Shi Feiyang had not expected the Taiyin Hunyuan Ancestor to actually offer to proactively teach him the method of forging the Heavenly Demon Immortal Slaying Sword.
To tell the truth, he was somewhat tempted.
The Heavenly Demon Immortal Slaying Sword was the ultimate hope for the Evil Sect during the third swordfight between the righteous and evil factions in the Shushan World, but unfortunately, it was never forged.
Unlike the Purple and Blue Double Swords, which were simply flying swords like Purple Ying, Green Rope, and Nanming Li Fire, the Heavenly Demon Immortal Slaying Sword was more akin to a Magical Treasure.
It could do more than just cut people; it had many wonderful uses of the treasures of the Demon Cult.
Shi Feiyang did not plan to forge a sword immediately, but he was very curious about how it would be done.
