To protect her sister's orphan, Xu Qinghuan cut ties with her greedy relatives and left on a rainy night carrying fifty thousand yuan and the child. Fortunately, a warning from the child helped them escape a bridge collapse disaster. She leased an abandoned, withered pond, unexpectedly dug up an underground sweet spring, and successively discovered rare wild fish populations. Facing schemes from relatives and layers of suppression from capital competitors, she joined hands with the retired Lu Xingye to stay true to their original intentions and break through numerous business conspiracies. Relying on unique cold spring resources to build a business and achieve prosperity, she resolved a flash flood crisis to preserve the entire village, and ultimately achieved soaring career success, harvested a fulfilling romance, and completed her self-counterattack.
