I Have Countless Elixirs

Ye Changtian's ascension failed due to a sneak attack. He was struck by a thunder curse and his immortal body was completely destroyed. He only had twelve years left to live. Three hundred years before his rebirth, his left arm was taken away and he was poisoned by a villain, which caused his cultivation to regress and his family to be destroyed. Accidentally awakening the [Tai Shang Alchemy Furnace] system, all the elixirs you refine are elixirs, and all you forge are divine swords. In order to return to the immortal path, Ye Changtian worshiped in Qiyun Holy Land and entered the elixir to break through the realm. A crane bone flute is in hand, triggering "thousands of cranes coming to court", and harvesting the mount [Red-Crowned Crane]. He just wants to concentrate on training, kill his enemies with his own hands, rebuild his immortal body one day, and then ascend to the immortal path! Unfortunately, the journey was bumpy and troubles came one after another.
