A Fairy's Field in Peach Blossom Valley

A poor young man is looked down on by his village-chief father-in-law. When his attempt to borrow money fails, he's beaten to the brink of death. But at death's door, he unexpectedly inherits his ancestors' legacy. From then on, he rises like a dragon amid changing fortunes, builds wealth with his miraculous pocket dimension, stands up for the wronged with his own abilities, and practices medicine with skills that seem divine. So tell me, who else would dare compete with me!
