After calming down, Zhang Yiyi quickly realized that she had no reason to feel wronged about losing all her Liuyun Mine resources.

The Liuyun Mine was a material necessary for refining weapons, and the severe loss to the copper mirror referred not only to the spirit of the weapon but also to the weapon body itself.

However, she never expected that such a small copper mirror could have such an insatiable appetite, swallowing all of her numerous Liuyun Mine resources without leaving a trace.

Even more surprising was that all that Liuyun Mine had come from her efforts, yet the copper mirror hadn't left her even a tiny bit of benefit. This was truly something even the most patient person couldn't tolerate!

After threatening that broken mirror for a long time with no response, Zhang Yiyi felt so frustrated that she almost lost her sanity, still holding on to the hope that this broken mirror could somehow be reasonable and have some human sensibility to spit out something for her.

"Just you wait; we'll settle this account later!"

She said this as she took a deep breath, ultimately leaving her with nothing but a vague threat.

Rather than threatening the broken mirror, it was more about comforting her own wounded feelings.

Well, here she was, back to square one after a night of turmoil—this was Zhang Yiyi's deepest realization at that moment.

Having lost so many good things was one thing, but now even all her Liuyun Mine was gone.

Zhang Yiyi wished she could drag the remnant soul from the copper mirror out and teach it a lesson, yet she was helpless against it.

Thinking about how all her valuable possessions had disappeared one by one, she forced herself to find comfort in the fact that she still had a good number of precious herbs left.

Fearing that the only valuable items she had left would also encounter misfortune, Zhang Yiyi checked several times until she was completely assured that the precious herbs were indeed still intact in her storage ring before finally letting out a sigh of relief.

"Eh, what's this?"

In her storage ring, she noticed that a silver disc about the size of her palm had appeared.

Zhang Yiyi took it out and held it in her hands to examine it carefully, finding that it was quite heavy. She almost dropped it if she hadn't paid attention.

"Is this your way of leaving me some broth?"

Zhang Yiyi held the disc in her right hand and the copper mirror in her left, instinctively questioning the copper mirror.

Aside from that, she had no way to explain where this sudden item had come from.

Moreover, she noticed that this item bore some resemblance to the material of Liuyun Mine, only much purer and better.

With a flash of inspiration, Zhang Yiyi quickly realized that the silver disc she was holding must be the essence refined by the copper mirror after it devoured all the Liuyun Kou. It seemed to be the benefit the copper mirror was finally willing to give her!

With this realization, Zhang Yiyi's mood balanced out considerably.

Although the silver disc wasn't large and she didn't quite understand its uses yet, it was definitely something extraordinary, likely worth at least as much as that huge pile of Liuyun Kou.

Hmph, at least that copper mirror still had a little awareness and hadn't forgotten to share some benefits with her.

"Sister Han, there's someone named Shi Feng looking for you."

Before long, Liu Zi came to convey the message again.

Upon hearing that Shi Feng had arrived so quickly, Zhang Yiyi hurriedly put the copper mirror away and asked Liu Zi to let him in.

Her message had barely been sent out when he arrived, indicating that Shi Feng was indeed quite anxious to find a way to treat his brother's illness.

"Brother Han... oh no, Han girl, Han girl."

Upon seeing Zhang Yiyi, Shi Feng almost stumbled over his words and stood there somewhat embarrassed.

From the young city lord, he had already learned that Little Brother Han was actually a girl disguised as a boy, so seeing Zhang Yiyi's true appearance wasn't surprising. Still, it felt a bit unusual for him.

"Big Brother Shi can call me however you're used to. It's fine," Zhang Yiyi smiled, inviting Shi Feng to take a seat without caring about the terms used for brother or sister.

"It's okay; I'll get used to it."

Although Shi Feng initially felt shy and awkward, as a cultivator, he wasn't as constrained by worldly conventions as ordinary people. He quickly relaxed and sat down with a smile.

They had shared hardships and faced life-and-death situations together. Now that the Bai family had completely collapsed, they no longer needed to be as cautious as before.

Thinking about why Zhang Yiyi had sent for him today, Shi Feng felt even happier. Sister Han had shared so much Liuyun Kou with him; once he sold it, he could buy the medicinal herb needed to cure his brother's ailment.

