Immortality starts from the liver proficiency

Chapter 148 Show off your skills
The thunder of nine layers of gears meshing together could be heard from underground, and the gate of the Tiangong Fortress suddenly descended and turned into a ship bridge.

The most shocking thing is that the main body of Guniu Mountain is separating from the base, and the exposed sixteen-legged spider mechanical legs are hundreds of feet long. The heat dissipation slots at the leg joints spew out sulfur steam, dyeing the night sky within a radius of ten miles red!
The entire Tiangong City was lifted thirty feet under the support of the spider legs. The steam turbine originally buried deep in the foundation was fully revealed. Sixteen sets of circular boilers forged from black steel at the bottom formed the power core, and each was connected to a black steel transmission chain that was strong enough to drag the city tower.

The bonfire camp of the Incense Sect, which had been stationed outside the city, suddenly erupted in commotion.

The Night Watchmen looked in horror at the mechanical city that had occupied it for nearly a thousand years, which was now like a giant steel spider shaking off the dirt on its body.

"Then what is that?!!"

The Grand Master Xisui, who served as the chief protector of the Xianghuo Sect, looked up blankly at the mobile fortress heading towards them.

Those lousy blacksmiths who used to practice evil ways actually built such a terrifying moving city.

The eight spider legs do not simply move forward alternately, but follow the walking directions of the wooden ox and flowing horse passed down by the Mohist school.

Every step he took was done to precisely avoid the underground river. When the composite shock absorber at the end of the steel foot bloomed, it actually converted the downforce into propulsive potential energy, blasting out eighteen circular air waves behind him.

Xu Yunfan lay on the observation hole in shock, watching the towering steel city like a mountain rolling across the wilderness river under the moonlight.

Those pavilions and towers that were once regarded as landscapes have now all shrunk into combat modules. The Xuangang Fortress extends out with honeycomb-shaped arrow and crossbow armor plates, and deep gun muzzles protrude from the gaps.

"Release the Red Scale Fire!"

The roar of the Red Eyebrows guardian of the Xianghuo Sect was drowned out by the loud noise of gears meshing.

Hundreds of trembling Xianghuo Sect soldiers just raised the red phosphorus cannons that had just been delivered from Yujingzhou.

Suddenly, three thousand six hundred blade wheels flipped out of the Tiangong City Wall, and the black steel bricks were reorganized into a thousand-petal iron lotus under the push of steam.

The boiling quenching liquid gushed out from the lotus heart, covering the Xianghuo Sect's vanguard camp with red iron slag.

There were cries and wails, and it was a mess.

But it was covered by the huge roar of the Tiangong Fortress moving.

The clanging sound of broken chains came from deep within the earth's veins, and sixteen black steel spider legs, like mountain-supporting pillars, pierced into the rock layer with a loud bang.

The entire Guniu Mountain completely collapsed in the steam and sparks, and as the underground lava rose into the sky, it was accompanied by a mobile black steel fortress stretching for three miles.

"How does it feel?"

Zhan Yan folded his arms and looked at everything in front of him with shock.

"When I first arrived at Tiangong Cave, I learned that the entire city could be moved, which seemed unbelievable. The ancestors and disciples of Tiangong Cave have painstakingly built it for this moment."

After a long time, Xu Yunfan withdrew his gaze. Until now, his emotions have not calmed down.

It's too exaggerated!
"Tiangong Cave also has magical weapons."

Zhan Yan said this lightly, which made Xu Yunfan's heart move, and he remembered the black shadow under the thunder and fire pool when he was forging the black steel receiver a few days ago.

Subconsciously looking at the Tiangong Fortress under my feet, I wondered if it could move such a huge city. Was it forged with divine weapons as its core?

There is a related record in the Tiangong Forging Record in Tiangong Forging Art. It is said that a great Mohist master once built a movable fortress with his own hands, but it was not as large as the one it is now.

