Just like that, after an unknown amount of time, a current of air pushed them away from the starry sky and landed them on the dark and deep ground of the spiritual world.

The Whale of the Void Sky was lying not far away at this moment. This was the depths of the spiritual world. Apart from the weird ones, basically no living creatures would pass by here. It did not have to worry about crushing those creatures which were no more than microorganisms in its eyes, and could land on the ground at will.

As for the weird thing that was crushed, well, it couldn’t be crushed to death, so it was just a good opportunity to tickle it.

Estelle landed on the ground and looked back at the endless, pitch-black wall behind her, which shone like black crystal. She asked Eros curiously:

"What's this?"

Eros glanced at his mother's expression and said with a nonchalant air:

"One eye of the Sky Whale."

As expected, after these words were spoken, Estelle's face showed shock again.

She kept looking back at the endless wall, muttering in disbelief:

"It's just an eye?"

"How big is it!"

Seeing the shock on his mother's face, Eros felt a sense of satisfaction.

He summoned the Sky Whale through the contract, wasn't it just because he wanted to see his mother's frightened expression?

Listening to his mother's dreamlike mumbling, Eros chuckled and said:

"I don't know the exact size, but it won't be much smaller than the sun we see every day."

Estelle blinked again when she heard this: "Is the sun very big?"

Barbara sneered in Eros' soul space.

Eros then realized that the astronomy of this world was locked, and the sun they saw every day was not the real sun at all, but the projection of the sun's authority on the sky.

To put it simply, it's similar to a sticker.

Eros, realizing he had made a fool of himself, coughed lightly and changed his words:

"In short, the length of this Void Sky Whale is no less than one million kilometers."

At this point, Eros changed the subject and said, "Okay, okay, let's not talk about this anymore. Let's start preparing for the promotion ceremony."

Seeing Eros talking about business, Estelle suppressed her amazement at the length of the Sky Whale and her expression became serious.

Eros snapped his fingers and summoned several skeleton guards, instructing them to dig a pit at regular intervals to bury the soul crystals of the wronged souls.

It didn't take long before all forty ghost crystals were buried according to the pattern.

After everything was ready, Eros took out a bottle of Sequence 4 finished potion from his body and handed it to his mother.

Looking at the blue liquid rippling in the crystal bottle in her hand, Estelle felt nervous for no reason.

Promotions to low-sequence levels are fraught with risk, let alone advancement from low-sequence to mid-sequence.

That is undoubtedly a greater risk. If you are not careful, you will be affected by the power of the potion and eventually lose control and turn into a monster.

Fortunately, because of the protection of the Lord Spirit of the Weapon, she does not have to worry about being attacked by strange things during her promotion, which makes her promotion success rate much higher than those of ordinary warlocks.

Suppressing the sudden nervousness in her heart, Estelle let out a long sigh, looked at her child, and said in a serious tone:

"I'm ready to start."

Eros nodded, looking at his mother with eyes full of encouragement, as if coaxing a child:

"Mom, I'm sure you can do it."

Hearing this, the suppressed tension in Estelle's heart disappeared without a trace in an instant, and she gave Eros a cold look.

This poor child, is he the mother, or am I the mother?

Not wanting to pay any attention to the troublesome child, Estelle took the bottle of potion in her hand and sat down in the center of the ritual formation.

She looked down at the potion in her hand, took a deep breath, pulled out the cork, and drank it in one gulp.

As a salty liquid slid down her throat, a surge of spiritual power erupted from her body.

Estelle quickly focused her mind and tried to control the power.

During this period, her body continued to expand, and silver scales grew from her exposed legs, soon covering her entire legs.

At the same time, illusory spiritual tentacles continued to emerge from her body.

These tentacles pulled at her body, gradually turning her body into an indescribable twisted object.

Just as her body was about to turn into a pile of wriggling tentacles, beams of blue light emanated from the crystals of the wronged souls buried underground.

These pillars of light penetrated the soil that buried them and extended towards the sky of the spiritual world.

Just after these beams of light appeared, Estelle, who was about to turn into a pile of wriggling tentacles, suddenly stopped deforming and gradually began to return to human form.

These pillars of light acted as anchors, awakening her consciousness from the crazed spirituality contained within the potion, reminding her that she was a human being, not a monster.

After regaining her human form, her body continued to expand, and her legs gradually transformed into a silver snake tail. Two bulges began to grow on her white and smooth back, and then a pair of white wings slowly grew out of the bulges.

Seeing his mother break free from the crazy spirituality contained in the potion, Eros breathed a sigh of relief, knowing that his mother had survived the initial danger of the promotion ceremony.

He was ready to deprive his mother of her soul at any time through the power of souls.
