Use the Pokémon System to Cultivate Immortality!

Lin Tian traveled through the world of immortality and awakened the Pokémon system! "A first-level monster, an iron-skinned pig, lv: 10, upper limit 20. Can mutate." "A fifth-level monster red dragon, level 70, upper limit 75. Cannot mutate." "Unlock new features of the system! You can summon any Pokémon! Mewtwo, Rayquaza..." He thought that Lin Tian would have to deal with the wild world in his life, and he couldn't even think about it like those big sects who had to do homework and complete tasks from nine to five every day. Until one day, he discovered that his pet ball could even capture people! ......... The avenue collapsed, and several figures stood everywhere. "Lin Tian, ​​I've tolerated you for a long time!" Empress Tan of Yaochi opened her mouth lightly and used the Nine Heavens Xuanyin Jue. Unexpectedly, Lin Tian's hand just shook slightly, and a purple ball flew out.
