This truly is a Core Formation Cultivator who lived to their limit and purely died of old age.
Ji Yuan's divine sense enveloped, allowing a more detailed view. The fingernails on Profound Turtle Zhenren's ten fingers had turned completely black and curved inward, with fine black lines densely covering his face.
Indeed, he looked like someone who had practiced demonic arts, and a very sinister cultivation technique at that.
Dead... truly dead.
Ji Yuan couldn't sense even the slightest trace of vitality from him; all his aura had completely vanished, his flesh and divine soul extinguished, having reached their limits.
When their group approached closer, it wasn't just Ji Yuan; Phoenix Peach and Yun Qianzai also sensed it with their divine sense.
The two simultaneously looked at Ran Kui, who nodded in response.
"Indeed, he has already entered parinirvana."
"If that's the case, then let Profound Turtle Zhenren return."
