The construction time of the Black Castle is different from that of Brino. It is a landmark building built after the rise of Brino. The underground waterway below still has a brand-new smell. There is not much rain here. The piece of pasted concrete above the head looks like
It looks like a freshly dried concrete block.
The beam of a strong flashlight hit one side of the waterway. The color of the concrete there was a little lighter than the surrounding color. It was added later. The difference was very obvious in comparison, showing the shape of a gap. This was only re-painted later.
Another blocked waterway line.
Cassia tied a strong flashlight to her waist, took out the small shovel she had prepared in advance, and determined that in this long waterway, except for herself and the running mice, there were no other people.
Finally, he began to knock out small grooves along the shape of the gap.
This is to place the small craters used for timed explosive bombs. After discussing with Lina in the morning, Cassia decided to choose the aspect she is most familiar with and good at as the breakthrough point for this mission. Their current plan only lacks the necessary elements.
Chaos, in order to ensure that the actions at the party can proceed smoothly, Cassia still felt that he had to add something to them. Putting all the possibilities on others, both he and Lina felt uneasy.
So after the discussion was completed, they started from the small hotel and went to the Exchange Building first, bought Blino's detailed underground waterway map and drawings, and then rushed to the Black Castle. There was still plenty of time. And this road was halfway built because of the
The water channel that was forced to be abandoned due to the complete problem of Black Fort was discovered on the way here.
The Black Castle is the largest and most luxurious hotel in Brino. The people they receive are either the small leaders of a certain force or the big financiers who come here from the gray zone or the empire. The original designer planned to connect the underground sewer directly.
Under the Black Fort, it is convenient to discharge domestic wastewater every day. However, considering that there is such a big safety hazard buried underneath, and anyone can drill in through the water channel, the design was changed, and the water channel of the Black Fort was designed as
It is in a semi-independent state, with only one interface to the urban waterway network system, and people are assigned to guard it in terms of security level. It is almost impossible to break through without being discovered.
This abandoned line at the time was only half-built. According to Cassia's estimation, the length may only reach the periphery of the Black Castle Hotel, but not close to the core area.
But this was enough. Cassia just wanted to use the sound of explosives and local vibrations to create chaos, or to create opportunities for those who were opposed to the Imperial Mining Company and the Three Primary Colors Group. He did not think about blowing up
Sinking the entire Black Fort. He may have had this idea in mind, but the amount of explosives he bought from the trading building was completely insufficient.
Lina is responsible for exploring places that are different from those on the panoramic map, as well as observing the number of security personnel around the Black Fort and the station, roughly judging their strength, and choosing the most suitable route to escape at night.
The pit was quickly dug, and Cassia adjusted dozens of timed explosive bombs to the same time and stuffed them all into the groove.
Hiding on the side not far away, he looked at his watch and saw that the hour hand pointed to half past one.
"The square above must be very lively." Before the last note of the sigh could be heard far out of the waterway, more than a dozen directional explosive shells on the side made a loud sound on time, and the muffled sound was continuously compressed in a narrow range.
With the increase, Cassia felt that a layer of misty air had gathered in her ears, and the sound became quieter.
The square above the waterway has been occupied by a lively crowd. Blino is built on a gentle slope. The underground waterway has a staircase-like structure and is deeply separated from the ground. The weak movement below is completely buried in the hustle and bustle.
The voice did not attract even a single person's attention.
The fat rats did not lose their nimble speed and flew through the waterway, far away from the explosion site.
When the light turned on again, all the rats squatting there ran away. Small pieces of blown concrete fragments spattered out and landed on a pile of dead bones covered with mold on the ground. Cassia stood there and waited.
After a while, there was an outlet of a waterway not far away. Seeing that there was no movement there, he was relieved that no one was paying attention and walked over.
There is a lot of concrete used to seal the seal, and there is also a layer of hard-sintered red bricks inside. Its overall thickness is about one meter. Even rats have not drilled a hole here for so many years. But the blasting made by Rocks
The projectile is specially designed to open holes in the base's protective wall, so there is no problem at all against this wall.
A large circular building block had completely fallen off the wall and was very heavy. Cassia pushed it inward hard to give him a gap to enter.
"Bang"
The hard and heavy rock-like building blocks fell inside, and the dust stirred up brought the air inside and rolled back toward Cassia's face. He quickly took a step back, and the afterglow of the strong light illuminated his face.
Zhang’s face became surprised.
What should exist in the abandoned lines that are forever sealed are the endless deep darkness and the air with the smell of decay. They will be like the tracks that no longer run through the train, and will be covered with rust in the continuous cycle of the four seasons, until
It was washed away by rain and mixed into the soil. But in the air coming from the pavement, there was nothing except the smell of dust that had not changed for thousands of years.
The darkness is gone, and the smell of decay is gone. On the contrary, there is even a little moisture.
A hundred meters ahead, Cassia's eyes caught a faint light. She also felt the vague air on her face.
Walking inside, the ground was dry, and the scenery under the light was an ordinary underground sewer scenery, nothing special. The end was not a piece of unexcavated soil. Cassia saw several thick red copper pipes there, which were larger than ordinary ones.
The pipes supplying steam are more than ten times larger, and the faint light comes from underneath several pipes.
"Shouldn't the steam pipelines and electric power pipelines supplying the city of Brino be buried at a shallower level?" Cassia's heart skipped a beat, and with some vague suspicion, he walked over quickly.
There were far more pipes than the few he saw in front of him. Behind these thick pipes, there were more densely packed pipes extending into the darkness. There were about dozens of them, and under the light of the flashlight, there were all kinds of pipes on them.
Different numbers.
Looking down, Cassia finally saw the source of the faint light that she had captured when she pushed away the building block not long ago.
Because he heard what Lina said in the morning, what he vaguely guessed at this moment was correct. The ground of Black Castle had been hollowed out long ago, which was very simple for the Imperial Mining Company. Then they built it into a smuggling center
