The Age of Mountain and Sea Beast Souls

This is a fantasy world where everyone awakens their beast souls. Everyone starts the soul awakening ceremony in their youth, and can only have one natal beast soul in their lifetime. The origin is completely solidified at the moment of awakening, and there is no way to graft the broken soul or replace the origin of the alien beast. Beast souls are divided into two major reincarnation mechanisms: mortal souls and elite souls are mortal beasts with no quantity limit, and beast souls of the same kind can be born in large quantities; beast souls of all levels of mysterious beasts and above are all drawn from the "Book of Mountains and Seas". There is only one owner of the same kind of beast in the world. After the death of the host, the beast soul will reincarnate again and wait for the new awakener. As the original beings of heaven and earth, the ancient creation spirits can never be contracted by humans and can only occasionally scatter chance treasures. All beast souls are born with independent minds. The higher the level, the more mature the mind is and can communicate with the host in the sea of ​​consciousness. The four ferocious beasts have their own violent and turbid air that corrodes the soul. A master with weak willpower can easily be controlled by the ferocious beasts in reverse. Beast souls of all levels are born with two inherent skills as standard, and the upper limit of acquired skills is determined according to the level. The beast souls have a unified seven-stage growth path: Shadow period→Consolidation period→Physical body symbiosis period→Soul shadow incarnation period→Original manifestation period→Throne of law period→Original unification
