Summoning the Gods: Start by creating the Eternal Night.

Below the crack, Yan Shisan led Jing Xinmo and the other two at breakneck speed, finally arriving at the underground altar.

In the center of the altar, beside the broken stone coffin, lay eight withered corpses, the surrounding blood aura so thick it was almost tangible.

"The key to the formation should be located beneath this altar."

Yan Shisan's gaze swept across the altar, finally landing on a groove in the center, which was covered with blood-red runes and was constantly emitting an evil aura.

"Let me investigate!" Mirror Heart Demon channeled his soul power and probed towards the groove.

"Be careful!" Yan Shisan warned.

Just as the Mirror Demon's soul power was about to touch the groove, the groove suddenly burst forth with a dazzling red light.

A powerful backlash came, and Mirror Heart Demon screamed as he was blasted away.

"This formation is backfiring!" Mirror Heart Demon clutched his chest, his face deathly pale.

Yan Shisan frowned slightly, drawing his longsword: "Get out of the way, I'll handle this!"

He thrust his sword into the groove, the gleaming blue tip colliding with the blood-red runes, producing a piercing buzz.

The runes flickered violently, and a powerful force emanated from the longsword, attempting to devour Yan Shisan's spiritual power.

"The Thirteen Deadly Swords - Death's End!"

A resolute glint flashed in Yan Shisan's eyes as he poured all his spiritual energy into his longsword.

The sword strike contained a suicidal aura, forcefully breaking through the rune's defense and piercing into the groove.

Just then, the people on the ground heard a deafening sword cry.

"It's Brother Thirteen!"

Yan Guiren was overjoyed. He knew that Yan Shisan must have found the core of the formation and started to make his move!

Once the formation is broken, he will no longer be in such a passive position.

Xue Wutian's expression changed slightly. He sensed a disturbance in the power of the underground formation and immediately felt something was wrong.

"Dare to tamper with the core of my formation? You're courting death!"

If the formation is broken, given his current cultivation level which has not fully recovered, he really won't be able to defeat Yan Guiren and the others.

Xue Wutian stopped entangled with Yan Guiren and flew towards the rift with a flick of his body.

"Want to leave? Not so easy!"

How could Yan Guiren let him succeed? With a swing of his halberd, the power of "Yan Fu Huan" erupted, completely blocking Xue Wutian's retreat.

"Get out of here!"

Xue Wutian roared, unleashing his full power of blood energy to forcefully shake off Yan Guiren, and sped off towards the crack.

"Snap!"

With a crisp sound, the crimson runes in the groove instantly dimmed, and the entire underground altar trembled violently.

The crimson barrier that enveloped Tianfeng City began to slowly crack, and the evil aura it emitted noticeably weakened.

"We succeeded!" Jingxinmo and the other two were overjoyed.

However, at that moment, a blood-red figure rushed down from the crack above; it was Xue Wutian who had returned.

"You little bastard, how dare you destroy the core of my formation!"

Upon seeing the scene on the altar, Xue Wutian's eyes blazed with murderous intent, and he struck Yan Shisan with a palm.

Yan Shisan sensed something was wrong and tried to dodge, but was locked in by a terrifying suction force and temporarily unable to move.

At this critical moment, a black streak of light shot out from the crack, and a halberd flashed like lightning, blocking Yan Shisan's path.

"Brother Guiren!" Yan Shisan exclaimed in surprise.

Yan Guiren held his halberd horizontally, forcefully blocking Xue Wutian's enraged attack. A loud clang rang out.

He was struck as if by a heavy blow, and a trickle of blood escaped from the corner of his mouth.

"Brother Guiren! Are you alright?" Yan Shisan broke free from the suction force and quickly stepped forward to ask.

Yan Guiren waved his hand, wiped the blood from the corner of his mouth, and looked at Xue Wutian, a smile appearing on his face:

"Old monster, is this your strongest move? It seems it's nothing special!"

Seeing the runes at the array's core dimming and hearing Yan Guiren's mockery, Xue Wutian's scarlet eyes surged with killing intent, and his blood energy suddenly boiled like bubbling oil.

