The best way to wake up had always been naturally, by the course of the normal biological clock, or in some other pleasant ways. Certainly being hit in the face and stomach by punches weren't examples of such.
Hence, when Yang felt himself being beaten to pulp and was dragged out of the dream land, he was in a pretty bad mood. However his temper soon dispersed when he saw the cause of it.
"Don't! Please stop!" Yin was once again shouted in distress. Unlike before though, she had a bit more mobility.
"Yin! Wake up!" The Fire God quickly urged her, while throwing away the pelts. He then firming grabbed her wrists to prevent her from hurting him and herself.
"Stop! Let me go!"
"Yin! It's just a bad dream."
As she kept screaming and fought like it was a live-or-die situation, Yang found it harder and harder to limit her movements. When he saw something glistering running down her cheeks, he decided to change tactic.
He thought of how his mother used to calm him down during the occasions when he was sick or in pain. She would then sing lullabies, which always worked on him.
He choice one of his favorites and smiled slightly as he sang gently.
"Sleep little willow
It's still winter
Still asleep are birch and heather
Rose and hyacinths
It's still a long time until spring
Before rowan is flowering
Sleep little willow
It's still winter"
When he was done with the first verse, he noticed that she was relaxing. He thus released her and placed her slowly on the ground, before continuing.
"Sunshine's eye is watching you
Sunshine's arms rock you
The forest's path will soon be green
And every flower will bloom
Yet a little sunshine prayer
Little willow becomes so green
Sunshine's eye sees you
Sunshine's arms rock you."
As he witnessed the miraculous effect of his action, he kept choosing different soothing songs to vocalize. He kept singing even when his throat felt drier than this desert.
Eventually, he had to stop and moisturize his vocal bands. He sat down with one of his knees flexed and rested his elbow on it. Then he grabbed a water bag and drank slowly, while observing the sleeping woman.
She was very peaceful at the moment. He suspected that she had a fever again but not as severe as the day before.
The sun was ascending and it was getting hotter. Therefore Yang didn't bother to cover them anymore.
After a while, Yin finally woke up.
The lullaby does actually exist, although not in English. Guess the original language. (^÷^)
