The rune instrument manufacturing skill promotion region in the tower of time was as large as 5 football courts. This region was a huge semi-closed crystal Mongolian yurt with a portal.
Out of great curiosity, Zhang Tie entered that region through that portal.
Being different than that simple and spacious space of the other regions in the tower, this rune instrument manufacturing skill promotion region shocked Zhang Tie for quite a while.
Given its look, the region was only as large as a few football courts; however, after entering it, Zhang Tie discovered that the inner space of this Mongolian yurt was over 100 times greater than that 6f the outside. This was a bizarre space whose inner space was greater than that of the outside.
