The true function of Hou Yi's Bow is to hold the Arrow of Light. Unlike a Crossbow, it can fire the Arrow Of Light normally without breaking. Due to this, the player can use it to fire it into the opened eye of Hundun, opening the way to the Cosmic Ocean.
- Though bringing the bow all the way to Hundun's Hideaway deep within the Sunken City, all the way from either Jungle or Volcana appears to be an incredibly daunting task, one can leave the bow behind with Waddler in Olmec's Lair, and retrieve the bow from him in 7-1, making taking the bow there a much easier task.
- If the player obtains the bow before reaching Vlad's Castle, they may use the included Steel Arrow to instantly kill Vlad and other Vampires.
