What was Feng Wu doing?
She was racking her brain with a big frown on her face.
What could it be?
Feng Wu narrowed her eyes, kept her gaze straight forward, and remained motionless.
Just then, an idea seemed to strike her for a brief moment, but it flashed by so fast that by the time Feng Wu realized it, it was gone.
Feng Wu tried very hard to think, but she just couldn't recall it.
Thump, thump, thump —
Just then, they heard the loud noise of a beating heart.
"What's that?"
They turned in the direction of the sound and saw a red heart behind them.
It was only the size of a baby's fist, but the sound it made was very loud.
"Where did that heart come from? Was it there before?"
"Listen. It's beating forcibly."
"Hey, don't you think that it's expanding?"
"It is! It was only the size of a baby's fist just then, but it's the size of an adult fist now."
"And it's growing as we speak!"