"court death!"

With a roar, he formed hand seals and chanted obscure incantations.

"Black and gray fertilizer will volatilize and turn gray and black, which is taboo. The flowers will fly back and turn to ash. Gray fertilizer will volatilize and turn black and gray, which is taboo. The flying flowers will turn back to ash."

In an instant, a dense aura of blood surged from his body, coalescing into two blood-red figures identical to his own at his sides.

—It is one of his most treasured skills, "Blood Demon Clone"!

The two clones possessed auras that had reached the late stage of the Celestial Realm. Although not as powerful as the main body, they still carried a chilling killing intent.

They formed a triangle with Xue Wutian, surrounding Yan Guiren in the center.

"Today, I'll show you two arrogant brats what my power is!"

Xue Wutian grinned maliciously, and his main body and clone moved simultaneously.

Its blood-red claws tore through the sky, aiming straight for Yan Guiren's throat;

The clone on the left swung its blood fist, smashing it towards his heart with the force of a mountain collapsing;

The right-side clone transformed into a blood arrow, specifically targeting the lower body.

The three attacks sealed off all escape routes, and the killing intent almost materialized.

Yan Guiren brandished his halberd, his black armor flashing with spiritual light, and instead of retreating, he advanced: "Well done!"

He mastered the "Swallows Flying Together" technique of separating spear and staff, the halberd spinning like a wheel in his hand.

At times, it transformed into two afterimages, blocking the main body and the left-side clone respectively;

With a swift and agile footwork, he narrowly avoided the attack from the right-side clone, while simultaneously flicking the halberd's tail back, forcing the clone to retreat hastily.

"Clang! Clang! Clang!"

With three crisp sounds, Yan Guiren withstood three rounds of fierce attacks, but the fighting spirit in his eyes burned even brighter.

"Thirteenth Brother, the core of the formation has been completely destroyed!"

Yan Guiren roared and suddenly swept his halberd horizontally, forcing back Xue Wutian's true form and buying time for Yan Shisan.

Yan Shisan was already poised to strike. He immediately pointed his sword at the groove, channeling all his spiritual energy into the longsword without reservation.

"The Thirteen Deadly Swords - Final Move!"

The sword light, condensed like silk, carried the power to cleave through everything, and once again pierced into the already dimmed groove.

"Snap—!"

A crisp cracking sound rang out, and the blood-red runes in the groove shattered completely, turning into specks of blood light that dissipated.

The entire underground altar shook violently, as if it would collapse at any moment.

At the same time, the crimson barrier on the ground, like shattered glass, rapidly cracked.

Finally, with a loud "boom," it exploded completely, turning into a cloud of blood mist that dissipated into the air.

That suffocating, devouring force vanished without a trace in an instant.

As the barrier shattered, the omnipresent devouring power vanished instantly.

"The formation... is broken!" On the ground, Song Zongxiang and Shadow were overjoyed, their eyes gleaming with hope.

Leng Ming and Luo Tian's expressions changed drastically. With the formation broken, they lost their greatest support and were no longer able to suppress Song Zongxiang and Shadow.

Yan Guiren felt a lightness all over his body, and his spiritual energy flowed smoothly again, allowing him to unleash his full power!

He poured all his spiritual power into the halberd, and the halberd hummed, as if thousands of swallows were howling inside.

He leaped into the air, raising his halberd high above his head, unleashing the full power of a peak Celestial being.

"Swallows—return—to—their nests!"

The countless halberd shadows converged into a dazzling stream of light, carrying an indomitable momentum, and slammed fiercely towards Xue Wutian's main body.

Xue Wutian hastily gathered his blood energy to defend himself, but it was shattered by this attack containing boundless fighting spirit.

"puff--!"

He was struck as if by a heavy hammer; his body flew backward like a kite with a broken string, crashing heavily into the rock wall at the top of the altar.

It smashed a large hole in the rock wall and flew towards the ground.

"Boom!"

With a loud bang, Xue Wutian's body was blasted out of the ground and crashed heavily onto the open ground in the center of Tianfeng City, stirring up a cloud of dust.
