Professor, your turtle!

The group tutoring for the biology competition was arranged during the lunch break, and Ji Fan packed his schoolbag and went to the office.

Because the team members were relatively small, Lao Xu only set up a small room next to the teacher's office as a classroom.

Xu Haifan originally said that he wanted to go to the class with him, but Ji Fan directly dismissed it—this guy usually gets sleepy when he listens to biology, and it’s okay to sleep in biology class. Kick out.

Therefore, he was the only one standing at the door of the small classroom now.

When Ji Fan opened the door and entered, the teacher hadn't come yet, and there was only a male student wearing glasses sitting inside, holding a large reference book.Hearing the voice, the man raised his head, his face was very strange, he was not a student of class S.

Ji Fan was stunned for a moment, then quickly exited to look at the house number.

That's right.He went back in embarrassment, only to see a suspicious look from behind the thick bottle bottom cap of the other party.The man's glasses were not very clean, he couldn't see his face clearly, his forehead was oily, and he looked like a schoolmaster who had stayed up too late.

Ji Fan gritted his teeth and said hello: "Hi, may I ask this place..."

"Biology competition group." The boy said, "Did you go wrong?"

Ji Fan quickly introduced himself, saying that he was a new auditor, but after the other party finished listening, he just nodded indifferently, did not report his family background, and continued to turn over the book and do the questions.

The room is very narrow, with four tables in the middle, like a conference room.Seeing that the other party didn't intend to continue talking to him, Ji Fan walked in and sat opposite the boy.

As he sat down, he glimpsed the title through his fingers—University Biology.This is a basic textbook for universities, and it is also a must-have advanced reading material for biology competitions. It can be seen that boys are indeed in the competition group.

It's just... Ji Fan was a little curious, this was the first time he saw students from other than Class S participating in the competition.

Students in ordinary classes seldom specialize in competitions. On the one hand, it is because of academic problems, and on the other hand, it has something to do with the curriculum arrangement.

When Class S arranges classes, most of them will take into account the students' competition courses, but ordinary classes will not.

For example, in lunch break or activity class, ordinary class teachers usually arrange quizzes and homework explanations. If students use this time to participate in competition tutoring, they will have to make up for leftover homework after class.

No wonder this little brother looks overworked.

"What are you looking at?" The man frowned and said in a bad tone, "Why did you come here?"

"Sorry, I..." Ji Fan was startled, and quickly lowered his gaze.

Scanning the papers on the table, he suddenly found that the other party seemed to have been stuck on a certain test question for a long time.

——I searched the information everywhere but couldn't find the answer, no wonder my face was full of irritability.

"You should choose B." Ji Fan saw the title clearly and subconsciously said, "Exocrine tissues are glandular hairs, drains and nectary glands, excluding milk ducts."

The boy finally raised his head, his eyes were slightly surprised, and he looked at Ji Fan squarely for the first time.

The line of sight shot from behind the "oil glasses" was very sharp. Ji Fan paused for a moment before mustering up his courage and said, "...The milk duct is an endocrine tissue, such as the duct that secretes rubber from the trunk of a rubber tree."

Seeing that the other party did not refute, Ji Fan swallowed, and said: "This is easy to memorize, just remember 'milk duct', and the names of the remaining three endocrine tissues contain the word 'secretion', and the names of exocrine tissues contain the word 'secretion'." No."

After listening quietly, the boy pushed his glasses and reached out to him: "Hello, my name is Chen Zhen."

Hearing this name, Ji Fan was stunned for a moment, the word "Chen Zhen" was very familiar to him - he seemed to be the only ordinary class student who entered the top 5 in the last monthly exam.

At that time, many people in the class privately compared Ji Fan with him, thinking that compared to Ji Fan, Chen Zhencai should be a member of the competition class.

Ji Fan shook hands with him, feeling unreal in his heart. Compared with the rumored arrogant persona of "high above", "looking at people with his nostrils", and "impolite", he himself seems to be much easier to get along with .

——At the beginning, it was just a few words.

"Thank you." Chen Zhen smiled.

Ji Fan blushed, and he unconsciously said the words "looks easy to get along with".

Chen Zhen took off his glasses, wiped them slowly with a lens cloth, and said lightly, "I think you're good, too, compared to the rumors." He deliberately emphasized the last four words, and glanced at them pointedly, "You can see what you see, you can see what you see." It is true, what you hear is false.”

