These rock monsters indeed possessed astonishing defensive capabilities; facing the fierce laser cannon, they clasped their arms together and managed to withstand the attack.
Only the hands of the Magic Rock Giant blocking the front showed signs of collapse.
Moreover, this collapse was only temporary; a life core with a strong natural aura seemed to exist within the Magic Rock Giant's body, and upon taking damage, the life core immediately activated to restore its wounds.
The destroyed wounds were slowly healing.
What was unexpected was that Chen Yuxuan's powerful strike did not achieve the anticipated effect.
"So tough!"
"As expected of a unit known for its defense, it's truly like a turtle shell."
"The main reason is the gap in levels."
Everyone's brows furrowed slightly.
A level 20 fighting a level 30—the gap in levels and quality was still immense.
The Contract Adventurer' own combat power index was around 3600 points, while these Magic Rock Giants generally had over 6000 points.
In terms of sheer combat power index, it was like a chasm.
Although the Contract Adventurer' equipment was generally better, currently using mostly rare-grade equipment, and even some excellent-grade pink equipment, it only barely managed to narrow some of the gap.
After all, these Magic Rock Giants also had equipment on them.
They might not have top-tier equipment like purple or pink gear, but they definitely had blue or at least basic white gear.
Their equipment forging level also reached level 30, which further widened the gap.
Coupled with the Magic Rock Giant's mastery of defense.
This rendered Chen Yuxuan's cannon shot ineffective.
"It seems it will take some time to clear this Secret Realm; these rocks are indeed a bit troublesome!"
Seeing this, everyone couldn't help but frown.
Chu Ruoxue, meanwhile, flipped to the next page of the manual Chen Yu had given her and calmly said, "Actually, it's not that troublesome. Lord here wrote that the Magic Rock Giant's weakness is also very simple: in the rock crevices of their abdomen, their life core grows, and it is vulnerable to fire and afraid of explosions."
After speaking, she closed the manual in her hand and looked towards the Magic Rock Giant's abdomen.
Sure enough, she discovered some clues.
"So that's it..." Chen Yuxuan's lips curled into a slight smile. "If there's a weakness, then it's simple."
Because they were out and about, the distance was relatively far.
Therefore, the T-Virus could not be used unless it was a critical moment.
Otherwise, after using it, they would have to go back to load, and running back would take some time. Currently, there are no fighter jets developed in Steel Fortress, and relying solely on running on the ground, the speed can only reach 100 kilometers per hour.
This was even in a desperate, frantic running state.
There were no highways here, only mountain roads and plains, so 100 kilometers was the limit.
And without being able to use the T-Virus, the damage would naturally be a tier lower, as talents with side effects are inherently stronger than those without.
"It seems Lord really brought back a lot of important information after this trip. Not only does he have so many Secret Realm coordinates, but he even knows the weaknesses of high-level units like the Magic Rock Giants."
"Since we know the weakness, what's there to fuss about? Isn't it just being vulnerable to fire and afraid of explosions? Watch me..."
Zhang Shiyu immediately became excited. As an Ammunition Expert, her bullets included explosive incendiary rounds that could cause flame explosions.
"I think I understand why Lord spent a fortune to craft sixteen Enchantment Cards - hellfire pino for us before we left. It turns out they were for dealing with these guys."
At this moment, Qi Maosong pulled out an Enchantment Orb from his backpack.
Weapon - hellfire pino
Grants fire attribute attack.
This Enchantment Orb was a treasure crafted by the Sub-profession Enchanter from Dungeon and Eight Million Warriors.
Its purpose was to enchant equipment, granting additional attribute bonuses.
And this Enchantment Orb hellfire pino, back in the Version 60 era, was also extremely expensive, valued at tens of millions of gold coins.
With this Enchantment Orb enchanted onto their weapons, the Contract Adventurer' weapons immediately emitted a red glow.
Fire attribute attack!
From now on, every attack they launched and all damage they dealt would have an additional fire attribute explosion effect.
Chen Yuxuan directly abandoned the Gunner's heavy weapons, letting Chu Ruoxue transform into a sniper rifle, and aimed at the Magic Rock Giant in the direction of the altar, firing a shot directly at its abdominal weakness.
"Bang!"
A shot rang out.
A Magic Rock Giant fell in response, turning into a pile of stones.
The effect of this weakness exceeded their imagination.
The Magic Rock Giant appeared indestructible, but this also made its weakness extremely fragile; once subjected to fire attribute explosion attacks, it was a fatal blow.
With this shot, the Magic Rock Giant on the opposite side was clearly somewhat flustered.
It seemed they hadn't expected someone to discover their weakness so quickly.
They hurriedly used both arms to block their abdomen.
But...
The weakness had already been discovered; blocking it was futile.
Their own attack capabilities were already relatively poor, and now, if they used both hands to block their weakness, they would essentially have no attack capability whatsoever.
They became like a turtle shell, only able to passively endure attacks.
And passive defense merely delayed death...
The sixteen Contract Adventurer took turns unleashing colorless skills and awakening skills. Under their continuous bombardment, the Magic Rock Giant's arms simply couldn't withstand it for long and were directly forcibly dismantled.
While they had not yet recovered, the Contract Adventurer seized the opportunity to destroy their life cores.
The number of Magic Rock Giants accumulated in this Secret Realm was quite substantial.
The sixteen Contract Adventurer fought their way from the entrance to the interior, possibly killing dozens of them, and their weapon durability was almost at zero before they finally cleared out all the Magic Rock Giants.
Afterwards, the Contract Adventurer thoroughly cleared out all buildings deep within the Secret Realm, completely erasing Guo Quan's traces in this Secret Realm.
"Another Secret Realm destroyed."
"This Secret Realm is quite large; the target must have suffered heavy losses this time and is probably jumping with anxiety right now."
"Let's go, no more chitchat!" Li Ruoshu said indifferently, "Let's find a wilderness blacksmith to repair our equipment, and then continue to the next target point, striving to kill this target as soon as possible."
After speaking, the figures of the sixteen Contract Adventurer disappeared into the swamp.
At the same time, Guo Quan, far away in a certain castle, saw another one of his Secret Realms disappear, becoming blank.
This sent a chill through his heart, and cold sweat broke out on his back.
"What exactly is going on?"
Guo Quan gritted his teeth, looking at his remaining few Secret Realms, his eyes filled with both anger and fear.
