Han Li's eyes flickered, and he chanted rapidly, then waved his sleeve with one hand.

Three green giant swords immediately shot out like lightning, forming a triangular formation and slashing toward the blue mermaid. Golden lightning intertwined around the swords, radiating a vast golden light.

Faced with the three people's swift and coordinated attack, the blue mermaid's expression became even more ferocious. It waved the blue staff in its hand violently, and with a series of hissing sounds, countless blue staff shadows vaguely emerged around it, condensing into a thick layer of staff shadow light screen that collided with the attacks of the three.

Whether Han Li and the other two had truly exerted their full strength was unknown, but their offensive was like a torrential storm, wave after wave. Even ordinary early-stage Taiyi realm cultivators would probably be unable to withstand it.

A series of earth-shattering explosions, "Rumble!", rang out!

Although those blue staff shadows seemed indestructible, they were constantly being shattered. The staff shadow light screen rapidly thinned and soon completely collapsed.

The blue mermaid's staff shattered in its hand, but immediately after, a blue light flashed in its other hand, and a similarly ancient-looking blue fishing rod appeared, with a thin blue fishing line attached to it.

The mermaid flicked the fishing rod, and the fishing line immediately danced, moving with extreme speed around its body.

Wherever the fishing line passed, waves of blue light surged from the void, and the space twisted, forming rapidly rotating blue vortexes.

The three Green Bamboo Bee Cloud Swords slashed onto those blue vortexes, creating a large swath of golden lightning that swept down, but upon contact with the blue vortexes, they disappeared without a trace as if they had sunk into the ocean.

The vortexes only trembled slightly before immediately returning to their original state.

Han Li felt as if the three giant swords were striking into a vast and boundless sea, their contained power of creation being swallowed by the endless seawater and then completely neutralized.

Almost at the same time, the blue giant sword that Ren Hao had summoned, carrying immense force, also struck those blue vortexes and was immediately blocked. All the sword light and power were also swallowed, with no effect whatsoever.

On the other side, although the black beam of light shot from the black giant gate was also blocked by the blue vortexes, Feng Lin seemed to have anticipated this, and her hands rapidly formed a series of hand seals.

With a "嗡" sound, silver spirit patterns appeared on the surface of the black giant gate, and countless silver runes spewed out from it, merging into the black beam of light.

The black beam of light immediately emitted streaks of silver light, becoming semi-transparent.

With a soft "噗嗤" sound!

Although with some difficulty, the black beam of light still pierced through those blue vortexes and engulfed the blue mermaid's body.

Enveloped by the black beam of light, the blue mermaid's face showed a look of pain, and its movements seemed to be significantly hindered.

Feng Lin formed a hand seal, and the black beam of light trembled. Then, with a "嗖" sound, a huge figure surrounded by demonic energy leaped out from the beam of light.

This demon had a blue face and fangs, was about ten zhang tall, and had two blood-red curved horns growing from its head of blood-red hair. Its hands and feet were covered with scales, and it held a black steel fork, from which black light constantly pulsed.

Although its body was not very large, it exuded an immense and fierce aura that instantly filled the entire hall. It let out a ferocious, sinister laugh, causing Han Li and Ren Hao to feel a tremor in their minds.

"This is one of the thirteen demon kings of the Extra-territorial Demons, Sāpí King! Fellow Daoist Han, be careful. Unlike ordinary Extra-territorial Demons that use heart demon illusions to harm people, Sāpí King can directly injure the soul, making it very difficult to deal with!" Mo Guang's voice rang in Han Li's mind, filled with shock.

Han Li's heart tightened slightly upon hearing this.

"Go!"

Feng Lin shouted and urged her hand seal.

The black light on Sāpí King's steel fork shone brightly, and it stabbed fiercely at the blue merman, who was still moving sluggishly.

With a muffled "砰" sound!

The blue mermaid's body suddenly exploded, turning into a cloud of blue mist that dissipated.

Seeing this, Feng Lin's face lit up with joy, and the hand seal in her hand changed.

A black aura separated from the black beam of light, like a black hand, reaching towards the two treasures in the pool.

Seeing this, Ren Hao's expression changed drastically, but the blue vortexes had not disappeared, and he could only watch as everything happened.

Han Li, seeing this scene, did not make any move after a flash of his eyes.

Just as the two treasures were about to be caught by the black aura, an unexpected change occurred!

The cloud of blue mist that the blue merman had transformed into suddenly solidified and turned back into the blue mermaid, looking as if nothing had happened.

The mermaid grinned, and with a wave of the blue fishing rod, a blue shadow flashed.

With a "砰" sound, the black light exploded.

"How is this possible!" Feng Lin's eyes showed an expression of disbelief upon seeing this.

This "Sāpí Gate" was an ancient Immortal Artifact refining method that she had accidentally obtained from a ruin in the Demon Realm in her early years. She had spent countless efforts to refine it into her Natal Immortal Artifact.

For this Immortal Artifact, Feng Lin had almost exhausted all her savings from the first half of her life, but she did not regret the power of this treasure.

The Sāpí Demonic Light alone was enough to harm the souls of cultivators of the same level, and the Sāpí King it manifested could even injure Taiyi realm existences.

Being simultaneously hit by the Sāpí Demonic Light and the Sāpí King, the blue mermaid was actually unharmed!

At this moment, the blue mermaid waved its arm again, and the blue fishing line flew out again, instantly weaving into a blue fishing net that covered Feng Lin's Sāpí Gate.

