There is no way to be immortal

Lin Xi thought she was an ordinary psychological counselor. After being killed by a abnormal visitor during a consultation, she found that her real identity was Gu Zhisheng, the inner disciple of the fairy world although I am a disciple of the fairyland, my practice is the worst among my peers. What should I do? Then counter attack. Poor innate aptitude? It doesn't matter. Alchemy and marrow washing. Lower world robbery failed? Never mind, then do it again. But when Gu Zhisheng thought that the rough road of cultivation was coming to an end and was ready to fly into immortality. But he found that the fairy he yearned for actually hid many dark secrets. This forced Gu Zhisheng to rethink the significance of cultivating immortals.
