Nobel-nominated agricultural expert Chu Jun crashed his plane and ended up on an uninhabited island. The system in his hand gave him super grain seeds, which could be grown in both saline and seawater. The rice yield started at 3,000 kilograms per mu. A storm at sea swept Ying Zheng, Meng Yi, and Wang Ben, who had gone to sea to seek immortality, to the shore. The three devoured potatoes and rice, and asked about the yield of grain seeds. They were shocked when they learned that the yield per mu was four to five thousand kilograms. Chu Jun only felt that the three of them were obsessed with filming, but Ying Zheng was convinced that this was Penglai Fairy Mountain, and Chu Jun was a reclusive immortal who wanted to use the emperor's gift to obtain high-yielding crops and eradicate famine among the people of Qin.
