A single insect-repelling talisman becomes a bottle of insect-repellent ester, far surpassing the world's leading standards. It can not only repel mosquitoes and bugs, but is also the top choice for a nontoxic, pollution-free pesticide! A portion of white jade salve becomes a bottle of scar-removal cream, earning the admiration of medical beauty professionals around the globe! A single message-transmitting jade slip turns into wireless communications technology... Ye Ling's hand trembled as she held the formula! Theme: Strive to reach the pinnacle of life~
