Sitting on the couch at Hagrid's house, Rochew held a notebook and carefully laid out plans with an owl quill.

A high temperature and constant fire source can be provided by fire magic, and if Luo Xiu learns high-level fire magic, then he himself is a stable fire source.

The same goes for electric support, except that what he needs to learn is replaced by lightning magic.

Experimental equipment is not a big problem, he can use Hagrid's carpenter tools to modify, in addition to the most basic transfiguration in magic, this need can also be satisfied.

In the end, the biggest problem was the acquisition of rare metal materials, and it was impossible for Luo Xiu to ask Hagrid to help him find some palladium or uranium...... These words should never appear in Hagrid's vocabulary.

"That's a tricky question."

Luo Xiu drew a large circle in his notebook with an owl quill, which indicated that the question was unanswered, but Luo Xiu was convinced that he could find the answer in the magical world of magic.

At noon, Hagrid returned with Huang Cen Mu, and the amount he brought back far exceeded Luo Xiu's needs.

"Come and see, Xiu, come and see these skullwoods, they are all the best products I found in the Forbidden Forest, and they are perfect for making wands." Hagrid shouted excitedly.

Luo Xiu went over to check it, and these shuangcen woods were really of high quality.

"Thank you so much, Hagrid, I think I can make a very powerful wand." Luo Xiu said with a smile.

"Oh, really? Then I'll wait and see. Hagrid smiled and said that he didn't have much hope for Luo Xiu, after all, Luo Xiu had only taught himself for one night, and making wands was a craft that needed to be honed over the years.

After lunch, Luo Xiu began to work on the making of wands, a craft that is indeed a technical task that cannot be mastered by beginners.

But Luo Xiu had made a manipulator, prepared a graphene battery, and finally built the Ark Reactor, and compared to these projects, it was not difficult to build a magic wand.

At the beginning, it was the polishing of the unicorn horn, Luo Xiu carefully trimmed, smoothed, and polished layer by layer, grinding a unicorn horn as thick as a tree branch to the thickness of chopsticks.

By the time the work was done, the sun had set over the western slopes.

At night, the light was dim, and it was not easy for Luo Xiu to continue working, so he lay on the table to draw drawings of his wand, and used an owl quill to draw on parchment.

Hagrid watched with great interest, giving advice to Luo Xiu from time to time, and he held a glass of mead in his hand, and several times the mead dripped down his thick beard onto Luo Xiu's drawings.

Finally, the wand was designed to be fifteen inches long, with the unicorn horn as a single core and the skullwood wrapped in the outer wing, which obviously carried a lot of weight when crafted, given the weight of the unicorn horn itself.

Luo Xiu and Hagrid carefully studied the design drawings and nodded with satisfaction.

"It's going to be a masterpiece." Hagrid said with a smile.

Luo Xiu also agreed: "Yes, it is almost like a work of art. ”

——————

As soon as it was dawn the next day, Luo Xiu began to cut the shuangcen wood.

The bark of the wood is first peeled off and dried, and then it is carved into the desired shape according to the drawings.

Finally, dig out the space in the middle to store the core of the rod, place the unicorn horn in it, seal the sides and brush it with a thick layer of wood wax oil.

After a series of processes, another day passed, and when the wood wax oil on the skullcap wood was absorbed by the wood and the wood glue was dried, the magic wand was completed.

"Well, it looks like this wand is doing a good job." Hagrid looked at Rohew's work with a smile and nodded, "To be honest, none of my wands are so exquisite, and I think Ollivanders in Diagon Alley would have shouted in surprise if he had seen your masterpiece." ”

"Thank you, Hagrid, it's a great compliment to me." Luo Xiu nodded in thanks.

Hagrid rubbed his hands excitedly: "I can't wait to see the day when you use it, but Luo Xiu, you must know that the wand will choose its own master, even if this wand is made by you, it may not obey you." ”

"Then let's wait and see." Luo Xiu smiled and said, "I believe I can tame it." ”

After dealing with the wand, Rosho left Hagrid's hut under the pretext of going out for a walk.

In fact, he didn't go for a walk, but approached Hogwarts Castle by taking a path.

The afternoon sun was very comfortable, and the students wandered leisurely on the grass between classes.

Dressed in red and gold uniforms are Gryffindor students, whose emblem is a proud and heroic lion; The emblem of the hospital is a soaring eagle in Ravenclaw, and their uniforms are mainly blue; The Hufflepuff uniform is yellow and black, and the emblem depicts a cute badger; As for the Slytherins, their uniforms are green and silver, and their crest features an entrenched snake.

Rosho crept closer to the Hogwarts students, trying to keep himself as unobtrusive as possible—but he was the only one on the lawn who was dressed in tatters, which made it hard not to be a prominent target.

For this reason, Luo Xiu didn't dare to get too close to them, he pinpointed Malfoy in the crowd in a green and silver uniform, and then whispered his name.

"Malfoy! Malfoy! ”

After a few calls, Malfoy noticed him.

"Oh my God, Luo Xiu!"

Malfoy was very surprised, and slipped over with Goyle and Crabbe.

"My God, Luo Xiu, it's really you! Where have you been these days? I thought you had left Hogwarts! Malfoy whispered, looking around warily as he spoke—he didn't want to be caught mingling with people outside the school.

Goyle and Crabbe were not as careful as Malfoy, and they were both very happy to see Rosho.

"Xiu, where are you hiding? I've been worrying about you these days. ”

"Yes, I talked to Goyle about you yesterday, and I'm worried that you'll get lost in the Forbidden Forest and be eaten by werewolves or other monsters!"

Luo Xiu smiled lightly: "Don't worry, I'm not so easy to get into trouble." ”

Goyle nodded: "That's right, your ability is stronger than several of us, and it's not our turn to worry about you......"

Malfoy cautiously asked, "Xiu, what are you looking for us for?" I'm glad you're okay, but you need to be careful, you're not a Hogwarts student right now, and I don't want to cause unnecessary trouble......"

Luo Xiu knew that Malfoy's worries were not unreasonable, and immediately said straight to the point: "It's very simple, I'm here to borrow something from you." ”

"Borrow something?" Crabbe hurriedly asked.

Luo Xiu lowered his voice: "Books, magic textbooks, I need some textbooks about fire magic and thunder magic, the more the better......"
