If they wanted to go to Northern Xinjiang, they needed a guide.
Both Zhang Xiaohou and Mu Bai once set out from the Ancient Capital and walked all the way westward to reach the high-altitude Xinjiang. They also walked to the northwest and wandered for a long time near the border of Northern Xinjiang. Both had traveled to the northwest region of the Ancient Capital for a long time.
It just so happened that both were present this time around, too.
Mo Fan thought Mu Bai would stay in Fanxue Mountain. After all, Mu Bai had more responsibility after becoming famous in the battle in Fanxue Mountain. However, he still came from far away to the Ancient Capital to join Mo Fan and the others when he heard they were looking for the Sacred Totem Beast.
Zhang Xiaohou arrived the next day.
After Mo Fan reported his itinerary to Shao Zheng, he was happy to hear it and immediately talked to Commander Hua.
