Ye Mo and his group were looking for Song Yangzhu and the others as well as the water weed at pill towers.
What surprised Ye Mo was that a lot of people knew about the water weed, meaning that it wasn't something very rare. However, Ye Mo was disappointed to find that there weren't a lot being sold. It wasn't that it was too precious but because this herb was too low valued. Also, it was very dangerous to pick this herb.
Water weeds usually grew on the distant islands in the distant sea. Most of them time, they were protected by level five or even level six beasts. Many marine beasts liked to eat water weeds.
So, one had to kill the guarding beasts first before collecting the mere level four water weed. On top of that, the water weed could only be made into the water algae pill. It's use was for water element cultivator to cultivate. However, it's effects were far weaker than the clear essence pill and worse than even benefit essence pill.
