...
The refining of the "Invisible Sword" took much longer than expected.
Lin Li let out a long sigh only after the sky had completely darkened.
The "Invisible Sword" slowly emerged from his body and began to sway left and right in the air with Lin Li's fingertips.
After consuming dozens of Spirit Stones, it was initially refined successfully.
And just like the "Duck Blood Bottle," after refinement, more information automatically appeared in Lin Li's mind.
Finally, he got the 'user manual'.
Lin Li blinked, and after digesting the information, he controlled the "Invisible Sword" to fly towards a pen on the desk.
The "Invisible Sword" approached swiftly, and the moment it touched the ballpoint pen, it 'vanished.'
Lin Li's fingers moved slightly, and he focused intently.
At first, there was a period of silence. Finally, the ballpoint pen began to tremble, then shake more and more vigorously, until it flew up, unsteadily bumping its way toward Lin Li, hovering in front of him.
