Xian Yu, after a few days, quietly returned to his residence. In the hall, he found the two sisters enjoying their meal.
"Xiao Jiao Jiao, have you felt uncomfortable these past few days?"
Seeing Xian Yu suddenly appear, the two sisters were quite pleased.
"I'm fine! Thanks for caring, Brother Yu. It just feels a bit chilly, a little strange."
Feeling a cool sensation in their bodies seemed normal to Xian Yu, given the influence of the demon god's power. Fortunately, they detected it in time and prevented it from getting worse.
Though he thought it was unlikely for any issues to arise, Xian Yu still examined them carefully and sensed with precision.
In his perception, there was indeed a slight increase in the chill on Zhang Yujiao, but there were no other anomalies.
Xian Yu speculated that defeating the will of "Lu Bei" in the past few days might have caused an imbalance in the marks on Zhang Yujiao's head. The current situation seemed like an outbreak, and it would likely subside after some time.
During this period, Xian Yu would have the Cryo Crystal Butterfly absorb the power as much as possible. Missing this opportunity might mean waiting for it to happen again, and who knew when that would be.
"It's okay; your condition isn't severe. Just avoid going out in the wind and rain for a while, and it'll get better. Besides, the beautiful butterfly on your head can speed up your recovery. Don't worry too much."
Zhang Yujiao, upon hearing this, had crescent-shaped eyes that seemed even happier.
"Brother Yu, where did you... get this butterfly? It's so beautiful! When sister is better, can you let me see it?"
"I originally wanted Grandpa to take us to catch one, but I heard these special butterflies are hard to catch, and even if caught, they disappear. I've always wondered why," added Zhang Lingmei, her younger sister. Seeing the butterfly on her sister's head, she did like it.
She knew the butterfly belonged to Brother Yu, and it was used to help her sister recover, so she had been well-behaved and hadn't asked before. However, hearing Xian Yu's words now, it seemed that her sister's "illness" would be better in a few days, so could she borrow it from Brother Yu for a couple of days?
Xian Yu, upon hearing this, just smiled faintly. He understood the little girl's thoughts: either showing off to other kids or wanting the same treatment as her sister.
"This butterfly isn't that fun to play with, but when your sister gets better, I'll let you play with it for a couple of days."
"But you can't let others touch it. If you can manage that, I'll agree to let you take it out," he added.
Xian Yu's butterfly was different from others. Due to Xian Yu's influence, the Cryo Crystal Butterfly wouldn't attack the sisters, but for others, it was hard to say. After continuously absorbing power during this period, its control over power had been effectively trained. However, it didn't mean it would allow others to touch it. If instinctively provoked, it would respond with either death or injury.
Although Zhang Lingmei didn't understand the reasons behind it, she happily agreed.
"I know! Don't worry, I won't let anyone touch the little butterfly."
"I promise!"
Xian Yu, upon hearing this, didn't say anything more. He just patted the heads of the two little girls, gave a glance to the Cryo Crystal Butterfly, and then returned to his room.
The poor Cryo Crystal Butterfly, a majestic being comparable to an Elemental Lord, was casually treated as a pet by Xian Yu, to be taken out for others to show off.
However, at this moment, it continued to absorb power diligently from Zhang Yujiao's head, unable to voice any protests.
Back in his room, Xian Yu didn't immediately start cultivating but took out the crystal instead.
Even though he hadn't figured out its purpose these past few days, just looking at it gave Xian Yu a peculiar sensation. His control over elemental power had become more adept.
In the past, his utilization of elemental power was rather shallow, limited to simple attacks like ice spikes or arrows, or utilizing the inherent properties of the elements. This approach worked against opponents weaker than him, but when facing stronger adversaries, he needed to employ other means.
Now, however, he could alter the structure of the formed elements, making them more robust and frigid. While he couldn't create extravagant attacks yet, the enhancements were notable.
This was just from observation. If he could fully understand the crystal's function, the benefits would be even greater!
Unfortunately, Xian Yu tried various methods but couldn't succeed in understanding the crystal's purpose.
However, there was still a partial solution – letting the Cryo Crystal Butterfly absorb it. If the butterfly could absorb the mark of the Frost Demon, it should be able to absorb the crystal's power too.
Yet, Xian Yu was reluctant at the moment. He still wanted to comprehend more about the use of elemental power. Moreover, for the current Cryo Crystal Butterfly, even if it could absorb the crystal's power, it would be a slow process similar to the first absorption of the Frigid Heart Core.
Instead of that, Xian Yu decided to use it himself for now, saving the possibility of letting the Cryo Crystal Butterfly benefit from it in the future.
...
Time flowed like water, and days passed by.
During this time, Xian Yu lived a calm life. Aside from people trying to get close to him, everything else was fine. There was a maid who gave him a letter to deliver, thinking of throwing it away. However, considering it was sent by uncle Zhang, it implied a connection to Xian Yu's past.
Curious, he opened the letter.
It was an invitation from a woman named Qing Xue to meet at the Luliting.
Seeing the signature, Xian Yu took a moment to remember. It was the lady from the tea house on the rock that night. He vaguely recalled her mentioning the surname Qing. At that time, he was preoccupied with Uncle Zhang's urgency and didn't pay much attention.
Now, seeing the signature, he recalled her name.
However, Xian Yu didn't have the time or inclination to indulge in old acquaintances.
If he were to go, he could predict what would happen next. Probably, they would talk about his relationship with the Li family, then dive into various connections, and eventually, there would be a flood of proposals for cooperation.
Xian Yu wasn't particularly interested in those matters; strengthening himself was far more reassuring.
So, of course, he pretends not to have seen the invitation. As for what the other party might think, it's not his concern.
Another day begins with the sweet melody of birds
and the fragrance of flowers. Xian Yu casually checks the sign-in interface and notices that the "Basic Sword Technique" has lit up. This implies he can enhance it.
He won't wait to accumulate it and then use the "Breathing Technique." Waiting for several years is not an option. After all, who relies on someone with only 160 game stones?
"Time flies. It's been quite a few days."
He upgrades the sword technique and receives information. Closing and opening his eyes, there's no qualitative change in the technique, just as he expected.
"It seems I have to wait until swordsmanship reaches level four. I wonder what changes will occur at that time. Looking forward to it..."
