With Kane and their group joining the fortress defense, their advantage has grown increasingly significant.

Although the undead kept surging towards the walls, they could not survive long before being completely annihilated by Kane and their group around the walls.

At this moment, in front of the fortress, Kane stood at a defensive line stretching up a hundred meters, controlling the cannon muzzle above and clearing out the densely packed undead rushing forward.

Feeling the magic power within that still held above half.

Taking another look at the incessantly arriving undead.

Kane decided to go big.

Reaching over to his waist, a blue magic potion appeared in his hand and was promptly gulped down by Kane.

Feeling his magic power rapidly recovering within.

After waiting a brief moment.

A massive energy ball formed in Kane's hand, fully composed of the holy light attribute in his current state.

Then, with force, he hurled it into the sky.

The magic ball soared into the air.

Then burst open, with magic power spreading out, transforming into clusters of dark clouds. 𝓯𝙧𝙚𝒆𝙬𝙚𝒃𝙣𝙤𝒗𝓮𝓵.𝙘𝙤𝙢

"Such strong holy light energy!"

The bishop fighting on the fortress walls felt a gigantic wave of holy light energy descending from the sky.

With a turn of his holy light-transformed nail rod, he blasted a gold-class undead beside him into the air.

Then he turned and looked up to the sky.

Behold, without knowing when, the sky had become filled with dark clouds, making the already twilight sky appear even more dreary.

By this time, night had almost arrived.

But amidst the dark clouds, streaks of golden lightning were flickering in and out.

The dark clouds nearly enveloped the entire battlefield.

All those of great strength could feel the immense energy gathered within these clouds, with enormous surrounding magic power being absorbed within.

Something powerful was brewing.

Now Kane's entire body radiated golden light, his eyes and white robe with golden accents blazing with an intense glow.

Not a few priests and followers of the holy light even began to kneel in worship.

"It's a deity, God has finally come to save us!"

"The deity is casting celestial punishment upon these undead!"

The overlapping states of the Eye of the Gods and Divine Power caused Kane to exude a divine majesty.

Not only were humans awed, but many of the undead were also shaken.

The light emanating from Kane even pierced their souls.

A lich, having regained some magic power, grabbed its massive magic staff and aimed it at Kane's position.

An emerald ray shot instantly towards Kane's location.

Rui, below Kane, flapped his white wings and appeared instantly in front of Kane.

A large golden shield burst into radiant light, directly blocking the emerald ray.

An angel was personally protecting Kane, fending off the attack.

This was a visibly astounding sight for nearly everyone below.

The temple knights, clad in golden-accented armor, knelt sincerely in prayer.

Even their bishop closed the divine scripture in his hand, pressed it to his chest, and bowed his head.

Seeing he could no longer stop Kane.

Sitting in his chariot, the lich spoke to the Immortal Guard beside him, "Retreat, or it might be too late."

Speaking, he glanced up at the dark clouds overhead.

The clouds were densely crisscrossed with golden lightning, with the energy within reaching a critical mass and about to descend.

Upon hearing his words, the Immortal Guard loyally executed his command.

"Ahhhhh!"

The shrill cry of a banshee echoed across the battlefield once more.

This was the signal for the undead's retreat.

Countless undead, upon hearing the sound, immediately abandoned their adversaries and began a hasty withdrawal.

Some undead, with their own intelligence and will, seemed reluctant and still wished to fight.

But seeing the mindless masses of undead begin their retreat, they too were compelled to follow suit.

A metallic feather emerged from among a large heap of skeletons, instantly shredding the skeletons blocking its path into fragments.

Skulls and bone dust scattered across the ground indiscriminately.

The feather then landed next to Kafka, coalescing into the form of Raphael.

Kafka absorbed the soul from the skull he was holding, then discarded it aside.

At this moment, he truly appeared like a demon from hell.

"These undead seem to be in full retreat," Kafka remarked, observing the receding tide of undead.

Raphael looked towards Kane in the air not far off, seeing Kane extend his right hand toward the sky.

"But it seems these undead might not escape."

As his words trailed off, Kane lifted his arm, pointing his index finger, and waved it down a motion akin to a conductor's baton marking the final note.

An intense light illuminated the entire battlefield.

The lightning, long gathered amongst the clouds, began descending endlessly, each streak forged of golden holy light.

Imbued with a powerful retributive attribute, the lightning struck down with even greater might.

Rumble! Rumble!

Thunderous roars echoed throughout the battlefield.

The lightning struck with rapid speed and immense force, dealing extraordinary holy light damage to the undead.

A golden-class Frankenstein clad in emerald leather armor sensed a lightning bolt descending upon its head.
