Eren Kain was an ordinary engineer and inventor until the day the Tower of Trials appeared. A massive, otherworldly spire reaching into the heavens, the tower beckoned humanity with promises of power, wealth, and immortality—but also death. Unlike the others, Eren was forcibly bound to the Tower. No one else could enter until he began his climb, and he couldn’t leave unless he reached the top. Stripped of magic, aura, or any supernatural ability, Eren’s only advantage is his engineering genius and the technology he can smuggle in. From basic firearms to drones and exoskeletons, he uses every tool at his disposal to survive the monsters, traps, and bizarre ecosystems within the Tower. Yet even technology has its limits in a world governed by magic. As Eren climbs, he discovers the Tower isn’t just a trial but a puzzle. Its magic isn’t arbitrary—it’s systematic, a science he slowly learns to decode. However, one wrong calculation could kill him instantly, forcing him to balance experimentation with survival. He scavenges magic crystals, artifacts, and spell books, using them in crude, improvised ways to bolster his arsenal. Over time, he begins merging technology and magic, creating unique hybrid tools to overcome the increasingly insurmountable challenges. But why was Eren chosen? What secret does the Tower hold? With no escape and the weight of humanity’s fate on his shoulders, Eren must climb—not just to survive, but to unravel the truth of the Tower itself. every 50 collections I’ll give a chapter and every 20 powerstones I’ll give a chapter every 10 reviews I’ll give a chapter
