Western Fantasy: from a Downtrodden Lord to an Uncrowned King

[System + time travel + wits + group portrait] After traveling through time and becoming the exiled eldest son of a nobleman, Aaron awakens to a taboo system. Everyone knows that those who make covenants are chosen by heaven, and the Pope can make covenants with up to five people. As for my system, there is no upper limit. When my stepmother used moldy food and killers to bid farewell to me, when everyone was waiting to see me freeze to death in the northern wilderness. I had silently made a covenant with my first Cat Lady Covenant, and her power began to flow through me. They thought those who were exiled were abandoned sons, but they didn't know that every time I made a covenant with someone, I would have an extra piece of the chosen power. In the future northern border, the Elf Queen is my sword, the dragon is my shield, and the Dwarf King forges my soldiers... Only then did the Pope and his family, who were sitting in the royal capital, realize with trembling that the one they had exiled with their own hands was the only God.
