In a wasteland where clean water and land are monopolized by companies, Lu Ze is just a water plant maintenance worker struggling to survive. A fatal accident allowed him to awaken the ancient "Shen Nong's Rejuvenation Technique". The green light in his palm could heal radiation injuries and revive dead soil. When thugs from the monopoly company came to collect taxes and everyone fell into despair, Lu Ze set up a stall at the entrance of the shelter. The steamer was opened, and the white steam mixed with the aroma of wheat filled the air - his first batch of steamed buns was ready. From then on, the warmest smoke rose from the wasteland. This is a story about how he used a mouthful of hot soup and a steamed bun to heal his wounds, fight against monopoly, and rebuild his small home in the apocalypse.
