"I should be asking you that! This is the Nether Realm. Just because you've washed away your Yang energy with Three-Life Water doesn't mean I can't recognize you as cultivators from the True Immortal World! Where did you come from? Return there immediately. The Nether Realm does not welcome the likes of you!" the black-robed middle-aged man said coldly.

"I see. We arrived here by accident. Are you perhaps a ghost envoy guarding this place?" Han Li asked, his heart stirred by the words, but he showed no sign of it on his face as he spoke with a smile.

"It seems you don't intend to retreat. In that case, die here! Form the formation... Ten Directions Heart Piercing!" The black-robed middle-aged man's expression turned cold as he waved his hand, drew the war spear from his back, and pointed it forward.

As soon as he finished speaking, the ghost soldiers behind him instantly split into two groups, forming two cone-shaped formations. The aura of the ghost soldiers within the formations connected together, forming a seamless whole, instantly transforming into a single entity.

The two cone-shaped formations transformed into two thick arrow shadows, shooting towards Han Li and Ti Hun. The speed was unbelievably fast, arriving before them in the blink of an eye, bringing with it a vast surge of ghostly energy and wind pressure. The space in front was almost shattered.

Caught off guard, Ti Hun staggered and was blown away.

Han Li, however, stood firm. While secretly marveling at the power of the ghost battle formation, his aura instantly surged wildly. A dazzling golden light burst forth from his hand, and a golden lightning sword appeared in his grasp.

With a series of hissing sword sounds, hundreds of golden sword energies shot out, instantly gathering in front of him into a rotating golden pillar of light, blocking the two thick black arrow shadows.

"Boom!"

The powerful force of the impact transformed into countless powerful streams of air, sweeping out in all directions.

The two battle formations came to a sudden halt, then were blasted backward. Although black light flashed wildly within the formations and ghostly energy surged, they did not collapse.

Han Li was also forced back two steps by the rebounding force before he stabilized his body.

Just then, the space behind him stirred, and a black spear shadow appeared out of nowhere, stabbing towards the back of his heart like a viper's tongue.

A flash of golden lightning, and another golden lightning sword appeared behind Han Li out of thin air, as if it had been waiting there all along, blocking the sudden spear shadow.

Another "Boom!"

Two unparalleled halos of black and gold suddenly appeared in this underground space, then erupted violently.

The black spear shadow was blasted back, and the figure of the black-robed middle-aged man appeared, a look of surprise on his face.

Han Li's body was also blasted away again, retreating backward. However, with a flick of his sleeve, a golden light shot out, transforming into a golden girl - Jin Tong.

"You and Ti Hun deal with those two battle formations!" Han Li said to Jin Tong.

Before he could finish speaking, his figure instantly leaped forward, rushing towards the black-robed middle-aged man.

The two golden lightning swords also shot towards the black-robed middle-aged man, arriving before him in the blink of an eye and growing a hundred times larger, like a giant golden pair of scissors, cutting down.

The black-robed middle-aged man's black war spear surged with black light, spinning rapidly, then thrusting out in fury, precisely striking the intersection of the two golden giant swords.

"Boom!" A crisp clang!

The two golden giant swords immediately stopped in mid-air, and the black-robed middle-aged man also used the force to shoot backward.

Seeing this, Han Li made a hand seal and guided the swords.

The two giant swords suddenly lit up, and two thick golden lightning bolts shot out from them. Because the two were extremely close, the black-robed middle-aged man didn't even have time to react before being struck.

An extremely dazzling golden light appeared out of thin air, enveloping the surrounding area for dozens of miles.

Within this space, all Yin winds and cold energy shattered and disappeared without a trace. Only intense golden arcs of electricity wandered and flickered, crackling.

But just then, a ball of black light appeared out of nowhere, and the surrounding golden arcs of electricity converged towards it like a whale swallowing water, being devoured by the black light.

The figure of the black-robed middle-aged man flashed into existence, completely clean, unharmed. The cuff of his right sleeve flickered with waves of black light, emitting a devouring force, which was the source of the black light.

In the blink of an eye, all the golden lightning disappeared into his sleeve.

Seeing this, Han Li frowned slightly.

The Doutian Divine Lightning was not only extremely destructive but also inherently pure Yang and extremely rigid, possessing a natural restraining effect on Yin ghost-attribute powers. Yet, it had been easily collected.

While thoughts flashed through his mind, his attack did not stop. He made a hand seal and pointed, and the two golden giant swords trembled. Hundreds of golden sword shadows emerged, covering the black-robed middle-aged man like clouds and mist.

The black-robed middle-aged man shook his war spear, and the spearhead trembled rapidly, transforming into countless black frosty stars, pointing towards those golden sword shadows.

Countless ear-piercing sounds of metal clashing resounded throughout the nearby space.

At this moment, Ti Hun and Jin Tong were also engaged in a fierce battle with the two groups of ghost soldiers.

Jin Tong transformed into a Gold Devouring Immortal form and was fighting one of the battle formations on equal terms.

However, her fighting spirit didn't seem high. She was only relying on her indestructible body to entangle this battle formation, preventing it from leaving, without attacking with all her strength.

