Above the Great Dao

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.

Chen Tang walked over and said: "Burning coal is possible, but it requires activating the mechanism to transmit power; three thousand catties of fine coal for one incense stick's time. Using a cultivator's mana is also feasible and more convenient, but the mana consumption is enormous."

He summoned one of the furnaces, the talismans on the furnace walls instantly became bright, reflecting off the lenses, which began to spin, and with a swoosh, a sword light as fine as a hair suddenly spurted out from the furnace mouth!

Chen Shi was astonished: "Xuanwei Sword Qi?"

Situ Wen smiled and said: "Old Master Chen slightly modified the talismans of the Mysterious Transformation Furnace."

Originally, the Mysterious Transformation Furnace would emit various forms of True Qi with great power, comparable to a full-force strike from a Divinity Transformation Realm or Divine Descent Realm cultivator, but after Chen Tang's modification, the talismans on the furnace walls became Xuanwei Sword Qi talismans. Illuminated on each mirror, the mirrors rotated around the furnace wall, and with each rotation, various Xuanwei Sword Qi would fly out from the furnace.

The spurted sword qi was not long, only about three inches, extremely thin, but at about a zhang from the furnace mouth, it would enlarge, becoming nearly a foot. At two zhangs, the sword qi would expand to three feet.

Moreover, the number of sword qi spurted from the furnace was large; the faster the mirror rotated, the more sword qi spurted!

Chen Shi also summoned a sword furnace, mobilized his mana, and injected it into the furnace. Over a thousand mirrors inside the furnace rotated, and instantly, streams of sword qi spurted from the furnace mouth. A great force struck, pressing the sword furnace downwards!

Chen Shi held the sword furnace with both hands, reinforced his mana, and instantly, the sword qi in the furnace pierced the sky, forming a sword qi torrent miles long, shooting straight into the sky!

A huge pressure came through Chen Shi's arms, pressing his legs into the earth.

He continued increasing his mana, and suddenly, with a rumble, the ground around him caved in, creating a pit four to five zhang wide!

Chen Shi was shuddering under the pressure and slowly withdrew his mana. The frantically spinning mirrors in the furnace gradually slowed, and the torrent of sword qi spurted from the furnace mouth also gradually subsided, and Chen Shi only felt the pressure decrease.

Finally, the mirrors in the furnace stopped spinning, and the sword qi dissipated.

"What a great thing!"

Chen Shi put down the sword furnace and praised, "It's truly a great thing! If this is mounted on the mechanism, it might even fly to the outer heavens! But the consumption is huge; even with my mana, I can't sustain it for long!"

The cultivators from the Heavenly Court's Ministry of Industry installed the assembled sword furnaces onto the mechanism, with a total of eight sword furnaces.

The mechanism's structure was not dead weight; inside were hidden force transmission mechanisms, and the central part contained a massive pill furnace, where many Lu Ban Sect cultivators were transporting coal into the alchemy furnace room.

Wu Qingyu brought Huo Dou, speaking in soft tones to soothe this half-demon, half-Ghost God giant, extracting some black dog blood from it for the Red Mountain Hall talisman masters to sketch the talismans on the mechanism.

Chen Shi inquired: "What are you preparing the mechanism for?"

Wu Qingyu replied: "To fly to the outer heavens and see what exactly went wrong with the Outer Heaven True God! We need to save ourselves."
