Dumbledore? He knows nothing about MC alchemy.

"uh-huh...................."

"........................"

"........................"

"Why are you still waiting here?" Dumbledore asked with some confusion.

"One hundred gold galleons is not enough." Kaisen said.

".....what did you buy from Remus?"

"Magic crystal."

"How big?"

"It's as big as a basketball..."

Dumbledore reluctantly sat up from his chair, put his hands behind his back and looked at the Forbidden Forest in the distance.

"A crystal the size of a basketball...that's how much he quoted you."

Kaysen recalled: "He held up five fingers."

"That's right, five gold Galleons, right?" Dumbledore turned and looked at Kaisen strangely.

The latter suddenly touched his nose in embarrassment.

"How much did you spend?"

"Fifteen Galleons?"

"Fifty Galleons...right?"

Kaisen remained silent, just touching his chin with his hand.

"Tell me, Kaisen. Forgive me, an old man, for not being able to guess."

"Emm...Five hundred gold Galleons."

Somehow, the look Dumbledore gave Kaisen was three parts weird, three parts helpless, and four parts pity.

Finally he took out a bag containing six hundred gold galleons.

"Forget the remaining two hundred gold galleons. I sincerely hope you'll find a bodyguard to go with you on this journey. Just consider it as helping an old man like me take care of my former students. How do you think?"

Kaisen packed up all the Galleons: "Of course... why don't you just give it to him?"

"He has a pretty fragile ego."

Chapter 68 Bodyguard Lupin

"How about this request?"

"Yes... I don't know if milk will work for him."

Kaisen nodded, walked out of the principal's office, and handed Lupin 180 Galleons.

"Please check it."

"No need, you are a professor at Hogwarts, I believe you...it's almost time for me to leave." Lupin smiled shyly, tightened his wizard robe and was about to leave.

"Wait a minute, Mr. Lupin, I need to travel around the world to look for magic crystals this holiday. Do you mind accepting a small commission, such as being my bodyguard?"

Kaisen took the remaining Galleon in his hand and weighed it. "It's very heavy."

"No, I think you should..." Lupin didn't care why the professor in front of him knew his name. He just refused subconsciously. Suddenly, a thin thread flew into his ear and slowly dissipated in his ear canal.

As the thread spread out, Lupin nodded naturally: "Okay, but the salary doesn't need to be too high, ten Galleons will be enough, but I need to manage the money along the way, this requires..."

Before he could even ask for it, a bag full of Galleons was thrown in his face.

"Ward? Be careful!" Kaisen subconsciously reached forward, trying to grab the bag of gold galleons to prevent the heavy object of four or five pounds from hitting the face of the bodyguard he had just found.

Then our bodyguard quickly reached out and took the bag of gold galleons.

"Oh... good skills. It seems you can do this job very well." Kaisen stood back and smoothed out the wrinkles on his body with some embarrassment.

"Speed ​​is of the essence in war, let's set off now. Come with me to a place first. It's a pity that my teleportation can't take anyone with me..."

"So how do we get there?"

"You are a student at Hogwarts, so you should know Hagrid. He has a..."

"No, can we not go to Hagrid?" Lupin said suddenly.

"Well... why? Okay, then you take me to Apparate. You know London, that's where we'll go." Kaisen said halfway and began to think that Lupin didn't have a good relationship with Hagrid at school.

But when he thought about how sloppy he looked at the moment, and that he might just be worried about losing face in front of his old acquaintances, he didn't say anything.

"I've been to London, but I can't recall the specific address."

"Does Baker Street know?"

"...I know. There was a detective there who was after me, and I'm kind of...well, interested in this address."

"Do you know his house? I'm his neighbor."

"Next door? 220 or 222?"

"222."

"Okay." The two of them said and left the area of ​​​​Hogwarts. Lupin held Kaisen's shoulders, and the next moment Apparition was activated, and the two of them appeared in the house at 222 Baker Street.

"Just sit anywhere... No, don't just sit anywhere yet. I have a difficult task for you. Go to Diagon Alley and buy two Z9 flying brooms. The money will come from the bag of Galleons I gave you. I need to make some strategies."

"I think one handful is enough."

"No, two!" A voice came from the garage, followed by the roar of an engine. Kaisen drove away from home, leaving Lupin alone.

Lupin looked at the priceless house in front of him and the bag full of gold Galleons in his hand, and shrugged helplessly.

