Now, thanks to the runes in his palm, Shen Yunhao can finally travel freely between the blue and white caves.

However, using the access control rune requires a certain amount of spiritual energy, but for Shen Yunhao, the consumption is not significant.

Moreover, the runes in his hand could only open the white ice crystal wall, but had no way to deal with the other three blue ice crystal walls.

"Including the first four, and the next six... that means every ten blue crystals can activate one rune?"

With that in mind, Shen Yunhao continued to project blue crystals into the light screen.

Sure enough, after another ten blue crystals were added, another rune lit up and then disappeared into Shen Yunhao's palm.

The word "ban" is still there, only its color has darkened.

This time, there was no need to hesitate. Shen Yunhao quickly went to try out the three blue ice crystal doors.

They discovered that the door on the left could be opened, but the other two remained closed.

Moreover, even if Shen Yunhao put all the remaining blue crystals into the light screen and activated two more runes, he still couldn't open the other two.

"From what we can see now, the situation is very clear... Thirty-six runes require a total of thirty-six blue crystals to activate. Defeating the ice beasts in the white cave will only yield forty-three crystals, enough to open only the left door... The remaining blue crystals will need to be obtained by defeating the ice beasts in the left cave!"

Having figured this out, Shen Yunhao stood in front of the ice gate on the left, took a deep breath, and stepped through the ice wall without hesitation.

The access control rune can melt the ice wall to create a small hole for people to pass through. To expand it, it is necessary to continue consuming spiritual energy.

The small hole won't disappear immediately, so if there's danger on the other side of the ice wall, Shen Yunhao can quickly return to the blue ice cave.

Therefore, the doorway should not be too large, to prevent the ice beasts from passing through the ice wall and causing him trouble...

Shen Yunhao passed through the ice gate and found himself in a brand new ice cave. The ice crystals were also ordinary white, but this cave was different from the one he had been in before. It was not a circular space, but a long tunnel that could be continuously extended.

After observing for a while, Shen Yunhao sensed that something seemed to be moving deep inside the cave.

He quickly concealed his breathing, knocked off a large ice crystal from the side to block his way, and silently advanced into the cave.

Although I don't know if the ice beasts here also only have heat sensors, just to be on the safe side, I'll cover them with a piece of ice crystal!

Moreover, the cultivation level of the ice beasts here is definitely no lower than that of the three they encountered before. In a head-on confrontation, Shen Yunhao would be no match for them, so he must proceed with caution.

As Shen Yunhao ventured deeper, the temperature dropped further and further. His breath condensed into tiny ice crystals the moment it left his lips, and strange scratches began to appear on the cave walls, as if they had been scraped by something huge and sharp.

After turning a corner, Shen Yunhao finally saw his target in front of him... It was a huge white crystal beast.

The giant beast resembles a tiger, its entire body made of translucent white ice crystals. It is lying on a protruding ice platform, seemingly in a dormant state.

Is this the only one?

Shen Yunhao quietly grabbed the fox's tail and activated his true vision. He discovered a distinct blue core on the beast's abdomen and chest, which should be the beast's weak point.

What caught his attention, however, was that there were scattered ice crystal fragments around the tiger-shaped behemoth, which, combined with the claw marks he had seen on the wall earlier...

"Could it be... that these behemoths can fight amongst themselves? This guy killed the other two?"

Shen Yunhao frowned. "But if we kill it, what about all the blue crystals that exploded? Could it be that the giant tiger devoured them all?"

After thinking for a long time, I still couldn't find a clue.

"The combat strength of this behemoth is unknown. If it's as agile as the Ice Crystal Sable, then I'm doomed today. I have to find a way to test it out first..."

However, just as he was racking his brains for a solution, the tiger-shaped behemoth's ears suddenly stood up, and its ice crystal eyelids snapped open, revealing a pair of sapphire-like eyes!

Shen Yunhao's heart tightened, and he immediately concealed his aura to the extreme behind the ice crystal.

This behemoth... seems to have eyes! It can see!

This was undoubtedly terrible news for Shen Yunhao.

However, the giant beast on the ice platform did not notice him, but instead turned its head towards the passage on the other side of the cave.

The next second, a dark figure emerged from the passage like a ghost, accompanied by a crimson light that pointed directly at the tiger's head and brow.

Shen Yunhao was shocked... There were other people here!

"bite!"

The shadowy figure was incredibly fast; the giant tiger seemed to have no time to react before a jet-black longsword pierced its head.

Unfortunately... the tiger's brow was not its weak point. Although the powerful sword pierced through, it only made the beast more frenzied.

"roar!"

The giant tiger roared and raised one of its crystal-formed forelimbs, slamming it down hard on the dark shadow in front of its forehead.

This palm strike was incredibly fast, creating a sonic boom!

This single claw strike is far more powerful than the giant python's strength... It has at least the attack power of a late-stage Soul Control Realm cultivator!

The dark figure naturally dared not take the attack head-on, and immediately drew its sword and flew away, barely dodging the claw, revealing itself in mid-air.

Only then did Shen Yunhao see clearly that the attacker was completely shrouded in a black cloak, making him appear blurry in the already dark cave. He wore a silver mask, revealing only a pair of eyes, and held a jet-black longsword in his right hand, the blade of which was covered with strange blood-red runes.

"What a thick-skinned beast... I refuse to believe I can't deal with you!"

The man in black spoke slowly, his voice unusually hoarse.

Shen Yunhao hid in a corner, barely daring to breathe. From the man in black's words, he had clearly already encountered other giant beasts.

Perhaps he was the one who killed the other two giant beasts in this cave!

The tiger-shaped behemoth let out a low roar, slowly stood up, and the ice crystals all over its body made a crisp clanging sound.

The man in black remained calm and took out a golden talisman from his pocket. In an instant, the temperature in the entire cave seemed to rise a few degrees.

"Holy crap! What kind of talisman is this? It can actually suppress the cold air here?"

Shen Yunhao was startled.

The man in black bit his tongue and spat a mouthful of blood onto the talisman. The talisman immediately shone with golden light and transformed into a three-zhang-long fire dragon, roaring as it pounced on the giant beast.

Wherever the fire dragon passed, the white ice crystals instantly vaporized, turning into wisps of white vapor that drifted away.

However, when faced with the fire dragon, the tiger-shaped behemoth suddenly opened its mouth and spewed out a stream of blue cold air, which collided with the fire dragon and produced a deafening roar.

At the same time, the man in black did not slacken his pace. Instead, he transformed back into a black shadow, wielding a long sword and launching a surprise attack on the giant tiger's back!

"Clang!"

The sword pierced it, and he shattered several ice crystals!

"Strange...why is his shot hitting such an off-center spot?"

Shen Yunhao murmured softly, then suddenly realized what he meant.

"Without the fox tail, this guy can't see the giant tiger's core weakness at all!"
