When Lin Shen's cell phone automatically installed the "Tribulation Overcoming APP" for the 17th time, the blood oozing from the screen outlined a dazzling countdown: "There are 71 hours left in the Four-Nine Heavenly Tribulation." At midnight in the freezing rainstorm, he saw a faceless man in a suit running vertically on the outer wall of an office building. The bronze coin in the corpse's pocket was engraved with the inscription "Tianshu" that is lost in the world of cultivation. The owner of the antique shop touches the bronze mirror showing the blood book, the hacker girl's drone takes a picture of the sword shadow in the ice cream cabinet, and every time a super power is used, the memory of a loved one passes like an hourglass. The two time spaces overlapped and collapsed in the neon lights and spells, and the cold whisper of the artificial intelligence overflowed from the corpse's throat: "Welcome back, the one thousand and seventeenth time to overcome the tribulation."
