After returning to his immortal cave, Chen Lin summoned Yang Ziqing.
"Go and look into a woman named Ling Qianxue. She is the younger sister of Ling Qianshan, a rogue cultivator in the late Spirit Transformation realm, and is quite well known herself. But don't investigate openly. Just make some discreet inquiries, and make absolutely sure they don't discover you. Otherwise, they might kill you outright."
He briefly explained Ling Qianshan's circumstances.
For a Foundation Establishment cultivator to investigate someone close to a Spirit Transformation cultivator was extremely dangerous, so he gave careful instructions.
Yang Ziqing drew a breath and nodded. "Yes, Master. I've heard of this Ling Qianshan. He often appears at the various mission halls and is obsessed with taking missions. I'll be careful."
After Yang Ziqing left, Chen Lin began to ponder.
He carefully recalled the process of examining Ling Qianxue's soul and felt certain that he had not been mistaken. Her condition was exactly the same as Ye Luo's.
If that was indeed the case, even restoring her origin essence would not make reaching Foundation Establishment easy.
Back then, Ye Luo had only barely succeeded with Lineage Patriarch Ye personally intervening and other Void Refinement experts helping. Ling Qianxue only had an older brother in the late Spirit Transformation realm. Temporarily severing her connection to that powerful being was unlikely to be possible.
There was something else.
Ye Luo had been able to communicate with and summon the being connected to her while still in the Qi Refining stage. Ling Qianxue could probably do the same, but the siblings had concealed this fact. He had no idea what sort of monster she was connected to.
Thus, her longevity might not have come from eating some spiritual fruit at all, but from the creature connected to her.
