Infinite Synthesis Bar, the Goddess at the Beginning Came to Me to Ask for Elixirs

Lin Fan traveled through the parallel world and obtained an infinite synthesis bar. It allows two things to become more powerful after they are fused. This made Lin Fan, the owner of a small pharmacy, very ambitious! I, Lin Fan, must make a miracle medicine that even the First Emperor has not asked for! I, Lin Fan, want to refine the elixir of immortality! Ding dong, congratulations to the host for synthesizing the Essence Cleansing and Marrow Removing Pill! Lin Fan: "Can I live forever?" System... Ding dong! Congratulations to the host for obtaining the Muscle Relaxing and Bone Strengthening Pill! Lin Fan: "Can I live forever?" System... Ding dong! Lin Fan: "Stop it! Can you live forever?" System... Just when Lin Fan tried to synthesize it countless times and failed one by one, the goddess who insulted him as a quack and called him a liar yesterday appeared at the door again. I saw her speaking coquettishly: "Um, Divine Doctor Lin, your elixir from yesterday. Do you still have it?" This novel and its characters are purely fictitious.
