This purple-robed cultivator was the one that had shot that blood arrow. He had rushed there before Senior White and Song Shuhang could enter the forbidden area, and prevented Song Shuhang from stepping inside.
Song Shuhang turned around to look at that purple-robed cultivator. Although the opposite party had called him by name, he didn't recognize them. Other than that, this guy was seemingly very worried that he might get in the forbidden area...
After looking at the opposite party, Song Shuhang discovered that the condition of their body was somewhat strange. He couldn't sense their true qi or spiritual qi, and was thus unable to tell their realm.
"Hehe, you finally showed yourself, eh? And here I thought you would wait for Shuhang and me to enter the forbidden area to show up," Senior White said with a calm expression on his face.
