บท 155: Chapter 109: About to Break Through_1

In the subsequent stages of cultivation, Lin Yi found that the difficulty in upgrading to the tenth layer of Qi Refinement was twice as challenging as the ninth layer.

When cultivating at the ninth layer of Qi Refinement, one only needed to refine and compress spiritual energy, but after absorbing spiritual energy at the current stage, it first had to be compressed and refined, then further compressed for the second time to become liquefied as it moved on the path to the tenth layer.

The time it takes for this liquefaction process is almost equivalent to the total time spent rotating through the meridians accessed in the previous nine layers.

After breaking through the ninth layer, Lin Yi spent about a year and a half perfecting his skills.

Under the same circumstances, without altering his cultivation plan, he estimated that it would take him about three years to achieve full circle on the tenth layer.
