Summon the Villain: Marvel.

Witchcraft, Billy Kaplan's eyes became cold and firm, and his fingers quickly drew a complex rune in the air. As his spell sounded, a fragment of the Dark Book appeared in his hand, emitting a strong evil breath.

The environment of the castle suddenly changed, and the four were instantly teleported to a place full of gloomy atmosphere, surrounded by broken tombstones, as if it was a forgotten cemetery. This environment was created by the sorcerer Billy Kaplan using real magic, and combined with the necromancy magic on the fragments of the Dark Book, it formed an extremely terrifying scene.

In this dead silent cemetery, a large number of dark shadows suddenly emerged, gradually condensing into shape and transforming into horrifying undead creatures with distorted faces and eyes full of murderous intent.

"It's the Dark Book!" Wang was shocked. Looking at the unfamiliar environment around him, a familiar feeling came over him. He hesitated in his heart: "There is actually a shadow of chaos magic in it. Who is the other party?"

But danger was approaching, and Wang shouted, "Everyone be careful, the other party is using the necromancy magic of the Dark Book." At the same time, he immediately launched the spell of Vishanti magic, trying to use his own magic power to fight against these undead creatures. The halo in his hand emitted a bright light, releasing powerful magical energy, freezing one of the undead creatures in place.

Nathan Hawke's face was calm, electric energy flashed around him, and he tentatively used his ability to repel a deadly creature. He concentrated his mind and used telekinesis to turn the objects around him into deadly weapons, throwing them at the deadly creature.

Kang Ze quickly activated his nano armor, and the surface of the armor flashed with blue energy light, and his vision became clearer. He calmly analyzed the situation, trying to find the weaknesses of the undead creatures and use the weapons of the nano armor to accurately strike.

The sorcerer Billy Kaplan stood aside, watching all this with a cold look. He lightly drew his fingers through the air, and the undead creatures followed his command and began to attack Wang, Nathan and Kang in an organized manner.

The king's Vishanti magic continued to be released. Frost and cold filled the air, constantly freezing the undead creatures, but they seemed to have immortal power and could always recondense in the cold.

Nathan's electrical energy flashed, and he used telekinesis to control the objects around him to attack. Arcs of electricity flew and hit the undead creatures, but these creatures also had abnormal endurance and were not knocked down by the electric shock.

Kang is highly mobile under the protection of the nano armor. He uses the armor's weapons to strike quickly, trying to find the weaknesses of the undead creatures. However, the undead creatures are numerous and their attack methods are unpredictable, which makes Kang feel stressed.

The undead creatures released by the fragments of the dark book of sorcery Billy Kaplan made the scene extremely chaotic and dangerous. Wang, Nathan Hawke and Kang tried their best to fight against these harsh environments. Nathan Hawke kicked a undead creature away and quickly came to Wang's side.

\"Why are you using ice magic? Will it be useful against necromancy?" Nathan Hawke asked.

The king paused for a moment, then replied, "I tried to use ice magic to freeze the energy of the necromancy magic to see if I could stop the opponent's actions, but the effect was not very good. However, I have another method that can use the purification magic in Vishandi magic, but it takes some time to perform."

Nathan Hawke showed a resolute smile and said, "Don't worry, let your spell work, I will protect you."

Nathan Hawke began to mobilize his electrical energy. The arcs around his body flickered more and more, forming an electric barrier that blocked the surrounding undead creatures. His body quickly shuttled between the undead creatures like an electric current, punching and kicking them away.

At the same time, the king began to gather the power of Vishanti's magic. He closed his eyes, made his hands into claws, and began to silently chant a spell. Around him, light began to gather, forming a bright aura that began to spread.

Kang, under the protection of the nano armor, was also trying to share the pressure. He used the armor's weapons to launch quick strikes, trying to buy more time for Wang to cast spells.

Undead creatures continued to emerge, trying to approach Wang and Nathan Hawke, but Nathan Hawke's electrical barrier always kept them out, and Wang's aura became more and more powerful.

The light gathered by the King's Vishanti magic became more and more dazzling, and the surrounding aura became more and more condensed. This purifying power began to spread, gradually repelling the dark energy around the undead creatures, causing them to be restrained to a certain extent.

However, Billy Kaplan realized that things were not going well, and he knew that if the king's purification magic was successful, then his plan might be seriously threatened. He began to chant the special spell in the Dark Book without hesitation, and a strong evil breath spread.

His fingers drew a series of complex runes in the air, and a purple-black magical energy began to gather, forming a twisted vortex. This magical vortex was full of dark power, like a huge black hole, swallowing up the light and breath around it.

\"The dark void is getting worse and worse, seizing the power of purification and destroying everything!\" Billy Kaplan chanted the spell coldly, his voice full of strange power.

As he chanted, the dark magic vortex twisted and began to spread rapidly towards the king. The king felt an ominous force approaching, and he quickly increased the speed of the purification magic.

At this time, Nathan Hawke quickly came to the king's side, and the electric barrier was still firmly blocking the undead creatures outside. He stood in front of the king, with a firm determination flashing in his eyes.

