Returning from the alien battlefield of mountains of corpses and seas of blood, the god of war Ling Xiao, who possesses the power of destruction, signed a marriage contract with the female owner of a folk shop who was on the verge of bankruptcy in order to suppress the rampaging godhead and repay his kindness. He chose to hide in the noisiest market and became an ordinary delivery boy who shuttled through the city. The electric car is his new mount, the mobile phone is a portable crystal, and behind every order, there is a tiny world waiting to be "healed": using holy light to relieve tenosynovitis for programmers who stay up late and working overtime, using elf recipes to improve beef noodles at street stalls, and using dwarf forging ideas to help old craftsmen repair heirloom iron pots... When aliens The pursuers from the world are tearing apart the space, and the National Security Anomaly Investigation Division also sets its sights on this small shop where "cultural miracles" are constantly emerging. Ling Xiao puts down the lunch box and says to the street behind him and the person who has cooked a late-night snack and is waiting for him to go home: "My new battlefield is this order with a 100% delivery rate - delivery, which is peace."
