In fact, Lin Feng had bamboozled Wang Zikai and his two friends. Their transformation wasn't simply due to Lin Feng injecting them with Inner Strength; he had also used an acupuncture technique from the Yin Yang Life Changing Needle. This activated their potential and helped them become masters of Inner Strength!
In other words, Wang Zikai and his crew were now ordinary people with the physical constitution of an Inner Strength master. Their physical conditions had significantly improved, and they possessed a faint trace of Inner Strength. However, they didn't take this seriously at all. They saw it as a ticket to further indulgence, and that was the problem.
Lin Feng was right. If they continued with this complacent attitude, their faint Inner Strength would eventually dissipate, and their physical state would return to its previous level. Even worse, their bodies might end up in even poorer condition due to their reckless lifestyle.
