Yu Ming previously only created a hole as big as his body in the barrier, and he also said that their time was tight, and that was why Bai Chen and Wu Jingguo could only think about how they could run through the barrier without thinking about anything else.
In the end, only the three of them entered Dong Lang, whereas the three stallions were left outside the barrier. Bai Chen panicked a little when he just remembered that the white horse wasn't with him when he was already at Dong Lang.
Of course, he panicked because he knew that the white horse belonged to Wu Jinhai, and it was also said that the horse was one of Wu Jinhai's favorites. However, Yu Ming later said that the three horses were not ordinary, and they would definitely be able to survive outside the barrier even without their master. Yu Ming also said that the Emperor's army would probably arrive at the place soon, and they would surely guard the horses.
