"Donghai Yin Jiao Wood?" Bai Ruozhu had never heard of it before.
"It's said to be a type of tree that only grows in the darkest depths at the bottom of the Donghai. They also say Yin Jiao Wood is guarded by flood dragons, so it's extremely rare. But it's not afraid of seawater—soaking in the sea for ten thousand years won't rot it, so you can imagine how valuable it is. This door actually used so much Yin Jiao Wood, that's really something," Jiang Yichun said.
Bai Ruozhu looked up at the top of the door. It really was enormous.
"Does Danliang have this Donghai Yin Jiao Wood?" she asked.
Jiang Yichun shook his head. "Not sure, I've never seen it."
"Then how can you be sure it's Donghai Yin Jiao Wood?" Bai Ruozhu was intrigued.
Jiang Yichun's expression shifted, his brows knitting tightly. "I don't know. What I just said isn't something I knew before. It just suddenly popped into my head, and I inexplicably recognized the material of this door."
