Steel steam and flame

There was not much rest time. After Cassia went to a separate room to put away her luggage, No. 5 came to the spacious living room on the second floor and stood next to the communicator in the corner, holding something like a manuscript prepared in advance. When everyone arrived, he began to explain the various facilities and machines one by one, as well as the times for using them, and the passwords.

The construction of the entire warehouse can be traced back more than ten years ago. All the materials used were purchased from the three giant countries, and they are still high-end goods. Bulletproof materials are used throughout. There are many machines and weapons arranged throughout the interior of the small building. Common firearms such as heavy machine guns, artillery launchers, and four small-caliber fixed-shell cannons are arranged according to the four positive directions. All controlled by an analytical machine in the basement. Each fixed weapon can be adjusted in position through control, but it has its own password. This is roughly what the man introduced, as well as the specific control methods later.

Not only that, there are high-explosive mines activated by signal lines around the small building. After the laboratory base was opened, it was manually updated, which can be very useful in some emergencies.

The next morning, No. 5 taught Cassia and the others how to use programs and manually control various machines before returning to the hall. Expanding the panoramic map of the town, he introduced one by one which locations in the town were safe house-like rooms, and which residences were occupied by unsuspecting soldiers disguised. When necessary, he could contact them with secret codes to help him.

What's particularly important is that there are three red dotted lines connecting this small building, and one leads to the nearby mountain range, which is directly connected to the laboratory base. Usually when the laboratory has needs, it will contact them through the communicator, and then transport the materials from this line to the designated location. There is a large cavity at the end, and an elevator is built beside it. The control of the elevator is one-way, and there are several safety doors in the middle that are locked. It will take some time to destroy it with pneumatic weapons.

One line extends towards the outskirts of the town, heading towards the nearest city. The safe escape passage is the most appropriate name. In an emergency, you can abandon this place and take this route to quickly leave the town. There is an underground parking lot at the exit, right next to a road. Recently, Cassia and the others had to spend time driving their respective limo cars there and putting them away so that they could be used at any time.

The remaining one has no exit, but spirals around most of the town's underground area. However, it can be seen from some points marked on this dotted line that there are probably many nearby mobile entrances and exits on this route. When encountering an enemy attack, it is used to quickly get behind the enemy. It is also an emergency passage to call for support and transfer to the interior of the small building. It is located throughout the town and is a very convenient route. However, No. 5 made a very serious statement that during normal times, this route must be closed.

"These three dotted lines are all tunnels, with an average depth of about fifty meters. Just think of them as man-made mines. The tunnels have mobile tools like mine carts and are reinforced with alloy steel plates nearly ten centimeters thick. They have amazing defense capabilities and high speeds. It's very impressive." After No. 5 introduced the basic situation of the town, he explained the daily patrol range, exploration locations, where to get food, etc., "You all know the functions of the three tunnels. Here is a reminder. , this small building, including the warehouse in the basement, and the tunnels, are all equipped with explosives, which were all updated when the base was activated. The amount is enough to blow up the place more than two or three times at the moment of detonation."

"Self-destruct device?"

No. 5 nodded: "The last resort is almost impossible when encountering a situation where it can be used. We do not rule out the possibility, but it is impossible for us to know the password of the self-destruction device. In the hands of other people, if you have the opportunity to enter the laboratory in the future You can see him in the base.”

"That's all I should say. In the afternoon, based on your information, I will tell you the specific work of each one one by one. It is best not to interfere with each other and just do your own thing. Let's start, this mission is indeed like a vacation. But in terms of vigilance, everyone should not lower their vigilance. Because once there is an attack here, you know in your heart that it will definitely not be a team of just a few people."

Number 5 left from the second tunnel in the evening, leaving Cassia and others with not only information but also several maps, including the layout of the small building. The other three people didn't mean to greet each other and get to know each other, so Cassia went straight back to her room to pack her luggage.

In addition to weapons and ammunition, Cassia also carried many books. According to the arranged schedule, every two people take turns to monitor the surroundings at night for one week. It's not him now. After Cassia checked the room, he went to the window and used the maximum radius of sound wave pulse to encompass the entire town and detect it carefully.

Six kilometers away, except for patches of irregular farmland, Cassia saw no shadow of the nearby mountains. The distance is farther, but there is no need to worry. Sooner or later, the sound wave pulse will be able to lock the location of the laboratory base. Cassia was very interested in what research was going on inside. In addition to the four forces, the empire itself has more than half a million dragons in captivity. The extraction of surgical materials only accounts for a small part of the materials on dragons. More answers may be found during this time as to the uses of blood, scales, bones, etc.

At eight o'clock the next morning, Cassia went to the living room on time to change shifts with No. 1 and 2. Holding the revolver and following the range and route mentioned in the information, Cassia returned to his residence in two hours. Going straight from the inside of the small building to the basement, the sound wave pulses quickly described a storage warehouse wrapped in various protections such as concrete and steel alloys.

There are about hundreds of alloy jars neatly placed on the shelves, and there are about twenty rough ultimate alloy embryos. The number is indeed huge, so much so that Cassia is very excited at this moment. But it does not belong to him. There is a way to destroy this layer of defense in a short period of time and get inside, using the devouring method to absorb all the dragon blood. However, there is no way to pursue him afterwards.

Others don't know, Cassia knows very well that in the distance a few cities away, Adolf and Trevikan may also be paying attention to this place. With no other ideas, Cassia explored all the structures in the basement, and after thinking about it, he walked towards the tunnel leading to the mountains.

The basic exploration is estimated to be 13 kilometers away, and the round trip time is about ten minutes. Cassia thought, the perception unfolded instantly, and the sound waves reflected extremely quickly in the narrow passage, forming a tunnel drawn by lines, spreading into the distance. . Two or three seconds later, Cassia's voice was completely swallowed by the tunnel.
