Iris sat on her wrinkled bed, staring at the floor. It had been a week since she last saw her sisters. Because of her training, Iris could feel the Corruption Power overflowing from her body, saturating her slime, permeating the surrounding.

Her control over her power had touched the limit of the Metamorphosis Phase. She pinched her abdomen and stretched out her membrane. It expanded and moulded into another Iris, who stood motionless, smiling. The clone gently touched the original and peeled off the thin yellowish membrane.

As if undressing, the original Iris rubbed her own skin, sliding the translucent membrane off. The stuffy sensation that continuously tortured her came to an end as the cool air fell on her bouncy slime, chilling her. Though she didn't need to, she took a deep breath, enjoying the coldness which coursed inside her body.

While exploring the sensations, Iris held the membrane with which Lenmia engulfed her. Without a body to cling on, it looked like a glassy bodysuit, reflecting the light in a soft yellow glow. Iris hugged it and smelt its fragrance. Inside the thin slime, Lenmia's scent permeated the texture, seeping into Iris as she submerged herself in the wonderful aroma.

The clone Iris shook her head at the shameful yet romantic embrace.

"Original Me, everyone is waiting," the clone said. "If you want, you can ask them. No one will refuse; they will even lead you to their bedroom."

The original raised her head and gave the membrane to the clone, who accepted it and held it close to her chest.

"You too can do it," the original said. "I don't mind."

The clone shook her head, though her trembling hands betrayed her perverted desire. She tossed the membrane on the bed and walked to the window. It was shut tight, but light still seeped in, providing soft radiance for the dull room.

Because Iris hadn't moved about in the room, dust had settled on it. The clone Iris didn't like the stale air and quickly opened the window. The bright light penetrated the thick darkness and illuminated the bedroom, falling primarily onto the bed and the original Iris, who strangely glowed in multicoloured reflections.

While Iris was inside Lenmia's membrane, she noticed that the white light turned yellow before they fell on her slime, turning green after. It was an inspiration that led her to remember how light behaved. She tried to change the concentration of her slime and its colour. As she improved her control, she could shift her colour to a broader range and even condensed specific regions inside her. It was an excellent camouflage technique.

Iris looked at her green colour and nodded. The clone then looked down to her empty abdomen and placed both of her hands on it. Her membrane and the slime inside vibrated. The small mass inside it condensed and changed its shade, turning into a dark blue orb.

The original Iris stood up, walked to the clone, and slid her hand into the membrane. Both shivered, but they suppressed their excited voice. The hand grasped the orb and rubbed its sticky surface, feeling the rough form. As if it were the true core of the clone, she shivered and lost her strength. The original had to support her.

"No one would know a single difference," the original whispered. "If not for our connected mind, we could have been two Slime Girls."

"I can feel that if we reach the Transformation Phase, we'll be able to make another." The clone gripped the original's hand and held it tight. "I'm excited."

"Didn't you hate it? At least be consistent, Me."

"I don't like your shameful act, but if we all get to enjoy it, why must I refuse?"

Though they had the same mind, they still quarrelled as if they were really sisters. The original Iris wasn't going to stay still, and the clone Iris knew what she was going to do and frowned.

"I can't believe you're going to cheat," the clone said. "We never cheat, even in the original world."

The original giggled and squeezed the false core. The clone immediately placed her hand on her lips and shut it tight. Her alluring moan stuck inside her body, burning, heating. She glared at the original and tilted forward, kissing her, using her sticky tongue to ravish her inside.

The original shuddered and collapsed on the ground, taking her hand off the false core. They halted their steps, but their mind was already boiling. As they panted, the pinkish tint emerged on their membrane. The heat inside them flushed their innard, melting their form.

Their Monster Girl instinct kicked in and took over their mind. Their expression melted into an appealing gaze, a teasing smile, and a suggestive wink. As they played along, their connected mind knew that the other was already waiting.

"We've fallen too low, haven't we?" the original murmured. "Unfortunately, we can't do it right now."

The clone bit her lips but still nodded.

"I'll make sure no one notices. They will enjoy the pleasure that we can give, and with our mind connected, we'll enjoy theirs together," she said.

The original sighed and turned to the window, where a peaceful scenery laid bare. Beneath the lush green and the orderly buildings, a suppressed passion lingered all around. The message of the legacy still echoed in the wind, though everyone pretended they didn't hear it.

The words of Lilith and Gulia still whispered inside her mind. She knew her origin made her the natural enemy of the Deities. They didn't know about her existence yet, but they would eventually find out. She had to get stronger, or at least find a way to guarantee her sisters' safety.

