Reese noticed that although the sea of fire in front of him had dissipated, the shock it produced was still in Reese's heart.

Reese, who had been out of the fire early in the morning, naturally saw the changes that had taken place in this area.

The sea of fire was not accompanied by a violent explosion like the previous fireballs, but it was still able to kill all the necromancers in it, and Rees knew that it should have something to do with the nature of the spell.

The moment the sea of fire was generated, under the impact of the magic element, these necromancers completely lost their vitality in their bodies, and the subsequent flames were only burned on the corpses of these necromancers.

Although Rees moved a long distance by teleporting, he could still clearly feel the scorching waves around him in this position, and Reese naturally had a grasp of the temperature in the center of the sea of fire.

Even Reese, who was out of the spell's range of effect, couldn't help but be shocked by the effect of the spell.

The appearance of the sea of fire did not last long before it stopped due to the consumption of magical elements. At this time, the surrounding magical elements were gradually returning to calm, and this sea of fire naturally ceased to exist, but the impact it caused was irreversible.

It was only then that Rees could notice the full picture of the area where the sea of fire existed.

Under the scorching flames, the corpses of these necromancers were long out of shape, covered with layers of pitch-black charcoal. Even Reese couldn't match these corpses with the necromancers before.

According to his own understanding of magic, Rees understands that this spell that suddenly appeared and killed all necromancers was at least above the level of fourth-order magic, and only real high-level mages were qualified to learn this spell.

Although Rees has the strength of the fifth order, he does not have enough wisdom skills, and even if the complete fourth-order magic casting method appears in front of Reese's eyes, it may take Rees a few months to master this fourth-order magic.

Due to his status as a necromancer, it is difficult for Rees to choose magic to study magic in the magic guild like an ordinary mage, and if he wants to learn any kind of magic, Rees can only go through the channels of the spirit guild or ask other necromancers for advice, not to mention these extremely powerful fourth-order magic.

At this point, Reece himself also understands that for those powerful high-level magic, Rees has long ceased to be as eager as ordinary mages, and has instead devoted all his energy to the study of necromancy.

But at this time, what Rees didn't expect was that he would be able to witness the impact of this high-level magic in Silver Cliff City.

Rees knew that if he hadn't reacted in time and escaped from the area formed by the sea of fire by teleporting, then by now, his fate would be no different from those corpses on the ground.

Reese may be a necromancer, but he still knows a lot about spells. Through the scene created at the moment when the sea of fire was formed, as well as the abnormal changes in the surrounding magic elements, Rees immediately recognized the type of fourth-order magic it was in.

In Reese's opinion, the sea of fire that appeared before should belong to the fourth-order fire magic, a spell casting method of Hell Flame.

For high-level mages, when they cast a spell, they are able to make some changes to the spell they are about to cast, depending on their needs.

This may not be obvious for low-tier magics that are monotonous, as it is difficult to make spells break through the limits of the rank, no matter how many changes are made to spells. But for those extremely complex, high-level spells, this is undoubtedly extremely obvious.

Any change to a spell requires a high level of proficiency on the part of the mage himself. Few mages are capable of doing this, except for high-level mages.

In Reese's opinion, the Infernal Flame that appeared before belonged to such a situation.

According to Reese's understanding, when the regular hellfire is cast, it must be accompanied by a steady stream of explosions, and then such a sea of fire will be formed, but at this time, this hellish flame obviously does not follow this form, but directly forms such a sea of fire, harming the necromancer in it.

Reese didn't believe that Rowling, who had appeared in front of him, could cast the spell of Hellflame, and that he would change the situation of the spell and turn the area into a sea of fire.

Reece knew that the appearance of the Infernal Flame must have been something special used by Rowling.

After this sea of fire caused by the flames of hell, the death energy that originally enveloped the entire Silver Cliff City was also dispelled a lot at this time.

Apparently under the influence of the magical element, the cloud of death that Reece had cast had completely dissipated, revealing what it was in before.

In Reese's line of sight, just behind the sea of fire, where the clouds of death had been, Rowling's figure was there, looking to see the situation.

Reese noticed that there was a look of extreme remorse on Rowling's face, as if something had not developed as she had expected.

Obviously, the infernal flame that enveloped a large area before came from Rowling's hand. Rees didn't understand how Rowling did it, but at this point, Rees was able to confirm it by the look on Rowling's face.

Although Reese was a little sad about the death of these necromancers around him, there was only a trace of sadness in his heart, and Rees knew that if he hadn't discovered something wrong before the hellfire appeared, then his current fate would be no different from the charred corpses of these blackened necromancers around him.

At this time, looking at Rowling in front of her, Reese finally stopped holding her hand and began to cast spells on it.

Having had had the experience of the previous time, Rees already knew that Rowling had some special means to resist the erosion of the clouds of death.

This time, instead of casting the Cloud of Death, Rees chose some extremely common spells to attack Rowling.

Through the remorse on Rowling's face, Reece had already guessed that it was difficult for Rowling to pose any threat to herself at this time.

With the experience of the appearance of Hell Flame before, Reese at this time has completely regarded Rowling as a mage of the same rank, but this mage does not have much mana.
