Yes! Lord Sect Leader!

The original civilization of cultivating immortals ended, and the three major sects ruled the entire world. Immortals are extremely powerful and can move mountains and seas with just a few moves, leaving the world devastated. In order to end the never-ending battle between them, the three major sects invented the "alliance sect leader rotation system" and held a round of alliance sect leader selection every few hundred years. This is the fourth millennium since Li Lin achieved unity, and it is also the fourth millennium that he has entered the "Zhangyin Pavilion", the most important department of the "Comprehensive Action Department" jointly established by the three major sects, a super secretariat serving many high-level sects. Li Lin: "My beloved lord, what is the defense strategy of our world of immortality?" Sect Master: "Protect the world of immortality?" Li Lin: "It is to make people in the world of immortality believe that they are protected." Sect Master: "What about the demons outside the territory?" Li Lin: "Of course the demons outside the territory know that they are not protected!" This book is also known as "The Immortal Office", "The First Fire Captain in the Immortal World", "My Brainless Master and Me", "AUV Isn't this the Mahayana Master"...