Iris took out a silver badge. It flickered under the soft light and radiated a grand aura, which reminded Iris of its owner. Amplicia was the Ambassador of the Broken Empire, an important official that could sway the direction of The Empire. Though Iris didn't know the internal politics of The Empire, she knew that behind Amplicia was the faction of the Second Princess.

Looking at herself, Iris was already at the peak of her potential. The only way to progress further was to break the limit and reach the Transformation Phase. Though she still had one Soul Fruit, her instinct told her it wasn't enough. Her unique condition required more Corruption Power, much more than others.

The first choice was the Shadow Plane, accessible by the Shadow Heart Core. The moment she entered it, the other holders of the Fragments would come for her. Undrila was one of them, and there was no way to identify if she was a friend or a foe.

The second choice was to accumulate the Corruption Power through the Shadow Heart Core. Iris could lay low and enjoy the benefit of getting stronger little by little, but she would be tossing away her and her family's stability, clinging onto the survival of the Labyrinth and the mercy of its leaders.

Under the ordinary circumstance, Iris would have chosen the second method, but she had met with her kins and learnt of their plans and hatred. Gulia and Lilith were planning something big, and it was nearing its completion. Iris was one of the components, and she would never be able to leech the benefit without putting in work.

The moment she accepted the Shadow Heart Core, her life spun out of the peaceful world. If she wished to survive, she needed to get active and take risks. If she intended to stay away, the plan would force her with drastic measures.

"The Legacy Ground," Iris whispered. "This is an opportunity, right?"

The moment Iris reached the Labyrinth of Love, the Legacy Ground opened. Even if it weren't an arrangement, it came at the right time.

"Lilith, Gulia, I'll take this gamble." Iris closed her eyes. "Vilia, please wish me success."

With the silver badge in her hand, Iris climbed over the window and leapt out of the house. She gracefully landed on the ground and reformed into a green Slime Girl, looking slightly different than usual. After perfecting her disguise, she ran to the main street and blended in with the crowd, heading towards the Main City.

As Iris descended from her room, Reta, reading a scroll with Varda, raised her head. For an instant, the special formation she weaved quivered, sending ripples throughout the point of impact. She skillfully tugged her fingers and kneaded the strings, identifying where something passed through the barrier.

"What happened?" Varda said. "Did your formation catch something?"

"Has Sister Iris gone out of her room?" Reta abruptly stood up. "I'll go take a peek."

She took Varda's hand and pulled her towards the stair. They rushed to Iris's bedroom and knocked on it a few times. Their commotion attracted the other sisters to come out.

"Reta, why are you disturbing Sister Iris?" Varda said. "Even if she has finished her training, she will need a good rest."

"If she needs a rest, I'll be her pillow." Reta smiled. "I just can't wait to see her."

After several minutes of silence, the rest of the sisters crowded around Iris's door. The Corruption Power inside had already faded, but there was still no movement within the room. The sisters looked at one another. Something wasn't right.

Before Reta could force her way in, the door unlocked. Iris emerged out of the room. Her appearance was a mess, as though she had just suffered through a war. A hint of pink manifested throughout her membrane, filling her air with exhaustion yet indecency.

"Good morning, Sis," Iris said, her voice quivering. "I'm sorry I keep myself in the room for so long. I was just trying to break through, but it seems that I'm not there quite yet."

Pallorn grabbed Iris's arm and pulled her in. A surge of Corruption Power seeped into Iris and healed her exhaustion. Warmth circulated throughout Iris and heated her, reddening her face.

"Iris, you stay in there for too long," Pallorn said. "Everyone misses you. How are you going to compensate us?"

"I'll try my best. I have no excuse." Iris lowered her head. "I won't do this again. Can you forgive me, please?"

The sisters chuckled. The air of solemnity dispersed as a new, exciting wind took its place. The sisters bombarded Iris with so many hugs and teases that she had to retreat into her room, but they followed inside and shut the door, locking it.

"Sis, what are you doing?" Iris mumbled.

"You know what we want to do," Pallorn said. "I still haven't gotten my reward. You need to keep your promise."

"Can we not?" Iris averted her gaze. "Right now, I'm tired. I can't take more. I really can’t take it standing."

"If you can't stand, you can lie down. We'll take care of the rest, Dear."

"Please, anyone," Iris pleaded, kneeling. "Not now. Not you all."

The sisters beamed a smile as they quickly lit the candles and closed the windows. A moment later, the room became wild as faint voices echoed endlessly inside the house, lingering with a sensual fragrance that diffused from a single bedroom, where Iris tried to escape, but she kept falling deeper and deeper.
