"Boom!"

Cook strode toward Merilung. As his right foot stepped on the ground, it was as if the whole ground shook. At the same time, Cook raised his sword. When he came to a few meters away from Merilung, he shouted and slashed his sword at Merilung.

"Swoosh."

A ball of bright light flashed. As soon as it appeared, it seemed to bring a biting cold with it. The snowflakes falling from the sky were immediately frozen because of it.

"Ka-chak. Ka-chak."

Cook's sword suddenly became larger in size and a thick layer of solid ice crystals laid on top of it. With his enormous strength, this sword which was almost made of ice crystals suddenly exploded. Countless ice debris flew toward Merilung like raindrops.

Cook was an Ice Swordsman and he had demonstrated his ability as a Fifth-level Elemental Swordsman perfectly. He was able to bring out the power of Ice Element from a distance.

This was the substantial difference between an intermediate and a beginner Elemental Swordsman. Other than possessing Aura, an intermediate Elemental Swordsman could bring out the elemental force from a distance, causing damage to the opponent.

In a way, an intermediate Elemental Swordsman had the ability to hurt a Spell Caster!

Cook was the same. He was a Fifth-level Elemental Swordsman. If any of his ice debris had hit Merilung, it would cause great damage to Merilung.

Even a slight hit could injure Merilung badly. After all, a Spell Caster's body was only slightly better than Normies.

From Cook's Aura which seemed to solidify to releasing thousands of ice debris, everything was done swiftly in one movement. His strength as a Fifth-level Elemental Swordsman was demonstrated perfectly.

However, facing Cook's fierce attack, Merilung simply dodged to the back quickly, then pointed both his hands forward.

"Swish, swish, swish."

Gusts of wind whistled by and three gigantic flames flew up, forming a large sea of fire. It blocked in front of Merilung and the ice debris could not penetrate this sea of flame which Merilung created.

However, Cook's attack was not finished. His muscular body dashed forward in a sudden movement. As he waved his sword, a chilly aura of few meters long flew from the sword toward Merilung.

"Ice Seal!"

This icy aura was the Ice Element Cook had accumulated in his body for approximately twenty years. It exploded completely and the terrifying air had frozen everything in its way.

Cook had relied on such sudden breakout previously to seal the movement of the Icelandic Wolf, then killing the fierce beast in the end.

"Swoosh."

Merilung's figure swayed and he had reached behind Cook in the blink of an eye. Cook had missed his hit. The enormous inertia had almost knocked Cook out of balance.

"D*mn. Too fast!"

Upon seeing Merilung's terrifying speed, Cook could not help but cursed. Even the Icelandic Wolf he faced before did not have such quick speed.

Merilung had reached behind Cook and without a moment of hesitation, he directly created a ball of flame. The scorching heat had given Cook a shock. Without having the time to think, he retaliated by slashing his sword. Ice Element turned into icy aura and fought against Merilung's flame.

"Cook, this is just the beginning!"

Merilung gave a grim laugh as the Wind Element on his body kept vibrating. He then released his Wind-type spell again. His figure flashed like a ghost to the point that Cook could only hear the whistling wind in his ears.

During Cook and Merilung's short battle, Merilung only utilized Fire-type and Wind-type spell to take advantage of the situation battling Cook. These two spells were only Zero-level spells.

"Merilung is still an Entrance-level Spell Caster!"

After observing for a long time, Merlin roughly knew Merilung's current stage. He had not reached the stage of First-level spell Caster. However, he was extremely experienced in casting spells. The combination of two spells had created a rather surprising effect in battle.

"I caught you. Haha. Merilung, die!"

Cook's face was pumped red right now. He was completely in a disadvantaged situation. Since Merilung's speed was too quick, he could not pinpoint Merilung's exact location at all. He was very passive.

Thus, when Cook sensed that Merilung was behind him, he did not care about the scorching heat behind him and defended against Merilung's spell directly with his arms.

"Tsk, tsk, tsk."

The ferocious flame and white chilly aura kept interweaving while half of Cook's arm was in the middle of the flame. Thus, even if Cook was strong and had covered his arm with Aura, he was still burnt and injured by the flame. His previously white skin had instantly turned charred black.

Enduring great pain, Cook had finally pinpointed Merilung's location. He had grasped the chance to seal Merilung's movement at the cost of his arm's injuries.

The chilly Aura in Cook's body immediately froze and Merilung's figure paused a little. The latter was obviously affected by the Ice Element released by Cook.

"Crossbow, do it!"

Cook howled loudly with all his might.

Cook had arranged many crossbows in the castle. Their aim was to eliminate Merilung. After all, without special casting tool or scroll, a beginner Spell Caster could be easily killed by a crossbow that had strong penetrating power.

"Swoosh, swoosh."

Dozens of black arrows were shot silently toward Merilung under the dark sky.

Cook had retreated beforehand and jumped away from the attacking region of the arrows. His right hand which was burnt by the flame was still trembling but a hint of a smile had escaped from Cook's face.

Many arrows were shot. No matter how quick Merilung could be, he had no way of dodging the arrows. Once he was hit by an arrow, Merilung would suffer great damage because of it.

"Bang, bang, bang."

The sound of numerous arrows colliding rang. It sounded as if the arrows had hit the wall and Cook's expression changed. The smile on his face gradually disappeared.

"He's not dead?" Cook mumbled to himself softly.

These arrows were all shot from crossbows. Even he could not be sure that he could get out of the attack easily.

"Phew…"

A gust of wind blew. A figure slowly stood up in the middle of the region where the arrows were most dense under the dark sky.

Merilung was not dead! Around him, rows of hard cob walls appeared without knowing when they had appeared, forming an unbreakable defense line for Merilung.

"Earth-type spell! Three Spell Models. Merilung possesses all the conditions required to become a First-level spell Caster…"

Merlin's current look had turned extremely serious. He stared closely at Merilung. Being able to create three Spell Models showed that Merilung had possessed the conditions required to become a First-level spell Caster. However, Merilung was still an Entrance-level Spell Caster. There must be some unknown reasons for this.

Merlin shot a glance at the black-robed old man beside him unknowingly. He found that the old man appeared calm as if he was not surprised about this at all.
