When Yang Wei were to learn that his own blood related family killed him in his past life, would he still go back to them?
He probably didn't know much about his origins right now from what Tian Yongheng concluded.
However, when he will come to know of them later on, there is a chance he will be swayed by familial ties and won't be able to move forward on the path to immortality.
This was why asking this question was necessary. Tian Yongheng would never accept a disciple who did not whole heartedly want to pursue a certain goal.
Yan Jingfei's goal was to protect the people around her and ascend to immortality, while Lu Qingfeng's goal was immortality as well. Liu Ruoxue's goal was to avenge her brother and become a supreme existence, while Jian Qi's goal was to reach the apex of the Sword Dao. They each had their own goals, and Tian Yongheng's existence just made it much easier for them to pursue their goals.
