To ensure safety, Xu Jianguo also equipped himself with a portable gas cylinder, because he was worried that the air in the pipeline would not circulate for a long time and it would be dangerous if he suddenly came out of the space portal.
However, when he actually appeared in the pipe, he found that his worries were unnecessary.
Not only is there no damp or moldy smell in the pipe, but it is unusually dry. If you feel it carefully, you can even feel a slight air flow passing through.
Xu Jianguo speculated that there should be ventilation devices at certain connection points of this pipeline.
Because more than half of the space in the pipeline is laid with cables, the space for Xu Jianguo and his companions to move around is actually very limited.
All four of them remained in a prone position, feeling extremely uncomfortable.
According to Xu Jianguo's order, Xu Shiyi, who was carrying tools, was in the front, followed by Xu Shisi, Xu Jianguo was in third place, and the last was Fu Bo.
The reason why he placed Xu Shiyi at the front was because the skills he was learning at the time were related to mechanical manufacturing, which was also why Xu Jianguo placed him in the technology factory.
Because communication cables of the South Korean defense department were laid in here, Xu Jianguo was worried that there might be sensors or alarm devices installed in the pipeline, so he asked Xu Shiyi to be at the front so that he could respond in time if anything was discovered.
Whether it is to block the signal or directly dismantle it, Xu Shiyi, who carries the tools, is the best choice.
After Xu Jianguo gave orders to several people using the system panel, the four of them began to crawl forward along the pipe.
This method of communicating through the system panel was due to a suggestion made by Fu Bo to Xu Jianguo. In some special environments, no sound can be made. This is why special forces mostly use sign language during operations.
Because Xu Jianguo has the Eyes of Time and Space, the dark environment in the pipe has no effect on him. As for the other three people, they are space servants, and night vision is their basic ability, so there is no need to worry.
The four of them moved very quickly and in a short while they had advanced almost a hundred meters. Xu Jianguo could feel that this pipe was not straight and horizontal, but had a certain downward angle, which meant that they were now moving deeper.
At this moment, Xu Shiyi, who was at the front, suddenly stopped. Then, Xu Jianguo received the message from him in his mind.
After seeing the news, Xu Jianguo secretly rejoiced in his heart, thinking that his caution was correct. Xu Shiyi really found a sensor on the pipe wall in front, and according to his speculation, it was also a sound sensor.
This shows that there are still experts in South Korea's defense department, but these experts should be wary of North Korea. They would never have thought that the one who discovered this sensor today would be an alloy robot with super high IQ.
Under Xu Jianguo's command, Xu Shiyi successfully blocked the signal transmission module of the sensor in less than 30 seconds without causing any damage to the appearance. Even if someone came to investigate afterwards, they would not find any clues. At most, they would see traces of crawling on the pipe wall.
After solving the problem of the sensors, the four continued to move forward. Along the way, Xu Shiyi solved a total of six sensors.
In addition to sound sensors, there are also vibration sensors, but these things that seem very advanced in this era are worthless in Xu Shiyi's hands.
Soon, the four of them arrived at the end of the pipe, which was a wall made of poured concrete. All the neatly arranged cables were sent to the other side of the wall through a metal pipe with a diameter of only 40 centimeters.
Perhaps for the convenience of construction, the space at the end of the pipe is much larger than before, at least enough for four people to accommodate at the same time.
Xu Jianguo came to the concrete wall and looked through the Eye of Time and Space. He found that behind this wall that was nearly one meter thick was a closed room of nearly 100 square meters, similar to the underground power room of the Big Parrot Museum. There were no windows in the room, only a sealed metal door. There was no switch handle or lock on the door. It seemed that it was a door that could only be opened from the outside. Outside the door was a long corridor.
After entering the room, the cables were connected to several devices whose functions were unknown. There were many indicator lights flashing on these devices.
After observing the situation behind the concrete wall, Xu Jianguo looked up again and found that they were not directly below the Fushan Port office building, but below an open space not far from the north side of the building, at a depth of nearly ten meters.
Now that he had found the location, Xu Jianguo did not delay any longer and immediately asked the three of them to start working. After all, he had promised his wife to go early and come back early.
Because Xu Jianguo and the other four are still in the pipe, and there is a concrete wall in front of them.
According to his previous observation, the entire enclosed room was made of nearly one-meter-thick concrete.
Therefore, if weapons were to be installed, they could only be installed at the bottom of the closed room. So after thinking for a moment, Xu Jianguo began to use his ability to collect items in space and collected some of the soil under the secret room into the space.
Of course, it is necessary to avoid some reinforced concrete pillars used to reinforce the foundation.
