In my previous life, when I watched TV, I often saw the guerrillas hiding the entrances and exits of the tunnels in such places. Fang Buwei has always been skeptical, thinking about the fire in the furnace that is obviously so big, how did people get into it?

This time it was an eye-opener for him.

It turned out that the furnace teeth were braided in whole with iron bars. There are two ears hidden at both ends. After the cauldron is removed, two sticks of firewood are inserted into the iron ears of the furnace teeth, and the entire furnace teeth can be brought down, because the weaving is dense, and the ashes inside will not leak down.

After the person enters, he puts down the teeth of the stove and pokes the ashes at the bottom of the stove, and a thick layer will fall, and all traces will be covered.

Fang Buwei slapped the dust on his body and went to the yard again.

Low earthen walls, the roof all covered with branches, and covered with mud. Most of the rooms have no windows, and once you enter, you feel like a dark winter.

It was here that the short-haired woman was caught.

Fang Buwei walked out of the yard and stood in the alley.

He roughly estimated that the straight-line distance from the two small buildings was about 100 meters.

Counting from the head of the alley, this yard is the second. The previous one, like this one, was secretly bought by the Japanese.

There was a commotion in the courtyard. One of Li Wuxi's subordinates and several team members have almost demolished the houses in these two courtyards.

Again, not to mention gold, not even a single chicken feather was found.

According to the confessions of the Japanese gunmen who were caught, they usually hid here, and when they went in and out, they dressed up as coolies, and never entered and exited those two small buildings.

Fang Buwei looked at the two dilapidated courtyards. Both the house and the yard were in shambles, and many places were dug up. A group of agents commands coolies to carry sand and broken waste.

Seeing this, Fang Buwei was even a little discouraged.

The secret service doesn't eat dry food, knowing that there are tunnels, how can you not think of digging three feet into the ground?

If you can find something useful, you should report it a long time ago.

"Team Leader Zheng, ask for something!" Fang Buwei found the subordinates who Li Wuxi arranged to be in charge here.

Zheng Litao is the deputy head of the Intelligence Section, and he knows that Fang Buwei has been promoted to the head of the Operations Section, and he is also very valued by Director Ma, so he does not dare to slack off at all.

"Team Leader Fang, what do you command!"

"I can't talk about orders!" Fang Buwei smiled politely, "I just want to ask who lives around here, have the brothers asked?" ”

"How could you miss it!" Zheng Lixin replied, "Last night, Section Chief Li took his brothers to check, and they were all a group of coolies......

Fang Buwei nodded.

He was thinking that the Japanese could buy the first two yards, and they could also buy the third and fourth. If nothing else, it's okay to use it for Tibet.

Fang Buwei walked down the alley, watching carefully along the way.

The driver had been down the alley yesterday, and he wanted to see if the driver had deliberately dropped something.

When he walked to the fourth house, Fang Buwei glanced at it unintentionally, and found that the courtyard of this house was a little high, and the color of the earthen walls and roofs was not the same as the others.

He subconsciously walked in, and there was no one in the yard or in the house. Fang Buwei took a turn inside and out.

Like the other houses in the vicinity, the roof was covered with branches and covered with mud. But although the leaves on it are dry, they are very neat, and it looks like it has just been built.

"Go and ask, who lives in this house, have you checked it?" Fang Buwei said to the subordinates who followed behind.

After a while, his subordinates ran back, and Zheng Litao.

"I've checked, it's an old man behind the ear!"

"What about people?" Fang Buwei asked again.

The old man's ears were back, and he couldn't hear two of the three questions clearly. I asked the neighbors nearby, and it was indeed an old resident here, so I let him go......"

"What does the old man do?"

"Say it's begging on the street!"

"Did you see him today?"

"I really didn't pay attention to this!" Zheng Lixin replied.

"I'm sorry for Team Leader Zheng!"

After asking, Zheng Litao went back to digging for gold.

"You go and look on the nearby street, see if you can find the deaf man, and bring him ......back when you find it," Fang Buwei explained to Bai Dashan.

Fang Buwei wanted to find someone to ask, but there was no figure in the alley.

The children who were playing and the old people who were basking in the sun were gone, and the doors of every house were closed.

In this day and age, ordinary people are afraid when they see a soldier, let alone a spy.

Fang Buwei quickly turned around before he found an old man who looked at him without shivering.

"Uncle, whose house does this house belong to?" Seeing the old man's scared look, Fang Buwei tried his best to pretend to be kind.

Zhao ...... Zhao Er's family! The old man replied.

"What about others?" Fang Buwei asked again.

"I said I went to Tianjin to do business, and I haven't seen him for a year!"

"When was this house built?"

"At the beginning of spring last year, after repairing the house, Zhao Er ......left," the old man replied.

It takes about the same amount of time as the driver to confess. He was sent to Nanjing by the Special Science Division a year and a half ago, and then looked for a suitable place to buy the two small buildings before the Chinese New Year. But the tunnel was not dug by him, and by the time the special high-tech informed the receiver of the tunnel and the two courtyards, the tunnel had already been dug.

"Then who is the old man who lives here now who is Zhao Er?"

"What is the deaf man you are talking about, sir?" The old man replied, "It's been more than a year since I came, and I have no children and no daughters, and I have been begging for food on the street. I built a shack at the head of the alley before, and I was dazzled and deaf, Zhao Er saw that he was pitiful, and asked him to come and see the house when he left......"

Fang Buwei asked a lot more, and finally gave the old man a few copper plates, and the old man left with a smile.

Fang Buwei looked back, Zheng Lixin was digging in the yard with people, and he didn't pay attention to him. But he was still not at ease, so he deliberately went around and climbed into the yard from the back wall.

He took the axe and came to the middle of the courtyard, and chopped two axes in the clearing, revealing the sand and gravel inside.

It turned out that the Japanese had poured all the soil dug out of the tunnels here.

After entering the tunnel before, Fang Buwei was still thinking, the tunnel is not short, and the Japanese want to hide people's ears, which must take a lot of time. Because it is a big trouble to transport so much sand and gravel dug up.

Now is not the previous life, there are so many means of transportation, and whether it is those two buildings or this narrow alley, at most you can get a trolley in. Sand can only be transported by manpower.

But if you build a new house not far from the tunnel while digging the tunnel, you will solve this problem perfectly.

There must be something wrong with that Zhao Er. I just don't know if I was killed by the Japanese or fled.

Since it is inseparable from the Japanese, it is impossible for the Japanese to leave such a courtyard in vain.