"Big Brother Shi, I won't beat around the bush with you. I asked you to come today to settle the earnings you left with me from the mine."

Zhang Yiyi quickly got to the point: "However, due to some reasons, I cannot give you those Liuyun Kou anymore."

As soon as these words left her mouth, the joyful expression on Shi Feng's face froze, clearly showing signs of being greatly impacted.

Although he was surprised and somewhat disappointed, he didn't feel any anger toward Zhang Yiyi.

"If you can't give it, then, well, that's that."

After a moment, he said somewhat dejectedly, clearly having accepted the outcome, even showing no intention of probing into the reasons Zhang Yiyi mentioned.

After all, in Shi Feng's view, all the Liuyun Kou originally belonged to Zhang Yiyi and her group, and had nothing to do with him, especially since his life had been saved by her.

It was a tremendous favor for her to share some with him; it was only reasonable that she wouldn't be obligated to do so, and there was no reason to demand anything.

Seeing that Shi Feng had clearly misunderstood her intention, Zhang Yiyi quickly added, "Big Brother Shi, you might not know, but the Zhu family sent people at great cost to exterminate all the mutated ants in that mine, and they've found that it has now become a barren mine. Everyone currently believes that all the Liuyun Kou there was depleted by the mutated ant swarm. If a large amount of Liuyun Kou suddenly started circulating in Jiagu Guan City, it would definitely attract investigation and trouble."

After a pause, noticing that Shi Feng showed no signs of anger or dissatisfaction, Zhang Yiyi continued, "Therefore, I don't plan to sell any Liuyun Kou here directly, nor would it be suitable to take out your share to give you. However, if you're willing, I'd like to use an equivalent amount of spirit stones or other items to replace your share. What do you think?"

"Ah... that's fine, of course!"

Shi Feng didn't expect Zhang Yiyi to mean this; he felt a wave of relief and joy, admiring Zhang Yiyi's caution and kindness even more.

"Since Big Brother Shi has no objections, then it will be easy to arrange."

Seeing this, Zhang Yiyi smiled and asked, "By the way, what specific medicinal herb does your brother need to cure his stubborn ailment? Would an equivalent amount of spirit stones be enough to buy the herb needed for your brother?"

She wasn't the type to take advantage of others, and since Shi Feng was indeed a decent person, it wouldn't hurt to lend a hand in resolving the issue he cared about most.

"That's more than enough!"

Upon hearing this, Shi Feng was even more excited and didn't bother to be polite anymore, quickly listing the names of the medicinal herbs his brother needed.

In fact, the herb he needed wasn't particularly rare; it just had a long cultivation period, which naturally made it more valuable. For many years, he had been scrimping and saving to gather spirit stones to buy this herb to treat his brother's illness.

When Zhang Yiyi heard that Shi Feng's requirements were not for particularly precious herbs, but that the several thousand-year-old medicinal herbs and treasures she possessed far surpassed their value, she quietly dismissed her original plan.

In the end, she properly converted the Liuyun Kou that should have been returned to Shi Feng into equivalent spirit stones and gave them to him, allowing him to buy the needed herbs himself, which was more appropriate.

"Sister Han's great kindness, I, Shi Feng, will forever remember it in my heart!"

Shi Feng was not someone who could navigate social situations well; when he received the spirit stones and left, he expressed nothing but sincere gratitude.

Even if he was of little influence now, one day in the future, if Zhang Yiyi needed anything, he would surely do his utmost to repay her kindness.

After sending Shi Feng off, Zhang Yiyi didn't go out for a stroll but instead spent three days in seclusion, refining her skills.

Three days later, she met up with Zheng He as scheduled to attend the auction she had heard of but hadn't had the chance to experience personally.

This time, they were not delayed by anything else; not only they, but Zhu Qing, Zhou Ren, and Zhou Yi also came. They wanted to gather together and, naturally, hoped to see if they could bid on some desired items.

With Zheng He in the group, they were respectfully invited to the VIP room on the second floor by the organizers.

A beautiful female cultivator was there to explain the basic process, rules, and several featured items of the auction to them, providing excellent service.

