[Christmas is great, although I don't know who Jesus is - by Leeds's harem group]

As autumn turns to winter, Hogwarts School of Witchcraft and Wizardry has been sprinkled with a thick layer of white frosting, and wizarding apprentices have changed into winter uniforms with better warmth.

During this period of study, Zhang Jing and others, who have the 'exchange student treatment', learned all the spells from the first to the third grade through cross-level course selection, and mastered the spells such as immobilization spells, lock picking spells, petrification spells, stop spells, disarming spells, and floating spells.

Sounds like you'll be graduating in a year? Unfortunately, the Charms course at Hogwarts only teaches "basic spells", and there are quite a few spells that students need to learn through various sources, some need to be found in the library, some need to be bought in the bookstore, some need to be learned from the wizards who cherish the broom, and some need to join special organizations...... For example, the Phantom Shifting Charm, the Patronus Charm, and the Avada Suo Spell, which they considered to be required magic, seemed to have to rely on Liz's 'face' to teach.

Taking 10,000 steps back, there are many things in the wizarding world that they can learn from them, in addition to "magic spells".

"I said, Ninth Sister, is it really okay?" Zhang Jing, Liu Mengli, Ying Yue, and Lian Xing all stared at the green boiling liquid inside the crucible with vigilant eyes, and they remembered clearly that the juvenile potion they drank was not this color.

"How can there be a problem, Sister Jing, who do you think I am?" Murong Jiu glanced at his cousin angrily, as the only person in the team who had taken Snape's Potions class, she had infinite confidence.

“…… However, you've only been studying for four months, Ninth Sister......" Zhang Jing muttered.

Hearing this, Murong Jiu raised his eyebrows, "Unless you are willing to continue to use this body to go shopping and spend the entire Christmas holiday like this, you still have to drink my potion afterwards." ”

That's right, it's not a potion that turns back into an adult, so you can remove the ailment by switching to the MC system. The question is what happens when you become an adult again? They couldn't continue the course with the body of an adult, so they could only rely on Murong Jiu to configure the potion of 'turning into a child' by himself.

Fortunately, by handing over the recipe of Yitong Chinese medicine and the finished product of the elixir, Murong Jiu finally gained Snape's trust and obtained the configuration method of various powerful potions, including this potion.

"The last step is to put on the earmuffs I put on the bed, and the sound of the mandrake will hurt people." Murong Jiu himself took out a fluffy earmuff from the backpack space and put it on for himself.

"I've heard of this grass too! The cry of a ripe mandrake is deadly! Zhang Jing, who routinely chooses red earmuffs, wears them firmly.

"That's just the wizard of this world, how can we be lethal if our HP, resistance, and equipment are there?" That being said, Murong Jiuke had never taken off his earmuffs to listen to this thing. If she did that, what difference would she have from the idiot Xianggong who ran up to her house to eat the Avada Death Curse?

"Are you ready?" Murong Jiu grabbed a cluster of plants with purple-green leaves, paused for a few seconds, and then pulled it out vigorously.

(Whoa, whoa, whoa——!!! ）

Murong Jiu pulled out not a root, but an ugly baby-like stem covered in mud, with leaves growing on top of its head. The baby's skin was mottled pale green, and from the vigorous movement of its lungs, it could be inferred how it was cursing Murong Jiu.

"......" Even with earmuffs, a little scream could be heard, Murong Jiu frowned, cut off a baby-shaped stem with a special knife, and then stuffed the mandrake back into the dirt.

"Disgusting plants." Ying Yue coldly commented that if there was such a thing in her Flower Shifting Palace, she would probably blow up the entire palace.

"It's good to be useful~" Murong Jiu took off the earmuffs, smiled and disposed of the cut things, and then put them into the flask next to him for processing.

“…… Ninth sister, you look like you now, you really look like the bad witch I watched on TV before. Zhang Jing couldn't help but say.

"Hey, who am I trying to potion for!"

