The sword cultivators from the Great Barren Sword Sect were abnormal. When they reached the Foundation Establishment Stage, they would start to cultivate many magic items.
They did not just cultivate swords. Anything was possible, it just had to depend on the cultivator.
Before forming the Aurous Core, the cultivators would cultivate all the magic items that they had, which were all infused into one cauldron. At the end, they would obtain one magic sword. Along with the special cultivation manual of the Great Barren Sword Sect and the infusion of a cultivator’s supernatural awareness into his sword, he could reach the Aurous Core Stage.
After forming the Aurous Core, this magic sword would be re-cultivated to increase its standard. It would become the first magic item of the Great Barren Sword Sect cultivator.
