Fang Buwei went to Zheng Litao again.

"When you checked yesterday, how did you check it?" Fang Buwei asked.

"Surrounded by large forces, and then house-to-house searches...... In the end, the head of the unit was not at ease, and then cleared out all the residents in each alley, concentrated the guards, and asked them to identify each other...... The other group of brothers went in and searched again...... In the morning, everyone who left the area searched again......" Zheng Litao replied.

Carpet checking, the possibility of omission is very small. Stuff wasn't taken out.

Fang Buwei found the old man who had asked again.

"The third house is a half-old man who sells cigarettes on the street......"

It's a freelance job again.

He gave the old man a silver dollar and asked the old man to ask the neighbors if anyone had seen a deaf man begging for food and an old man selling cigarettes.

Half an hour later, the old man returned. They said that they were asking for food and selling cigarettes, but they left in the morning. At that time, there were soldiers guarding the entrance of the alley.

According to the driver's confession, the short-haired woman was only nominally his subordinate and was only responsible for providing him with funds for his activities. Nothing else will be reported to him.

Fang is not suspicious, that tunnel is very likely to be dug by a short-haired female spy, and even the driver doesn't know that the third and fourth yards are actually controlled by short-haired women.

Those two men are likely to be the subordinates of the short-haired female spy.

One asks for food, the other sells cigarettes, and they can run around the city without arousing suspicion.

Fang Buwei climbed in through the back wall again. First, he walked into the house. He wanted to find out if there was a tunnel in this courtyard.

After turning inside and out, looking at the wrong places, Fang Buwei knocked them all over, and found no abnormalities.

He went back to the second house and slipped through the stove into the tunnel.

Fang Buwei chopped with an axe for a while, and the tunnel did come to an end, and it did not extend into the courtyard next door.

Fang didn't miss anything for the total sense of self.

Fang Buwei turned back again, leaning against the wall, carefully looking at the layout of the newly built courtyard.

Next to the newly built courtyard, that is, the third one from south to north from the head of the alley, is also a broken house, and the one who lives is the one who sells cigarettes.

After Li Wuxian found out that the cigarette seller had nothing to do with the Japanese, he let him go, and the yard was not dug up.

There is a passage between the two courtyards, and the aisle is very narrow, at most one person wide, which is obviously the dividing line between the foundations of the two houses.

Fang Buwei looked at the aisle, and there were traces of water flowing inside. He looked again, and the house on the high ground had a drainage hole under the wall of the hallway. As soon as it rains, water will flow out of the drainage hole and into the aisle.

The dilapidated home was in disrepair, and the earthen wall facing the aisle had collapsed somewhat. And there was a gap right next to the drainage hole.

Looking at the traces, when it rained two days ago, the rainwater flowing out of the drainage hole flowed through the courtyard with a tunnel, but there was a collapsed earthen wall blocking it, and there was not a lot of water flowing through. Most of the water flowed down the aisle into the alley behind.

The area of the drainage hole is not small, and it is completely possible to drill into it.

Fang Buwei looked at the drainage hole, and then looked at the road, and a flash of light flashed in his mind.

Who will build a drainage hole under the wall of a neighbor's house?

This is a deliberate posture to find fault in any era, and it is strange that the two families do not break the bloodshed.

But the Japanese did just that.

There must be a problem.

Fang Buwei climbed into the new yard from the back wall, and was ready to search it again.

He came to the gutter first. Looking down, there was a stone slab underneath the drainage hole, which was used to prevent the sand under the base of the wall from being washed away by the water.

Fang Buwei pressed it, and the slate turned out to be loose.

He lifted the slab with all his might, and there was gravel underneath.

Fang Buwei held the axe and slashed a few times, and there was a muffled "bang", as if it had hit something.

He threw an axe and gouged the gravel with his hands. After three or four inches of planing, another plank was dug out.

Fang Buwei pulled off the plank, revealing a black hole underneath.

Take a flashlight, and it looks like a dark room underneath.

Finally found it!

Fang Bu was secretly excited.

The spies and gunmen who have confessed have not mentioned these two courtyards and dark rooms.

All the people living here are poor people, and they can't even dig a vegetable cellar, so it is impossible to build such a basement.

Nine times out of ten, this is where female spies use to hide their funds.

But now it's broad daylight, and there are so many spies nearby, if your movement is too big, you will definitely hear and reduce your voice.

Fang Buwei suppressed the excitement in his heart, and filled the excavated sand and gravel on it in three or two times, and covered it with wooden boards and stone slabs.

Looking at the footprints he had left, Fang Buwei jumped into the dilapidated courtyard and stomped heavily on the earthen wall, which fell down in response, and the clods of dirt covered the footprints he left at the drain.

He climbed with both hands and gently climbed up the wall again.

After going around in a circle, when he returned to the house where Zheng Lixin was digging, Fang Buwei saw Bai Dashan leading a few people back.

"Did you find it?" Fang Buwei asked by jumping off the wall.

Bai Dashan was chased by him to find that He deaf man just now.

"I searched all over the nearby streets, but I didn't find He Deaf!" Bai Dashan replied.

It would be strange if you could find it!

"If you don't find it, forget it!" Fang Buwei said indifferently.

Back at the exit of the tunnel, he asked Bai Dashan to bring him a chair and sat next to him to watch the coolies work.

Li Wuxian came and asked him if he had any discoveries, but Fang Buwei said no.

When it was almost dark, whether it was the small building or the dilapidated yard, nothing could be found.

Li Wuzhi withdrew the team, and left two or three spies on the construction site to guard the construction site.

Fang Buwei walked halfway, and asked Li Wuzhi to take a leave of absence to Su Minsheng on his behalf after he went back, saying that he wanted to go back to his uncle.

This is when I left the headquarters in the morning, I agreed with Gao Sizhong. But he's been there in the morning.

After Li Wuzhi left, Fang Buwei turned back again.

I was afraid that when I went back again, in case I ran into the spies who were guarding the construction site, Fang Buwei went to the ready-to-wear shop and bought a set of clothes that the coolies usually wear.

It's still early, and you can't go to the construction site. But he couldn't wander around the street, so he found a restaurant on the nearby street and opened a guest room.

He was going to go late at night, so he slept beautifully.
