Instantly, Lin Lee felt something; he opened his eyes brightly.
Looking at the abyss below, his nanobots are floating up, carrying a huge boulder.
It's emitting black light mixed with some purple gold inscription flickering above them.
"Ha ha ha, today I am lucky; I didn't expect I would encounter the immortal black gold, a spirit class material," Lin Lee laughed loudly and then put away the black gold in his bead spirit space.
"Now a few more similar materials are required, and my Dao book will be upgraded to the great immortal or immortal spirit class; although it is my companion treasure, I can't use it; if it's broken in a battle, then it will damage my soul," Lin Lee decided thoughtfully, then glanced at the lair below, seeing nothing else. He recalled the nanobots.
