The core area of the Skull Ruins.
Here, it was a disaster area, a level higher than the berserk area, with the lifespan depletion speed reaching a thousand times!
That meant that in this place...
Just staying here for nine hours would consume one year of lifespan.
If an ordinary human with 50 years of lifespan was placed here, they would die of lifespan depletion after half a month.
Of course.
As long as Qin Feng was in the invisible state, his lifespan depletion speed was reduced by 90%.
In other words, this disaster area with a thousand times the speed was equivalent to a berserk area with only a hundred times the speed for Qin Feng!
What's more, Qin Feng now had over six thousand years of non-tradable lifespan...
So he didn't pay any attention to this system prompt at all.
When Qin Feng jumped down the pitch-black hole and arrived at the core area of the Skull Ruins, the final challenge had already begun!
All kinds of pale skeletal monsters crawled up and drilled out from the ground around him, charging towards Qin Feng to attack.
However...
Qin Feng couldn't see these monsters with his naked eyes at all.
Because this place was pitch black, without a single ray of light!
This was the biggest difficulty of this challenge.
Here, vision was useless. One had to either rely on hearing to kill monsters or use some special means.
"To pass this challenge, a level 20 player needs at least 400 points of agility."
"The higher the player's level is, the higher the level of the monsters will be. The less noise they make when moving, and the higher the agility required to hear the monsters' movements..."
The most crucial point was that after clearing the small monsters first, the corpses of these small monsters would combine to form an Emerald-level boss, the 'Spirit of Bones'!
Only by defeating the Spirit of Bones alone could one obtain the flying mount as a reward.
In the previous life, in nine years, the total number of players who obtained this flying mount was only five...
The others either couldn't defeat it or, in the later stage, didn't think much of this flying mount anymore.
But for Qin Feng now, this was still the most reliable place to obtain a flying mount.
Of course.
Qin Feng didn't have the experience of challenging the Spirit of Bones in his previous life either. He just knew a little about it from some strategy posts on the forum...
"My current agility attribute is 653 points."
"Considering the effect of the Soul Devouring Bloodline, the agility effect is increased by 32%, which means I have 862 points of agility."
"It's already twice the minimum requirement for this challenge!"
In Qin Feng's ears, the movements of the skeletal monsters around him were really obvious.
Shadow Blade!
-278,000 (Weakness Attack)!
Shadow Blade!
-252,000 (Weakness Attack)!
...
When killing monsters in the dark, even if one could hear the target's movements, the biggest difficulty was hitting the weak points.
But for Qin Feng, he could hit the weak points with just a casual throw.
There was no way around it.
The weakness amplification effect from the Mythical-level 'Mercy Kill' was just too powerful!
Feeling that the number of skeletal monsters around was increasing, he directly used the Night Ring Blade!
In the darkness, a blade light that completely blended into the darkness spread and expanded.
-271,000 (Weakness Attack)!
-282,000 (Weakness Attack)!
-275,000 (Weakness Attack)!
...
Those skeletal monsters that surrounded him were killed in groups!
However, at the same time, there were also some skeletal archers and skeletal spellcasting creatures that directly launched various area-of-effect attacks towards the field!
Bone Arrow Rain! Bone Decay! Bone Curse!
All kinds of monster skills covered the field.
The monsters couldn't see Qin Feng either.
And when Qin Feng was in the invisible state, he didn't make any sound at all.
So, they could only release area-of-effect attacks...
Although Qin Feng could clearly hear the sound effects of those area-of-effect attacks, since he wasn't used to fighting only by hearing, he was still hit by a small number of area-of-effect attacks after all.
The field was in chaos!
In the pitch-black darkness, monsters were everywhere.
All kinds of skill sound effects and attack sound effects were heard continuously.
Fortunately, even though Qin Feng was hit by a small number of attacks, he had over ten layers of 'Black Light Shield' on him, with more than ten damage-absorbing shields, which were completely enough.
"Now my Black Light Shield has a cooldown of just over 12 seconds."
"As long as it's released, the cooldown starts counting..."
"It's very hard to deplete them all!"
With the damage being blocked by the damage-absorbing shields, Qin Feng didn't even need to use the function of 'Shadow Arc'.
He shuttled freely in the darkness and killed the skeletal monsters one by one in an instant...
The corpses of the skeletal monsters around gradually piled up.
Finally, about half an hour after Qin Feng came down.
Qin Feng's kill count of skeletal monsters reached 1,000.
He heard a huge noise coming from the darkness, and the cold ground under his feet also began to tremble.
"Here it comes."
Although he couldn't see it with his eyes.
Qin Feng clearly heard and felt that a huge monster was gathering and appearing not far from him!
All the bones in the field were linked together and jointly formed an Emerald-level boss over ten meters tall.
In the darkness, Qin Feng couldn't even see the boss's health bar.
But at the same time...
The other side couldn't see where Qin Feng was either!
If it were a normal player coming here, the boss would definitely be aware of their movements because this boss was accustomed to the darkness and was born from it.
There was a strategy post in the previous life saying that there was a special profession that once obtained the vision of the 'Spirit of Bones'. In the vision of this Emerald-level boss, as long as it was a living thing, it would appear as a green light in its eyes.
But obviously, facing Qin Feng's 21-level invisibility, the Spirit of Bones was ineffective!
Now...
"Let me see who is truly born in the darkness?"
Qin Feng held the Pale Bone Blade and the Tide-Playing Blade.
He activated the dual blades!
Towards the direction where the noise was coming from.
Shadow of Slaughter, Mercy Kill, Instant Shadow Slash!
In the extreme darkness, three shadow clones condensed and appeared.
Mercy Kill combined with Instant Shadow Slash instantly passed through the invisible boss, and a series of damage numbers of seventy to eighty thousand burst out!
But soon, Qin Feng saw a lot of 'Immune' words popping up in the darkness.
"One phase down with this wave."
"If I remember correctly, this boss has a total of four phases."
Qin Feng released the Black Light Shield, and over ten layers of damage-absorbing shields once again surrounded him.
Immediately after that, he suddenly felt a blade light swinging horizontally towards him.
Obviously, it was the Spirit of Bones, holding a white bone blade and launching a large-scale slashing attack towards the surroundings!
This skill was not mentioned in the strategy Qin Feng had read.
Maybe it wasn't even a skill.
It was just a normal attack.
The reason was that the boss couldn't see where Qin Feng was at all, so it could only adopt the way with the largest attack range.
Even if this way had the lowest damage...
As long as it could hit the target player!
But unfortunately.
The damage-absorbing shields on Qin Feng were enough for him to resist this single attack method.
The boss launched horizontal slashing attacks again and again, but Qin Feng didn't even bother to dodge and didn't receive any damage!
At the same time, one after another Shadow Blades burst out from his hands.
Seven seconds later, the three shadow clones disappeared.
The damage Qin Feng dealt was still 'Immune'.
It wasn't until more than ten seconds later that the damage numbers appeared again. Qin Feng directly released 'Shadow of Slaughter' again, followed by Mercy Kill and Scarlet Blade!
-535,000 (Weakness Attack)!
-548,000 (Weakness Attack)!
-522,000 (Weakness Attack)!
-533,000 (Weakness Attack)!
Four bright red damage numbers popped up. Immediately after that, the Spirit of Bones entered the invincible health-lock state again.
The difference was that... At this time, the boss went berserk!
On the ground of the entire cold and dark space, countless white bone blades began to stab out crazily, forming an ocean of bone spikes!
