A day at Hogwarts

The day of the Quidditch match came, and the rain continued to fall, and even tended to get heavier.

At breakfast time, the members of the Gryffindor Quidditch team sat together, and Wood checked the breakfast on each team member's plate with a recipe he didn't know where.

In the past week, Wood asked the players to eat as much as Charles and eat extra bread to reserve physical strength.

The weather today is very, very bad. The game will consume more physical energy, so you must have enough breakfast.

So Harry finished the salty porridge, fried eggs, a few slices of toast with jam, two bananas and a bottle of happy water that had loosened the cap last night to release carbon dioxide.

He was familiar with this kind of breakfast and already knew where Wood's recipe came from.

Wood was very nervous and had no appetite, but he still forced himself to eat his share of breakfast.

Charles was eating baked white kidney beans with tomato sauce, bacon and hash browns leisurely. Next to him, Seamus asked him: "You're not going to the game today?"

In Simo's memory, it seems that Charles has never appeared on the court.

Charles shook his head slightly and said, "I won't go. There are still many things to be busy in the greenhouse."

After breakfast, the wind and rain became stronger and stronger. The umbrellas in the hands of several students were blown away by the wind, and they became drowned rats in the blink of an eye.

Such heavy rain could not dampen the enthusiasm of teachers and students in the school for Quidditch. Almost everyone headed to the stadium despite the wind.

In the locker room of the stadium, the players changed into their uniforms. Harry adjusted his clothes with the Iron Armor Charm on them, and touched the amulet hanging around his neck that Charles gave last year, hoping that he would not need it today.

Wood was very nervous and wanted to say something encouraging, but after a few mouthfuls, nothing came out.

The door to the locker room was opened, and a red-haired head stuck in.

"Ginny?" Fred saw his sister poking her head, "What are you doing here?"

Ginny blushed slightly and replied, "I'm here to find Harry."

She walked into the dressing room, came to Harry, stretched out her hand and said, "Take off your glasses quickly and hold them in your hand."

Harry didn't understand what Ginny was going to do, but finally did it.

Ginny waved her wand, tapped her glasses one last time, and recited the incantation: "Invulnerable to fire and water!"

After the spell was completed, she said to Harry: "Your glasses are not afraid of rain anymore. I just tried it on Charles's glasses and it worked."

"Great!" Harry put on his glasses happily, feeling more clearly than before.

At this time Fred said jokingly: "Oh, that's a good idea."

George continued: "It's a pity that we don't have glasses, so we can't ask my sister to help."

Ginny turned to them and said, "I could put a spell right in your face!"

It turns out that this curse can be applied directly to the face. When the Gryffindor team members walked into the stadium in the wind and rain, they found that the effect was quite good.

The students in the audience cheered despite the rain.

"Huh?" Seamus suddenly realized that there was one less person on Gryffindor's side, "Where's Granger?"

It was normal that Charles didn't come, but Hermione didn't see anyone either, which was a little strange.

In the last row of the Slytherin House auditorium, no one noticed Hermione wearing a cloak hiding behind everyone.

Meanwhile, Charles was busy in the greenhouse.

It has been nearly two months since the planting experiment began, and the latest soil test report has come back and needs to be classified and stored.

There are 5 newly moved cabinets in the office area of ​​the greenhouse. Each cabinet has 4 layers. Each layer contains 4 file boxes. There is one layer for each of 18 kinds of plants. There is one box for each of the 4 fertilization methods for each plant. There are two more boxes. The first layer contains documents such as attendance records and purchase lists.

Charles arranged the soil test reports by number, opened the corresponding box, sandwiched the new report with the old report, and started to look through it after sorting it out.

According to the conclusions drawn from last year's Chinese biting cabbage planting experiment, chemical fertilizers increase the upper limit of the blue bar of magical plants, and magic fertilizers are responsible for replenishing the blue bar.

Now that there is more data, it is more obvious that the two functions complement each other.

In the soil of plants where chemical fertilizers and magic fertilizers are applied at the same time, nitrogen, phosphorus and potassium are consumed faster than in the soil of plants where only chemical fertilizers are applied. Now the gap has begun to widen, and it is estimated that the gap will be even greater in the future.

"Are you encountering any problems?"

When Dumbledore came over, he found Charles looking sad and troubled by something.

He attaches great importance to the experiments here and comes here from time to time to take a look and solve some problems.

Charles replied: "I found there was a lack of precise methods for measuring the active ingredients of dragon manure compost in the soil."

Now it is found that the absorption of chemical fertilizers by plants increases when mixed fertilization is applied, so does the absorption of magic fertilizers also increase?

Theoretically, it should increase, but there is a lack of precise measurement methods and it is impossible to draw conclusions based on data.

Dumbledore understood what Charles meant, thought about it for a moment, and said after a moment: "This problem will be encountered in determining the efficacy of herbs and potions. You can ask Snape for advice."

The more magic ingredients in the same herb and potion, the better the effect and naturally the more valuable they are, so a method for measuring the magic content was developed.

Charles believed that Dumbledore must know this method, and he would definitely use it when he was studying the uses of dragon blood. However, he did not tell him and asked Snape to consult him, probably because he wanted to ease or even eliminate the conflict between the two.

So Charles didn't respond to Dumbledore, thinking that wouldn't it be better to ask the potion masters in the Himalayas through Lupine's channel of feedback on werewolf potions, and maybe he could use this to formulate a unified standard for the world.

The greenhouse suddenly became quiet. Charles was concentrating on flipping through the forms. Dumbledore also opened other file boxes to study the data inside. There was only the "crackling" sound of raindrops hitting the greenhouse, and occasionally the cheers from the Quidditch pitch could be heard. sound, and dull thunder.

After sitting on the chair for a long time, Charles stood up and moved around. He came outside the greenhouse door, took out a bottle of Happy Water, took a few sips, and looked towards the Quidditch pitch.

The rain was so dense and blown askew by the wind that the two Seekers flying above the pitch could barely be seen.

Charles saw Piedan quietly crawling out of the forbidden forest and crawling towards the court, looking up and around from time to time.

Piedan found a person standing in front of a greenhouse door. Not sure if he had seen him, he immediately ran away and rushed into the Quidditch pitch.

Charles just smiled and continued to go back to the greenhouse to look at the data after drinking a bottle of happy water.

"Is it starting to get dark?"

After an unknown amount of time, Dumbledore noticed that the surrounding light had dimmed.

He stood up, moved about, and asked Charles: "Who won on the other side of the court?"

Charles shrugged and said, "The game isn't over yet."

Dumbledore was not surprised. It would be difficult to find the Snitch in such weather.

"Huh?" He suddenly discovered something and hurriedly walked out.

Charles also followed out and found a large group of dementors flying towards the stadium from the direction of the Forbidden Forest.
