Residual Furnace

Five hundred years ago, Alchemy was at its peak. At that time, all the alchemists in the world respected him as "Qing Nang". Legend has it that the elixir made by Master Qingnang can make dry bones grow flesh, and can allow dying people to live for another five hundred years. Among the four tribes of Taoism, demons, monsters and humans, who among the practitioners has never asked for a pill from Qingnang Sect? In the spring of that year, all the alchemists from all over the world gathered at Qingnang Mountain, saying they wanted to make the largest alchemy pot in history. Then the sky fell. No one can say exactly what happened that day. I just remember that when the alchemy furnace caught fire, half of the sky burned red. The fire burned continuously for three months, burning up every plant and tree in Qingnang Mountain, and also burned up nine out of ten of the inheritance of alchemy. When the smoke and dust settled, there were only a handful of alchemy masters left alive, and the only elixir prescriptions that had been handed down were the popular ones such as Qi Gathering Pill and Bigu Pill. That disaster, later people called it—— "Elixir Tribulation". As for what kind of elixir was refined that day, why it was refined, and whether it was completed or not, no one can tell clearly. It's just that occasionally an old alchemist will say when he's drunk: That furnace pill actually didn't explode. That furnace pill is done. What has become? No one knows.
