Traveling through World of Warcraft

After Kel'Thuzad was resurrected by Arthas, he became a powerful lich. He explained the Lich King's next plan to Arthas, then opened the portal and summoned Archimonde, one of the leaders of the Burning Legion.

Arthas led the undead Scourge to launch a surprise attack on Dalaran in accordance with the Lich King's plan. Antonidas, the leader of Dalaran, believed that Arthas would attack the Kingdom of Lordaeron first, so he concentrated his main defense forces near Lordaeron. However, Arthas succeeded in conquering Dalaran through a surprise attack.

During the battle, Arthas showed his great strength. With Frostmourne in hand, he rushed into the streets of Dalaran and started a duel with Antonidas. Although Antonidas was a powerful mage, he was ultimately unable to withstand Arthas' attack and was killed by Frostmourne.

This raid brought a devastating blow to Dalaran. The mages in the city fled in all directions, and the city fell into chaos. Arthas took the Book of Medivh after killing Antonidas.

The mages of Dalaran rose up to resist. They used powerful magic to try to prevent the invasion of the undead. However, Arthas and his undead army were too powerful, and Dalaran's defenses gradually became exhausted.

During the battle, Arthas showed his ruthless side. He wielded Frostmourne and killed one mage after another under his sword. His death knights were not to be outdone. They rode skeletal horses and rushed into the mage's formation, killing them wantonly.

Kel'Thuzad commanded the undead army from behind, constantly releasing various dark magics, which put tremendous pressure on the mages of Dalaran.

After obtaining the Book of Medivh, Arthas and Kel'Thuzad released the powerful energy in the book and opened the demonic door to the Twisting Nether.

In the city of Dalaran, Kel'Thuzad stood on a huge platform, surrounded by a group of undead Scourge. Kel'Thuzad was mumbling words, the staff in his hand flashed with evil light, and he was trying to open the portal.

Arthas rode on his undead steed, wielding Frostmourne, and commanded the undead Scourge to guard Kel'Thuzad. His eyes were cold and determined. He knew the importance of this portal and must protect Kel'Thuzad at all costs.

In the distance, Chen Yu commanded the troops of the Dalaran Mage Guild and launched wave after wave of attacks against the undead army. The mages cast various magics, fireballs, ice cones, and lightning intertwined in the air, colliding with the death breath of the undead natural disaster.

On the battlefield, the paladin and the undead looked at each other, and the air around them seemed to freeze. The undead exuded an aura of decay, and their eyes flashed with a malicious red light, while the paladin clenched the hilt of his sword, exuding a divine light.

The Paladin attacked first. He waved the long sword in his hand and rushed towards the undead. His long sword shines with divine light, and every attack can cause huge damage to the undead.

Not to be outdone, the undead attacked the Paladin with their decaying claws and teeth. However, the holy light on the Paladin's body renders their attacks powerless, and their claws and teeth are unable to penetrate the Paladin's armor.

The Paladin continued to attack the undead, and his sword skills were like strong winds and rain, which the undead could not resist. The undead began to retreat. They felt the power of the Paladin and began to be afraid.

However, the Paladins didn't give them a chance. He continued to attack the undead, slashing at them with sword after sword. The undead let out a shrill scream, and their bodies were reduced to ashes under the sword of the paladin.

The soldiers of the Undead Scourge did not flinch. With amazing perseverance and fearless courage, they launched a desperate struggle with the troops of the Dalaran Mage Guild. The skeleton warriors brandished old weapons, made shrill screams, and charged towards the enemy. The giant frost dragon swooped down from the sky, spitting out icy dragon breath from its mouth, freezing the mages in place.

The battle was extremely fierce, with both sides fighting hard for their goals. Chen Yu and his mages want to prevent Kel'Thuzad from opening the portal, while Arthas and the Undead Scourge want to protect Kel'Thuzad and let him complete his mission.

During the battle, some soldiers of the Undead Scourge were hit by the magic of the mages and fell to the ground. But they were soon replaced by other soldiers who continued to fight the enemy. Kel'Thuzad's chant grew louder and louder, and the portal's light grew brighter.

The dark energy pouring out of the portal is endless, and a rich evil aura permeates the battlefield. As Kel'Thuzad chanted, the portal began to shine with a strange light, and demons stepped out of the door one after another.

The first thing that appeared was a group of small demons, they were ghost-like and agile. Armed with short swords and short bows, they quickly integrated into the ranks of the Undead Scourge and fought to defend Kel'Thuzad.

Immediately afterwards, some medium-sized demons walked out of the portal. These demons are tall and muscular, armed with heavy weapons such as battle axes and maces, and join the battle with astonishing strength and power.

Later, some large demons also emerged from the portal. They have wings and sharp claws and can fly freely in the air. These demons brought heavy air support and swooped down upon the Dalaran Mages' Guild forces, attacking with fire and claws.

As time passes, more and more demons emerge from the portal. They come in many varieties, including Demon Hunters, Pit Lords, Succubi, and more. These demons have their own characteristics, some are good at melee combat, and some are proficient in magic. They work closely with the soldiers of the Undead Scourge to form an indestructible line of defense.

Kel'Thuzad looked at the new demons with satisfaction, knowing that his plan was going smoothly. With the support of these demons, he believed that he could withstand the attacks of Chen Yu and the Dalaran Mage Guild and protect the safety of the portal.

With the encouragement of the demons, the morale of the soldiers of the Undead Scourge greatly increased, and they fought the enemy more bravely. On the battlefield, fire splashed everywhere, magic and arrows intertwined, blood mixed with ice and snow. This battle has entered a fierce stage, with both sides fighting desperately for their goals.

After a long and fierce battle, Kel'Thuzad successfully opened the portal. A huge amount of dark energy surged out from the portal, shrouding everything around it. Chen Yu and his mages were forced back by this dark energy, and they could no longer stop the plan of the Undead Scourge.

Arthas looked at the dark energy in the portal, with a satisfied smile on his face. He knew that their goal was about to be achieved and that he would lead the Scourge to conquer the entire world.

Along with waves of evil magic, a huge portal opened in the sky above Dalaran, and countless demons from the Burning Legion poured out of it. Archimonde was their commander.

Archimonde is an extremely powerful demon who is proficient in all kinds of dark magic and possesses powerful strength and evil will. As soon as he appeared, he began to release powerful magic, beating the defenders of Dalaran into retreat.

Archimonde just appeared, and his voice echoed in the hall like thunder: "The Lich King is no longer useful to us. From now on, the Dread Lord will take his place and lead the undead."

The Dreadlord said, "Yes," and disappeared.
