Possess the System, Draw Pangu's Bloodline from the Start

What? I've become a System?!

Huh? There's a giant over there! Draw blood, we have to draw blood!

In an instant, an enormous invisible syringe plunged into the giant and drew a full tube of blood!

"Awooo!"

The giant awoke, clutching a massive axe and slaughtering everything in sight! Countless living beings fell beneath the giant's axe.

"Nani? Is that Pangu? Did I draw his blood?!" At that moment, Li Ze was stunned!
