Bi Fang was a mythological bird!
It was recorded in Xishan Jing of Shan Hai Jing that there was a bird that looked like a crane. It was one-legged besides having red markings on green feathers and a white beak. Its name was Bi Fang, and it made a unique sound of its own. Seeing it would mean there would be fire around.
Bi Fang was an omen of fire, hence there would be great fire wherever it was.
Meanwhile, the bird before Ye Chen had fire all over its body in the form of a crow.
Ye Chen thought it was Bi Fang at first glance. He then shook his head and said, "That's not Bi Fang. It's more like a fire crow, but it doesn't look like it has materialized!"
He grabbed the fire crow before him to the bird's shock. The fire on it burned more intensely, and it charged at Ye Chen after a shriek. It even spewed fire at Ye Chen.
However, the fire did nothing to him at all.
