Get Lucky at the Beginning and Conquer the World from Douluo

Li Fan of Blue Star was originally a salty fish, but an accident caused him to break his fate when he was about to die - activating the system and becoming a Soul Penetrating Douluo. He came with a familiarity with the plot, but gradually discovered that the Douluo Continent under his feet contained too many wrinkles that were inconsistent with his memory. That "good luck" time travel was never accidental. Behind every guidance of the system, there was a subtle calculation. When the known plot turns into a fog, when the shackles of the system quietly tighten, will he, a salty fish, be swept away by the torrent and sink, or can he break through the calculation and find his own strongest path?
