After all this, the three of them returned to the phone booth and found that Moriyuki had returned. When she saw the three of them, she immediately asked, "Where is the recorded time?"

"Here." Wei Dingbo handed the book on it.

“Accurate?”

"precise."

"You guys go back and rest."

"yes."

Wangyuezhizi hurriedly left with the quilt, while Wei Dingbo and the other two went towards Li Qian's residence. On the way, Wang Muyan couldn't help but ask: "What's the use of this?"

Wei Dingbo was actually thinking in his heart, and he didn't know what Wangyue Chi-sen did or what the purpose was.

But he vaguely felt that things were not simple.

Pull the switch?

electricity?

Suddenly, Wei Dingbo had some problems in his mind, but it was not very clear.

As for Li Qian, he didn't know why, but just said: "Just complete your task."

When the three of them returned home, Wang Muyan asked, "Do you still need to take turns to watch?"

"No, do some mechanisms behind the door. As long as someone comes in, you can send a reminder." Just take turns to show your attitude. After observing the first night, it is safe to do some mechanisms to rest tonight.

"Okay, I'll do it."

Today, Wei Dingbo was not in the mood to chat and went back to the room to rest early. In fact, he was lying on the bed and recalling carefully what he did today.

Pull the power switch to cut off the power in the house in Shoushanli.

What is the purpose?

In fact, the first thing he thought of on the road was the radio detection vehicle. He always felt that if the radio detection vehicle wanted to take action, it would have to rely on the power of Wuhan District. Then, if they were arranged by Yao Yunbo to perform tasks in Wuhan District, would it be a task related to radio detection? In other words, the goal of this mission is infinite radio station.

Wei Dingbo is only good at using the radio station, and he doesn't really understand the structural principles. He also has only a slight understanding of the radio detection vehicle. He can't even understand what the internal structure is.

But I had a rough talk about it when I was on the boat. The radio detection vehicle could capture radio stations, but there was a necessary condition that the radio station must be working.

Radio station work requires electricity, and today, Wangyue Chia lets them lose power.

So could it be that the Japanese radio detection vehicle monitored on Yiyuan Road, thus capturing the radio signal activity in the Shoushan, but the Japanese radio detection vehicle that was too far away could not be locked in the specific position, so it could only enclose a large area like that of Shoushan.

So they need to use a method to lock in where the radio station of the Anti-Japanese Organization is.

The solution is what Wei Dingbo and the others did tonight.

The reason why Makoto Mako asked them to guard the phone booth was because she wanted to start sending messages on the radio station and was caught by the radio detection vehicle, she asked them to start pulling the switch.

At the same time, let them record the exact time.

The radio detection vehicle can always capture the radio signal in Shoushanli. When the radio signal suddenly disappears, the radio detection vehicle cannot capture it.

Under what circumstances does the radio signal disappear? Naturally, when the radio cannot work normally, it is similar to a power outage.

So the Japanese plan to lock the radio in a certain building in this way to narrow the scope of doubt.

As for why Wei Dingbo and his friends were not allowed to pull the switches one by one, it was because the range was too large and they were pulled the switches one by one. Maybe you had not found a place, and the radio station of the Anti-Japanese Organization had completed the sending of the report and stopped work.

But as long as the scope is successfully narrowed first, the next time it may be in this building, one by one, and the other may be to pull the switches one by one in the building.

Wei Dingbo had to get nervous when he figured out these things. He didn't know if the Japanese could lock in the radio station of the Anti-Japanese Organization tonight, because there was a problem here, that is, the radio station was most likely to work with batteries.

But this idea has a certain sense of luck, because the radio stations in the concession are generally fixed, after all, the concession is safe and there is no need to transfer it.

Then, when sending the report, the battery is basically not used, so the power supply in the house will affect the use of the radio.

Wei Dingbo wanted to send the news out at this time, but one problem he faced was that he could not let Li Qian walk around at will, which was equivalent to restricting his own actions.

He just carried out the mission tonight, and on the second day he left alone, and didn't stare at Li Qian, let alone protecting him, so what did he do?

So now it becomes extremely difficult to send messages. Fortunately, even if it is locked tonight, it is just a building. It may take some time to lock it to a certain household.

After all, in the French Concession, Wuhan District did not dare to go to the door for big fanfare. Those residents only needed to call the police, so Wei Dingbo and the others would feel uncomfortable.

This is the only good news now.

Moreover, Wei Dingbo believed that it would be not for a day or two for the radio detection vehicle to stare at Shoushanli. After all, tonight, the son of Wangyue informed them of their actions first and asked them to wait in the phone booth.

Then the radio detection car started to capture the signal. At the same time when they captured the signal, they asked Wangyuezi to notify Wei Dingbo and the others to start pulling the switch.

This situation is enough to show that the Japanese have already grasped the time of the Shoushan Rinai radio station.

Because it takes a fixed time for a radio station to send or receive a telegram. After all, this is not an open public radio station, and it is impossible to work on standby all day.

Radio stations in intelligence work will have a specific time to send and receive telegrams. After several days of monitoring, the radio detection vehicle has already mastered this information.

Wei Dingbo is unknown whether the special nature of today is the days apart, the day of each month, or the day of the week.

But he believed that the radio stations in intelligence work could not be operating every day, and there would definitely be no movement tomorrow, and there would be several days at this interval.

That is to say, it will take several days for the Japanese to close the power switch of each household and lock the radio station next time.

Wei Dingbo was not too anxious when he thought about all this in his heart. After all, the more in this situation, the less you should be anxious, otherwise it would be very likely to make a big mistake.

The news must be sent out. No matter whether the radio station is organized, the Military Affairs Bureau, or the Central Administration, it is not good news to be discovered by the Japanese.

But you cannot leave any doubts or handles, otherwise the consequences will be as serious as they are unbearable.

Wei Dingbo did not sleep soundly tonight. After all, it took a long time to figure out these problems. He wanted to thank the boy Wangyue explained the radio detection car to him when he was on the boat, otherwise he might not be able to react at all.

The rare things imported by the Japanese really have unexpected effects. The cars can find the radio station before they enter the concession.

If they were asked to enter the concession, wouldn’t it be more accurate to lock it? Maybe you were using the radio to send a message and the Japanese military police broke into the door.
Chapter completed!
