You Dare Look Down on Me? Your Son Is Mine!

Gu Chen'an: I'm just an ordinary wage slave. All I want is enough to get by.

System: [Congratulations, Host! You have activated the Primordial Sacred Physique. You have 156 immortal children! They cultivate, and you level up!]

Gu Chen'an (dazed): Wait, the life-source fluid I donated ten years ago wasn't life-source fluid. It was a cultivation cheat?!

[Your child Lu Tianyi cleaves a mountaintop in two at age three. Host's cultivation surges!]

[Your child Gu Xuenai controls ice to save her father at age five. Host awakens Water Element Affinity!]

Gu Chen'an (sipping tea): At this rate, I must be about to ascend.

But when his daughter is treated as a “walking elixir” and put through a sacrificial refinement, he's forced into action:

Gu Chen'an (seething with killing intent): Anyone who lays a hand on my daughter will learn what it means for a father's love to bring mountains crashing down!

(He crushes a shikigami with his bare hands and issues a warning to the Sakura Emperor.)

When another daughter's bloodline foundation is stripped away, he flips the table:

Gu Chen'an (coldly): Mount Shu won't give us a marrow-cleansing pill? Then I'll make one myself!

(Alchemical mastery unlocked. Get me all the ingredients!)

The Demon Emperor descends, only to find himself facing a pack of “dad-protecting fanatics” and their unfathomably driven father.

Demon Emperor (terrified): This dad... is he really just a wage slave?!

Gu Chen'an (helplessly): It's not like I wanted this. The kids are the ones who made me work this hard!
