Wang Xin'er, due to her cultivation level being one realm lower than her brother's, made even greater progress this time.

She directly advanced from the second layer of the Di Que Realm to the peak of the sixth layer, coming just one step short of reaching the later stages of the Di Que Realm.

Wang Yue, on the other hand, saw the greatest improvement, skipping two layers in one go from the first layer of the Tian Yuan Realm to the third layer, bringing him on par with his aunt.

Moreover, since all three of them shared close blood relations, they also gained significantly in terms of the purity of their vital energy.

Su Mengqing and Wang Xin'er both achieved a purity level fifteen times that of ordinary martial artists, which not only enhanced the power of their vital energy but also allowed them to perform four rotations of the vital energy when using certain techniques, resulting in sixteen times the original power.

Wang Yue's purity level increased from thirty times to thirty-two times, and although he was still far from being able to perform six rotations, this was merely the result of just one night of dual cultivation.

If this continued, it would likely take no more than a month for him to reach that level as well.

Unfortunately, the number of people available for dual cultivation was still limited—just his aunt, sister, Yan's mother, and auntie—so even if they each spent one night together without any other activities, Wang Yue would still not be able to do it every night.

Unless he disregarded their physical limitations and forced it, but such a thing was absolutely out of the question for him.

The next day, after spending another day fighting monsters, they set off on their return journey in the evening.

After all, the boundaries between human and beast territories were now clearly defined, and it was very difficult for human communication networks to extend beyond a hundred miles into the beast territories.

Beyond that distance, signal strength was almost non-existent, making it only possible to maintain basic calls, and beyond five hundred miles, it was even impossible to make phone calls at all.

After being away for several days in a row, their families would surely start to worry if they didn't return soon.

When they arrived in Jinling, it was already past eight in the evening.

First, they went to the Adventurers Association and asked Hong Ling and the others to go back and rest, while Su Mengqing personally drove Wang Yue and his sister home. Fate was truly mysterious in this regard.

Su Mengqing had originally intended to help bring Wang Yue and Hong Ling together while also satisfying her own desires. Still, unexpectedly, she ended up helping the siblings, while making almost no progress with Hong Ling and the other girls.

However, such things couldn't be forced; trying to push things too hard would only diminish the enjoyment. Although it was still possible to achieve the goal of dual cultivation, it would feel like doing it just for that purpose.

Now that Wang Yue and his group had killed Li Yuankui and his companions, they had inadvertently drawn the attention of his father, who was at the Gui Zhen Realm.

Time seemed to be running out.

However, before the spiritual energy began to revive, the distance between Jinling and Tianhai was not that far, but now it was actually tens of thousands of miles.

Li Yuankui and his group had used the fastest means of transportation to arrive in such a short time. Moreover, since their actions were carried out in secret, it would take some time to confirm their disappearance, and then to investigate and finally suspect or confirm that it was related to Su Mengqing—this would take at least a month.

By then, even if Wang Yue did not engage in dual cultivation with anyone else, both he and Su Mengqing would have advanced to the Gui Zhen Realm. So, upon careful consideration, time was not that urgent after all.

"Auntie, why don't you stay with me tonight?" Wang Xin'er said to Su Mengqing in the car. Their relationship was already very close, and after last night's "joint efforts," they had become even closer, no longer just an aunt and niece but good sisters who could talk about anything.

"Your brother has already swollen my pussy so much—what's the point of staying here? Are you just going to stare at his thing and get envious? It's better to go back and practice some cultivation to recover faster," Su Mengqing said, having completely let go of her inhibitions in front of the siblings.

Wang Xin'er frowned. "Me too. I guess I'll need to rest for a few days before my brother can... well, you know."

In fact, for them, a swollen pussy was not a big problem; with some effort and the use of vital energy, it would recover in no time.

What really affected them was the physical exhaustion they had experienced after being sexually active so many times that night.

Their bodies had been fully satisfied, even beyond what was normal.

Although they could continue if they wanted, it would only bring some localized stimulation and would not provide the true pleasure of both body and mind. Moreover, such behavior could harm their bodies and even damage their foundation as martial artists, greatly affecting their cultivation.

It was the same principle as for men: "A little masturbation is enjoyable, but too much can be harmful." (So, here's a piece of advice from an old fat guy: everything should be done in moderation; don't force it. And you can try it out—whether it's masturbation or something else—do it a few times a day and then take some rest. When you really need it again, the experience will be completely different.)

The car continued on its way, and the two girls continued their conversation.

"Auntie, will my breasts really grow as big as yours when I grow up?" Wang Xin'er asked enviously. "I heard that massaging them more often can make them bigger, but I don't know if it's true."

"I don't know either, but I don't think it matters much. It's related to genetics. Just like my mother and me, we were never touched by men—well, before that damn kid raped us—but our breasts were no smaller than yours, auntie," Su Mengqing said. Whether she was trying to maintain the last bit of her dignity as an auntie or not, she insisted that it was Wang Yue who raped her, regardless of his protests.

Wang Xin'er looked up in admiration. "If that's really the case, that would be great. My breasts are too small now; even my brother doesn't want to touch them."

"They will grow, and not just your breasts. Your little pussy will also become fuller and more attractive, and I bet your brother will be even more willing to touch and... well, you know," Su Mengqing comforted her.

Wang Xin'er's eyes lit up. "Really? Will my pussy also become as full as yours?"

"Of course. Maybe even more so. Then you'll surpass your auntie and become just like your mother. Your brother will definitely enjoy it even more!" Su Mengqing suddenly sighed. "It's a pity that your mother's wonderful pussy is never used... It's a real loss to the world."

"Yes, it would be great if my mother could also let my brother enjoy it. I really want her to experience that feeling too," Wang Xin'er said, her filial feelings taking an unexpected turn in this strange conversation.

Su Mengqing laughed. "Xin'er is really filial. I just wonder if your brother would be willing to use his big thing to 'serve' your mother."

"By the way, auntie, it feels like you're trying to match me up with Xin'er on purpose. Why is that?" As their conversation became more and more explicit, Wang Yue quickly changed the subject. This question had been bothering him for over two days, and he had forgotten to ask it last night, so today was the perfect opportunity.

"Isn't it because you're too good at it? Every time you do it, the other person almost dies... How could you possibly do it alone?" Su Mengqing retorted, successfully turning the tables.

Wang Yue knew that this was not the right answer.

Even if his aunt really thought she couldn't handle him alone, she could have asked Hong Ling and the others for help—especially since that was her original plan before things turned out differently.

Moreover, whether last night or now, her words always implied that she wanted to involve their mother as well, which made it even more suspicious.

However, Wang Yue also knew that if he asked any further, his aunt would not tell the truth. It would be better to find another opportunity later—maybe when she was in a state of excitement after sexual activity—then he might be able to get the truth out of her.

Fortunately, with his intervention, his aunt and sister finally moved on to another topic. Otherwise, if the conversation had continued, the consequences could have been serious: either Wang Yue's penis would have burst from overfilling, or he would have forced them to continue in the car, regardless of their physical limitations.
