Lin Han, an outer disciple of the Qingyun Sect, has a withdrawn and cold personality, but has a sincere heart that he does not want to express. During the entrance test three years ago, he was found to have mediocre qualifications, and has become the object of ridicule since then. However, no one knows that there is a "card-drawing system from all realms" hidden in his body from ancient times - as long as the system tasks are completed, various God-defying cards can be drawn: Kung Fu cards, elixir cards, magic weapon cards, and even summoning cards!
By chance, Lin Han drew an "Insight Card" and accidentally discovered the secret of the collusion between the sect elders and the demons. What shocked him even more was that this elder was the traitor who betrayed his sect and killed the previous sect leader - Chen Xuanji! Chen Xuanji has been lurking in the sect for many years, secretly cultivating forces in an attempt to seize the sect's most precious treasure, the "Tiandao Stone".
Facing powerful enemies, Lin Han relied on the system to continuously become stronger: drawing cards to obtain the "Nine Revolutions Mysterious Skill", summoning ancient sword spirits, refining god-level elixirs... He exposed Chen Xuanji's conspiracy step by step, and grew from a waste looked down upon by everyone to a hero who turned the tide. However, as the level of card drawing increased, Lin Han discovered that there was a bigger secret hidden behind the system...
