Chapter 333: Waterproofing Glasses

The day of the Quidditch match has arrived, and the rain is still falling, and it is even getting heavier.

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

In the past week, Wood asked the players to eat as much as Charles, and to eat more bread to reserve energy.

Today's weather is very, very bad, and more energy will be consumed in the game, so breakfast must be enough.

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 the lid loosened last night to release all the carbon dioxide.

He was very 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 breakfast.

Charles ate baked white beans in tomato sauce, bacon and fried potato cakes slowly, and Seamus next to him asked him: "Aren't you going to watch the game today?"

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

Charles shook his head slightly and said, "No, there are still many things to do 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 extinguish the enthusiasm of all teachers and students for Quidditch. Almost everyone went to the stadium against the wind.

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

Wood was very nervous and wanted to say something encouraging, but he opened his mouth for a few times and still couldn't say anything.

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

"Ginny?" Fred saw his sister looking out, "What are you doing here?"

Ginny's face flushed slightly, and she replied, "I'm here to find Harry."

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

Harry didn't understand what Ginny was going to do, but he did it in the end.

Ginny waved her wand and tapped her glasses, chanting the spell: "Water and fire are invulnerable!"

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

"Great!" Harry put on his glasses happily and felt clearer than before.

At this time, Fred said jokingly: "Oh, this is a really good idea."

George took over: "It's a pity that we don't have glasses and can't ask my sister for help."

Ginny turned around and said to them: "I can cast the spell directly on your face!"

It turned out that this spell can be cast directly on 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 in the rain.

"Huh?" Seamus suddenly found that there was one less person on the Gryffindor side, "Where is Granger?"

It's normal that Charles didn't come, but Hermione was also missing, which was a bit strange.

In the last row of the Slytherin College audience, no one noticed that Hermione, wearing a cloak, was hiding behind everyone.

At the same time, Charles was busy in the greenhouse.

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

Five new cabinets have been moved into the office area of ​​the greenhouse. Each cabinet has four layers, and each layer contains four file boxes, one layer for each of the 18 plants, one box for each of the four fertilization methods for each plant, and two extra layers for documents such as attendance records and purchase lists.

Charles arranged the soil test reports by number, opened the corresponding boxes, put the new report and the previous old report together, and started to look through them after sorting them out.

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

Now with more data, it can be more clearly seen that the effects of the two are complementary.

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

"Are you having any problems?"

When Dumbledore came over, he found that Charles was frowning and was troubled by something.

He attached great importance to the experiments here, and came to see from time to time to solve some problems.

Charles replied: "I found that there is a lack of precise method to measure the content of effective ingredients in dragon dung compost in soil."

Now it is found that plants absorb more chemical fertilizers when mixed fertilizers are applied, so does it also absorb more magic fertilizers?

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

Dumbledore understood what Charles meant, and thought about it aside. After a moment, he said: "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 efficacy, and naturally more valuable, so a method for measuring magic content was developed.

Charles believed that Dumbledore must know this method, and he would definitely use it when studying the use of dragon blood, but he did not say it and asked himself to ask Snape, probably to ease or even eliminate the conflict between the two.

So Charles did not respond to Dumbledore, thinking that it would be better to ask the potion masters in the Himalayas through Lupin's feedback on the werewolf potion. Maybe a unified world standard could be established based on this.

The greenhouse suddenly became quiet. Charles concentrated on looking through the table, and Dumbledore also opened other file boxes to study the data inside. There was only the "crackling" sound of raindrops hitting the greenhouse, and occasionally cheers from the Quidditch field and dull thunder.

After sitting in the chair for a long time, Charles stood up and moved around. He came to the door of the greenhouse, took out a bottle of happy water, froze it and drank a few sips, and looked towards the Quidditch field.

The rain was very dense and was blown sideways by the wind. The two seekers flying over the field were almost invisible.

Charles saw Pi Dan quietly crawling out of the forbidden forest and crawling towards the field, looking up and looking around from time to time.

Pi Dan found a person standing in front of the door of a greenhouse. He didn't know if he saw him, so he ran and rushed into the Quidditch field.

Charles just smiled, drank a bottle of happy water and went back to the greenhouse to look at the data.

"Is it getting dark?"

After an unknown amount of time, Dumbledore found that the light around him had dimmed.

He stood up and stretched himself, then asked Charles, "Who won on the court?"

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

Dumbledore was not surprised, as it was difficult to find the Snitch in such weather.

"Huh?" He suddenly discovered something and hurried out.

Charles followed him out and found a large group of Dementors flying towards the court from the Forbidden Forest.
