Chapter 91: The Ancient Forbidden Spell

Following the dragon slayer through the dragon clan's underground city built of massive stone structures.

Gunie silently opened his system and entered the adventure page.

"Just as I thought!" Gunie said to himself.

Earlier, when Gunie asked the dragon slayer if there was anything good here,

he learned that there might be a dragon clan forbidden spell.

And now, the system clearly told Gunie that there indeed was a dragon clan "forbidden spell."

Adventure: Ancient Forbidden Spell.

Adventure One: Dragon Origin Magic Crystal.

Adventure Two: Ancient Altar.

Adventure Three: Dragon Fang Magic Wand.

Adventure Four: Ancient Forbidden Spell.

There were four adventures in total.

According to the pattern, the later ones were certainly more valuable.

As they moved forward, Gunie multitasked, checking the details of these four adventures.

After a thorough browse, Gunie had a general idea.

"This dragon clan underground city really has quite a few dangerous places."

"There are even many places that still harbor some kind of destructive power, as well as some dead zones."

"Once you enter these places, you basically can't get out."

"Fortunately, I have the adventure system to reasonably identify the dangerous environments in this area."

"This Dragon Origin Magic Crystal should have a similar effect to the Holy Shadow Magic Crystal I had before, making the bloodline of creatures with dragon blood more concentrated."

"Come to think of it, it's a good thing I didn't take the dragon bloodline path."

"Otherwise, meeting a dragon slayer like this, wouldn't he crush me?"

"The Ancient Altar should be similar to the one I encountered before, both having the Deep Source Anchor."

"The Daughter of the Evil God and her group... they should be heading to that place."

"Hmm, later I'll find a way to lure those two over and ambush them nearby. No matter what, we'll run into the Daughter of the Evil God and her group."

"Then there's this Dragon Fang Magic Wand and the ancient forbidden spell."

"This Dragon Fang Magic Wand is actually sealed."

"How much enmity does the dragon clan have with this Dragon Fang Magic Wand to seal away such a treasure?"

"A magic wand sealed by an entire race must be quite powerful. I wonder if it's a legendary magic wand. If so, that would be something."

"And finally, this dragon clan forbidden spell."

Looking at this powerful dragon clan forbidden spell, Gunie's mind grew slightly heavy.

"Throughout the entire continent of Oya, there are few complete forbidden spells left, and even fewer who can master them. Even among the Grandmaster level, those who can master forbidden spells are rare."

"And soon, I will possess a complete forbidden spell."

The group moved forward and soon arrived at the entrance of a resting area.

Before them lay an extremely large cross-shaped tunnel.

Stretching before Gunie and the others was a massive main passage, and on the opposite side seemed to be another dragon nest resting area.

The huge tunnel, two to three hundred meters wide, stretched endlessly to the left and right, silent and dark.

"Left or right?"

Sigurd, uncertain, asked softly.

"Left," Gunie replied decisively.

His voice was low, just enough for the two to hear.

"Why?" Sigurd whispered.

"Instinct."

Gunie answered lightly.

"Besides, my instincts are very accurate. Trust me."

Hearing this, the dragon slayer, who had been uncertain, nodded slightly.

"Then left it is."

The three then silently moved left along the massive passage.

"Of course we go left. All the treasures are on the left; there's nothing on the right," Gunie thought as they moved.

They soon passed a slightly angled cross intersection.

Both sides seemed to be resting areas.

"Keep going straight."

Before the dragon slayer could ask, Gunie spoke again.

"Mm."

The underground dragon tomb was indeed vast.

The three walked for over an hour, passing several intersections.

Along the way, they saw resting areas of various sizes belonging to dragon creatures, but now all was silent.

When they reached another cross intersection,

the ground was noticeably different from the rough terrain before.

The ground seemed paved with huge stone slabs, and these slabs appeared to have been reinforced.

"Which way now?" the dragon slayer asked softly again.

"The altar at the end of this large passage on the left should be their target," Gunie said softly.

Gunie's words made Sigurd and George's expressions shift.

Both of them looked toward the entrance of the large passage on the left.

But their vision was not as sharp as Gunie's; two or three kilometers away was already pitch black.

"Gunie, your eyesight is truly remarkable."

"It's decent," Gunie replied lightly.

Gunie's physical constitution was strong, so naturally his eyesight was excellent.

Combined with the powerful penetrating nature of source vision and night vision, the darkness had no effect on Gunie.

In this pitch-black, silent environment, Gunie's vision gave him a great advantage.

With the system's guidance, Gunie could clearly find the target.

As they cautiously moved forward, Sigurd asked in a low voice,

"Gunie, do you see anyone there?"

Gunie immediately cast an Eagle Eye spell on himself.

After carefully observing the area around the altar, he said softly,

"No sign of them. Those guys haven't arrived yet."

"But we can't guarantee complete safety. We must be wary of them already being inside and hiding to ambush us. The probability is low, but we must guard against it."

"Mm."

"Let's spread out and approach the altar from three directions to prevent anyone from lurking nearby."

"No problem."

The three then cautiously made their way toward the altar.

About half an hour later, they gathered on the massive altar, which stood about three hundred meters high.

Clearly, there were no enemies nearby.

Even though there were no enemies, the three remained hidden.

"The Deep Source Anchor."

Looking at the Deep Source Anchor formed by long chains on the altar, the dragon slayer Sigurd was inwardly astonished.

They had taken almost no detours along the way; Gunie had led them straight here.

"How is this guy's perception so terrifying? Or does Gunie have some special talent in this area?"

"But as a super spellcaster, having some peculiarities is normal."

After some thought, Sigurd set aside his doubts.

After looking around,

"It seems they haven't discovered this place yet."

The hidden dragon slayer spoke first.

"They probably don't know we're inside. For now, those guys should be searching for the Deep Source Anchor in the resting areas ahead."

"And we can use that to set up an ambush."

"Ambushing enemies—I love that," George said with a smile.

"Alright, it's settled. At the cross intersection of the passage, that's the best place to hide. And after we strike, we have plenty of open space to escape."

After some discussion, an extremely ruthless ambush plan gradually took shape.
