To build a body fitting for a god, a sacrifice is naturally needed. Six million lives might sound like a large number, but in the grand scheme of the world it was a tiny drop in the ocean.
A single mountain alone held more mineral wealth than a pile of six million corpses, but at his current stage, refined human essence was the only material available to him.
What did he need to achieve such a goal?
First was what he had stated since the first day he descended into this world.
Power.
Even with enough material at hand, without sufficient power he couldn't make it happen. Right now he was at the 9th stage with 10,000 spirit stones in his ring, enough to jumpstart the process.
Second was obstacles.
The three great powers were much stronger than him. To fight all of them alone he would need to be at core formation stage at minimum, which was borderline impossible at this point.
