"What do you mean?" Su Jin-er still didn't understand. Although she admitted that having sex with Wang Yue was definitely the most comfortable and enjoyable thing in her life, she couldn't ignore everything just for the sake of comfort—they were after all mother and son.
Chu Mo, however, realized what was happening and reminded her, "Jin-er, what level of cultivation do you have right now?"
Su Jin-er was suddenly aware of this. Besides the pleasure it brought her, having sex with her brother also allowed her to rapidly improve her cultivation level. Moreover, the higher a warrior's cultivation, the longer their life would be.
If Wang Yue only had relationships with other women and never with his mother, then many years later, they might all still look young, while only Su Mengyan would die due to a lack of cultivation and thus an early end to her life. That certainly wouldn't be acceptable.
