Now that Ollivand has learned about what Ronan has sent, he is sure that this plan is feasible.

"I think it's barely OK to use magic metal to act as a wand wood, but its properties may be far from the traditional wand. Are you really that determined?"

Ronan nodded, what if he hadn't decided to come here?

"Then it is still the same very important thing as the last one. The core of the rod will be the key factor that determines the performance of this alien magic wand. It is extremely important, but there is another huge difficulty in front of us. Master Ronan, since you said you have read the corresponding books, then I will test you. What is this difficulty?"

Luo Nan Shao recalled it and thought of the answer, and replied: "First of all, it is the appearance. The traditional wand not only saves materials while ensuring performance, but more importantly, its shape is sufficiently balanced, and its minimum cross-section is always a perfect circle. Therefore, as long as you hold its bottom, no matter how you wave it, there will be no anisotropy.

But the great sword-shaped wand I want to make is different. It can only satisfy the face-to-face symmetry and has only one side. In other words, if you want to make it stable, you must ensure that the grip posture is the same every time you cast it.

But fortunately, the one I used as a magic wand was a great sword, which originally had a special holding posture, so I don't think the impact was much.

Then the most important key content is the core of the stick you just mentioned. It must be explained that my big sword is 1.5 meters long, and the basic requirement for the wand for the stick core is that it must continuously form a path from the wizard's hand to the top of the wand.

My big sword is 1.5 meters long for common pole cores. If you want to use it, you must doubling. However, any poubling will have a negative impact on the performance of the pole core. From blocking magic power to instability caused by possible breakage, it will cause a headache for the wizard."

Olivand looked at Ronan in surprise and said with emotion: "Oh my God, it seems that you have done a lot of homework, and you didn't lie to me."

Ronan waved his hand modestly, "It's still not as good as your decades of practice."

"That's of course, otherwise what else do we have to do? Isn't it more suitable for you to make your own wand?"

Ollivander did not struggle with this topic for too long and returned to the previous big issue. He said: "The length of 1.5 meters is definitely a challenge for the current wand making, because no one has ever dealt with such a long wand core.

If you have really studied this problem, you will understand that although in principle, there is basically no difference between creating a gadget and a big thing, if it is placed on the project, there will be big loopholes, which is completely different."

Luo Nan nodded sincerely, that's right!

As a former science and engineering man, Ronan understands the boundaries of science and technology, just like in the world, it is enough to have science, so why do you still have engineering?

Of course, it is because science and engineering solve two problems. The former focuses on the frontier of theory, expands territory in unknown fields, and is full of strength, while the latter is based on the theoretical framework discovered by the former, looking for the possibility of turning the theory into reality.

Such work is boring and tedious, and it is easy for the romantics to lose their enthusiasm, but this is the real problem faced by reality.

There are many experiments that can be carried out smoothly and smoothly in the laboratory, but once it is enlarged, problems will arise. The scale of industrialization that can be applied in practice will be tens of thousands or thousands of times that of pediatrics conducted in the laboratory.

What science needs is to do this experiment and then reproduce it. This process generally ranges from dozens to thousands of times. What engineering needs to do is to enlarge it, amplify it and then amplify it to solve all the problems along the way, so that it can provide products to human society steadily. This process is eternal repetition, but the problems encountered in each repetition will be different, which can be called torture in torture.

"The second question," Ollivander pointed out again, "we don't have such long materials to make such long stick cores.

You should know that neither unicorns nor phoenixes are big. They may have appeared larger individuals in the past, but in any case, their tail hair or tail feathers cannot be as long as one meter five."

Ronan nodded and asked, "So what do you think of the dragon's nerves? The dragon is big enough, and its nerves must be long enough, which definitely meet my requirements."

Olivande shook his head: "So the knowledge in the textbook is always the knowledge in the textbook. This is what you take for granted. The dragon's nerve is indeed a very excellent core of the rod, but not all the nerves of the dragon are.

If you want to make a qualified core, the prerequisite is that its texture must be single, and it must also meet the requirements that it can be made into the precursor of the core without deterioration.

Then, the dragon's big nerve is eliminated. Although the magic is effective, it is also its disadvantage. Its texture is extremely unstable. If you use this thing as the core of the stick, I think your magic wand will have to be replaced once a month.

