The aura on Yun Ling'er's body constantly increased over time. That was a natural increase after she stepped into the Three Flower at One's Prominence Realm.
Yun Ling'er's control over the aura in her body reached a point at which she materialized the Auric Flower. She could manipulate her aura out of instinct to continuously temper her body, allowing it to constantly reach new heights.
"Master!"
Yun Ling'er flew over and dove into Lu Xuan's embrace like a swallow.
Even though she had been going through private training, it did not mean that she had no sense of the outside world.
On the contrary, she had been lucid throughout the entire process. It was just that she could not afford to relax while she was condensing her Auric Flower. Therefore, she would not move even if she was facing a treacherous situation unless it directly threatened her life.