Feng Lin was slightly distracted by shock, and her Natal Immortal Artifact was actually imprisoned. Her expression immediately changed, and her hands formed hand seals as fast as wheels.

The sound of "呼呼" rose greatly!

The Sāpí Gate shone brightly with black light, shaking violently, trying to break free from the blue fishing net's restraints.

But no matter how hard it struggled, the blue fishing net tightened more and more, dragging the Sāpí Gate as if dragging a large fish, and quickly flew towards the pool below.

At the same time, two more blue fishing lines flew out from the blue fishing rod with "噗""噗" sounds, wrapping around Han Li's three Green Bamboo Bee Cloud Swords and Ren Hao's blue giant sword.

Having witnessed the power of this blue fishing line, Han Li hurriedly formed a hand seal and pointed.

The surface of the three Green Bamboo Bee Cloud Swords shone brightly with golden lightning, and they shot back with extreme speed, avoiding the entanglement of the blue fishing line.

Ren Hao on the other side also hurriedly recalled the blue giant sword, narrowly avoiding the other blue fishing line.

The two exchanged glances, and both saw a trace of shock in the other's eyes.

This blue mermaid's strength was actually so great that it could still gain the upper hand while facing the three of them at the same time.

Han Li's eyes flickered, and he considered whether to use the Law of Time, otherwise it seemed impossible to defeat this blue mermaid.

Just then, a huge rumbling sound came, but it came from Feng Lin.

She released a black light that formed a black wave, spreading rapidly around and instantly forming a black Spiritual Domain, covering the entire hall in an instant.

Countless black demon shadows flickered within the Spiritual Domain, emitting a painful and shrill scream that made one's scalp tingle.

As soon as the black Spiritual Domain was opened, the Sāpí Gate seemed to resonate, emitting several times the black light, and the two demon god reliefs on it also twisted their bodies as if they had come to life, letting out a huge roar.

The extremely violent power erupted from the Sāpí Gate, causing the nearby void to tremble, and it suddenly stopped.

And under the shroud of the black Spiritual Domain, the blue vortexes around the blue mermaid dimmed a lot, seemingly suppressed by the power of the Spiritual Domain.

Seeing this, Ren Hao's eyes lit up, and his hands also formed a series of hand seals in front of his chest.

Rumble!

Blue light shone brightly on his body, and large swaths of blue light spread around, instantly opening up his Spiritual Domain.

Countless blue waves rolled within his Spiritual Domain, rumbling loudly, like a raging ocean. The blue vortexes around the mermaid dimmed again.

"Fellow Daoist Li!" Ren Hao looked at Han Li and shouted, the meaning was self-evident.

Han Li's eyes flashed, but he still formed a hand seal, and golden light shone brightly around him, with countless golden runes rolling within.

With a wave of his sleeve, the golden light runes spread out with a bang, opening up the Time Spiritual Domain.

"This is..."

"The Time Law Spiritual Domain!"

Ren Hao and Feng Lin felt the Law of Time within Han Li's Spiritual Domain and revealed expressions of shock.

After all, there were three thousand Grand Daos in the world, and each one contained the mysteries of the operation and reproduction of all things in the world. It was extremely difficult to comprehend the various changes within them, often taking tens of thousands of years to have a chance to utilize them slightly by one's own power. And the Law of Time, as one of the three Supreme Laws, was even more mysterious. Not to mention comprehending it, even speculating about its entry was extremely difficult.

And Han Li, as a Golden Immortal realm cultivator with a similar cultivation level to them, not only cultivated and comprehended the Law of Time, but judging from the Spiritual Domain he could mobilize, his comprehension of the Law of Time was obviously not shallow. How could this not surprise the two of them?

The blue mermaid was shrouded by the Time Spiritual Domain released by Han Li, and its movements stagnated. The blue vortexes around it dimmed again, becoming barely visible.

At this moment, a fierce look flashed in Han Li's eyes, and he formed a sword seal with one hand. With a flash of green light, nine Green Bamboo Bee Cloud Swords emerged from his sleeve in succession, turning into nine green giant swords with a spin.

"Chop!" He waved the hand seal.

The nine giant swords fell at the same time, slashing towards those blue vortexes.

Ren Hao had already recovered at this time, and let out a loud shout. The blue giant sword beside him suddenly shot out, radiating a sky-high blue light.

He chanted a spell quickly, and the blue wave shadows in the Spiritual Domain swarmed towards the blue giant sword, merging into it.

The blue giant sword rumbled and trembled, and the blue light on its surface shone brightly again. After a violent tremor, it suddenly disappeared without a trace, and the next moment it appeared out of thin air above the blue vortexes, already transformed into a towering giant sword hundreds of zhang in size. Following Han Li's nine green giant swords, it slashed down!

Although Feng Lin's Natal Immortal Artifact was trapped, she bit her jade teeth at this time and waved her sleeve.

A black seal the size of a fist flew out, its surface shimmering with black crystal light, and a black tiger shadow appeared within it.

She chanted a spell and pressed her hand against the black seal in the void.

Immediately, a shocking tiger roar came from above, and the black tiger shadow circled and danced around the seal, and with a sudden gulp, the numerous black shadows in her Spiritual Domain immediately gathered and merged into the black seal.

The black seal quickly swelled, turning into the size of a house in an instant, radiating a substantial black glow, and slammed down hard towards the blue vortexes.
