I opened an adventurer's guild in another world.

Fireball is a very basic fire magic skill.

These are generally the most commonly used skills by low-level mages.

However, once a mage reaches the intermediate level, the [Fireball] spell will be phased out due to its low power.

Due to its high mana consumption, low power, and short range, not many people would train the [Fireball] spell to the sixth level.

With that energy, you might as well learn a sixth-tier spell, which is much more powerful than [Fireball].

However, the Fireball spell is a skill that Geng Qingxue particularly likes.

With the blessing of [Magic Amplification], Geng Qingxue's [Fireball] spell, which she had deliberately trained to the sixth rank, was no less powerful than the highest-ranking sixth-tier magic.

Moreover, such simple magic requires a short chanting time.

For Geng Qingxue, it was no different from an instant cast.

The consumption is also pitifully low.

With the response of [Magic Fountain], both staffs were cast simultaneously, shooting out ten fireballs per second. Geng Qingxue could keep shooting for several minutes without stopping.

Countless fireballs rained down on the undead army, blasting countless undead into pieces.

In the area covered by artillery fire, not to mention the undead dared not advance a single step.

Even the elven guards standing in front of Elsana retreated again and again.

He was afraid that if Geng Qingxue's hand trembled and she lost her grip on the staff, the fireball would fall on his head.

The most intense battle currently is between the Dream Thieves and the Undead Legion outside the Elf King's City.

However, in terms of attracting attention, the battlefield that retreated to the vicinity of the Tree of Life drew the attention of most of the powerful figures, even those at the god level.

"That woman, could she be a protector?"

One of the god-level skeletons looked at Geng Qingxue, then turned and charged towards her.

"Hey, hey, hey, where do you think you're going?"

A beautiful elf, as if from a painting, stood in front of the god-level skeleton, holding a blood-red giant sword in her hand, and said in a magnetic voice, "Let me dismember you and make soup from you."

Enraged by these words, the god-level skeleton roared, "Damn God Hunter, I'll twist your skull off and drink your brains!"

Besides this god-level skeleton, there are many other undead on the battlefield who want to cause trouble for Geng Qingxue.

But they were all stopped by the hunters and dream thieves.

"Roar~!"

A piercing, demonic sound entered Geng Qingxue's ears, causing her to instinctively cover them, which interrupted the casting of her [Fireball] spell.

As Geng Qingxue covered her ears and looked ahead, a huge bone dragon was flapping its bone wings and swooping down on her from mid-air.

Geng Qingxue's eyes narrowed. With her left hand, she continued to use the [Fireball] spell on the bone dragon to harass it, while with her right hand, she began to gather a large amount of magic power.

Scorching flames rose from above the magic crystal on the staff and began to swirl around Geng Qingxue.

With a cry, a giant firebird circled Geng Qingxue once before flying upwards.

Elisana looked up, her mouth agape, staring in shock at the dazzling firebird created by Geng Qingxue's magic.

"Eighth-tier secret technique - [Phoenix Blaze - Underworld Conquest]!"

The fire phoenix in the air cried out again, and the red flames on its body suddenly turned purple. Under Geng Qingxue's control, it rushed towards the flying ninth-tier bone dragon.

As it flew into the area filled with undead, the purple fire phoenix lowered its altitude.

Before the undead could even come into contact with the purple fire phoenix, their bones and flesh burned, turning to ashes after emitting mournful cries.

The ninth-tier bone dragon, relying on its magic immunity, had previously ignored the incoming [Fireball] spell.

At this moment, facing the charging Fire Phoenix, he simply crashed into it.

boom!

The bone dragon's body was instantly engulfed in purple flames, and each bone was burned to ash.

Thump!

The bone dragon, several tens of meters long, fell to the ground and fell apart.

"Wow, that's awesome, sister!"

Miriam rushed over from the battlefield outside the city, originally to support Geng Qingxue in dealing with the Bone Dragon.

Seeing the bone dragon instantly killed by Geng Qingxue's magic, Miriam kept praising, "The bone dragon's magical defense was ridiculously high! Your magic actually managed to kill that big guy instantly!"

Geng Qingxue wiped the sweat from her forehead and said to the White Dragon King beside her, "I have dealt with the undead quite a bit. This skill was developed by me and a lich. It was originally very effective against the undead."

Khrushchev, Khrushchev.

It refers to restraining the undead race of the underworld!

Geng Qingxue had one more thing she didn't say.

That means the Fire Phoenix's fire isn't ordinary fire, but rather the fire of the Fire Elemental King.

She had obtained the fire from the fire elemental spirit king summoned by Anno and sealed it in her staff.

No matter how strong the Bone Dragon's magic resistance is, it cannot withstand the [Phoenix Blaze], which targets the undead, uses a special flame as its core, and has four times the power.

After saying that, Geng Qingxue threw away the unsealed staff in her hand and took out a new staff that sealed the fire seed of the fire element spirit king.

"Be careful!"

Winnie suddenly appeared behind Geng Qingxue, shielding her from the attack of the Time Apostle.

The time-space apostle, now blocked, chuckled and said with a sinister expression, "The Protectors, as loopholes in this world, should all be eliminated!"
