Initially, Lin Mo intended to become stronger through cultivating diligently. However, he discovered that staying idle was more comfortable. Most importantly, he could level up by doing nothing! Since he could achieve his goals by lying idle, why would he trouble himself to stand and work?

Lin Mo transmigrated to a martial arts world and realized that he had no talent in cultivating at all. Fortunately, he awakened the Idle Upgrade System. He could become stronger by staying away from the rat race and enjoying life.

Lin Mo lamented, “It’s not that I don’t want to work hard, but truly, there is no opportunity for me to do so.” As such, the most bizarre Martial Arts Saint in human history was born.
