Roaming the universe, all thanks to your many dark skills!

After the snap of their fingers, the scenery before the three people's eyes was completely different from before.

"Where is this..." Luo Youwei was startled at first, then after seeing the furnishings around her clearly, she exclaimed, "Let's go home."

"Thank you, Uncle Luo. I'll go back first." Hermione was also eager to go home at this time, and said to Luo Youwei: "I'll come to play with you later."

Having said that, he left in a hurry.

"How is your learning of the Traceless Stretching Spell going now?" Rosen asked.

"It can only expand to half a cubic meter of space." Luo Youwei scratched her head helplessly and said, "It seems that my idea of ​​putting Mount Sumeru into the mustard seed is hopeless for the time being."

"You are really bold." Rosen said, "Show me your study notes."

"Dad, take it yourself." Luo Youwei threw the cloth bag to Rosen, then rushed out of the house cheering.

At this time, there was white snow everywhere outside. She couldn't help but feel playful, so she found a shovel and started making a snowman.

After Rosen casually threw out a fireball to ignite the wood in the fireplace, he sat beside the fire and looked through Luo Youwei's notes.

Studying is not shabby.

Luo Youwei's notes are very detailed and highly extensible.

Because it not only involves what she learned in class, but more importantly, it also records the magic she learned outside of class.

To be honest, this is no longer a simple lecture note, but more like a study note. It is certainly very useful for Rosen who wants to learn magic by himself.

So when he carefully read the study notes in his hand from beginning to end, he received the prompt message he had been waiting for.

"After careful study, you have mastered a new skill: the Traceless Stretching Spell."

"The Traceless Stretching Spell can expand the internal capacity of an item without damaging its appearance, while reducing the weight of the item placed in the space, making it easier to carry.

Current level LV1, after successful casting, the internal space of the container will be expanded by an additional 50%. If the spell fails, there is a certain chance that the item will be damaged or even disappear. "

Rosen casually pointed at a glass teacup on the table and activated his skill.

"Spell cast successfully, proficiency +3."

Rosen took the glass and saw that the capacity inside had indeed increased by 50%. So he put it on the table and cast the spell again.

With just a click, the glass shattered into a pile of glass shards on the spot.

"The spell failed, the item was damaged, and the proficiency was +1."

Despite this, Rosen felt that this magic was extremely useful and had already begun to think about how to raise its level as quickly as possible.

Luo Youwei had just built a rough snowman in the yard when Hermione came running over from next door to help.

Mr. and Mrs. Granger also came with gifts to thank Rosen for taking care of Hermione.

When Mr. Granger saw that there was no Christmas tree in Rosen's living room, he immediately and enthusiastically offered to accompany him to buy the best one.

To be honest, Rosen has no interest in Christmas, but now living in the UK, of course he has to adapt to the local customs.

So he drove with Granger to buy a Christmas tree, put it in the living room and decorated it a little, and immediately there was a festive atmosphere.

In the evening, Rosen prepared a big meal. The father and daughter ate happily, then washed up and went back to their rooms to sleep.

After turning off the lights, Rosen did not rush to sleep. Instead, he took out a pile of socks and began to practice the Traceless Stretching Spell with them over and over again.

To be honest, Rosen's spellcasting success rate is actually not low.

But the problem is that simply expanding the capacity by 50% is not what he wants, so he has to cast the spell again on the socks after the expansion.

As we all know, the success rate when strengthening items often drops at an alarming rate, and this is the situation Rosen is facing now.

As a result, each sock failed to survive the second round of expansion.

However, his death was worthwhile, as it at least contributed 1 point of proficiency to Rosen.

After the wall clock in the room rang eleven times, Rosen got the system prompt he wanted.

"After diligent practice, your Traceless Extension Spell has been upgraded to Level 2. If the spell is successfully cast, the internal space of the container will be expanded by an additional 100%. If the spell fails, there is a certain chance that the item will be damaged or disappear."

Rosen continued to cast spells on the remaining socks, and soon found that the success rate was slightly higher than before, and even the success rate of the second round of expansion was improved.

It was not until one time when Rosen successfully expanded the capacity of a cotton sock three times, reaching eight times the original capacity, that he stopped.

He took out the Nimbus 2000 that he had secretly bought when he first went to Diagon Alley and put it into his socks.

"Good night, my dear girl, have a sweet dream." Rosen said lightly: "Merry Christmas."

As he spoke, he lightly tapped the socks with his fingers and released the skill.

The next moment, a soft white sock appeared on the head of the bed where Luo Youwei had already fallen asleep.

The next morning.

Rosen was cooking in the kitchen when he heard Luo Youwei's scream of surprise.

"Wow, it's the Nimbus 2000, oh my god!" Luo Youwei didn't even have time to put on her shoes, she rushed to the kitchen barefoot with the Nimbus 2000 in her hand.

After giving Rosen a hug, he smiled and said, "Dad, you are awesome! How did you know I always wanted it?"

"Of course." Rosen said with a smile, "I'm your father, so I know everything. As soon as I see your sad face, I know what's on your mind."

"Thank you, Dad." Luo Youwei said with a smile.

"Let's make this clear first." Rosen said, "You can have fun, but safety comes first. Now put on your shoes, and then come over for dinner."

"Yes sir." Luo Youwei saluted him and then ran back to put on her shoes.

"Weiwei, are you going to stay home or go out with me?" Rosen asked casually during the meal.

"Where are you going?" Luo Youwei asked casually while lowering her head to eat.

"Diagon Alley." Rosen said, "I have to go to Ollivander's Wand Shop to see if he has finished my battle staff."

"What if it's not done well?" Luo Youwei said with a smile on her face.

"Then I have to consider whether to take down his golden signboard." Rosen said half-seriously.

"Dad, I've decided to go with you." Luo Youwei smiled and said, "If you really fight with Ollivander, I can cheer for you."

"Shouldn't you rush over to help?" Rosen asked with a frown.

"Dad, I'm a girl!" Luo Youwei looked down at her slender fingers and said tenderly.

Before she finished speaking, she couldn't help shivering.

Rosen also got goosebumps all over his body and said, "Don't talk so teasingly in the future. This is not your style. It's too annoying."

"I understand." Luo Youwei felt so disgusted that she agreed readily.

After dinner, Luo Youwei washed the dishes, and the father and son drove out directly.

Rosen is not a wizard from this world, and does not mind using "Muggle items" such as cars. And because he is not a real wizard, the Ministry of Magic can't do anything to him.
