Upon entering 1403, Xiao Jin immediately smelled a strange odor permeating the surroundings, a mixture of rotting flesh and disinfectant.

The curtains were torn into strips and wrapped around the window frame, and gauze stained with black blood was scattered on the ground.

Yin Xin's bedroom door was locked, but Xiao Jin broke it open in no time.

The flavor inside is stronger.

As soon as Xiao Jin entered, she saw the woman lying on the bed. Her left cheek still retained the beauty of a young girl, but her right cheek had rotted to the bone.

The exposed chest cavity seemed to reveal beating lung lobes, and black spores were scattered with each breath.

"These long crystal clusters started appearing on A-Xin's body three days ago." Yin Hang knelt by the bed and gently removed the gauze from his sister's neck.

Xiao Jin looked closely and saw purple crystals piercing out of her trachea like coral, sending chills down her spine.

She said...it didn't hurt, and then locked herself in her room.

Xiao Jin glanced at Yin Hang indifferently: "She won't let you in, so you really won't go in? No, you want to die with your sister, don't you!"

Yin Hang lowered his head in shame.

Xiao Jin then took out the [Purification Serum] from his spatial storage; the pale purple liquid refracted a strange halo on the tube wall.

"This is!" Yin Hang looked at Xiao Jin in confusion, but Xiao Jin did not explain.

Bending down, she precisely inserted the needle tip into Yin Xin's carotid artery.

The moment the liquid was injected, Yin Xin's rotting half of her face suddenly twitched, and a purple crystalline film formed on the ulcerated area at a speed visible to the naked eye.

Yin Hang's heart was pounding in his throat. Just as he was about to reach out, he noticed that the black threads began to flow in the opposite direction, gradually turning from liquid into gas and dissipating into the air.

"It's changed, it's changed!" Yin Hang exclaimed, pointing to a patch of Yin Xin's restored skin.

She really has a way!

Xiao Jin straightened up, looked at Yin Xin whose breathing had become much more stable, and nodded knowingly.

This [Purifying Serum] really works not only for players, but also for NPCs.

"Bang!"

Xiao Jin turned her head and was suddenly surprised to find Yin Hang kneeling in front of her, the sound of his knees hitting the ground clearly audible.

His face was filled with such sorrow that it was almost overflowing; tears streamed down his face like a broken string of pearls.

Yin Hang clenched his fists so tightly his knuckles turned white: "I beg you, please save my sister! If you can save her, my life is yours from now on!"

Yin Hang's voice was choked with sobs, each word sounding like it was being torn from the depths of his heart, filled with helplessness and pleading.

Xiao Jin frowned slightly, her gaze as cold as ice, calm and resolute: "I won't take your life, and your life is useless to me."

Her voice was cold and clear, like a winter wind, making one shiver.

Upon hearing this, Yin Hang trembled violently, as if all his strength had been drained away.

He knelt on the ground, his hands hanging limply at his sides, tears still streaming down his face, but he could no longer make a sound, only gasping for breath, his chest heaving violently.

Xiao Jin looked at him, a complex emotion flashing in her eyes, but she quickly regained her composure.

"It's not that I don't want to save them, it's just that I have very little of that serum left."

Upon hearing this, a glimmer of hope flashed in Yin Hang's eyes. He eagerly raised his head, his gaze fixed on Xiao Jin's face.

"I didn't mean anything by it, I just want to save my sister. Please tell me, where does the serum come from?" His voice trembled, afraid of hearing an answer he didn't want to hear.

It wasn't something that needed to be kept secret, so Xiao Jin naturally wouldn't go on and on about it.

She slowly began, "Although it's a bit bizarre, you've played monster-hunting games, right? The serum drops from killing Fog Demons."

Yin Hang stared wide-eyed, his face filled with disbelief.

No wonder...no wonder those serums were so precious. A surge of intense despair welled up inside him, as if the whole world had collapsed at that moment.

As for whether Xiao Jin might be lying to him, Yin Hang never even considered that, because Xiao Jin had no reason to lie to him!

Moreover, after what has happened these past few days, Yin Hang has realized that Xiao Jin is actually cold on the outside but warm on the inside.

Furthermore, there has been no news from the government, let alone any development of a cure. The fact that Xiao Jin could produce the 'serum' at this point clearly shows that it appeared out of thin air.

Glancing at his younger sister lying on the bed, Yin Hang bit his lip until it bled.

A resolute glint flashed in his eyes!

kill!

So what if it's a Fog Demon!

He was going to die anyway, but he took the gamble. He'll go kill the Fog Demon and find the serum in a little while.

But Yin Hang never expected that Xiao Jin seemed to have seen through his thoughts, and then said something that plunged him into the abyss.

"Don't get too excited yet." Xiao Jin looked at the thick fog outside the window: "Ordinary fog ghosts don't drop serum. Only special vengeful ghosts do, but they are often stronger than ordinary fog ghosts."

You're not coming back!

Xiao Jin's definition of "strong" is still based on the strength of the players being compared.

Yin Hang had no way to kill the special fog demon.

"No..." Yin Hang clenched his fists tightly, crescent-shaped bloodstains appearing on his palms: "I must go."

He looked up, and the emotion in his eyes almost burned Xiao Jin.

The two looked at each other and fell silent for a moment.

After a moment, Xiao Jin sighed and said, "Wait for me at the door at eight o'clock tomorrow morning." Then Xiao Jin left.

Yin Hang stood there stunned for a moment, his mind blank, but then he was overjoyed.

"She...she wanted to help me, right?"

At this moment, Xiao Jin, who had already left 1403, walked slowly down the corridor, a rare look of embarrassment on her face.

I acted impulsively and ended up taking on a troublesome task for myself.

Leading a group to kill the Mist Demons is not as fast as her coming alone!

Moreover, it's still unclear whether we can find any trace of the special fog ghosts. Xiao Jin was afraid that giving Yin Hang hope would only lead to despair.

"Sigh~" Xiao Jin sighed deeply.

Who told that guy to show that look he knew so well!

In my previous life, I was just as fearless when facing high-level zombies.

As soon as Xiao Jin Gang came out, several figures quickly hid in the shadows, drawn by Yin Hang's cries.

Xiao Jin collected her thoughts and pretended not to see it.

These people really have so much free time!

The next second, a system notification sound suddenly rang out:

[Gene evolution tree activated: Atomization (Basic)]

The hidden creature on his wrist suddenly arched its back, as if its fur had been bristled. It hissed as it peered out at the churning wall of fog to the south.

A tremendous roar could be faintly heard coming from there.

"Hmm? A gene evolution tree!" Xiao Jin raised his eyes and paused in his steps.

"Whose evolution? Human genes, or tree genes?" Xiao Jin leaned towards the former.

Perhaps that's the root cause of the poisonous fog.
