Hogwarts wizards who signed in to Middle-earth.

Chapter 251 Early Warning
The Black Barbarians quickly assembled and formed a fully armed cavalry force.

The leader of the Black Barbarians, Brog, and the tribe's most powerful warriors, rode winged eagles.

Considering the long journey and the ever-changing situation, Dui took out several boxes that had been expanded by the Unseen Stretching Charm and packed all the Black Barbarian cavalry and Rohan troops inside.

Only a dozen or so Black Barbarian warriors who had gained the approval of the Hippogriffs remained, along with the leader of this expedition—King Rohan's cousin—and together they rode Hippogriffs to Edoras, the capital of Rohan, at top speed to provide assistance.

As for why he didn't choose the faster door key, Dui said that even if he used up all his magic power, he still couldn't teleport that many people.

After all, the number of Black Barbarian warriors and horses dispatched this time exceeded ten thousand.

The portal key teleportation consumes Dui's magic power. Each additional person teleported consumes one more unit of magic power. He can teleport hundreds of people, but he is powerless to teleport tens of thousands.

With the departure of the Black Barbarians and Rohan, only Dui remained in Eisengard.

Gandalf also traveled to Gondor before the Black Wildlands agreed to help them, using the Portkey to organize the people of Gondor against the invasion of Mordor.

"Aslan, you'll have to work hard these next few days, patrolling and monitoring the area. If you spot any enemies, warn me, understand?" Dui gently stroked Aslan's head and instructed him softly.

The griffin Aslan is very intelligent and, apart from not being able to speak human language, is almost no different from an ordinary person.

Hearing Dui's words, it obediently nodded, rubbed against Dui's hand, and immediately flew into the sky, circling continuously above Eisengard, using its keen eyes to monitor the situation below.

Dui returned to Osankta, patted the three-headed wolf, and instructed, "Cerberus, be on your guard these next few days. Enemies may sneak over. Remember not to let them get close to here."

The three-headed wolf, whose two heads were sleeping, stopped sleeping altogether, stood up straight, and howled to ensure the mission was completed.

"Good boy! I'll reward you with a cow later." Dui treated them all equally, patting each of their heads and smiling as he spoke.

The three-headed wolf Cerberus's six eyes gleamed, its tail wagged rapidly, and it stood tall and proud on the first floor, its three heads pointing in three different directions, always on guard against any potential enemies.

Dui arrived at the platform at the top of the tower, gazing eastward with a slight frown and a somewhat solemn expression.

This sudden invasion of Gondor and Rohan by Mordor caught Dui off guard.

Moreover, he felt a vague unease; Sauron's actions this time were probably not simple and could not be merely for the purpose of conquering Gondor and Rohan.

Sauron is a very cunning man, like a venomous snake in the dark, patiently lurking until the opportunity to strike is ripe for the kill.

Just like after his defeat in the final battle of the alliance, he lay in the shadows for thousands of years, accumulating strength to recover, so that Gandalf, Galadriel and others could not find his return until he was exposed in Dorgon, and then he fled back to Mordor to continue to accumulate strength.

Sauron's power has not yet fully recovered, and his influence has not increased significantly, so there is no reason for him to launch an invasion now.

Dui had a premonition that this mobilization of Mordor was somehow related to him.

This premonition became more acute after Dui created the Philosopher's Stone and his soul underwent a transformation.

Just as Gandalf and others never doubted their premonitions and intuitions, Duy also trusted his intuition.

Therefore, he needs to take precautions in advance.

Dui stood on the platform at the top of the tower, wearing the Ring of Power and holding a staff, casting spells with the amplification of the wizard's tower, Osank Tower.

"Super strong armor protects the body, enhances all defenses, and makes it as solid as a rock..."

A series of spells were released from the staff, forming a complex incantation that created a white, net-like dome around the core of Osank Tower and the outer walls of Eisengard, enveloping Osank Tower.

After the Philosopher's Stone was completed, Dui's soul, spirit, and body underwent a transformation, and even his magic power doubled. Now, in terms of magic power alone, Dui has already reached the level of Dumbledore and Voldemort in the wizarding world.

Even so, with the aid of the Ring of Power and the staff, casting a massive protective dome over Eisengard still left Dui exhausted.

But the result was good; the huge dome, though seemingly as thin as a cicada's wing, was sturdy and indestructible.

Ordinary magical attacks cannot break through the dome's defenses, and anyone who tries to force their way close and pass through will be instantly reduced to ashes.

However, Dui still modified the dome based on Grindelwald's method of improving Fiendfire, so that those who were loyal to him or had good intentions could pass through it smoothly.

After doing all this, Dui took out the golden cup and summoned clear water.

With his other hand, he took out the magic stone and stirred it a few times in the clear water of the golden cup.

The clear water in the glass quickly turned a ruby ​​red, looking just like red wine.

Then Dui drank the water in the glass in one gulp.

The next second, a surge of energy, full of vitality and magic, flowed into all parts of his body, quickly replenishing the magic that Dui had just lost and bringing his physical functions to their peak.

