Lin Mu continued to think while working on the arrays.
'It is best that we avoid injuries as much as we can. We still don't know how long we'll be stuck here.' Lin Mu thought of as far as he could.
Runes flew all around him while the brush turned into a blur. It never stopped moving, and drew out long lines that wound together to form more runes.
It was as if Lin Mu was simply drawing a single string that got tangled in unique ways.
For most people that saw this, it would be baffling how Lin Mu was doing this, as writing runes was a very systematic process. A single wrong stroke could cause the rune to collapse and when one was making so many, there were bound to be some mistakes.
And a formation needed a large collection of runes to form, thus mistakes had an even greater chance of happening.
Then there was a formation array that held multiple formations, further increasing the chances of errors.
