Sister, can I be the scabbard too?

Irregular footsteps echoed through the thick, dark fog.

Besides the footsteps, there were also beast-like growls and rustling sounds, like something being dragged across the ground.

The sound grew closer and closer.

Lin Yuan unconsciously clenched his fists, tensed his body, and shielded everyone behind him.

"Student Lin."

Tang Ling'er walked to his side, reached into her skirt, and pulled out a pistol from the holster on his long leg.

"Do you know what the enemy is?"

Lin Yuan glanced at her pistol, and after confirming that it was genuine, he asked.

"have no idea."

Tang Ling'er released the safety on her pistol.

"Who exactly are you?"

"Once we survive, I will tell you everything, Lin Yuan... my lord."

"..."

Lin Yuan fell silent, and together with Tang Ling'er, they stared in the direction of the sound and footsteps.

Both of them unconsciously held their breath.

next second.

The black mist dissipated.

A pale-skinned girl in casual clothes, with silver eyelashes and hair, emerged from the mist, dragging the carcass of a lion.

"Sister, older sister?" Tang Ling'er was stunned.

"Tang Feixue?" Lin Yuan was also taken aback.

He never expected that what emerged from the fog was not a terrifying female beast, but this albino girl.

"Thank goodness, you're all alright."

Upon seeing Lin Yuan and Tang Ling'er, Tang Feixue breathed a sigh of relief and collapsed forward.

Lin Yuan reacted quickly and stepped forward to support her.

With the beauty in his arms, he realized that Tang Feixue was acting very strangely.

White scales grew on its pale skin. Its left eye remained white, but its right eye had turned pale pink.

His breathing was rapid, his pulse was erratic, and the blood vessels under his skin would bulge out from time to time.

"elder sister?"

Tang Ling'er quickly knelt down to examine her body, but upon seeing the scales, she gasped and covered her lips: "You, how did you mutate? Impossible, the apocalypse hasn't come yet..."

Upon hearing the word "apocalypse," Lin Yuan frowned: "What do you mean by 'mutation'?"

"Uh... never mind, it's come to this." Tang Ling'er gritted her teeth: "Lin Yuan, to put it simply, the end of the world will come in 27 days."

"A doomsday game will overlap with Earth."

"The mutation is a phenomenon that will occur after the apocalypse begins. Many humans and animals on Earth will be affected after the two worlds overlap, and will eventually turn into twisted monsters."

"This kind of mutation is random, just like how you and I awaken superpowers; no one knows the pattern."

It seems that Tang Ling'er doesn't know about the system and has mistaken my power for a superpower... Lin Yuan analyzed calmly.

Mutation...

The so-called mutation is essentially "possession" and "projection".

The system spoke at the opportune moment.

"I see..." Lin Yuan thought for a moment, then looked at Tang Feixue: "Do you have any way to treat this?"

"This..." Tang Ling'er lowered her head helplessly and clenched her fists.

The fingernails dug into the flesh of the palm, drawing drops of blood, yet the person remained oblivious.

Her eyes were moist, but she stubbornly refused to let the tears fall.

I had clearly made up my mind that I would never cry again in my life.

But why, why can't I help myself?

The mutation is incurable and cannot be stopped.

At least, in the apocalypse of her previous life, it was unstoppable.

Having finally been given a second chance at life,

We clearly agreed to create a future where everyone can be happy.

Why, why...

Did I influence the timeline?

Was it something I did that created a butterfly effect, causing my sister to become like this?

"Cough, cough, I, I'm fine."

Just then, Tang Feixue coughed twice and reached out her hand to Tang Ling'er.

Tang Ling'er quickly stepped forward and grasped her hand: "Sister, I, I..."

"Ling'er, cough cough, it's not your fault." Tang Feixue slowly shook her head.

Just now, she followed Lin Yuan and Tang Ling'er all the way to the zoo.

She didn't know why she came.

They've already started dating.

She definitely came at the wrong time...

He's like an idiot...

But then, something unexpected happened: a group of mysterious people dressed in purple robes appeared at the zoo entrance.

Immediately afterwards, a thick black fog enveloped the zoo.

Her special ability, the [Fallen Witch] hidden within her, also alerted her that [the Painful Dragon has begun its sacrificial ritual].

At that moment, Tang Feixue was terrified.

She wasn't afraid because of her own safety, but because of Tang Ling'er and Lin Yuan.

One was her sister, and the other was her child.

She absolutely could not stand by and watch them die.

So she made a deal with the evil witch inside her.

She gave her body in exchange for the power to save Lin Yuan and Tang Ling'er.

But now it seems...

"It seems I did something unnecessary, haha, you two are both fine."

Tang Feixue laughed.

There was not a trace of regret in her smile.

Even if she had to do it all over again—once, twice, three times… a thousand times—she would make the same decision.

Although Tang Ling'er always liked to bicker with her, she was still her younger sister.

Although Lin Yuan is an abstract concept, he is her only child in this life...

Damn it, why am I thinking about these things?

Is it a revolving lantern?

"Sister!" Tang Ling'er grasped her hand and pressed it tightly against her face. "It's alright, everything will be alright! Once we get out, I'll go find Sister Wuchang!"

"She has deciphered the sun's stone tablet and mastered some of its secrets. She can save you; she definitely can!"

Lin Yuan listened from the side, but his pupils trembled.

The Secret Technique of the Sun?

slate?

and many more……

Could it be that the University of Michigan professor I saved in my only mission... was Bai Wuchang (the White Impermanence)?

"Cough cough, it's alright, really it's alright." Tang Feixue smiled at Tang Ling'er, then looked at Lin Yuan with longing.

"However... I finally made up my mind to compete with you for once, to be the kind of older sister you want."

"That kind of... not cowardly older sister, but still... couldn't do it."

"I'm sorry, Ling'er."

"What nonsense are you talking about!"

Hearing this, Tang Ling'er completely broke down and could no longer control herself: "If you want it, I'll give it to you! You want Lord Lin Yuan? Then you can have him!"

"I... I don't mind being the cuckold! Waaah! Don't go, please, sister, don't go... I'll help you push your butt!"

"Oh, that's not allowed~" Tang Feixue also burst into tears: "After all... that's a forbidden relationship..."

Lin Yuan: ...

Why the hell do you say things like that when you're trying to get emotional?

I finally managed to get my emotions in, you bastard!

Lin Yuan looked at the two girls who were crying their eyes out, his face full of helplessness.

His helplessness stemmed not only from the abstract nature of these two extraordinary individuals.

Also because...

"Why didn't they ask me if I could save Tang Feixue?"
