Zhou Huai had a premonition.

It wouldn't be long before a massive battle definitely broke out in Sakura Country.

Relying solely on Caesar's single Avatar wasn't enough.

He had to raise the strength of all Avatars as soon as possible.

After entering the Dungeon, Zhou Huai directly selected the Hell difficulty for them.

【Dungeon: Guard Athena (Hell Difficulty)】

【Mission Objective: Guard Athena's statue and fend off thirty waves of exotic beast attacks.】

The moment the scene shifted, a piercing alarm resounded throughout the entire space.

At the end of the white jade plaza, those four distinct regions seemed to be injected with berserk energy simultaneously.

This was the first time his Avatars had teamed up to participate in a Dungeon activity.

An endless army of exotic beasts surged from all directions like a tidal wave.

The earth trembled violently under the stampede of ten thousand beasts, as if it would shatter in the next second.

The sky was obscured by flying exotic beasts flapping their wings, casting endless shadows.

However, facing this apocalyptic scene, the five figures standing in front of Athena's statue did not show the slightest bit of emotion.

Xiang Yu took a step forward.

His stalwart body grew against the wind, instantly transforming into a ten-meter-tall demon god.

Pitch-black heavy armor covered his entire body, and his double pupils held an overbearing aura that looked down upon the world.

He was like an insurmountable mountain, single-handedly blocking the very front.

"Roar—!"

Overlord's Taunt activated.

Invisible sound waves swept in all directions with him at the center.

The aggro of all the exotic beasts was instantly locked on. Abandoning other targets with crimson eyes, they frantically charged toward that towering demon god.

Yasuo's figure followed closely behind.

He didn't have Xiang Yu's heaven-shaking might, but he was like a flash of lightning weaving through the storm.

His long blade was drawn, and thunder light suddenly flashed.

Armed with a single blade, he took the initiative to charge into the most turbulent beast horde.

Blade light flickered, and every swing stirred up a dazzling radiance of thunder.

The power of thunder frantically conducted through the dense group of beasts, and the splashing electric arcs, like the Grim Reaper's spiderweb, instantly charred a large swath of low-level exotic beasts.

In the rear, Da Yi slowly raised the unadorned longbow in his hand.

Without notching an arrow, he simply gazed calmly into the distance.

Starry Sky Vision activated.

In his field of vision, the entire battlefield transformed into a star map composed of countless energy nodes.

Those elite and boss-level exotic beasts mixed in the beast horde with exceptionally powerful auras were as eye-catching as torches in the dark night.

He released the bowstring.

An arrow condensed from starlight appeared out of thin air, tearing through the sky.

That arrow seemed to possess a life of its own, ignoring distance and obstacles as it precisely pierced the center of the eyebrows of a demon mage hiding behind the beast horde and chanting a spell.

Starlight Beacon attached.

The next moment, Da Yi's speed in drawing the bow reached the absolute limit.

Variable Arrow Rain activated.

Countless starlight arrows poured out like a meteor shower, with each arrow automatically tracking a powerful target he had marked.

At the back of the beast horde, gorgeous clusters of "fireworks" instantly burst open.

Meanwhile, Moria's figure quietly melted into the shadows of the ground.

Like a ghost, he shuttled through the corners of the battlefield.

Accompanied by his whisper, Shadow Assassins holding sharp blades crawled out from the shadows.

Like the most efficient assassins, they precisely reaped the lives of those high-threat units.

Whenever a Shadow Assassin completed a kill, the target's corpse would rapidly wither, turning into new Demonic Qi and giving birth to another even stronger assassin.

In the blink of an eye, a large-scale shadow legion had quietly formed in the enemy's heartland.

The rhythm of the entire battlefield was completely ignited by an unrestrained melody.

Sona's guitarist frantically plucked the strings, and the passionate solo tore through the sky.

The drummer was sweating profusely, and the heavy, powerful drumbeats struck everyone's heart like a war hammer.

The powerful rock music turned into visible sound waves, sweeping the entire audience.

The checkpoints that ordinary squads couldn't break through no matter how hard they tried were as easy as cutting melons and vegetables in front of this team.

Five hours later.

【Challenge Successful】

Four cold System characters hovered above the Dungeon space.

Controlling Zhuge Kongming, Zhou Huai stood together with Gao Yuan in the spectator space, silently watching all this.

With a thought, he brought up the backend experience points record.

A series of astronomical experience points made Zhou Huai nod in satisfaction.

Not bad.

Every Avatar's experience points had increased significantly.

This leveling speed was already on par with the beast horde in Donghai City back then.

Even surpassing it.

The only consumption was probably energy.

The essence of these experience points transformed out of thin air was the materialization of energy.

And the one providing energy for the Dungeon was precisely that magic crystal acting as the core array eye.

Zhou Huai roughly calculated.

The Hell difficulty "Guard Athena" Dungeon, from start to finish, consumed exactly one whole magic crystal for a complete clear, neither more nor less.

For a Dungeon, this energy consumption was terrifying.

You must know that usually a magic crystal was enough to maintain the normal operation of a medium-sized Dungeon for one to three months.

Yet his Dungeon exhausted the energy of the entire magic crystal in a single match.

The key to this lay in the experience points converted to Classer after exotic beasts were killed.

Although the Ximeng City Dungeon of Imperial Capital Academy was large in scale and simulated the grand scene of a beast horde laying siege to a city,

the students participating in the Dungeon actually played a negligible role in it.

The experience points they could obtain from the exotic beasts were pitifully small.

Most of the energy was spent on maintaining the operation of the Dungeon scenes.

Therefore, to maintain the operation of that level of Dungeon, the energy consumed was even much less than "Guard Athena".

Unless...

Unless a few perverts of Gandalf's level entered.

Standing on the city wall, crazily smashing Forbidden spells without regard for cost, absorbing massive amounts of experience points.

Only then would it cause a massive consumption of magic crystal energy.

Back in the days when Gandalf was still at Imperial Capital Academy, the magic crystal consumption of the Dungeon Tower was unprecedentedly huge.

The person in charge of the tower reported this to the principal of Imperial Capital Academy multiple times, but the principal suppressed it every time.

It's just that Zhou Huai himself didn't know about these inner details back then.

Now that it was his turn to call the shots and run a Dungeon himself,

did he personally experience how terrifying the operating cost of a high-yield Dungeon actually was.

Fortunately, the last thing he lacked right now was magic crystals.

There were still at least over 15,000 magic crystals snatched from the Zhou Family remaining.

It was enough to support him squandering for a long time.

He needed to use these magic crystals to pull together a team with formidable combat power in the shortest time possible.
