Lu Zhou did not use the Birth Chart power as he flashed toward Yu Zhenghai. He discovered Yu Zhenghai's speed and movement were top-notch. For a Nine-leaf cultivator, it was very impressive.
Lu Zhou continued following Yu Zhenghai to the western palace wall. "What's he doing?"
Normally, Lu Zhou rarely paid attention to his disciples' personal lives. Perhaps, he was in a good mood today so he suddenly took an interest.
The afterglow of the evening light illuminated the stop of the wall to the tiles on the ground in the palace.
Lu Zhou had the Purple Glazed Ceramic so most cultivators would not be able to discover his presence. He leaped lightly over the wall and stood in the evening wind, stroking his beard.
Yu Zhenghai stood with his hands on his back as he looked at the evening sky, completely unaware that his master was near him.
