A mutated crop plant growing in Unit 16-7 of Building 7. After the crystal core's energy was absorbed, the millet grew rapidly like a weed into a small tree filling the room with heavy seed heads hanging in clusters. A spider plant processes the millet heads into grains for long-term storage. The mutated crops including millet, potatoes, peaches, and kumquats have healing properties that can restore the human body, as evidenced by Zhang Dongxuan's back pain disappearing after eating them.
