Fang Bu didn't care that there was still thick smoke and kept drilling into the pipe, jumped up, grabbed the edge of the vent, held his breath, and put his head into the vent.

There were two more coughs inside, and listening to the location, the person was in a horizontal pipe about twenty meters away from here.

If you do the math, you'd have crawled past the entrance of the hallway, four rooms away.

Fang Buwei jumped down again and glanced at the vent that could just reach into a head.

The transverse ducts are specially designed for the middle two rows of windowless rooms, and are indeed connected to the current square room.

The horizontal pipes can indeed climb into a person, but the longitudinal pipes leading to each room can only stick into one head, and they are made of steel plates, so people can't climb out at all.

At that time, when choosing a room, Fang Buwei was afraid that the Japanese spies would still carry some strange weapons, such as poison gas cylinders, so he chose a room with a window.

But he didn't expect that the Japanese would really think of taking advantage of this.

There are too few trustworthy manpower, so Fang Buwei has no way to arrange in advance, so he can only hold the main position without losing, and then see the move.

It seems that the Japanese wanted to listen through the ventilation ducts to confirm which side the main characters were.

"Go, notify Captain Ye in room 402 and ask him to send a few people to light fires and smoke in the bathrooms of each room...... Be careful not to cause a fire! ”

Fang Buwei changed his clothes, went out of the bathroom, and confessed to a bodyguard.

"Woo woo wow......" Yin Zhiwen rubbed his eyes and sat up, not knowing what to ask?

"Woo woo wow la......" Seeing that Fang was not a little confused, Yin Zhiwen said again.

Although Fang Buwei didn't understand it, he could distinguish it, and the content of the two sentences that Yin Zhiwen said before and after was different.

"Sleepy?" Yu Erjun sat up, looked at Yin Zhiwen and asked, but the other party didn't say, "He's asking if you have any movement again?" ”

It turned out that Yin Zhiwen was in a daze and spoke Malay.

"The Japanese got into the ventilation ducts......" Fang Buwei explained.

At this time, there is no need to conceal it at all, and it is necessary to let Yu Erjun and Yin Zhiwen know the seriousness of the situation, as well as the all-encompassing and all-pervasive means of the Japanese spies, so as to increase their vigilance as much as possible.

"The Japanese are so powerful?" Yin Zhiwen exclaimed.

Yu Erjun squirmed his lips, but the words of thanks were not said in the end.

He now finally understands the truth of the phrase "great grace does not say thank you".

After tossing twice in a row, the people in the room no longer had the intention of sleeping.

It's okay if the others don't sleep, but the three bodyguards who change shifts have to sleep.

Fang Buwei took out a bottle of medicinal wine from Yu Erjun and threw it to the bodyguards, asking each of them to drink a little.

Fang Buwei returned to the end of Yu Erjun's bed, Yu Erjun said that he couldn't sleep, he wanted to get up and sit for a while, and let Fang Buwei sleep for a while.

Fang Buwei shook his head and refused, where did he have time to sleep?

Thinking about the more than ten days of sailing, Fang Buwei had a headache.

The system doesn't say that it is to prescribe a bottle of energy potion and let yourself drink it.

Fang Buwei secretly complained and turned on the system.

It will be more than one o'clock, and with the fact that he has just thwarted the other party's two actions, the Japanese spies on the ship should have made some moves.

He took out the transceiver that he had left and turned on it for a few seconds.

There are powerful radio waves, but they are basically the same type of code, which should be used on board to ensure that there is no deviation in the direction of sailing.

There are also radio waves received, but most of them are chaotic and disorderly, erratic, and extremely brief.

This should have floated over nowhere, and it didn't make much sense.

Fang is not waiting for continuous, but regular radio waves.

If the Japanese on the ship send a message, as long as they open the props, they will definitely receive it as soon as possible. If it is a signal from Shanghai or the spy headquarters in Japan, even if it is far away and difficult to receive, it will certainly not be chaotic.

At least the system can tell if it is sent back at the same frequency.

After waiting for almost a minute, the transceiver did not move, so it was not turned off directly.

Counting it, with the addition of new props, it only takes 30 minutes to save a little.

The party does not decide to listen every five minutes, and each time it is controlled within five seconds.

He did not believe that the Japanese on board could withstand the failure of the operation for three or four days without reporting to the headquarters.

Because of the distance, no matter which party sends, it is not sure whether the other party has received it, and it must be sent again and again.

On the ship, there is no need to worry that the enemy will detect the radio and expose it, so naturally there is no need to be as careful as in the enemy war zone.

Fang is not to infer that as long as you start sending, don't send dozens or hundreds of times, until the other party confirms receipt, no matter which side of the Japanese will not be willing, five minutes is not enough.

After turning off this transceiver, Fang Buwei researched a new prop.

The previous one had already taught him a lesson. The system is more pitty than that, when giving props, it doesn't even prompt that the road has hidden attributes?

As soon as he opened it, Fang Buwei was taken aback.

