"I have only just arrived. This is my first time doing this," Han Sen said.
"You'll need to put your back into it and work hard. There may be no guards here, but you have a quota of ten walnut powder sacks a day. If you don't meet that quota, they'll bump you back down a level. Then, you'll have to do the test all over again," the man explained.
"What use is the powder for?" Han Sen asked, as he began to work.
"Those of us down here don't have a clue. But it's a material that's wanted by the big cheese, and since we're required to produce it, we don't question it any further." The man briefly paused, look around, and then spoke again in a quieter tone. "You didn't hear this from me, got it? But... rumors say that Immortal Emperor, the big boss of this place, uses it to craft what has been dubbed Immortal Pills."
"What are they for? Do they make him immortal?" Han Sen inquisitively asked.
