Just now Lin Yuan thought that Endless Summer was the top fighting force in Sky City, but now with the Sky-Swallowing Butterfly, Endless Summer can only be ranked second.

Moreover, through the blue-flashing purple butterfly, Lin Yuan can indirectly control the Killing Sky Butterfly. The Killing Sky Butterfly is equivalent to the personal force that Lin Yuan possesses.

This kind of close-range power is different from the power of a protector like the Bloodbath Mother.

Even though the Bloodbath Mother is Lin Yuan's protector, she is ultimately an external force.

And because the Slaughtering Sky Butterfly had signed a master-servant contract with the Blue-Shining Purple Butterfly, it was already equivalent to Lin Yuan's personal power.

Lin Yuan said to the blue-flashing purple butterfly.

"Little guy, it's your turn to be promoted to a fantasy species."

Upon hearing Lin Yuan's words, the blue-flashing purple butterfly flew up and immediately headed towards the butterfly-shaped will rune on Lin Yuan's other hand.

At this moment, a surge of purple energy gushed out from the body of the blue-flashing purple butterfly, revealing an elegant and luxurious aura.

The purple slowly transformed into butterfly light and shadow, as if hundreds of purple butterflies were about to fly into the sky.

These purple lights and shadows slowly gathered into a purple glow, which dyed the wings of the blue-shining purple butterfly.

This makes the purple color on the wings of the blue-flashed purple butterfly more intense and also makes the wings of the blue-flashed purple butterfly more slender.

The originally round lower half of the wings of the blue-flashed purple butterfly extended into a long tail, the end of which was emitting purple light.

Seeing this, Lin Yuan nodded secretly. It seemed that the process of the Blue Flash Purple Butterfly's advancement to the Fantasy Species was not as painful as that of Congming and Yinyin, and there were no twists and turns at all.

According to this evolutionary state, the Blue Flash Purple Butterfly should soon evolve smoothly into the Purple Beauty Butterfly.

Become the most beautiful creature among the legendary butterflies.

Just when Lin Yuan thought everything was calm, something strange happened.

Lin Yuan saw the milky blue Sky-Slaughtering Butterfly suddenly fly up from between his fingers, and carefully flew a few circles towards the blue-flashing purple butterfly that was in the process of being promoted to the fantasy species.

Lin Yuan felt admiration, hesitation, love, sadness, and determination flash across the body of the Slaughtering Sky Butterfly.

At the moment when the firm emotion appeared, the Sky-Slaying Butterfly spun lightly in the air and transformed into a gentle woman with blue hair and purple eyes.

Lin Yuan was a little confused about what the Sky-Slaying Butterfly wanted to do.

At this moment, Lin Yuan saw the woman transformed from the Sky-Slaying Butterfly looking at him with her hands clasped together, as if saying goodbye to him.

Immediately afterwards, a resolute aura burst out from the gentle woman.

A pale flame ignited on the woman's body.

Seeing this pale flame, Lin Yuan couldn't help but exclaim in horror.

"Blood sacrifice!"

"Slaughtering Sky Butterfly, you have just been promoted to the Creation Species, why would you sacrifice your bloodline for no reason?"

"Don't you want to live anymore?"

However, looking at the posture of the Slaughtering Sky Butterfly, Lin Yuan roughly understood the reason why the Slaughtering Sky Butterfly would sacrifice its bloodline.

Generally, spiritual creatures with noble bloodline inheritance have the means to sacrifice their bloodline.

Some dragon-like creatures will sacrifice their own blood when they are old and about to die, and pass the power of their blood to their most beloved offspring.

Allow the next generation to easily achieve the bloodline of the main dragon at a young age.

But sacrificing blood is a very dangerous thing, as blood is the foundation of a spiritual creature.

The origin of the bloodline spirit will be damaged if it is slightly disturbed, let alone sacrificing the bloodline.

Generally, the main dragon species spirit creatures will lose their lives directly after sacrificing their bloodline.

Only a few spiritual creatures that have stockpiled large quantities of pure spiritual materials can rely on consuming the pure elemental energy in the spiritual materials after sacrificing their bloodlines.

