After a brief adjustment, Wang Fan and Bing Mei swam along a hidden current at the bottom of the lake.

This undercurrent is like a mysterious passage leading to the unknown, with the surrounding water flowing rapidly and occasionally some strange lights and shadows flashing by.

After swimming for an unknown amount of time, a huge whirlpool appeared ahead.

The whirlpool emitted a ghostly blue light, blending seamlessly with the surrounding cold lake water, as if it were an entrance to another world.

Wang Fan and Bing Mei exchanged a glance, understanding each other perfectly. After taking a deep breath, they resolutely swam into the whirlpool.

Under the powerful suction of the vortex, the two people's bodies spun rapidly and uncontrollably.

They felt dizzy and everything around them became blurry.

Suddenly, a flash of light appeared before their eyes, and they were violently propelled by a force, landing heavily on a cold patch of ground.

Wang Fan and Bing Mei quickly stood up and cautiously looked around.

They found themselves in a huge ice cave, its walls inlaid with countless ice crystals that emitted a ghostly blue light.

These ice crystals come in various shapes and sizes, some as sharp as swords and others as blooming as flowers, making the entire ice cave look like a dream.

"This should be the Azure Ice Cave, right?" Wang Fan asked in a low voice, his eyes scanning the cave for any potential dangers.

“According to my father, this should be the place.” Bingmei’s expression was solemn, and a trace of recollection was revealed in her eyes. “He mentioned that there is an undercurrent at the bottom of the lake, and after passing through it, you will reach an ice cave.”

Ice Fairy paused, her gaze slowly sweeping across the deep blue ice cave, before continuing, "If we can get through here safely, the next stop is the Illusion Crystal Vineyard. But the deep blue ice cave is fraught with danger; we'll encounter all sorts of traps and mechanisms inside."

"Some mechanisms are hidden beneath the ice; once triggered, ice spikes may erupt from all directions."

"Some mechanisms can manipulate the airflow inside the ice cave to create powerful storms that can sweep people in and make it difficult for them to escape."

Wang Fan frowned, gripping the Bloodthirsty Halberd tightly, but there was no fear in his eyes. "It seems this journey is destined to be anything but easy."

"But now that we've come this far, we must overcome whatever difficulties we encounter. Ice Charm, do you know of any clues here to solve the puzzles?"

Bingmei shook her head slightly. "Father only mentioned that this place is dangerous, without mentioning how to break the mechanisms. But I think that since these mechanisms are for protecting the seal, they may be related to some special arrangement inside the ice cave."

"As we move forward, we must pay close attention to our surroundings; we might discover some clues."

Wang Fan nodded. "Okay, let's continue forward and remain vigilant."

The two continued cautiously into the depths of the ice cave, taking each step with extreme care.

The ice cave was eerily quiet, with only their soft footsteps echoing between the ice walls.

Suddenly, Wang Fan felt an unusual vibration coming from the ice beneath his feet.

He was startled and shouted, "Ice Demon, retreat quickly!"

Ice Demon reacted extremely quickly, lightly touching the ice with her toes and retreating backward like a swallow.

Wang Fan also quickly used his movement technique to leap backward.

However, the ice spikes grew extremely fast, and one of them grazed the corner of Wang Fan's clothes, tearing a hole in the fabric.

After landing, the two dared not relax for a moment and kept their eyes fixed on the ice spikes.

After the ice spikes stopped growing, their surface began to shimmer with a ghostly blue light.

Immediately afterwards, the light transformed into runes that flowed along the ice spikes.

“These runes seem to be brewing something.” Ice Charm looked tense, her eyes fixed on the runes, trying to discern any clues.

Wang Fan nodded slightly, gripped the Bloodthirsty Battle Halberd tightly, and remained fully alert.

Just then, the runes shone brightly, and the ice spikes detached from the ground.

It shot towards Wang Fan and Bing Mei with lightning speed.

Wang Fan shouted and brandished the Bloodthirsty Battle Halberd, forming an impenetrable defense in front of him.

The crimson halberd clashed with the ice spikes, producing a crisp clanging sound, and ice shards flew everywhere.

Ice Demon rapidly formed hand seals while chanting incantations.

The surrounding air instantly condensed into a thick ice shield, protecting her within it.

However, the ice spikes were numerous, coming in waves.

Wang Fan felt his arms gradually becoming heavy, and each time he blocked, it took a lot of effort.

On Ice Charm's side, the ice shield also began to crack under the impact of the ice spikes.

"This can't go on, we have to find a way to break this deadlock!" Wang Fan shouted, large beads of sweat rolling down his forehead.

Ice Demon's gaze swept quickly around, then her eyes suddenly lit up. "Wang Fan, look at the direction those ice spikes are firing. They all seem to be centered on that blue crystal! Maybe destroying it will stop the attack!"

Following the direction Bingmei pointed, Wang Fan saw a crystal emitting a dazzling blue light embedded in the ice wall not far away.

Without the slightest hesitation, he concentrated all his strength into the Bloodthirsty Halberd and then hurled it with force.

The Bloodthirsty Halberd transformed into a streak of blood-red light, shooting towards the blue crystal like a cannonball.

With a loud "boom," the crystal was struck and instantly shattered into countless fragments.

The attacking ice spikes lost their momentum and fell, shattering on the ice.

Wang Fan retrieved the Bloodthirsty Halberd and breathed a long sigh of relief.

Ice Charm put away her ice shield and walked to Wang Fan's side. "It seems that the mechanisms in this Azure Ice Cave are far more complex than we imagined. We need to be even more careful from now on."

Wang Fan nodded solemnly, "That's right, this is just the beginning, and we don't know what other more troublesome situations might arise later."

The two continued onward, and the temperature inside the ice cave seemed to drop even further, their breath instantly condensing into icy mist.

The surrounding ice walls became increasingly crystal clear, but beneath this beautiful appearance lurked a deadly crisis.

As we walked, a narrow ice path appeared ahead.

On the walls on both sides of the ice track, at intervals, there is an ice bead that emits a faint glow.

The ice beads shimmered at different rhythms, some fast and some slow, as if conveying some mysterious signal.

Ice Demon looked at the ice beads warily. "These ice beads are a bit strange."

Wang Fan nodded slightly, his gaze fixed on the shimmering ice beads. "Hmm, their shimmering is completely unpredictable; there must be some hidden secret behind it."

"If we walk up there rashly, we might trigger a trap."

As he spoke, he crouched down and carefully examined the ice track floor, trying to find some clues or flaws.

But apart from the smooth ice surface, nothing was found.

Ice Fairy paced around the ice path, her eyes taking in every single detail.

Suddenly, she noticed some faint patterns on the wall on one side of the ice track, which looked like some kind of ancient script.
