"Zero Degree Ice Seal!"

A white scroll appeared on Wizard Ryllis' hand and she immediately cast it. Zero Degree Ice Seal was a First-level Ice-type Defensive spell. Once it was released, the temperature surrounding the Spell Caster would immediately drop to an unbelievable level. Any attack would be weakened once the attack entered the region of Zero Degree Ice Seal.

"Hiss!"

After Darkness Rays entered Ryllis' region of Zero Degree Ice Seal, it was immediately weakened by half. However, a small portion still penetrated the defense of Zero Degree Ice Seal and hit Ryllis' right shoulder.

Meanwhile, another ray headed straight toward Laurinka.

Laurinka was overwhelmed with shock but she did not panic. A yellow shield carved with all sorts of mysterious runes appeared in her hand. This was a pure defensive casting tool she had exchanged at the Resource Tower with a large number of contribution points. Initially, she had thought that she would not need this shield as she did not expect to face such a life-and-death crisis. Left with no other choices, she had to use the Runic Shield.

"Bang!"

After an intense clash, the runes on the shield gleamed, then disappeared. Then, the shield began to crumble and finally turned into smithereens. Laurinka's face immediately turned pale. Even with the protection of the Runic Shield, she was still gravely injured. She was barely hanging on now and thankfully she did not pass out.

In the blink of an eye, the tables were turned. Ryllis and Laurinka were injured and had lost their combat ability. To be able to protect themselves indicated that they had already done their preparation well.

However, this did not indicate that Ryllis and Laurinka were weak. They had received systematic learning in the Dark Magic Region and the Spell Models they constructed were also stable. In terms of ability, they were definitely better than most roaming Wizards.

This time, they faced a Dark Vampire Bat which had completed half of its evolution. Darkness Rays, the spell which it released, contained a force that came close to that of a Second-level spell. It was only expected that they were unable to defend against it.

"Hehe. Just be obedient and be my babies' meal…"

The silver-haired old man was satisfied with the Dark Vampire Bat's performance. He had overcome many difficulties and spent a dozen years for this, hiding in many places and building the pool of blood secretly under the influence of the spell casters' organizations. Once he noticed any changes that attracted the attention of the spell casters' organizations, he would immediately leave.

While he was hiding, he let the Dark Vampire Bat gradually evolve. Now, it had completed half of its evolution. Once he killed these Spell Casters from the Dark Magic Region, he would leave Donglin City and build another pool of blood at another place. Soon, he might be able to let the Dark Vampire Bat to fully evolve into a Vampire Bat King.

"Rumble!"

Wizard Holmes' Earth Cage was completely destroyed by the Dark Vampire Bat. A red shine flashed across the Dark Vampire Bat's body, then its speed increased significantly, heading toward Wizard Holmes.

"Bang! Bang! Bang!"

The Dark Vampire Bat ignored the attack of the spells and frantically crashed into Wizard Holmes. Even if the robe on Wizard Holmes was great for defense, it also seemed rather difficult to hold on under the fierce attack of the Dark Vampire Bat.

After all, any casting tool had a limit in usage, including this Runic Robe. Until the runes on it had been depleted, the robe would no longer have any effect.

In another round of fierce attack, Wizard Holmes could not defend against it at all. He was already feeling dizzy and nonplussed from the attack, so he could not retaliate effectively against the Dark Vampire Bat.

"Swoosh!"

Right at this time, Merlin's figure flashed as he had cast Gale and saved Wizard Holmes.

"Wizard Holmes, we must gather all strengths now. Otherwise, I'm afraid we'll all be in a deep trouble."

Merlin lowered his voice and said in a serious tone.

Wizard Holmes wore a dark expression. He had never been in such a tight corner before, but this Dark Vampire Bat had rendered him out of ideas and had fallen into a disadvantaged position.

"Wizard Merlin, what do you think?"

At this time, the prideful Wizard Holmes had no choice but to admit that Merlin was their only hope now.

