Talking about this, Jiang Yichun's heart ached again; he had brought ruin upon Ruozhu.
"Don't dwell on it too much, I've found the reason." Bai Ruozhu was somewhat excited. "Think carefully, did you ever get your blood on this tree when you were here before?"
She was referring to the black Curse Tree.
Jiang Yichun was a bit dazed, and after a long pause, his expression suddenly changed, "I remember once I flicked blood away, it might have got on that tree, back then the evil energy in me wasn't purged yet."
Why did he remember it so clearly? Because he was wearing specially tailored armor at that time, and due to someone else, he had a nosebleed.