Regenerate the bloodline and survive for a while.

The Creation Species' Slaughtering Sky Butterfly had just transformed from a worm-eating state, which meant it had just reached adulthood.

At this time, the newly adult Slaughtering Sky Butterfly and those elderly main dragon species spirit creatures did the same thing.

He wanted to take advantage of the transformation of the Blue-Shining Purple Butterfly into a fantasy species to dedicate his own noble supreme bloodline of butterflies to the Blue-Shining Purple Butterfly to help the Blue-Shining Purple Butterfly's bloodline advance further.

The blue-flashed purple butterfly is the most beautiful butterfly creature, and its only difference is its bloodline.

Now that the Slaughtering Sky Butterfly is willing to sacrifice its own bloodline to the Blue-Shining Purple Butterfly, it is a great fortune for the Blue-Shining Purple Butterfly.

It is very likely that the Blue Flash Purple Butterfly will break through people's legendary cognition and evolve into a spiritual creature that is more beautiful than the Purple Cloud Beauty Butterfly.

Seeing the Sky-Slaying Butterfly's resolute sacrifice, Lin Yuan felt shocked.

Lin Yuan could feel the Slaughtering Sky Butterfly's deep love for the Blue-Shining Purple Butterfly, and this love was willing to turn the Slaughtering Sky Butterfly's body into ashes.

It is said that moths fly into flames, so the behavior of the Sky-eating Butterfly at this moment is no different from flying into flames.

There is no wrong version in the 1619 book forum!

Is there really love in this world where couples are willing to sacrifice themselves for the other person's fulfillment?

Of course, there is no single answer to this question for those who have been single for two lifetimes.

But the living example before him told Lin Yuan that love really overrides life in the eyes of some creatures.

The Sky-Eating Butterfly was determined to sacrifice itself, but Lin Yuan couldn't just watch it die.

The evolving Blue-Shining Purple Butterfly did not lose consciousness. It naturally felt that the Slaughtering Sky Butterfly was sacrificing itself to fulfill itself.

Lin Yuan could feel the Blue Flash Purple Butterfly's heartache and anxiety.

Even the Blue Flash Purple Butterfly wanted to interfere with evolution and stop it in order to prevent the Sky-Slaying Butterfly from sacrificing itself.

But the process of spiritual creatures being promoted to fantasy species is irreversible.

Once a spiritual creature merges with the Rune of Will, there is no turning back and it can only wait for the evolution to be completed.

Lin Yuan took a deep breath and spoke to the blue-flashing purple butterfly through his mental power.

"Leave it to me. I will save the Sky-Slaying Butterfly."

"Don't let down the ladder that the Sky-Slaying Butterfly risked its life to build for you."

After saying this, Lin Yuan activated Mobius's exclusive skill, Pure Land of Bliss, and the Pure Land of Bliss appeared directly under Lin Yuan's feet.

The pure white sand glowed with fluorescence, nourishing the Sky-Slaying Butterfly with pale flames on its body.

However, the bronze-grade, level 10 legendary quality Mobius's Pure Land cannot heal the damage caused by blood sacrifice effectively.

However, the Pure Land of Bliss can indeed provide a guarantee for the Sky-eating Butterfly.

After the Sky-Eating Butterfly sacrificed its own bloodline, it saved the Sky-Eating Butterfly's life.

Although the power rules comprehended by the slaughter worm are not attribute rules, the slaughter worm is an earth-attributed spiritual creature.

The Slaughtering Sky Butterfly that was promoted to the Creation Species still retained its original earth attribute.

Therefore, if you want the Killing Sky Butterfly to grow and restore the sacrificial bloodline, you need pure earth-attributed spiritual materials.

Lin Yuan took out handfuls of earth-attributed goddess-level elemental pearls from the Soul Locking Space and threw them at the Sky-Slaying Butterfly as if they were free.

Lin Yuan didn't care whether these earth-attributed celestial-level elemental pearls contained pearl essence, or what kind of pearl essence it contained.

At this time, saving the life of the Sky-eating Butterfly is the top priority.

The second update, and the third update will be a little later.
