Taming a horse was all about exhausting its energy. Once the horse didn't have the strength to struggle, it would naturally submit to the person on its back, and that's what An Jing was trying to do—stay on its back without being thrown off, exhausting the horse's energy, so it would recognize her as its master.
An Jing could clearly feel that the horse beneath her was gradually depleting its energy. Its thrashing wasn't as violent as before, but it was still trying hard to throw her off, even suddenly lying down on the ground, intending to crush her as she was thrown to its right side.
An Jing was startled and instinctively moved quickly from the horse's right to its left side, ensuring that even if the horse lay down, it wouldn't press down on her.
Seeing this, Xiao Changyi was about to step forward to end the horse taming and rescue An Jing, but after seeing An Jing's quick movements to avoid being crushed, he retracted the step he had already taken.
