Professional for All: Obtain the Only Hidden Profession at the Beginning

This is the first time a newbie writes, so don't comment if you don't like it. Lin Feng inexplicably traveled to a world where games and reality merged, and he was a person with the same name. The originally awakened ordinary profession has become the only hidden profession, Necromancer. You can summon undead creatures to fight for you, and you can rely on yourself. Lin Feng also began his own journey to rise from another world. (Not undead natural disaster flow)
