Cosma Empire

It may be because of their rich experience, or because of their keen senses, Dover, Savi, and Katerina all think that this delivery boy is definitely not a killer.

He lacked a spirit, something special, maybe crazy, maybe calm, but he just didn't have it.

Dogs won't eat mud that looks like shit, but they won't let go of shit that looks like mud. They always have a way to tell the difference.

"Who asked you to deliver food?" Although Katerina knew that this young man was probably just a food delivery person, the work that should be done still had to be done.

She squatted in front of the young man, and pressed the muzzle of a gun against his temple, "Think clearly before answering!"

The boy's body was trembling slightly, he squeezed his eyes as if he was thinking, opened them three to five seconds later, and gave the phone number of the restaurant he worked for and the boss who asked him to deliver food.

Two agents who carefully opened the takeaway box outside shook their heads at Katerina. The box was indeed food, not explosives. After some simple test strip investigations, there was no poisonous ingredient in the food.

On the one hand, they called the investigation team to control the people in the restaurant and track down the person who placed the order. On the other hand, they did not let the young man go, but locked him in the kitchen.

Although I don't understand why the killer would send a food delivery man over to alert them, all of this must have a clear purpose, and it is very likely that the killer who came to assassinate Du Lin is a veteran.

Let all the agents stay at their posts again, Katerina went back to the door of the utility room, knocked on the iron door, and said with a dull voice, "Are you still inside?"

"No, I'm not here!" Some out-of-tune voices are full of strong confidence and optimism. The dark enclosed space does not seem to be able to make Du Lin feel any atmosphere of fear and depression. He is even interested in joking at this time !

Katerina met a lot of superficially powerful people in MI, from trained spies from other countries to celebrities and politicians.

These people don't need to use too many means, just locking them in a closed space is enough to make them feel deep fear, and even after a long time, some people will go crazy and go crazy.

This was not seen in Du Lin. The joking voice and emphasis made her a little disgusted, because she realized that this was an abnormal person.

But it's not surprising if you think about it carefully. After all, Du Lin has many titles and titles. If he is a little bit normal, it is impossible to get to where he is today. This is not a derogatory explanation.

There was a moment of silence inside and outside the door, Katerina turned and left, and began to inspect the villa.

It didn't take long for the outside agents to call back. They found the restaurant and arrested all the staff, including the guests who were dining, to verify their identities.

There is nothing very special among these people, and after a friendly exchange, nothing special is found.

Now these people have been transferred to the local police station for detention, and special agents will go together to continue to interrogate these people.

In the restaurant, they found a note discarded in the trash can, which stated the time of ordering,

The content of the meal order, and the villa where Du Lin is currently living.

According to the front desk of the restaurant, the person who called to order food was a man with a mellow voice. He sounded about thirty to forty years old. His speech was not fast, but his articulation was very clear.

After hanging up the phone, Katerina kept thinking about a problem. If the food delivery person was simply attracting their attention, then there was no need for it at all.

With a little more means in the assassination process, there will be more possible loopholes. As a senior agent of the Military Intelligence Department, Katerina has been working in the empire's internal anti-espionage and anti-terrorism investigations.

She is very clear that any extra action may become the key to solving the case, just like the information they got from the girl who answered the phone, they can already lock the criminal's voice and approximate age.

This is not a good thing for the killer who tried his best to hide himself, and he exposed some personal information.

But if it is said that this person is useless... Katerina felt that something was wrong. This young man who delivered food must have played a role in this assassination, but she still couldn't figure out what use he was.

Let it go, that's impossible, he hasn't completely cleared himself of his suspicions, the only thing he can do now is to temporarily lock him up in the villa, and make plans after dawn tomorrow.

"Cheer up, pay attention to your position, and call for support immediately if there is any situation!" Katerina repeatedly asked several times, and began to patrol around the villa without missing any place.

Time passed like this bit by bit, as if the killer's assassination was just a wrong judgment of their guesswork, or the killer had chosen to leave after seeing the strict security measures here.

Katerina was a little anxious, the calmer she was, the more urgent she felt, as if a killer could appear in this villa anytime, anywhere.

