She knew she had to escape.
So, summoning her immense strength, she broke free from the ropes that bound her. What followed was a chaotic fight, during which she managed to steal two horses and then, grabbing the unconscious Liang Yuening and Hong Xiangjun, she fled from Black Wind Camp.
Black Wind Camp was located on the mountain and the night was too dark. She was not familiar with the area at all. Most importantly, she was susceptible to motion sickness from horseback!
Whether it was because of her incorrect posture on horseback, she was terrified of falling off, so she simply lay flat. She shared one horse with Liang Yuening, who was stretched across it, while Hong Xiangjun, initially secured on the other horse, was thrown off like a dead pig as the horse lifted its hooves.
In the end, she had to admit that she had overcomplicated the situation.
Two horses were redundant; one horse would suffice.
