Lin Feng, a gourmet expert and master of agriculture who believes that food is the first thing and that science and technology can change destiny, crossed over to the Xuanyuan world where the lowest-level slaves of the medicine garden were the lords of the Chengdan Dao. He was accused of "cultivating heretics" and connected the two worlds with a black iron pot. With the support of the whole country of China, he created a new Taoist training system, overturned the ten thousand years of alchemy orthodoxy with gourmet Taoist food, and gradually built the Xuanyuan world into China's modern spiritual agriculture and animal husbandry base, and eventually led China to unify the heavens.
