Refining Earth Immortal Treasures (Part 1)

The Five Thunder Immortal Slashing Sword was Shen Ruyan's lifelong treasure, a weapon that had followed her from the lower realms to the present day. It was undoubtedly the most familiar and easiest to wield of all her treasures. Having undergone numerous upgrades and refinements, it had proven itself in battle, with an impressive record of slaying immortals, making it a truly formidable weapon.

However, as Shen Ruyan's cultivation had rapidly advanced with Jiang Chengxuan's help, the Five Thunder Immortal Slashing Sword was beginning to lag behind in terms of power. Her cultivation had risen at an astonishing rate, thanks in part to the Bodhi seed's effect. Yet, unlike Jiang Chengxuan's system rewards that could directly enhance the quality of treasures, the sword itself could not benefit from such upgrades.
