Create a Dynasty of the Dead in the World of Immortality

My name is Feng Feifan. I traveled to the world of cultivating immortals and was accidentally bound to the Necromancer system. I received a novice gift package, a Necromantic Orb and a Necromantic Staff. There were no other rewards, not even some simple task releases. The only good thing was that I seemed to have no lifespan limit. I worked steadily step by step, accumulated knowledge, and established the Necromantic Dynasty.
