Synthesis: Alchemy Room, Formation Room, Talisman Room, and Artifact Refining Room (Monthly Votes Requested)

Building synthesis had first appeared alongside the [Artifact Refining Room]. Back then, Ji Yuan had wanted to seize the chance and upgrade it at once.

But the Panel had told him that synthesis was only possible when the [Artifact Refining Room], [Alchemy Room], [Talisman Room], and [Formation Room] were all the same level.

At the time, Ji Yuan's skill in the Artifact Way had not been enough to support upgrading the [Artifact Refining Room] to Level Two, so he had no choice but to leave it.

Later, to upgrade the [Spirit-Energy Cannon] and gain a means of saving his life, Ji Yuan had ground his Artifact Refinement Technique all the way to the Second Tier.

Once the [Spirit-Energy Cannon] reached Level Two, it gave him an attack nearly as powerful as a Golden Core Peak strike.

The good news had made Ji Yuan forget all about upgrading the [Artifact Refining Room], let alone synthesizing buildings.

Now that he remembered, though, this was his chance.

To synthesize the buildings, he first had to upgrade the [Artifact Refining Room]. With that thought, Ji Yuan summoned the Panel and took a look.

[Upgrade requirements: Middle-Grade Spirit Stones ×20, Azure Nether Iron ×4 pieces, Earth-Spirit Mica Stone ×2 jin, successfully refine one Spirit Artifact (unmet)]

Azure Nether Iron and Earth-Spirit Mica Stone were both fairly common artifact-refining materials. Back in Lanshan City, Ran Kui had even taught Ji Yuan how to extract Azure Nether Iron from Azure Nether ore.

But refining it himself now would take far too long.

So Ji Yuan turned his boat around and headed straight for the Island of All Things.

The Hundred Treasures Pavilion sold common Second Tier artifact-refining materials like these. They would simply cost him more Spirit Stones.

And Spirit Stones were the one thing
