Without Realizing It, I Became the Leader of a Fallen Civilization

Zhou Xiao, a young man from Earth on some unknown timeline, is swept into a dimensional war between the Atlantean Civilization and the Soul-Devouring Insect Swarm. By chance, he gains high-level access to the Atlantean Civilization. From then on, he gets to command a super-civilization with a wave of his hand and trample the savage insect swarm beneath his feet.

The soul crosses dimensions, while the body will eventually shatter. Immortality is the ultimate pursuit of all intelligent life. Between cycles of reincarnation, there is no good or evil, only the resolve to press forward or fall behind.
