Chapter 939: Sweep the Plane

Lei En silently returned to the Star Destroyer, without alerting anyone.

The battle here was nearing its end; the Extreme Warriors and Holy Lance Knights swept the battlefield once, gradually flew back to the hangar, while Reslin dispatched his Mirror Image to finish the cleanup, ensuring no vampire was missed.

Prince Lu Si Fan Te's domain held over one hundred thousand vampires; after clearing them all, plus the baron's lands just destroyed by the "God's Staff," the spiritual pool's energy was nearly full.

This time, Lei En did not pour any energy into "My World."

There was nothing else elemental to upgrade either.

Titanium‑extreme body gold and the Energy Furnace are both Level 5; they must undergo the eighth Soul Transformation before upgrading again. Strength remains at Level 17, but once various amplifications are activated, it instantly reaches the Level 20 cap, so further upgrades are meaningless.

The current priority is to create Thundercast Celestial Soldiers—the more, the better.

Although curious about what "My World" could do, Lei En is in no hurry; he has decided to activate it only when energy overflows with nowhere to expend it.

Lei En teleported to the magical laboratory and quickly performed Olevi Creation Technique and brain‑splitting crystal.

Soon, one after another, Thundercast Celestial Soldiers emerged.

After creating a few, the battle in the prince's domain was completely over.

Lei En did not stop; he fashioned a Thundercast Celestial Soldier to look exactly like himself, clad in mithril light armor and a blood‑red cloak, becoming his duplicate, then applied Suppression Technique, making it appear flawless.

The duplicate teleported to the bridge, returning Reslin.

Ai Luoti Xi Ya saw Lei En's return, had no doubt, only curiosity about where Lei En had gone; clearly Lei En did not wish to answer, and she politely did not press.

She was still immersed in the Star Destroyer's overwhelming power.

In less than half an hour, the arrogant Prince Lu Si Fan Te and the vampires in his domain were wiped out clean.

That had been unimaginable before.

Ai Luoti Xi Ya exhaled lightly and asked softly, "Lei En, will you continue?"

"Of course."

Lei En nodded, "I said we must eliminate all demons in the Sighing Wilderness."

Pushing straight to Lu Si Fan Te's lands, the vampires killed totalled over two hundred thousand, yet that was only two‑thirds of all vampires in the Sighing Wilderness; another ten‑plus thousand vampires scattered across castles in the Black Thorn Forest awaited harvest.

Those are all energy!

However, it will take several hours to deplete the spiritual pool's energy by creating all the Thundercast Celestial Soldiers.

"We'll rest here."

Lei En's command rang through the Star Destroyer, "Brothers, rest half a day, then continue."

Extreme Warriors feel nothing; their powered armor lets them fight for days and nights without fatigue, but Holy Lance Knights cannot.

Lei En's duplicate steered the Star Destroyer into an Invisibility Field, then activated teleportation; thirty seconds later, the massive Star Destroyer roared, leapt into the void, and when it reappeared it was already over a minefield in the western hills.

The Star Destroyer landed, entering the mine's evil‑energy shield.

"Huh…"

Stepping out of the hangar, breathing clean air, the Holy Lance Knights let out a sigh.

After fighting all day, many Holy Lance Knights showed clear fatigue; prolonged exposure to the Abyss environment also risks their minds being corrupted by evil energy.

Ma Li Wu Si arrived at the bridge.

He glanced at the succubus, then at Lei En seated in the middle of the bridge, clearly aware this was only the original's duplicate, but pretended not to know and reported, "Sir, vampires in other domains may discover that Prince Lu Si Fan Te is dead and realize we are exterminating them. That will make those vampires defensive, even flee, increasing the difficulty of eliminating the enemy. Perhaps we should send the Extreme Warriors into battle immediately to reduce trouble."

Lei En knows his symbionts like the back of his hand.

Today's battle was far too unchallenging for the Extreme Warriors; despite killing many vampires, they were not satisfied.

They want to leave the Star Destroyer to eliminate a few vampire domains on their own.

That intention is good, and Ma Li Wu Si's reasoning is sound, but it hinders full use of energy.

"No need."

Lei En promptly rejected Ma Li Wu Si's proposal, "Our time is ample, the Sighing Wilderness isn't large; those vampires can't run far."

"I fear some vampires might escape to other planes…" Ma Li Wu Si said with genuine concern.

