The Situation on the Earth's Surface

At that time, all kinds of underground creatures were devouring each other in the areas where they had been gathering.

The level-nine creature in the underground realm wasn't the only one that had a great appetite. The underground creatures on the earth's surface had a huge appetite for food and energy as well.

Currently, they had been fighting each other crazily. They were killing and eating each other, but weirdly, they didn't attack the ones that were feeding. They didn't attack their own kind either.

Each battlefield was guarded by several powerful creatures at level seven or eight. They each guarded one side, quietly watching the chaotic battle among the lower-leveled underground creatures. Some of those creatures were of their own kind, but they had only been observing quietly.
