In the midsummer of the 13th year of Zhenguan of the Tang Dynasty, in the bustling city of Chang'an, a Yunqi Restaurant with unique decoration and novel style became famous. The owner of the restaurant, Lu Heng, is very clever. His original dishes, exquisite furnishings, and secret ice-making methods that are rare in summer have attracted guests from all over the city to visit.
One day, a murder occurred in the restaurant. A wealthy businessman who was doing business died inexplicably. During the dinner, the servants accompanying him insisted that the restaurant deliberately poisoned people. Faced with an unprovoked disaster, Lu Heng calmly and calmly investigated the scene. With the help of subtle traces such as the strange smell on the deceased's fingertips, he deduced and verified layer by layer, and finally exposed the self-directed poisoning and frame-up conspiracy of the wealthy businessman, and took advantage of the situation to involve the secretly opposing Wenyage forces.
Lu Heng accidentally discovered that the director of Wenya Pavilion was secretly colluding with others and was suspected of reselling prohibited weapons. Before the storm was over, an assassin sneaked into the restaurant late at night and waited for an opportunity to attack. Fortunately, the guards fought hard to repel the assassins.
In order to resolve the crisis and stabilize the business, Lu Heng took advantage of the situation and launched an exclusive guest policy to attract customers, and at the same time exposed the truth about the poor quality of Wen Yage's ingredients. After several battles, Yunqi Restaurant not only failed to be defeated by malicious suppression, but its reputation became more and more famous, with an endless stream of diners coming and going.
