Lu Yin left immediately.
Back in the cave, the old man hadn't come back yet, so he probably went out to hunt bugs. Lu Yin absorbed the free star energy, which was too rare. He unconsciously used the Heavenly Star Technique, and nine stars surrounded him.
Nine stars means nine times the speed. Even if the free stars here are rarer, they can still sweep in like a vortex, although this vortex still looks very thin.
The old man dragged the huge insect corpse towards the cave. When he noticed something was wrong, he let go of the insect body and walked into the cave. The moment he saw Lu Yin, his eyes changed, "This is the Tianxing Kung Fu?".
Lu Yin had no idea that the Heavenly Star Technique he had used to restore his strength had been discovered, and he was still absorbing star energy on his own.
