Those thoughts were only in Yuewu's heart; she did not say them in front of Lin Xiao.

"Senior Sister, are you sending me to cultivate at the heart of the mine vein?"

Lin Xiao was delighted. He knew exactly what the heart of a mine vein was—the core of an entire mineral vein, where the spiritual energy was the richest.

The heart of the Extreme Flame Fire Mine was where Zhou Wenqing cultivated. Under normal circumstances, she was the only one allowed to train there, and that Earth Core Lotus was also beneath the heart of the mine vein.
