A sword slices away the camouflaged rock, and the smooth, blackened cut reveals a pleasant feeling. The heat of the sword body can be clearly felt in his hands, and although the operation to withstand the heat of his arm has not yet been completed, his physique allows him to use the pneumatic sword for a few minutes without any problems.

Having figured out the inner workings of the metal gate with sonic probes, Kasia carefully avoided the power lines that drove him, carefully cutting through its roots. The blade of the sword circled around the circular metal gate without the slightest hindrance, and the molten metal condensed into a strange shape at the cut in the next moment.

He had always been unhurried, as the dozen or so people at the steam furnace also seemed unflustered, and Kasia guessed that he was probably infected by their idleness. After waiting for more than half a minute, when the temperature of the solidified metal reached the range of the palm of his hand, Kasia spread out his hands, grabbed the incision directly, and slammed his fingers in, carefully lifting a gate and setting it aside.

It's very massive, and half of the door weighs about a ton and a half. Behind the door was a stone staircase that had been slowly carved out of the way, and it was only when the temperature of the pneumatic sword had dissipated that Kasia entered.

The "Fifteen 、、、、" lights pulled a straight silhouette on the stairs ahead, and as Kasia counted the number of people, he drew his revolver and made several nostalgic movements to change the bullets in the drum. It's been a while since I've used this powerful weapon.

There was no sound in his footsteps, and when he reached the end of the stairs, Kasia raised his revolver and turned the corner smoothly. In the bright light was a long alloy table the size of a conference table, water and a few weapons, and a few communicators with standby lights on on them. There were four people at the table, all doing their own business, mostly reading newspapers and magazines, except one who was wiping the parts of the disassembled musket.

The man wiping the parts of the weapon seemed to be aware of it, and within a fraction of the time he looked up, the sound of exploding gunfire had already stirred up the water in the water cup on the table into a circle that converged towards the center. Splatters of blood stained large swaths of the tabletop, and Kasia glanced at it, then focused on the reticle's crosshairs.

The real-time stats of the remaining eleven people were all fluctuating wildly in their heads, and Kasia still slowly turned her body and fired a shot at what appeared to be a wall of the lounge.

Rock fragments splattered, and a large hole was blasted out of the stone wall less than a few centimeters, followed by another bullet flying out of the hole, and the trilling sound echoed through the corridor behind the wall.

"Nine、、、 Cassia counted himself, and the servo-driven hand changed the bullet with the shortest route, the most precise movement, and the fastest speed. As the six bullet casings, still in a cloud of smoke, splattered on the ground with a crisp sound, Kasia turned and rushed forward to a door behind her.

The iron door was smashed open by the composite bulletproof plate almost at the same time, and several flashbangs poured in, detonating in the air, and the bright light flooded everything for a while. There was no effect on Kasia, because the eyes were closed, but the enemy did not know about the situation.

A man entered, half-footed into the break room. Holding a shield in his arm, the man had been squatting slightly so that his feet were protected by a bulletproof shield. He silently counted the time it would take for the flashbang to fade away, and when he opened his eyes and observed the rest room through the bulletproof glass window in his shield, a swarthy muzzle nearly twice the thickness of an adult's thumb was aimed at him. Then, the bright light of the flames from the muzzle of the gun made him subconsciously close his eyes again.

Without a chance to open his eyes, Kasia fired a single shot, his wrist slightly turning in response to the sonic detection, and fired four more shots in quick succession. It wasn't until the reverberation of the "bang" was suppressed by the "hum" of the steam furnace that Kasia stepped into the blood-splattered corridor on the walls, and walked along it as if exploring a labyrinth without the slightest difficulty.

"There are four more people, and the captain of the team here should be him. As if reading through the detailed instructions out of thin air, Kasia carefully bypassed the corpse step by step, bending down as he passed by, and felt eight steel-hulled bombs hanging from his waist. At this point, the remaining bullets were withdrawn, and Kasia reloaded the revolver.

The humming was rising, and at the end of the hallway was a wider cavern, with only the ground mounted on flat steel plates. On both sides of the mine, evenly spaced metal supports were erected against the concrete footing structure, and the red copper pipes, which were more than three or four times the diameter of an adult's waist, were heavily pressed on them.

Wrapped in thick, yellowed insulation, the perennial temperature keeps the mine in dry heat. There is a red copper pipe with a similar diameter on the left and right sides, and the others are less than ten slender pipes, only the size of an arm, nested in the gap between the main pipe and the bracket.

At the end of the corridor, reducer branches appear in various pipelines, and deep holes in different directions have been slotted out of the rock, and a dozen copper pipes of various sizes have been submerged into them, connecting to various parts of the mine's internal network, providing the necessary impetus for the rebels.

The cave is very deep, and after walking nearly 20 meters, the cave has been artificially expanded into a large cavity, about 30 meters long. The copper pipes are neatly arranged here, and the valves of different shapes are perfectly installed on the pipes. Although the level of control and control is not comparable to that of the Empire, Cassia, who is familiar with steam power, has to admire the high standard of assembly here.

The numbers on the pressure gauge fluctuate extremely quickly in a small area, and the hydraulically driven servo system moves finely and flexibly according to the real-time data provided by the differential machine, which is adjusted together with other mechanisms to maintain the stability of the steam output.

"I don't know if it's going to be the first bands of differentials to be eliminated in the Empire. Perhaps the operation of the various institutions within the entire mine is driven and controlled by an array composed of several zero-type differential machines. Kasia stood in the cavity for a few seconds, coming to a natural stop, and it seemed to be a normal reaction when she came across something she was interested in.

Taking another step, Kasia removed the two steel-hulled bombs from her waist and pulled out the tabs.

Footsteps instead of Kasia in the countdown, after the ninth step, Kasia selected a point, two steel-hulled bombs one after the other flew out in a calculated route and hit the rock wall of the mine, the great force made them bounce twice in a row, and then exploded.

A wave of air hit Kasia's face, and the smoke and dust quickly billowed up and filled a small section of the cavern. Knowing something, Kasia walked to the side, and a barrage of bullets pierced through the smoke, pulling out a dark red ballistic line and knocking out pieces of rubble from the rock wall not far away.

The bullets were always a step slower, flying not far from Kasia's body, passing through a cloud of air and hitting nothing.
