Dozens of large flying ships, including three Dark Turtle flying ships, nine Green-tail Scorpion flying ships, eighteen Fire Wyrm flying ships, and thirty-six Green-scale Serpent flying ships, were flying slowly at an altitude of about ten miles from the ground, each appearing empty.
Under Great Yu's military system, every province was equipped with only a limited number of standard flying ships that were used solely as a means of transporting troops. If any province wanted to acquire other large instruments of war, it must use its own funds to purchase from the Temple of Craftsmen under Liangzhu's Military Court. However, these flying ships were purchased by Ji Ao at his own expense for Wu Qi.
