My Pet Is Invincible

Traveling to a parallel world in 2129, the protagonist gets a strange system. "Ding dong! Congratulations to the host for successfully binding the 'Pet Warrior Development System'!" "Choose to raise this Ragdoll cat!" "Ding dong! The ragdoll cat has successfully transformed into a beautiful cat warrior! Combat power +100!" "Choose to raise this golden eagle!" "Ding dong! The golden eagle's bloodline evolves! Cultivate a golden-winged roc! Combat power +1000!" Cats, mermaids, Erha, monkeys, King Kong, and snow foxes all have the blood of the Sky Demon! The pets you raise are all beautiful and handsome men! Being pestered by the cat-eared girl and the snow fox girl every day makes me feel a little bit happy and reluctant to leave... "Please find more favorite pets and develop pet warriors to cope with the catastrophe that will come to the world in 180 days!" This novel and its characters are purely fictitious.
