Chen Xiao, a geology major, helped his childhood friend Ai Beisen through thick and thin, going to the mining area in Lan Country to pick raw stones and making the Jubao Rough Stone Store net millions in profit, only to receive a mere 10,000 yuan in wages at the end of the year. Completely disillusioned, he chose to leave and accidentally awakened the perspective ability in his left eye. Using the remaining 40,000 yuan, Chen Xiao bought a neglected black Wusha stone, cutting out a high-ice-variety spring-and-coulour jadeite in one stroke, thus beginning his path of picking up bargains and cheating through life. Facing Ai Beisen's blacklisting, framing, and malicious revenge, he always stuck to his bottom line of integrity, gradually gaining recognition from jewelry giants. In contrast, Ai Beisen sold fake goods, took out high-interest loans, and recklessly gambled on the king of stones, ultimately losing all his luxury cars, real estate, and face.
