The possibility of borrowing is not high. Tianfu is a very cautious person. He knew that once the passage is discovered, the secret service will inevitably conduct a large-scale investigation, and the source of the ship is a good direction.

The ship can only be his own, but the ship is not a small object. Wherever it is placed when it is not used in Tianfu, it cannot be brought back to his home. Then the fool knows that there is something wrong with it.

Hidden by the river after disguising it?

It is not a big problem to do this by the river in the wild, but it is not in the wilderness. This is a densely populated Jinling. There are residential areas along the river. There will only be two results for ships hiding by the river.

Discovered or stolen.

Looking at Tianfu's skillful entry and exit from Min Ping's residence, it means that he had a plan long ago, so the ship must have been prepared in advance. After hiding for so long, why wasn't the ship discovered?

"Bang."

Zuo Chong killed a mosquito parked on his arm. Looking at the faint lights on the Pearl River Road across the shore, he naturally thought of two possibilities: either the hull is small or the weight is light.

This is easy to understand. It is small in size and it will not easily attract other people's attention when hiding it. Please transfer it to a remote place to hide it. When it needs to be used, drag it to the riverside.

Or maybe both of these points are easy to hide and move. Is there such a water transportation tool? For example, the peasant woman who picks water chestnuts in the countryside around Jinling uses wooden basins as boats.

This kind of wooden tub can be used to take a bath and is a production tool when needed. An adult woman can easily carry it around the streets. This weight is even easier for a professional spy.

However, this thing is difficult to control, and even veterans will often overturn it. At the same time, its floating is more supported by water plants such as water chestnuts, and it is easy to turn the bottom and the sky on the empty water surface.

There is little possibility of using this tool in Tianfu. If he is a doctor who is carrying a large bathtub and is he afraid that others will not doubt it. The lurking personnel should try to keep a low profile.

What would that be?

Zuo Chong recalled various light ships, and soon thought of one thing, that is, a refuelable and deflated rubber boat. Only this thing meets the two characteristics of small size and light weight.

Since the emergence of vulcanized rubber technology in the first half of the 19th century, countless explorers and inventors wanted to use rubber to make ships, among which Britain conducted a lot of experiments in this regard.

According to the relevant information obtained by Zuo Chong, Dai Ying's imagination is still very big. For example, the cloaked rubber boat used for polar exploration is made of some rubber fabric, which is very light.

Before inflating, the cloak boat can be used as a rainproof awning. After inflating, it becomes a single-person inflatable boat. The bellows are only the size of a suitcase, and the cane and blades become rowing paddles.

After so many years of development, coupled with the technological explosion caused by the last war, there was even a double-person ship in a backpack. Although it was not as good as later generations, it was enough for Tianfu to use it.

(Pictures are in the easter eggs, not made up.)

This small river is not the Atlantic Ocean, and in the last century, four people crossed the Atlantic Ocean in rubber boats and successfully arrived in the UK from New York. Technically speaking, there is no problem.

And any technology is first used in the military. As an important part of war, the intelligence battlefield is also a test site for various new technologies. It is not surprising that the Japanese have rubber boats.

If Zuo Chong remembers correctly, in the future, Japan will rely on this thing to enter a no-man in the Jiangnan area with river networks in the future in the war of aggression. After capturing Tianfu, it can be used as a reference.

More importantly, through this point, another thing can be derived. There should be a car in Tianfu. The source is currently unknown. The car is different from a ship. The borrowing is not so conspicuous and abrupt.

The reason why he made this judgment was very simple. First of all, it was impossible for the other party to get here by a rubber boat from a very far place. The longer the distance and the longer the time, the greater the chance of being discovered.

It is impossible for the other party to go into the water from a very close place. The purpose of Tianfu establishing a secret passage to avoid possible surveillance. If he goes into the water on the other side of the river, what is the significance of this passage?

So he needs to transport the rubber boat from somewhere to the right place. There will be witnesses when taking a rickshaw. The motorized rubber boat that a bicycle may not be able to carry, and the most likely one is a car.

Zuo Chong raised his head and took a sip of cold water with the smell of vinegar. He sat on the wooden stake and raised his ears to listen to the movements around him, but he heard nothing except the cicadas that were ringing one after another.

Tianfu should have been evacuated. I think so, at most, he will do more investigations in advance. There is no need to stay for too long after completing the screening, unless he is sure that there is a problem and is ready to wait for the rabbit.

Zuozhong observed the trestle bridge through the hazy moonlight. This is a simple trestle bridge. The method is to penetrate two rows of wooden stakes into the water, and put wooden boards in the middle, so that there is a certain distance between the bridge deck and the water surface.

This is the calm inland river. If it is placed in the outer river with strong winds, a strong wind can overturn it, but this inconspicuous small pier has caused huge hidden dangers.

