Sam didn't know, but this state was the rudimentary form of 'Martial Intent'.
The last time Sam had entered into this mysterious cultivation state, he had reached the Perfect first layer of the 'True Primal Chaos Formula'.
Afterwards, Sam had not been able to enter this cultivation state again.
However, this time, Sam had once again entered this primitive form of martial intent by relying on the effects of the high-level Soul Gathering Pellet and true essence stone combining together, as well as by spending a considerable amount of time in the ninth level of difficulty of Icy Pond Waterfall, which allowed his consciousness to expand.
Although Sam's martial intent was imperfect and it wasn't so exaggerated as the 'sudden enlightenment' described in the ancient texts, it was still able to bring great benefits to Sam. Under this kind of martial intent, his cultivation and level were rapidly rising.
