Shaking off the water on his body, he picked up a stone and drove the noisy parrot away. Zheng Tan put the things back on his neck on the tree where the keys and access cards were hidden, slid down the tree, and headed towards Jiao's house.

Lou trotted over.

I jumped up, swiped the access card, and ran all the way to the fifth floor.

Because it is an old building, many residents keep grille security doors. The same is true for the Jiao family. However, the door lock of the metal grille security door of the Jiao family is broken. The security of the family building is relatively high, and it is a five-story building.

Usually no one comes up to the building, so it has not been repaired. A wooden door is enough.

The grille security door is wide open against the wall so as not to block people's entry and exit, because the door body is very rusty over the years.

Zheng Tan jumped on the metal grille door, hooked the upper grille near the door lock, clung to it, then raised his legs and pushed hard against the wall. The grille door led Zheng Tan toward the door, rusty

The door shaft made a sharp creaking sound.

As Zheng Tan approached the door lock and was about to insert the key, the door opened from the inside.

Yi Xin borrowed Associate Professor Jiao's computer to write his thesis last night and fell asleep on the sofa until almost dawn. He woke up from urinating and went to the toilet. As soon as he lay down on the sofa in a daze, he heard the sound at the door.

There was a loud noise, and I ran to the door to open the door without even putting on my shoes. Boss Jiao had 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 sound of the grille door, but when he opened the door, he knew it and was stunned. In front of him, a black cat twitched its legs and

The furry paw hooked on the metal bar on the grille, holding a key in his mouth, and with the creaking sound of the grille door shaft, he approached the door lock.

Zheng Tan obviously didn't expect that there would be anyone at home, and he looked a little familiar.

Zheng Tan was thinking about who the person in front of him was, while Yi Xin was in a daze. For a moment, one person and one cat stared at each other.

In the end, Zheng Tan was the first to remember the identity of the person in front of him. When Zheng Tan was secretly taken by Jiao Yuan and the others to Jiao's dad's office, Jiao's dad had told him about Yi Xin. At that time, Yi Xin was leading undergraduate students to do experiments.

, and several other graduate students walked towards the public laboratory carrying samples, Jiao's father stood at the window and pointed at what he told Zheng Tan.

Now that the identity of the person in front of him was confirmed, Zheng Tan didn't care anymore. Being able to come in must have been approved by Father Jiao, and anyone who could get Father Jiao's approval must be trustworthy.

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

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

Zheng Tan looked at the snacks that had moved out of place, counted them, and found that there were no less, and he felt a little satisfied.

Yi Xin was still standing there in a daze. Although he had recovered from the scene at the door, he was shocked by the scene on the other side of the chair. When he called Boss Jiao yesterday, Boss Jiao also told him not to eat on the sofa.

If you want to eat the snacks on the table, eat the ones stored in the second compartment of the refrigerator, but don't eat any of the ones originally placed on the sofa.

Yi Xin didn't understand when he was on the phone, but now he understands that the cat just stared at the snacks on the chair and nodded his chin. Was he actually counting them?!

Zheng Tan ignored Yi Xin who was in a daze. He was very hungry now. He bit open the plastic packaging on the pudding and started eating.

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

Zheng Tan listened to the phone calls in the bedroom.

Yi Xin took the phone and said "Oh, oh" twice, then turned on the speakerphone. Dad Jiao's voice came from the phone: "Heitan, answer the call."

Zheng Tan raised his head: "Wow——"

Yi Xin: "..." The cry is a little bit special.

"Sounds like he's in good spirits," Dad Jiao said, and then asked Yi Xin to turn off the speakerphone, and he also had some words to say to Yi Xin.

Yi Xin held the phone and answered respectfully, but the expression on his face was helpless. After finishing the call, he went to the kitchen to boil water, pulled out a white plastic basin on the basin rack, and washed it.

Yi Xin once heard someone say before going to graduate school that it is best to choose a tutor whose children are old enough and do not have pets at home, so as not to have to help take care of the children and take care of the pets. At that time, Yi Xin thought that everyone was just talking about it for fun.

, I didn’t expect that now it was my turn. I didn’t need to take the child with me, but this pet...

While adjusting the water temperature, Yi Xin thought, he won't be sent to take care of pets often in the future, right? He must apply for a salary increase when Boss Jiao comes back!

When Zheng Tan walked into the bathroom, he looked at the water in the basin and raised his palm to touch the outside of the plastic basin to test the temperature. It was neither hot nor cold. As expected of a researcher, Zheng Tan knew the temperature accurately.

