The Tide of Mutants Besieges the City, and I Awaken the One and Only Echo Talent

Lin Yan never imagined that an ordinary evening study session in his final year of high school would become a living hell. Extraterrestrial creatures tore open spatial rifts, and Corrosion Bugs poured into Jiangcheng No. 3 High School, instantly bringing the peaceful campus to its knees.

With his life hanging by a thread, he awakened the only rule-type talent: Echo.

He could actively wield the power of rules, but had to pay an equivalent price in blood and qi, spirit, or even his martial arts foundation. One thought could freeze a swarm of bugs; another could ignore all defenses. But every time he acted, he drained his life force.

The disaster was only the beginning. Extraterrestrial creatures continued to invade, while the Martial Administration Bureau, special squads, and hidden factions appeared one after another. Dragging his increasingly damaged body, Lin Yan echoed the rules again and again in the face of despair.
