'Breakthrough' the key?
Xue Jing's gaze shifted.
Zhu Shanying helped him voice his confusion, "Master, what is 'Breakthrough'?"
Li Qi smiled and said, "The human body has its limits, we martial artists practice body skills, and once the Skin, Flesh, Tendons, Bones, Blood—the Five Major Practices—are all completed, we are considered to have reached our own limits."
"At this stage, there is no further progress to be made. This is due to the most fundamental limit from the human body—genetic restrictions. No matter how hard one tries, at most, one could only maintain one's current strength. At times like this, one must undertake 'Breakthrough'."
"Or, to put it in terms you are more familiar with—Leaping Through the Dragon Gate."
Xue Jing sat up straight, listening carefully.
