Volume One: Hell-Level Lord World — Chapter 150: Surveillance of Black Castle

"Kill them."

Watching the undead forces rush out from the gate, Lister led his troops forward without a moment's hesitation.

Although these undead were all skeleton soldiers, one could tell from their armor that they were elite troops.

Most importantly, they were shrouded in thick green mists.

The moment they surged out, they clashed head-on with Lister's forces.

This time, Lister suffered a heavy blow.

The combat capability of Lister's troops was certainly no less than that of these undead forces.

However, neither their defense nor their vitality had been significantly enhanced.

The green mist surrounding these undead troops was no mere decoration; it was potent, deadly poison gas.

Lister had been careless and failed to notice this. After the Great Fairies fought within the poison gas for a while, their vitality was directly reduced to zero.

Furthermore, any Great Fairy who fell in battle here would have their soul and corpse sucked away by that gate. The half-opened gate even widened slightly, and the undead forces inside attempted to squeeze out through this opportunity.

Realizing this at a glance, Lister understood that the gate relied on souls and corpses to open.

On one hand, he commanded the Holy Light Magma allocated to him to charge at the gate; on the other hand, he rapidly rotated his troops to attack the undead.

Whenever he saw his subordinates' health drop by half, he would pull them back and swap them out.

This ensured that his troops would not perish too rapidly.

Such a tactical style was immensely difficult for Lister.

Usually, he would simply charge straight through and slaughter everything; he had never needed to worry about the survival of his subordinates like this.

At that moment, Gu Chen also noticed that something was amiss over at Lister's position.

Normally, Lister should have already defeated the enemy's lich and been fighting his way back.

Why was there still no movement at all?

"Fire Spirit Crow, head over to Lister's side—"

Before Gu Chen could finish his sentence, a massive green gate appeared on the other side of the battlefield.

This sight gave Gu Chen a jolt of shock, and he instantly understood what was happening on Lister's end.

"Use Spark Bomb, and blow that gate to pieces for me."

Hearing the order, the Fire Spirit Crows flew over immediately.

Right at that moment, Lister had also discovered the traits of these undead and was commanding his troops in a rotational defense against the undead forces.

Seeing the Fire Spirit Crows fly over, Lister breathed a sigh of relief. Their arrival meant Gu Chen had already noticed the situation on this side.

All he needed to do next was coordinate with Gu Chen's plan.

Therefore, Lister took out his Brain-Worm Communicator, preparing to report the situation. But just as he pulled it out, the sky suddenly flashed.

Gu Chen and the others looked up at the sky simultaneously, discovering a gigantic, ice-blue eye hanging in the firmament.

This eye was staring intently at the green gate, as if pondering something.

Gu Chen was also startled by the eye in the sky, having a vague feeling that he had seen it somewhere before.

However, Gu Chen had no time to dwell on it. The moment the eye appeared, the Fire Spirit Crows had already charged in front of the green gate.

The command Gu Chen gave them was to blow up this gate.

Until receiving a new order, they did not care whether the situation before them had changed or not.

Under the gaze of the gigantic eye in the sky, the Fire Spirit Crows hurled their sparks directly into the green gate.

The sparks flew into the green gate for a brief moment before detonating on the spot.

More than three hundred Fire Spirit Crows threw over three thousand sparks that gathered together in a concentrated explosion, and the sheer force of the blast ripped the gate completely wide open.

Caught in the massive explosion, the green gate was instantly blasted into nothingness.

Only a huge crater was left in its place.

Even the troops fighting near the gate were caught in the shockwave.

A number of Great Fairies and Wood Sprites who failed to escape in time were crushed to death by the explosion's shockwave.

Perishing alongside them were those elite undead.

Witnessing this scene, Lister didn't care how many of his subordinates had fallen; he immediately charged forward with his Wild Wolves and Elven Blade Dancers to slaughter the remaining undead forces.

The gigantic eye in the sky spun around a few times, and upon confirming that the green gate had been completely obliterated, it slowly faded away.

As the giant eye vanished from the sky, Gu Chen suddenly realized something.

That eye—he seemed to have seen it inside the Black Castle when he first entered this Lord's World.

What was going on here?

Could it be that he had already attracted the attention of the Black Castle?

In truth, Gu Chen was overthinking it.

Such a trivial matter on Gu Chen's part was nowhere near enough to draw the attention of the Black Castle.

What had actually captured the Black Castle's gaze was the green gate opened by the lich.

Although the Nuremberg Empire was also an undead empire, there were thousands of undead empires, and not all undead factions maintained good relations.

Even the higher-ups within the Nuremberg Empire were riddled with internal conflicts, let alone relations between different empires.

Through various methods, the Nuremberg Empire had tricked their way into opening the gate to this Lord's World.

Their sole purpose was to monopolize this Lord's World for themselves.

Yet the green gate opened by the lich pointed toward a completely different undead empire.

To say nothing else, the green poison mist enveloping those undead soldiers was entirely inconsistent with the Nuremberg Empire's style.

While the Nuremberg Empire might tolerate elves living furtively within their territory, they would never allow another undead empire to open a passage leading into this Lord's World.

Therefore, the moment the green gate opened, the Black Castle dispatched an eye to investigate the situation at once.

If the gate were completely opened and the undead forces inside launched a large-scale invasion, then pardon them, a war called a Holy Crusade—but which was in reality a Scourge of the Undead—would begin.

However, Gu Chen and his companions knew nothing of this and simply blew the green gate out of existence.

Having lost its target, the giant eye paid no mind to Gu Chen's tiny garrison of cannon fodder.

It simply returned to report the situation.

As for Gu Chen's troops, possessing a grand total of only three heroes, they were far beneath the notice of such a colossal power.

Oblivious to all of this, Gu Chen was still pondering his own concerns.

What should he do if he encountered the Black Castle's forces ahead of schedule?

At that moment, Lister had already slain the undead radiating green poison gas and was leading his troops fighting his way back.

Over at the Vine Light, Gu Chen and Wanad had also resumed combat with the undead surrounding them.

Surmising that the main boss had already been slain, Gu Chen no longer worried about reserving backup troops; he unleashed every single soldier he had.

They were no longer on the defensive; the time for a counterattack had arrived.

Even Gu Chen himself leaped to the front lines, unleashing various spells upon the undead.

As spell after spell rained down into the ranks of the undead, Gu Chen felt his confidence surging back.
