Guardian of the City

I am a person who has traveled from another world. There is only thin spiritual energy here. There are no various cultivation sects. There are no various spiritual beasts, immortals, elixirs, and gorgeous magic. There are only technological civilizations and medical treatments relying on precision instruments. Let's see how I can embark on my path of cultivation on this backward planet. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
