Doomsday Girlfriend: My Backyard Leads to Doomsday

Song Chao found a ring that allowed him to freely travel between our world and a post-apocalyptic world. In the post-apocalyptic world, food was more valuable than gold, and there wasn't much left in that world except for gold! Song Chao has found the way to make it big! He took a tomato from his refrigerator at home and sold it for ten kilos of gold in the other world! You can even exchange food for beautiful women! You really think you can do whatever you want when you can offer food after the apocalypse? Yep, as long as you can offer food, you really can do whatever you want! (Source: iQiyi, translated)
