Werewolves Cannot Become Immortals

He is an orphan of an extinct nation, possessing supernatural powers without knowing it. By chance, he joined a small local sect, Luohuamen, and learned some Taoist skills. He also gained the love of his senior sister. After the two fell into the abyss of all spirits, they encouraged each other and escaped from danger. It was precisely because of this experience that his senior sister was devoted to him. After that, he went to the higher-level sect of Luohua Sect. With his innate advantages and hard work, he actually mastered two peerless skills that no one could practice at the same time. However, one day his identity was revealed and he was almost killed by the righteous people. He escaped the disaster by relying on the martial arts he learned and the spell cast by his ancestors thousands of years ago. Later, while working with the wolf, he gained the favor of the Demon Sect and the Heaven and Earth Alliance, both of which wanted to recruit him. Let's see how the protagonist survives in this world where strength matters, and how his love affair with his senior sister Ye Qianxun and the demon sect girl Mo Xiner will end. In addition, why did he give up becoming an immortal when he had a chance to become an immortal? Heaven and earth are benevolent, and all things are like dogs.
