In the dark cave, they could finally see a string of light. Merlin and the others walked for a while in the narrow cave before noticing a faint light not far in front of them.

This indicated that they were near the end of the cave. There might be more danger in front, so Merlin and Laurinka were not particularly happy about it. Instead, they became even more cautious.

Both gradually walked out of the passage and arrived at a large cavern with multiple gigantic rock pillars.

A dozen of Elemental Swordsmen and two Spell Casters who were barely breathing were tied on the rock pillars. As if they sensed the motion, a hint of surprise ran across the Spell Casters' faces. They opened their mouths wide but no words came out of it.

Merlin was shocked because he had guessed their identities. They would be Wizard Pario and Marshal Wharton sent by Donglin City. He did not expect to see them caught in the cave and became the way they were now.

"Swoosh!"

Suddenly, Merlin felt an outrageously strong Mind Power hovering over him. The strength of this Mind Power was similar to a Second-level spellCaster.

Merlin was overwhelmed with shock and quickly raised his head and looked for it. He found a tall altar in front of him and a skinny silver-haired old man stood there.

Other than his strong Mind Power, this silver-haired old man also gave a dangerous feeling to Merlin.

"Who are you?"

Merlin felt that this silver-haired old man was closely related to the Dark Vampire Bats outside of the cave.

The silver-haired old man did not answer. Then, Merlin saw two people walking out of the passage at the side. They were Wizard Holmes and Wizard Ryllis.

However, Wizard Holmes and Wizard Ryllis seemed a little messy at the moment. The runes on Holmes' robe were dark as if the runes were badly damaged. Meanwhile, Ryllis was pale as if she had gone through a life-and-death battle earlier.

"Hmm? Wizard Merlin, Wizard Laurinka, you're here as well?"

Holmes raised his head. When he saw Merlin and Laurinka, he was stunned, then shook his head. He exclaimed, "Fortunately, you didn't take our path just now. If you met the Dark Vampire Bat which was about to evolve into a Vampire Bat King, then it'll be a life-and-death situation for you! Ryllis and I didn't even mind using the First-level spell Scrolls we exchanged from the Resource Tower to annihilate it."

From Wizard Holmes' gaze, it seemed that he still shuddered at the thought of the Dark Vampire Bat he met in the passage.

Merlin seemed serious. He did not explain but he nudged Wizard Holmes to look at the altar.

Holmes and Wizard Ryllis followed Merlin's gaze and noticed that mysterious silver-haired old man on the altar and both became alerted immediately.

The silver-haired old man took a glance at Holmes and Merlin and sniggered. "Hehe. Both of you killed my babies. Nothing less expected of the genius Spell Casters in the Dark Magic Region! However, my babies will definitely love your meat. Haha…"

The silver-haired old man laughed as if he had gone mad.

"Two?"

Holmes thought for a while, then stared at Merlin with shock. He could not help but exclaimed, "You met the Dark Vampire Bat which was about to evolve into a Vampire Bat King as well?"

Laurinka naturally understood what Holmes was thinking. She took a complicated glance at Merlin, then replied in a low voice, "We met that strong Dark Vampire Bat as well but Wizard Merlin have dealt with it."

Holmes was surprised even if he knew that Merlin had Five-Elemental spells and was stronger than him. However, how did Merlin and Laurinka annihilate that strong Dark Vampire Bat without a casting tool?

Without waiting for Holmes questioning further, the silver-haired old man on the altar mumbled and pointed to the pool of blood below the altar.

"Come out, baby. Your meal is here. Kill them, eat their flesh. You'll become a true Vampire Bat King!"

As soon as the silver-haired old man finished his words, the pool of blood immediately bubbled. Slowly, a large, two-meter-tall Dark Vampire Bat came out of the pool of blood. Its whole body had almost taken up half of the pool of blood.

Looking at this strange Dark Vampire Bat, the silver-haired old man's gaze revealed a hint of crazy passion.

Merlin and Holmes took a deep breath and exchanged glances. They could see the shock in each other's eyes. The Aura of this large Dark Vampire Bat doubled than the one they met in the passage.

Moreover, its Aura appeared even more violent. Most importantly, thick blood vessels, bones, and flesh full of life could be seen on this Dark Vampire Bat. When they checked with their Mind Power, they could sense a weak living Aura from it.

An Elemental Monster did not have a living Aura as it was formed from rich Element. The ability to produce living Aura indicated that this Dark Vampire Bat had evolved into a true Elemental Being. Indeed, it was a terrifying Vampire Bat King!

The Dark Vampire Bat flew out of the pool of blood. Its large size brought a strong visual impact to everyone. However, when it revealed its whole body, Merlin and Holmes heaved a sigh of relief.

This was because they found that only half of this Dark Vampire Bat had given off a weak living Aura. Other parts did not have any sign of life. This showed that this Dark Vampire Bat had not completely evolved into an Elemental Being.

Nevertheless, it was still much stronger than the two Dark Vampire Bats they encountered in the passage.

"So, you're an ancient Shaman. You want to build a pool of blood and forcefully turn Dark Vampire Bats into Elemental Beings? It seems that you're the one who controlled those Dark Vampire Bats to suck living beings' blood dry in Donglin City."

Wizard Holmes revealed the identity of the silver-haired old man. This was the advantage he had as a disciple of a large Spell Caster family. At least he knew some of its secrets.

After hearing Wizard Holmes' words, Merlin instantly recalled some legends regarding the Shamans.

Before Spell Caster had appeared, the whole world was controlled by the ancient witches. There were many types of ancient witches. Some could tame beasts while some were good at producing weird potions. The potions of Spell Casters were mostly improvised from those of ancient witches.

Another unique type of ancient witches was Shamans. They neither tamed beasts nor produced potions. Instead, they specialized in rituals and prayers. After a long time had passed, this had greatly improved their Mind Power. Some Shamans even controlled all sorts of Elemental Monsters in the world with their strong Mind Power.

Moreover, they had a strange method to catalyze the evolution of Elemental Monsters into stronger Elemental Beings.

However, since the birth of Spell Casters who could control all sorts of Elements and held immense power, ancient witches had gradually disappeared.

This silver-haired old man might have received the legacy of Shaman by accident. Thus, he wanted to create an evil pool of blood and let Dark Vampire Bat evolve into Vampire Bat King.

"Someone actually still knows about Shaman. Hehe. Such a shame. What will happen even if you know? After I kill you, I'll leave the area under the Dark Magic Region's influence and wait for the Dark Vampire Bats to completely evolve into Elemental Beings! Baby, kill them!"

The silver-haired old man wore a cruel look and pointed at Merlin and Holmes. In an instant, the strong Dark Vampire Bat's sharp gaze immediately locked onto Merlin and Holmes.
