Wu Long helped Hua Ziyan clean up, as well as remove any traces of their "testing" from the product. They would of course buy it anyway but in order for Hua Ziyan to not feel too embarrassed Wu Long made sure that there was no evidence of just how exciting their shopping was this time.
As they made their purchases they went out of the shop, her face flushed red. But since the shop attendants saw Wu Long whispering to her from time to time they assumed that their exciting night ahead was what made her blush so much and they smiled at the cute couple.
When they came back Wu Long led her to his room and they went to sleep together, as she cuddled into his embrace. He did not advance since his foundation started to show slight signs of instability after continuous breakthroughs, instead cultivating the Spiritual Qi War Art.
Hua Ziyan, on the other hand, made a significant advancement reaching the 7th level of the Revolving Qi Realm.
