Thus, Tie Dan and Tang Tong began their days of chopping wood at the foot of the mountain.
As Tang Tong said, the so-called chopping wood is not merely "logging—!".
Ordinary firewood is actively collected by the Tang family, a noble family from Qianzhou, as Tribute to the mountain, so it's unnecessary for them to gather it.
What the sword boys of the Sword Sect need to do is wander aimlessly all over the mountains, relying on their own Immortal Fate and keen sight to gather various Lingzhi Immortal Fruits at the foot of the mountain, considered the most basic resource gathering task for the sect.
To explain it more clearly.
This means using your own Immortal Fate and Luck to collect the Heavenly Materials Treasures you've earned through experience and handing them all over to the sect.
Paying tuition.
Tie Dan understood this too.
