Zheng Xiao squatted on the passage, inspecting the surrounding walls and the ground under his feet inch by inch, not even missing every gap and every depression.
After thinking over and over again, Zheng Xiao felt that there must be something fishy about this passage, otherwise there would not be the traces he found, so he began to check this passage.
Checking the passage bit by bit, Zheng Xiao walked from the iron door on one side to the other side. The details were amazing, and it was three points more detailed than a woman's embroidery.
In this way, Zheng Xiao inspected all the way forward, and soon Zheng Xiao had inspected about one-third of the length, but found nothing.
"Impossible, there must be an agency somewhere." Zheng Xiao was not discouraged. He firmly believed that his judgment was correct.
After continuing to explore forward for two or three steps, Zheng Xiao's eyes suddenly froze because there seemed to be something abnormal about the wall on one side of the passage, which was a little more sunken than the surrounding walls.
Stopping before taking out the wall, Zheng Xiao stretched out his hand and touched the depression on the wall, feeling it through his palm.
For a full thirty or forty seconds, Zheng Xiao kept this action. Finally, he made a move and pressed hard with his palm.
Then a click was heard, and the wall sank, covering an area the size of a palm.
As the wall sunk in, the wall on the other side also changed. The wall moved silently to one side, revealing a passage behind it.
The entrance to this passage is about the same height as the passage Zheng Xiao is currently in, but under the illumination of the flashlight, it goes all the way downward, and it is unknown where it leads.
Zheng Xiao rushed to the entrance of the cave and looked inside with a flashlight. He found that the inside was very long and the flashlight could not illuminate the end.
After thinking about it, Zheng Xiao still got into this passage. He didn't find anything else anyway. This road was a new discovery after all.
The passages are all made of blue bricks, and the ground is very clean. There is no dust or other things visible. It is estimated that someone cleans it frequently.
Stretching all the way underground, Zheng Xiao kept moving forward along this passage. According to his calculations, it should have been a continuous downward journey. It was estimated that it should have been forty or fifty meters deep underground, and then the trend became gentle.
At this time, Zheng Xiao had already walked a distance of three to four hundred meters.
When the passage turned from downward to parallel, Zheng Xiao discovered that an iron gate appeared halfway through the passage. This iron gate firmly blocked the passage. If he wanted to pass, he had to pass through this iron gate.
He rushed to the iron door in a few steps and Zheng Xiao began to study the door lock. He had a feeling that after this mission was over, he would open a locksmith company and the business would be very good.
The lock of this iron door was much more difficult than the previous one, but it was still easy for Zheng Xiao. It took him more than ten seconds to open the iron door.
Pushing open the iron door, Zheng Xiao found that behind the iron door was a wider passage, which was more than twice as wide as the current passage he was in.
The floor was covered with thick felt blankets, and the walls on both sides were covered with soundproof felts. The ceiling was exposed on the top, with bright electric lights hanging on it.
Zheng Xiao got through the iron door and then closed it with his hand. This time he put on some disguise to avoid being discovered.
His feet stepped on the thick and firm felt blanket without making a sound, and Zheng Xiao tiptoed towards the end of the passage.
There is another iron door, probably leading to somewhere else.
When he came to the second iron gate, Zheng Xiao's expression became obviously more serious. It seemed that he had noticed something fishy.
With such strict protection, even a rat barn can pass. After all, a rat barn is not qualified to be protected by layers of iron doors.
Moreover, this iron door is different from the previous two iron doors, both in thickness and material. It is obviously something that has been carefully selected.
Zheng Xiao took out his tools and began to study the door lock. He squatted in front of the door lock, fiddled with the tool in the keyhole, and listened to what was going on inside.
The door lock was opened little by little, and most of the circlips inside had been popped open, leaving only the last few mechanisms that had not yet been unlocked.
More than ten seconds passed, and Zheng Xiao finally heard the familiar clicking sound coming from the keyhole, followed by the door lock being ejected.
Zheng Xiao did not rush to open the door, but put his ear to the iron door and listened to the sounds on the other side.
This door was obviously different. Zheng Xiao was worried that if there were Japanese people on the other side, if he pushed the door rashly, he might alert others, so he had to make sure that there was no problem on the other side before he could open the door.
It was quiet across the iron gate, and no sound of human activity could be heard. It seemed safe, so Zheng Xiao decided to open the door.
Reaching out and holding the door handle on the door, Zheng Xiao first turned it slightly, and then found that the door was indeed not locked, and the door shaft seemed to have been dotted with engine oil, so it opened
There was no sound at all.
With a strong effort of his arm, Zheng Xiao pushed the iron door open. The flashlight in his hand was extinguished, so that no one on the other side would be discovered, and he could find his target more freely.
There are air-dead wind lanterns hanging high in the passage, which are rarely seen in other places.
Qi-dead lantern. Abbreviated as "Qi-feng lantern", it is the round red lantern hanging on the Tiananmen Gate Tower today. It is a typical festival decoration. Some people call it "begging for sealing lanterns" for the sake of good luck.
In those days, most Qi Si Feng lanterns were made of red tung oil paper, translucent, decorated with green ruffles on the top and bottom, and the belly of the lantern was decorated with the words "Hongxi" in bright red or gold. In the old days, it was hung on the door of the mansion during festivals.
On both sides of the street gate, there are letters of surname and "tang name", such as "Yishantang Wang", "Jishantang Kui", etc.
In fact, the Qi Si Feng Lantern is a kind of lantern that was lit in ancient times. It is not easy to be blown out by the wind, so it is called Qi Si Feng Lantern. It uses white paper, which is very thick. In the past, it was used to paper the windows with a candle in the middle. It looks like
Lanterns are the kind of lamps that cannot be extinguished by the wind. They existed in the Eastern Han Dynasty. During the Three Kingdoms period, there were wind-killing lanterns in front of everyone's door. Later, they were made of paper tightly, like paper bags, and the principle of heat rising was invented by Zhuge Liang.
"Kongming Lantern".
This is a kind of lighting specially designed for use in the wild and outdoors. Its biggest feature is that it can be windproof and dustproof, economical and easy to use.
The original qi-dead wind lanterns were all made of white paper, but the qi-dead wind lanterns Zheng Xiao saw were not made of white paper, but made of glass, which was more convenient to use and economical.
Zheng Xiao flashed into the passage, first turned around and pressed against the wall, and then began to observe the surroundings. He found that he was still in a passage. If there was any difference from the previous passage, it was that it looked wider.
There was no one in this passage, and there were still blankets covering the surroundings and in front of him. While soundproofing, it also made the lights in the passage seem even more lonely and dim.