The dark magic vortex finally approached Wang and Nathan, and Billy Kaplan's eyes flashed with a hint of pride. However, when the dark magic vortex was about to touch Wang and Nathan, Nathan suddenly took a step forward, and his fist flashing with electricity directly hit the dark vortex.

Darkness and electricity intertwined, making a piercing howl. The dark magic vortex was hit by the electric arc and began to twist and disintegrate, eventually collapsing completely under the impact of the electricity.

Billy Kaplan's expression instantly turned ferocious. He didn't expect Nathan Hawke to appear at the critical moment and break his dark magic offensive. He immediately realized that his plan had been exposed and he had to take action as soon as possible.

At this moment, the undead creature let out a ferocious howl and pounced on Wang and Nathan again. However, Wang's Vishanti magic had achieved some effect, and the undead creature was restrained to a certain extent, and its movements became slow.

Nathan Hawke and Wang worked together again to fight against the attacks of the undead creatures with a higher level of tacit understanding. Nathan's electric energy flashed in the air, and he used telekinesis to control the surrounding objects to attack, buying more time for Wang to cast spells.

Under the protection of the nano armor, Kang also threw himself into the battle. The weapons of his nano armor emitted sharp light and accurately hit the weaknesses of the undead creatures.

As the king's purification magic continued to gather, the surrounding aura became brighter and filled with pure power. The king's hands continued to form claws, and a grand halo appeared above his head. The pattern in the halo became brighter, like the gate of heaven.

The energy of purification finally reached its peak, and Wang shouted, "Purification!"

As he shouted, the pattern in the halo burst into dazzling light, like a huge pillar of light rising into the sky. The pillar of light emitted a faint halo like a waterfall, like a solemn holy light, covering the entire cemetery.

The undead creatures felt the arrival of the purifying power and let out shrill howls. Their bodies began to gradually dissipate, the dark energy was dispelled, and they turned into nothingness amidst the screams.

The king's purification magic was successful, and the gloomy atmosphere of the cemetery gradually dissipated, replaced by tranquility and light.

\"Handsome, King.\" Nathan Hawke said happily.

Kang also breathed a sigh of relief. The blue energy on the nano armor gradually weakened. He smiled and said: "We successfully repelled them."

However, at this moment, Billy Kaplan's face became even gloomier. His plan was seriously disrupted, which was something he had not expected.

"Damn it! Damn it! No one can stop me from seeing my mother..."

Billy Kaplan's face turned grim.

"determination!"

Billy Kaplan began to chant the spell again, this time, his voice was even deeper, full of darkness and death. His fingers drew a strange rune in the air, and the air around him began to twist, forming a dark vortex.

\"Dark Void, merge with my power and manifest as demonic force!\" Billy Kaplan roared, his voice full of fanaticism.

As he chanted the spell, the dark vortex gradually expanded, forming a black portal, from which a strong evil aura gushed out. A tall, distorted demon creature walked out of the portal, its eyes full of fanaticism and desire.

The demon creature emerged from the dark portal, tall and mighty, with twisted muscle lines and skin as black as burnt charcoal. Its face was chilling, with a pair of sharp horns extending from its forehead, like a symbol of the devil. Its evil eyes flashed a deep red light, full of fanaticism and desire.

The demonic creature opened its mouth, revealing a row of sharp teeth, each as sharp as a dagger. Its arms were long and thick, with forked fingers at the end that formed sharp claws, which could easily tear apart anything that stood in its way.

Its body is covered with black skin, but there are many bruises, scars and twisted patterns on the skin, as if they are traces left by evil forces on its body. The muscles of the demon creature are bulging with powerful force, and the tendons bulge on its body surface, making people feel an irresistible sense of oppression.

\"Billy Kaplan, you're playing with fire and getting burned!\" Wang shouted vigilantly.

The demon creature rushed towards Wang and others at such a fast speed that it was difficult to dodge. Nathan Hawke immediately activated his electrical energy ability, and arcs flashed around him, forming an electrical barrier to block the demon creature.

Kang quickly adjusted the mode of his nano armor, ready to meet the demon's attack. His nano armor released a more powerful blue light, and the weapon was ready.

The demonic creature opened its bloody mouth and let out a shrill roar. Dark magical energy gushed out of its mouth, forming a black energy ray that blasted towards Nathan Hawke's electrical barrier.

Nathan Hawke firmly controlled the electric energy barrier, arcs burst out, and intertwined with dark energy rays. The two powerful energies confronted each other, and the scene was extremely fierce.

Seeing this, Kang quickly rushed towards the demon creature, and the weapon of the nano armor drew a light arc, and started a fierce battle with the demon. The demon was powerful, but Kang relied on the power of the nano armor to barely resist the demon's attack.

Nathan Hawke stepped back to the two men and said to them, "I'll go deal with Billy Kaplan, and I'll leave this demon to you."

Kang heard what Nathan Hawke said and was about to speak immediately, but he was suddenly shocked and then said, "No problem."

"Leave it to us. You go deal with Billy Kaplan." Wang looked at the demonic creature vigilantly and echoed.
