After his father went missing, Ethan Chase was dispossessed and hounded for debt by the clan leader, who only assigned him the perilous Blackwind Pit. Using the "Listening Mountain Copper Whistle" left by his father, he awakens supernatural abilities, ventures deep into the sinkhole, and tames exotic beasts and unearths rare treasures through repeated life-or-death trials. He not only pays off all debts and rebuilds his home, but also exposes the schemes of corrupt merchants and foils their plot to detonate the Earth Vein. In the end, Ethan safeguards Blackwind Pit, leads Bluestone Village to escape poverty and achieve prosperity, and reunites with his long-missing father.
