Tangning did not know what Lan Xi had planned, but she guessed it must have something to do with Yang Jing and Luo Hao.
"After this incident, I will arrange the best manager for you, don't worry."
Tangning smiled through the entire conversation; she indeed needed a capable manager. However, Lan Xi insisted on keeping it a secret and did not organize for them to meet straight away nor did she give her a name.
In reality, Lan Xi had arranged for Tangning to appear in the show because firstly, she wanted to confirm Tangning's abilities and secondly, she wanted Yang Jing to bring her newcomers so she could see how they didn't compare to Tangning.
Of course, her plan could not be known by Tangning nor Yang Jing just yet.
