If it weren't for the Headless demonic corpse in the underground cave, Meng Lin and the other two would have killed Qingfeng Li already. To them, Qingfeng Li was as detestable as the Headless demonic corpse.
Meng Lin's face turned green as he said angrily, "You bastard, Qingfeng Li. Why are you in the cave? And where is the spiritual root? Get out here!"
Qingfeng Li laughed as he walked out arrogantly. "You're a dumbas*, Meng Lin. You are too late; the spiritual root has already become my energy."
The reason he walked out of the cave voluntarily was to protect Mengyao Xu and Ya Yun from being disturbed during their refinement.
They would definitely get hurt if Meng Lin, the Sky Array Emperor, and the Spirit Talisman Emperor rushed into the cave.
Hence Qingfeng Li took the initiative and left the cave. He needed to deal with Meng Lin, Sky Array Emperor, and Spirit Talisman Emperor.
