Hogwarts wizards who signed in to Middle-earth.

Chapter 111 Magic Cycle
As Beorn transformed into a giant bear, the savage and wild feeling of oppression came over him.

Even though he knew the giant bear in front of him was Beorn, he still felt the urge to retreat.

"Beorn, please don't resist for a moment. Let me check the magic circulation in your body, okay?"

The giant bear nodded when he heard this, and signaled him to come as he pleased.

Seeing that Beorn agreed, Dui immediately put his hand on the giant bear's skin and slowly injected magic into it to feel how the magic in the giant bear's body worked.

The reason why Animagus cannot transform into a magical creature is because the magic of wizards and the magic of magical creatures have an essential difference in operation.

Once this magical mode of operation is forcibly broken, it can easily lead to unpredictable serious consequences.

Just like the five-legged monsters in the magical world, it is said that they were transformed by wizards.

However, because the way the magic power in the body works changed during the transformation process, it can never change back after becoming a five-legged monster, thus adding a new creature to the magic world.

In the wizarding world, there are very few wizards who practice Animagus, and even fewer who succeed.

There were only seven registered Animagus in the entire 20th century. Even if you include those who practiced secretly and were not registered, there were not many in total.

There was no successful precedent for transforming magical creatures, and those that did were subject to serious consequences.

Therefore, wizards in the magical world never dare to easily try to transform Animagus into magical animals.

But it's different here in Dui.

Although Beorn is a skin-changer, he can transform into a giant bear, making him a good reference.

If he could unlock the secret of Beorn's transformation and integrate it into his own Animagus, perhaps he would be able to have a stronger Animagus.

Dui carefully felt the operation of magic power in the giant bear's body, and felt the difference between the way magic circulated in the giant bear and his own body.

Beorn also has magic power in his body, and it is not low.

This is also the reason why he can transform into a giant bear.

However, as Dui continued to sense the magic operating system in the giant bear's body, his expression became more and more solemn, and finally he could only sigh and withdrew his hand.

"Thank you, Beorn, you can change back."

The giant bear let out a low growl upon hearing this, and its huge body quickly shrank before eventually turning back into human form.

Beorn put his clothes back on and asked, "Anything?"

Dui nodded. "I've learned a lot. The way your magic circulates is very unique. If I can replicate it completely, perhaps I can unlock the secret of the skin-changer's transformation."

"It's just that your magic circulation system is too complicated. If I want to remember it all, it will probably be a huge project. It will take at least several years, or even longer!"

The circulation of magic power is similar to the circulation of true energy in the meridians in martial arts novels, and will form a complete and complex magic power circulation system in the body.

The circulation and operation of a wizard's magic power are different from those of magical creatures.

If a wizard forcibly transforms into a magical creature, the magic cycle in his body will be broken.

At the very least, the magic power loses balance, becomes disordered, and turns into a dud.

In serious cases, you will be transformed into a magical creature forever, with your soul trapped in the body of a wild beast, which is even worse than the blood-cursed orc!

After all, it is impossible for two magic circulation systems to exist in a person's body at the same time.

But Beorn was different.

Dui discovered that when he was in human form, there was one magic cycle, but when he transformed into a giant bear, there was another magic cycle system.

Beorn can switch between the two systems freely, allowing him to change back and forth between human form and giant bear form.

If he could find the switching point between the two, Dui might be able to find a way to turn an Animagus into a magical creature.

But this is still a bit too far away for Dui at the moment.

It would take a long time to record the complex magic circulation system in Beorn alone.

And there cannot be any deviation or omission in the middle.

Otherwise it would be a serious magical accident.

In response, Beorn waved his hand very readily and said:
"What's the big deal? If you want to do research, you can always come find me. You can even live here permanently. I'm the only one here all year round. You're more than welcome to come and visit!"

Dewi was very grateful to Beorn. He had been prepared to be rejected and even treated hostilely by Beorn.

After all, the ability to transform is the basis of the skin-changers' strength. If it is cracked by outsiders or a method of restraining it is found, it means that the power of life and death of the skin-changers is handed over to others.

But Beorn allowed Dewi to study him, which was a great trust.

Du Yi accepted the favor, so naturally he had to repay it.

He thought about it and decided that since Beorn had magic in him, he would make a wand for him.

Beorn was also very surprised to hear that Dewi was going to make a wand for him.

"Is this okay? I mean, I'm just a skin-changer. Can I really cast spells with a wand?"

Dui nodded affirmatively.

"You have magic power in your body. As long as you have a wand, you can cast spells. If you don't believe me, you can try using my wand."

Dewi handed Beorn his wand and taught him the basics of the Luminescence Charm.

Dewi's wand was naturally not suitable for Beorn, but it was not difficult to cast a simplest fluorescent spell with it.