Ji Fan: "..." He could probably guess what kind of trash the other party described him as in the rumors he heard.In a sense, they are really in the same boat.

After taking off the glasses, Ji Fan finally saw his face clearly.To be honest, Chen Zhen is not ugly, with slender eyebrows and eyes, which may be due to wearing glasses all the year round. The bridge of his nose is not so straight, but it fits his fox eyes just right.

In fact, Ji Fan has always been very curious. With Chen Zhen's grades, it is easy to enter Class S. Why was he not included in the class list at that time?

Just as he was thinking, Chen Zhen had put back his glasses and restored his "greasy" image of a schoolmaster.

The door opened, and a few students from Class S came in. They looked at Chen Zhen's oily hair with a bit of distaste, and then sat on Ji Fan's side.

Wang Gang was among them.For some reason, when he saw Ji Fan, he froze for a moment, then quickly turned his face away.

——Is this person still embarrassed about doing the duties that day?

Ji Fan glanced at him suspiciously, and saw that the other party's expression was stiff, and he buried his face even deeper, wishing he could shrink into the textbook.

"Ah, I'm sorry, it's a bit late." Old Xu strode in hurriedly, holding the lesson plan in his left hand, with a potted flower under his right arm, and could only hook the door with his feet.

He moved to the edge of the podium and put down the things in his hands: "Have you met everyone? This is the new classmate Ji Fan today." Having said that, he only looked at Chen Zhen, the only one who did not belong to Class S.

Seeing Chen Zhen nodding, he breathed a sigh of relief: "Here, this is the answer to yesterday's multiple-choice question. Chen Zhen, please read it. Everyone is right. I'll turn on the computer first..."

"Yeah." Chen Zhen stood up calmly, "ABCAB, DD..."

He reported it twice, and everyone buried their heads in correcting it.Ji Fan was relieved when he heard that the question he had answered earlier should have chosen B. It would be too embarrassing if he remembered it wrong.

Just as he was thinking, Ji Fan secretly glanced at Chen Zhen, only to see that the other party was also staring at his... paper thoughtfully.

This breakthrough volume on botany was completed by him last night.With the addition of the system, Ji Fan's memory has been greatly improved, and he is like a duck to water in the biology test paper. Right now, he only got one multiple choice question wrong in this paper.

Against the background of the crowds of students with red crosses and mourning, he is particularly eye-catching when he is close to being completely right.

Ji Fan subconsciously wanted to explain, but Chen Zhen didn't have a single extra word, so he casually turned his eyes away.

Old Xu finally got the ppt done, and straightened up: "When I graded the paper last night, I found that the plant tissue is very weak. Come on, let's focus on reviewing."

After explaining the basic knowledge, Lao Xu really brought up the question of "exocrine tissue": "Which of the following does not belong to 'exocrine tissue'. If you memorize this question, you will get points. How can you make so many mistakes?"

"Many people reported to me that 'glandular hairs' and 'secretory cavities' are not clear, because they are both on the surface of the plant..." Old Xu put the potted flower on the podium heavily, and took out another tangerine.

"Come on, touch it, and see where the difference is."

The flower is geranium, and there are typical "glandular hair" tissues on the surface of its leaves, while the uneven dots on the surface of citrus are "secretory cavities" containing aromatic oils.

Like a pickpocket, Lao Xu held up the orange peel in one hand and the leaf in the other, calling for the students to come up and "touch and see".

"Touch it yourself, is there a bump on one side, soft, wet, and a little hairy; while this side is smooth?" He said, "This is the difference between 'glandular hairs' and 'secretory cavity',' The glandular hairs protrude from the leaves, just like the hairs on your skin, don't make a mistake in the future!"

This pot of geraniums sprouted exceptionally high and looked healthy.

The students all stretched out their hands curiously, stroking the leaves, and even some naughty ones turned to tease its unopened flower cores, and picked the soft and tender buds, trembling non-stop, even wet. The juice was shaken off.

As soon as Ji Fan touched the leaves, his expression changed slightly.

-I'm sick.

He seemed to hear the sobbing voice of the plant: "Don't touch it, it's so annoying! They are sick and have to be picked up|guests."

It seems to be a clear and clear young male voice, if you listen carefully, it looks like a sister Yu who deliberately lowered her voice, with a bit of indistinguishable taste.

