It is the same idea but it is NOT one of the following: -Dragon Emperor, Martial God -Returning from the Immortal World -Strongest Abandoned Son -Genius Sword Immortal Harem and OPness I think. I am not sure if MC originally came from Earth (RFTIW) or not (DEMG). He dies in the immortal world and ends up in Earth. He left behind two powerful maids whom he regrets not accepting as lovers. His master in the immortal world died to save him fairly early on in the immortal world. He however met a girl in his earth childhood who now looks like his former master. On earth she is a powerful cultivatior and daughter of a bigwig in some kind of global cultivator alliance. Said alliance protects Earth from alien cultivators because Earth's level is getting lower. They have some kind pocket dimension or space fortress for their elites that MC eventually ends up in to start his own faction. I also remember some kind of cultivator VR game or network. It has been a while so I don't remember all that much.
World of Immortals Maybe. I haven't read it or anything, so I don't know. The name and synopsis make it sound like some of your description.
World of Immortals is not it sadly. It might have been a year or two since I last read this novel. I caught up to releases on MTL and I think it was at about 1200-1600 chapters back then. I'm not sure there was even any translations of it. Most of it transpires in modern day Earth with some trips to "secret" dimensions/battlefields to grab some "fated chances"...
Not PMG. This novel is very very similiar to Dragon Emperor, Martial God. I seem to recall several similar plot elements like being a cheat doctor, powerful families competing etc.
