Twelve-Winged Dark Seraphim

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.

Let Me Game in Peace

After summoning Night Immaculate Sword, he realized that his mental connection with it had weakened significantly. This made Zhou Wen understand that Blood Shaman's blood sacrifice technique was the power to seal Companion Beasts.

Even on his ear, Truth Listener's connection with Zhou Wen weakened significantly. From the looks of it, Evil Nullification couldn't restrain this sealing power.

The Heaven-Opening Scripture had long been engraved, but it didn't appear to be of much use.
