Hubei Provincial Museum in Central China is gearing up to market an edible version of the Sword of Goujian, one of its four major treasures, to better promote local culture, Changjiang Daily reported on Tuesday.

The bronze sword, discovered by archaeologists in 1965, was the weapon of King Goujian, who ruled the State of Yue in eastern China 2,500 years ago.

Hubei University of Technology’s School of Arts and Design has designed a chocolate Sword of Goujian, waiting to be unearthed, that it has called Xun Xun Mi Mi (discovering a secret).

The edible, white-chocolate sword is hidden beneath cocoa powder inside a box made of dark chocolate, and consumers will be asked to use small archaeological tools to open the box and discover the sword.

Hua Xue, a student at the school, spent three months on the design project.

KenGee bakery, which will make the chocolate treat in cooperation with the museum, said mass production will be possible in three months.
