On the third day of time travel, the system has not been activated yet. My daughter-in-law, Shen Qingxue, was forced by the clan to take over the position of head of the family. I squatted at the entrance of the alley, picked up tree branches and drew circles. The housekeeper asked me what I wanted paper and pen for, and I said I wanted to write down a recipe. In this world, trauma medicine is extremely ineffective, and half of the people die from wound infection. I picked up the pen and dipped it in ink: I changed it to a hemostatic powder, which would be enough for the Chen family to eat several pots.
