Hogwarts wizards who signed in to Middle-earth...

The troll's cave was nearby, and with the True Knowledge Crystal locking them in place, Dui led them directly to the cave without them even needing to search for them.

The troll cave was as foul-smelling as ever. Upon entering the cave, the group discovered a pile of gold coins and treasures at the deepest part.

With his target clear, Dui ignored the treasure and searched the surroundings for the whereabouts of the elven swords.

Sure enough, Dui soon found several dusty swords in a corner covered in cobwebs and dust.

There were three swords, two long and one short. The two long swords were sheathed in beautiful scabbards with large gemstones on their hilts, while the short sword was placed in a leather scabbard.

These swords have been here for a long time, covered with a thick layer of dust, but there is not a trace of rust. Even the leather sheaths, which are the most difficult to preserve, are as good as new, without any signs of corrosion from the years.

"Is this the magic of the elves?" Dui couldn't help but exclaim in amazement.

"Duir, have you found something good again?" Gandalf noticed Duir's movements and walked over curiously to ask.

Others were also drawn over.

Dui smiled and nodded, displaying the three swords in front of him to everyone: "I have found three swords that look quite extraordinary."

Hearing Dui's words, Gandalf became even more curious. "May I see it?"

Dui handed over a longsword.

Gandalf took the longsword, examined the blade, and commented, "The scabbard is made of ivory, and the carving is exquisite; it looks like the work of elves."

As he spoke, he drew his sword, its blade gleaming with a cold light that was striking even in the dim cave.

Gandalf stroked the blade, looking at the mysterious inscriptions on it, and carefully deciphered them: "Gramdrin, this is Sindarin, meaning hammer that strikes the enemy. It seems this is a sword belonging to the elves."

Gandalf reluctantly put it down, seemingly quite fond of the sword.

He then picked up another longsword, which, when drawn, was a slender, curved blade with an incredibly sharp edge. Engraved on it were inscriptions in the same Sindarin language: "Ocrest, meaning Goblin Cutter; the hilt carries the aura of a dragon. Is it made from a dragon's tooth?"

Gandalf was very surprised. Dragons were Maiar-level creatures, almost invincible. This Elven sword had a hilt made from a dragon's tooth, which meant that a dragon had died at the hands of elves in order to obtain the dragon's tooth.

The others also looked at the sword with curiosity, after all, they were facing a giant dragon on this trip.

Finally, Gandalf picked up the short sword to examine it, but since there were no inscriptions on it, he could not learn anything about it, only that it was also a sword forged by elves.

Seeing Gandalf's gaze linger on the first longsword, Duy smiled inwardly; it seemed this sword and Gandalf were destined for each other.

To Gandalf's astonishment, he handed him the sword that originally belonged to him: "Gandalf, since you don't have a suitable sword, this hammer is yours."

Gandalf truly admired the sword and, without any hesitation, accepted it solemnly, saying, "I owe you a favor!"

Duy shook his head. After several battles with the ogres, his relationship with Gandalf had deepened. He gave the sword not out of any intention to seek repayment, but simply to return it to its rightful owner.

He then turned his gaze to Bilbo, handed him the short sword, and said with a smile, "This sword suits you best; it's yours from now on!"

Amidst the envious gazes of the dwarves, Bilbo, somewhat flattered, waved his hand and said, "Duir, you've already given me a dagger, so I don't need this sword!"

Dui ignored his refusal and shoved the short sword into his hand. "Take it. The previous dagger was just an ordinary weapon and couldn't protect you. This short sword is a weapon forged by elves. Take it to defend yourself."

Seeing Duy's insistence, Bilbo no longer refused and accepted the short sword with a grateful expression: "Thank you, Duy!" He then solemnly hung the short sword and the previous dagger on his left and right sides of his waist.

Then, under the expectant gazes of the dwarves, Dui put away the last of the Beastbite Sword, no longer intending to continue being the money-giving boy.

Gandalf and Bilbo are Duy's acknowledged friends, and Duy doesn't mind giving them the Elven Sword.

However, his relationship with the dwarves has always been that of traders. Although he already possesses the Flaming Sword, he is not generous enough to give it away to them.

Although the Beastbite Sword originally ended up in Thorin's hands, first come, first served. The sword was the first one he encountered, so it was his.

Thorin looked at the Beastbite Sword in Dui's hand and vaguely felt that it was connected to him. The Dragon Fang hilt also carried auspicious meaning, which was vaguely in line with the dragon he would face on this journey to Lonely Mountain.

But he also knew that his relationship with Duy wasn't close enough for Duy to give him a precious sword, so he said, "Duy, would you be willing to trade this Beast-Biting Sword with me?"

"Oh, how do you plan to make the deal?" Dui turned to ask him.

He already has the Blazing Sword, so he doesn't need another one. If Thorin's offer satisfies him, he wouldn't mind letting the sword return to him.

Thorin paused for a moment, then said, "How about I trade one percent of the Lonely Mountain treasure for this sword?"

Dui shook his head: "I don't need the treasure." According to the contract he signed earlier, he owns one-tenth of the treasure in Lonely Mountain. In addition to the treasure in Ancient Tomb Hill and the treasure in the Ogre Cave, he doesn't care about that one percent share at all.

"Then what do you want?" Thorin asked, frowning, assuming that Dui was complaining that the amount given was too little.

Dui thought for a moment before saying, "After you reclaim Lonely Mountain, I hope you will build me a castle atop Windfall Peak, centered around the Tower of Amonsur. I will provide the blueprints, and you will be responsible for its construction."

Since the Tower of Amonthur has already been renamed Hogwarts, he wants the name to truly reflect its meaning.

The dwarves have exceptional skills and brilliant achievements in construction. Many magnificent buildings in Middle-earth were built by dwarves. If Duy wants to bring Hogwarts Castle to life in this world, dwarves would be a good choice.

Upon hearing Dui's request, Thorin frowned even more. This request was no small matter; it could even be described as an exorbitant demand.

After all, the scale of building a castle centered around the Tower of Amonsur is unimaginable, and the manpower and resources required are enormous.

But Thorin hesitated for a long time before finally gritting his teeth and agreeing.

Although building the castle required a lot of manpower and resources, these were no longer problems once he reclaimed Lonely Mountain and became the king of the mountain.

Thus, as fate would have it, the Beastbite Sword returned to Thorin's Oak Shield once more.

The three elven swords in the ogre's cave were divided among Gandalf, Thorin, and Bilbo, while the remaining treasure was shared equally among the sixteen people.
