The modern city suddenly suffered a "heavenly change", and the world was covered by the rules of the popular fairy tale game "Nine Heavens Immortal Path". Monsters were rampant and spiritual energy was revived. The orphan Lu Yan accidentally awakens the "Xiantu System" panel, which can convert real-life behaviors into game data, kill monsters, upgrade equipment, and develop spiritual pets and Taoist companions. He started from struggling to survive, and relied on the system to master swordsmanship and talismans, and his strength improved rapidly. On the way, they met Ling Shuang, a cold sword cultivator, and Zhao Meng, a simple and honest physical cultivator. Together, the three of them explored ruins and secret realms distorted by the rules of the game. As the level increased, Lu Yan discovered that there seemed to be human control behind the "Celestial Change", and the system panel concealed the truth of the world. He breaks through all the way to the stage of becoming a god and overcoming the tribulation, uncovering the conspiracy of the advent of the game. Finally, facing the threat from higher-dimensional "players", he chooses between protecting the earth and pursuing the peak of immortality, and determines the future of civilization.
Purpose: Lu Yan awakens the system after the "Celestial Change", starts from the bottom by killing monsters, explosive skills, upgrading monsters, and gradually masters the power of cultivating immortals. He teamed up with Ling Shuang and Zhao Meng to explore the ruins of the city and the secret realm of the dungeon. While improving his strength, he discovered that the "change in the sky" was not an accident, but a conspiracy by higher-dimensional beings to use the earth as a "game field." While Lu Yan is improving his realm, breaking through to becoming a god and overcoming tribulations, he is also investigating the truth and fighting against the controller's chess pieces. In the end, he faced direct intervention from high-dimensional "players" and made a choice between protecting his homeland and pursuing the pinnacle of personal immortality, thwarting the conspiracy and reshaping the order of the earth.
