The high-pressure tank exploded, and the high-pressure and high-temperature gas inside erupted, and the impact force formed by the short moment caused the entire surrounding factory to be destroyed. Aside from those huge load-bearing pillars, there is nothing standing upright on the pictures of the scene. The center was flattened with traces of fluid from the strong winds. The wreckage of the high-pressure pipe broken from the middle and lower part fell there. Countless iron sheets and steel bars were piled up on the edges, like a crater, enveloping the wreckage in the middle.

A trail was opened on the pile of debris by large construction machinery for technical exploration personnel to pass through. The photograph was also taken from the outside of the trail and roughly captures the full picture of the high-pressure canister.

The walls of the high-pressure tank were two palms the width of an adult's palm, and the exposed fracture zone was instantly polished smooth by the impact of the explosion, but the marks still looked hideous.

Technical explorers said that the service life of the high-pressure tank had long since passed, and that it had left an old scar after being hit by large machinery due to the operation errors of the workers in the past. Later, it was only a simple welding of steel plates to strengthen the local bearing limit, and the problem could not be dealt with systematically, which caused this huge explosion accident.

But Kasia saw something else in the color photograph, a few scars of friction. It may have been caused by the collision when it fell, but Kasia himself preferred that it was the mark of a bullet. The most common traces of platinum bullets.

It's a shallow pit that isn't very big, not deep, like a dimple on a face when you smile. In some places even just faint white marks, the strength and toughness of the high-grade alloys, and the cylindrical body of the high-pressure tank itself, give it such resistance.

"Maybe you need to go there in person. Kasia put down the newspaper and walked to the window again. The site of the accident was some distance from the steam tower, but the light was as light as it was around the rotunda. Opening the cross pupils, you can still catch the hazy shadows of the various large processing machines there through the mist.

"The time is just right, Ye Jielin came here to collect the basic information, and then went there, just right. Did you meet Sotagan, and then there was a fight? It was a factory, and it was in line with the purpose of Sotagan coming here. "And even though the high-pressure tank has great strength, it is not impossible to destroy. Normal platinum bullets can't do it, but blue silver bullets do, and the attack doesn't have to pierce the high-pressure canister. As long as you continue to attack a point, a few bullets can be inserted into it, and you can create a crater that satisfies the strength and toughness of the destruction there. After the integrity is destroyed, the huge pressure inside will naturally quickly find this breakthrough. ”

Kasia carefully considered whether things would go this way, but there were no more clues, and no matter how much he thought about it, it was only a possibility that he thought it would be.

"Wait until late at night, or go over and actually do a survey. Kasia looked deeply at the accident site and muttered.

After about an hour, the lights in Kasia's room went out, blending into the light-infested darkness outside the window.

There were still a few trains working late at night, all of them vehicles transporting goods, and steel parts wrapped tightly in rainproof cloth on top of the iron shelves. At this time, all the passenger trains are resting at the main stations.

Away from the steam tower in the middle of the city, the bustle and temperature around it were swallowed up by darkness.

Kasia jumped on a freight train and made her way to the accident site. On the first carriage behind the front of the locomotive, the powerful triangular searchlight in front of him illuminated the cold two rails of the railway, and the reflected light was a little whiter than the cold moonlight overhead.

There were no people hanging out around at all, and the sound came from the factory that would not stop working. The loud crashing sound of the forging press and the "sizzling" sound of red-hot steel entering the cooling oil when it is quenched.

The freight train moved slowly through the city, and it took more than half an hour for Kasia to reach the outside of the accident site, where the lights had dimmed a little. A temporary iron wall was erected there, with a triangular iron frame supporting the base, and the height of the three meters was visually measured, enclosing the accident site. Only a large opening has been made at the original exit of the factory, and several carrier trains are parked on the tracks not far from the door, and clamping machinery is dumping steel scrap into the train cars that has been torn apart after the explosion and is ready to be transported to the smelter near the mine outside the city.

Kasia tried to climb onto the roof of the factory next to her, and the alienated weight was indeed a problem now. The roof gives you a better view of the inside of the protective wall. There are still many workers working night shifts at the scene, and the wreckage of the building around the high-pressure tank has been removed from the half. Now more people are using welding and cutting machines, working overtime to cut high-pressure cans that have fallen to the ground.

"It's late. Kasia crouched in the darkness of the roof, helpless. It was from that fault zone that the cutting site began, and now a small part has been cut, and all valuable traces have been turned into boxy alloy plates that have been removed.

After observing for a while, Kasia identified the workers one by one, perhaps including Sotagan, or Ovilla's henchmen. As the most "lively" place in the recent past, no matter who comes here, even if they know that there will be enemies hiding here, they will definitely come and take a look. The same is true for Cassia herself, as this is where clues and traces are most likely to be provided. But there was still some disappointment, or maybe the disguise of those people was so good that Kasia couldn't see the flaws. Kasia did not find anything unusual among the workers.

Sure that there was nothing of value left here, Kasia moved and was about to leave, when his half-crouched body suddenly disappeared into the darkness again, motionless, his heartbeat and breathing dropped rapidly at the same time, and his breath was gradually blown out by the night wind. Not far away, under the three-meter-high tin corner, something like a wild cat seemed to be roaming.

In Kasia's eyes, the darkness deepened. Something was absorbing most of the light, turning the moving object into a darker shadow in the black, now clinging to the corner of the wall and moving silently in the direction of leaving here.

When the shadow was a few dozen meters away from him, Kasia dropped from the roof of the factory, melted into the black air, and quietly followed the shadow.