[Get out of the Christmas holidays, I just want Hogwarts to have classes all year round - by Draco Malfoy]

It's hard to tell the cultural boundaries between wizards and Muggles, it's like "Christmas", it's obviously a Muggle Catholic holiday, wizards should worship "Merlin" instead of "Christ", why celebrate the birth of Christ, and celebrate the birth of Merlin...... Unless the two people's birthdays are on the same day.

Well, in any case, similar to the Muggle world, the wizarding world has a Christmas holiday from December 24th to January 6th. Students can choose to go home, they can choose to travel together, they can choose to stay in school for some of the smaller celebrations on Hogwarts, or they can go shopping in the Muggle world like the loli above—it's a holiday that students love to see.

Presumably, only Draco Malfoy would want to cancel the Christmas break......

"I'm sorry~ I'm going to go to Yanan for a walk, I can't accompany you to Diagon Alley to play~" Liz passed the time with a group of schoolgirls on the platform.

"Yanan......?" A girl from a Muggle family asked, tilting her head.

Another girl from a wizarding family obviously knew more about the wizarding world, and when she heard this, she covered her mouth and exclaimed, "Well, isn't it called a 'crazy place', and outsiders are not allowed to enter?!" ”

Liz smiled and shook her head, "This statement is not accurate, the Ministry of Magic is 'prohibiting people from going to Yanan for medical treatment' but 'encouraging wizards to go to Yanan to hunt monsters', because the monsters inside sometimes rush out to cause casualties, and someone still needs to deal with them." ”

"Monsters, monsters?!" Obviously, even this girl from a wizarding family only knew that 'you can't go to Yanan', but the parents didn't explain why you can't go to Yanan.

"Isn't that dangerous? Professor Leeds, don't go. The girls were worried.

"That's not good, the old Taoist priest who taught me the immortal art of the East said that the duty of a Taoist priest is to kill demons and eliminate demons, punish evil and destroy evil, even if we have countless souls in our hands, rivers of blood flowing under our feet, and bones behind us, we must protect the weak." This is true as it is.

"Professor Leeds is so handsome~~!" The girls clapped vigorously.

“…… And what about Malfoy-san? Finally, a girl asked curiously about Malfoy, who was petrified behind Leeds.

"He? …… Who lent me a wand. Liz picked one of the girls who were eager to pull out their wands and pointed at Malfoy, "Stop." ”

"No, please leave this sacred task to Harry Potter, he is the savior! I don't want to go to Yanan to fight the werewolves! Malfoy turned and fled, crying out in mourn.

"It's all petrified." Liz added another petrification spell, and he also had a lot of skills when he came to this world, even though these skills were visually ineffective against strong enemies, "Well, that's it." ”

"Ah...... Haha...... "Although not many people like Malfoy, at this moment, everyone feels pity for him.

"Yes, the wand will be returned to you...... By the way, even if you want to run away during the battle, remember not to be completely ignorant of attacks from behind like Malfoy~ Look for the opportunity to roll over, and you may be able to dodge the fatal blow. "Leeds is still continuing her 'Wizard Simulation Professor' tone.

"Yes~" The girls replied one after another.

The whistle of a steam train is heard.

"The train has arrived, I wish you all a happy holiday~" Liz waved goodbye to the girls, and then said hello to Remilia, who was reprimanding Red Meiling who had bought a large bag of snacks in the distance, before turning around and walking towards Malfoy, who was in a petrified state.

Lifted him up, "Really, you're the man who will hunt the Death Eaters in the future, how can you confess in front of just Yanan?" ”

"......," Malfoy said he had never thought of hunting Death Eaters!

"Okay, in order to change your weak personality, I'll try to transform you into a physical wizard. When you get back, ask Deng Lao to see if there is any magic that works well in melee combat! ”

"...... why wizards should fight in close combat, Malfoy can't understand!

"Well, a berserker who doesn't want to be an archer is not a good wizard! It's so happily settled~"

I don't understand the phrase "......" at all!
