Zhao Yi was a Qi Condensation Level 7 cultivator and also at the 9th Layer of Body Refining. Coupled with his top-grade spiritual weapon, the Tianxing Sword, digging a stone cave was naturally a breeze. In the span of an hour, Zhao Yi had dug out two caves: one for alchemy and one for resting.
For the alchemy cave abode, Zhao Yi even installed a stone door that could only be opened using spiritual power. Later on, he would also need to set up a formation to isolate Divine Sense; after all, alchemy required an absolute quiet environment to avoid outside interference. For now, however, it should suffice.
It wasn't as if having an alchemy room, an alchemy furnace, and a pill recipe meant one could immediately start refining pills. In fact, there were still many things to do. For instance, the selection of spiritual herbs, the proportioning of ingredients, the source of fire needed for alchemy, the alchemy techniques, which herbs should be put in first and which ones later, and finally how to fuse the medicinal liquids—every single step had to be completely error-free. This was meticulous work, and anyone impatient shouldn't even think about trying alchemy, as no pills would ever be successfully refined that way.
