My Hotel is Connected to All Realms

[No CP + Not a Good Person Protagonist] Ling Yu is dead, dead in a hotel. Her blood stained the hotel, and it's now bound to her! Then, the hotel revealed a side of itself to her: a gateway to all realms. So, Ling Yu helped guests from the apocalypse build the strongest base, helped guests from the immortal realm kick the scumbag immortal, and helped guests from ancient times gain power... Later, rumors spread that if you encounter difficulties and pray sincerely, a magical place will appear, warm as spring, sheltering you like home. Furthermore, the owner of that place is extremely powerful, and as long as you're willing to pay the price, she will grant you whatever you desire. ... Ling Yu: I'm just a worker, taking advantage of the hotel, not a wishing idiot! Hotel: That's right! I'm just a hotel. Who knows what this contractor is doing? He's messing with it!
