Lynn was so excited that he pulled out the envelope from beneath the three grenades with trembling hands and opened it.
Inside was a personal letter from Professor Green.
"I heard about what happened on Halloween. I thought it wasn't very safe for you to be at Hogwarts Castle, and a gun didn't seem enough for you to defend yourself, so I sent you some self-defense weapons from the Muggle world. I hope you can use them reasonably to protect your safety."
After reading Professor Green's signature at the bottom of the letter, Lynn's lips twisted in surprise.
Self-defense weapons...
Are you calling the Mk2 grenade a self-defense weapon?!
Lynn still had some knowledge of modern weapons. For example, the three Mk2 grenades in front of him, shaped like pineapples, were filled with nitrostarch compound and a certain amount of TNT explosives. The kill radius after the explosion is five to ten yards, and including the distance of the shrapnel ejected, the death radius could reach up to fifty meters!
Unlike the magic spells cast by wizards, even if a wizard casts a silent, wandless spell, the light emitted during its flight will still attract the enemy's attention and vigilance.
However, the Mk2 grenade doesn't make any movement during the throwing process, and the faint sound it makes when the pin is removed can be silenced by magic.
Therefore, if you encounter an overwhelming enemy, using Mk2 grenades to buy time and escape is an excellent option.
"Thank you very much, Professor!"
Lynn put the three grenades away. As an alchemist, the power of the grenades alone wasn't enough. He planned to enhance their power through the alchemy circle.
It seemed he had been quite busy these days!
Lynn rubbed his temples. He also planned to relax a bit more during the Christmas holidays.
…
On the other side, in the Gryffindor girls' dormitory.
Irina was opening her Christmas gifts. Since her parents were Muggles and couldn't use owls to send gifts to Hogwarts Castle, she had to wait until the summer holidays to receive her presents from them.
She was alone in the dormitory at the moment, as her three roommates, including Hermione, had already gone home for Christmas.
"These two unreliable ones aren't home with me for Christmas. They said they'd been in the two worlds and left me alone at Hogwarts... Sigh, I still don't have sweet, gentle Hermione to keep me company. I'm so lonely..."
Irina's face filled with resentment.
The three Christmas gifts on top were from three professors, and their contents were exactly the same as the ones Lynn received last year.
"Snape isn't bad, but he should just drink this happy potion himself. People just need to smile more!"
After taking the joy potion given by Professor Snape, Irina chuckled to herself.
Irina opened another cylindrical gift. Inside was a jar of cookies, sent by the Weasley twins.
"Fred and George gave it to me... There shouldn't be any problem, right?"
Irina eyed the cookie in her hand suspiciously, but in this timeline, hadn't the Canary Creams still not been invented?!
After much deliberation, Irina finally closed her eyes and ate the cookie.
Bang!
The next second, a white puff of air slowly rose, and Irina turned into a cute canary.
The canary seemed to be angrily chirping, and the entire dormitory was filled with loud tweets.
Bang!
After a minute, the Canary Cream's effect wore off, and Irina returned to her normal appearance.
"Fred and George!"
Irina gritted her teeth and clenched her fists, determined to give them a powerful lesson.
During the time she was a canary, she finally understood why the Canary Creams had appeared so early.
Recalling the alchemy topic discussed by Major Rohr and the Weasley twins when they met outside the castle, Irina could guess that they had learned alchemy in advance.
That Major Lynn... could he be a reincarnator like me?!
Otherwise, why would he be able to change the Weasley twins' alchemy learning process?! Also, he had appeared during the troll incident.
Irina thought, but she still couldn't determine the identity of the other person.
After all, what if there was a major in the original book, and that person saw Harry and Ron defeating the troll but didn't intervene?!
It's clear that everything Irina had done had significantly changed the troll incident, and naturally, what happened afterward would be different.
At that moment, Irina looked at the three remaining gifts, which were from Harry, Ron, and Hermione.
Harry gave her a broomstick model, Ron gave her a magical chess set, and Hermione gave her a large bag of Chocolate Frogs.
Irina carefully treasured the Christmas gift from her friend, took a Chocolate Frog from the large bag, and popped it into her mouth.
In the Gryffindor boys' dormitory, Harry was also trying on his ancestral Invisibility Cloak.
This was a silvery-gray garment, almost liquid-like. It felt as though it were woven with water and was very strange to the touch.
Unlike the Invisibility Cloak that Lynn used as a decoration, Harry's ancestral Invisibility Cloak was one of the three Deathly Hallows. It was said to be able to evade death.
Of course, the idea that the Invisibility Cloak could evade death might be somewhat exaggerated, but its well-known advantage was its permanent invisibility, unlike market invisibility cloaks, which had an expiration date.
It could be said that the Christmas feast was the most sumptuous banquet of the year at Hogwarts.
On the long tables of the four main houses, you could see a hundred roasted turkeys, heaps of roasted meats and boiled potatoes, large platters of delicious sausages, bowls of peas mixed with butter, and rich, thick gravy and cranberry sauce.
Every few steps along the long tables of the four houses, magical firecrackers appeared. These firecrackers were very magical. Harry and Fred set off a firecracker that exploded like a cannon shot, enveloping everyone in a cloud of blue smoke while making the hat of a vice-commander explode, along with several animated white mice.
These colorful firecrackers were like mystery boxes, which intrigued Irina so much that she barely ate much at the Christmas dinner. Instead, she opened nearly a hundred colorful firecrackers.
As the guest of honor, Professor Dumbledore changed his pointy wizard hat for one decorated with flowers. Professor Flitwick had just told him a joke, making him smile happily.
Irina and the others watched Hagrid take glass after glass of wine, his face becoming redder by the moment, and he finally kissed Professor McGonagall on the cheek. To Irina's surprise, Harry and Ron, Professor McGonagall actually laughed, blushing and tilting her tall black hat aside.
Hagrid is incredible!
Irina thought to herself.
As Harry, Ron, and Irina left the table, they were still holding many things that had exploded with the colorful firecrackers, including several snacks from Honeydukes and small toys like the magical chess set.
Ron also regretted that his gifts hadn't been properly delivered, because there were so many firecrackers in the magical chess set and other colorful packages.
