After Practicing for a Hundred Thousand Years, He Went Out and Became a Villain?

No system, invincible and no heroine This was supposed to be a sad beginning. I traveled to a dangerous battlefield and was so scared that I even lost my golden finger. Fortunately, this dog's nest is quite good. You can fish, hunt birds, and pick fruits. It's a wonderful time to be a dog. There is also a cute orange cat for company. I guarantee with my personality that this orange cat is really an orange cat, and it is definitely not an element-devouring beast! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
