Mandra was a powerful drug. It was experimented from the mandrake plant.
Although its short-term use would refresh the mind and enhance physical strength, but its long-term use would cause addiction, and over time would make people insane, and also cause dementia.
It was common practice for the lords and honorables of the previous empire to consume five vial of Mandra, which also aggravated the demise of the previous empire to a certain extent.
It was precisely because of the lessons learned from the past that in the Arthurian empire, Mandra was a drug that was banned from circulation.
But now that banned drugs have been found in the inner courtyard of the deep palace. How could Lordking not be ridiculed?
