The One-Hundred-Year Period Has Come, and the Identity of Cultivating Immortals Can No Longer Be Hidden.

In 2025, a video of "Using a sword to overcome a tribulation" went viral on the Internet, triggering global speculation about the "hundred-year covenant"! The protagonist of the video, Zhang Yu, is a professor at the Department of History at Peking University. He is actually an old monster at the peak of the golden elixir stage who has lived for a hundred years! He traveled thousands of miles with his sword just to save his apprentice, but unexpectedly he accidentally opened the prelude to the end! "Three months! Alien invasion, countdown to global doomsday!" Mr. Mo's words made all the big guys in the cultivation world turn pale! What kind of century-old agreement? What secret agreement? In the face of absolute disaster, everything turned into nothingness! Zhang Yu sneered, these "old men" who only care about making money finally panic? [The integration plan of the cultivation world is launched! → Unify the resources of all sects and centralize rare spiritual stones, medicinal materials, and techniques when spiritual energy is exhausted! → The Chinese Academy of Special Warfare Readiness was established, and Zhang Yu personally took charge as the principal! → Recruit talented boys and girls to inherit the lost path of cultivation, and vow to build up combat power to resist the invasion within three months! "Look, isn't that Uncle Jiu? Isn't he already dead?" Wencai and Qiu Sheng were seen standing behind Uncle Jiu. They led thousands of zombies to confront the alien beasts. At a time of crisis in China, a picture of heaven and earth appeared in the Qinling Underground Palace. Emperor Qin's voice spread throughout China, "Anyone who offends our country will be punished!" "Wake up!" The terracotta warriors and horses that have been sleeping underground for thousands of years have collectively awakened. Facing the invasion of aliens, Zhang Yu no longer hides and takes action, vowing to build this land into the strongest fortress against aliens! "A hundred-year agreement, I, Zhang Yu, will put an end to the alien race!"
