STORY
I was a depressed workaday salary man. One day I was getting a bowl of ramen from my local noodle place. That's when her melodious voice drifted to my ears.

"The time has cum... an new empire rises tumescently...return to our era... the people will celebrate greatly..."
The next thing I knew I was in ancient China!?

I had no idea what was going on and started to walk. A wise old man gifted to me a fabulous scroll that revealed an ancient Way to make men virile and women swoon with excitement.