Merlin shot a thoughtful glance at the Dark Vampire Bat. He caressed the Bell Pendant he wore on his neck. If there was a huge number of Large Fireballs stored in the Bell Pendant now, he would not be in such a loss facing the Dark Vampire Bat.

Merlin took a deep breath and suppressed the messy thoughts in his mind. Although he no longer had the Bell Pendant, his current strength was far stronger than before. Thus, Merlin said, "Wizard Holmes, I need the Runic Robe you're wearing!"

Holmes stiffened slightly. This Runic Robe was the casting tool used as a last resort for protection. If he gave it to Merlin, he would be in a great danger.

However, Merlin appeared determined as if he was ready for the final battle. Holmes gritted his teeth and took off the robe. As he handed it to Merlin, he said, "Wizard Merlin, if you lose here, we're all going to die."

Merlin nodded solemnly. Then, he wore Wizard Holmes' robe. Instantly, he sensed a magical force covering his entire body. This was the force of runes on the robe. However, after the Dark Vampire Bat had hit it many times, the power of runes could not hold on for long.

"I can't kill the Dark Vampire Bat no matter what. But it's not impossible to kill the silver-haired old man who's controlling the Dark Vampire Bat!"

Merlin squinted his eyes and shot a glance at the Dark Vampire Bat and the silver-haired old man. This Dark Vampire Bat who was halfway in evolution was simply too strong. Even his Large Frost did not cause much damage to it.

Thus, to leave this place alive, he would have to kill the Shaman, the silver-haired old man as he held absolute control over the Dark Vampire Bat. Once the Shaman was dead and his Mind Power broke apart, then the Elemental Monster he controlled would die with him.

This was also the most obvious weakness of the Shaman.

However, Merlin understood that the silver-haired old man would order his Dark Vampire Bat to attack frantically fearlessly. It was still unknown whether he could withstand the fierce attacks of the Dark Vampire Bat. This was the most important reason why Merlin needed Holmes' robe.

"Swoosh!"

Merlin moved and strong fluctuation of Wind Element appeared with him as he cast Gale. Facing the Dark Vampire Bat, he fiercely cast all his spells without reserving his Magic Power.

"Fireball!"

One after another, fireballs poured on the Dark Vampire Bat frantically like raindrops, including gigantic fireballs.

Along with the improvement of Merlin's Mind Power, his speed to cast spells had reached the extreme. The spells were almost cast in an instant. Immediately, forty fireballs were released.

With Merlin's accumulation now, he could cast Fireball and Frost for about fifty times at once. Thus, Merlin exhausted a large amount of Magic Power in Fireball's Spell Model instantly.

"Explode!"

Numerous fireballs exploded and the heatwave spread throughout the cave. However, Merlin knew that these fireballs could not hurt the Dark Vampire Bat. His aim was to simply hold down the Dark Vampire Bat for a moment.

Therefore, other than Fireball, Merlin also cast the strengthened version of Thunderbolt Net and countless Frosts. He threw the spells, aiming at the Dark Vampire Bat.

It was such a horrifying attack. Only the spells cast by Merlin could be seen throughout the cave. Even Wizard Holmes was wide-mouthed, staring at the scene before him.

Now, he knew how huge the difference truly was between him and Merlin!

The silver-haired old man stood at the tall altar, watching as Merlin cast his spells like a thunderstorm. Although he also seemed surprised at the situation, he did not worry at all. He knew that these attacks did not account much to the Dark Vampire Bat.

"Hehe. Even if you exhaust your Magic Power, it doesn't make any difference!"

However, as soon as the silver-haired old man finished his words, he realized in horror, that Merlin revealed a smile on his face. He saw that Merlin quickly turned around and dashed toward him.

"Not good! His aim is me!"

The silver-haired old man had just realized Merlin's true intention. He immediately controlled the Dark Vampire Bat to gather Darkness Element as preparation to cast Darkness Rays.

"Swoosh!"

Merlin's speed, in fact, multiplied. The fluctuation of Wind Element on him almost reached the extreme. This was also the first time Merlin cast the strengthened version of Gale. At this moment, his aim was to bring an unexpected turn of event!
