"Clang, clang, clang!"
Inside the Cave Mansion, the sound of swords resonated continuously, the Golden Bamboo Sword trembled incessantly, seeming to display emotions of joy.
Eighteen lines!
Nineteen lines!
Twenty lines!
Twenty-five lines
Twenty-eight lines!
Gu Yuan's eyes were silver-white, as if countless small swords were gathering within. He sketched with his hands in the air, drawing upon the Heaven and Earth Spiritual Qi, meticulously engraving his insights on the Sword Dao onto the Golden Bamboo Sword.
The Golden Bamboo Sword shone brilliantly, vibrating continuously, its blade as thin as a cicada's wing becoming ever more dazzling, illuminating the entire Cave Mansion as if it were daylight.
"Whoosh!"
After a long while, the silver-white light in Gu Yuan's eyes gradually faded away.
The trembling of the Golden Bamboo Sword also gradually ceased.
Seeing the sword patterns, brilliant with twenty-eight lines, Gu Yuan revealed a satisfied expression.
