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

Epic bosses of level 180 and above are obviously not easy to find.

However, Su Mubai did not sit idly by. He simply pitched the spatial tent on Frost's back, which could only condense a layer of ice to fix the tent in place.

"Take your time looking, let me know when you find it."

Su Mubai left a message and stepped into the spatial tent.

He comfortably leaned back on the living room sofa and waved his hand to release all the Life Soul Stones.

The vast majority of them are from the top-tier Soul Stones, totaling 15396!

This was something Su Mubai deliberately left behind to enhance his soul strength.

In addition, there are 1800 intermediate-level Soul Stones dropped by the Dark Feather Vulture, and 200 advanced-level Soul Stones as a reward for the first person to solo kill a legendary-level BOSS.

It has to be said that the rewards in the game are quite stingy. The first person to solo kill a legendary BOSS only gets 200 years of lifespan, which is outrageously cheap.

However, for Su Mubai, these high-level life soul stones, once obtained for free, would grant him 20,000 years of lifespan!

However, Su Mubai is not short of lifespan for the time being, and most of the things he wants to improve require a lifespan of 100,000 years. Therefore, he wants to use these high-level life soul stones to improve other things.

Su Mubai picked up a high-grade life soul stone and had a thought.

[Catastrophe]!

[Target: High-grade Soul Stone]!

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

Option 1: Advance to [Soul Crystal], no cost.

Option 2: Upgrade to [Life Soul Essence], consuming 100 Soul Crystals.

Option 3: The cataclysm leads to the [Life Soul Source Crystal], consuming 10,000 years of lifespan.

After glancing at his current lifespan, Su Mubai's gaze sharpened, and he spoke softly:

"Cataclysmic Stage Three!"

The next moment, he suddenly felt as if he had been drained dry, as if he had been fighting a non-stop battle for several days.

[Warning: You have lost 10,000 years of your lifespan.]

[Current lifespan: Over 492 years.]

You have obtained a "Life Essence Crystal".

hum~

As soon as the system notification sounded, the "Advanced Soul Stone" in Su Mubai's hand instantly changed.

The 【Life Soul Source Crystal】 looks exactly like an infant, with a translucent purplish-black color and a faint glow. It is obviously not an ordinary item!

Just holding it in his hand gave Su Mubai a sense of comfort.

The system notification sound in his ear made him realize that this feeling was not an illusion.

[Notification: You have absorbed the energy emitted by the "Life Essence Crystal," increasing your lifespan by one day.]

Su Mubai couldn't help but sigh.

"This thing is practically a ginseng fruit from a multiverse game! Just smelling it can extend your lifespan!"

【Life Soul Source Crystal】

Exceptionally rare special treasure

Absorbing the emitted energy will increase your lifespan by one day, and after digesting it for a month, you can absorb it again.

Absorbing it will increase your lifespan by 10,000 years.

(A treasure that almost never appears in the Forbidden Lands.)

Just as Su Mubai had imagined, the [Catastrophe] was still as honest as ever, exchanging billions of years of lifespan for ten thousand years of lifespan.

The only difference is that the [Life Soul Source Crystal] can add an extra day to one's lifespan each month, and there is no loss upon death.

However, this lifespan is nothing to Su Mubai now.

What he cares more about are the additional catastrophe features.

[Cataclysmic Trait]: Significantly increases soul strength after absorption.

"It really is related to the original grade of the item!"

Su Mubai's eyes lit up when he saw the word "significant" in the description of the catastrophic characteristics.

The Cataclysm [Primary Soul Stone] adds a slight increase to soul strength among the Cataclysm traits.

Now it has directly resulted in a significant improvement!

Of course, the losses were also greater.

Previously, the loss was only 30 days of lifespan, but the Cataclysm [Advanced Life Stone] would result in a loss of a whole year.

"Compared to the strength of one's soul, what is a year's lifespan?"

Su Mubai murmured something and immediately began absorbing the energy from the [Life Soul Source Crystal].

hum~

A rich life force immediately and continuously flowed into his body, beginning to replenish the previous deficiency.

"Hmm~"

The feeling of surging vitality was still so captivating that Su Mubai couldn't help but let out a soft hum.

A lifespan of ten thousand years naturally requires a period of absorption.

It took Su Mubai a full fifteen minutes to suddenly open his eyes, a glint of light flashing deep within them.

This time, he finally felt the increase in the strength of his soul!

I don't know how to describe this feeling.

It's as if the brain was originally covered by a thin veil, but now that veil has been torn open.

Su Mubai felt his thoughts becoming clearer.

Even the ordinary system notification sounds now have a pleasant quality.

[You have absorbed a "Life Essence Crystal," increasing your lifespan by ten thousand years.]

[Current lifespan: Over 10492 years.]

"With this level of improvement, once I've absorbed all these Soul Stones and activated the [Human Butcher Domain], I definitely won't be dormant like before!"

Su Mubai stared intently at the remaining high-grade life soul stones, automatically ignoring the low-grade and mid-grade ones.

We'll deal with those low-grade items after we've absorbed the [Life Soul Source Crystal]!

Picking up another high-grade life soul stone, Su Mubai began to repeat the previous operation.

With each absorption, he could feel a significant increase in the strength of his soul.

The enhancement effect of the [Life Soul Source Crystal] is much stronger than that of 10,000 [Advanced Life Soul Stones].

Su Mubai stopped absorbing the frost's voice only when it rang in his mind, and then flashed away from the spatial tent.

"Master, we haven't found the BOSS, but there's a Dark Gold-grade treasure chest here!"
