Li Yang felt a little regretful. Had he known, he would have searched Mu Zangfeng's soul when he killed him to see what kind of golden core an Innate Sword Embryo had formed.
He did not necessarily have to follow his example, but the experience he could have gleaned was invaluable.
"Purple Mansion Furnace Art!"
Li Yang suddenly remembered what he had learned from Shen Yaoyin, the heiress at the Nine Cauldron Merchant Association: Mu Zangfeng had also stolen the Xuanyuan Sword Sect's "Purple Mansion Furnace Art."
It seemed this very cultivation art had led Mu Zangfeng astray.
But it was not a demonic cultivation art. With Mu Zangfeng's philosophy of cultivation, becoming an Evil Sword Cultivator had only been a matter of time.
He immediately refined Mu Zangfeng's storage ring and took out a jade slip of the finest quality.
It contained the "Purple Mansion Furnace Art," a secret art of the sword dao.
This was an art practiced by Inner Sword Cultivators, turning the purple mansion into a sword-forging furnace. But it devoured ownerless Sword Pellets, not those belonging to other Sword Cultivators.
Of course, whether they had owners made no difference to an Evil Sword Cultivator.
On the contrary, Sword Pellets with owners contained stronger sword intent and produced better results.
It was just like the slaughter dao.
Slaying demons and defending the Dao was righteous, but slaughtering innocents without restraint was evil.
The same principle applied.
If Li Yang killed only Evil Sword Cultivators, then even if he devoured their Sword Pellets, he would still be righteous, and his cultivation art would still be a righteous one.
A weapon was neither good nor evil. It depended solely on whether the person holding it was good or evil.
But someone whose resolve was weak could easily fall
