I Kidnapped an Alien Civilization

One failed experiment. One billion lives hanging by a thread. When the advanced Pajero civilization attempts a dimensional leap, they accidentally bind their entire species to Li Mo—an ordinary Earth high school student. Every bruise he gets, every illness he catches, every year he ages brings them closer to extinction. Now this Type-4 civilization must do the impossible: keep one human teenager alive at all costs, while he holds the ultimate leverage over beings who can reshape reality itself.
