Let Me Game in Peace

Novel Summary
1 drop of blood = 1-Up
Other people game overnight, I game overnight and bleed.
Ever since the dimensional storms descended upon Earth, numerous dimensional zones have appeared, bringing with them all kinds of dimensional creatures—Immortals, Buddhas, Devils, Angels, Elves, etc.
Yet, all these strange dimensional zones can turn into dungeon instances on my phone. Other people risk their lives adventuring, I spend all my time gaming.
Monsters drop dimensional crystals that boost stats, imbue new skills, and join me as Companion Beasts. These Companion Beasts fight alongside me or alone, augmenting me with their skills and strength. Rare monsters in real life? I’ll just restart the game with a drop of blood to grind it.
I really need a blood transfusion.
