Even with a single drop of blood, I will still be invincible!

[Summoning Space Expansion]: (B) Passive skill, no level required, Summoning Space +8

Even after being upgraded to a B-rank skill, the description of [Summoning Space Expansion] remains concise and clear.

Advancing two ranks only adds eight summoning spaces.

But for Su Mubai, this improvement is far too exaggerated!

First, there's the class's Cataclysm trait, which doubles the skill effect, increasing it from +8 to +16.

Then, with the added boost of [Death Summoning], Su Mubai's summoning space limit suddenly reached an astonishing number.

[Summoning Space: 100/340]

That wasn't all. What Su Mubai cared about even more was the added catastrophe characteristic!

[Catastrophe Characteristics]:

1. The controllable range of summoned creatures has been increased to 500%.

2. After your summoned creature dies, it can be resurrected at full health in the Summoning Space. This can only be triggered once per hour for a single summoned creature.

!!!

This was the third time Su Mubai had witnessed the Cataclysmic characteristic, and the third time he had been shocked.

Both of these characteristics are simply phenomenal.

The first rule is to increase his control range over the skeletons to a radius of 500 meters.

In terms of coverage area, this is not 5 times, but 25 times!

The second characteristic is essentially an increase in the number of Su Mubai's skeleton army.

With this cataclysmic characteristic, he no longer needs to fear certain bosses' area-of-effect instant-kill skills.

Even if he kills them all in one go, he can immediately open the summoning space and replenish his troops instantly.

Unless a large number of skeletons die twice in a row within an hour, his combat effectiveness will not be affected in any way.

"The upgrade speed will be much faster now."

A hint of joy flashed in Su Mubai's eyes as he waved his wand and began summoning skeletons.

hum~

A pale gray vortex opened, and six skeleton warriors stepped out, their movements perfectly synchronized.

"Lure and kill monsters yourself, then notify me when you find humans."

Upon receiving Su Mubai's order, the soul fire in the skeleton warrior's eye sockets flickered, and he joined the monster-slaying army on the outer perimeter, carrying his greatsword.

With the increased control range, the skeleton army's movement range was greatly enhanced, and Su Mubai no longer needed to change positions for a short period of time.

After two minutes of busy work, as soon as his skill cooled down, Su Mubai waved his magic wand and summoned six high-level skeletons.

It took three consecutive uses of [Death Absorption Feedback], consuming 75 points of death energy, to fill the summoning space.

This time he didn't summon the same 4:3:3 ratio, because too many skeleton warriors would be too much for the boss to handle.

In the end, Su Mubai summoned one hundred skeleton warriors, and the remaining 240 space was evenly distributed among the skeleton archers and skeleton mages.

After the skill 【Death Absorption Feedback】 is promoted to SS level, its maximum casting range is also increased to 100 meters.

However, Su Mubai used it for 200 meters!

Even lying still, he could absorb the death energy from the corpses of monsters in the distance.

A single target can reach up to 20.

However, these ordinary monsters don't provide much death energy.

[Hint: You have successfully extracted 2 points of Death Energy from the corpses of 20 common wild monsters, "Bison".]

[Hint: You have successfully extracted 2 points of Death Energy from the corpses of 18 ordinary monsters "Bison" and 2 elite monsters "Prairie Wolves".]

……

Apart from bosses, both elite monsters and enhanced elite monsters provide the same amount of Death Points as regular monsters.

However, what's not lacking here is corpses. Su Mubai absorbs them every thirty seconds, and in less than twenty minutes, he replenishes his death energy.

Next comes the simple and tedious process of leveling up while lying down.

Every ten minutes or so, two skeletons would come and hand in items dropped by wild monsters.

Su Mubai didn't even bother to look at these trash items. He simply upgraded them all and then tossed them into his backpack to gather dust.

Based on the information in my mind, there is an auction house in the imperial city where the starting village is located.

If they are all put up for auction, it will be a considerable sum of money.

A legion of 340 skeletons, with their incredible attributes, delivered a devastating blow to the monsters on the Green Grassland.

Even the BOSS couldn't make a ripple in the face of Su Mubai's skeleton army.

[Defeating the level 10 Black Iron-tier boss "Bison Chieftain" grants an additional 50% experience bonus, totaling 1950 experience points.]

[Defeat the level 10 Bronze-tier BOSS "Prairie Wolf Leader" to receive an additional 50% experience bonus, plus 6000 experience points.]

The equipment and skill books dropped by these two bosses were quite ordinary, and they didn't drop anything that a necromancer needed.

However, one book caught Su Mubai's eye.

[Beginner Skill Book]: Increases skill points by one when used.

"Does this thing only drop from world bosses?"

After taking the beginner skill book from the skeleton archer, Su Mubai thought for a moment and understood.

If it drops from dungeon bosses, then it's worthless.

After all, there is no limit to the number of times you can run a normal difficulty dungeon; you can keep doing it repeatedly.

In that case, it won't be long before this thing becomes commonplace.

Wilderness bosses are something you can only encounter once in a lifetime.

This [Beginner Skill Book] was dropped by the Bronze-level Prairie Wolf Leader.

This grade should be the minimum requirement.

Su Mubai picked up the skill book, a thought forming in his mind.

[Catastrophe]

[Target: Beginner Skill Book]

[Hint: Please select the promotion rank: Tier 1/Tier 2/Tier 3.] (Click to view details)

Option 1: Advance to the [Intermediate Skill Book], no cost.

Option 2: Upgrade to [Advanced Skill Book], costing 2000 gold coins.

Option 3: Cataclysm to [Perfect Skill Book], consuming 1000 years of lifespan.

"Wait, does this thing consume that much energy?"

The increased cost of the [Basic Skill Book] truly surprised Su Mubai.

In particular, the [Perfect Skill Book] requires 1000 years of lifespan to obtain!

How many skill points would I need to add to offset this cost?

Although he really wanted to know, Su Mubai couldn't get promoted.

He shook his head and decisively chose to be promoted.

After confirming it, the book in my hand suddenly looked a little more refined.

You have obtained 1 "Intermediate Skill Book".

[Intermediate Skill Book]: Increases skill points by 5 after use.

After getting it for free, the effect was instantly five times greater.

The next moment, the skill book transformed into a golden light and merged into Su Mubai's brow.

[You have used "Intermediate Skill Book" x1, skill points +5, current available skill points: 6.]

Still not enough to level up [Death Absorption Feedback], Su Mubai closed the panel and continued to enjoy the thrill of rapidly increasing experience points.

But the feedback coming from his mind forced him to stand up.

A skeleton warrior sent a notification that he had seen the humans Su Mubai had mentioned.

At this stage, there shouldn't be any players coming here.

This human is very likely the appraiser from the novice village No. 9527.

"They've really gone far. What's so great about this godforsaken place for research?"

Sensing the location of the skeleton warrior, Su Mubai pursed his lips and turned to walk in that direction.

That place was almost at the very edge of his control.

After taking only a couple of steps, Su Mubai suddenly stopped, a serious expression appearing on his face.

[Notification: Your Skeleton Warrior has been defeated.]

[Note: Cataclysm has been triggered. Your Skeleton Warrior has been resurrected at full health in the Summoning Space. This Skeleton Warrior cannot be triggered again for 60 minutes.]
