The technique itself was actually very simple to use. Its only requirement was for Shun Long to circulate his qi according to its method during intercourse, and his Yang essence would be automatically absorbed by Liu Mei's Yin essence, while he would also absorb her Yin essence at the same time.
The sound of Shun Long's hips meeting Liu Mei's butt, resounded throughout the room, mixed with the moans of pleasure and excitement that they were experiencing for the first time.
Suddenly, Shun Long felt his body and mind reaching the peak of their pleasure limits, before he felt a kind of warm energy leaving his body, as it slowly filled Liu Mei.
At the same time, Liu Mei felt the energy inside her body growing, as it fused with Shun Long's warm energy, growing stronger and stronger, before a similar kind of energy left Liu Mei's body, heading towards Shun Long's.
Shun Long felt his body getting rejuvenated, as Liu Mei's yin energy was fusing with his Yang.
Not only was he feeling more energetic, but he could even feel his cultivation growing, when suddenly, the energy inside Liu Mei's body had started to rapidly rise.
Less than a minute later her aura burst out of her body, before it was retracted almost immediately.
Shun Long looked at Liu Mei in disbelief, understanding that she had just broken through to the peak of rank 1 in Heaven grade almost instantly.
Shun Long could also feel himself ready to breakthrough to the Heaven grade, as a blue vortex had started to expand from his head.
Shun Long was still 'connected' physically with Liu Mei and his mind was still relishing in the pleasure of dual cultivation. The Yin Yang conjoined technique also amplified this sensation greatly.
He tried hard to clear his head, before he suppressed the vortex above his head, as he then used the energy from their dual cultivation to purify his qi balls instead.
Obviously, Shun Long didn't intend to break through to the Heaven grade before he had purified all of his balls of qi, bringing them to the same level as the 81st.
The instant that he directed his energy to his balls of qi, the 'Monarch's Hourglass' had started to circulate by itself, as the purification progress then started.
Liu Mei turned her head to look at Shun Long who seemed to be in a daze, as she asked worriedly
''Long-ge... are you okay?'' (Author's note: In this case, the -ge at the end of Shun Long's name, is another way to call someone you are close with. Calling him Shun Long isn't okay anymore as their relationship has grown, while calling someone by their full name in the Chinese culture, is the same as in the western culture where people do it if they are going to speak formally.)
Shun Long snapped out of his reverie, and looking at the naked body of the beautiful young woman in front of him, he smiled as he nodded his head, before he once again continued with their 'cultivation session'.
Two hours later, Shun Long was lying face up on the bed, while Liu Mei was now gently leaning on his side, as they had just finished another round of their arduous cultivation.
Looking at the peerlessly beautiful young woman who was lying with her head on his chest, Shun Long smiled as he gently caressed her cheek and thought to himself
''From today onwards, I will protect you no matter what happens.''
Then, seeing that the sky outside had already darkened, Shun Long suddenly remembered the contents of a golden scroll inside the 'Stone of Time', as he took it out, and looking at Liu Mei he said
''Mei'er, this is a cultivation technique that the Dao King from the 'Vermilion realm' gave to me before we left. Although I am already cultivating in another technique, this is probably better than any technique from the 'Floating cloud sect'.''
(Author's notes: Although the veterans amongst you probably know it, for those that happen to not know this, putting an <'er> at the end of someone's name is another way of endearment, while it also indicates a close relationship, usually one between confidantes, lovers, couples, or family members)
Liu Mei happily accepted Shun Long's gift, but the moment that she read the first few words, her mouth was agape as she incredulously stared at the golden scroll in her hands.
''S-aint?''
Shun Long looked at the peerlessly beautiful woman next to him, whose mind had almost blacked out, as he nodded his head and said
''Right. It is a Saint low-grade cultivation technique called the Moonlight Sigil. Don't waste any time and start training in it right away.''
Shun Long saw that Liu Mei's first reaction was to involuntarily refuse, and smiling, his hand gently touched her beautiful face as he said
''What are you hesitating for? After all, you are already my woman.''
Liu Mei nodded her head a bit embarrassed but at the same time happy by Shun Long's blunt words, before she then started to read through the golden scroll in her hands.
The more she read, the more astonished she became by this technique.
Although the Moonlight Sigil could only be practiced during the night, as a Saint low-grade cultivation technique, it was still countless times better, than the 'floating cloud sect's' Mystic low-grade 'White-cloud art', that her father and brother were cultivating.
As for herself, Liu Mei was only given a Yellow high-grade cultivation technique to train in.
It was obvious, that her actual talent in cultivation, was actually much higher than Liu Changpun's who was much older than her, but still, at the peak of rank 3 in Heaven grade.
Shun Long smiled as he saw that, Liu Mei had quickly found herself engrossed in reading the golden scroll in her hands, while he slowly stood up from the bed, and moved towards the black meditative cushion on the floor.
After sending his spiritual strength inside the 'Stone of Time', Shun Long spent the next 2 days, hastening the growth of the medicinal herbs in his herb garden.
In the meantime, although little Black still hadn't woken up from his slumber, Shun Long noticed that the dragon's body had grown noticeably bigger, almost double of its original size by now.
2 days later, as he opened his eyes, he saw that Liu Mei was now sitting on the white cushion next to him, while she was still cultivating in the Moonlight Sigil.
More than 400 spirit stones were scattered on the floor around them, filling the entire room with their pure energy.
Shun Long smiled as he saw this, before he started feeding spirit stones to the 'Heaven swallowing vine'.
Almost a week quickly passed like this, and along with the energy that he had obtained from his dual cultivation with Liu Mei, it actually took less than 7 days, for Shun Long to completely purify the 80 balls of qi above his head, finally bringing them on par with his 81st.
Seeing the 81 bright balls of qi above his head inside the 'Monarch's Hourglass', Shun Long knew, that he was now ready to try and breakthrough to the Heaven grade.
