After hearing what Lin Hao said, Wu Kui felt he couldn't even be considered an alchemy apprentice.
He had never even heard of the Snap Thousand Illusion Hand, the hand seal for controlling fire, let alone seen it.
Lin Hao had opened a door for him, a path to the pinnacle of the Alchemy Dao.
Wu Kui was reeling in shock, his mind completely captivated by the profound, inscrutable hand seal. His eyes were glued to the trajectory of the Fire Crystal Stone.
After another half hour, Wu Kui finally shifted his gaze to Lin Hao's hands.
Having grasped the trajectory of the Fire Crystal Stone, it didn't take Wu Kui long to see the hand seal on Lin Hao's fingers clearly.
But he could only just make it out, nothing more.
Wu Kui knew that this hand seal alone would be enough to keep him studying for a very, very long time.
Lin Hao concluded the technique and told Wu Kui to rest, then began to get busy himself.
