Han Li quietly gazed at the scene before him, his expression somewhat complex.

After this sword strike, the golden lightning on the giant sword dissipated completely, as if it had exhausted its power.

However, the power of this sword faintly resembled the former Profound Severing Spirit Sword. If this single flying sword possessed such power, what would be the extent of its might if all seventy-two were unleashed simultaneously?

At this thought, a surge of excitement welled up within him.

However, merely controlling this single flying sword had already consumed nearly all of his immortal spiritual power and divine sense, making it unlikely that he could wield other flying swords.

Thinking of this, Han Li's initial fervent excitement quickly waned.

Suddenly, something flashed in his mind, and he recalled the earlier instance of the flying sword automatically entering his dantian. His eyebrows twitched involuntarily.

Perhaps the situation wasn't as he had imagined?

With a thought, Han Li enveloped the other seventy-one flying swords within his dantian and slightly urged them.

The surfaces of these flying swords merely flickered with a faint green light, yet they remained motionless.

After a moment of contemplation, he mobilized the immortal spiritual power within his dantian and forcefully urged them once more.

As a result, the green light on the surface of all the flying swords continued to flicker as before, yet they remained as firmly rooted within his dantian as if they had grown there.

Seeing this, Han Li sighed, silently acknowledging that his assumption was indeed correct.

The flying swords within his dantian now felt incredibly heavy. With his current immortal spiritual power, it was like an ant trying to move a mountain, utterly impossible to budge them.

Fortunately, the Green Bamboo Cloudswarm Swords still maintained their connection with his mind. Once his strength increased in the future, he would be able to control these flying swords.

After sighing softly, he ceased trying to unleash all the flying swords at once, and instead concentrated his divine sense once more, summoning another sword.

Several flashes of green light appeared before him, and a green flying sword materialized.

Han Li took a deep breath, channeling all the immortal spiritual power within his body and the power of his divine sense in his mind, and executed a sword incantation with his hand.

The surface of this Green Bamboo Cloudswarm Sword rippled with a bright green light, and it quivered a few times, but ultimately failed to fly forth.

On the contrary, due to the excessive exertion of his immortal spiritual power and divine sense, he suddenly felt a wave of dizziness in his mind. Alarmed, he quickly stopped.

Han Li waved his hand and retracted the flying sword, his gaze flickering.

It seemed that with his current strength, wielding even a single Green Bamboo Cloudswarm Sword was his limit.

The giant green sword slowly rotated in mid-air. Although it no longer possessed the violent golden lightning arcs, it still emanated a mountain-like, sea-like pressure.

However, even though there was only one, the power of this single Green Bamboo Cloudswarm Sword was no less than that of the entire set of flying swords from before.

With a wave of his hand, the giant green sword flew down, rapidly shrinking and transforming into a green sword that entered his sleeve.

His figure swayed and he descended.

A delicate figure was standing below, none other than Lu Yuqing.

"Congratulations, Brother Han, the power of your flying sword has greatly increased." Seeing Han Li descend, Lu Yuqing greeted him with a smile.

"It was all just a stroke of luck. Now that you're here, have you dealt with the puppets from before?" Han Li said with a faint smile, vaguely.

Lu Yuqing didn't say much, simply nodded.

At this moment, all the strange phenomena in the sky disappeared, and the entire secret realm became extremely quiet. The white clouds that had been dispersed by the Green Bamboo Cloudswarm Sword in mid-air slowly returned to their original state.

"It seems that there are no other treasures here. We've been in here for quite some time. Although the entrance to this secret realm is hidden, it's hard to guarantee that Xue Han and the others won't follow us in. We should leave this Underworld Frost Palace as soon as possible." Han Li looked around and said.

Hearing this, Lu Yuqing paused slightly, and a hint of hesitation appeared on her face.

"Does Miss Lu perhaps have unfinished business here?" Han Li asked, seeing Lu Yuqing's expression.

"No, Brother Han, you're right, we should leave as soon as possible. But please wait for me for a moment." Lu Yuqing said, her figure flying towards the lone Taoist temple standing there, landing in front of the Ancestral Hall.

She waved her hand and emitted a surge of green light, enveloping all the memorial tablets there and collecting them.

Having done this, she immediately turned around and flew back.

"Let's go." Han Li naturally saw all of Lu Yuqing's actions, and a hint of surprise flashed in his eyes, but he didn't ask any further, simply saying indifferently.

After saying this, his figure shot out, heading down the mountain.

Lu Yuqing's body shimmered with green light, and she followed behind.

Perhaps because the white altar in mid-air had been destroyed, or perhaps because all the flying swords in the Sword Sea had disappeared, the boundless sword energy in mid-air had also vanished.

Without the boundless sword energy in the sky, it was now possible to fly freely here.

Just as the two of them took flight, a loud bang came from deep within the secret realm, like a muffled thunderclap. The entire secret realm shook violently.

"What's going on?!" Han Li's expression changed slightly. He stopped and looked in the direction of the loud bang.

A white beam of light emerged there, shooting straight into the sky.

This white beam of light was extremely thick, at least several tens of feet in diameter, like a pillar supporting the heavens.

Waves of immense spiritual power emanated from the beam of light. Even Han Li felt a bit alarmed.

