"Grieving Grass, Falling God Flower, Parasitic Poison Ginseng…"
Lu Changsheng had collected thousands of highly toxic Heavenly Materials and Earthly Treasures in the Valley of Doom.
Some of these herbs were unique treasures to this forbidden area of the valley.
With thousands of Heavenly Materials and Earthly Treasures, and each can be gifted to disciples over and over, the materials Lu Changsheng collected in the Valley of Doom would be sufficient for him to teach disciples for quite some time.
Lu Changsheng even harvested a pile of insect eggs.
These Demonic Insects could continuously produce venom.
However, Lu Changsheng had not found the eggs of the Devouring Demon Worm.
Suddenly, Lu Changsheng's attention was caught by a waterfall.
He hovered in midair, overlooking the area, and saw that the river where the waterfall was located turned out to be a straight chasm.
The entire area was crisscrossed with ravines and sword scars.
