The Ancestor Was Destined for Invincibility, and Even Immortal Emperors Grovel as His Servants

[Imaginative Xuanhuan + One Female Lead + Family Clan + Overpowered Protagonist] Leng Guan transmigrates to the Tianwu Continent and activates the Family System from the start! He unexpectedly receives a System reward: a huge villa! “Damn System! What am I supposed to do with a villa in a fantasy world?” Huh? This System really is useless! It only gives Leng Guan two cultivators with barely any cultivation to guard his home!? Luckily, as long as he develops the Leng clan, Leng Guan can earn rewards! “Then hiring people to move in, taking disciples, capturing slaves... That counts as developing the clan, right? That's not asking too much, is it?” Leng clan member: “Ancestor, capturing slaves can develop the clan too?” System: “Congratulations, Host! You have received one portion of basic cultivation!” One day, Leng Guan discovers that when outsiders answer the System's bizarre questions and pledge allegiance to the Leng clan, the System's rewards become much richer! Leng Guan: “Explain why releasing a lightning eel into the river made Buddha reward me with a hundred pounds of spirit fish?” First disciple: “I get it! Buddha's just a rough, bald monk! Only a fairy deserves to wash Master's feet!” Leng Guan: ??? Old village chief: “You're already a Great Emperor! And you call this basic cultivation?” Neighboring Great Emperor: “Why the hell do two Immortal Emperors stand guard at your front gate!?” Second disciple: “Oh my gosh! Master's cave abode is so beautiful! I don't even dare wear a skirt on the floors~” In a secret realm, a powerful cultivator exploring the place laments: “Run! The Leng clan's laborers are in the secret realm too!” “Stop shouting and run! We can't beat them, not a chance!” Leng Guan: “Cultivation is just so plain and boring.”
