"The gourd served as a bedroom for the night and held medicine, which Li dispensed with great beneficence to the poor and needy." Laozi also used the bottle to make him an iron crutch that would never rust nor break. He then told Li that he was ready to join the immortals. From then on, Li was tasked with curing the sick and he travelled to many lands and "could be found wherever the sick lay dying or the poor were persecuted."
