Chapter 124 Electric Ray, World Rift

At 4 p.m., in the Reading Room, Jack Clark quietly flipped through the fifth volume of the Mutated Beast Encyclopedia.

Over the years, too many mutated creatures had appeared worldwide, with varying strengths. Some could even be tamed and bred, just like the pigs and sheep of the past.

One of the largest mutated beast breeding types currently includes the mountain woolly pig, which evolved from the former mountain black pig.

After mutating, these creatures grew several times larger than before. Fully grown adults could weigh up to two tons, had a high yield of meat, and could survive on feed and vegetation alone.

Of course, even if such creatures weren't particularly bloodthirsty or wild, they could unleash tremendous strength if slightly angered, which ordinary people could not handle.

Therefore, those large breeding groups would usually take over more than a dozen mountain ranges and hire cultivators of the Second or Third Layer Heaven to manage them.
