Lin Chen had no choice but to commit suicide.
The figure that suddenly appeared was clearly a Daluo Initial Immortal; if I had fallen into his hands, wanting to die later would not be up to me.
There's no guarantee that the other party wouldn't have some miraculous technique, like the Soul-searching Technique, to extract information about my true self from my memories, so Lin Chen always chose to commit suicide as the first course of action.
Even if the other party discovered that it was just an avatar that died, it didn't matter; at least the avatar had served its purpose in luring the enemy. By the time they turned back, searching for my true self would be utterly impossible.
The Linglong Tower was the perfect place to hide.
Sect Master Shi Hongzhang, after a thorough search, could not find the whereabouts of Lin Chen and Shang Wenyin; his face turned as dark as if a storm were brewing.
