Just as everyone was shocked by Sunan's thunderous methods, Sunan himself was not too satisfied.
"If my Spiritual Power were a bit higher, that last Acid Splash could have killed the Iron Devourer."
Sunan felt a bit regretful, pointed his hand, and another Acid Splash shot out like an arrow towards an Iron Devourer.
Sizzle! Sizzle! Sizzle!
Although the Iron Devourer dodged in time, it was still hit on the side, instantly corroding away most of its waist, inevitably affecting its movements.
Taking this opportunity, Kei dashed forward and sliced the Iron Devourer into two.
The brothers cooperated seamlessly, and within a short moment, they had taken down four Iron Devourers.
The group felt a surge of morale upon seeing this.
The Iron Devourers seemed to realize something was amiss and began to retreat.
Noticing this, Kei shouted quickly: "Don't let them escape, stop them!"
The knights rushed towards the Iron Devourers.
Sunan squinted his eyes, targeting the last Iron Devourer, and cast a Sleep Spell.
But to his surprise, that Iron Devourer was completely unaffected.
"The magic didn't work?"
Sunan was stunned.
At that moment, an Iron Devourer suddenly leapt, disappearing into the rock wall as if diving into water, the whole process so seamless that everyone had no time to react.
The remaining Iron Devourers followed suit, disappearing into the rock walls.
As the last Iron Devourer lunged towards the rock wall, the stunned Sunan finally reacted, a glint flashing in his eyes.
In an instant, the graceful figure of the Iron Devourer came to an abrupt halt, suspended in mid-air as if gripped by an invisible giant hand, unable to touch the ground or walls.
No matter how it struggled, it couldn't break free from the invisible binding on its body.
"Finish it off!" Sunan spoke in a deep voice.
The astonished group snapped out of their daze and made their moves.
Crack!
The Iron Devourer in mid-air was shattered instantly.
"Sunan, just now..."
Kei looked at Sunan, full of amazement.
If the Minor Dragon Blood Potion was within his understanding, then the miraculous methods Sunan displayed just now far exceeded his knowledge.
Sunan knew what he wanted to ask and explained calmly: "It was magic."
Magic!
Everyone present silently pondered this word, feeling as though a brand new world was slowly unfolding before them.
Ignoring the others, Sunan quickly approached an Iron Devourer that had been sliced in two, squatting down to inspect it.
A moment later, a strange expression appeared on his face.
"Is there something wrong?"
Seeing Sunan's expression, Kei hurriedly asked.
Sunan shook his head, stood up, and said, "I probably know how these Iron Devourers came to be."
When the Sleep Spell failed to work earlier, he already felt something was off.
There are generally only two scenarios that can be immune to magic.
One is if the creature's Spell Resistance is high enough, like the Dragon Race.
The Dragon Race is famously resistant to low-level magic; adult dragons can be immune to all Tier Three spells and below.
The other scenario is if the life form's nature happens to be immune to certain magic.
For example, creatures like Elemental Creatures, undead, and golems are immune to the Sleep Spell.
And the Iron Devourers were clearly of the latter category.
"Initially thought they were a metallic life form, but it turns out they are golems."
During his inspection earlier, Sunan discovered Enchanted Runes within the Iron Devourer's body fragments.
Naturally occurring life forms cannot possess Enchanted Runes.
The only explanation is that the Iron Devourers were artificially created!
And only Wizards (or Wizard Apprentices) can create golems!
"There is likely a Wizard's legacy deep in this mine!"
Sunan felt a surge of elation.
He originally planned to seek out the whereabouts of a Wizard's legacy after advancing to a second-tier Wizard Apprentice, and never thought there would be one near Black Stone City.
This was undoubtedly a huge surprise!
With Sunan's explanation, Kei and the others displayed expressions of absolute shock.
No one expected that these Iron Devourers, whose combat effectiveness rivals that of knights and possesses the bizarre ability to burrow into rock walls, were actually golems created by Wizards!
Magical potions, frightening magic, powerful golems—these are unimaginable things to ordinary people, yet they all originated from Wizards!
What kind of group is this?
The more they understood, the more they felt the mystery and power of Wizards.
Legend has it that thousands of years ago, Wizards once ruled the entire continent and created an unprecedented era of prosperity.
What used to be dismissed as mere legend now seemed increasingly likely to be true!
Each with their own thoughts, the tunnel fell into silence.
Sunan paid no heed, saying something to Kei before sitting on the ground to meditate and recover his Spiritual Power.
The recent battle had consumed considerable magical power, nearly depleting his Spiritual Power.
Considering future battles, it was best to continue exploring once his Spiritual Power had recovered sufficiently.
Approximately two hours later, Sunan finished meditating.
The group continued forward.
Fear arises from the unknown.
Having learned the origins of the Iron Devourers, the group's apprehension towards these monsters diminished significantly.
Especially after having taken down five Iron Devourers in the recent battle, their morale was at an all-time high.
However, what was perplexing was that the Iron Devourers seemed to have vanished entirely, not appearing at all on their continued journey.
"Where did those monsters go?" Jordon clicked his tongue in dissatisfaction.
Kei also furrowed his brows.
If the remaining Iron Devourers were hiding, they really had no way to deal with them.
Finding a group of wall-burrowing Iron Devourers in the dimly lit, labyrinthine underground tunnels was like finding a needle in a haystack.
Sunan was contemplative.
High-level golems possess independent consciousness and AI comparable to humans, but the Iron Devourers were clearly not in this category.
They were clearly low-level golems, generally operating according to specific programming.
For instance, when encountering an overwhelming enemy, they prioritize ensuring their own safety.
This explains why successive lords have been unable to eradicate the Iron Devourers.
Faced with creatures that are 'weak against the strong' and skilled at hiding, even the most accomplished knights are at a loss.
However, just because past lords had no solution doesn't mean Sunan has none.
He closed his eyes, concentrated, and sensed the energy particles in the air.
If all goes well, these Iron Devourers should be guardians of that unknown Wizard's legacy deep within the mine.
If they find the location of the Wizard's legacy, the Iron Devourers will appear to stop them, allowing for a complete extermination.
And the location of the Wizard's legacy would have a higher concentration of energy particles than other areas.
By heading towards areas with higher concentrations of energy particles, there is a good chance of finding the target location.
Before long, Sunan opened his eyes and pointed to the tunnel entrance on the right: "Head that way."
Kei paused briefly, then immediately understood and led the way to the right without hesitation.
The group came to their senses and quickly followed.
On the way, the group moved in stops and starts.
Whenever they reached a fork, Sunan would pause to sense, then determine the direction.
They had no idea how long they had been walking when they all suddenly stopped.
This time, they hadn't encountered a monster, nor did they find another fork—rather, the road had ended.
To be precise, a dark, heavy door appeared in the middle of the tunnel.
The tightly shut door blocked off the entire tunnel.
