After leaving Cao Ruyan's place Elena went to meet her other friends to give them the gifts she had prepared for them.
The first person she went to was Lan Tuning. She had entered the sect alongside Lu Kao and was chosen by elder Cao Ruyan to be a potential personal disciple alongside her too. And even when Lu Kao was able to become a true personal disciple before her, she came and congratulated her like a true best friend.
Elena knew that she had some complicated feelings about Lu Kao, who was supposed to be less talented than her leaving her behind, she was able to accept it none the less. So she became one of the few lucky people who would be able to get a gift from Elena.
Obviously giving her something like the immortal pitch was out of the question. It would be equivalent to giving her poison as a gift. So Elena was going to give her that she could actually use and get stronger from that.
