The laws of Heaven and Earth are governed by three iron rules. The Mirror of Cause and Effect: before breaking through to a new realm, cultivators must face the Heart-Questioning Tribulation. The sins of every life they have taken will manifest as vengeful wraiths that come to claim their lives. The Yin-Yang Pact: using power beyond the Nascent Soul stage will bring down Heaven's punishment, so the most powerful cultivators often take human form and walk among mortals. The Mountains and Rivers Lock: the spiritual veins of the Nine Provinces are bound by an ancient immortal formation. The concentration of spiritual energy rises and falls like the tides, sparking the Battle for Qi every sixty years. Can Chen Qingya change this world? Will he shatter ten thousand laws with a single sword, or be lost to the darkness?
