Next morning,
Vishnu came out of the tent and stretched his body. It was the first time for him to experience such things but he felt his performance was not bad. He could tell from the moans of... cough cough, anyway after going on for five rounds they finally fell asleep. It was first for Jiaxin too, She gave her primal Yin to Vishnu but as they didn't dual cultivate just normal s*x no one got any benefits. It didn't matter anyway as they're both in the same realm. Dual cultivation is effective if another party is at higher realm. There are some sects that heavily promote dual cultivation though it isn't mainstream and you can't have a breakthrough just by dual cultivation.
