Summoning the Gods: Start by creating the Eternal Night.

After Yi Shangqi was dealt with, only bloodshed and devastation remained on Black Wind Ridge.

Li Wujiu turned around and bowed deeply to Di Shitian.

His back was bent extremely low, his voice hoarse yet filled with an unprecedented determination:

"From this day forward, I, Li Wujiu... am willing to lead the remaining forces of the City of Sin to submit to the Underworld and submit to its commands!"

Having survived this life-or-death ordeal, he finally saw the situation clearly.

The Ghost King Sect's covetousness and Yi Shangtai's betrayal made him realize that in this chaotic world where the world is about to change,

It is simply impossible to establish oneself on one's own.

The underworld has powerful beings like Indra, who are terrestrial deities.

Perhaps this is the only way to protect Sin City and preserve oneself.

Indra looked at him, a hint of approval flashing in his eyes.

Those who understand the times are wise, and Li Wujiu's ability to make decisions in dire circumstances shows that he is not foolish.

He nodded, his tone calm yet carrying an undeniable authority.

"good,"

"From this day forward, Sin City is incorporated into the Underworld."

"You will continue to serve as the Lord of Sin City, and as a covert force of my Underworld, try your best not to expose your relationship with us."

"As for your position in the Underworld, the King of the Underworld will arrange it in the future."

Li Wujiu's heart skipped a beat.

The words "Lord of the Underworld" made him even more certain that the depths of the Underworld far exceeded his imagination.

He quickly bowed and greeted them respectfully:

"Your subordinate obeys! Thank you, Lord Eastern Ghost Emperor!"

He had not previously joined the Underworld, so he addressed Indra as Fellow Daoist.

Now that he has joined the Underworld, he must assume the position of Emperor Shitian in the Underworld.

"Now that you have entered my underworld, you are one of my own from now on."

"Although the rules of the Underworld are strict, the most important rule is loyalty to the Underworld."

"If I ever discover that you have any disloyal thoughts, I will tear your soul out."

"Send me to the eighteenth level of hell in my underworld, so I'll show you what it means to wish for death but not to live."

Di Shitian's icy gaze was fixed on Li Wujiu.

Li Wujiu was immediately frightened by Di Shitian's gaze, and cold sweat involuntarily poured out.

"By the will of Heaven, I, Li Wujiu, submit to the Underworld today."

From that day forward, he would be utterly loyal to the Underworld, and would never waver in his loyalty.

I, Li Wujiu, am struck by lightning and will never be reincarnated.

Li Wujiu immediately made a vow to Heaven.

A master of the terrestrial immortal realm, once he makes a vow to the Heavenly Dao...

If anyone dares to break this oath in the future, they will be punished according to the will of Heaven.

"boom!"

Just as Li Wujiu finished making his oath, a thunderous sound seemed to resound in the sky, signifying that the oath had been fulfilled.

Indra smiled quietly:

"Get up. Let's go back to Sin City to handle the aftermath."

"Yes."

Li Wujiu stood up in response, but a hint of worry flashed across his brows.

"But... I wonder what the situation is like in Sin City right now?"

"Will the Ghost King Sect launch a sneak attack while I'm away from the city?"

Although he ordered the city's commander to strengthen defenses before leaving the city, he was already certain that Yi Shangqi had betrayed him.

It's hard to guarantee that Yi Shangtai won't join forces with the Ghost King Sect to take advantage of my absence and launch an attack.

Indra remained calm:

"Don't worry. I sent people to Sin City before I came to your aid."

"With them here, the situation can be stabilized."

Upon hearing this, Li Wujiu felt a sense of relief and admired Di Shitian even more.

"As you've considered, sir! Let's head back to Sin City immediately!"

"Yes." Indra nodded.

Without further delay, the two transformed into streaks of light and sped off towards Sin City.

……

Meanwhile, Sin City is engulfed in a chaotic battle.

Inside the city lord's mansion, shouts of battle, the clash of weapons, and the screams of the dying mingled together, creating a bloody tragedy.

On the ground, corpses were piled up in layers.

There were guards dressed in the uniforms of the city lord's mansion.

There were also Ghost King Sect cultivators dressed in black.

Blood stained the bluestone slabs, meandering along the cracks and emitting a pungent, fishy smell.

Not long ago, several of Yi Shangqi's trusted confidants left in the city...

Seeing that City Lord Li Wujiu had left, he secretly opened a gap in the city's protective array.

They released the Ghost King Sect cultivators who had been lying in wait outside the city into the city.

Leading the group were Elder "Ghost Three" and Elder "Ghost Four" of the Ghost King Sect.

Ghost Three's cultivation level reached the late stage of the Celestial Realm, while Ghost Four's was at the middle stage.

The two led a dozen or so elders from the Nirvana Realm and hundreds of elders and disciples from the outer sect.

