Another unique trait of the Nephila Black Horse made it seem like they were born for this role.
At first, even the caretakers had no idea what the Nephila Black Horse's rope-like tail was for.
It looked like a thick rope, but unlike regular rope, it was incredibly tough, rivaling the hardness of the Nephila Black Horse's back.
Although this rope-like tail was significantly longer than the tails of ordinary horses or cattle, it was still far too short to be used as a cargo tie-down.
For a long time, people tinkered with it but couldn't figure out its function.
Some even speculated that the tail was just a random mutation that happened during the Nephila Black Horse's evolution to match its overall appearance.
Then, one day, during a collective stroll, a stroke of luck led the caretakers to discover the tail's true purpose.
