Fifty mother insects glided downstream.
During this time, Zhao Ke and ten Insect Witches, for the most part, did not exhibit any fluctuations in vital energy. They merely controlled the direction of the Magic Ship simply.
Only when encountering obstacles or grounding did their bodies exhibit a significant surge of vital energy. Using the water veins, they repositioned the Magic Ship and let it drift toward the destination.
The speed of the Magic Ship was not fast; it drifted merely 20 miles in one "hour".
Though slow, the pace was secure.
Whether it was the Magic Ship, mother insects, or Zhao Ke, the vital energy fluctuations caused by their spellcasting were minimal, and the traces of spellcasting were highly concealed, making them nearly impossible to detect.
This was what made the Insect Witches troublesome; from a great distance, they could strike at the enemy undetected by gods or ghosts.
