Melting Sky Remaining Fang

People in the Nine Realms didn't dare to look up at the sky. A thousand years ago, someone melted a corner of that sky. The recipe is discontinued. The prescriptions for elixirs, utensils, formations, everything that said "how to make" were all turned into waste paper overnight. Later generations only regarded it as a natural disaster and lived on their knees for a thousand years. Lu Chuan, the handyman sweeping leaves in the medicine garden, was the only one who still raised his head. He touched the scratches on the broken tripod passed down from his ancestors that others could not see: Each of the three missing legs has its owner. Molten Sky is not a natural disaster, it is a fire lit by someone. He picked up the scattered remnants one by one. On the day when the three legs return to their original position, the hand that lit the fire will be pressed back into the furnace.
