"Shadow Shift: Active Skill. Consumes 50 MP. Wraps the user in shadow energy, instantly traversing a distance equal to Spirit Attribute * 1."
Glancing at the description of Shadow Shift, Su Mu immediately spent 9 free attribute points to upgrade this mobility skill to its max level of 10.
"Shadow Shift: Active Skill, Level 10. Consumes 500 MP. Wraps the user in shadow energy, instantly traversing a distance equal to Spirit Attribute * 10."
After a series of consecutive battles, Su Mu had reached Level 30.
His current Spirit Attribute was 66.
With this stat, a Level 1 Shadow Shift allowed him to instantly cross 66 meters. At Level 10, the skill enabled him to cross an astonishing 660 meters in an instant!
660 meters.
More than half a kilometer!
Although Su Mu had only 660 MP—enough to use Shadow Shift once—in a life-threatening situation, a single Shadow Shift could send him flying 660 meters away...
This was clearly a life-saving god-tier skill!
Moreover—
Su Mu had the equipment "Rogris's Crystal Ball"!
He could store large amounts of MP in the Crystal Ball and extract it when needed to cast skills. This way, he could even cast Shadow Shift multiple times in a row!
It could be said—
With this skill, Su Mu's survivability skyrocketed manyfold!
However...
Looking at the maxed-out Shadow Shift, Su Mu hesitated slightly.
He still had 6 free attribute points.
From past experience, just 5 points were enough to evolve Shadow Shift from a normal skill into a BOSS skill.
But...
A Level 10 Shadow Shift already required 500 MP to cast. If evolved into a BOSS skill, the MP cost would likely double.
Rogris's Crystal Ball could store and extract MP, but it couldn't exceed his own MP cap.
Meaning—
If Su Mu evolved Shadow Shift into a BOSS skill now, he wouldn't have enough MP to even cast it. He'd have to wait until his Spirit Attribute increased enough to meet the skill's minimum MP requirement.
Still, it wasn't a big problem.
With Su Mu's transition to the Black Warrior class, his Spirit Attribute now grew by 50 points per level.
Even if the evolved Shadow Shift consumed several times more MP, for Su Mu now, it was just a matter of leveling up a few more times.
With that—
Su Mu, having completed his class advancement, left the area.
…
…
Time flew by.
In the blink of an eye, more than ten days had passed.
And during these ten days, the Bone Burial Ground had been anything but peaceful.
Su Mu's surprise attack had dealt a heavy blow to Death Castle.
After a furious rage, the Skeleton King pulled back all defenses around Death Castle. Not only were the Skeleton Warriors and Elite Skeletons inside the castle forbidden to leave freely, even the remaining three Bone Legions under his command were stationed directly around the castle.
This way—
If Su Mu reappeared, whether he tried to infiltrate Death Castle or ambush the stationed Bone Legions, the Skeleton King could arrive immediately to kill him!
To the Skeleton King, the recent losses weren't much.
Over its long existence, it had suffered far greater losses multiple times.
As long as the culprit was killed, it would still reign supreme over the Bone Burial Ground. With the Bone Burial Ground continuously spawning massive numbers of Skeletons, its losses could always be replenished with time.
What it didn't know was—
During these ten days of tightened defenses…
A great upheaval had occurred within the Bone Burial Ground!
Bone Burial Ground.
In a barren region more than a hundred kilometers from Death Castle, Su Mu stood quietly.
He didn't move.
But the aura around him grew ever stronger by the second.
If someone could see his attribute panel, they would find that on Su Mu's screen… endless lines of notifications were refreshing every moment!
These notifications—
All came from his Skeleton Minions killing enemies!
In the first seven days after becoming a Black Warrior, Su Mu traveled tirelessly throughout the Bone Burial Ground, doing only one thing: enslaving every Skeleton he encountered, turning them into his subordinates.
Su Mu was now a Warrior Tier.
The Black Warrior, a fusion of four different classes, required over double the EXP to level up compared to a normal Warrior Class!
Moreover—
Most of the high-tier Skeletons in Bone Burial Ground were under the Skeleton King's control.
The rest were hidden in places so secret even the Bone Legions couldn't find them.
Because of this, it was incredibly difficult for Su Mu to gain large amounts of EXP by killing high-tier Skeletons. At the very least, mass-killing them wasn't feasible.
Under these circumstances, the mid-tier and low-tier Skeletons—Elite Tier, Advanced Tier, and even Basic Tier and ordinary Skeletons—became his only viable option.
Su Mu was Level 30.
But he was a Warrior Class.
So killing Elite Tier Skeletons incurred a harsh EXP penalty.
Therefore, he chose a different path.
Corrupt Skeletons on a massive scale. Enslave as many as possible. Once he had enough Skeleton Minions, unleash them in all directions—to hunt every Skeleton in Bone Burial Ground!
Skeleton Minions killing others of the same Tier did not incur EXP penalties.
And if the Bone Burial Ground was rich in anything, it was mid- and low-tier Skeletons.
When countless Skeleton Minions spread out and hunted Skeletons across the entire Bone Burial Ground…
The EXP Su Mu received exploded wildly!
