The City Is Besieged by Strange Tides, I Awakened My Only Talent, Echo

Lin Yan never thought that an ordinary night study session for his senior year would turn into a hell on earth. Extraterrestrial creatures tore open space rifts, corrosive insects poured into Jiangcheng No. 3 Middle School, and the peaceful campus fell instantly. When his life was hanging by a thread, he awakened the only rule-based talent - Echo. He can actively activate the power of rules, but he must pay an equal price for his blood, spirit and even martial arts foundation. One thought immobilizes the insects, another thought ignores the defense, but every time he takes action, he overdraws the source of life. Disaster is just the beginning. Extraterrestrial creatures continue to invade, and the Armed Forces Administration, special teams, and hidden forces appear one after another. Lin Yan dragged his gradually damaged body and echoed again and again in desperate situations.
