Rowan's mind soon brushed past his age nearing a billion years and focused on what would be one of his foundations in the battle ahead, his present stats.
Even while doing all this mental work as he accessed his present powers, he was still heading towards his destination, it helped that he roughly knew everything about his body, but the Primordial Record still helped in clearing any doubt he would have had about his cultivation.
Although Rowan had not been focused on growing his abilities and had simply been focused on crafting, making it possible to reach the level of crafting Source-level treasures in less than a billion years, his attributes and power had been growing without ceasing all this time.
Planning for his battle against Nemesis, Ruler of the Great Desert, and eventually, every Primordial in existence that would seek to stop his rise, even a billion years of planning could be considered too little.
