Song Changsheng was not entirely sure whether the cultivators of the former Treasure Bottle Sect could use spatial storage artifacts on the island, but generally speaking, an independent Alchemy Hall like this would usually have a Treasure Vault specifically for storing spiritual herbs and finished medicinal pills.
Even a Hidden Sect had to deal with the outside world. There was no way they could carry so many precious medicinal pills and Spirit Plants on their person at all times.
Perhaps the Alchemist had fled after the Heavenly Tribulation descended, which was why there was no corpse. But since they had not even bothered with the pills inside the pill furnace, they probably had not had time to take away the inventory. The barrier and restrictions were intact, so he should not come up empty-handed.
Stepping into the rear hall, he found it equally disordered. Jade Slips from the shelves lay scattered across the floor. He casually drew over one scroll and found that it was an Alchemist's pill-refining notes from before death. Everything was recorded in meticulous detail, from the temperature of the furnace fire to how the medicinal pills changed at different temperatures, even the state of the mist that dispersed when the furnace was opened.
Song Changsheng also kept notes after refining artifacts, but they were nowhere near this detailed.
It was clear that this had been an Alchemist rigorous to the bone.
"[Jade Clarity Pill]... He was actually a fifth-tier mid-grade Alchemist."
He picked up several more scrolls. Without exception, they were all pill-refining notes. Many of the medicinal pills were names he had heard for the first time, but based on the effects recorded in the notes, he could recall pills with similar effects. They were probably Pill Recipes created by the Treasure Bottle Sect itself.
