saturation concentration

The expression on Sui Cannong's face was very complicated. He seemed very anxious, but he seemed hesitant to speak, which made Ji Ling startled.

"Ji Ling," then he heard Sui Cannong say, "I can't take it."

This is the first time Ji Ling heard that Sui Cannong did not call herself "Teacher Ji" at school, but called her full name seriously and formally.

Ji Ling's heart sank suddenly, and he felt a little lost.

But he knew that since he had the right to send flowers, Sui Cannong naturally had the right to refuse.

Sui Cannong already has a lot of flowers and plants in his classroom, maybe he doesn't want to add more burdens to himself.Although he didn't understand, Ji Ling still didn't want to embarrass Sui Cannong.

Ji Ling blinked slightly, trying to make her expression look calm.

He raised his face and nodded nonchalantly: "It's okay, I know there are already a lot of flowers in your classroom."

Sui Cannong opened his mouth slightly, but couldn't speak.

The behavior and words and deeds of Ji Ling sending flowers, as if for some special reason, she was eager to entrust this potted flower to herself.

If Sui Cannong wanted to raise this flower, he would definitely be able to raise it well.

The problem Sui Cannong doesn't know now is whether Ji Ling is really tired of raising Ji Ling and doesn't want to raise it anymore, or for some other reason, he has no way to raise it anymore.

"I can't take it..." Sui Cannong paused, and opened his mouth with difficulty, "It's because you have been raising this flower for too long and with such care. There are already a lot of flowers and plants in my classroom. Give it enough care."

Ji Ling looked at Sui Cannong, but didn't speak.

"Flowers and plants also have life. I think you are reluctant to raise them for so long." Sui Cannong said a lot in one breath, "If this is the case, then don't give it to others, and continue to keep it well It grows until next spring."

Sui Cannong's words here are very meaningful. Growing flowers is one thing. At the same time, he is also implying that Ji Ling himself should live a good life, but Sui Cannong doesn't know if Ji Ling can understand.

Ji Ling looked a little confused.

But he didn't say anything more, he just hummed lightly at last, and said to Sui Cannong: "I understand."

However, Sui Cannong felt that Ji Ling didn't understand at all.

Although he persuaded Ji Ling to take the flowers back for the time being, Sui Cannong didn't feel much relieved on the way back to his classroom.

One is because Sui Cannong found that when he left just now, the expression on Ji Ling's face was somewhat disappointed.

Sui Cannong couldn't describe Ji Ling's expression at that time, he just stood quietly beside the pot of rose flowers, eyes lowered, the expression on his face seemed a little dazed and a little sad.

Sui Cannong's chest felt a little tight, he only knew that if he looked at Ji Ling's face for a while longer, he might really have the urge to put away the pot of rose flowers.

The second is because he realized that Ji Ling was already planning something now, and he began to entrust some important and hard-to-break things around him to others.

This gave Sui Cannong a very bad feeling, because he knew very well what Ji Ling's plan was.

Therefore, Ji Ling's feeling to Sui Cannong is no different from explaining the funeral. Sui Cannong only knows that he can't accept the potted flower now, and he dare not accept it. He is terrified.

But what's the use of this? After he refused, Ji Ling could entrust the pot of flowers to other people, and his thoughts would not change a bit.

Sui Cannong really had a splitting headache.

He took a deep breath, stood up, and decided to let his mind go for a while and water the flowers in the classroom.

The pot of small tomatoes planted by Cindy and Shirley is growing very well. They just used chopsticks to make pillars a few days ago, and it is estimated that in half a month, they will be able to produce flower buds and produce some small fruits.

The two sisters would draw and draw on the little tomato for a long time after school every day. Cindy and Sui Cannong said that during the exam week, it was this pot of tomato that supported them to go to school, and it was their only sustenance at that time. .

support... sustenance...

Sui Cannong stared at the tiny fluff on the stem of the tomato for a while.

He suddenly had an idea.

"You can introduce the classification of damping here, and add some explanations for the natural frequency at the end," Ji Ling said, "it will make the reading more fluent."

Cindy stared at the computer for a while, pointed to the screen and said, "But there is still a lot of space here, can I increase the font size..."

Shirley said: "If you make it bigger, the final printed characters will be bigger than your head!"

Cindy was sullen and speechless.

"Add the two points I just said first, maybe the empty space has been almost filled, and finally you can add some pictures." Ji Ling said, "You have done a good job, don't worry, Let's go home first."

The science fair topic that Shirley and Cindy chose was "Resonance of Bridges", but the relevant content in the textbook was relatively small, and their progress was not fast at the beginning.

But the attitude of the two girls is very serious, so Ji Ling is willing to tell them more.

Either during the lunch break at noon or after school, Ji Ling would give them some extra tutoring to help them improve their progress.

The two little girls stood at the door with their schoolbags on their backs, said goodbye to Ji Ling crisply, and Ji Ling waved to them.

After a busy afternoon, Ji Ling felt a little tired, and after suddenly being free, he didn't know what to do.

Ji Ling's gaze first fell on the pot of roses on the window sill, and after a while he looked away, stood up, and began to wipe the whiteboard behind him.

Ji Ling had just packed her things, and when she walked to the door of the classroom and was about to turn off the lights, there was some movement from the other end of the corridor.

Ji Ling turned her head and found that it was Shirley and Cindy who were running towards Ji Ling panting with their schoolbags on their backs.

