Chapter 666: Chapter 551: The Might of the Undead Sea and the Sun Flame Cannon!_2

This move was undoubtedly very effective. Millions of undead that lingered in the valley all sank into the earth, followed by the artillerymen switching to special ammunition. With a barrage of fire, a scorching sea of flames began to spread beneath the valley floor.

“It seems these dead spirits are not such a big deal after all. If this is all they’re capable of, it doesn’t matter how many more come!”

Alade looked at the skeletons that had fallen into the earth, shattered into pieces, some trying to struggle to their feet only to be buried again, and his anxiety over the cross-dimensional war eased significantly.

Weak, they were simply too weak. Just cannons, muskets, airships, and a few traps were enough to crush all these invading undead to pieces.

Wizards who thought like Alade were not few in number. Some even began to comment and discuss, talking about which of the undead emerging from the Space-Time Gate were strong and which were weak.

Harrov and others did not let down their guard, because so far not a single legendary-level dead spirit had appeared before them. This likely meant that all the undead seen so far were merely fodder for probing their defenses, which is why he had always refrained from having everyone use some of the more powerful weapons.

In fact, just as Harrov had thought, as time passed, Alade and the others who had initially appeared disdainful were now starting to break out in a cold sweat.

The battle went on straight from the morning until late at night. An endless number of undead poured out from the Space-Time Gate. Many wizards keenly realized that since they had sunk the entire valley, no ground undead had emerged from the Space-Time Gate anymore. Instead, more flying dead spirits came forth.

And they were not as foolish as imagined, constantly changing their attack strategies. Instead of moving in clusters, many dispersed, and some Screaming Demons even attempted to approach them by flying at low altitude.

Just relying on the Thunder Net for blockage was no longer sufficient to stop all targets. The roaring of the machine guns never ceased, relying on crossfire to eliminate those that slipped through.

This meant that the commanders of the undead army seemed to have some way to be aware of what was happening here and made tactical adjustments accordingly. Moreover, they had more troops than expected, so they did not care about such losses and remained very composed.

“Have you noticed? Some of the undead do not join the battle after flying out of the Space-Time Gate but instead immediately return through it,” Harrov murmured thoughtfully.

“Scouting sentries?” Sanchez immediately responded.

However, even with this knowledge, it was of no use. They could not possibly kill every undead that passed through the Space-Time Gate, naturally unable to stop them from returning.

“Just how many of them are there?” Alade couldn’t help asking out loud.

The council had spent more than a year stockpiling ammunition, which was now nearly one-third depleted. After running for dozens of hours, the Thunder Stones were also nearly exhausted. Yet, the number of undead emerging from the other side of the Space-Time Gate did not appear to diminish at all.

Although with the Thunder Net diffused across the sky and the wizards’ Fluorescent Light Technique, the darkness did not weaken their combat effectiveness. But after fighting for dozens of hours in succession, many were feeling mentally exhausted.

Even warriors with strong willpower needed rest. Could it be that the enemy planned to wear them down over ten days to half a month until their ammunition and stamina were completely depleted?

No one could answer that question. Harrov had already implemented a shift system, with even the official wizards joining the fight, substituting for some of the cannons. Even the Thunder Net had been temporarily shut down.

Magic power could be recovered, but the production and replenishment of ammunition and energy were not issues that could be resolved in a short period.

“Should we use that?” Aurora asked, referring, of course, to nuclear weapons.

To deal with such a vast number of enemies, a single Sky Vaulting was obviously the quickest solution!

It could even be dropped directly on the other side of the Space-Time Gate. Given the number of invading undead, it should be able to annihilate millions of dead spirits in one go, also giving them some respite and time to recuperate.

Harrov hesitated somewhat,

as according to previous plans, the council’s nuclear reserves were meant to deal with legendary creatures and the Lord of the Undead, using them on mere fodder seemed somewhat wasteful.

But continuing to fight like this was not a solution, it seemed they had to use the nuclear reserves ahead of time!

Harrov quickly made up his mind.

“What is that?” Sanchez suddenly pointed at the surging Space-Time Gate ahead, speaking in shock.

Harrov and the others paused for a moment and looked in the direction Sanchez was pointing.

A fist-sized dark sphere was drifting out from the Space-Time Gate several kilometers away, and without the aid of the far-sight magic, no one would have noticed it.

Was it some kind of offensive spell? Or a peculiar undead creature?

Harrov had no idea, but he wasn’t about to let it linger, either. With a wave of his hand, a rune-light flickering electromagnetic cannon materialized in front of him, racing at over thirty times the speed of sound and promptly hitting the chaotic sphere dead-on, instantly shattering it!

However, Harrov’s expression turned extremely ugly because, as the sphere burst apart, an invisible force swept through the valley immediately.

The method to activate this spell was actually to detonate it!

The enemy had used their actions to complete the final step of the spell!

In the sky, the countless undead that were knocked down by machine guns and shattered by beams of light hadn’t even fallen into the fierce inferno below before bursting open, billows of dark green toxic fog erupting from the chunks of remnants, swiftly covering the entire airspace.

This was the legendary undead magic—High-level Corpse Explosion Technique!

“We must not touch this fog…” Vittorio watched the drifting fog approach, feeling an ominous sense of dread.

Even for a legendary wizard like him, it would be unbearable to get contaminated!

Seeing the toxic fog spreading toward them, Vittorio and Harrov immediately joined forces with a dozen elemental grand wizards nearby, summoning a hurricane in an attempt to blow the poisonous wind back into the Space-Time Gate, since the army of the kingdom surrounded the valley and there were airships above as well.

However, despite a dozen grand wizards joining forces with Harrov and the legendary wizard Vittorio, they only just managed to keep the toxic fog within the confines of the valley.

Under the gale’s onslaught, the sharp-eyed Sanchez realized that this was not fog at all, but an endless sea of soul specters!

Expression after expression of fierce and agonized faces emerged within the swirling mist.

In other words, they were now facing millions of souls of the dead from this battlefield!

Realizing this, a chill ran down the spines of the wizards present.

These resentful spirits, who had suffered tragic deaths and were enslaved after death, were unleashing their greatest malice, constantly assaulting the incoming storm, desperately trying to break through the blockade and consume all the living on the outside.

Then, the roaring of bone dragons echoed within the dark green fog.

Under the cover of the Dead Sea, the real offensive was now officially underway!

More Screaming Demons than before surged out from the Space-Time Gate, accompanied by dozens of bone dragons, hordes of Undead Gryphons, and even higher-order banshees and corpse wizards—they were the core force of the undead legion, beyond the level of cannon fodder.

At this moment, Harrov actually sighed in relief, for that which they dreaded most and feared was the uncertainty of the enemy’s depth just moments ago; now that the enemy had deployed their elite troops, they could finally let loose.

“Let these skeletal frameworks taste the ultimate masterpiece of the Wizard!” Harrov declared without hesitation.

The Sun Flame Cannon, which had stood immobile in the center of their formation, now pivoted its muzzle towards the direction of the Space-Time Gate. As a 500-kilometer yield high-purity uranium stone was loaded, a blindingly destructive light immediately emerged on the battlefield…
