Lin Feng pursued closely, passing through the clouds, and thrust the Wildfire Spear forward once more.
But Hel launched a desperate counterattack during his fall—【Soul Scream】! The silent soul impact locked onto Lin Feng, striking deep into his mind, and the accompanying fear effect was enough to instantly collapse an ordinary powerhouse.
However, the moment the soul impact struck Lin Feng, the clarity in his eyes did not waver in the slightest, and his 85% negative resistance once again forcibly exempted him from fear.
Lin Feng accelerated forward, using the momentum of the Wildfire Spear to thrust it out, the tip tearing through the air, aiming straight for Hel's chest.
Hel did not take the hit head-on. The Curtain of the Dead suddenly unfolded, and a black curtain with a radius of eighty meters appeared out of thin air, enveloping the two of them at the same time.
Inside the curtain, all of Lin Feng's damage was significantly reduced.
At the same time, Hel activated Elemental Unity, his entire body glowing with golden light, and his shield gained a terrifying damage reduction effect equivalent to his entire body's defense.
The Wildfire Spear pierced the double damage reduction layer, its tip sinking into the pale golden light membrane. The spell deflection was triggered again, and the spear was violently slid away.
The two engaged in close combat within the black curtain. During the gaps in his parries, Hel continuously unleashed Shadow Arrows, firing at a terrifying rate of three arrows per second, raining down on Lin Feng.
Lin Feng unleashed a flurry of spear strikes, deflecting the arrows aimed at him. His leg armor glowed with a shadowy light, triggering the Shadow Step ability, which boosted his evasion rate. Two shadow arrows grazed his shoulder armor and side, missing their mark.
He spun around, his Wildfire Spear sweeping across, the blade drawing a golden arc in the darkness of the curtain before striking the side of the Hel Shield, causing its value to drop further.
Hel used the momentum to retreat, activating Bone Regeneration. Dark gray healing light surged from its body, and the overflowing healing triggered the set effect, instantly restoring the shattered shield value to full.
Lin Feng narrowed his eyes; it was the same old cycle again.
After six days of practice, he had become so familiar with Hel's "injury recovery shield" rhythm that it was ingrained in his bones.
If the regeneration of bones is not suppressed, this tortoise shell will never be broken through.
He took a deep breath, preparing to press forward again, but Hel suddenly took the initiative to create distance.
Shadow Step was activated again, but this time it wasn't used to dodge; instead, it teleported backward a full hundred meters.
The black mist left a long trail in the curtain, and Hel reformed his form a hundred meters away.
It raised the Annihilation Bone Staff, and the crystal at the top of the staff shone with an unprecedentedly dazzling purple light, a sign that the forbidden spell "Annihilation Light" was gathering power.
Lin Feng stared at the purple orb of light, his spear tip slightly lowered, his muscles tense, preparing to block and withstand the attack the moment Hel released it.
Then, Hel suddenly stopped.
It wasn't interrupted by a skill; it stopped on its own.
The purple orb at the top of the staff hovered in mid-air, spun a few more times, and then vanished silently.
The purple light faded from the crystal, as if a flame had been extinguished from within.
Hel maintained its stance with the cane raised, but its gaze had already shifted away from Lin Feng.
Its skull tilted slightly, and the soul fire in its eye sockets flickered violently—a fluctuation that Lin Feng had never seen before in it.
It wasn't fear, it was extreme anger.
The next second, Hel put down the bone staff.
It raised its skeletal left hand and issued a silent command to all undead units.
This command was transmitted throughout the battlefield via the passive effect of "Domination of the Dead," causing the high-ranking death knight, who was engaged in aerial combat with a human powerhouse, to stop his bone sword.
The Bone Dragon King, who was fighting Suleiman and Edmund at a distance of 600 meters, folded its wings, and the million-strong skeleton army that was attacking the city on the ground stopped advancing at the same time.
Then, the troops withdrew.
The Lich King Sazar's bone spear was only half-formed, and the dark light at the tip of the spear was still flickering on the top of the staff.
It turned to look at Hel, its soul fire revealing obvious confusion, but Hel did not explain, only repeating the command again.
Sazar put away his bone spear, paused with his bone staff, and began to retreat.
The remaining Death Lords, Bone Dragon Kings, and Liches followed closely behind, turning in unison in the air and retreating towards the undead camp, stepping on the black mist.
On the ground, the skeletons charging the city walls turned around simultaneously. They did not retreat in disarray, but rather with an orderly retreat. The skeletons retreated first, the undead warriors covered the rear, and the death knights provided cover on both flanks.
The bone snake detached from the city wall, its thick spine pulled out from the cracks in the bricks, bringing down a large amount of rubble, before slowly retracting back to the ground and retreating back into the sea of bones along the same path.
The siege tower of bones stopped moving, and the undead archers at the top put away their bone bows and retreated down the bone ladder inside the tower.
The bone rollers at the base of the tower began to rotate in the opposite direction, slowly dragging the siege tower away from the outside of the city wall.
The undead army outside the four city walls was retreating simultaneously—not pausing its attack, not adjusting its deployment, but a full-scale retreat.
Lin Feng hovered a thousand meters in the air, the Wildfire Spear hanging at his side. He stared at the back of Hel Shadow, whose figure, stepping on black mist, was flying towards the undead camp at a slow speed, his posture still majestic.
He didn't chase after her. He and Hel fought for six days and had figured out each other's skill cooldowns, movement distances, and output rhythms very well.
He could chase, but there would be no point in chasing. Without the concentrated fire support of friendly forces in the air, it would be impossible to kill a level 49 Undead King alone.
Hel knew this, which is why it dared to turn around so calmly.
Lin Feng stopped in his tracks, his gaze passing over Hel and looking towards the distant horizon.
There, the once endless sea of grayish-white bones was receding into the distance at a speed visible to the naked eye.
A thousand meters below, the city of White Tower fell into a deathly silence.
The defenders on the city wall saw the skeleton turn around, saw the bone snake fall off, and saw the bone siege tower move in the opposite direction.
They saw the undead army retreating from outside the city walls like a receding tide, but they couldn't believe their eyes.
No one cheered, no one laid down their weapons. Six consecutive days of attacks had put them on high alert and into a conditioned reflex.
In everyone's subconscious, the retreat of the dead is often just the prelude to the next, more brutal charge.
But this time, it seems to be really different.
The skeleton retreated 300 meters away, then 800 meters away, then 1200 meters away. The remains of the bone serpent disappeared into the depths of the sea of bones, and the outline of the bone siege tower grew smaller and smaller until it became a blurry gray-white shadow on the horizon.
The city wall remained eerily quiet, with only the mournful sound of the wind whistling through the crenellations.
"They... withdrew?"
The voice was soft, trembling with uncertainty. It was the young archer who was calling out. He was still standing by the crenellation, his bowstring still fully drawn, the arrowhead pointed firmly towards the outside of the city.
His voice was exceptionally clear on the quiet city wall, so clear that everyone around could hear it.
"They've left." This time, the voice carried more confidence.
He was a veteran garrison infantryman whose face was covered in blood.
He slowly lowered his shield, straightened his body, and stared with his bloodshot eyes at the receding sea of bones outside the city.
"The undead have retreated!!"
