The Red Pine is a kind of tall and sturdy pine tree, generally standing over thirty feet in height.
Once such trees form a forest, they attract and breed several unique species of pine caterpillars, making it difficult for other tall trees to grow in the vicinity.
Zhou Chun and his companions now found themselves in the Red Pine Forest, which was filled with Red Pines reaching more than a dozen yards high, many of which were over a thousand years old.
The forest floor was covered with a thick layer of pine needles, bristling with various thorny bushes and weeds, making it very inconvenient to walk.
Pine caterpillars as long as one's finger would often fall from the trees above.
In such a place, one couldn't bear to stay without considerable courage.
