This Necromancer Comes from Earth

A voice, utterly emotionless and cold as electronic speech synthesis, exploded directly in his mind:

** [Ding! Qualified soul signal detected… Binding… 1%… 50%… 99%… 100%!]**

** [The Strongest Undead Calamity System is at your service!]**

** [Host: Chen Mo (transmigrator from Earth)]**

** [Starting Talent: Undead Calamity (SSS-rank)]**

** [Status: Healthy (physical), dirt poor (equipment), socially dead (mental)]**

** [Beginner Quest issued: Host, successfully summon and control your first undead servant within 30 minutes (0/1). Reward: Beginner's Gift Pack x1, System Energy +10. Failure penalty: Randomly lose one bodily function (including, but not limited to, taste, smell, or sensation in a certain area).]**

Chen Mo froze solid, even more than when the cold wind had hit him moments ago.

System? Transmigration? Undead Calamity? SSS-rank talent?
