Capítulo 177: The Advent Of The Last Days.

Guntu followed the gaze of the son of legends and saw nothing but a forest. The Virut plane is mostly forest except for the places with cities. There are no roads on the ground since their transportation system is mostly airborne. The need for wood is also low so the forest has been kept mostly alone. Cutting down a forest can antagonize an old monster that used to live in these woods so it's not worth it to tamper with the forest. 

The love for trees is still deeply rooted in the hearts of many in the race of battle sage monkeys. Times may change, and eras may be swapped, but some individuals that lived through it all are still alive. Trees might have lost their purpose, but there are world gods who still love the trees they had to fight tooth and nail for. You can imagine what such powerful entities can do to you if you dare touch what they have very fond memories of. If you are an Origin god, you will wish you could die.