I didn't look closely when I received it, but in addition to the old functions of sending and receiving compilation, this thing can interfere with radio waves in a certain area.

And it's not a hidden attribute, so you don't need to spend points.

There are indeed hidden attributes.

The pro-prop has the function of radio wave positioning, but the specific positioning distance can only be known when you redeem it with points.

There are not many points redeemed, and one time is ten, which can last for ten seconds.

Good stuff!

Fang Buwei was overjoyed in his heart.

Since the first level has been upgraded, the pit ratio system has become more and more user-friendly.

Whether it is listening or direction finding, the time of the previous props has not run out, so Fang Buwei put away the new props first.

After that, Fang Buwei listened continuously for more than an hour, and the effective time of the transceiver was used for more than a minute, and the time was already three o'clock in the morning, and still no signal was detected.

Did you make a mistake in your own inference?

As soon as this idea came up, it was rejected by Fang Buwei.

The Japanese have a very big plan, and if they can set up such a big situation, those who draw up plans and plans must not have imagined that all kinds of accidents will occur, and they will certainly arrange in advance the means to be able to contact the headquarters in a timely manner.

I really had to wait for the ship to dock before sending a telegram, and the daylilies were cold.

Fang Buwei still followed the plan and continued to listen.

During this period, the bodyguards in charge of perimeter patrols have come in three times in a row to report at the door, saying that everything is normal in all rooms and corridors.

In this case, in addition to the three bodyguards who were hypnotized after drinking, Yu Erjun, Yin Zhiwen, including Xiao Zaiming, where could they sleep.

Yu Erjun didn't want to drink, but Yin Zhiwen couldn't drink, so he could only sit with big eyes and small eyes.

They originally wanted to chat, but Fang Buwei sat flat and steady, and he didn't move a trace for two hours, thinking that Fang Buwei was asleep, and no one wanted to make a sound, for fear of waking him up.

Yin Zhiwen couldn't help it, and quietly asked Xiao Zaiming: "Brother Xiansheng is really in the seat, he is from Taoism?" ”

Although he doesn't sit down, he often makes a salute, and if he sits on his knees for an hour at most, he will not be able to stand it.

Fang Buwei can sit for a few hours, and it is the same as iron?

Among these people, only he may be able to see how powerful Fang Buwei is.

"It's not!" Xiao Zaiming replied vaguely.

Fang is not a fart seater. But being able to sit for such a long time, Xiao Zaiming also felt very strange.

"It's still a great brother, I can cultivate a genius like Xiansheng, brother, I really want to ask for advice......"

Before Yin Zhiwen's words fell, Fang Buwei stood up fiercely.

"Woke up Hyun-sang?" Yu Erjun glared at Yin Zhiwen dissatisfied.

"No, I'll go out for a walk!" Fang is not a return.

After waiting for half the night, there was finally movement.

An airwave signal has been detected.

There was a signal from the ship, but it was not consistent with the fixed navigation radio waves, so it could only be sent by Japanese spies.

At the same time as detecting the radio waves, Fang Buwei directly turned on the interference function of the new prop, and he could also use the previous radio wave direction finder.

The location shows that it is nearly two hundred meters away from this room in a straight line.

Isn't it to the stern of the ship?

The ship's radio is in the cockpit of the bow of the ship, and this signal is in the stern, which means that their inference is correct, and the Japanese really brought the radio on board.

So how did their antennas stand up?

According to Qi Zhenjiang, two thousand miles, that is, a transmission distance of one thousand kilometers, the antenna must be at least seven or eight meters.

Doesn't that mean that the radio stations used by the Japanese to send telegrams have to be more than 20 meters away from the antenna?

The more Fang Buwei thought about it, the more curious he became.

"Did Brother Xiansheng find out something again?"

Yin Zhiwen flipped his seat and asked excitedly.

Fang Buwei shook his head calmly: "No, it's just a regular inspection!" ”

Yin Zhiwen still wanted to ask, but Fang Buwei had already left the room.

He casually walked into a room with a window, and before turning out the window, he deliberately checked the equipment on his body.

Two guns with full magazines, three daggers, and two thin steel wires of different lengths......

Fang Buwei stood at the window, listened quietly for nearly a minute, and only after making sure that there was no unusual movement outside, did he turn out the window.

From this floor, you can climb to the fifth floor, and you can even climb up to the fifth floor to reach the observation deck, but Fang is not afraid of waking up the guests in the luxury cabin, so he climbs the window eaves less than two fingers wide, and his hands are in the air, and he moves directly to the bow of the ship.

When he was about to get to the location of the restaurant, Fang Buwei climbed to the fifth floor and climbed to the observation deck.

The observation deck at night is enclosed and there is certainly no one on it.

Fang didn't let himself make a movement, and walked lightly to the stern position.

When he found the location of the radio station according to the prop positioning, he was startled, and at the same time cursed in his heart.

No wonder the Japanese sent a telegram so late?
