Chapter 1142: The flame that started to burn (9)

A sword cuts off the camouflaged rock, and the smooth black incision reveals a pleasant feeling. The heat dissipated from the blade can be clearly felt in the hand. Although Cassia has not yet completed the development of heat-resistant surgery on his arm, his physique allows him to use the pneumatic sword for a few minutes without any problems.
Using sonic detection to find out the internal structure of the metal gate, Cassia carefully avoided the power line that drives him and carefully cut it from its root. The sword body turned around the circular metal gate without any hindrance, and the molten metal condensed into a weird shape at the cut in the next moment.
It has always been in a state of calmness, because the dozens of people at the steam furnace also seemed calm, and Cassia guessed that he was probably infected by their leisure. After waiting for more than half a minute, when the temperature of the solidified metal reached the range where the palms could touch, Cassia spread her hands, grabbed the incision directly, buckled in with her fingers, and carefully lifted one of the gates and put them aside.
It is of great quality, with a half-side door weighing close to a ton and a half. Behind the door was a stone staircase that was dug down slowly. After the temperature of the pneumatic sword had dissipated, Cassia walked in.
"Fifteen people..." the light pulled out a straight silhouette on the stairs in front. When Cassia was counting the number of people, he pulled out the revolver, and did a few nostalgic changes in the drum neutron bullet. . It's true that I haven't used this powerful weapon for some time.
There was no sound from his footsteps, and when he came to the end of the stairs, Cassia raised the revolver, turning his body smoothly around the corner. Under the bright lights, there is a long table of alloy material the size of a conference table, water, a few weapons, and several communicators with standby indicator lights on. There were four people at the table, all doing their own things, most of them were reading newspapers and magazines, and only one person was wiping the parts of the disassembled blunderbuss.
The person who wiped the weapon parts seemed to have noticed it. Within a short period of time when he raised his head, the burst of gunfire had already stirred the water in the water cup on the table into a circle of ripples that gathered towards the center. The splashing blood stained a large area of ​​the tabletop. After seeing it, Cassia focused his gaze on the crosshair of the revolver.
The real-time data of the remaining eleven people changed crazily in their heads, and Cassia still slowly turned his body and fired a shot at the wall that looked like a lounge.
Rock fragments splashed away, and a large hole was exploded in the stone wall less than a few centimeters. Then another bullet flew out of the large hole, and the trembling sound reverberated in the corridor behind the wall.
"Nine people,,,," Cassia reported to herself, servo-driven hands used the shortest route, the most precise movements, and the fastest speed to replace the bullets. When the six shells still nesting in a ball of gunpowder splashed on the ground with a crisp sound, Cassia had turned around and rushed to a door facing him behind him.
The iron door was knocked open by the composite bulletproof board almost at the same time, and several flash bombs poured in and exploded in the air, and the strong light flooded everything for a while. It has no effect on Cassia, because the eyes are closed, but the enemy does not know this.
A man came in, half-footed into the lounge. With a shield in his arm, this man has been squatting slightly, keeping his foot under the protection of the bulletproof shield. He silently counted the time when the flashlight disappeared. When he opened his eyes and at the exact moment, he observed the situation in the lounge through the bulletproof glass window on his shield, which was almost twice the thickness of an adult's thumb. The dark muzzle was precisely aimed at his sight. Then, the bright light of the flame sprayed from the muzzle made him subconsciously close his eyes.
Without a chance to open, Cassia fired a shot, his wrist turned slightly following the sound wave detection, and fired four more shots in succession. After the "boom" reverberation was suppressed by the "buzz" of the steam furnace, Cassia walked into the blood-spattered corridor on the wall, and followed it, as if exploring a labyrinth with no difficulty. Walking gesture.
"There are four more people, he should be the leader of the team here." Cassia seemed to be browsing the detailed instructions out of thin air. He carefully avoided the corpse step by step. When passing by, he did not forget to bend down and touched eight steel shells. The bomb hung around his waist. At this time, the remaining bullets were returned, and Cassia refilled the revolver.
The buzzing sound is gradually rising, and at the end of the corridor is a wider mine, only the ground is placed with flat steel plates. On both sides of the mine, evenly spaced metal brackets were built against the concrete foot structure, and copper pipes with a diameter more than three or four times the waist of an adult were heavily pressed on them.
Wrapped with thick yellowing thermal insulation material, the temperature that escapes all the year round keeps the mine in dry heat. There is a red copper pipe with a similar diameter on each side, and the others are less than ten slender pipes, only the size of an arm, nestled in the gap between the main pipe and the bracket.
At the end of the corridor, different diameter branches appeared in various pipelines. The rock was also slotted into deep holes in different directions. A dozen red copper pipelines of different sizes were submerged in them and connected to the internal network of the mine. Everywhere, there is a steady stream of necessary power for the rebel forces.
This mine is very deep, and after nearly 20 meters, the mine was artificially expanded into a larger cavity with a length of about 30 meters. The copper pipelines are neatly arranged here, and valves with different shapes are installed on the pipelines. Although the level of control and control is not as good as that of the empire, Cassia, who is familiar with steam power, has to admire the high assembly standards here.
The numbers on the pressure gauge are fluctuating very quickly in a small range~EbookFREE.me~ The hydraulic power-driven servo system operates finely and flexibly according to the real-time data provided by the differential engine. This, together with other mechanisms, regulates and maintains the steam output. stability.
"I don't know which belt differential machine will be eliminated in the empire. Perhaps the operation of the various institutions within the mine is driven and controlled by an array of several zero-type differential machines." Cassia is empty. After standing in the cavity for a few seconds, he stopped naturally. When he encountered something he was interested in, it seemed to be a normal reaction.
Taking another step forward, Cassia took two steel bombs from his waist and pulled out the tab.
The footsteps replaced Cassia in the countdown. After the ninth step, Cassia chose a point. Two steel bombs flew out one after another in a calculated route and hit the rock wall of the mine. The great strength made them continuous Bounce twice and then explode.
The air wave hit Cassia's face, and the gunpowder and dust quickly rolled and filled a small mine. Knowing what, Cassia walked to the side at this time, a series of bullets immediately penetrated the smoke, pulled out a dark red ballistic line and shot out fragments of gravel flowers not far from the rock wall.
The speed of the bullets has always been a step slower, all flying past Cassia's body, passing through a patch of air, without hitting anything.
