The impoverished young man Chen Bing devoted himself to studying the art of ice storage, chipping ice and building cellars in the bitter winter, breaking the conventional rule that ice cannot be stored in the midsummer. He ventured into Micheng with affordable iced drinks, only to face relentless suppression from the local ice tycoon Zhao Wanshan. With the help of the healer Lin Wan'er, Chen Bing used his wisdom and integrity to defuse the crisis and break the market monopoly. Driven to a dead end, Zhao Wanshan colluded with bandits to cause chaos, coinciding with a severe heatwave emergency at the border. Chen Bing delivered ice over a thousand miles to reinforce the border, cleverly repelled the enemy, and received an award from the imperial court. He established the national ice industry chamber of commerce, set fair business rules, led the people to prosperity, upheld the great national righteousness, and ultimately became a revered Ice King of Micheng.
