Squeak.
Inside the stone castle of Black Wind Camp.
Yu Hong sat by the window, feeling the cool breeze from outside as he carved a new rune board.
A few days ago, he tested boarding the ship to ensure his body was fine, and then he returned to create new equipment.
He was attempting to carve a three-dimensional rune board, which involved layering multiple runes on the same board to create a combined effect.
This way, the different runes could produce a collaborative amplification effect, greatly enhancing the board's efficiency.
He breathed in the fresh air from outside, although the air tainted with toxins left only the strong scent of the filter after passing through the breathing valve.
However, Yu Hong *still felt that the air outside seemed fresher*.
