Once the Mana Obstrusion was completed, Siderius moved on to the important thing, the enhancement of the salt.
Siderius placed a pouch of pure white salt onto the ground. This was not salt he gained from Jude but salt he had purified himself. Then he placed the two jugs of blood and urine on either side.
Period blood of a virgin woman contained pure negative energy of the living. The urine of a virgin man contained the pure positive energy of the living.
There were cases when virgin urine was used to repulse evil spirits back in the day, when the alchemy of Siderius' old world was still very underdeveloped. But soon, with time and alchemical advancement, people knew that it wasn't the urine that was effective, it was the positive energy inside it, or more precisely, the Proton Energy.
