Upgrading the Emperor's Gold Blade was a straightforward process.
Lu Yuan had already gained experience from refining the other three pieces of the Emperor's Qi Luck Dao Fruit Immortal Artifacts. Repeating the process this time was nothing more than a facile task.
It only took about a year for him to complete the upgrade of Jin Qingyue.
The process went exceptionally smoothly, without any hiccups.
He even saved quite a bit of surplus materials, which he then coupled with others from the treasury, and crafted another new Qi Luck Dao Fruit Immortal Artifact.
Due to the scarcity of materials, the newly forged Dao Fruit was merely a small Jade Pendant, with a rather shallow foundation, barely making it to the level of an Immortal Artifact.
Such a new Dao Fruit Immortal Artifact was of course only in its initial form and was definitely going to be strengthened later on, just like Jin Qingyue.