As a little fluorescence lit up at the tip of the wand, Beorn smiled happily, as if he had seen the most novel thing.

He immediately couldn't wait to ask Dui: "Dui Er, please help me make a magic wand. This is amazing!"

Dui smiled and nodded.

"Of course, this is what I was going to do." To make a wand for Beorn, the first thing is naturally to find a suitable wand shaft and core.

The materials suitable for making the core of the wand in his hand were Galadriel's hair and the feathers of a giant eagle.

However, after Dui took out these two, neither of them was suitable for Beorn.

It was not until Beorn brought out a warg that he had killed the day before that Dewi found the core of his wand - the heart and tendon of the warg.

As for the staff, there are also many magical trees in the dark forest.

Dewi rode his broom into the woods and found a suitable shaft for Beorn, a piece of wood cut from a very old oak tree.

After collecting the materials for making the wand, Dewi began to make a wand for Beorn.

But Dui doesn't plan to make it here.

The wand-making process is complicated and time-consuming. He has been away from River Valley for some time and doesn't know whether the Orc army has arrived?
Especially the giant dragon, I wonder if it has been behaving well during the days I was away?

"Beorn, are you interested in experiencing Floo powder teleportation?" Dui invited him with a smile.

Gandalf was busy dealing with the coming of the Orc army, so he couldn't just sit there and do nothing.

By the way, he invited Beorn to go to Dale and join the team to fight against the Orcs.

He remembered that in his original destiny, this man had also participated in the Battle of Five Armies, inflicted heavy casualties on the Orcs, and even killed Bolg, son of Azog.

When Beorn heard that they were going to fight against the Orcs, he agreed without thinking.

All his people died at the hands of Orcs, and his hatred for Orcs was deep in his bones. He would agree without hesitation to anything that meant killing Orcs.

So after arranging the livestock, the two of them used Floo powder to teleport directly to River Valley City through the fireplace.

In the fireplace of River Valley City, green fire flashed, and Dui walked out first.

The next second, the tall Beorn also appeared. He accidentally inhaled a puff of cigarette ash, and coughed a little embarrassedly as he crawled out of the fireplace with his back hunched.

Seeing this, Dui waved his hand to clean the cigarette ash off his body and asked with a smile.

"Beorn, are you alright?"

Beorn coughed until tears came out, waved his hands, and looked speechless.

"Ahem... I'm fine...!"

Bilbo heard the noise and walked in from outside. When he saw the two of them, his eyes lit up and he ran forward quickly.

"Doire, and Mr. Beorn, why are you here together?"

"Long time no see, Mr. Baggins." Beorn greeted politely. He had a good impression of this halfling.

Dewi also smiled and explained, "Beorn is my guest. He will join us in the fight against the Orcs."

"By the way, where's Gandalf? Hasn't he come back yet?"

Bilbo shook his head.

"Bard and the residents of Lake-town have all moved here, but Gandalf hasn't returned yet. I heard from Bard that he went to Mirwood, trying to convince the elves, humans, and dwarves to form an alliance."

Dui shook his head when he heard this.

I'm afraid Gandalf's journey will not go smoothly.

Thranduil is not an elf like Elrond who cares about the world. He only wants to be responsible for the elves of the Woodland Kingdom.

Not to mention forming an alliance with the dwarves, don't even think about it.

Putting this matter aside, he asked, "What are Bud and the others doing now?"

"Bard and his men are now building defenses, preparing to fill the gaps in the city wall to resist the attacks of the Orcs," said Bilbo.

"Then let's go and take a look together!" Dui said.

Then, the three of them went to where Bard was.

Along the way, Dui frowned as he watched the residents of Changhu Town building leak detection tents based on the ruins of the city.

It is now the transition period between autumn and winter, and the temperature in the valley city deep in the north is beginning to turn cold.

Such poor living conditions can freeze people to death.

The three of them walked all the way to the city gate.

At this time, Bud and the men were moving the stones and piling them up one by one at the gap in the city wall.

After moving a large stone, Bud took a breath and saw Dui and the other two. He immediately showed an expression of surprise and joy.

"Duir, Bilbo told me you were away on a long journey. I didn't expect you to be back so soon!"

"Are you repairing the city wall?" Dui said.

Bud nodded.

"Although the walls of Dale are badly damaged, they are still serviceable. I want to repair them as soon as possible before the Orc army arrives. This will also prevent the Orcs from entering the city and harming the residents."

"In that case, I'll help you too." Dui said, pulling out his wand.

Then he waved his wand at the damaged city wall.

"Recover as before~"

The next second, time seemed to flow backwards. Aside from the areas burned by the dragon's flames, the city walls were constantly repairing themselves. Scattered rubble was turning back, filling in the gaps that had been damaged...
