A powerful force tried to pull Lee off from his footing, but his strength kept him stable. Lee was astonished, as he saw a series of runes lighting up on the step, only to fade away after half a second.
Lee saw runes for the first time after arriving at Utopia. He knew about the existence of runes, which are the Mana counterpart of Qi talismans, from D's narrations and mentions.
At a glance, the runes looked like meaningless pencil strokes that, when combined, make an almost intelligible form. Some had dots accompanying the strokes, while some looked like completely random strokes of brush.
Lee remembered that a chapter in the Encyclopaedia To Greatness was wholly about runes. According to the book, rune strikes and symbols were part of an organised set called Runera. This set of alphabets consists of more than 1700 individual symbols which convey distinct meanings. When combined, they form spells and chants which are activated with Mana.
