If a Mortal Cultivates Immortality, I Can Turn Waste into Treasure

Protagonist: Lin Yi (traditional immortality + mortal flow + no system + turning waste into treasure + decisive killing + caution) A young man in a mountain village is blamed for killing his father and massacring the whole village. Breaking into the magnificent world of immortality, using the stone pendant that turned waste into treasure in his hand, relying on caution and decisiveness in killing, he went through Qi refining, foundation building, golden elixir, Nascent Soul... And walked out on his own path to becoming an immortal. (The gold finger stone pendant is not purification. It is a restoration of the state an item once had. The item must have experienced this state before it can be restored to this state. For example, a magic weapon that has failed to be refined. If the protagonist wants a good magic weapon, he must restore it to this state. I have experienced various materials before the official refining process, and started refining it because the magical weapon that failed to be refined has not experienced its good state. However, a magical weapon that was damaged due to fighting can be restored directly to its complete state.)
