My abstract plant was exposed by my sister.

Lin Muyang took it; this time it was a gene sequence alignment diagram, with two curves drawn on it that almost completely overlapped.

"The gene segment mutated in the cactus has a similarity of 73 percent to the human DRD4 gene."

Xiao Kui stopped laughing: "How much?"

"Seventy-three percent. Humans and bananas share sixty percent of their genes, while humans and cats share ninety percent."

Seventy-three percent means that this gene in cacti has a very high degree of homology with that in humans.

Xiao Kui opened her mouth and turned to look at the middle finger guy. The middle finger guy immediately made a heart shape with his hands, although it was crooked, you could still make out the shape.

"It...is it related to us?" Xiao Kui asked incredulously.

"They're not related." Su Mingzhe said expressionlessly, "It's just a coincidence, but this coincidence is very interesting. It shows that some behavioral mechanisms of plants may share common evolutionary roots with animals."

The live chat was also bustling with activity:

Translation: Cacti and humans share a common ancestor.

"So, the cactus is my distant cousin?"

"I suggest registering a household for the cactus."

"It should have the surname Lin."

Xiao Kui took a deep breath, walked to the windowsill, squatted down, and looked directly at the man with the middle finger:

"Little brother, can you understand what I'm saying?" she asked earnestly.

The guy with the middle finger was silent for a second, then all his fingers turned towards her and he raised his middle finger.

Xiao Kui: "..."

"It understood."

It means you're the younger brother.

"Hahahahaha"

Su Mingzhe tidied up the documents and stood up: "The report is yours. If further functional verification is needed, we can do transcriptome sequencing again."

"The fee application has been submitted to Teacher Fang." He paused, glancing at the middle finger guy on the windowsill:

"You'll have to collect the sample yourself next time."

After saying that, he left without looking back.

Xiao Kui chased after him to the door and called out, "Senior Brother Su! Aren't you going to say a few words on camera?"

Su Mingzhe paused for a moment, then quickened his pace and disappeared at the end of the corridor.

When Xiao Kui returned to the lab, she found Lin Muyang squatting in front of the cactus, looking at it with an unprecedented gaze.

"Brother, what are you doing?"

Lin Muyang said thoughtfully, "I'm wondering, if it's sick, shouldn't it be treated?"

The guy with the middle finger gave him the middle finger.

Xiao Kui immediately burst into laughter: "Middle Finger Bro doesn't seem to want treatment."

Lin Muyang sighed, stood up, and placed the stack of genetic reports on the top shelf of the bookshelf. He turned to look at the three giant green tomatoes in the corner; they had turned pale yellow, and the veins were getting deeper and deeper, like wrinkled old faces.

Xiao Kui turned off the live stream, leaned against the control panel, and let out a long breath. She turned to look at the middle finger guy, who was pointing his middle finger at the setting sun outside the window. The golden light shone on his finger, giving it a touch of solemnity.

"Brother, do you think it knows what it's doing?"

Lin Muyang thought for a moment and said, "I don't know, but it should be very happy."

Xiao Kui laughed: "How do you know it's happy?"

"Because it gives the middle finger every day," Lin Muyang said without hesitation. "If you could also give the middle finger to anyone you don't like every day, you'd be happy too."

Looking at the middle finger guy, Xiao Kui suddenly felt that he wasn't so annoying anymore.

The guy with the middle finger turned around and gave her the middle finger.

"You're still annoying." Xiao Kui said sullenly.

The cactus replaced its middle finger with a "V" sign.

Xiao Kui laughed. Middle Finger Bro just doesn't like anyone. What bad intentions could it possibly have?

Meanwhile, on the other side of the city, a mother named Li Meifen is experiencing the most bizarre night of her life.

Li Meifen's son, Dou Dou, is eight years old and has been diagnosed with ADHD three years ago. Her experience of tutoring him every night can be summed up in four words: a living hell.

When DouDou does her homework, the chair isn't for sitting, it's for spinning; the pencil isn't for writing, it's for chewing; the eraser isn't for erasing, it's for chopping into tiny pieces. She can spend from seven to nine o'clock on a single two-digit addition or subtraction problem, finally writing "35 + 28 = 53," but it's still wrong.

Li Meifen had yelled at and cursed, and even thought about putting her son back into her womb and giving birth again.

Although the medicine was effective, the side effects were quite severe. DouDou stopped eating properly after taking the medicine, became as thin as a monkey, and couldn't sleep at night, even dancing around on the bed at 2 AM.

After discussing it with her husband, Li Meifen stopped taking the medication, since health is the most important thing.

Sure enough, after stopping the medication, DouDou turned back into a perpetual motion machine.

Until last week, a friend she had met when she took DouDou to see a doctor recommended something to her.

"Try this," a friend sent a link, explaining:

"I unintentionally put a potted plant on my son's desk, and he became much quieter when doing his homework, and his concentration was better than ever before."

Li Meifen clicked on the link, which led to a cactus with the title: "Middle Finger Cactus - A popular plant that makes the middle finger gesture, limited edition available."

Li Meifen was stunned: "You want me to treat my son's ADHD with cactus?"

"This isn't treatment, it's an adjunct. You'll see once you try it yourself."

Li Meifen hesitated for two or three days, but finally couldn't stand Dou Dou's stunt of cutting the rubber into snowflakes. She gritted her teeth and spent 1,200 yuan to buy a pot.

On the day the cactus arrived, Li Meifen opened the package and looked at the cactus that was giving her the middle finger, not knowing whether to laugh or cry.

Then he placed it in the upper right corner of DouDou's desk. DouDou glanced at the cactus, and the cactus immediately turned its head and gave him the middle finger.

"Mom, it's cursing at me."

"It's not insulting you, it's...encouraging you."

Is giving the middle finger an encouragement?

"Uh... that's its special way of expressing it. It's trying to say you're great."

DouDou opened her workbook with some skepticism. In the upper right corner, a cactus was pointing its middle finger, motionless.

That night, DouDou did her homework for forty minutes, only turning her chair once and chewing on her pencil once.

Li Meifen stood at the door, holding her breath, thinking she was seeing things.

On the second, third, and fourth days, DouDou's concentration time increased each day, and her accuracy in completing her homework also improved.

On the fifth day, he actually took out his homework and placed it in front of the cactus, saying, "Mom, I'll do math first today."

Li Meifen almost cried. The last time Dou Dou was this well-behaved was when she was just over two years old.

But she was a rational person, so she decided to conduct an experiment and secretly took the cactus away.

On the sixth night, while DouDou was taking a shower, she hid the cactus behind the flower rack on the balcony.

When DouDou came back from her bath and sat down at her desk, she suddenly noticed that the upper right corner was empty.

"Mom, where's the cactus?"

"It...it's sunbathing today."

DouDou didn't say anything, and lowered her head to start doing her homework.

But Li Meifen soon realized something was wrong. His legs started to tremble, his hands started touching the eraser, and his eyes started glancing out the window.

Twenty minutes later, he stood up, walked around the room, came back, wrote two words, and then stood up again.

Li Meifen quickly took the cactus back and put it back in the upper right corner.

DouDou sat down, glanced at the cactus, and the cactus immediately gave him the middle finger.

He smiled, lowered his head, and began to do his homework.

Li Meifen stood at the door, looking at the scene before her. Her son was quietly doing his homework, and the cactus was quietly giving her the middle finger. Suddenly, she felt that the scene was as absurd as a dream.

She realized that countless parents were unable to live normal lives because of their children with ADHD, so she immediately compiled her findings and posted them online.
