Upon learning that Si Jingjing and Si Yingying had brought back thirteen-striped zombie crystals, these two poor Mutant were interrogated by Da Bai Tu for a long time.

They couldn't express themselves through body language, so Mu Jingjing and Mu Lingling took on the task of translating.

Everyone who understood what happened fell silent for a long time. There was only one reason: high-level zombies with more than eight slanted strokes, and even the theoretically peak thirteen-striped zombie, had truly appeared! They were in the central area of H City, and there were many of them!

As for the portal connecting the wasteland, Si Jingjing and Si Yingying didn't mention it, either deliberately concealing it or thinking it was a normal passage that didn't require special explanation.

However, Zuo Feng was also shocked by the eight-slanted-stroke Mutant. According to Si Jingjing and Si Yingying's description, the thirteen-striped zombie crystal was obtained by their companion Mutant.

As for the advancement of these two White Phoenix Beasts, Zuo Feng had guessed they might advance when they asked him for a Six-Slash Zombie, so he wasn't surprised by their advancement.

Zuo Feng frowned, unsure how to describe the misfortunes of H City.

The pathogen outbreak was already imminent, and now so many high-level zombies had appeared; it was truly one disaster after another.

However, there was still good news. Previously, Mu Jingjing and Mu Lingling had said that breaking the seal would cause a big commotion. At the time, everyone had misunderstood or not fully grasped it.

In reality, as long as the seal of the two twin Mutant wasn't broken, there would be no problem. Their companion White Phoenix Beasts, Black Dragon and White Phoenix, could be unsealed first. Not only was there no harm, but the assistance that thirteen-slanted-stroke companion Mutant could provide was immeasurable.

If an eight-slanted-stroke Mutant could kill a thirteen-striped zombie, how powerful would a thirteen-slanted-stroke companion Mutant be?

Were there any opponents left?

It's just that the zombie crystals needed for unsealing were astonishingly large. One thirteen-striped zombie crystal only unsealed the head of the White Phoenix Beast, allowing it to turn its neck, blink its eyes, and squeak. It was still far from being fully unsealed.

Calculating by this ratio, a fully unsealed companion White Phoenix Beast would require at least thirteen zombie crystals of the same level. There were a total of four here, making it an almost impossible task.

Although Zuo Feng thought it was impossible, he didn't notice that Da Bai Tu's gaze towards Si Jingjing and Si Yingying held an unusual eagerness and anticipation. Her idea was simple — to have Si Jingjing and Si Yingying find more thirteen-striped zombie crystals.

There were high-level zombies in the central area of H City, and Si Jingjing and Si Yingying could kill thirteen-striped zombies. What could be more suitable than them as working White Phoenix Beasts?

Having clarified the reason, Zuo Feng also did not intend to tell the Three Overlord Powers about the existence of high-level zombies, otherwise they would probably be scared into migrating directly.

Anyway, according to Si Jingjing and Si Yingying's description, the high-level zombies in the central area of H City would not leave the central area and currently would not pose too much of a threat.

Zuo Feng had already made a decision in his heart: as long as those high-level zombies did not actively spread, he would temporarily block the news to maintain the stability of all parties in H City.

After everything was sorted out, Zuo Feng didn't linger. He got up and left, as he still needed to check on the training progress of the group of female Super Individuals. As for the remaining tasks, such as cleaning the rooms, he believed Da Bai Tu and the other two girls would arrange them well.

After Zuo Feng left, Da Bai Tu (Yun Qianqian)'s gaze once again fell upon Si Jingjing and Si Yingying. Her scrutinizing gaze seemed to want to see through the two White Phoenix Beasts.

She slowly opened her mouth, her voice deliberately softened with coaxing, yet unable to conceal the light in her eyes:

"Si Jingjing, Si Yingying, where did you find that thirteen-striped zombie crystal? Hmm? Besides that 'big guy' you mentioned, was there anything else in that place? Or... an even bigger 'big guy'?"

Si Jingjing and Si Yingying, who were called by name, simultaneously trembled in their plump little bodies. They looked at each other and responded with squeaks.

Mu Jingjing and Mu Lingling immediately came forward, ready to translate this complex description.

"Squeak... squeak squeak... squeak!"

Mu Jingjing let out a series of urgent, faint chirps, while trying to draw a rough square outline with her small hands.

Mu Lingling, meanwhile, nodded vigorously beside her, continuously drawing the outline of a door with her small hands, while pointing to the door of Zuo Feng and the girls' bedroom.

Da Bai Tu listened carefully to the two White Phoenix Beasts' intermittent descriptions, the look of contemplation in her eyes growing deeper.

She narrowed her eyes slightly, seemingly catching an important clue.

Then she said:

"Are you saying that there's a very large door in the central area, and behind the door are many 'big guys' that produce thirteen-striped zombie crystals, and they all won't leave that place?"

Da Bai Tu's voice gradually became serious. She began to ponder, if there truly was a "crystal-producing area" where high-level zombies gathered, it would undoubtedly be the best place to obtain high-level zombie crystals.

After receiving affirmative nods from Mu Jingjing and Mu Lingling.

Da Bai Tu's pupils contracted slightly, and her usual playful smile deepened, even taking on a hint of satisfaction.

She gently stroked her chin, her gaze sweeping back and forth over Si Jingjing and Si Yingying, as if appraising two rare treasures.

"Oh? A door? An entrance with a large number of high-level zombie auras...?"

She slowly repeated, enunciating each word with extra clarity,

"So, inside... there are 'lots and lots' of these gray stones? Which are... zombie crystals?"

"Very good, very good."

Da Bai Tu's smile was dazzlingly bright. She even clapped her hands softly, producing a crisp sound that was particularly abrupt in the quiet room.

All the White Phoenix Beasts, including Zuo Feng, couldn't help but look at her.

"So, you're saying,"

Da Bai Tu leaned forward slightly, her hands clasped on her knees, smiling at Si Jingjing and Si Yingying, her tone so gentle it could drip water,

"You two little ones... not only can you enter behind that door, but you can also find and kill... hmm, 'big guys'?"

Si Jingjing and Si Yingying felt uncomfortable under her gaze. Their plump bodies stiffened, their big eyes filled with bewilderment and a hint of instinctive vigilance.

Da Bai Tu's smile grew sweeter, and her voice became even softer:

"Since you two are so capable and can enter that place... then, would you mind helping Big Sister out?"

She deliberately paused, enjoying Si Jingjing and Si Yingying's instantly stiff bodies, as well as Mu Jingjing and Mu Lingling's desperate "we're doomed" expressions, before slowly continuing:

"Go again, behind that door... just... get more high-level zombie crystals back? Not too high-level, just... like the ones you brought this time... hmm, it would be even better if they could be a little bit higher level?"

She held up two fingers, indicating a very small distance, her eyes full of encouraging "this is simple, right?" expression.

"Squeak--?!"

Si Jingjing and Si Yingying's screams rose simultaneously, their eyes full of disbelief—it was that simple!

They couldn't believe Da Bai Tu would make such a "lighthearted" request, fearing she would go back on her word, so they quickly nodded in agreement, afraid Da Bai Tu would change her mind the next second.

If they had little hands, they would definitely be patting their chests and making guarantees right now!

Da Bai Tu nodded in satisfaction, tapping her fingertips on the armrest with pleasure, as if she had only issued a trivial command.

"Such good children," she added with a saccharine smile,

"Then... let's start with two hundred? Hmm, not too many, not too few, exactly two hundred of those gray little stones."
