Speaking of the two people running back to the location of the Guli well, the old king to see the appearance of the Guli well above the ground of 30 centimeters is also a little puzzled, but around the Guli well mouth turned around, which stopped the fat man's action.

"Wait, this is definitely not like that open, look at this design should be built by the Germans, and then you look at the rotating axis of the lid cast iron, here is a word gully!"

Zhou Hai followed the direction of the old king's fingers, where there seemed to be some raised shape, but really could not see what the word was, and Zhou Hai was puzzled.

“How can you see the rust?”

Old Wang's face with a gentle smile, stretched out his fingers and gently touched the position of the word casting, Zhou Hai understood his meaning, this is to let him try it for himself.

Zhou Hai reached out and touched it, and he could touch the bulge, and his eyes saw it clearly.

At this time, Huang Zhongsheng did not come, the following situation is not clear, Zhou Hai did not dare to let Zhang Qi they look for a metal brush brush, afraid of touching something.

But the king did not stop, and then said:

"We are in more contact with the troops, because we were responsible for these tasks, and the Germans built such a Guli well, which was not used for drainage systems.

For drainage are flat, generally on the side of the road, below is the sewer pipe, and this is built in a secret place, higher than the ground of thirty centimeters, generally used for escape, or a certain fortification of the passage.

As for this, there is generally no space to hang bombs, and I see that the chain is nothing more than a zipper of a spring lock.”

Saying that he reached out and gropeted around the wellhead for a moment, he found a slightly loose stone, took gloves, spit out the gum of the mouth and pasted it on the stone, and pressed the glove to the gum, and pulled it out with force, and turned out.

Zhang Qi quickly flashed his hand, this position is very wide, the entire flashlight can be sent in, the moment the manhole cover under the light, the fat man looked up and smiled.

"Master Wang really has yours, the key moment to solve the problem for us, I see that there should be no problem, there seems to be a step, but the steps are very steep."

The old king turned the brick over, there was a j-shaped depression on the side, gently kowtow on the ground, fell out of a thing, shook off the open surface of the oil paper, two exquisite hooks fell out, the hooks or brand new face with rust-proof grease.

The fat man threw the hook to the madman.

"Little beam pulled the chain, heard the click and remained motionless, and I and the madman opened the manhole cover."

Xiao Liang certainly had no problem, quickly tugging on the chain, it seemed to be laborious, and made a clatter.

Old Wang smiled, he had just seen the truth from a distance, it is estimated that the initial tugging at the chain is because the fat man is lying on the face so he can't pull, the fat man glanced at him and what he did not understand, blinking at him, and quickly picked up the iron hook.

The madman and the fat man pushed hard, the whole manhole cover was slowly lifted, and the smell of wet cold and mildew was instantly rich, but the face was close to the wellhead, and the wind was blowing under it clearly.

"Open up for a while, and wait for the yellow detachment to bring us to equip us again."

Everyone looked at the wellhead, and the old king picked up the lightning of the ground, lying on the wellhead, and shone down, and Hunan also came with interest at this time, standing on the edge of the wellhead of the stone looking down.

This hope was found, and the wellhead seemed to have a well cover.

However, it seems that the time is long, too humid environment makes it rot, at this time has been broken into brown-red iron filings scattered at the bottom of the well, only a circle of the wellhead has some traces.

No wonder just can not see anything, the original wellhead below the horn shape, along the wellhead of the metal simple ladder down a meter or so, there is a small platform.

The platform is not large, more and more out of the expansion to form a horn shape of the rotating stairs to extend downwards, reaching down to shine, it seems to have a channel in several directions, but the brightness is limited to see all.

“That seems.It's an escape!"

Old Wang gave a judgment based on his own experience, Zhou Hai nodded, the idea is somewhat similar to his own.

“I guess there’s a basement under this house.

I just didn’t think it was a passageway, but these vines and porches became the best cover-up, and who could have imagined that there was such a secret here?”

Zhou Hai squinted his eyes and said, suddenly settled in shape, looking in the direction of the left-hand archives, here is only more than 30 meters from the archives of the straight line distance, is the real entrance there?

At this time, the old king lit a cigarette, tied the position of the cigarette butt with a rope, and carried it to the bottom of the well.

The white smoke on the smoke surface was blowing in the direction of the east side, although some of it continued to drift towards the wellhead, but more smoke drifted in the direction of the east-facing archives.

The old man looked at Zhou Hai and Hunan.

"Deputy Director Zhou, I will go down and see, this smoke is flying in a fixed direction, which means that there is air circulation here, the Germans pay the most attention to underground fortification construction, and ventilation is the first priority, so safety is no problem."

Before Zhou Hai's statement, Hunan could not help but push away the Zhouhai in front of him.

“I’ll go down with you!”

She tugged at her wrist.

"Anyone can go down you can't, you still have Hu Lao to take care of, your safety is the most important at this time."

Xiao Liang looked at Hu forensic, I followed the old king with the crazy, the fat man was responsible for contacting Huang Zhongsheng, and in addition, Xiaohu told Xiaohu to pursue, where was the land in the three courtyards before liberation?

Who uses it?

It has been to be recalled that when the Germans were there in 1900, if they were uncertainly consulted with Hu, she seemed to know in detail about that history."

He said that he did not wait for the fat man to reply, threw the survey box at the wellhead, and followed the old king to climb down the iron ladder.

Although Zhou Hai's words are not tough and do not have a high tone, but Hunan thought that he did not insist on it, and indeed he could become a burden, or honestly wait.

The fat man next to him was in a hurry, pacing and calling, urging Huang Zhongsheng to their speed.

In addition, the continuous emphasis on lighting facilities, after all, looking at today's state seems to be outdoors overnight, then they need a lot of lighting equipment.

After arranging these, I found that Hunan and Xiaoliang had already fallen on the wellhead, Hunan's face was not hidden, and the fat man's lips seemed to be a little mean to Haizi.

At this time, the three people have gone down to the bottom of the well, Zhou Hai and the crazy survey box has been down, of course, the fat man's camera also directly brought down, the madman will cross the camera around the neck.

The old king has investigated a circle and said: "Here is a rectangular channel gathering port, now there are three directions with the channel, we choose which one to go?"

The madman exclaimed.

“Three?”

Zhou Hai clicked on the mobile phone to find the compass in the direction, it seemed that this position was close to the wellhead, and he could also receive a signal and look at the channel on the west side pointing towards it.

"We go to this direction first, this side is the archive room, I always think Yang Duxiu chooses here must have his intention, but we did not find the reason."

The old king has simply checked the passage, in addition to dirty, there is no problem in the air here, and no organ has been found, looking at the piles of earth piles and broken bricks at the entrance of the passage, as well as the traces of the soil remaining in the walls of the passage.

He squinted his eyes, as if the passage had been blocked.

Only see the walls inside the passageway, are masonry arched buildings, the height is more than two meters five, the width of two meters, not to mention the people, is to carry what big things can pass.

“Let’s go to the west!”

With that said, the old king raised his hand to the west side of the passage, and did not forget to take the Zhou Hai hand's survey box on his body, and the three of them walked toward the passage.

Although the light is not very sufficient, the three people can also feel that the passage seems to go deeper and deeper, and no steps are just changes in the height of the ground.

The madman swallowed a mouthful, the voice was a little trembling, after all, the environment was too gloomy and terrible.

"How come we go lower and lower, is there another layer here?"
