Before advancing to the Dao Source Realm, the Silver Moon Purple Frost Blade still had some use for him.
Among the artifacts he possessed, the most precious were the Four Great Emperor Treasures, but none of them could be easily displayed in front of others. Beyond those, only the Dragon Bone Sword remained.
However, Yang Kai had already decided to find time to fuse the Dragon Bone Sword into his body, so this artifact was destined to disappear in the near future. The Silver Moon Purple Frost Blade would fill that gap perfectly. This artifact wasn't of particularly high grade, so using it wouldn't attract too much attention. What made it rare was that it could even stir a trace of the power of laws.
With this thought, Yang Kai put the Silver Moon Purple Frost Blade away without bothering to carefully refine it — no point wasting time. That way, whenever a better one came along, he could swap it out immediately.
Only then did he very solemnly retrieve the Spirit Void Jade Wall from his spatial ring.
The moment the pitch-black jade disc appeared, Yang Kai sensed how it differed from during the day. At this moment, the Spirit Void Jade Wall was actually trembling faintly, emanating waves of a profound and mysterious power. On its surface, layers of dark ripples spread outward.
The pitch-black jade disc seemed to have grown even darker, like a black hole, ready to swallow all things!
"As expected, it's reacting!" Seeing this, Yang Kai immediately understood that the reason the Spirit Void Jade Wall was changing like this was entirely because Zhang Ruoxi was nearby. When he had observed it during the day, the thing had been as still as an ancient well.
At this moment, he could clearly feel distinct spatial power undulations emanating from within the Spirit Void Jade Wall. If someone were to immerse themselves in such power fluctuations for an extended period, they might well be able to glimpse the cultivation method of spatial power.
Back when Zhang Ruoxi had stayed at the Lu residence for a month, Lu Baichuan had obtained his own opportunity within that month, gaining entry into the cultivation of spatial power.
Thinking about it now, the reason Lu Baichuan had wanted his descendant to marry Zhang Ruoxi was entirely because of the Spirit Void Jade Wall. One could even say that his deliberate efforts to deal with the Zhang family might have been related to this as well.
However, Yang Kai still couldn't use such fluctuations to discover anything. If Zhang Ruoxi were allowed to touch this jade disc, who knew what changes might occur.
It was just that although this thing was now in his hands, it had ultimately come from the Zhang family. Keeping it for himself without returning it was one thing — after all, it was his war spoil, and the Zhang family had no standing to complain. But to then go and press the Zhang family for this thing's secrets would be somewhat unreasonable.
The Zhang family members might not even know the true value of this thing! Otherwise, two hundred years ago, they wouldn't have sent it off as part of a dowry to the Lu family.
It seemed that everything still depended on himself.
Yang Kai quietly made up his mind.
Over the next two days, Yang Kai stayed at the Zhang residence without once leaving his guest room, continuously probing the secrets hidden within the Spirit Void Jade Wall. Unfortunately, he found nothing.
When he realized this approach was fruitless, he understood that remaining at the Zhang residence no longer served any purpose. He set out immediately and took his leave of the Zhang family matriarch.
The old woman and the beautiful middle-aged woman tried repeatedly to persuade him to stay. Seeing that Yang Kai was absolutely determined to leave, they didn't press further and personally escorted him out of the estate.
"Benefactor, please take care of yourself in the days ahead. If you find yourself with leisure time, do honor us with your presence at the Zhang residence — the entire Zhang family will rush to welcome you!" The old woman's complexion had improved considerably after two days of rest, but given her advanced age and the significant amount of Yuan Qi she had lost in the previous battle, a full recovery was out of the question.
Seeing her warmth, Yang Kai smiled faintly: "There will be opportunities. When the time comes, I hope the old madam won't find me a bother."
"Benefactor, this time you saved the Zhang family from crisis. We truly have no way to repay you adequately. I notice that the benefactor is alone, and daily life must be somewhat inconvenient. I would like to have Ruoxi accompany the benefactor, to take care of your daily needs in the future. I humbly ask the benefactor not to refuse!" The beautiful middle-aged woman spoke while pulling Zhang Ruoxi, who had been hiding behind her, forward.
"Huh?" Yang Kai was stunned, completely not expecting such a proposal before his departure. He instinctively looked toward the young girl.
He saw the girl with her head lowered, fidgeting with the hem of her clothes, her face flushed red, but obediently staying silent.
A strange feeling welled up in Yang Kai's heart, though he quickly understood the middle-aged woman's intention.
She clearly felt that the Zhang family was severely weakened and feared that powerful enemies might attack at any time. She wanted to cultivate a good relationship with him, making him the Zhang family's protector, with Zhang Ruoxi serving as the bridge between him and the Zhang family.
If he truly agreed, for Zhang Ruoxi's sake alone, when that time came he wouldn't stand by and do nothing.
Understanding this, Yang Kai's brow furrowed slightly. He instinctively felt some resistance, but couldn't flatly refuse.
Because according to his original plan, he intended to first handle matters with Kang Siran, and after returning to Maple Forest City, visit the Zhang family more often to thoroughly study the Spirit Void Jade Wall. Otherwise, he wouldn't have told the old woman earlier that there would be opportunities.
Who would have thought the Zhang family already intended to give Zhang Ruoxi to him?
This made him feel both resistant to such an arrangement and somewhat pleased, giving him the sensation of finding something after an exhaustive search only to discover it had been right under his nose all along.
Seeing Yang Kai's hesitation, Zhang Ruoxi seemed to grow even more flustered. The beautiful middle-aged woman smiled gently: "Although Ruoxi's cultivation isn't high and she can't help the benefactor in battle, she has good talent and a naturally serene disposition. She's clever with her hands. If the benefactor takes her along, he'll never need to worry about trivial matters and can devote himself wholeheartedly to cultivation, reaching the Dao Source Realm sooner."
The beautiful middle-aged woman vigorously promoted Zhang Ruoxi while carefully reading his expression: "I'm afraid... the benefactor might find her unworthy. If so, then let's consider that Ruoxi simply didn't have the fortune."
At these words, Zhang Ruoxi's delicate body trembled, and her small hands clenched into fists.
