Architect Kaelen Vance [ LitRpg/ tower survival/dungeon]

At 2:00 PM on a Tuesday, the sky turned to stone. The sun disappeared, the atmosphere sealed, and a message appeared in the vision of every living person on Earth — a rent bill for one hundred million Mana Coins, due in thirty days, with consequences listed in ascending order of extinction. While everyone else grabbed swords and staffed up for the apocalypse, Kaelen walked around the tutorial pedestals and found the seam in the simulation wall. The System, apparently deciding this counted as problem-solving, gave him something it had never given anyone else. The Architect class. Master of the environment. The battlefield is your weapon. No combat stats or attack skills. Just the ability to read any structure in the world and understand, at a molecular level, exactly which piece to remove to make the whole thing fall apart. It turns out that is enough. What follows is not a story about a hero who grows stronger until he can beat the final boss. It is a story about a man who treats every problem as a load-bearing calculation and slowly, painfully discovers that some loads cannot be calculated — they can only be carried. Floor 1 is of cold and darkness and a building full of people who did not ask to survive under his watch. The floors above are something else entirely.
