This is the only Immortal City in the Eastern Wilderness, and the very foundation of the Five Elements Sect, where even if only Zhou Ye alone were holding it down, it could still fend off Nascent Soul Cultivators for decades.
"Junior brother, Hunyuan Immortal City does have a Medium Transporting Formation."
Mo Douguang reminded him, even if they could breach the Hunyuan Immortal City, Zhou Ye could always escape using the Teleportation Array before its fall.
The Medium Transporting Formation was capable of connecting with all the Small Teleportation Arrays within its range, which meant Zhou Ye could flee to Yun Meng Ze, or even to any one of the seven nations of Wu, Ming, Yan, Ji, Hao, Chun, and Qing that had Transporting Formations.
Even if they waited until Zhou Shengqing transformed into an Embodiment Nascent Soul and amassed a great army to conquer Hunyuan Immortal City, capturing Zhou Ye alive would be an impossible feat.