At two o'clock in the evening, there was an almost inaudible sound from the closed window in the kitchen. In the gap less than one millimeter between the window and the window sill, a wire quietly passed through. The wire was at a ninety-degree angle. , after most of it penetrated in, the horizontal right-angled iron wire slowly rotated.

Part of it slowly went up, and it had already touched the latch of the window.

The movement of the shadow that was blurred to the point of being almost invisible outside the house was quite slight and patient.

Just a little bit, bit by bit, the latch was pushed open silently, and then a gust of wind blew the curtains, and something squeezed in from outside the window less than 35 centimeters long and wide.

The curtains were deformed, and a pair of feet had landed on the cabinet.

In the next second, a clean head appeared behind the curtain, and he jumped down as deftly as a cat, without making a sound.

The takeaway guy who was locked in the kitchen was lying on the bar and sound asleep. He walked over lightly, and stood behind the guy like a ghost, with his left hand through the gap between his arms and neck , and then slammed back!

At the same time, he pressed his head with his right hand and twisted it lightly. The takeaway guy didn't make a sound, and the strength of resistance disappeared completely.

He quickly took off the takeaway boy's clothes, stuffed him into the cabinet under the cabinet for storing utensils, then changed into the boy's clothes, put on a yellow hard hat, and lay down where the boy was sleeping just now.

At this moment, he counted silently in his heart.

ten……

Nine……

eight……

...

three……

two……

one……!

With a loud bang, the boiler in the basement of the villa suddenly exploded violently. If there are professionals on the scene, they will be able to tell others at the first time that this must be caused by the high internal pressure of the boiler.

That's right, the wrench came in handy!

After two days of careful observation and planning, he even bought an identical boiler to try. He has figured out how long it would take for the boiler to explode if the pressure cannot be released. Completely shut down.

The explosion alarmed all the agents in the entire villa, including Du Lin.

When Katerina and Dover rushed into the basement, an agent on duty had already fallen in a pool of blood.

The exploding boiler was like a gigantic bomb, and no one near it had any chance of surviving.

Duffer stepped forward, ignoring the steam and boiling water, and checked the vents and water inlets. There was no damage, and Katerina watched from behind him.

The two ran upstairs almost at the same time. If it wasn't an accident, then it must have been an accident to attract their attention!

It's just that they didn't notice that next to the boiler room is the constant temperature system of the villa, and the constant temperature system and the boiler are actually connected together.

It may not be used in summer, but in winter the constant temperature system will send steam and hot water to the entire building through the water circulation system buried in the walls and floors, so that the temperature in the entire villa can be kept at a suitable temperature.

In summer, these are not needed to heat the villa as a whole, so a water inlet valve in the circulation system is closed.

At this time, the boiler has completely burst, and the water outlet of the water circulation system is connected to the water outlet of the boiler. The water distributed in the various pipes of the villa in the entire water circulation system is rapidly losing.

After losing the ice water, the temperature in the villa began to rise significantly. It was night at this time, and the people in the house could not see or notice that there were some special places on the walls and eaves outside the villa. Small things of different sizes and shapes.

One of the places where these things exist is located in the vents of the ventilation system.

Because Dulin's villa is much larger than ordinary villas, some rooms in the house cannot be directly connected to the outside world, so the ventilation system needs to be ventilated regularly.

At this time, the temperature in the house rises, and the wind blowing out during the exchange is no longer cool. Suddenly, a fist-sized thing hanging under the vent emits some white smoke, and then the smoke becomes thicker and thicker. The smoke was drawn into the vents during ventilation!

Katerina, who was guarding the first floor of the villa, searched for several times but found nothing, but at this moment, she and the others suddenly coughed a few times, and then they were horrified to find that the cracks in the doors of some rooms began to leak out. It spits out some white smoke.

Katerina's face darkened. They came to protect Durin from assassins, not to fight against biological and chemical weapons. Who would wear a gas mask at this time?

Thinking that the killer would most likely enter the empty villa after they left, Katerina was caught in a balance.

It is to leave with Du Lin to avoid a one-on-one situation between him and the assassin.

Let Du Lin stay in the safe house and wait for rescue.