Ji Fan let go of his hand in fright, and the voice disappeared immediately, as if it was just a hallucination.

He tentatively touched the leaves again, but this time nothing happened.

Seeing the bush of flowers trembling under the claws of the mischievous male classmate, Ji Fan felt blocked for some reason, and blurted out: "Don't touch it."

"?" The boy who had the most fun turned his head and said dissatisfiedly, "What's wrong? A potted flower, just touch it, but it won't break it."

Ji Fan frowned: "He's sick."

"Just kidding," the boy sneered, and poked the geranium's sprouts. "Look at how straight it is, how could it be sick?"

No, that's not the case, Ji Fan looked down at the potted flower, the leaves were yellowish and the number of buds decreased.Something must be wrong.

Hearing the dispute between the two, Lao Xu came over: "What's wrong?"

"Ji Fan said that this flower is sick." The boy said quickly, "Don't talk nonsense, it looks very good."

Old Xu froze for a moment, then turned to Ji Fan: "What did you see?"

Hearing this, everyone around stopped making trouble and looked at the two of them together.

——Could it be that there is something wrong with this flower?

Ji Fan paused for a moment, then asked in deliberation: "Is this pot of geraniums...have fewer flowers this year?"

Old Xu's eyes widened: "That's right, that's right." He gently squeezed the lovely round leaves, and said, "This was originally raised by my father, but this year, for some reason, only this pot has not bloomed. At first I thought it was because the old man was too cold on the balcony, and planned to let me stay here for a few days, but I couldn’t find the fault, so I thought it was because of the breed.”

After finishing speaking, he turned to Ji Fan: "I have fertilized several times, and the light and temperature are all in accordance with the regulations. What do you think is the problem?"

Everyone was looking at him, even Chen Zhen, who had always been a loner, stood far away at the edge of the crowd, and his eyes were firmly locked on him under the glasses.

Ji Fan swallowed his saliva, and said slowly: "Now should not be the season for sprouting, but he is desperately growing taller, which can be seen as 'plant growth'."

"Look here again, the edges of the leaves are turning yellow." Ji Fan paused, and then expressed his guess, "Geraniums like to dry, and if this happens, the environment may be too humid."

"Impossible," Old Xu shook his head violently, "All the pots of flowers are watered in the same way, and the other pots of geraniums are normal."

Ji Fan frowned and said nothing: Judging from the current situation, it is indeed because of too much water, but why...

The boy who was completely stunned was relieved when he saw this, and said, "What, I thought you suddenly became an expert, but after talking for a long time, it was just a wild guess."

At this moment, Chen Zhen pushed everyone away without saying a word.

Old Xu was full of doubts: "Chen Zhen?"

His movements were simple and rough, and he lifted the pot of flowers above his head without hesitation.

"Hey wait, what are you doing?" Old Xu was sweating profusely, "Don't be impulsive, this is my dad's most precious pot of flowers!"

"Here." He took a few glances, raised his chin expressionlessly, and motioned for everyone to look.

I saw that only one of the small holes at the bottom that was originally used for water penetration left wet traces, and the rest were very dry.

"Could it be blocked?" Old Xu was suddenly taken aback, reached in and hooked it, and even touched a thin layer of plastic film.

His face immediately darkened: "No wonder!"

——Five water holes, four of which are blocked by this plastic film, so the water can't seep out, isn't it damp?

For geraniums that like to dry, if they stay in such a flower pot all day long, they will be ghosts if they don't get sick!

For a moment, Old Xu's eyes changed when he saw Ji Fan, and he patted him on the back: "My God, how did you guess that? Did you grow flowers at home?"

The boy who choked on Ji Fan earlier turned red, and retreated, embarrassed to speak.

Ji Fan shook his head and remained silent.

"You are just modest. My dad also planted a lot of flowers, and there are always minor problems. If you are free on weekends, come and help me..."

Ji Fan was embarrassed by the praise.To be honest, he had never touched geraniums, or even grown flowers.Just because I don't have experience, I don't know the effect of the structure of the bottom of the pot on the soil condition.

However, as soon as I saw the pot of geraniums just now, I instinctively began to analyze various causes of the disease.

Coupled with that weird voice that suddenly appeared in my head earlier...

Ji Fan's gaze fell back to the pot of trembling geraniums.

What exactly is going on?
