Modern-day office worker Chen Nan suffers when his boss withholds his commission and an acquaintance refuses to repay a debt. By chance, he receives a gift from his ancestor in a dream: a portable storage space. He then transmigrates to an ancient era after the fall of the Great Qian Dynasty. Starting out as a prisoner, he relies on modern supplies and knowledge to establish himself in a dangerous prison camp and earns military merit through his exceptional abilities. He brings mountain bandits under his command and establishes Blackstone Camp, using advanced equipment to promote agriculture, control floods, and protect the people. Later, summoned by the imperial court, he becomes entangled in palace power struggles. Facing suspicion and deliberate obstruction, Chen Nan safeguards the capital's peace, wins the people's support, and ultimately rebuilds the dynasty, ushering in an era of peace and prosperity.
