a pity that Zheng Si didn't pay attention to Yi Xin at all, and walked in with his feet, he was not afraid of this old man, this old man owed him favors.

The interior of the house is very plainly furnished, and there are water stains on the floor.

Although Zheng Si had just taken a bath and blown his hair, the hair on his feet was not completely dry, and he went downstairs and was stained with some dust, and at this moment he stepped on the floor with mud on the paw prints.

"Little bastard! I just mopped the floor! Professor Lan scolded.

Zheng Si tugged at his ears, ignored it, and walked straight in.

Professor Lan stared at the back of the swaggering walking in, looked at the cat's footprints on the floor, turned to Yi Xin and said, "You will wipe the bottom plate later!" ”

Yi Xin: "......"

Paralysis hates pets the most, especially cats!
