Apocalyptic Extension!

Three days later, in the northwest edge of the Furious Bears Tribe's territory, beside a zigzagging valley…

Hundreds of years ago, there used to a running river in this place, but it had dried long ago due to climate change.

The riverbed, infiltrated by the underground mother lodes, was as red as blood. Looking from afar, a crimson river seemed to be still flowing slowly.

The hundreds of square kilometers nearby were uninhabited, but weird sounds were echoing in a forsaken mine.

The dense sounds seemed to suggest that a tornado was savaging the cave, or that two primordial beasts were fighting each other in the depths of the mine. Occasionally, deafening explosions would burst out from hundreds of meters below the ground, blowing smog mixed with stone powder of various colors out of the cave.

Finally, everything went peaceful again that afternoon. An exhausted man, dragging quite a number of fully-loaded carts, crawled out of the cave.
