Time, invisible and intangible, more elusive than space, yet omnipresent and inescapable.
Even for those in the Great Emperor Realm, there comes a day when their lifespan is exhausted, even the exalted gods face decay and decline, no one can achieve eternal life, escape the grasp of time.
People strive to cultivate and seek strength merely for their ambition; some for money, some for power, others for desire, but immortality is not the pursuit of martial artists.
Yet everyone hopes to gain a bit more, hence they seek higher realms and longer lifespans, thus the perception of Time Laws becomes particularly important.
Only by perceiving Time Laws and mastering the force of time, can one break through to the Saint Realm.
As for the Great Emperor Realm, it involves fusing the power of time with spatial force, transforming into the even more powerful force of space-time.
