This genius imparted the technique to other powerful cultivators. After cultivating it, their strength would increase dramatically. However, they were unaware that they were slowly becoming the genius's cauldrons.
Once the time was right and the cauldrons were powerful enough, it would be time for the genius to harvest. He would have the cauldrons use this technique to absorb True Sun Fire one by one, deliberately letting them refine the True Sun Fire into their own Life True Flame!
At this point, the endless True Sun Fire would burn the cauldrons to ash. But after the True Sun Fire incinerated all their Dao Practice and destroyed their Life Furnaces, it would transform into a True Flame Order!
By burning the cauldrons, the genius could absorb the refined True Flame Order. The more True Flame Orders he absorbed, the more powerful—even invincible—his evil Striking Technique became!
