As compared to Holmes, Ryllis and Laurinka who were more familiar about Five-Elemental Spell Caster, Capace, Catherine, and even Wizard Danbe stared at Merlin with a dumbfounded look. They watched him as he ma.s.sacred the Dark Vampire Bats without much difficulties and obstructions. No matter how many Dark Vampire Bats there were, they would not be able to threaten Merlin at all.

"Is this the true strength of a Spell Caster? Wizard Merlin is too strong… Stronger than anyone I've seen!"

Capace exclaimed sincerely from his heart.

Wizard Danbe simply took a glance at Wizard Holmes, then he shook his head slightly. Initially, he had thought Wizard Holmes was the strongest amongst them but Merlin had now shown his true strength. Those troublesome Dark Vampire Bats could not cause any harm to Merlin at all.

Thus, he just realized that Merlin was the strongest amongst them.

"Kachak."

Merlin again froze another Dark Vampire Bat. As he cast Thunderbolt Net, he kept casting his Frost as well. He was definitely in a triumphant state now. It seemed like those extremely troublesome Dark Vampire Bats had no way of harming him at all.

This was a single-sided ma.s.sacre! However, the only thing Merlin was worried about was a large number of these Dark Vampire Bats. His Frost was not a large-scale offensive spell. If he killed them one by one, even if he depleted all his Magic Power, he could not finish killing the Dark Vampire Bats at all.

Thus, Merlin looked at Wizard Holmes and shouted, "Wizard Holmes, these Dark Vampire Bats are all paralyzed by my Thunderbolt Net. It's most suitable for you to cast Explosive Ice now."

Holmes came to his senses. He glanced at Merlin with a complicated look. Even though he did not think that Merlin had the chance of becoming a First-level spell Caster, it was the truth that Merlin was stronger than him now.

However, Holmes did not hesitate. He knew that all these Dark Vampire Bats were not something him or Merlin could deal with alone. With the paralyzing effect of Merlin's Thunderbolt Net on the Dark Vampire Bats, his Explosive Ice could bring the most outstanding result.

"Bang! Bang! Bang!"

Wizard Holmes cast nearly ten Explosive Ice at once. Suddenly, a whole flock of Dark Vampire Bats in front of him were blasted into pieces and fell on a large area of empty s.p.a.ce.

"Screech!"

A series of sharp noises came from the caves again. The Dark Vampire Bats which were not shrouded by Merlin's Thunderbolt Net immediately turned around and flew into the caves.

Merlin had continuously cast Thunderbolt Net multiple times. The consumption of his Magic Power was overwhelming. After all, he had only just constructed Thunderbolt Net not long ago. Even if he used a Darkness elemental crystal stone to acc.u.mulate his Magic Power, he could only continuously cast the spell for about twenty times.

Thus, when he saw these Dark Vampire Bats were retreating, he stopped casting Thunderbolt Net.

The Thunderbolt Net resided, and the flock of Dark Vampire bats did not attack Merlin and the others. They directly flew into the dark caves and disappeared completely in the blink of an eye.

Wizard Holmes gazed at the caves behind him and thought for some time. He seemed to be a little hesitant.

However, he made a decision soon as he said to Merlin and the others, "There are two caves here. We'll divide ourselves into two teams. Ryllis and I will be in a team and enter from the left cave. The rest will form the other team and enter from the right cave."

Merlin and Holmes were not from the same tower. If it was not for this mission, they would not know each other, so Holmes and Ryllis forming a group was expected of him.

After all, if they encountered true danger, Holmes would only stick together with Ryllis.

Laurinka and Merlin exchanged a glance, then nodded as an acknowledgment to Holmes' arrangement.

"Alright. If that's the case, we'll make a move first."

Wizard Holmes brought Ryllis and dived into the left cave directly.

Merlin glanced at Capace and Catherine as he frowned. "It's very dangerous in there. You can't help much with your ability, so just stay out here."

However, Catherine quickly replied, "Wizard Merlin, Father is also in there, so we'll follow you in there. We'll be at the back and we won't bring you any trouble."

Capace was more mature. He initially wanted to listen to Merlin's arrangement and stayed out here, but Catherine had already answered Merlin. He had no choice, so he only set his gaze toward Merlin.

Merlin frowned. Of course, he knew the eccentric Catherine only wanted to enter out of curiosity. These two were not that strong but they were good at attracting trouble.

Merlin was a little unhappy and said coldly, "We may encounter some danger in there. I can save you once or twice, but I may not be able to save you a third time. If you want to enter with us, then stay at the back."

After saying that, Merlin no longer cared about Capace and Catherine and directly entered the right cave.

In the deepest part of the dark caves, there was a s.p.a.cious stone room where a tall altar was built. At this moment, a skinny, silver-haired old man was standing at the altar.

The silver-haired old man was currently frowning as he stared at a large puddle under the altar. This was a puddle of bright red blood, giving off a thick b.l.o.o.d.y stench.

Moreover, it appeared like something was hidden under the pool of blood. The surface of the pool of blood resembled a boiling water surface, perpetually forming blood bubbles.

"Not enough. It still needs about a thousand persons' fresh blood."

The silver-haired old man mumbled softly. Suddenly, he furrowed his eyebrows and raised his head as if he had just noticed something.

"So, the Dark Magic Region still send people here? It's almost done anyway. Three months... The reaction of the Dark Magic Region is too slow… After I kill these Spell Casters, I should change a location."

The silver-haired old man muttered to himself. Then, his expression turned gruesome and pointed at a dozen pillars below him.

On each pillar, a person was tied to it. All his limbs were cruelly nailed on the stone pillar but the odd thing was that there was not a single drop of blood on their injuries.

"Swoos.h.!.+"

The old man's emaciated finger pointed to one of the stone pillars. Instantaneously, a Dark Vampire Bat of a larger size appeared and held the person on the pillar and threw him into the pool of blood.

"Arrrghhh!"

The person who was thrown into the pool of blood kept letting out fearful cries. However, his cries were of no use as he rapidly sunk into the pool of blood.

"Hehe, my babies. Come out."

The silver-haired old man muttered to himself. His extensive Mind Power directly extended into the pool of blood.

"Bloop... Bloop…"

Soon, the pool of blood came to a boil. Suddenly, two gigantic Dark Vampire Bats with b.l.o.o.d.y red bodies flew out from the pool of blood.

"My babies, go. Your meal is here. You'll be satisfied with them."

Two extraordinary Dark Vampire Bats let out a screech, then quickly flew into the two dark caves respectively…
