On the top floor, the red-armored guardian was only growing more depressed. If Dyon hadn't spent three weeks, he would have already cleared the sky castle. When was such an overwhelming genius born? It was borderline unfair. To think he did all of this with his sick wife in his arms. If he had been willing to let her go, he would have finished even faster.
The blackened doors continued to grow. There was a good portion of the treasures that remained useless to Dyon. More cauldrons, more alchemic robes, and more techniques. But, others were more useful in the sense that they would help him grow his empire.
He found a room filled with soul stones. Although the actual purpose of the room was to show of the formation at the center of it that sped up soul cultivation by almost 50%, Dyon didn't care about it. This was because the [Dao of Array Alchemy] had a more efficient formation that increased soul cultivation speed by almost 100% percent.
