Dimensional Invasion: I Became the Leader of Shuka

[Dimensional invasion + alien world + doomsday + decisive killing + violent troops] By chance, a god from another world discovered the coordinates of the Blue Star. However, due to the contract signed with the gods, the dimensional war could not be initiated by the god himself. Although he could not do it directly, in order to conquer Blue Star, this god indirectly used his divine power to destroy human technological civilization, rendering all kinds of electronic equipment and high-tech instruments owned by humans useless. Planes, cannons, missiles and firearms were all turned into a pile of waste. What's even more outrageous is that God directly erased all human information and books recording technology. Even the part recorded in human minds was erased. Humanity suddenly returned to the age of cold weapons. But the only exception is the protagonist. Due to system reasons, all the technologies produced by the system can still be used. The gods then launched a dimensional invasion and sent countless monsters to Blue Star, and the end began to come. See how the protagonist Liu Jun, the leader of Xiuka, navigates this doomsday world. Kill monsters, learn magic, create all kinds of monsters, recruit the Shuka Army to dominate the doomsday, and counterattack other worlds