That remark reminded Lei En.

Only a handful of demons possess the ability to traverse the Abyssal Plane; they must first know the location of a plane passage and also have power beyond Legendary. The traversal process is very dangerous; at least reaching Legendary High‑rank makes it somewhat safer.

There are five vampire dukes in the Sighing Wilderness, so surely some vampires can escape to other planes.

We must not let them spread what happens in the Sighing Wilderness, lest it attract higher‑level demons, even the Abyssal Lord's attention.

Lei En looked at the succubus and asked, "Ai Luo Ya, how many plane passages are there in the Sighing Wilderness?"

"I know three," Ai Luoti Xi Ya replied.

"Tell me where they are."

Lei En produced a map of the Sighing Wilderness, had the succubus mark the three passage locations, then ordered, "Ma Li Wu Si, dispatch three squads of Extreme Warriors, each to guard one passage; no vampire may exit, nor may demons from other planes enter. Reslin will transport you to the sites."

"Yes, sir!"

Ma Li Wu Si shouted the order and departed.

The Sighing Wilderness's area equals three to four Empire provinces; Reslin performed several mass teleportations, sending the Extreme Warriors to their destinations.

Vampires guarded two of the passages and were instantly shattered by Bolt Guns.

With this arrangement complete, unless a caster is proficient in teleportation, demons below Saint Rank cannot even contemplate entering the Sighing Wilderness.

After Ma Li Wu Si left, Lei En had his duplicate scan the Star Destroyer's status. Every firing consumes source crystals and burdens the Titan Furnace and fire‑control rune arrays, requiring timely maintenance to keep the Star Destroyer combat‑ready.

This work is handled by Thundercast Celestial Soldiers.

Thundercast Celestial Soldiers are the Star Destroyer's maintenance mechanics; a Star Destroyer needs at least a hundred of them stationed to stay operational.

That is why Lei En needs to create so many Thundercast Celestial Soldiers.

After nearly ten hours, Lei En exhausted the spiritual pool's energy, creating over two hundred and fifty Thundercast Celestial Soldiers. Each forged its own weapons and armor, ready to join combat or assist in maintaining the Star Destroyer.

During this period, the Extreme Warriors indeed discovered vampire traces near the plane passages.

The vampires attempted to leave the Sighing Wilderness, but were all shot down by Bolt Guns.

Obviously, some vampires have already noticed.

Lei En gathered his legion onto the Star Destroyer, took off again, and teleported to a vampire duke's domain in the Black Thorn Forest, where he found the vampires on edge and many fleeing the duke's castle in a panic.

During the teleport, the Star Destroyer's Invisibility Field failed, leaving it hovering over the castle, and the vampires instantly let out terrified shrieks.

"Shoot it down for me!"

"Otherwise none of us will survive. My subjects, charge with me!"

A sharp voice rang from the castle—it was the duke of the domain. While shouting, he turned into a blood‑red silhouette, surged into the sky, and launched a surprise attack on the Star Destroyer, while hundreds of vampires turned into bats, forming a dense black cloud that swept toward the Star Destroyer.

More vampires took off from all corners of the domain, swarming the Star Destroyer from every direction.

The sheer number of bat swarms darkened the already dim sky even further.

AiLuotiXiYa saw the scene, her complexion flickered briefly, but she quickly regained composure, feeling regret for these evil foes.

"Courage is commendable."

Seated on the bridge, Lei En's avatar said lightly, and ordered the Star Destroyer to fire.

Boom— Boom— Boom……

Thirty‑two paired Electric Light Cannons fired simultaneously, spewing streams of lightning in rapid succession; two of the cannons, already fully charged, launched four dazzling electric shells.

Boom!

The massive electric shell slammed into the bat swarm surrounding the vampire duke, detonating instantly, its fierce light illuminating sky and earth.

All bats within a two‑hundred‑meter radius were cleared out.

The vampire duke was reduced to nothing but bone.

Vampires from other directions were struck head‑on; each lightning beam was equivalent to a five‑ring spell, as fast as real lightning, impossible to dodge, exploding on impact and easily slaying swaths of vampires.

After only a few seconds of barrage, ninety percent of the airborne vampires were dead, and none managed to get within a hundred meters of the Star Destroyer.

The surviving vampires, terrified to the brink, spun wildly and fled.

