These colors clung to the-butterfly’s wings in the form of phosphorus powder. Even under the lights, the two massive wings looked both psychedelic and gorgeous.

The impossible "iridescent black" had been made manifest at that very moment!

’What a client-pleasing butterfly!’

From the Wangyu Butterfly’s current appearance, Zhong Yi could confirm its transformation, induced by the Rebirth Mushroom, had been a resounding success.

The change from four wings to two indicated that the Wangyu Butterfly had evolved from a Guardian Beast of the Brush-foot Butterfly family to one of the Phosphor Butterfly family.

The Wangyu Butterfly’s evolution was swift, but from the look on Zhong Ling’s face, it was clear the Guardian Beast had suffered immense pain as its bloodline transformed within the Death Qi.

However, this was normal!

For any Guardian Beast, every bloodline transformation was inevitably accompanied by pain.

The greater the pain, the greater the degree of the bloodline’s transformation.

Zhong Yi used All Things Exploration to inspect the Wangyu Butterfly after its bloodline transformation.

[Guardian Beast Name]: Rebirth Butterfly

[Guardian Beast Species]: Phosphor Butterfly family / Netherworld Butterfly Species

[Guardian Beast Level]: Mortal Beast Level (10/10)

[Guardian Beast Type]: Undead Element

[Guardian Beast Quality]: Bronze Quality

Skills:

[Death Speech Passage]: By vibrating its antennae, it emits a death speech capable of activating souls that have not yet dissipated within corpses, briefly consolidating them to guide the corpses in battle for itself.

Exclusive Traits:

[Wish for Rebirth]: Infuses the phosphorus powder from its wings into a target’s soul, guiding the soul to revisit its past memories. Before the soul dissipates, it can control the target, forcing it to divulge specific memories.

The Wangyu Butterfly had now evolved into the Rebirth Butterfly.

Its Skill, Death Speech Passage, had also changed due to the bloodline’s evolution.

Previously, Death Speech Passage involved emitting a death speech with its antennae to activate souls that had not yet dissipated within corpses.

It made these dead creatures rise again, becoming the Wangyu Butterfly’s puppets to fight for it.

Now, however, the Skill Death Speech Passage also had the effect of briefly consolidating souls.

Briefly consolidating the souls within the corpses would undoubtedly allow the dead bodies to unleash even greater power.

After all, when turning corpses into undead warriors, the soul is like the spark that provides Energy to the body.

Simply by first consolidating the soul and then guiding the corpse into battle, the Skill Death Speech Passage greatly enhanced the Rebirth Butterfly’s combat ability.

Zhong Yi was slightly taken aback when he saw the Rebirth Butterfly’s Exclusive Trait, Wish for Rebirth.

He couldn’t help but say to Zhong Ling,

"Xiaolingdang, your Lifebound Guardian Beast’s evolution into a Functional Guardian Beast has been a great success."

The phosphorus powder on the Rebirth Butterfly’s wings wasn’t just similar in color to the Rebirth Mushroom; its effects were also remarkably similar.

The only thing was, after being eaten by a human or a Guardian Beast, the Rebirth Mushroom could only make the target recall memories from when they were alive.

It was often used by dying spies who had returned to their organization, helping them accurately deliver their intelligence.

But the Rebirth Butterfly’s phosphorus powder could be used directly on the dead.

The phosphorus powder acts on the target’s soul, causing it to clearly recall memories from its life.

It could then control the resulting undead, making it speak whatever information one desired.

Although a soul affected by the Rebirth Butterfly’s phosphorus powder would dissipate quickly, there would certainly be enough time to extract information.

Whether in Zhong Yi’s previous world or this Guardian Beast World, prying secrets from someone’s lips and discerning the truth was always incredibly difficult.

If a key figure in an organization chose death before dishonor, they could take their secrets to the grave.

But with Zhong Ling’s Lifebound Guardian Beast, the Rebirth Butterfly, lips that remained sealed in life would be opened after death, as the deceased was turned into an undead to reveal its secrets.

The Rebirth Butterfly’s Ability was of critical importance to any faction.

A brilliant smile spread across Zhong Ling’s face upon hearing Zhong Yi’s praise.

Although Zhong Ling couldn’t yet grasp the full implications of the Rebirth Butterfly’s Exclusive Trait, Wish for Rebirth, it was obvious that the smile on Zhong Yi’s face wasn’t just to comfort her.

’As long as the Exclusive Trait the Rebirth Butterfly gained from its Quality-up was useful to Zhong Yi, that was enough!’

"Young Master, does this mean that in the future, I can use the Soul Vein Mother Butterfly to Contract not just offensive types like the Shattered Blade Butterfly and Blade Butterfly, but also some Functional Butterfly Guardian Beasts?"

"That way, could I be more useful to the team?"

"With Sister Hong Ji around, I feel like I’m not needed in combat at all."

Ever since Zhong Ling started thinking for herself, her mind had become much more active.

In Zhong Yi’s eyes, this was a good thing—a necessary quality for any excellent Guardian Beast Master.

"Xiaolingdang, the place we explored before was only a First Level Secret Realm."

"Hong Ji’s situation is unique. Just because exploring this First Level Secret Realm wasn’t difficult for us doesn’t mean all our future explorations will go so smoothly."

"You still need to focus on improving your own strength."

"The Butterfly Guardian Beasts your Soul Vein Mother Butterfly forms one-way Contracts with can be switched out at will. As the Soul Vein Mother Butterfly’s Tier increases, you can certainly Contract some Functional Butterfly Guardian Beasts."

"However, your goal in Contracting these Functional Guardian Beasts shouldn’t be for the team’s sake, but to round out your own personal combat style."

"As long as you’re strong enough yourself, you’ll be the greatest possible asset to the team."

Hearing Zhong Ling’s words, Zhong Yi knew that her current plans were focused entirely on her role within the team.
