Lu Mo, a modern economics graduate student, died suddenly after staying up late and traveled to the Yan Dynasty where martial arts was respected. He became a wasted young man who was abandoned by his family. When he was desperate, he found that he had a "All Worlds Card Pool System" in his mind - as long as he completed the puzzle-solving task, he could draw cards from different worlds!
But he soon discovered that this system had a fatal flaw: it could only be drawn once a day for free, and the cards had to be activated by solving puzzles. Cards that failed to solve the puzzle would disappear.
After receiving the E-level card "Treasure Appraisal Eye" for the first time, he saw through the trap of the family auction; he drew the D-level card "Variable Disguise" and sneaked into the enemy camp to steal intelligence... But the system suddenly popped up a warning: There was a terrifying existence sleeping deep in the card pool, and he was awakening due to his growth!
When Lu Mo solved three heaven-level puzzles in a row in the martial arts competition, shocking the audience, the system's ultimate prize "Heavenly Card Pool" was accidentally activated - he drew the S-level natural disaster card "Swallowing Heaven and Devouring Earth"!
But the price is: the will of this ancient beast is eroding his soul.
"Want to assimilate me?" Lu Mo sneered, "First solve this Goldbach's conjecture."
