Chapter 1186: Information about the future.

"Nani?"

"My opinion?"

Ozawa was confused. What opinion could he have? If it was a U.S. Navy ship, how could he tell us one, two, three, four, intelligence? He is really unfamiliar.

Zuo Zhong stared at him with big eyes and small eyes for a while. Seeing the guy's dull expression, he had no choice but to shake his head.

"Okay, I suggest that you and I act separately in the next step. You will verify the accuracy of the meteorological data, and I will be responsible for the hydrological data.

Your job is very simple. Try to collect newspapers from the past few months, and compare and verify them with the meteorological records and data above.

For example, from 1907 to this year, on the same date or month, do their rainfall, weather and other data have the same trend? "

Ozawakawa breathed a sigh of relief. If this was the case, he could indeed do the job. He was just reading the newspaper.

As for the "year-on-year" statistical method, he also learned it at the Etajima Naval War School.

Thinking of this, Ozawa said "Hai" confidently, and even showed his subjective initiative by proposing that the broadcast data every morning could be included.

Every morning at 8 o'clock, Oahu's radio will forecast the temperature and weather of the day. This is first-hand information and is highly accurate.

"Yoshi, Ozawa-kun, you said it very well."

Zuo Zhong said perfunctorily that weather records would be enough. Anyway, it was not a surprise attack on Pearl Harbor by the Guo army, so the data did not need to be too accurate.

Feeling good about himself, Ozawa immediately smiled, paused and asked Zuo Zhong how to verify the hydrological data.

Hydrological data is different from weather data. Measuring water depth and underwater topography requires professional equipment and a lot of manpower and material resources.

Now there were only two of them on Oahu, and it was not convenient for the consulate staff to intervene. He really couldn't think of how the other party would verify it.

So he tentatively asked: "Nan Jiajun, should we ask Tokyo for tactical guidance?"

Tactical guidance, this little word is too Showa-flavored, Zuo Zhong thought and shook his head again, looking towards the sea and said lightly.

"Don't worry, the hydrological data will not change much in a short period of time. You only need to select a few key points for verification to know whether the data is accurate.

Take water depth and underwater terrain, which are the most difficult to measure, as an example. Measure one or two points and compare them horizontally with the data in the data. Leave the rest alone for now. Do you understand? "

Ozawa no longer had any doubts and respectfully expressed that he understood. He sighed in his heart that he was worthy of being an elite in the military, but he was more professional than those guys in the extra-high-level courses.

At this point, the two clarified the next action plan and division of labor, and then started taking action separately.

In the next few days, Ozawa bought a large number of old newspapers from grocery stores and thrift stores that sold newspapers, on the grounds that he was studying the business situation on Oahu.

This kind of thing is very common in Hawaii, which has a strong business atmosphere, so it didn't arouse anyone's suspicion. Even the newly recruited store clerk didn't care. Everything went smoothly.

After preliminary statistics, Ozawa found that except for the hurricane season from April to November, the local weather conditions are very stable, which is good news for him and "Nanjia".

While Ozawa was busy, Zuo Zhong was not idle either.

In a Japanese-run fishing tackle shop, Zuo Zhong and the owner drank Japanese matcha and discussed recent news about Oahu and the world.

"Nan Jiajun, have you heard? Washington will allocate 40 mothballed destroyers for modernization and modification to strengthen the Atlantic Navy. Hawaii may also have a large-scale increase in troops." The owner of the fishing tackle shop revealed a piece of news with a smile.

The increase in troops means that more soldiers will come to the island in the future, and the business of the merchants will be more prosperous. It is not surprising that this person showed such an expression.

"Activate the mothballed destroyer?"

Zuo Zhong put down the tea cup in his hand, pondered for a moment and said: "The Germans have swept through Western Europe, and now only Britain is left to support the war situation alone. Washington naturally needs to be more vigilant."

After expressing his views on increasing the number of troops, he changed the topic and quietly brought the topic to business. After all, war should not be a businessman's concern.

But the owner of the fishing tackle shop seemed to be very interested in the military. He looked inside and outside the shop, and after making sure there was no one nearby, he said mysteriously.

"Washington's actions are not only to deal with the Germans, but also to prepare for Tokyo. The Red Mountain near Pearl Harbor has been hollowed out, and fuel used by warships is stored in it."

!!!

Zuo Zhong was stunned. He knew that the Americans underestimated the enemy, but he did not expect that they underestimated the enemy to this extent.

The location of the strategic fuel oil depot is a top secret among top secrets. Why would it be told by a fishing tackle shop owner?

And even the other party knew about it. He believed that it wouldn't take long for the entire residents of Oahu to know that there was a fuel warehouse in Red Mountain. Damn it.

After a long silence, Zuo Zhong revealed the purpose of his visit. He planned to rent a fishing boat to go fishing through the owner of the fishing tackle shop, but in fact, he was going to verify some hydrological data.

The owner of the fishing tackle shop patted his chest and assured that there would be no problem. At the same time, he confidently told "Minami Kaichiro" that except for the waters around Pearl Harbor, he could go anywhere he wanted.

This is not surprising to Zuo Zhong. No matter how hard the Americans pull their hips, they will not let go of the Pacific Fleet's station, but this is only a small problem.

Since the materials in the library were there, he only needed to measure the data in the unconfidential area to see if there were any big changes. There was no need to risk entering the confidential area. Seeing that the operation went smoothly, Zuo Zhong smiled and toasted the owner of the fishing tackle shop, and suddenly asked curiously whether the American sailors in Pearl Harbor had bought fishing tackle in the shop.

