It had been sixty years since the apocalypse began, and almost everyone knew the two criteria for a mutated creature's evolution: physical size and energy levels.
This little rat was a tiny bit smaller than before, but the difference wasn't obvious. As for its energy... Gu Xi frowned slightly.
The energy inside the rat was fluctuating wildly and was extremely unstable. This situation... felt strangely familiar to Gu Xi.
In the next instant, a small green sprout shot out from Gu Xi's fingertip, instantly growing to over ten feet long and binding the Mutated Rat King that was frantically digging a hole.
The captured Mutated Rat King seemed stunned for a moment. Its small, red, bean-like eyes narrowed slightly, revealing a look of confusion. But it quickly came to its senses and started squeaking nonstop at Gu Xi.
Unfortunately, no one could understand the language of rats.