"What's wrong?" Ji Ling was stunned for a moment, "Did you forget something?"

Shirley shook her head and said, "Mr. Ji, Mr. Sui told us to tell you that he wants you to go to his classroom."

"And he asked the two of us to help you." Cindy added, "He said he wanted us to move the rose flowers from your classroom to his classroom."

When Ji Ling came to the door of the biology classroom, he saw Sui Cannong with his back turned to him, tinkering with something in the classroom.

The two little girls put rose flowers on a desk, and Cindy pointed out a small green plant to Ji Ling, and said, "Teacher Ji, look, this is the little tomato we raised."

Ji Ling said: "It looks good."

At the same time, Ji Ling also noticed that there are indeed a lot of flowers and plants in Sui Cannong's classroom, and most of the pots have a student's name on them.

For example, on the basin of Shirley and Cindy, there is a sticky note with "Sherry&Cindy" written on it.

Shirley and Cindy said goodbye to Ji Ling again, and when Ji Ling turned her head, she found that Sui Cannong had turned around and was looking at herself with a smile.

Ji Ling looked at Sui Cannong, he felt his face was a little stiff, and he didn't know what to say for a moment.

Sui Cannong said directly: "Mr. Ji, I thought about it again. I really get tired of looking at a pot of flowers, so I can actually help you raise your pot of roses."

"But in exchange, can you also do me a favor?" Sui Cannong said.

The sudden change in Sui Cannong's attitude made Ji Ling startled for a moment, and after a while he said, "It's ok."

Sui Cannong hummed first, then Ji Ling saw him turn around, and brought out a large plastic basin from behind.

What's in the basin... Ji Ling can't describe its texture, it looks like a white cylindrical plaster body, but the surface is rougher, and it's wrapped in a transparent membrane cloth.

"This is a potted mushroom." Sui Cannong said, "It's actually a fungus bag. Although it looks like a solidified mud lump now, tear off the membrane and spray water regularly, and it will start to grow."

"Mushrooms can grow many times." Sui Cannong looked at Ji Ling, "And the mushrooms that grow are really edible."

Ji Ling froze for a moment.

"I recently taught the chapter on biodiversity to grade 11. This chapter is really boring, so I thought about growing some real mushrooms, so that I can catch up with the section on fungi two weeks later." Sui Cannong said , "But you have seen the flowers in my room, I am somewhat overwhelmed now."

"So I wanted you to help me." He said, "Mr. Ji, can you come to my classroom a few more times to help me grow these mushrooms?"

Sui Cannong slightly emphasized the three words "well".

Sui Cannong bought one or two such potted mushrooms before, and planted them at home for fun. They can indeed produce a lot of mushrooms, which are quite fresh, but Sui Cannong still prefers green plants with leaves.

However, Sui Cannong took advantage of his lack of class this afternoon, and went directly to the market to buy a large pot of mushroom bags, and came back with a total of five different types of mushrooms.

Because he wants to find a sustenance for Ji Ling, or a task, in short, it must be something that can hang him and support him to live for a while.

Although the growth cycle of mushrooms is a little shorter, Ji Ling said that he loves to eat mushrooms, so Sui Cannong thinks this should arouse his interest.

Sui Cannong saw Ji Ling lowered his head and stared quietly at the fungus bags for a long time, he knew that he should have taken the right step.

A few seconds later, Sui Cannong heard Ji Ling say, "No problem."

"But Teacher Sui, I haven't raised mushrooms before." Ji Ling added hesitantly, "I'm afraid I might spoil it for you..."

Sui Cannong quickly interrupted him: "It's okay, it's actually very easy to raise."

Sui Cannong directly took out a stack of post-it notes. He first wrote "Mr. Sui" on one of them, and pasted it on the rose flower pot.

Then he wrote "Mr.Ji" on another one, and pasted it directly on the plastic basin where the fungus bag was placed.

"One fungus bag can produce mushrooms twice. If the growth is successful, the first round will be used by the students." Sui Cannong smiled at Ji Ling, "We can eat the second round together."

"Fungus likes tides and needs watering every day, so I may trouble you to come here every day." He said.

In fact, if Ji Ling thinks about it carefully, he will find that the logic in Sui Cannong's words is actually very strange.

Because watering doesn't take much time, Sui Cannong can easily spray the mushrooms while watering other flowers and plants.

But Ji Ling didn't notice this, because Sui Cannong was very sincere at this time, and he looked like he really needed help.

Besides, what Sui Cannong said just now was "watering every day", which means that he can come to Sui Cannong's classroom every day. Ji Ling feels that he has no reason to say "no".

Ji Ling raised her face and said seriously to Sui Cannong, "Okay."

Sui Cannong stared into Ji Ling's eyes for a while, and said for a while, "If you promise, you must do it."

Ji Ling was a little dazed, because it was just watering the mushrooms, but Sui Cannong's expression was very serious, as if they were talking about a very important event.

But maybe Sui Cannong really cares about his students.Ji Ling thought, so he hoped that the mushrooms would grow better so that students would be more interested in the class.

So Ji Ling nodded and said, "I am a person who keeps my promises, and I will do it."

Sui Cannong finally let out a breath.

The growth cycle of mushrooms is about two weeks. If there are two rounds of mushrooms, it will take about a month.

He thought, at least for this month, people should be safe.