So are other nerves of dragons OK? No, the dragon nerve I admire most is the dragon's heart nerve, but you will know that it is not that big at all, 1.5 meters? It is far from enough, it can burn high incense if it can reach 50 centimeters."

Ronan understood that he was really thinking too much, but fortunately, he didn't really like the dragon in this world. Now the sword of Anubis has long been separated from the mortal fetus in the Elda world. If the core area of ​​this world is replaced with the dragon nerve in this world as the core, Ronan feels that this dragon is not qualified.

Fortunately, Ronan has another treasure.

"Master Ollivander, what if I say I have such a big dragon? So what should I say about this?"

Ollivander looked suspicious: "Really?"

It is an exaggeration to have this big sword. As for a larger dragon? You should know that if a three-dimensional creature wants to make a certain size of its original three times, its size must be twenty-seven times. Even the largest Ukrainian iron belly does not have this size, which is too scary.

However, Ronan in front of him is not an ordinary person. It can be explained by the fact that he can take out this big sword. This sword alone is enough to afford his full wealth.

"I really have it, but it's not here, I exist somewhere else."

"Save? Is it dead?" Ollivander's head shaking like a rattle when he heard it. "If you die for too long, the dragon's nerve material will also become worse. If you die for too long, you will be completely finished."

“So I used ice to save it.”

"Frozen? That's even worse, ice crystals will destroy the dragon's nerves."

"But what if I didn't give ice crystals a chance to condense? You may not know that I am an alchemist, the very excellent kind."

"Oh, Merlin is here. Today, when the inheritance of European alchemy is almost cut off, has an alchemy master from Asia actually appeared?" It's not that Ollivand couldn't believe it, it was mainly because it was too unreal.

Alchemy originated in Egypt, developed in Greece, and prevailed in Rome. It then spread throughout Europe with the demise of the Roman Empire. What is the matter of Asian wool?

"You just underestimate me too much, look..." In order to make Ollivand believe this, Ronan did not use traceless alchemy. He honestly drew the refining formation on the ground as he learned alchemy for the first time, and then placed his hands on it.

"Still, start."

So shiny, the blue light flashed, and the whole store became new.

Ollivander's eyes lit up: "That's it! Merlin, the descendant of alchemy is actually an Asian, my god, but even if you are an Asian, I think Nick Meller will be very pleased.

It's very difficult. What a beautiful art for alchemists. The master of runes. Unfortunately, they were gradually abandoned because they were not good at fighting. The cruel and perverted world!

If you are an alchemist, then I think we will be able to work together very happily.

Then we can start our work immediately. First of all, the production of the core of the staff. Let us find the dragon corpse you saved. Let me see how big the dragon you mentioned is?"

Ronan nodded, moved as soon as he spoke, so he patted his right hand on Ollivander's shoulder.

Ollivander: "Hey...ah?"

The Ollivand Magic Store suddenly turned into a leaky balloon and a hole appeared. Then Ronan and Ollivand disappeared into the hole, and then the store returned to its former appearance.

The Antarctic Underground of the Small World Planet...

"Where is this place? It's really cold..." Ollivand quickly waved his wand to warm his body. "Quickly warm, keep the barrier... Well, it's much better."

Then he had the time to see the surrounding environment. It seemed like an indoor space, but it seemed not, because the light here was not very natural, but it was too wide, and it really looked like a polar ice field.

But does Britain have a door key to the North Pole? No, it doesn't even look like the North Pole, because the temperature in the North Pole is not that low, maybe it's the South Pole?

"Did you put the door key in Antarctica? It's such a luxury..."

Ronan: "This is indeed Antarctic, but it is not the Antarctic you think. Forget it, it's too troublesome to explain. Just think that I used the door key and come here."

"Well, this place is so bright. By the way, the time is just the extreme day in Antarctica, right? Why didn't I see the sun?"

The two walked forward for a distance, passed through an extremely cold fog, and then came to the front of a giant.

"Where is the dragon corpse you mentioned? This key is too far... Oh, my Luo Tianyi! (God)" Ollivander just complained, and saw a huge scale with dragon-like characteristics. Then, looking around, a hill appeared in front of him, causing him to sit on the ground.

"Are you sure this thing is called a dragon?"
