In Lu Ban's field of vision, a variety of information started to bubble up.
This information was presented in the form of text, images, symbols, and equations, like pages of a book that Lu Ban could flip through and browse at will.
Just like the sentence "The fired glass is quite strong, but it cannot withstand bullets," when Lu Ban focused his mind on it, details on how it was made, what local materials were used, and specific strength parameters could be displayed.
Without a doubt, this was information, it was knowledge.
However, this knowledge was already quite widespread, and what it conveyed did not have much of an impact on Lu Ban.
Combined with Lu Ban's True Sight, he could see the information of objects at a glance.
And that wasn't all.
Lu Ban saw that line of text, and a silver pen materialized in his right hand. He lifted the pen and added a small section of writing after the last line of text.
"When knocked upon, it emits a birdcall."
