Because it's all soil here, the cave dug out wasn't solid enough. The cave was actually sturdier when burned.
The soil layer inside the cave is vitrified, so there's no fear of poisonous insects hiding in the earth.
Lu Yu just stepped into the cave when a torrential rain fell behind him. Immediately after, he witnessed silver snakes dancing in the sky, with lightning bolts striking the ground.
Seeing the glow of the fire appearing after the lightning faded in the distance, Lu Yu was somewhat delighted, "Thunderwood?"
True Thunderwood is the wood revived with vitality after being struck by lightning, sprouting green buds. Such trees undergo lightning strikes periodically, each time undergoing rebirth.
Trees that can survive for decades, even hundreds or thousands of years, reborn in thunderstorms, are true Thunderwood. They are extremely valuable and are the perfect choice for refining thunder attribute spirit weapons and spiritual treasures.