Then he looked at the special shower gel next to the plastic basin, the towels stacked on the low stool, and the hair dryer placed there. He jumped into the plastic basin with satisfaction, used a squeegee to pull the hair on his head, and then rested his chin on it.

On the edge of the basin, he squinted his eyes and began to take a bath.

Yi Xin, who was standing at the door, had already thought of thousands of alpacas racing a hundred times. He had seen relatives who raised cats before and their hands were bloody when they were being scratched while bathing the cats. This was the first time he saw this.

A cat enjoying a bath with squinted eyes.

As expected of... Boss Jiao’s cat.

When Zheng Tan felt that the water was a little cold, he was about to get up and wipe his hair. When he turned around, he found a bug the size of a sesame seed floating on the water with its legs still moving.

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

Yi Xin at the door was counting the time. He could estimate the temperature of the water in the basin without a thermometer. He was also wondering why the cat inside hadn't come out yet. He took a look and saw the black cat staring at him like a king.

Wearing a plastic bathtub.

What's going on? Yi Xin thought about what Boss Jiao said and felt that there was nothing missing, but he still felt uneasy and cautiously moved over. Soon, Yi Xin's eyes fell on the bug on the water as a bacterial picker.

Yi Xin is an expert at picking colonies, so naturally a small insect cannot escape his eyes.

Damn it, flea!

What to do if there are fleas?

Get killed!

Then what?

have no idea.

Yi Xin couldn't decide, so he ran to the bedroom and called Boss Jiao. Five minutes later, Yi Xin came to a cabinet and opened the door. There were some household chemicals inside, including two bottles of insecticide and one bottle of insecticide.

The other bottle of the more famous pyrethroid pesticide has no name. The one Yi Xin is looking for is the one with no name. This is probably one of the results of a pesticide project jointly conducted by Biotech and the Institute of Chemical Engineering some time ago.

, currently only some insiders have access rights.

Yi Xin followed Boss Jiao's instructions and sprayed some in several places in the house. As for Zheng Tan's side, he changed the water and soaked it again.

The most annoying thing is fleas. There are also fleas in the grass around the family area. However, Zheng Tan often played there during this period and never got into trouble with them. Unexpectedly, he really got them all over this trip. It must be in the suburbs.

In the thick grass over there.

Every time Zheng Tan found a flea in the water, he would kill it with his claws. Even those that were suspected of being drowned, Zheng Tan would not let go. In this way, Zheng Tan repeatedly soaked for two hours before coming out and rolling on the towel.

Yi Xin took a hair dryer to help blow the hair, "Black Charcoal, Teacher Jiao said that the insecticide is almost gone, so you... go find someone to get it yourself, and get some medicine to apply on it."

Yi Xin didn't know why Boss Jiao said that, he just asked him to follow the cat when the time comes.

Yi Xin cried a lot of tears in his heart. Taking care of his pets was more troublesome than writing a thesis.

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

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

Zheng Tan led the way, and Yi Xin followed.

Yi Xin's heart was full of doubts, but when it came to a cat, it was obviously useless to ask, and it was equally uncomfortable to hold it in his heart.

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

"Here? Let me ask..."

Before Yi Xin finished his mental preparation, Zheng Tan jumped up and hit the grille security door of this house with a volleyball smash.

"Boom!"

Yi Xin's hair almost stood on end. Although he didn't know who lived here, he also knew that most of the people living in the Dongjia District were seniors. He couldn't afford to offend him. A list appeared in Yi Xin's mind.

Now Yi Xin just hopes that the people here will not be any of these people!

Zheng Tan didn't care what Yi Xin was thinking anxiously now. He patted it twice in succession, each time louder than the last.

After the third filming, someone inside finally responded.

"Come on, come on! If you knock three times, do you think I'm deaf?"

The voice sounded like that of an old man. It seemed that the voice was familiar. Yi Xin was nervous.

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

Seeing this man, Yi Xin felt a chill in his heart.

"Lan...Professor Lan Lanlan!"

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

It's a pity that Zheng Tan ignored Yi Xin at all and walked in. He was not afraid of this old man. This old man owed him a favor.

The interior of the house was very plain, and there were water stains on the floor.

Although Zheng Tan had just taken a shower and blow-dried, the hair on his feet was not completely dry. There was some dust on his feet when he went downstairs, and now he left muddy footprints on the floor.

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

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

Professor Lan stared at the figure who walked in struttingly, then looked at the cat's footprints on the floor, turned to Yi Xin and said, "You will wipe the floor later!"

Yi Xin: "..."

Paralyzed people hate having pets, especially cats!
