Luo Mingyu advanced to the Qi Manifestation Realm during foreplay, when her Dark Phoenix Extreme Yin physique awakened. She then was able to start utilizing her Spiritual Qi Soul to chant and circulate the Dual Extremes Infinite Union Art almost immediately after, freeing up her mind to focus on the sensations and pleasure, on the act itself. Dao cultivators were naturally more proficient in using their Spiritual Qi Soul as a separate consciousness for such tasks, and she was a brilliant one so it took her almost no time to learn and use it despite only being able to conjure it for the first time since she just advanced to the realm in which it was possible to do.
As they were using the same dual cultivation technique now, the cultivation happened in the middle of the act for both. Their Yin and Yang Qi invigorated each other and facilitated each other's progress.
And we finally arrive at the part where Luo Mingyu becomes a crucial part of Wu Long's harem, as she could supercharge all of them, and allow even those with poorer talent to advance to higher realms than they would normally be able to. XD
Though her character progression is not over with this of course, as it is not over for any of them. Even Sui Luxiao, who you may possibly have reached her character progression saturation, is not even close to her full character progression. None of the characters will always stay the same as they all are evolving and changing, even if subtly. At least that is my intention. XD
Thank you for reading, commenting, and all of the tremendous support!!! XD
There is an important announcement in the auxiliary chapter
