She had been expecting a reasonable harvest when her brother said four fields of oats had been planted by the old man but what he did not mention was the impressive size of the grains. The harvest from one field was double that of two field planted with normal oats.

She had crystal water and purifying water to explain any changes in the size of plants that she planted but what excuse did the old mysterious man have? Was he a scientist or someone with a cheat of some kind? 

She looked around and tugged at Adler's hand, urging him to bend down so that she could whisper to him. 

"Brother who exactly was this man?" she asked.

Adler shrugged as response. "Why?" he asked. 

"Because these are vey good grains, they are so fat and healthy. These are good quality oats which can only be grown from extraordinary grains. As a matter of fact, if the people had known that this was food it would have been harvested a long time ago."
