Ling Chen’s Recklessness
Normally, when undergoing a Life Transition, one usually chose a secret and safe location. Because not only the process was extremely dangerous, but it also couldn't be stopped or postponed once it started.
Furthermore, one usually would fall into an unconscious state while undergoing the Life Transition which would render one extremely vulnerable.
Undergoing a Life Transition was one of the most dangerous events or phases in the life of a warrior. Many heaven-defying geniuses and powerful experts fail to wake up from this unconscious state and stayed asleep forever in the middle of the Life Transition.
As such, people generally made an ample amount of preparation before undergoing a Life Transition as any little mistake could prove deadly.
It was also the main reason that the bronze masked man was shocked and dumbstruck after realizing that Ling Chen was undergoing his Life Transition amid a battle.
