Shadow Sewing Technique was the first Ancient Demon Technique learned by Di Shen, and it was a special benefit he gained after consuming the second Demon Essence Pill.
Originally, that night Ye Lingyue and Di Shen joined forces to kill the Shadow Concubine.
Ye Lingyue's cauldron absorbed the soul of the Shadow Concubine, and that night, Ye Lingyue interrogated her, demanding to know who was behind her actions, and what sinister plans the Demon Clan had for the Human Realm.
Unfortunately, the Shadow Concubine was tight-lipped, and no information could be extracted.
Ye Lingyue refined the Shadow Concubine's soul into the second Demon Essence Pill.
Compared to the first Demon Essence Pill refined from the soul of the Jade Bone Demon, Di Shen gained much more after consuming the second.
The soul of the Shadow Concubine, a powerful Sky Demon, was refined into a Demon Essence Pill that significantly boosted Di Shen's demonic power. Moreover, some memories appeared in his mind.
