"Poof~"

The next second Dean Meng ran into the bathroom in a hurry, there were many farts inside, as impassioned as the March of the Volunteers, resounding in the sky.

Liu Lulu put down the book in surprise, looked at the direction of the bathroom, and said blankly, "Dean Meng, what's wrong with him?"

Xu Fan also put down his pen and said uncertainly: "It should be that you ate indiscriminately and ate your stomach, right?"

At this time, Xu Fan was not worried about Dean Meng's physical condition, he heard that as soon as Dean Meng entered the bathroom, there was a lot of fart noise, I don't know if he had time to take off his pants just now, but don't put a yellow and white thing in his pants when he arrives, it will really throw his face to his grandmother's house.

Xu Fan originally thought that Dean Meng would be able to stop in three or five minutes, but he didn't expect that when he entered the toilet, he would fart like a cannon without stopping for a moment, Xu Fan was really worried about whether his body could withstand this sin.

Xu Fan covered his nose and walked to the frosted glass door of the bathroom, through the wall, and said to Dean Meng inside: "Uncle Meng, are you okay?"

In the noisy fart sound, mixed with Dean Meng's weak voice: "You say I'm like this, why... How can it be okay..."

Xu Fan then asked, "Do you want me to go to the pharmacy and stop back?"

"Go... Hurry up, I'm afraid I'm about to pull out my anus!"

Xu Fan put on a coat and walked out of the house, bought a box at the pharmacy next to the community, and stopped home.

Xu Fan opened the door and went inside, and found that Liu Lulu, who was supposed to be next to the desk, was nowhere to be seen at the moment, but her bag was still lying quietly on the sofa, and it could be judged from here that Liu Lulu had not left.

She's not in the living room, so where would it be?

At this time, Xu Fan's eyes happened to catch the open door of his bedroom, and he clearly remembered that when he left the room in the morning, he had closed the door with his hand.

And at this moment, the door was opened, could it be that Liu Lulu entered his room?

Xu Fan said that he parked on the coffee table, walked towards his bedroom, glanced inside, and saw that the room was empty, and the door of the private bathroom in the bedroom that should have been open was covered.

"Liu Lulu, is that you?"

Xu Fan heard this, and Liu Lulu's weak voice came from the toilet: "Brother Fan, how long has your pure water not been changed, why did I start to have stomach trouble after drinking it for a long time." ”

Xu Fan frowned and thought about it, and said, "I changed it four or five days ago, the shelf life of pure water can't be so short, and I've been fine after drinking it for the past few days, you must have eaten it yourself." ”

"I eat breakfast at the same house every day, and I drank a glass of water from you today, so I will have a stomach upset, it must be that there is a problem with your water!"

Xu Fan swore so much when he heard what Liu Lulu said, he also doubted the problem of water sources, and decided to go out to find out.

Xu Fan walked out of the bedroom to the living room, and happened to bump into Dean Meng, who had just come out of the bathroom, holding a porcelain cup, taking half a bowl of hot water on the hot water outlet of the water dispenser, mixing it with the laxative stop agent and brewing it, drinking it with his head up, and then sitting on the sofa with his butt in his head, looking exhausted.

Xu Fan greeted Dean Meng twice, Dean Meng replied weakly, he saw Xu Fan staring at the bucket of clean water on the water dispenser, and couldn't help but ask softly: "Ah Fan, is this so?"

"Liu Lu... Teacher Liu said that there might be a problem with our water, so I came out to see if this was the case. ”

Xu Fan looked at the water quality inside with his eyes open and saw that the water was extremely clear and did not contain a trace of impurities.

Suspicious, he picked up the disposable plastic cup used to entertain guests, took half a bottle of water, put it to the tip of his nose and sniffed it, but he didn't smell any reason.

Just when Xu Fan was puzzled, he found that there were small floating objects on the surface of the water, Xu Fan put the cup at eye level, looked at it carefully, and saw that there were still a few wisps of white powder on the top that had not yet fused with the water.

Xu Fan's eyes looked back and forth between the pure water bucket and the cup, the water in the pure water bucket was clear, but the water in the cup was mixed with other substances, as expected, the problem should be on the water dispenser!

After some searching, when Xu Fan removed the pure water bucket on the water dispenser, he saw that on the water dispenser's water inlet, there was a solid mass similar to a white mothball, stuck on the water dispenser's filter.

Xu Fan stretched out two fingers and twisted the unknown thing, and Dean Meng saw it on the side and asked, "What is this?"

Xu Fan said uncertainly: "Laxatives?"

"Ah, no!" Dean Meng looked at the small half bowl of laxative stop medicine left in front of him with a stunned expression, and suddenly, he felt a wave of defecation in his abdomen, and then turned into a streamer and occupied the toilet again.

Xu Fan took a paper towel and put it on the table, crushed the white pill, and thought to himself when this thing was put in the water dispenser.

Suddenly, Xu Fan remembered that when he lived here with Aunt Yan, he had installed a monitoring probe in a hidden corner of the living room, in order to avoid Aunt Yan and sneak outside to do errands.

Since Aunt Yan left, she went out to be busy during that time, and she had forgotten about it to the clouds, and now this monitoring can just be used.

Because this monitoring is directly connected to the power supply, Xu Fan is not worried about it at all, he immediately ran back to the room, picked up a tablet that he had left in the cabinet for a long time, and operated flexibly on the screen with his fingers, and in the next second, he turned on a surveillance video.

The video, which began at twelve o'clock last night, showed that the hall was pitch black, and everything was quiet except for the sound of the clock on the wall.

Xu Fan clicked on fast forward, and the monitoring screen jumped rapidly, and when the time on the screen jumped to more than two o'clock in the morning, the time period when human beings slept the deepest, the door at the entrance of the living room was opened.

Xu Fan immediately came to his senses when he saw this, he resumed normal playing, and saw that after the door opened, a thin body entered the room.

The figure listened outside his bedroom for a while, and when he was sure that the occupants were asleep, he walked softly into the kitchen and tinkered with it for a long time.

When he came out, he walked to the water dispenser in the living room, carefully carried the pure water bucket, and then reached out and took out something and threw it into the water inlet, and placed the bucket properly, then patted his ass and turned away...

"This must have been instigated by Zhao Youxuan and her friend. ”

When Xu Fan thought of the pain experienced by Dean Meng in the toilet, he felt afraid, and his first reaction was to clean up all the hands and feet of the person who entered the house last night.

Therefore, Xu Fan first walked into the kitchen to look for a long time, and found that a lot of cooking seasonings had been added to it, and even in the tap water purifier that was vaguely placed under the sink, he also found something in the water dispenser that could cause diarrhea.

Regarding the oil, salt, sauce and vinegar in the kitchen, Xu Fan decided to throw them all away, but this matter is not the main thing, and now he is very angry, and he must find Gu Jin to talk about it.

With his memory, Xu Fan found Gu Jin's business card in the trash can, and dialed it according to the phone number above.

After the phone was connected, before Xu Fan could report to his home, Gu Jin on the other end said in a strategizing tone: "Mr. Xu, you call me, are you planning to sell the house?"
