"The law of nature stays the same, even in the post-apocalyptic era," Li Yueshan nodded.
"They're fighting to upgrade. I wonder when the battle will end," Luo Yuanjun picked up the telescope and started observing again while murmuring to himself.
Through days of fighting, some creatures had to kill and eat quite a few others to upgrade. Some killed and ate their opponents but suffered fierce attacks before they could upgrade. Meanwhile, some lucky ones managed to upgrade successfully after killing and eating only one opponent.
The number of those creatures had been reducing rapidly, and at least half of them had died at the moment. Some of them were killed by the others and some died when failing to upgrade. Only the successfully upgraded ones were allowed to leave. The rest of them had to stay and keep fighting. In the end, they would either die or break into a new level.
Apparently, not many of them would survive.
