Situ Wen laughed: "Instructor, do you remember the incomplete Mysterious Transformation Furnace you gave me? You once said that by combining the Mysterious Transformation Furnace with the mechanism, it can fly just by burning coal."
Chen Shi's eyes lit up: "You made it?"
Situ Wen nodded vigorously, yet somewhat bashfully, saying: "Our Lu Ban Sect originally couldn't make it, but with the help of the brothers from the Heavenly Court's Ministry of Industry, we slightly modified the Mysterious Transformation Furnace so that the mechanism can also fly by burning coal."
Chen Shi inspected one of the furnaces, seeing that the interior had various bright and thin lenses, but the talismans on the furnace's inner walls were different from before, indicating many modifications, even the sacrificial refinement method had changed.
"Can this really fly by burning coal?" he inquired.