They pounced on the city lord's mansion like hungry wolves, intending to take Sin City in one fell swoop while Li Wujiu and the second and third elders were away.

Qin Lie, the city's commander at the late-stage Celestial Realm, is currently battling the Third Elder of the Ghost King Sect.

He brandished his longsword, the blade flashing with power, each strike carrying the resolute determination to protect.

However, because he was distracted by the situation around him, he gradually fell into a disadvantageous position.

"Clang!"

As the longsword collided with the Third Elder's ghostly claws, the city guard commander felt a numbness in his arm, and the longsword almost slipped from his grasp.

He groaned and used the momentum to retreat, his chest already burned by the ghostly energy, leaving a dark claw mark.

"Hahaha! With Li Wujiu gone, this City of Sin is now in the hands of my Ghost King Sect!"

Elder Ghost Three grinned maliciously, pressing closer step by step, the black aura on his ghost claws growing increasingly dense.

The fourth elder, Mo Cang, was an old man with white hair, whose cultivation was only at the early stage of the Celestial Realm.

At this moment, he was being entangled by the Fourth Elder of the Ghost King Sect.

Despite his best efforts, he could only barely hold on, and he had several wounds on his body, his breathing gradually becoming disordered.

"Commander Qin! I can't hold on much longer!"

The fourth attendant, Mo Cang, shouted breathlessly, his eyes filled with anxiety.

Qin Lie glanced at the other battlefields out of the corner of his eye.

Several Nirvana Realm elders from the City Lord's Mansion are currently engaged in a fierce battle with an inner sect elder from the Ghost King Sect.

They were already outnumbered, and then caught off guard...

At this moment, the casualties were already heavy, and only three people remained to hold on, and they could be wiped out at any time.

"Hold on! You must hold on! The city lord will be back soon!"

Qin Lie quickly shouted sternly, trying to calm everyone down.

Seeing this, Elder Gui San's eyes flashed with smugness, and his attacks grew increasingly fierce.

"Hahaha, don't even think about it, Li Wujiu isn't coming back!"

"Give up the resistance! Surrender to my Ghost King Sect, and perhaps we'll spare your lives!"

"Hmph! Don't even think about it! I'll take you down with me even if I die in battle."

Qin Lie channeled all his spiritual power and attacked Gui San once more.

On the battlefield of Nirvana Realm

A Nirvana-stage early-stage elder of the City Lord's Mansion was severely injured by a Nirvana-stage mid-stage elder of the Ghost King Sect.

He was sent flying backward, spitting out blood, and crashed heavily into the pillars, the sound of bones shattering clearly audible.

He struggled to lift his head, looking at the enemy closing in, his eyes filled with despair.

"It's over..."

He muttered to himself, about to unleash the spiritual power within his body and perish together with his opponent.

Just at this critical moment

A short sword, with a whooshing sound, went straight for the Ghost King Sect's mid-stage Nirvana Elder who was about to kill him.

"Pfft!"

The elder was caught off guard and struck the back of the head by the short sword.

"Bang!"

With a muffled thud, his head exploded like a shattered watermelon.

Red and white splattered all over the ground, and the corpse fell straight down.

"A vengeful ghost snatches away souls, and the harbinger of death demands a vengeance!"

A cold male and female voice rang out, like a chilling wind sweeping through the depths of hell.

Then, two figures darted into the courtyard of the city lord's mansion like ghosts.

A man dressed in black, holding a soul lock, exuding a chilling aura, was none other than Black Impermanence, Chang Haoling;

The other person, dressed in white, holding a mourning staff, with eyes as cold as frost, was none other than Bai Wuchang, Chang Xuanling.

The sudden turn of events stunned both sides in the midst of the chaotic battle.

The other Nirvana Realm elders of the Ghost King Sect all turned to look at Black and White Impermanence.

Sensing that the cultivation aura emanating from the two far surpassed that of themselves, they both frowned.

"Who are you? Why are you interfering in the affairs of my Ghost King Sect?"

An elder at the Nirvana Realm mustered his courage and asked, his tone wary.

The Black and White Impermanence exchanged a glance, a cold glint flashing in their eyes.

"Hehehe, we are the Black and White Impermanence of the Underworld!"

"Your duty is to collect souls and claim lives; today I'll subdue you horde of evil spirits!"

Before the words were even finished, the soul-snatching chain in Black Impermanence's hand seemed to come alive.

With a "whoosh," it transformed into a black shadow and entangled the four Nirvana Realm elders.

Black energy swirled around the chains, carrying a strange power that could lock away souls and spirits.

Bai Wuchang also moved swiftly, blocking the other four Nirvana Realm elders, his mourning staff wielded with impenetrable force.

With a few crisp "clangs," the opponent's attacks were completely blocked.

The attack was so fierce that it forced the four of them to retreat repeatedly.

The situation on the Nirvana Realm battlefield was instantly reversed due to the arrival of the Black and White Impermanence.
