Su Atao, the most insignificant outer disciple of the Qingyun Sect, studied the "useless elixir recipe" passed down by his ancestor for three years. He finally started to make alchemy, but half of the alchemy room was blown into ruins. According to the rules of the sect, she should have been expelled from the master's sect. It happened that the palace was recruiting a royal cook, and the master slapped her on the thigh and pushed her in. He called her "dedicated to meritorious deeds and practice through experience." Su Atao looked at the smell of medicinal residue on her hands, then looked at the pots and pans in the imperial kitchen, and said, "It's not that outrageous to be employed across servers."
Unexpectedly, she failed to learn the alchemy skills, but her talent for seasoning with herbs unexpectedly awakened - licorice is better than honey for improving freshness, tangerine peel is better than wine for removing fishy smell, and even mung beans, which are used to neutralize toxicity, can make a heat-relieving soup that wowed the emperor. Just as she was gaining a foothold in the imperial dining room, she bumped into Jingan Marquis Shen Jingchen who was investigating the case incognito. This prince is known as the "cold-faced Yama of the capital", but he is always distracted by the "medicated meals" she makes. He even discovers that her "useless elixir recipe" is actually related to the "life-extension case" that shocked the government and the public that year.
One is a "good-for-nothing disciple" who blew up the alchemy furnace and switched to the kitchen, and the other is a "cold-faced prince" who investigated the case and found the imperial dining room. Starting from the relationship between "meal tickets and diners", the two got involved in the secrets of the world and the palace disputes. Su Atao relied on her unique medicinal skills to resolve the crisis, while Shen Jingchen protected her from the wind and rain. When the secret of the "useless elixir recipe" was revealed, it was discovered that the so-called alchemy technique was actually the oldest dietary wisdom. Their fate had been foreshadowed as early as three years ago when the alchemy furnace exploded.
