A faint red light shot upward from the formation.
Within the formation, the dense spiritual energy surged like a rushing flood.
As Ye Chenfeng placed the last Heavenly Grade Spirit Stone, the complete Stimulating Pulse Formation instantly formed.
Fortunately, there was a barrier set up by Liu Wenquan, so the commotion here would not be discovered by others.
Ye Chenfeng, sweating profusely, looked at Wu Lingxiang and Jiang Caixuan and said, "You two sit cross-legged inside the Stimulating Pulse Formation."
Wu Lingxiang and Jiang Caixuan hesitated for a moment but then followed Ye Chenfeng's instructions.
Ye Chenfeng did not rush to proceed with the next step but rather asked, "Why did you fall prey to the Soul-Devouring Vein-severing Finger back then?"
This was a question that Old Bai and Old Hei had Ye Chenfeng ask. Although they had a rough guess in their hearts, they still wanted confirmation.
