The vines released through the cracks at the bottom of the wooden door, a little sense, did not find an imminent Dongdong.

Qiao Haoyu was not in a hurry to go out, but roughly adjusted his state, and tried his best to extend the vines, after making sure that there was no one in the corridor, he even poured in along the cracks at the bottom of the doors of each room to investigate, and finally came to a conclusion that the entire floor was unattended.

The main building of the Changxing City Fire Detachment is a six-story building, and if there is still some credible news in Li Xueshun's statement, then it is basically correct that the high-rise building does not live in people. In order to verify his thoughts, Qiao Haoyu pushed open the window and leaned out to observe, it seemed that the windows were locked from the third floor, and they looked reinforced.

With these circumstances, Qiao Haoyu roughly concluded that the survivors here should be concentrated on the first to third floors.

Eat some dry food and water, and take into account that it will be dark before moving, after all, night is a relatively tiring time for humans, and the night will provide many convenient conditions for sneaking activities.

It was completely dark, and Qiao Haoyu continued his infiltration operation.

When Qiao Haoyu left the room, he found that there were some living corpses in the entire corridor and some rooms with large open doors, which looked more rotten and should have been dead for a long time. Some broken glass means that some birds should have been here, and those flying chicken aliens that I saw before may be one of them, and the mutilated corpses on the ground prove that Qiao Haoyu's idea should be reliable.

Downstairs is roughly the same, except that there are more traces of the battle, and it seems that people are gradually adapting to the catastrophe and pondering countermeasures.

The road was very smooth, when going down to the third floor, Qiao Haoyu found that the entire part above the third floor was isolated, the stairs down the third floor were scattered with various alien wreckage, and the messy filling completely sealed the stairwell, Qiao Haoyu roughly planed, and found that the staircase was finally completely sealed with cement.

Closing his eyes, Qiao Haoyu could roughly imagine the scene, the people who were evacuating down, on the one hand, blocked the stairs with all kinds of miscellaneous things, and on the other hand, stepped up resistance and closed this part of the passage with cement, then there would inevitably be martyrs and heroes after the break...... Shaking his head, Qiao Haoyu sighed softly, there are stories everywhere in this world, how many heroic hymns are there in this square inch? The staircase passage is closed by cement pouring, this situation may be a headache for others, but it is difficult for Qiao Haoyu, the reason is very simple, with the experience of opening holes in the wall, this small problem can be solved in minutes.

Despite this, Qiao Haoyu was not in a hurry to break through the passage, he needed to sum up what should be the most suitable way to go, for Qiao Haoyu at this moment, there were too many paths he could choose, so many that he needed to choose.

Option 1: The passage down from the third floor is completely sealed with cement, which can be broken.

Option 2: The safe passage into the corridor is reinforced with steel plates, and the scattered artificial traces in the passage guò can be judged that this door has been repeatedly reinforced and rebuilt, and the initial observation is a design that can be opened artificially. This part, if Qiao Haoyu is willing, can use the gold vine to destroy it with some effort.

Option 3: In fact, Qiao Haoyu can go without following the direction of the passage, you can find a wall at will, reinforced concrete may be an obstacle to the alien, but it is just a little bit of effort for Qiao Haoyu.

Option 4: Qiao Haoyu can break the wall again and go out directly to the first or second floor with the help of the vines.

People who are good at observing life will find some problems that people who are not good at observing life ignore, such as dividing by region, the architectural styles of a region are mostly somewhat similar and similar, especially the appearance seems to be almost the same, the internal structure is not too similar, and at most the decoration is different. For example, the style and layout of buildings in the same area, the same building period, and even the same type of buildings are not too similar. Although this law is only an approximation, it is obvious that Qiao Haoyu is a person who is good at observing life.

In the similar buildings in Changxing City that Qiao Haoyu recently entered, buildings with similar appearances usually have halls on the first floor, and the left and right sides of the hall are basically corridors and door-to-door rooms.

