Infinite Rescue Operation

Yang Li opened his eyes and saw a huge elevator like a thermos cup. Only the top and bottom were black round unknown iron blocks, and it was surrounded by transparent glass. He could clearly see the various wars breaking out in the outside world. Why are there all kinds of wars? Because the elevator Yang Li is riding in is constantly shuttling. Every time he passes through a layer of ink-colored clouds, the battlefield in front of him changes. Sometimes there are machine guns and cannons, aircraft and warships, sometimes long bows and arrows, long iron armors, thousands of horses galloping, sometimes lasers are fired, and barrages hit the air. Some world wars were very similar to his world, while others were completely different. What he saw in front of him shocked his heart, and he was speechless for a long time. He just looked at the chaotic world outside. The elevator passed through the clouds again and stopped in a brightly lit room. The door opened with a click, and a soft voice came: "Newcomer, Yang Li, number 5242, your mission is to survive." This novel and its characters are purely fictitious.
