After successfully fixing the first "pillar", Shen Gu took the simple "obsidian axe" and went to chop down the second small tree.

The "stone axe" turned out to be faster than Shen Gu had anticipated during actual use.

After intentionally choosing a smaller tree with a thinner trunk, he gained some experience in woodcutting through continuous chopping.

So when he chopped down the second small tree, although he was not as physically strong as when he chopped down the first one, it took less time than the first one.
