Lao Zhang is an old underground party, and he knows quite a lot about tracking and anti-tracking methods. Therefore, when he found that Miyamoto Ranko was walking slowly after walking out of the teahouse, he immediately stopped the other four comrades who were eager to try with his eyes, and told them not to follow for the time being.

Obviously, this 'ghost' is very cautious and vigilant, so she can't follow her immediately, otherwise it will be easy to expose someone who is following her, so that the 'ghost' will be aware.

When Miyamoto Ranko had already walked away, Lao Zhang signaled the comrade in charge of tracking the first section to start following on foot, and at the same time immediately signaled another comrade to follow behind the first comrade as a person who could be replaced at any time.

When Miyamoto Ranko and Masao Yamashita were meeting in the private room, Lao Zhang had already called the four comrades to a place far away from the entrance of the teahouse and told them that the target was a woman in a cheongsam. At the same time, in order to prevent the other party from being aware, Lao Zhang also formulated a strategy, that is, to track in segments and would rather lose the target than let the other party be aware of the situation that someone is following him.

Lao Zhang knew very well that this Japanese hidden spy had been lurking in the mountain city of Chongqing for many years, and knew that he had only recently discovered a hint by Li Yixin, which from another point of view, showed how cautious this Japanese hidden spy would be in normal times, otherwise he might have been discovered in this environment where the spies of the military and the central command were all over the city.

And since Yamashita Masao has also come to Chongqing, it is impossible to only meet this Japanese female spy once, if you really lose this Japanese female spy today, don't be afraid, just keep an eye on Yamashita Masao to have the opportunity to track down this mysterious woman again.

Miyamoto had been walking so slowly for a long time, she had been secretly observing behind her several times, and everything seemed normal, and the pedestrians who were walking at a normal pace overtook her one by one and walked straight to the front.

But she still did not dare to be careless, but suddenly stopped in front of a small stall selling flowers, and paid for a small handful of yellow horn orchids, which she glanced in the direction she came from, intentionally or unintentionally, as she paid.

At this time, the first underground party member who followed him happened to overtake her at the speed of normal walking, and turned into the alley at the mouth of a small alley not far ahead.

He really didn't attract the attention of Miyamoto Ranko, who thought he was just an ordinary pedestrian and immediately ruled out the suspicion of tracking. And the second underground party that set out to follow Miyamoto Ryoko has been walking towards Miyamoto Ryoko at the walking speed of a normal pedestrian.

Miyamoto didn't think there was a 'tail' behind her until this time, and she took the yellow horn orchid to the road again, but she was walking fairly fast now, which was her second anti-tracking tactic.

Generally speaking, if someone is following her behind her, as soon as she suddenly spends up speed, she will inevitably speed up her walk in order not to lose it, so that she can easily find out if there is a stalker behind her.

But the underground party that followed Miyamoto Ranko in the second line firmly remembered Lao Zhang's instructions when he assigned the task just now, and did not speed up the pace of walking, but walked forward unhurriedly at the original speed, even if he watched Miyamoto Ranko get farther and farther away from him.

Miyamoto Ranko walked in a hurry for a while, not noticing that one of the pedestrians behind her suddenly followed her and accelerated his walking, so he really put his mind at ease, thinking that there was no danger for her to venture out to meet Masao Yamashita today.

So Miyamoto Ryoko immediately summoned a sliding rod, told the pole the destination, and got on the sliding rod and rushed to her residence. Time was already a little tight, and she had to go back to her apartment and change into the same clothes as she went to work.

The underground party behind him was not mentally prepared for Miyamoto Ranko's sudden move to move the slide rod in advance, so he could only brush his hair with his hand, signaling to the comrades behind him that he would stop following and need to be replaced, and then turned right and walked into another side street.

The third underground party also followed, and when he saw the signal from his comrades in front of him, he immediately followed, keeping his eyes fixed on the slide.

In this way, when all four members of the underground party had completed a part of the journey and were replaced by Lao Zhang's personal tracking, Miyamoto Ryoko slid the rod to the destination, got off the sliding rod and paid the money, and then walked into a small alley.

Lao Zhang didn't follow immediately, but still walked unhurriedly to the place where Miyamoto Ranzi slid the rod, pretending to look up at the sky unconsciously. There was a sign hanging on the wall at the mouth of the alley with the name of this small alley, and he was actually looking at the name of this small alley.

Lao Zhang has been lurking in Chongqing for many years and is very familiar with the road conditions in Chongqing. Most of the alleys like these are connected to rough stone paths, but they are narrow and few pedestrians.

He didn't dare to follow Miyamoto Ranko into such a small alley, because it would be too easy for Miyamoto Ranko to find out that someone was following him.

And most of such alleys are filled with various households, and an unfamiliar face is very eye-catching when you walk in. Lao Zhang did not stop when he passed by the alley, but continued to walk, looking for a suitable place to stay normally, so that he could stay and monitor the alley.

Because he thinks that this mysterious Japanese female spy has a very high probability of living in this small alley, he has to find a place where he can keep an eye on the mouth of this alley and prepare to monitor this place for a long time. Lao Zhang believes that if this Japanese female spy lives here, then she will definitely come out of the alley again, even if it is not today, it may be tomorrow or the day after tomorrow.

Lao Zhang continued to walk forward, and he saw a small noodle stall on the side of the street in front of him, which was found in the streets and alleys of Chongqing, so he walked over and asked for a bowl of small noodles, ready to eat it slowly while monitoring the mouth of the small alley.

But it backfired, no matter how slow Lao Zhang's noodles were, there was always a time when he finished eating, and after eating the noodles, he didn't have any reasonable reason to continue to sit at the small table of the small noodle stall, so he had to leave.

Fortunately, Lao Zhang had already determined that this place was most likely near the residence of the Japanese female spy, so he decisively left the small noodle stall and went to meet the four underground party members who had already arrived here.

Since these four comrades had already met with the target when following the Japanese female spy today, in order to prevent the Japanese female spy from recognizing these four comrades, Lao Zhang decided that tomorrow's surveillance of this alley mouth must be replaced by a new batch of unfamiliar faces to secretly spy on this Japanese female spy.
