"This… how is this possible?" Seth couldn't help but look in disbelief at the scene that was happening in front of him.

Right after he and his army safely retreated to their second line of defense, the Undead Army attacked them in swarms.

However, despite their overwhelming numbers, the Undead were unable to push forward.

The reason for this was the great pillar of burning light that turned almost all Undead who passed through it into ashes.

Those who were able to pass through this barrier of light would continue to burn with Holy Flames, which left them disoriented.

These lucky or unlucky undead would then be blasted by Artillery and Tank Shells to oblivion, decimating them completely.

"This is a miracle done by the Saintess," Marion muttered as she looked at Shana, who was chanting while holding her staff.

Behind her, a hundred Wanderers who also possessed Holy Magic were channeling their power to her, amplifying her spell.

Behind this hundred Wanderers was a Mobile Generator powered by Empyrium.

This equipment continuously supplied the Wanderers and Shana with Aether, allowing them to keep the Grand Spell, Magnus Exorcism, active.

While Shana was doing her best to hold back the Undead Army, Thirteen was busy issuing orders from his Humvee.

"Do not waste your ammunition on the Undead behind the Pillars of Light," Thirteen ordered. "Only attack the ones that managed to get past it."

The young man then glanced at the Projection in front of him and saw the countless blinking dots that were about to merge with the Undead Army.

"You sure are impatient, Jalrog," Thirteen muttered as he gazed at the Centipede Army that appeared on the battlefield—this was not part of his agreement with the Centipede King. "You're even willing to sacrifice your minions for this farce."

The Centipede King wasn't supposed to appear in this battle.

They had agreed for Jalrog to only appear when the Alliance had pushed deeper into the center of the Rigel Continent, where the Earth Dragons resided.

There, they would tag team against the weakened Erasmus, allowing the Centipede King to deal him the killing blow.

'It seems that he's in a rush,' Thirteen thought. 'Well, it doesn't really matter. I also prepared for this kind of scenario.'

After tapping his communicator twice, the sound of whirring reverberated on the battlefield.

Dozens of Attack Helicopters flew over the Undead Army and went past them.

All of them were carrying some kind of container, which Thirteen planned to use at a later time.

However, since Jalrog's Centipede Army posed a serious threat to the alliance, the Supreme Commander of the Alliance no longer had the leeway to hold back.

The moment the Helicopters flew above the Centipede Army, the bottom of the containers opened, and the liquid stored within them was sprayed at the ground, drenching the Centipede Army.

"What's that?" Allen, who was right beside Seth, asked.

"I don't know," Seth replied. "We haven't been briefed about this."

This strategy was something Thirteen had come up with before the Commanders from the Ashford and Stallard Clan arrived, so it was only normal that they hadn't heard of it.

Just in case Jalrog broke their agreement and used his Centipede Army to attack him, he would unleash a chemical weapon that specifically worked against Insect Type monsters.

This was one of Thirteen's original concoctions, and he had asked his Grandpa, Arthur, to have this made when he returned to the Aldebaran Continent to pass over the Dragon Arm to Gerald.

Arthur understood that this weapon could benefit the Leventis Family better if it was kept a secret, so he made sure that only the people he trusted handled the process of its creation.

This Biological Weapon was called "No Bugs, No Life," and just like its namesake, it was incredibly effective against Insect Type Monsters.

Although Centipedes weren't really insects, but arthropods like spiders and scorpions, in Thirteen's point of view, they were one and the same.

They were all bugs that he could and would crush, so it didn't matter if they had two, four, six, eight, or a hundred legs.

The moment the "NBNL" was sprayed over the Centipede Army, they started to thrash like Earthworms sprinkled with salt.

Toxic fumes rose up in the air as the spray landed on the Centipedes and the ground, resulting in an orange mist that spread deep behind enemy lines.

The wind was blowing behind the Alliance's army's back, so they weren't in any danger of being affected by the fumes.

However, even from a distance, Jalrog could feel its senses tingle. With that alone, he understood that whatever weapon that the Wanderers were using, it was akin to poison to his army.

The Goblin Riders and the Orc Rider, who had also merged with the Centipede Army, weren't unscathed either.

They cried out in pain after inhaling the toxic fumes, for it made their eyes water and their throat burn.

Although it wasn't lethal to them, it was still a very painful experience, disorienting their forces.

The Wolves tripped over the Giant Centipedes that were thrashing on the ground, destroying their formation.

Jalrog knew that the only way to overcome this obstacle was to order his army to dig underground.

But just as he was about to give that order, a Roc descended from the sky.

Mounted on top of it was a Blaze Skunk, and sitting on top of that skunk was none other than Cristopher.

The Roc maneuvered itself to turn at the last second, allowing the Blaze Skunk's back to face the Centipede Army.

"Fire in the hole!" Cristopher shouted.

At that exact moment, a flamethrower erupted from the backside of the Blaze Skunk, igniting the centipedes and setting them ablaze.

Christopher's Roc glided across the Centipede Army, covering them with Hellish Flames.

Since the Undead Army refused to step forward, and the Centipede Army was right behind them, complete pandemonium took place.

The rest of the Jinns, who were supposed to reinforce their Vanguards, didn't dare to step into the blazing inferno in front of them.

Even though they were very far away from the blaze, the Wanderers still felt the heat of the flames, which was hot enough to make them sweat.

A minute later, Thirteen's order reached everyone's ears, snapping them awake from their trance.

"Retreat to the Third Line of Defense."

As soon as the order was given, the Army once again distanced themselves from the hellish battlefield that was burning so brightly, even from a distance.
