Returning to Build Up a Primitive Tribe

I woke up with a little half-baked knowledge and found myself in a primitive tribe where people lived off raw meat and blood.

The System told me: Want to go home? First, become the tribe’s babysitter and get their favorability up to 100!

Starting fires by drilling wood, making pottery, smelting iron... Luckily, the tribe chief was a devastatingly handsome god of war who trusted me without question.

But my knowledge of physics and chemistry wasn’t complete! When my iron smelting blew up the furnace, he took all the blame and faced every accusation for me.

I helped the tribe rise to power with gunpowder and iron tools. Just as the favorability finally hit 100, the System forcibly sent me back to the modern world.

I begged the System to let me return, but it coldly refused.

Until one day, it suddenly blared an alarm

My chief, my love, wait for me! This time, I’ll tear through time and space to return to you!
