The system is the king of the counterattack master

Without a map and without a low-light mirror, Han Xiaodong fell into an extremely embarrassing situation.

Sitting helplessly on the steps, his mind went blank, and he didn't know where to start his next step.

"If it were you, where would you build the basement?" Seeing that he was frowning, K began to help him find ideas.

"I can't figure it out." Han Xiaodong shook his head: "I'm not from that era. How would I know where they were going to build the basement? But you, aren't you omnipotent? Help me analyze it. The basement was built in Where is more suitable?"

"I'm not a human, how do I know?!" Seeing Han Xiaodong kick the ball back, K immediately counterattacked. It's not a fortune teller, so how could it know everything.

Sighing, Han Xiaodong leaned his head against the wall and cast his eyes on the ceiling above his head.

There is a hole in the ceiling, I don't know how it was caused, through that hole, you can just see the ceiling of the corridor on the second floor.

Seeing the roof of the other floor through the big hole, Han Xiaodong suddenly fell into deep thought. After pondering for a while, he suddenly asked: "Tell me, according to the information you have, what are the conditions for the location of the air-raid shelter?"

This is not a difficult question to answer, and K immediately replied: "First of all, it must be concealed, and second, it must be suitable for the evacuation of the crowd. The surrounding soil must be strong enough, and the terrain must not be easily attacked. During construction, multiple ventilation openings must be built. ..."

"That's it!" Han Xiaodong seemed to have grasped the point at once, stood up suddenly, and rushed to the roof of the laboratory.

Standing on the roof of the building, he looked around. Because it was near the nuclear facility, there were not many buildings around. Standing on the roof of the laboratory, he could even see a few kilometers away.

At this time, the sun was about to set, and the dim sky made the vision not very good.

Han Xiaodong was searching for the target in his heart at an extremely fast speed. Suddenly, his eyes focused on a small soil slope covered by messy bushes in the distance, and a smile appeared on the corner of his mouth.

"What exactly are you looking for?" K was baffled by his sudden action, and didn't know what hint his words had brought him.

"Our mistake was that we limited our attention to the building, but if the basement is to be built with dual functions of air-raid shelter and radiation, then it must not be built in the building.

Because in the event of an attack or explosion, the air-raid shelter built in the building is equivalent to a big coffin, and everyone can only be buried here. "

Han Xiaodong rushed downstairs quickly, moving towards the target he saw, while explaining to K.

"There is another requirement for anti-nuclear radiation, that is, the wind direction and the possible explosion direction must be taken into consideration. In combination with these points, the entrance of the basement must be on the back of a raised terrain. Only in this way can the hidden Minimize damage as much as possible.

The last, and most critical, is concealment. During the Cold War, nuclear facilities had to be protected from enemy attacks, and air-raid shelters had to be protected even more. Therefore, it must be built in a particularly concealed place. I was looking for a place that met this requirement just now. "

"Is this what you came up with looking at the hole in the ceiling? Isn't it too illogical?" K was always struggling with logic.

After all, he is a system, not so emotional, all associations are based on clues and conditions, this ability to come up with so much content through a hole in the ceiling always makes him unable to understand.

"That's right." Han Xiaodong kept walking, and after listening to K's tangled words, he just shrugged his shoulders noncommittally: "That hole reminds me of the Japanese laboratory in the school. If we only look at the appearance, we will never see it." It is impossible to find where the entrance to the basement is, and only by abandoning the entanglement of phenomena and pursuing the essence of things can we find the truth."

While speaking, Han Xiaodong had already arrived near the hill, and without thinking about it, he dodged into the bushes.

The bushes were very dense, and Han Xiaodong pushed aside the bushes in front of him, and walked deep inside step by step.

The shrubs covering the soil slope look ordinary from the outside, not much higher than the surrounding flat ground, but once inside the shrubs, it will be another world.

The slope extends downward at fifteen degrees, and then goes up after 200 meters. Its end is connected with a forest, so it can’t be seen from the outside that this is a low-lying area. It is not so much a bush as a huge one. Even if you look down from the air, you can't see anything special at all.

This is the best bunker, a natural bunker, whether it is air defense or defense against nuclear radiation, it is the best natural barrier.

After searching for a while, Han Xiaodong finally stopped in front of a weed.Gently pushing aside the weeds, a square hole with railings appeared in front of his eyes.

"It's a vent!" K saw the purpose of the hole at a glance.

The corners of Han Xiaodong's mouth raised slightly. This was exactly what he was looking for. If it was really a gate, it would be a troublesome matter.

Now what he has to do is sneak into the battle. If the door is pushed open, even a fool will not respond, but the vent is different, as long as he avoids the detection device inside, he can sneak into it silently.

The iron fence is very strong, and there are sensors, which are connected to the alarm system. As long as someone forcibly removes the fence, the inside of the base will know immediately.

It's a pity that this little trick can't stump Han Xiaodong. Although the detection equipment can't be used, other tools are fine.

After taking out the toolbox, it took less than half a minute for the sensor to be removed. As for the removal of the fence, it was a laborious task. He used a hydraulic crowbar to completely dismantle the fence.

Throwing the fence aside, Han Xiaodong probed into the vent. At this time, the sky had begun to turn dark, and the bushes had already blocked the sun, so he could only use a wolf smoke flashlight to observe inside the vent.

However, the wolf smoke flashlight, which can reach a distance of [-] meters, still does not shine on the bottom of the vent. This vent is like a bottomless pit, swallowing all the light that enters it.

"Damn, how deep is the cultivation." Han Xiaodong couldn't help complaining.

You know, this ventilation channel only leads to the original basement, and it is not known whether it is connected to the creator's base. Now only such a channel is so deep that the creator's base may be three feet underground. 500 meters below.

This is a daunting project.

The airway used to have a metal ladder, which has now been removed, apparently to prevent people from entering the basement along it.

This also did not bother Han Xiaodong, so he put on his climbing tools and began to climb down along the air vent less than two square meters away.

The road was unimpeded, and it was even easier than rock climbing games in shopping malls. When climbing to a depth of more than 60 meters, K issued a warning:

"Don't move, I've detected electromagnetic waves, there's a radar alarm down here!"
