The Evil God Summoned by the Saintess

Boom!

A massive light sphere slammed into the fortress shield, triggering a violent explosion.

The members of the Law Enforcement Knight Order stood in a patterned formation, with several holy lines connecting each person, linking them all together.

In the sky, a huge flying warship emitted holy light, runes flashing around its body.

Numerous Tier Four and Tier Five Mages flew in the air, silently observing the battle situation.

"The Dawn War Airship, possessing terrifying firepower, consumes enormous amounts of magic power, and can only be powered by Pure Magic Crystals... It’s only deployed in times of war, and they brought it here?" Blake clicked his tongue in wonder.

Melina smiled slightly, "Exterminating heresy is as grave as war. The war airship is just sitting there if unused; it’s better to deploy it and show the heretics our resolve."

Blake curiously asked, "How did the Holy Master come to approve the use of such a destructive weapon?"

"Originally, it wasn’t approved." Melina pondered for a moment and shook her head, "I don’t know why, but suddenly he approved it."

Speaking of it, Melina felt a bit regretful, "However, he only provided me with one Pure Magic Crystal. The rest are Advanced Magic Crystals; I have to use them sparingly."

Blake suggested, "You actually don’t need to be frugal; you can substitute as the Pure Magic Crystal."

Melina glanced at him, "I think you’re more suited for that."

Blake laughed and looked at the heretics continuously emerging from the Deep Sea Mutual Aid Association.

"There’s news from the camp. The pollution is spreading, and it’s clear what the Deep Sea Mutual Aid Association intends."

Melina nodded, "Now it’s up to Hilia. The chance is slim."

"Prepare for the pollution spread in the Golden Apple Stone Forest. It’s just the pollution of one region, not enough to plunge the world into catastrophe again."

Melina nodded, remaining silent.

They charged forward, collaborating with the war airship to suppress, forcing the leader of the Deep Sea Mutual Aid Association to confront them.

Rumble!

A massive magic puppet emerged, engaging in combat with the two of them.

In a corner unnoticed by everyone, Hilia used the slight fissure caused by the warship bombardment to sneak into the Deep Sea Fortress.

The mastery-level Disguise Skill turned Hilia into a shadow, making her hard to detect.

The Deep Sea Fortress was surrounded by high walls, resembling a micro-city constructed around the central fortress castle.

Boom!

An intense explosion echoed from above, and Hilia looked up, feeling a bit concerned.

"Such fierce firepower, hope the fortress isn’t breached by the Law Enforcement Knight Order before I get inside the castle."

Rose’s shadow appeared next to her, smiling, "That’s possible, so hurry up."

Hilia nodded and ran quickly past squad after squad of heretics toward the central fortress.

From the sky, the Deep Sea Fortress didn’t seem large, but from the ground, running gradually revealed its vastness.

At least it stretched for several kilometers.

With Swift Movement Skill and Light Body Technique boosting her, Hilia deftly dodged heretics and the stray magical impacts falling from the sky.

Soon, she arrived before the towering fortress.

This fortress’s central stronghold wasn’t particularly tall, only tens of meters higher than the surrounding structures, with an overall height under 200 meters.

Nevertheless, from below, it appeared quite tall; standing underneath it, one felt like an ant.

"Such a massive castle, without clues, it’s hard to find the authority key before the battle ends..."

Hilia felt the ongoing rumblings from above, generating a sense of urgency.

Rose said, "Why not put yourself in another’s shoes? Where might such a thing be kept?"

"Surely, in the most securely guarded place... Speaking of which, I felt the whole Golden Apple Stone Forest array seemed to activate briefly earlier, might have been an illusion."

"It’s not." Rose said, "The Deep Sea has already removed the array’s restraint on the Demonic Qi pollution, and now, massive amounts of pollution are spreading outward."

"So decisive." Hilia was startled, quickly entering the fortress.

At this moment, a team approached.

Hilia quickly hid behind a nearby pillar.

The team paused as they passed, the leading mage looked puzzled towards the pillar where Hilia was hiding.

Boom!

A thunderous boom shook the ground.

"Hurry, hurry to support, don’t stop."

The voices of other heretics came, urging the team to leave quickly.

Hilia patted her chest, "I got startled, it was actually a Tier Four Mage, if a Tier Four Mage can detect me, if it were a Tier Five..."

Hilia didn’t dare continue the thought, afraid of jinxing herself.

"Can’t scuttle around like a headless fly, must figure out what to do... Hey, maybe try infiltrating the entire fortress array, to see how it’s set over the Golden Apple Stone Forest array."

Hilia arrived at a corner, carefully sensing, extending the Mage’s Hand, slowly merging into the array spread across the fortress.

"Be cautious, there might be an adept Array Master here, don’t let him notice." Rose reminded.

Hilia nodded seriously, becoming vigilant in her infiltration.

Soon, she noticed something amiss.

"Wait a minute, why does this array look so much like the school’s previous array?"

Hilia remembered the school’s array she had ’accidentally’ damaged before, a type called the [Starlight Seven Towers], comprehensive but with an obvious flaw, the seventh Starlight Node, Rest Starlight, the vulnerability of the whole array; once discovered, the array would be destroyed, just like it was at the school.

Excited, Hilia’s infiltration became bold.

Starlight Seven Towers, she knew it well.

Before long, Hilia grasped the entire array’s information.

After thorough screening, she found an abnormal point.

"There is a hidden entrance under the castle... Wait, it doesn’t look real; is it a decoy? It seems off too." Hilia furrowed her brows, puzzled.

Is it or isn’t it?

Rose chuckled lightly, "Can’t exactly call it a disguise; you could say you are both right and wrong. It’s an underground node for storing numerous items, also used occasionally for research, drawing attention if the Holy Court invades, while obscuring another deeply hidden node entrance."

Hilia’s eyes lit up, "Where is that entrance?"

"The node is underground, beneath the Golden Apple Stone Forest array, concealed by the array’s wave."

Pause, Rose said plainly, "Moreover, there is no entrance to this node."

"No entrance?" Hilia blinked, confused.

"No connection to above ground; the authority key you’re looking for is also hidden within that node. In regular scenarios, digging downward would hit the Golden Apple Stone Forest’s array first, being intercepted and unable to dig further down."

Hilia widened her eyes, "Such a node exists? A purely underground space unconnected to the outside?"

"Indeed."
