As time passes, he can feel the trial has more advantages than he throught, but at the same time, he was certain that once he attained the 16th stage combat power, it was impossible to improve any further.
The reason for this was actually simple, his body might not be able to withstand it. The 16th stage was already on another dimension all together. Being able to barely achieve it was already admirable, after all it was a mortal wilding power of immortals.
The difference was vast, and the life index associated with it was also on a whole new level, and to the outsiders, it was impossible to have a higher life index even after attaining such combat power.