"Dumbledore is right, letting this guy go around the world mining alone...tsk tsk tsk..." As he said that, he waved his wand, Apparated, and appeared in Diagon Alley in the blink of an eye. He put on the hood behind him on his head and walked towards a Quidditch supplies store.

Soon, he returned to 9 Baker Street with two Z222 brooms, but it seemed that Kaisen still hadn't returned.

He looked at the empty house in silence for a while, finally put the broom in the corner, patted his butt and sat on a long sofa that seemed to be for guests.

Not long after, Kaisen came back with a lot of self-heating food and water, which he put into his ender ring.

After walking into the house from the garage, he saw Lupin sitting on the sofa and sleeping with his head tilted back. He just walked over and pressed a button under the sofa, and the sofa turned into a bed.

After covering it with a blanket, he noticed the two brooms in the corner and took them upstairs to start modifying them.

The performance of the Z9 broom is not inferior to the Light Wheel series, and its straight-line speed performance is even higher.

The designer of this Z9 has no knowledge of ergonomics, and the broom handle he made is really abstract. Compared with the comfortable light wheel, it is like the difference between cruising and racing.

Of course the Comet and Sweep series are not involved in the discussion, that is the pedal.

However, the good thing about the Z9 is that most of the magic circuits are concentrated in the tail of the broom. Strictly speaking, the broom handle is useless. In fact, the entire marketing strategy of the Z9 is to buy the broom tail, and the broom handle is given away for free.

What Kaisen has to do at this moment is to replace the two brooms in front of him with more comfortable seats, speed instruments, magic navigation devices and handles to control the speed. The ordinary imitation racing car has evolved into a modified Suzuki Hayabusa, which is so powerful that parents would break their children's legs if they saw their children riding it.

What’s more important is that it can be folded and doesn’t take up any space when thrown inside a ring.

Walking downstairs, Lupin in the living room seemed to have been awake for quite a long time. The blanket had been folded neatly, and he was now figuring out how to turn the bed in front of him into a sofa again.

"There's a button on the lower left. Just press it, but..."

boom!

"Oh! Merlin!"

"But be careful, because I forgot to add a damper when I made this sofa. Also, don't be so fast next time, like the Flash. It's better to listen to what others say." As Kaisen said this, he handed over the tissue box and let poor Mr. Lupin wipe the blood from his nose.

"Oh.....where have you been, sir?"

"Just call me Kaisen. I went to buy some daily necessities. If nothing unexpected happens, we may have to survive in the wild for a few days. And this is it." Kaisen said as he handed over the modified Z9 broom.

"Oh my god, Merlin, is this still a Z9?"

“It’s packed.”

"So when do we set off?" Lupin rode on it to test its comfort, but of course he couldn't test its speed.

Even though he couldn't afford it before, he knew the reputation of the Z9 broom. When he experimented in the house, it wasn't the house that lost, but he himself flew out of a big hole.

The house wins, and you become Lupin Pancake or Lupin Sauce.

Chapter 69 Arrival

"The flight is tomorrow afternoon."

Lupin got off the broom awkwardly: "Why do we need to buy a broom when we're going to fly?"

"Because according to typical adventure movies or games, after we get off the plane, we'll most likely have to find a native gentleman to drive us to our destination. There are a lot of troubles along the way, like wild beasts, rebels, or the native gentleman getting greedy for money. Since we've never been to that place before, Apparition and my teleportation are useless, so two brooms will make our journey smoother."

Kaisen spoke such a long speech in one breath, and immediately felt dry in the mouth. He picked up the half glass of water on the cabinet and took a sip. Then he realized that it was difficult for this half glass of water to be kept here for two months and it had not completely evaporated.

It was as if it was waiting here just for Kaisen.

He calmly filled the glass of milk and drank it all in one gulp.

A small amount of menstrual fluid can be easily controlled.

"By the way, you should try this milk too. It's good for your health." Kaisen said as he took out a new cup, filled it with milk and handed it to Lupin.

"Thank you."

Kaisen watched Lupin drink it all in one gulp, but... he couldn't tell anything.

Maybe wait until the full moon night?

"It's almost time now. Come with me, Frommi, let's go have some dinner." Kaisen called Lupin to the garage, one in the driver's seat and the other in the passenger seat...

Even if Lupin didn't want to sit in the passenger seat, there was nothing he could do. This car didn't have a back seat, and he couldn't be put in the front trunk.

"This car looks nice."

"You're a wizard, and you know something about cars?"

“So it looks good.”

"Yeah, I have a good eye for it."
