"Actually… cultivation level-wise, at least a small proportion of Year 2 students are more advanced than Feng Wu." Xuan Yi paused for a while after those words, before he went on, "But, they may not be able to pass the sixth floor."
Feng Xun nodded. "I see that now. Little Feng Wu could have defeated the robot much sooner on the fourth floor, but she prolonged the fight to study its structure!"
Xuan Yi nodded. "Because the robot on the fourth floor is the smallest and the weakest one."
Feng Xun said, "That was why she seized the opportunity to explore the robot and figure out its pattern of movements."
Xuan Yi said, "Indeed. And she was still doing it on the fifth floor."
Feng Xun said, "Without the experience from the previous two floors, she would never have been able to succeed on the sixth floor, because it's several times more difficult than the previous floors put together."