If Min Ping had not deceived Tianfu, then the only thing left to the intelligence department would be a cold corpse. Even if Min Ping had the opportunity to call for help, what would happen? If Tianfu dared to appear, he would definitely be prepared.

Fortunately, things have not reached that point.

Zuo Chong stood up with his knees on one hand and walked on the bridge. The bridge suddenly made a creaking sound. He stopped at the end of the pier, then lowered his head slightly and looked down at his feet.

There are no traces of water or traces.

It seems that Tianfu is very careful when landing and evacuating, or doing cleaning work during evacuation, which is a bit difficult. What he thought of before is speculation, lacking evidence to support speculation.

Without conclusive evidence, it is impossible to be 100% sure where this secret passage is. If you cannot be sure where this passage is, it means that Min Ping may face life danger at any time.

You can't let someone protect her in person. It would be better to give a sign to tell everyone that a Japanese spy was instigated by the Secret Service. At that time, Tianfu will be retracted and it will be difficult to find it again.

I thought about it for a long time.

Zuo Chong stopped his eyes on the dilapidated bridge deck and gently stepped on the hanging wooden board. If the traces of people cannot be found, then check the traces of the ship. No one can violate the law of material exchange.

When Tianfu went to see Min Ping, it was impossible to carry the rubber boat with you. The most likely thing was to buckle it on the pier. Will the friction between the hull and the wooden stake leave traces, and will the mud have scratches?

All these are possible, but there is definitely no way to investigate the scene now. At least it will take until dawn to send someone to search secretly, and to prevent Japanese spies from peeping around. This is not easy.

It is best to find evidence of the existence of the rubber boat from other aspects and where to start. With the cunning shown by Tianfu, there may not be too much evidence, unless it is a trace that cannot be removed.

Unclearable traces.

Zuo Chong is thoughtful, and the traces simply refer to the visible shadows or imprints that can be seen after things pass by, such as the traces of walking, such as the tracks of a ship, which can be seen with the naked eye.

In addition, there are traces that are invisible to the naked eye, such as sounds and radio waves. They need others and other carriers to be presented. Are there any traces of invisible existence that exist independently?

There is, smell.

The principle of olfactory is that tiny particles selectively block the nerve sensations of small holes in the olfactory sensory endings. These tiny particles cannot be seen under normal circumstances, but they actually exist.

How can Tianfu remove the odor and force the air on the air when it cannot destroy the on-site environment? But if you think about it this way, the other party seems to have another purpose to take the boat.

Did he want to use this method to avoid tracking police dogs? Unlike the police dog industry in the Republic of China, the Japanese began to cultivate police dogs very early, and it first began during the war.

The idea of ​​using water to block the tracking of odors in Tianfu shows that the Japanese spies are already conducting training in this area. The gap in strength between the Republic of China and Japan is really comprehensive, which shows that.

Thinking of this, Zuo Chong staggered and walked two steps, pretended to be drunk and sat on the ground, and then lay down directly. The part of the trestle that spanned the water was less than two meters, just enough for him to lie flat.

He sniffed against the cold and hard wood pillow. In addition to the smell of mud and rotten wood, a familiar and unfamiliar smell filled his nose, similar to the smell of tire rubbing.

To be precise, it was the smell of rubber paint. He had smelled it on a gas mask, which made Zuo Chong feel calm. Just like his own speculation, Tianfu was approaching Tangzi Lane with a rubber boat.

The secret passage can be determined.

Then now we can confirm two things: one is that the other party owns or can borrow a car, and the other is that the other party is indeed approaching Min Ping's residence through the river. These two clues are very valuable.

The number of cars in Jinling is quite small, most of which are used by the party, government and military organs. Public cars must have borrowed records, while the number of private cars is limited, so it is easy to investigate.

Just find the witnesses tonight and confirm the car model, color and license plate, and you can investigate the cars in Jinling. Another clue is added to search for Tianfu, and it is a direct clue.

As for using rivers as a passage, this method sounds good, but there is a problem that needs to be solved, that is, where to go and go, otherwise it will be useless if someone finds out.

This small river in Tangzi Lane leads to Zhongshan Road to the west and passes through the city area east. In terms of safety, Tianfu will not get into the water from the east. It is a downtown area, and there are many pedestrians now.

If someone who is too curious and calls the police after seeing Tianfu rowing in the middle of the night, how should he explain to the police station? Do you mean fishing? Tianfu won’t do such an inconsistency?

Only go west.

Zuo Chong slowly stood up and aimed at Zhongshan Road with his after-light light. There was a large bridge standing there. After crossing this bridge, he left the city area. The number of residents on both sides of the strait gradually decreased, which was very convenient for Tianfu to operate.
Chapter completed!