"This..." Lu Yuqing looked at the white beam of light in the distance, her face filled with shock.

Boom!

Another muffled thunder-like roar came from another direction, and the entire secret realm shook violently once more.

Another thick white beam of light emerged there, also shooting into the sky.

Han Li and Lu Yuqing turned to look, their faces once again showing surprise.

The two beams of light faintly echoed each other, and the entire secret realm began to tremble, with the tremors becoming increasingly intense.

The entire giant peak also rumbled and shook, and countless pieces of rock rolled down from the mountain, like a rain of stones.

"Not good, this secret realm may be about to collapse, let's go!" Han Li's expression changed, and he shouted suddenly. A surge of green light erupted from his body, and he shot towards the foot of the mountain like lightning.

Hearing this, Lu Yuqing's pretty face also changed, and she hurriedly followed.

As they fled, thoughts raced through Han Li's mind. How could this be happening?

Could it be that the collapse of the white altar triggered the collapse of the secret realm, or did his earlier void sword strike destroy some important linchpin of this secret realm?

He shook his head. Thinking about the reasons now was superfluous. It was best to leave this place as soon as possible.

The green light on Han Li's body intensified again, and his speed immediately increased slightly.

With their speed, they quickly flew to the bottom of the mountain, arriving at the place where they had entered the secret realm earlier.

At this moment, three more white beams of light rose up in another direction of the secret realm, and the trembling of the entire space intensified a great deal.

Han Li released his divine sense and swept through this area and the surrounding area, his expression slightly sinking.

This space was extremely stable, and there was no space channel or teleportation formation that could be used to leave.

He had always thought that this was the entrance and exit of the secret realm, but it seemed that he had guessed wrong.

Sensing the situation here, Lu Yuqing's face was also extremely unsightly.

"Miss Lu, in the past three days, I've seen you moving around in various places on the mountain. Have you discovered any other exits, or anything unusual?" Han Li looked at Lu Yuqing and asked suddenly.

"No, this secret realm seems to have been explored by that Xiong Shan. I only saw some dilapidated buildings in various places. Almost all the restrictions have been broken, and there is nothing unusual inside." Lu Yuqing shook her head.

Hearing this, Han Li turned to look at the void in front of him.

With his current supernatural powers, it was not yet possible to break open the void here and open a space channel.

The space in the Immortal World was extremely stable, not comparable to the lower realms like the Spirit World.

Moreover, even if he broke open the space here, he might not be able to reach the outside world. He might be swept into the endless void turbulence and die without a burial place.

Just at this moment, with a loud "boom," a fourth white beam of light appeared in another direction of the secret realm.

The four thick beams of light echoed each other, and the entire secret realm shook violently.

A harsh "crackling" sound came from overhead, and white cracks suddenly appeared in the void, like cracks on a mirror, quickly spreading around.

Seeing this scene, Lu Yuqing's face suddenly turned pale.

"Since this space is used for refining swords, there must be an exit. Time is of the essence, let's split up and look around." Han Li said in a deep voice.

Before the sound of his voice had faded, his figure shot off in one direction.

Lu Yuqing nodded and immediately flew off in another direction.

After flying out a short distance, the woman suddenly stopped, a hint of doubt appearing on her face as she looked towards a certain place on the mountainside.

After hesitating for a moment, a surge of green light erupted from her body, and she shot towards that place.

At the same time, Han Li flew along one side of the giant peak, heading towards the peak.

His divine sense spread out, and a blue light burst forth from his eyes, shooting out two blue beams of light, looking downwards.

Not only that, he muttered something, and a golden light flashed before him as he used the Eye of Truth to investigate everything around him.

With his speed, he quickly explored most of the mountain, and suddenly stopped abruptly.

Continuing upwards, all the vegetation had been uprooted by the previous storm, revealing bare mountain walls that could be seen through at a glance, and there was nothing there.

Han Li looked towards the top of his head.

At this moment, no new white beams of light had appeared, but the white cracks in the void were spreading rapidly, and were becoming increasingly thicker.

The trembling of the entire secret realm became even more intense, and gusts of wind had begun to stir up everywhere.

Han Li felt a sense of urgency and immediately changed direction, exploring the other side of the giant peak.

"Brother Han, come to me quickly." Just at that moment, a voice rang out in his mind, it was Lu Yuqing.

Han Li was stunned, turned to look downwards, and his figure swayed, transforming into a streak of green light and flying downwards.

Lu Yuqing was standing at a certain point on the mountainside of the giant peak, black light flashing in her eyes, looking at a mountain wall in front of her.

With a flash of green light, Han Li's figure appeared.

"Miss Lu, have you discovered anything?" He looked in the direction of Lu Yuqing's gaze, blue light flashing in his eyes, but he found nothing.

A golden light flashed before him, and the Mantra Treasure Wheel emerged, the Eye of Truth in the center flashing with countless golden light spots, looking towards the mountain wall.

The next moment, a look of joy suddenly appeared on his face, and he flicked his finger.

With a "whoosh!"

A cyan sword Qi shot out, hitting the mountain wall.

The sword Qi flashed and disappeared into it, vanishing without a trace, but then a white light rippled on the surface of the mountain wall, and then strangely flickered again and disappeared.
