Time passed by little by little. It had been nearly four months since Zhao Hai arrived on the miscellaneous spirit continent. In these four months, Zhao Hai spent most of his time with the children. Now, he had taught them the most basic principles of botanist. Those children were now basically qualified botanist apprentices. As long as they went through a period of trial, they could become qualified botanists.
In the past four months, Zhao Hai had not only improved the quality of the mountain bean, which could yield 5000 kilograms per mu, but also improved the corn many times. He had also discovered several types of plants that could be planted. These plants were all food products, and their yield was much higher than the corn that had not been improved.
