It was a cinch to become a Undead, any necrolyte could help to awaken the dead souls (necromancy), and even preserve their consciousness during life.
The low-rank undeads may have no intellect, but if a legendary Sword Saint or Great Mage decided to be transformed into a undead, as long as his body and soul were complete, he would not even fall below Silver-rank.
Subsequent to the growth of necromancy, that became the easiest path to immortality. Any powerhouse who had acquired considerable strength, would just need to approach the necromancer and sign a secret agreement before the end of their life.
Tempted by this immortality, every year in Xiluo Kingdom, there were secret visits from countless swordsmen in black hoods and sorcerers in a grey robe, these included quite a number of famous names across all countries. There were even some unknown ones who emerged as new powerful undead warlords annually.