Of course, Zhang Yiyi was well aware that these female cultivators were catering to someone, and she casually enjoyed the high-quality spirit food and fruits while watching Zheng He occasionally basking in the attention of the beautiful women.

"Alright, alright, everyone go out; you don't need to attend to us here."

Zheng He had been enjoying the adoration of beautiful women but suddenly saw Zhang Yiyi watching like she was enjoying a show. His interest instantly waned, and he hurriedly waved his hand, shooing the several beautiful female cultivators away.

Actually, he had just let his habitual nature slip for a moment, nearly forgetting that Zhang Yiyi was still there.

Those female cultivators were certainly no comparison to Zhang Yiyi, and he didn't want to give her a reason to laugh at his poor taste, feeling inexplicably embarrassed.

The few attendant female cultivators hadn't had the chance to say more before being ruthlessly dismissed. As soon as the door closed, Zhu Qing, Zhou Ren, and Zhou Yi burst into laughter.

They were all too familiar with their boss's character; with his tail already showing, did he really think he could hide it?

"Laugh, laugh, laugh; what's so funny?"

Zheng He directly threw some spirit fruits at Zhu Qing and the others but dared not act the same way towards the equally laughing Zhang Yiyi.

"Alright, alright, we won't laugh anymore. Is that enough?"

Zhu Qing, the most obsequious among them, quickly said, "We've been to this auction more than once, so we're naturally clear on the process and rules. However, Miss Han is attending for the first time and knows nothing; I should explain it to her first."

"Go away; I can handle it!"

Zheng He wouldn't give Zhu Qing a chance to curry favor in front of Zhang Yiyi. He quickly moved over, sitting next to Zhang Yiyi to explain things to her personally.

Zhang Yiyi listened with great interest, naturally not mocking Zheng He for his unchanging nature. She also heard that the last featured item of this auction was a cave-dwelling space treasure, which made her gasp in astonishment.

No wonder it was said that this auction was the most well-regulated one in recent years; just this cave-dwelling space treasure alone was enough to warrant such a title.

Compared to ordinary storage spaces, which could only hold inanimate objects, cave-dwelling spaces could allow living beings to enter and survive. Some particularly high-level cave dwelling spaces even allowed for the planting of spiritual plants and raising of spirit beasts, providing a hiding place in times of danger, making it a special little world.

Generally speaking, there are two ways to form a cave-dwelling space: one is through a very powerful high-tier demon beast opening up its own personal space, and the other is through exceptionally rare top cultivators utilizing space stones to refine it.

Both methods are extremely rare; not all high-tier demon beasts can open personal spaces, and even if they could, the majority would rather self-destruct than leave it for humans to seize.

The second method is even more difficult, as space stones are exceedingly scarce, and genuine top cultivators capable of refining space stones into cave dwelling spaces are also rare as phoenix feathers.

Therefore, for the auction house behind Jiagu Guan City to obtain a cave-dwelling space treasure as the final featured item is a testament to the owner's capabilities.

Zhang Yiyi really didn't know if her master had ever refined a cave-dwelling space, but although she coveted today's treasure, she had no other thoughts. Just being able to broaden her horizons was already a great gain.

After all, even if she could bid on such a treasure, given her current foundational strength, she wouldn't be able to win it, let alone keep it.

Clearly, this was not only Zhang Yiyi's thinking but also Zheng He and the others.

"I heard that many masters came today, all specifically for this cave-dwelling space. The final transaction price is likely to be unimaginable."

Zhu Qing added from the side, a hint of regret flashing in his eyes; they could only look at it from a distance.

Every VIP room here has very strict security, and no matter how powerful the outside divine consciousness, it cannot penetrate inside, providing good privacy protection. That's why Zhu Qing and the others spoke without any reservations.

"Spirit stones probably won't do; the auction house for such a treasure will likely require specific treasures for trade instead."

Zheng He shared his experience, "So it's possible that this item might not sell today, or the auction house never really intended to auction such a treasure but merely brought it out as a gimmick."

"Uh... if I could just have a piece of space stone, I'd be satisfied."

Zhang Yiyi strongly agreed with Zhu Qing and Zheng He's remarks. Since she couldn't count on having a ready-made cave dwelling space, she hoped for a chance to acquire a space stone first, so she could refine it herself in the future.