Talking about this matter, the owner of the fishing tackle shop proudly said that not only ordinary US Navy soldiers would buy it, but even officers of the Pacific Fleet were his regular customers. These people often spend time fishing on the docks and in the military port.

"Oh? Did they gain anything?"

Zuo Zhong looked at the other party curiously, seemingly asking accidentally, but his ears perked up.

"Mahi-mahi, a very delicious fish, with sweet taste and firm meat."

The fishing boss replied without hesitation and licked his lips after speaking, thinking that this kind of fish tastes really good.

In just a moment, Zuo Zhong's information flashed through his mind.

Mahi Mahi: A large oceanic, brackish water fish that swims rapidly. It generally inhabits the surface of the ocean. Its active water depth ranges from about 0 to 15 meters. It has strong adaptability to temperature and can tolerate low temperatures of 16°C and 21 to 30°C. The water temperature is very active in the sea.

It can be inferred from this clue that even if redundancy is taken into account, the water depth inside Pearl Harbor does not exceed 15 meters at most, which is consistent with the average water depth of Pearl Harbor in the "Oahu Fishery Resources Compendium" of 12 meters.

Zuo Zhong pretended to be eager to try, and made an appointment with the owner of the fishing tackle shop to set off early tomorrow morning to go fishing in a certain sea area. He spent money to buy a few sets of fishing gear and then left.

As the saying goes, poor students have too much stationery. Regardless of whether they can catch fish or not, equipment is absolutely indispensable.

After returning to the Sugar Trading Company, Zuo Zhong saw Ozawa still studying the newspaper, so he did not disturb him and went back to the room to modify the fishing gear.

He made a mark every 10 meters on the fishing line, replaced the lead bob with the heaviest one, and turned the fishing rod into a simple depth-finding hammer.

After dealing with these, Zuo Zhong sat on the bed and closed his eyes, silently reviewing his recent actions and looking for any omissions. He sat there for several hours.

When conducting intelligence activities on the territory of other countries, omissions mean exposure. If he is caught by ONI, the government will never recognize his identity, so he must be cautious.

Early the next morning.

There was no one on the streets, the dim light of the street lamps shone on the ground, and in the complete silence only the whistle of the distant military port floated in the air.

Zuo Zhong walked out of the shop carrying fishing gear. When he heard the sound, he raised his hand and looked at his watch. It was just 4 o'clock. He thought that this was a good way to determine the shift schedule of the US warship.

After thinking about it, he quickly walked to the civilian dock on Oahu Island. The fishing boat was about to set off. Fishing must look like fishing, otherwise it will not be hidden from other people's eyes.

When the time came to 8 o'clock in the morning, a rickety boat appeared on the sea several miles away from Oahu.

The bearded captain lay down in the captain's cabin to take a nap with his pipe in his mouth. Zuo Zhong took out his fishing rod and stood on the side of the ship and threw out the fishing line. The plumb bob and the fishhook sank to the bottom of the sea, and strings of bubbles emerged from the sea.

ten meters.

Twenty meters.

Thirty meters

Forty meters.

The reel rotated rapidly, and the fishing line on it continued to decrease. When the fourth mark disappeared under the water, the reel stopped running and sank to the bottom!

Zuo Zhong ignored the captain behind him, looked at the fishing line calmly, and roughly estimated the water depth, which was about 45 meters.

The information he stole from the library showed that there was a small trench below this place, and the measured depth in 1895 was 44.3 meters. Apparently the depth has not changed much in the past forty years.

If even the severely scoured trenches have not changed significantly, the same should be true for the submarine topography in Pearl Harbor.

Zuo Zhong stopped thinking and concentrated on catching fish. Unfortunately, he seemed to have bad luck. He didn't catch a fish until three days later, so he had to tell the captain to change positions with a dark face.

The fishing boat's engine started up again and headed in a certain direction.

Turning around and enjoying the sea breeze, the annoyed expression on Zuo Zhong's face disappeared instantly. He didn't even put out any bait just now, so naturally he couldn't catch any fish, so he had to take advantage of this opportunity to go a few more spots.

For a whole day, the fishing boats stayed in many waters near Oahu, and only slowly entered the harbor at sunset.

Zuo Zhong disembarked from the boat carrying a large bunch of sea fish and walked around the city in a arrogant manner, vividly interpreting the characteristic of a fisherman who gets lost as soon as he catches a fish.

When he returned to the store, Ozawa took the fish from his hand and was about to say something, but was interrupted by him shaking his head slightly. The hired clerk had not left yet, so it was inconvenient to say some words.

While Ozawa was waiting anxiously, the clerk finally left, and the two immediately came to the quiet room to exchange the information they had collected.

"Nan Jiajun, I compared the weather conditions in the past six months and have initially figured out the weather patterns of Oahu." Ozawagawa said in acknowledgment.

Zuo Zhong nodded slightly: "Well, I also re-measured the water depth and topography of 9 characteristic points. The results are very optimistic. I can report the weather and hydrological information of Pearl Harbor to Tokyo.

Just like last time, I will put the information in the dead mailbox and contact the intelligence officer at the consulate. In the future, we will only have one job on Oahu, and we will do our best to collect information about the Pacific Fleet. "

After making this decision, he suddenly felt something in his heart. This information is useless to the underground party now, but what about the future?