At that time, it was still an era when the Yuan Ling seemed to have disappeared but had not yet disappeared, and the secret power was about to cease, and there were still quite a lot of extraordinary secret powers existing in the world.

This huge Tiangong Fortress is almost entirely made up of a 99% mechanical transmission structure, plus the painstaking work of the civil engineer.

That night, the entire Tiangong Cave fell into a state of sleeplessness. The construction of the Tiangong Fortress, which took a thousand years to complete, naturally had extremely complex and numerous problems.

"The wind pressure in the Xun position is abnormal!"

"The impeller in the furnace can't withstand the fire. Quickly ask the Ministry of Works to replace the impeller in the furnace!"

"The drive shaft in the Xu area is overloaded!" Han Qiushan, a deacon from the Mechanical Hall, was shirtless and covered in grease. His roar was accompanied by the sound of metallic friction. "Soak the spare bearing in weak water coolant!"

"..."

Such a large mobile fortress requires an inordinate amount of maintenance. Once it is put into operation, thousands of problems are exposed. Almost all the disciples in the Tiangong Cave have to go into battle, and even the forgers in the Casting Hall have to help.

Xu Yunfan was naturally excited to see the prey and couldn't help but take action. With his knowledge of Tiangong forging, after he got started, his attainments would naturally be much deeper than those of ordinary disciples of the Machinery Hall.

Xu Yunfan walked through the steam-filled corridor, his ears filled with the hum of gears and the shouts of his disciples.

He stopped in front of the transmission shaft in the Xu area. The three-meter-wide black steel shaft was making a harsh friction sound, and the surface was turning red due to overload.

Xu Yunfan couldn't help but sigh with emotion. According to the quality of the black steel, as long as it was combined with a highly skilled weaponsmith, it was entirely possible to forge a low-grade sharp blade-level weapon.

Tiangong Cave has been located in Guniu Mountain for thousands of years. There is not much in the three-hundred-meter-long mine, but the black steel is almost becoming a common sight.

Before leaving, the disciples of Rongjintang specially sealed the mine, hoping that they would have the chance to come back in the future.

Several disciples from the Mechanical Hall hurriedly immersed the spare bearing in weak water coolant, but the cracks in the shaft core continued to spread, causing Han Qiushan to break out in cold sweat on his forehead, and a large area of ​​his clothes on his back was wet with sweat.

"Weak water can only delay the weakening of metals, it is a temporary solution, not a fundamental solution."

Xu Yunfan suddenly spoke, stroking the surface of the shaft with his fingertips.

The Thousand Machine Deconstruction special effect of the Heavenly Craftsmanship Forging Technique was activated, and the flow of the transmission structure inside the shaft core appeared in front of his eyes. He frowned slightly. The shaft core structure inside was messed up by the overloaded impact, like a group of entangled snakes.

If it continues, one of the spider's legs may temporarily stop functioning.

"Brother Xu, this axle is part of the 'Four Symbols Mountain Guarding' structure left by our ancestors. We dare not move it without permission!"

A disciple was so anxious that he was sweating profusely, and then he looked at him with horror.

Xu Yunfan had already picked up the Thunderfire Kirin Hammer, and the hammer head ignited the jade-breaking power of melting gold and forging iron, and smashed it hard at the mortise and tenon at the connection of the shaft.

"You are crazy!"

Han Qiushan rushed over roaring, trying to stop it.

Sparks flew where the hammer fell, and the shaft, which was on the verge of collapse, actually let out a clear dragon roar.

The crack was actually forcibly healed by this hammer, which made Han Qiushan pause and he couldn't help but slow down his steps.

Xu Yunfan pressed the shaft with both palms, his arm muscles stretched, and his cuffs became tight.

As the Black Turtle Camel Mountain's energy exploded, a very peculiar force of stacked armor spread along the palm, directing the violent shock force into the underground of the corridor bridge.

As the wolf spear creaked, the heat from under the shaft quickly faded away.
