It's Urgent to Save the Witch

(Wasteland + Witch + Magic Potion + Partial Farming) "I traveled through time and was adopted by a beautiful girl. This plot... Does it mean that I have come to a world of nooks and crannies?" "What does it mean to have a blood moon in the sky, world pollution, monsters rampant... Did I take the wasteland script? Fortunately, I awakened the Golden Finger of the synthesis table, which can pick up properties and synthesize them with all things. I used it to synthesize food that reproduces quickly and weapons that save lives." "What? The beautiful girl who adopted me is a witch who is hated and feared by the world? A group of people came and wanted to take her away. Have you asked about my big sword?" "What? Not only does the witch possess extraordinary power, but she can also create sequence potions through the synthesis table?" When Lin Ci stepped onto the surface, he knew that there were many oppressed witches waiting for him to redeem them in this wasteland. It's urgent to save the witch!
