To get the treasure chest, you must break through the ice layer.

But once the ice layer is broken, it will disturb these monsters.

Zong Shen stood outside the small ice mountain and extended his right hand to gently stroke the ice surface.

Through the chain armor gloves, he could feel the coolness gradually coming to his palm.

This is genuinely solid ice, frozen hard as rock.

However, this thing has some peculiarities because it won't melt under heat.

Despite being directly hit and illuminated by sunlight, it shows no sign of melting.

Zong Shen withdrew his hand, and the snow leopards trapped inside the ice mountain were restless.

Bearing down on the ice surface with their fan-sized sharp claws madly.

Even through the super-thick ice, Zong Shen could vaguely hear their roars.

"Impulsive creatures."

Zong Shen tilted his head, his eyes fixed on these snow leopards.

[Tier Three Icefield Snow Leopard lv20 (Blue)]

[Blue Captain Level]

[Race: Icefield Beasts]

[Tearing Bite Damage: 41~44]

[Life Value: 785]

[Armor Value: 30]

[Magic Resistance: 25]

[Speed: 6]

[Passive Skill: Frost Damage (attack carries an extra 20 points of frost damage, able to create a certain freezing effect)]

[Points: 125]

(Icefield beasts guarding the treasure chest, captain-level monsters, not too tough for you)

Zong Shen glanced at the attributes of these creatures; apart from the slightly high life value, the other attributes were inferior to the Sentinel Black Panther, but they were still considered relatively strong beasts.

Moreover, they had a numerical advantage and could gang up on Zong Shen.

Zong Shen showed no reaction, he summoned the [Wind-Fire-Thunder Trident] and started hitting the small ice mountain with the tapered impact head.

Using eighty percent of his strength, he only managed to leave a rice bowl-sized hole.

The hardness of this ice mountain exceeded imagination; it seemed that obtaining the Frosty Winter Treasure Chest's challenge was far more than just the guarding icefield beasts; the small ice mountain was also part of the test.

Unaffected by the temperature brought by sunlight, it also possessed extraordinary hardness.

Dealing with this ice mountain is really not easy.

If using brute force to chisel, who knows how long it would take.

Thinking of this, he turned around and looked at the drilling machine behind him.

The three groups of grim drill bits should be able to drill through this ice mountain.

Considering the hardness of this thing, it might greatly reduce the durability of the drill bits.

Now the third stage of Frosty Winter had just started for less than half an hour.

Upon first seeing the small ice mountain, he had ample time to study it.

Selecting the best plan to break the ice mountain.

Upon his scrutiny, this block of ice mountain did not show any related attributes.

It did not possess the concept of durability value and armor value; it was a non-datified substantial product.

Proving that this small ice mountain was entirely different from the Rune Gate.

Zong Shen took two steps back, looked at the living area, and climbed into the cockpit, driving towards the living area with Aisha.

He directly drove the drilling machine to Doris's side, inviting her into the cockpit.

He let her squeeze in with Aisha and drove back towards the small ice mountain.

The empty space in the cockpit was like the water of a sponge; there's always some when squeezed.

He hurriedly returned to the small ice mountain and pulled Doris down from the cockpit.

"Doris, spray fire here."

"I want to see what this ice mountain is all about."

Zong Shen pointed at a plane of the small ice mountain, letting Doris prepare to "spray fire."

He wanted to know the specific properties of the ice mountain made by the system, which could not melt under sunlight.

Actually, there were two possibilities for this situation, one was that the melting point of this ice mountain was relatively special, higher than ordinary ice and snow, and the other possibility was that it simply wouldn't melt.

With the Lord System's capability, creating some ice mountains with unconventional rules and traits wasn't too astonishing.

Zong Shen stepped back over ten steps, waiting for Doris's demonstration.

Doris was very cooperative with his request.

She held the [Scorching Burning Staff], aimed the top at the ice surface, and adjusted the angle.

A fire dragon slightly thicker than her arm surged out, hitting one side of the small ice mountain straight, affected by the Frosty Winter climate, the fire dragon originally thigh-thick now was only slightly thicker than an arm.

The fire dragon was surging and intense, like an orange-red scorching fire stream, erupting and blossoming into a flame flower on the ice surface.

Some flames overflowed from the sides, showing slight signs of backdraft.

Zong Shen stared unblinkingly at the contact surface between the small ice mountain and the fire dragon.

After two or three seconds, the ice surface began to melt rapidly, like a block of butter entering a pot.

About twenty seconds later, the small ice mountain had been burned into a two-meter deep hole.

"Stop now, Doris."

Zong Shen waved his arm, signaling Doris to stop.

He quickly approached, reaching out to touch the irregular congealed ice layer beside the melting opening.

With a clear conclusion in his mind.

The small ice mountain containing the Frosty Winter Treasure Chest wouldn't completely not melt, under the sustained baking of the high-temperature fire dragon, it would also show melting.

However, compared to ordinary ice blocks, the heat resistance of these small ice mountains almost rivaled that of metal.

The wind furnace usually used in the Blacksmith Shop for smelting iron ore had a temperature of about 1500°C.

Zong Shen wasn't sure how high the fire dragon's temperature was just now, but under such concentrated fire flow, the temperature certainly wouldn't be low.

Under such conditions, it took over twenty seconds to burn a two-meter deep hole.

Moreover, the melted hole wasn't actually large, only half a meter in diameter on the outer side, reaching only arm thickness at the deepest.

This was rather ridiculous, to rely on the fire dragon to burn to the center of the ice mountain and open up a passage wide enough for at least one person would take seven to eight minutes.

In this case, it would be more straightforward to directly use the drilling machine, after all, the "flamethrower" skill also consumes the durability of the staff.

However, the "flamethrower" does have some usefulness.

These icefield beasts are trapped inside the small ice mountain, and Zong Shen can completely adjust the entrance size to "trap monsters," he only needs to open up a cramped passage.

Let these snow leopards come out one by one to meet their fate.

The first part can be excavated using the Magic Energy Drilling Machine, and when it's almost open, let Doris continue to use "flamethrower" to melt a small passage.

"Doris, Aisha, both of you step back."

"Prepare to assist me."

Zong Shen quickly instructed, and then he climbed into the cockpit using both hands and feet.

Pushed the power of the drill bit to level three.

[Magic Energy Drilling Machine] has both its magic energy core power and drill machine power divided into three levels; level one is the highest power, level three is the lowest.

The three groups of drill bits began to slowly rotate, with airflow-stirring sounds and gear rolling sounds emerging.

"Buzz... buzz..."

Zong Shen drove the drilling machine forward, aiming at where Doris sprayed fire just now, slowly moving up, and the front drill bit touched the ice surface, making a piercing friction noise.

The alloy-crafted drill tip quickly broke open a breakthrough.

As the [Magic Energy Drilling Machine] slowly advanced, the thick main drill bit pushed forward.

Ice shards flew everywhere and once separated from the main body of the ice mountain, melted into drops of water.

When the main drill bit was halfway in, the auxiliary drill bits on either side also began contacting the ice surface.

This [Magic Energy Drilling Machine] can drill out circular or semicircular passages with diameters of about three meters.

Once the third level's rotation speed stabilized, Zong Shen pushed the lever for the second level's power.

The drilling speed increased and the torque increased considerably.

Under such conditions, he quickly opened up a six to seven meter deep passage.

This depth was only about half a meter of ice layer away from the unfrozen center circle.

Those snow leopards inside also became increasingly frenzied.

Continuously pouncing at the ice wall.
