Chapter 1221: Chapter 1215: Mortal Star Eradication Tribulation

The Star Core Phase, the final stage of the Mortal Realms, represents the pinnacle of the Mortal Dao's acquired powers and blessings, the totality of its potential in all four essential energies, and the gateway to a path of power beyond the limits of one's mortal birth—Mystic Ascension. 

For every cultivator born beneath the heavens, the Mortal Realms were their starting point, and they would all unquestionably face the final tribulation of the Mortal Dao if they wished to seek greater power, life, and horizons far beyond their limited vision. And for every cultivator, it all began at the Foundation Establishment Realm, the first of the three Mortal Realms. 

When a cultivator challenges this final step, the Mortal Dao reminds them of where it all began and that, should they fail, this will be where it all ends, as everything they've cultivated till now will return to its rightful owner.
