Call of the Worlds: Conquer from the Doomsday World

In the doomsday world, human beings are lingering here, like a fire that will be extinguished at any time. Xia Hong came to this world and obtained a world summoning system. The drawing opportunities will be refreshed at midnight every day. Here he can extract everything that exists in the world, whether it is troops or items. Whatever you can think of, you can get it. And it just takes a little luck. His first summons resulted in the Terran infantry from the Warcraft game. He doesn't know what his future will be like, but what he wants most now is to survive.
