This Teleportation Array was the main means of communication between the cultivators of Chaoyang Palace and Xidu, North Capital. Assistance to Chaoyang Palace from Xidu and North Capital mainly came through here. No matter what, this Teleportation Array had to be destroyed.
For Emperor Jianwu and his allies, destroying this Teleportation Array was very troublesome and the chances of success were not great, but for Qi Tian, simple methods were plentiful. Qi Tian originally wanted to handle this matter personally; during his time at the Saint's Tomb, despite the good outcome, he felt a considerable amount of pent-up anger and had found no means to vent it. Charging into Chaoyang Palace with the Yonghe Stick and fiercely battling the cultivators gathered there would surely allow him to release the anger in his heart.
