As for other offensive effects, He Song simply didn't take them seriously at all.
After all, He Song had already successfully refined his life-bound artifacts.
The Earth Vein Spirit Pearl, a defensive and offensive marvel, surely wasn't inferior to a mid-grade spiritual device, was it?
This was something He Song was well aware of.
The power of the Earth Vein Spirit Pearl was far greater than that of the Willful Purple Cauldron.
However.
Even knowing all this, and knowing the Willful Purple Cauldron was unlikely to greatly enhance his own strength,
He Song still went ahead and refined the Willful Purple Cauldron, planning to successfully integrate it.
Only by doing this could He Song avoid revealing the ace up his sleeve, the fact that he had already refined his life-bound artifacts.
He Song's life-bound artifact, the Earth Vein Spirit Pearl, was indeed an ace up his sleeve.
