Guardian of the Primordial

With the Age of Immortals about to begin, Li Shan, a cultivator of the Xuan Xian realm, is carelessly assigned by his master to guard the gates of Jin'ao Island. Faced with his unapproachable senior disciples and senior brothers who rule the entire island, he initially plans to use a small formation to get by. However, he unexpectedly awakens the Gatekeeper System: every time someone attempts to breach the formation, he grows stronger! From then on, the weakest disciple of the Jie School blocks the gates and sets up challenges, while various immortals and gods take turns trying to defeat him, only to fail repeatedly. How about a Saint? Once they step through this door, everything must follow his rules!