This is the combined effect of the Golden Cup and the Philosopher's Stone.

The golden cup can nourish the body, while the magic stone can replenish magic power. Using the two together will ensure that Dui never falls into a state of fatigue or magic depletion.

Duy put away the golden cup, gazing expectantly at the ruby-like Philosopher's Stone in his hand. Had it not been for the unexpected invasion of Gondor and Rohan by Mordor, he would already be in the Potions Chamber at Windrise, crafting his own elixir of immortality.

The Philosopher's Stone itself cannot directly grant immortality, but it is the main ingredient for making elixirs of immortality.

Making a pot of elixir of immortality can extend one's lifespan by thirty years. As long as one has enough of the elixir and takes it without interruption, one can live forever.

More importantly, Dui's Philosopher's Stone is of perfect quality, unlike Nicolas Flamel's Philosopher's Stone, which can only grant immortality but cannot stop the aging process.

His Philosopher's Stone is the true source of immortality. Once he takes the elixir of immortality made from the Philosopher's Stone, his bodily functions will remain at his current age, and he will neither age nor die.

Dui was just waiting for the crisis in Eisengard to be resolved before returning to Windrise to create the elixir of immortality.

After all, he's not young anymore. If he delays any longer, he'll end up as an old man, which would be terrible.

Don't think that only women love beauty; a man like him also hopes to stay young forever.

However, looking at the magic stone in his hand, Dui suddenly paused, and then a guess flashed through his mind.

Could Mordor's sudden attack be aimed at the Philosopher's Stone in his possession?

He remembered that the Philosopher's Stone could not only be used to make elixirs of immortality, but also to restore the physical body.

That's why Voldemort possessed Quirrell when Harry Potter was a first-year student, in an attempt to steal the Philosopher's Stone hidden in Hogwarts.

Sauron's current situation is actually quite similar to Voldemort's.

Voldemort is immortal thanks to Horcruxes, and Sauron is immortal thanks to the One Ring; both exist as spirits.

As early as the Second Age, Sauron corrupted the Númenor people, causing the island of Númenor to be punished by the gods and sink. Sauron was also punished by losing his body and the ability to shapeshift.

But Sauron regained his physical form by using the One Ring.

However, this physical body exists solely because of the One Ring. If the One Ring is separated, such as in the Last Alliance battle when Sauron's finger wearing the ring was severed by Isildur's broken sword, he would suffer a severe injury, his physical body would disappear, and he would lose his power.

That's why Sauron kept trying to find the One Ring in order to regain his physical body and power.

However, the Philosopher's Stone can also restore a person's physical body. Before finding the One Ring, this is definitely another way for Sauron to regain his body and power.

Dui recalled that when Sauron was making the Philosopher's Stone, he had tried to spy on this place, although Galadriel had stopped him in time.

But with Sauron's strength, even a single glance might be enough for him to discern the Philosopher's Stone's power.

After all, he was the one who created the One Ring and the Ring of Power; his vision and wisdom far surpassed that of everyone else.

Thinking this, Dui suddenly felt heavy-hearted.

He originally thought that at most, it would be the resentful Saruman who would take this opportunity to try to reclaim Eisengard.

But if the Ringwraiths are still there, or even if Sauron himself arrives, and he senses something is wrong, then he really will have no choice but to run away and abandon Isengard as his stronghold.

But the thought of the fireplace downstairs brought him a little relief.

If Sauron really comes, he will immediately call for help from Lorien and the Valley through the fireplace.

With powerful elves like Lady Galadriel, Elrond, and Glorfindel the Golden Flower Lord present, there's nothing to fear even if Sauron himself were to come.

If they could banish him back in Dorgu, there's no reason they can't this time.

Then Dui looked at Eisengard and realized that he was the only one there, along with the griffin Aslan and the three-headed wolf Cerberus, and felt that it was still a bit too little.

So he took out the victory horn given to him by the blue-robed wizard Romistanus and blew it loudly.

The sound of the horn was not loud, but it traveled extremely far.

At the summit of Fengyun Peak, Smaug, the dragon lying in the golden mountain, opened his eyes. He heard the summoning voice, immediately rose from the golden mountain, and without hesitation, crawled out through the dragon passage.

The basilisk that had been sleeping in the secret chamber also awoke, crawled out of the chamber through the pipes, and emerged from the black lake at the foot of the mountain.

Amidst the gasps of the nearby residents of Hogsmeade, the dragon Smaug flew out of Hogwarts Castle, swiftly swooping down to snatch the basilisk that had emerged from the lake with both claws.

Surprisingly, the enormous 80-foot-long serpent did not resist. Instead, it coiled itself around the dragon's leg and flew southeast with the dragon.

Accompanying him was the giant eagle, Thorondo, whose speed was even faster than that of the dragon. Upon hearing the summons, he flew towards Eisengard at full speed.

Only the giant octopus Kraken remains responsible for guarding the Black Lake defenses of the castle.
