The Heaven Mending Medicine is a Heavenly Medicine that has the effects for the user to be able to overcome the Heavenly Tribulation and condense a powerful Golden Core. Shenxi used it to condense a Divine Grade Golden Core in her sect, though it was not enough to condense it.
The fruit's location is on the Zang Tian Valley of the Two Realms Area, nurtured using the Heaven Mending Root and mostly used by the Ancient Demon Race for their own personal gain.
