"Kill him."

Without saying anything further, both moved.

"Swoosh."

Wizard Jason's white robe moved without the presence of wind. Bundles of holy light were shot from his hands as if they were raindrops and five pillars of light flew out in the blink of an eye.

These five pillars of light were the Zero-level spell Holy Light Bolt released by Wizard Jason. Every Holy Light Bolt had immense strength. Even Old Wilson's specially tailored armor could not defend against Holy Light Bolt's multiple attacks.

Merlin also refused to admit being inferior. His Mind Power suddenly stimulated the Fireball's Spell Model in his Awareness. Suddenly, five fist-like fireballs floated beside him.

"Go!"

Merlin's fingers simply pointed and the fireballs directly clashed into Wizard Jason's Holy Light Bolt. In red and white, both Zero-level spells began to clash.

"Bang! Bang! Bang!"

The clashing sounds resembled the rumbling of thunder, causing everyone in the hall to temporarily lose their hearing.

The terrifying thing was the flame and holy light that dispersed in all direction after the clash of spells. They had destroyed everything they met directly, almost as if they could do it easily.

In a short while, the whole hall was in a mess. Wooden debris was scattered all around the floor, and even the bluestone bricks had turned charred black.

"Go. We can't stay here any longer!" Old Wilson said in a deep voice and waved his hands and brought his knights out from the hall quickly.

Augustin, Vingult, and others were the same. They had quickly gone out of the hall. If they were slightly touched by the remaining force of the spells, they would have to pay a heavy price.

In the blink of an eye, the whole hall had been vacated. Only Merlin and Wizard Jason were still facing each other.

"Your spell is even stronger than the evil heretic!"

Wizard Jason had an aghast expression. Merlin and he had only tested each other earlier. Through the clash earlier, Wizard Jason found that Merlin's Magic Power was greatly powerful. It was even about the same as old man Etha back then, so he was extremely shocked by this fact.

"Wizard Jason, where's your First-level spell? If you don't cast your First-level spell now, I'm afraid you don't have the chance to do so anymore!" Merlin appeared calm. He knew Wizard Jason was a true First-level spell Caster! Old man Etha had died from Wizard Jason's First-level spell back then.

Thus, Merlin was very cautious against Wizard Jason's First-level spell.

"First-level spell? heretic, even a Zero-level spell is enough to deal with you!"

Wizard Jason shot him a haughty look. A thicker white light began to emit from his body. This was a sight that Light Element was rapidly gathering in him.

Merlin's expression changed. As a First-level spell Caster, Wizard Jason was obviously stronger than Merlin in terms of recovery speed of Magic Power and Mind Power. If it was a duel that would exhaust Magic Power like this, Merlin would be at a disadvantage.

Therefore, Merlin naturally wanted to finish the battle as quickly as possible.

"Frost!" Merlin suddenly cast Frost, the second spell he had grasped recently!

"Ka-chak, ka-chak."

Almost as soon as Merlin's voice dropped, a chilly wind directly engulfed Wizard Jason. Ice crystals instantaneously appeared on Wizard Jason's body, completely freezing his lower half body.

This sort of Binding-type spell, albeit not strong in power, had a strong binding ability. Merlin even cast Frost three times to secure the bind on Wizard Jason.

Three Frosts were already the limit Merlin had of casting normal Frost. Of course, after three Frosts, Merlin still had a chance of casting a Large Frost.

However, in the current situation, three Frosts were enough to bind Wizard Spell. He did not need to waste his precious Large Frost.

After binding Wizard Jason, Merlin pointed at Wizard Jason with both hands and performed his strongest spell.

"Large Fireball!"

"Voom!"

A gigantic fireball appeared out of nowhere, emitting scorching heat as if distorting the air.

Merlin had almost cast Frost and Large Fireball at once, so Wizard Jason had changed his expression as soon as he realized he was bound.

"Explode!"

Merlin showed a slight smile. Wizard Jason did not even have the chance to cast his First-level spell. The body of a Spell Caster was usually weaker, only slightly stronger than Normies.

Facing the Large Fireball which was way stronger than the normal Zero-level spell, Wizard Jason had no way of blocking it.

"Boom!"

The gigantic fireball exploded. Terrifying flame engulfed Wizard Jason's body. The whole hall was filled with ferocious flame. The inside of the gigantic fireball released by the Large Fireball was not stable to begin with, so its impact could cover about ten meters in radius once exploded.

Even Merlin had to retreat from the hall hurriedly. A scorching fiery air came straight at him and almost pushed him out of the hall.

"Ka-chak."

Cracks that resembled spider webs began to appear on the sturdy white walls in the hall. They were formed from the direct impact of the explosion of Merlin's Large Fireball.

Everyone was gawking at the hall with a wide mouth. That furiously burning flame was like the flame of a death god. Everyone felt a chill down their spine looking at it.

"Too strong… Evil heretic? Having similar strength with the church's Wizard. He's simply too strong!"

Castellan Augustin sneaked a glance at Merlin. The strength Merlin and Wizard Jason showed had gone far beyond his understanding. With such terrifying strength, even thousands of knights could not stop Merlin alone.

The flame in the hall slowly disappeared. Merlin who had just heaved a sigh of relief had changed his expression suddenly.

Others might not be able to see the situation in the hall but Merlin's Mind Power could see it clearly. He could faintly sense that the Light Element was still gathering rapidly in the hall.

"Hu…"

A gust of chilly wind blew from outside the castle, blowing away the dust in the hall. A figure stood before everyone's sight once again.

"Not dead?"

The dust had already dissipated in the hall, so everyone could clearly see Wizard Jason. The ice crystals on him were already gone since long ago. The crazy explosion just now seemed to have no effect on Wizard Jason at all. Even his white robe did not have a speck of dust on it.