Moving on to the third floor, there are many changes, some of which run through the central staircase, and some of which run through the side staircase from the second floor......

The question Qiao Haoyu is thinking about is which layer those heads and brains are most likely to stay in.

Should stay on the second floor......

In Qiao Haoyu's concept, the leader should be in the middle, will not be attacked by the enemy, can issue orders with peace of mind to ponder countermeasures, and the most important thing is not to die first!

After basically thinking about the key points of his investigation, Qiao Haoyu chose to break the line of the staircase passage, because if the metal door leading to the corridor was destroyed, if there were patrols in the corridor, a fierce battle would be unavoidable. Although Qiao Haoyu was eager to kill a few people, it was for the people on Li Xueshun's side, just look at the traces of the completion of the sealing of the passages, Qiao Haoyu is still full of respect for the people of this army, it is impossible to complete the closure of the passages without sacrifice, there are heroes and martyrs here, even if they have died.

The technique is similar, after roughly clearing out a small area, Qiao Haoyu made the reinforced silk rattan penetrate the cement watered fortification.

The thickness of this part of the poured cement was completely unexpected by Qiao Haoyu, Qiao Haoyu estimated that the entire staircase was poured to death, although this increased Qiao Haoyu's consumption, but in another aspect, it was actually good news, which means that the strength of defense and patrol may not be particularly strong below.

Sure enough, after Qiao Haoyu opened a passage like a mouse, there was no one guarding here.

The door leading to the corridor here was not reinforced, but it was concealed, Qiao Haoyu released the vines from afar and gently opened the door to the gap, and then the growing vines entered the corridor aisle along the gap, and after the preliminary judgment that there was no one, he increased the pull of the vines, and opened the door to allow him to enter calmly, and finally cut off the connection after hardening the vines, and tied it to the stairs like a rope to fix the opening and closing of the door.

Sneaking into the corridor quietly, suddenly the wooden door made a tooth-aching squeak when it opened, causing Qiao Haoyu to quickly pounce on the T-junction of the safe passage, holding his breath and prostrate on the ground. Immediately, two men dressed as soldiers came out, fully armed and carrying flashlights, which meant that they were on duty at night, and from the slightly loose appearance of the air and the sky, it was likely that the last few days had been relatively peaceful, and people's nerves were loose.

The hunter generally waited patiently, and when the two soldiers passed by the safe passage, Qiao Haoyu jumped up like lightning, "Boom", two hand knives cut the back of the necks of the two soldiers, and before the two soldiers fell, Qiao Haoyu had already gently hugged them.

In the consciousness of these two soldiers, they had just changed the guard and were in a trance, when suddenly a black shadow flashed, and then they lost consciousness in front of them.

The two soldiers woke up again, they didn't know where they were, they were all black, they felt that they were bound up and down, and they couldn't move at all, suddenly, a dazzling light shot towards the front door, and the person holding their flashlight should be a person, but because of the light, they couldn't see each other's appearance clearly, and they wanted to make a sound, and found that their mouths had been blocked by something.

Maybe it was due to interest, or maybe it was a whim, Qiao Haoyu decided to have a bad taste.

The two soldiers have now been tied with vines, and there is nothing mysterious about the place, it is the cement potting place on the third floor, there should be few people here to patrol, and Qiao Haoyu just dug a hole, and the front and back are locked with vines, which is definitely a relatively private space, and Qiao Haoyu deliberately reorganized several layers inside and out in order to insulate the sound. He considered that he might be a soldier, so he deliberately made such a place, and was ready to use the more mischievous methods in his mind to extract a confession.

The words are divided into two ends, and the story in the eyes of these two soldiers is this.

I woke up again in a daze and found that I couldn't move all over my body, and I couldn't make a sound. The place they were in was very dark, almost completely devoid of light, which made it impossible for them to tell where they were, and they felt that the space around them was unusually small, and they really couldn't figure out that this was a magical place.
