Wu Ding follows Ye Fan of her own accord, while Ping Han follows Ye Fan because she admires and willingly submits to strength, whereas Ling follows Ye Fan entirely due to the force of circumstances.
When Ling saw Ye Fan, she was somewhat reluctant to approach him. In her view, she was the exalted Sect Master of Diyuan Sect, once the helm of the largest sect within the Pan Gu Secret Realm, and furthermore, she possessed cultivation at the Transcendance Tribulation Stage. How could she willingly submit to an ordinary man and become his plaything?
As Ling walked slowly towards Ye Fan step by step, Ye Fan seemed to sense her thoughts and said, "You are unwilling to become my alchemical furnace?"
Ling did not answer; she did not say yes nor no. In her heart, she had already acknowledged Ye Fan's assertion; she was indeed unwilling.
