"What's so interesting about a pile of broken wooden planks?" Although Ximen Guan was somewhat reluctant, he still walked over to the pile of planks, reached out to grab one, planning to casually take a look.
But to his surprise, he couldn't lift the plank despite giving it a firm grip.
Ximen Guan was stunned for a moment, then carefully examined the planks. He picked up a palm-sized plank and struggled to raise it to his eyes.
After looking for a while, Ximen Guan's expression gradually became serious. He released the plank, letting it fall to the ground, cracking the stone floor and making a metallic sound.
Then he crouched down, using the metal ring on his finger to tap on the plank, listening closely to the sound it made.
Afterwards, he took out a magnifying glass he carried with him and almost lay on the plank, examining it closely bit by bit.
Finally, Ximen Guan even stretched out his tongue and licked the plank.
