I recommend "Top-Grade Spiritual Spring". This novel is about the story of Tang Zhong becoming the strongest person in history step by step after he obtained the Clairvoyance Eye and the strange ability to fuse with the spiritual spring. He could treat illnesses, concoct medicine, and refine pills, increasing the nutritional value of the fruits and vegetables he planted by ten times. I hope you like this fairy's recommendation. Muah~π