On the other side, Ti Hun was flashing back and forth within the other battle formation. She looked very excited, grabbing with her hand in the void.

The sky suddenly darkened, and a small mountain-like black giant claw appeared out of nowhere, emitting a monstrous black energy, and grabbed down towards a cone-shaped battle formation. It was the Underworld Ghost Claw.

A monstrous force slammed down, instantly freezing the air within dozens of miles, turning it into steel. The entire battle formation also solidified.

But the next moment, the black light on the battle formation suddenly surged, tearing apart the surrounding giant force.

"Turn!" Within the battle formation, a ghost in the Taiyi realm shouted.

This person held a black banner, and as he waved it, black lights shot out from the banner, sinking into the black light around the battle formation.

The cone-shaped battle formation immediately stretched out, instantly transforming into a black demonic dragon form, strangling the falling black giant claw, holding it in mid-air, unable to fall.

Seeing this, Ti Hun didn't care. She even revealed a smile at the corner of her mouth and suddenly opened her mouth to spit.

A black glow shot out, swiftly rolling towards the tail end of the demonic dragon battle formation.

Due to the stretching of the battle formation, the protective black light covering the battle formation around it became thinner, and after being rolled by the black glow, it trembled a few times before it was torn apart.

The black glow flashed into the battle formation, wrapping around a few ghosts.

Seeing this, the Taiyi realm ghost roared, and the black banner in his hand danced wildly. The demonic dragon battle formation immediately rolled back, and sword energy-like crystal lights shot out, slashing towards the black glow.

Before those crystal lights could fly over, the black glow had already taken those few ghosts and shot back with a whoosh, swallowed by Ti Hun in one gulp.

Ti Hun once again showed a look of intoxication, and the black light on her body flickered, faintly becoming thicker.

"This is..." The black-robed middle-aged man who was fighting fiercely with Han Li in the distance changed his expression when he saw Ti Hun devouring ghosts.

Taking advantage of his distraction, Han Li transformed into a golden shadow and plunged into the sky-filled spear shadows, rushing towards the black-robed man.

At the same time, he quickly made hand seals, and a golden light flashed behind him. The Mantra Wheel appeared, spinning rapidly.

Countless golden ripples emerged, shrouding the black-robed middle-aged man.

But as soon as he moved, the black-robed middle-aged man immediately noticed and shot backward, his speed even faster than Han Li's.

The distance between the two quickly widened, and the golden ripples of the Mantra Wheel did not cover him.

The black-robed middle-aged man moved like lightning, instantly flying into the black abyss, and let out a sharp, piercing cry.

The two groups of ghost soldiers who were fighting with Ti Hun and Jin Tong immediately retreated, flying towards the black-robed middle-aged man.

"Master, help me catch some ghosts." Ti Hun looked anxious and immediately chased after them, shouting at the same time.

The two ghost battle formations were flying past Han Li, and Han Li heard this and made hand seals. The golden ripples beside him suddenly expanded several times, covering nearly a hundred ghosts.

The Mantra Wheel was now materialized, and its power had greatly increased. Covered by the golden ripples, those ghosts immediately stopped completely, frozen in place.

The other ghosts in the battle formation ignored their imprisoned companions and continued to fly towards the black-robed middle-aged man, reaching his side in the blink of an eye.

The black-robed middle-aged man took a deep look at Han Li and Ti Hun, and then plunged into the abyss and disappeared.

The two ghost battle formations also immediately followed, flying into the abyss.

"What's going on? Why did these ghosts suddenly retreat?" Jin Tong flew over, having transformed back into human form, and asked in confusion.

"I don't know." Han Li frowned and said.

In his brief exchange with the black-robed middle-aged man, he found that the opponent's strength was no less than his own. If the opponent was the guardian of this place, he shouldn't have retreated so easily.

Could there be other reasons?

"Master, quickly put away the wheel." Ti Hun flew over, ignoring the black-robed middle-aged man, drooling and shouting.

Han Li shook his head and smiled, making a hand seal to retract the Mantra Wheel.

The nearly hundred ghosts immediately resumed their movements and scattered, but a black spirit domain enveloped them, trapping all the ghosts, and they immediately fell into a swamp, unable to move.

Ti Hun opened her mouth and sucked, and the black spirit domain shrank rapidly, and the nearly hundred ghosts inside also shrank, slowly swallowed by the black spirit domain.

The black spirit domain finally transformed into a fist-sized pitch-black ball of light and flew into her mouth.

The black light on her body immediately flickered wildly, and waves of black spirit energy rippled out, spreading around, and only calmed down after a while.

The aura emanating from Ti Hun had actually increased significantly again, faintly approaching the peak of the early Da Luo stage.

"Forget it, although I don't know why that person suddenly retreated, it's good that he left. Let's go, let's go down and see what's in this abyss." Han Li said, taking the lead to fly down.

Ti Hun and Jin Tong hurriedly followed.

As a result, as soon as the three entered the abyss, they immediately felt as if they had entered a huge waterfall, wrapped in a force and rushing towards the darkness below.

This force was vast and boundless. Even though Han Li and the others were all Da Luo existences with powerful strength, they were helpless in the face of this force and were immediately swept away, plummeting downward.
