Lin Fan was killed and was reborn as a dog in the underworld? Desperate situation triggers the system, randomly draws cards - mosquitoes. Someone else was reborn as the Overlord Immortal Emperor. He had six legs and relied entirely on blood-sucking to survive in the beginning. What's even worse is that the system thought he was too low-priced, so he left the "Blood Origin Manual" and ran away on the spot. Lin Fan: OK, write it yourself. Starting from the ceiling of the toilet, he led an army of mosquitoes to hide during the day and come out at night to suck the blood of warriors and cultivate the body of the demon emperor. Condensing Qi, transforming into shape, transforming into a mortal... Sucking the world of immortal cultivation dry. Geniuses kneel down and beg to be spared, beauties compete to fall into their arms, and is an invasion from another world? Millions of mosquitoes passed through the border, and the gods, demons, immortals and Buddhas all turned into blood packs. The moment Lin Fan turned into a human and sat in the Three Realms, the system came back crying to renew his contract. Lin Fan smiled: "You ran pretty fast back then?"
