Myriad Realms Dungeon: I Drew the Eight-Nine Arcane Art from the Start

【The rating just came out and will rise later, so read without worry】 【Reborn】+【Infinite Flow】+【No Female Lead】+【Decisive and Ruthless】+【the Myriad Worlds】 Jiang Xuan woke up Reborn, thinking he could use his foreknowledge to reach the pinnacle of life. But then, staring at the swirling, rainbow-colored vortex in the middle of the school field, Jiang Xuan was utterly confused!!! Rebirth? No! Dungeons from the Myriad Worlds had descended, forcing humanity to evolve! Even more outrageous, while other people got D-rank beginner dungeons, he was directly “bound” to a divine-grade dungeon! No golden finger, just a 24-hour countdown to death! His brain was forced to evolve beyond its limits, his senses mutated, and his strength awakened, at the cost of his body being liable to collapse at any moment! “You want to dissect me for research? You want to use me as a pawn? Ask the great halberd in my hands, and this brain of mine that's about to explode, if they'll agree!” From a clueless high school student to someone fighting to survive while powerful forces hunt him down, watch Jiang Xuan carve his way through the Myriad Worlds in this crumbling world, seize the key to evolution, and drag the lofty players who think they're in control right off their pedestals!
