When the two retreated to the other end of the train car, Bull Shield had already split open with a long vertical crack. The Butcher Carriage Monster threw back its head and charged, but it was stopped by the Non-Knotting Thread Xu Huo had pre-emptively laid inside the car. These threads, connected to the tables and chairs, were densely arranged across the aisle. When the Butcher Carriage Monster blindly charged ahead, it immediately pulled up the tables and chairs on either side and squeezed them towards itself!
Guns that shoot bullets are powerful, but the person holding the gun can't guarantee they'll hit the target with every shot. Gadgets are the same, if the person using them can't keep up with the speed of the Butcher Carriage Monster, small-scale, targeted gadgets won't unleash their full power. So, Xu Huo's move wasn't aimed at trapping the Butcher Carriage Monster but at slowing down its speed!
