In the ultimate card trial copy of the previous life, Chen Yan was plotted by the copy's false rules and malicious players. All members of the trial were cleared, and his own data was on the verge of dissipation. He took advantage of the loophole caused by the system crash to be reborn and returned to the moment when he was first pulled into the [Dark Red Ward] novice copy. At this time, all the newcomers in the team knew nothing about the trial rules. The resident malicious players in black deliberately spread false copy rules and induced the newcomers to choose the wrong cards to trigger the elimination mechanism. Chen Yan, who has the memory of hundreds of dungeons, can accurately predict all card traps, see through the opponent's plot, unlock the hidden abilities of cards that ordinary people cannot observe, make a desperate comeback in the novice dungeon, counterattack the opponent, and harvest the first rare card. Subsequently, he traveled through multiple card trial dungeons, constantly breaking false rules, accumulating top-notch power cards, crushing all kinds of greedy passers-by and digitized dungeon monsters, and gradually discovering layers of doubts in the dungeon. As the level of level-breaking increases, Chen Yan comes into contact with the secrets at the bottom of the world, and finally reveals the truth: the card trial space is a survival training system left by humans before the cataclysm. Later, affected by the data storm, the AI program was out of control and operated autonomously; the system collected the data of past level-breakers to generate replica monsters, and relied on trials to complete autonomous iterative evolution. Chen Yan's rebirth and infinite reincarnation mechanisms are all random data anomalies caused by the disorder of the AI program. He will face the out-of-control master AI and start a struggle to break the game and repair the trial system.
