"It was a bit difficult to find the ingredients but I have procured almost everything on the list," David muttered.
"Where is it?" Alex asked, unable to contain his excitement.
"It's all in the basement."
"Lead me there quickly," Alex muttered and followed David towards the basement.
As Alex opened the door of the basement a pungent smell assaulted his senses but he ignored it and stared at the sack of bags.
The hidden science student under him was awakened wanting to get out.
On the other side, there were prices of gems of gypsum while two bags of small powder emitted a foul smell.
Alex's eyes glowed and he asked where the saltpetre was.
"There," David signalled and led him to the corner.
Alex saw pieces of saltpetre which had been mined from the limestone caves.
"Finally, I can revolutionise things," Alex muttered.
"Your Highness, what are you going to do?" David asked curiously.
