I'm a Rookie in the Reincarnation Tower, and I Slaughter My Way Through Five-Star Apocalypse Dungeons

The Tower of Reincarnation descends upon Earth, tearing apart the ordinary order of life and forcing everyone into a deadly game of trials. Su Yue, who transmigrates into this world, casts off the original owner's bookish obsession with rote learning. Rather than rush into danger, he spends thirty years mastering every secret of the Tower. In his first beginner instance, he crushes his arrogant fellow player Yang Wei, recruits the swordmaster Saeko Busujima, teams up with Shizuka Marikawa and Rika Minami to form the strongest squad, uncovers the truth behind the T-virus, and prevents the EMP catastrophe. With absolute control over the plot, he rises to the pinnacle of the Tower's lower levels.
