The Lin family, a family of immortal cultivators, was destroyed overnight. Lin Yuan, the last heir, suffered a blood feud and was hunted to death. At the moment of falling off the cliff, the family's treasure "Key to the Realm" suddenly awakens - this door leads to a real world of cultivation. Immortals from other worlds are watching with eager eyes, ancient monsters are about to awaken, and Blue Star is facing an unprecedented catastrophe. Lin Yuan turned around and walked into the door of the National Security Bureau, slapped the fairy door key on the table: 'I want to hand it over to the country. ' From that day on, the era of national destiny cultivation began. The missiles locked onto the flying sword, the radar captured the consciousness, and the fighter jet formation covered the charge of the Jindan monks. When the Immortal Sect from another world invaded in a large scale, what they saw was - 1.4 Billion people practicing the same method, and 9.6 Million square kilometers were the base of the formation. "Those who offend our Blue Star will be punished no matter how far away they are."