If they had known how terrifying the Star Destroyer was, they would never have followed the duke to their doom; before regret could even settle, the lightning beams arrived, and then they knew nothing else.

On the ground, the vampires who saw the scene were stunned.

They screamed and fled, but the Electric Light Cannon's barrel had already turned toward them, and bolts of lightning rained down, exploding amid the dense crowd.

Amid the booming, wave after wave of vampires were bombarded into ash.

The Soul Power Pool began to rise.

Lei En was already in the magical laboratory, racing against time to forge Thundercast Celestial Soldiers. Half a minute later, the Star Destroyer's main cannon finished charging, and a massive laser beam struck the duke's castle, the earth‑shaking explosion turning the castle into a huge crater and killing countless vampires.

That shot harvested over three thousand units of energy, and the Soul Power Pool surged by a third instantly.

Lei En let his avatar command the battle while he focused on creating Thundercast Celestial Soldiers.

Having learned in advance that strong foes might appear, the vampires were well prepared, some even fled the domain early, which made eliminating them a bit more troublesome.

The Star Destroyer had to fire more, and the Extreme Warriors and Holy Lance Knights pursued even farther.

But that was all.

Half an hour later, the duke's domain was completely destroyed; a few vampires escaped the disaster, and Lei En, without wasting time, piloted the Star Destroyer toward the next vampire domain.

Count's domain, Baron's domain, Duke's domain…

Vampire domains in the Black Thorn Forest were eliminated one after another; wherever the Star Destroyer arrived, a single main‑cannon blast razed the castle, then the vampires were exterminated.

After a full day, the Star Destroyer and the legion had wiped out fifteen domains.

Lei En devoted all harvested energy—over thirty‑thousand units—to forge Thundercast Celestial Soldiers, creating more than seven hundred of them. Including those previously made, the number of Thundercast Celestial Soldiers rose by a thousand in a single day, all at legendary Mid‑stage!

However, the vampires were already few left.

Almost every domain received the news; some vampires fled outright, some groups counter‑attacked, and upon discovering the Star Destroyer's horror, they immediately turned and fled.

This reduced the efficiency of vampire extermination; many fled into the Black Thorn Forest, forcing the Extreme Warriors and Holy Lance Knights to chase them, wasting much time. The Extreme Warriors stationed at the planar gateway also took the vampire onslaught, dying in batches.

Lei En switched to a scorched‑earth strategy, leveling every vampire domain to the ground, leaving them no shelter.

He then expanded the bombing radius, igniting the Black Thorn Forest.

The twisted forest was already small; the slight compression of the vampires' hiding space forced them out.

The vampires had to flee into a barren wilderness with no cover and no food source.

The Extreme Warriors and Holy Lance Knights spread out, carpet‑sweeping the wilderness for ten days, clearing the entire plane twice. Hundreds of thousands of vampires died outright; perhaps a few survived by luck, but it mattered little.

At this point, the Sighing Wilderness no longer saw any vampire silhouettes.

Lei En achieved his goal.

After ten days in the magical laboratory, having created fifteen hundred Thundercast Celestial Soldiers, Lei En finally emerged and swapped out his avatar.

"AiLuoYa, what are you looking at?"

Lei En asked while admiring the succubus's silhouette; she wore a dark‑red leather coat, her seductive curves on full display. Since the succubus entered the Star Destroyer, she had spent most of her time on the bridge, even when there was no combat, staring blankly out the window.

AiLuotiXiYa turned to Lei En, her flawless face breaking into a bewitching smile.

"I'm looking at this plane."

She whispered, "Lei En, you already control this plane; it's something countless demons have only ever dreamed of attaining."

"It's just a small plane," Lei En shook his head, saying with a playful grin, "If I were a demon, the Sighing Wilderness wouldn't make me an Abyssal Lord. Moreover, the Sighing Wilderness is too barren; those demon lords disdain it, otherwise vampires wouldn't be the ones to occupy it."

"Indeed…" AiLuotiXiYa nodded.

Lei En added, "Once I finish extracting the source crystal, I'll abandon the Sighing Wilderness, leaving at most a secret base here as a teleportation hub."

"Are you leaving the Abyss?"

The succubus's tone unintentionally rose a few notes, her eyes tinged with reluctance and apprehension.

Lei En read her thoughts and smiled, "I'm human; the Prime Material Plane is my home, so I'll certainly leave the Abyss. AiLuoYa, will you come with me?"
