As Rowling tore apart the magic scroll in her hand, an extremely strong white light began to spread around, and in the blink of an eye, the entire Silver Cliff City was enveloped in it.

When this extremely dazzling white light appeared, it immediately dispersed the death cloud that shrouded Rowling, and the death energy used to form the death cloud disintegrated under the action of this white light in an instant.

This kind of [Undead Slayer], which is specially used to deal with undead creatures, naturally has an extremely powerful effect in purifying death energy, even if it is a cloud of death condensed by death energy, it is also unable to make any resistance, and it is instantly dispersed by this white light.

Even the death energy that was originally shrouded in Silver Cliff City, when the spell of the undead killer appeared, it could not maintain its original form. The entire Silver Cliff City seems to have undergone a special change because of the arrival of this powerful spell.

At this moment, the ability of the undead killer to purify the energy of death is undoubtedly well reflected.

When the cloud of death unleashed by Reese came to Rowling's side and enveloped Rowling in it, Rowling did not hesitate to tear open the extremely powerful magic scroll.

Before tearing open the magic scroll, from the magic scroll in her hand, Rowling also felt a very special signal in her heart, as if she could change the spell recorded in the magic scroll according to her own wishes.

Just like when she cast the Hell Flame Magic Scroll before, Rowling was able to make certain changes to the Hell Flame magic recorded in the magic scroll according to her own needs, and at this time, the signal from her heart made Rowling understand that she could also make changes to this Undead Slayer magic scroll.

When she tore open the Hell Flame Magic Scroll before, Rowling was not very sure whether she had this extremely abnormal ability, but now, Rowling has finally confirmed that she has the ability to change the magic effect recorded in the magic scroll.

For Rowling, this very special ability, like her instinct, can be used without even exploring.

Under normal circumstances, Rowling might have felt extremely excited when she learned that she had this very special ability, but now, Rowling didn't care about it.

What Rowling had in mind was that only how to use this special ability could inflict the most damage on Reese.

Because she had already determined her own end in her heart, Rowling didn't care about the fact that she couldn't bear the undead killer either.

The way Rowling chose to change this undead killer was to strengthen the undead killer's purifying effect on death energy.

The undead killer cast by ordinary mages, because the spell itself can cover a wide area, the damage it can cause is relatively limited, and if the mage's own mental attributes are insufficient, it will be difficult to exert the true effect of the undead killer.

Because of this, when Rowling strengthened the purification effect of the undead killer, for the necromancer who had extremely strong death energy in his body, the spell of the undead killer was no longer as simple as a third-order magic.

Due to the extremely rich death energy in Silvercliff City, through the confrontation between the undead killer and the death energy, Rowling was able to make these changes to the undead killer.

If it weren't for the magical elements in the surrounding environment, which met Rowling's requirements for strengthening the magic of the Undead Slayer, it would be difficult for even Rowling with the ability to change magic forms to achieve this.

Previously, whether it was because of the attack of the cyclops or under the cloud of death transformed by Vita, the creatures that died in this area, their corpses, were undoubtedly affected by the death energy, but the degree of impact was different.

Under the illumination of this white light, at this time, this pale flame was also generated on the corpses of these creatures, purifying the death energy on their bodies.

This time, for the corpses of these dead creatures, this pale flame was not just an illusory form, but an entity, purifying their corpses, along with the death energy contained in them.

In her original position, Rowling could also feel the damage caused by the undead killer to herself.

Through her own perception, Rowling can realize that the life force in her body is passing rapidly, even if Rowling does not have some new wounds on her body because of the spell of the undead killer, Rowling can also realize that she cannot support herself for too long under the effect of the undead killer.

Compared to Reese on the side, Rowling's state was undoubtedly much better, and in Rowling's perception, she only felt a slight pain, not like the severe pain Reese felt.

Rowling knew that this might also be related to her own enhancement of the Undead Slayer.

The purifying effect that Rowling has strengthened about the undead killer is reflected in the necromancer's body, which will cause additional damage according to the concentration of death energy in their body.

The concentration of death energy in a necromancer's body is related to the level of spiritualism that the necromancer has, as well as the mana they have.

Due to the influence of spiritualism, the mana value possessed by the necromancer is extremely special, and the necromancer is able to convert the mana he has into death energy release.

In this case, the Necromancer's ability to purify death energy can also be reflected in the mana that the necromancer has, and the more mana the necromancer has, the more damage the Necromancer can do.

When Rowling strengthened the purification power of the Undead Slayer's magic in the Magic Scroll, the Undead Slayer was undoubtedly able to better affect the surrounding death energy.

Embodied in Reese, it is the pale flames that have always existed in him, and even Reese can only choose to endure the burning caused by these flames.

For ordinary undead creatures, the powerful undead killer magic can even ignite their soul fire directly, while for those necromancers, the undead killer may not be able to do this, but it can also ignite the death energy in their bodies.

In Rowling's body, these pale flames did not appear, and Rowling naturally did not feel the pain caused by the flames.

Since there is not much mana left in the body, for Rowling, the Undead Slayer will not cause additional purification damage, but the base damage of the Undead Slayer still needs to be fully borne by Rowling.
