The ceiling of the Great Hall at Hogwarts has always been a reflection of the weather outside the castle, something that Hogwarts students have always known that it can have dark clouds. Pen ~ fun ~ pavilion www.biquge.info can have lightning, and even stars. But—"What's going on with this sun?" A Ravenclaw boy asked, pointing to the 'sun' in the night sky above the ceiling.

Dumbledore stood up from the faculty and put his wand to his neck, "Everyone, be quiet, there is only one thing to announce today, the school board has unanimously decided to grant Mr. Field Diggory, a second-year Hufflepuff, a Hogwarts Special Reward Fund of 100 Kinaron to encourage him to invent this 'artificial sun'. ”

"Phew—" At the long table below, the students of the four houses were discussing fiercely, and many of them were pointing at the Hufflepuff long table.

"Oh, Field, you're in the limelight again. Ernie sat down on Field's right hand, put his arm around his shoulder, and said.

"I'd rather not be in the limelight, those guys from the school board asked me for the formula for the 'artificial sun', and I gave them no problem, but the key to the 'artificial sun' is not only magic, but the most important thing is to need Xiaoxi's blood, Lucius Malfoy's bastard actually dared to hit Xiaoxi's idea, I really want to give him a punch. Field said fiercely.

'Artificial Sun' is a large toy made by Field for Xiaoxi, Xiaoxi likes the sun, likes sunshine, but the bad weather in Britain is cloudy almost 200 days a year, especially during this time, it has been raining every day since April, Xiaoxi has been listless, so Field has an idea to create an 'artificial sun' for it.

The 'Artificial Sun' looks very high-end, but after Field's reading of the book "As Long as There Is a Wand, There Is a Way", and being reminded by Cedric for a sentence or two, he also had a new idea, and it was logical to make it, of course, Field's miscalculation of the amount of mana required and almost blew up the entire basement floor of the castle, so don't worry too much.

"Ignore him, Field, that guy has always been self-righteous, so I don't have much to do with the Malfoys, although Draco's grandmother and my grandmother are cousins. I've heard that the other twelve trustees on the board are now interested in removing Lucius Malfoy," Ernie said, pouting.

The population of the wizarding world is actually small, so in the pure-blood family, it is normal for there to be blood relations, Ernie and their Macmillan family is a pure-blood family with a long history, and it is normal to have a relationship with the Malfoy family, Field has always felt that if he carefully flips through the family tree, he can find practice with the Malfoy family, but this does not prevent Field from wanting to beat Lucius Malfoy's idea.

"If it were possible, I'd like to beat Draco Malfoy together. Field watched as Draco Malfoy and his two younger brothers were walking towards him with a smirk.

"Diggory, it's said that you made this sun because you cry and call out to your mother when you sleep at night, right?" Draco Malfoy whispered.

"Malfoy, look at your pathetic wretch, what are you going to do but tell people that your dad is Lucius Malfoy? "Field didn't bother to talk to him.

"Why? You envy it? My father is Lucius Malfoy, which makes me proud, should I hide it? The honor of the family is not known to others, is it worthy of enjoying the fruits of the struggle of my ancestors?" Draco Malfoy looked as a matter of course.

Field was a little curious, but when he saw Ernie nodding in agreement on the side, he also realized something. In the wizarding world and the Diggory family, such low-key pure-bloods are actually very rare, and unlike the East, many noble children are obliged to contribute to the spread of family glory when they enjoy the inheritance of their ancestors. So it's understandable that the pure-blood family talks about the family all day long.

"Well, since you care so much about the glory of the Malfoy family, don't be embarrassed here, if I can't help but turn you into a bed bug, then you'll lose all the face of your Malfoy family. Field threatened him well, packed a few things, and prepared to visit Rolf.

Draco Malfoy's face grew more and more ugly as he looked at Field's back in the distance, and he wanted to draw his wand and give him a curse, but he didn't dare, yes he didn't. He knew that he was far from Field's magic level, and even a sneak attack might not be successful. If he attacks Field first in full view of everyone, it will be fine if he succeeds, but if he fails, Field's guy may kill him. Draco Malfoy actually knew Field very well, this good old man in the eyes of the whole school, and good students actually had a violent side, which he had seen last year.

Field walked briskly to the Hufflepuff common room, where he was going to bring Rolf something to eat, and Rolf had been sick this holiday, albeit just a common cold, but also on bed rest.

"Rolf, brought you bread, potatoes and beef patties. How are you. Field asked, placing food on Rolf's bedside table.

"It's okay, I've slept for a day, it should be almost fine, help me get the yellow bottle in the box under the desk. Rolf said to Field as he got up to eat.

Field opened the box and managed to find the yellow bottle in the whole box of bottles. "Rolf, when did you get so many potions? ”

"I've been practicing potions making for two months before school starts this year, and my grandfather and Professor Kettleburn also gave me a lot of potion materials some time ago, so I started practicing, so I have a lot of stockpiles. What's wrong?" asked Rolf, nibbling on the beef patty.

"You can sell them all for some pocket money, and it's a waste to put them here. Field said as he flipped through Rolf's work.

This is a chest that has cast a space expansion spell, and there are at least three or four hundred bottles of potions inside, many of which are high-quality, and the quality is first-class. Field had to lament Rolf's level of potions.

"Oh, then you sold them for me, just keep a little of everything. Rolf said nonchalantly.

"Leave it to the Bans brothers in Hogsmeade to deal with it, it will be quick. What is this bottle?" Field, picking up a small black vial, which had no label on it.

"Oh, this, when you were working on that 'artificial sun' in the past two days. I made it myself, using the juice of the dragon's head fruit, and those No. 3 mercury gold solutions of yours. Rolf sat up excitedly.

"What failed experiment?" The No. 3 mercury gold solution was a failure product produced by Field when he first made the raw material for the 'artificial sun'. "What the hell is this?"

"I call it the Mana Activation Solvent, and when used as an additive to magic items, it can extend the duration of mana. Rolf stopped eating and explained his invention to Field.
