Cultivation of Immortality in the End of the World: Being Stabbed Through the Heart by the Savior's Sword at the Beginning

Lai Xu, a retired soldier, spent 3,000 yuan to buy an innocent card. When he woke up, he was transported to Yuquan Peak, a forbidden area of ​​​​the Immortal Sect. As soon as I opened my eyes, I was stabbed through the heart by Xu Qiyun, a fairy with bare feet and gauze, who was extremely cold and indifferent! Surviving the catastrophe, he discovered that it was the "Nothing" card that protected the Lord and saved his life. From Xu Qiyun's mouth, he learned that this world was being ravaged by the "Corpse Resolver Fairy", and she was actually the genius of the Changqing Sect who was responsible for saving the world. After returning to modern times, Lai Xu was shocked to discover that the source of the terrifying enemies lurking in his world that conventional weapons could not deal with was the scourge that Xu Qiyun could not eradicate in his time! With the help of the Nothing Card that can freely travel between the two worlds, he becomes the only variable that can change the future. [Modern Line]: He joined a secret organization, used the method of cultivating immortals, and became a top soldier guarding the city in the dark. [Ancient Line]: He turns future intelligence into strategies, constantly revising and optimizing every plan of the Savior Fairy! "Xianzi Xu, there are loopholes in your formation thirty years from now, so you have to use this modern formula to calculate it!" "Captain, the weakness of the corpse-removing immortal is the Gui Water Thunder Technique, prepare the electrolysis equipment quickly!" He has modern technology in his left hand and ancient magic and magic in his right hand, running between the two apocalypses. This time, he vowed to join hands with the savior of the past to completely end the disaster in two time and space at the same time!
