Xuanhuan: I Am a God in a Primitive Tribe

What do you do when you transmigrate to a primitive planet in 10,000 BC?

Good thing I have a civilization-upgrade System.

Population and pets come from grinding; materials come from scavenging.

What? You say other people's Systems can summon heroes to become their followers?

Then we'll raise our own heroes.

Want a young general who tramples the Xiongnu beneath his horse? Sure.

Want a peerless warrior who can take on a thousand? Sure.

Want a genius strategist with unmatched cunning? Absolutely!

With a System, I can even raise Sun Wukong if that's who you like.
