Signed in for a Thousand Years and Hatched the Wife of the Strongest Mythical Beast in the Fairy World

Li Yunxuan, originally an ordinary disciple of Xuantian Sect with mediocre qualifications, accidentally traveled through time and picked up a mysterious sign-in system. Can you get treasures by signing in every day? Can you give me an egg? It sounds good, but who knew this egg has its own little temper! After signing in for thousands of years, Li Yunxuan has risen step by step relying on the sign-in system. The proud daughters of heaven from all the major sects are surrounding him, but Li Yunxuan's biggest task every day is actually... Feeding eggs? ! Yes, you heard it right, it's that mysterious egg! Any competition between geniuses or battles between sects must come after the daily feeding of eggs! ! ! !
