Admiral Isoroku Yamamoto, commander of the Combined Fleet, was preparing to lead his division of tigers and wolves across the Pacific Ocean to attack the United States' Pearl Harbor on the Hawaiian island of Oahu, while in Washington, his delegation was still negotiating with the American representative in a pretending manner.

From Washington to Pearl Harbor, there seems to be no sign of war, and no one in the United States and China, across the ocean, seems to notice the slightest smell of war in the skies over the Pacific Ocean.

In fact, Li Ran and Bai Yu in Caijiazhou have already sensitively sensed the movements of the Yue army.

The work of the BFIPU has finally improved a little in recent times, because they have faintly sensed from the telegrams they have heard from the army that the devils are about to carry out a very important military operation in the near future.

From the large number of telegrams intercepted by the Chinese army, the words "east," "south," and "there is rain," which appeared frequently some time ago, have suddenly disappeared from the various telegrams of the Chinese army in the past few days, and have been replaced by words such as "vigilance" and "guard."

Based on their previous experience in deciphering and intercepting the telegrams of the Chinese army, Li Ran and his men felt from experience that the devils must have some conspiracy activities, so in order to cover up some of their own attempts, they deliberately concealed some of the methods of the past and made people feel that everything was normal.

As a result, the intelligence group did not dare to slack off for a moment, and they immediately reported the recently intercepted intelligence of the Chinese army and their own judgment to the theater command. After analyzing the matter, the Theater Commander's Department reported the unusual situation to the Supreme Military Council. The highest authorities forwarded their report to Chi Buzhou, the "black room of China".

As a matter of fact, Chi Buzhou and his colleagues have also noticed the abnormal actions of the Yue army, from the information about the "East" that appeared frequently in the Yue army some time ago, to the sudden disappearance in recent days. It was as if Hawaii, which had been so much of a concern for the past, had suddenly become worthless. This is not the practice of stubborn and cunning devils, there must be some conspiracy in it.

Chi Buzhou clearly remembers that not long ago, in October, the Ministry of Foreign Affairs suddenly ordered all embassies and consulates in the southwest and Pacific regions, including the Philippines, Vietnam, Thailand, Burma, Malaysia, Indonesia, Singapore, and other islands, to burn all but the simplest codebooks. At the same time, in the telegrams sent to various places, many hidden code names frequently appeared, such as: "West Wind Tight" means "tense relations with the United States", "Northern Sunny" means "ease of relations with the Soviet Union", "There is rain in the southeast" means "tight on the battlefield with China", and so on. After investigation, it was found that it meant "evacuating overseas Chinese" and that the political axe had requested that the overseas Chinese in the above-mentioned Southeast Asian countries be withdrawn. The Ministry of Foreign Affairs' telegram also clearly stipulates that these codebooks will be broadcast by radio broadcasters when necessary, and all embassies and consulates are required to listen to them at all times.

When Chi Buzhou and the others deciphered these secret telegrams, judging from the current situation, there were only two understandings. First, it is said that the army is about to advance southward, and it is imminent. Another bold speculation is that the military will enter a state of war with the United States.

When Chi Buzhou received the information from the Ninth War Zone, he felt that his opinion was more correct. However, it is not possible to report to the Supreme Council that the army is about to attack the United States on the basis of just a few telegrams that have been received. A clear message should be given to the highest authorities, and there must be conclusive evidence.

Chi Buzhou immediately demanded that the intelligence groups and personnel lurking in various localities, especially those in Shanghai, Guangzhou, Hong Kong, and other places, monitor the movements of the Chinese army 24 hours a day and report the abnormal movements of the Chinese army at any time.

At 6 a.m. on 26 November, Admiral Yamamoto Isoroku, commander of the Combined Fleet, issued an order demanding that the Nagumo Mobile Force immediately lift anchor and leave the port.

Led by three submarines, the mobile fleet of the Japanese army quietly sailed through the rough waters of the North Pacific Ocean, and sailed extremely secretly to the standby sea at 42°N latitude and 170°W longitude, where they would wait for the final order -- to attack.

At this time, in Washington, the capital of the United States, the negotiations between the United States and the United States were still going on in a pretend. It is said that the diplomats of the United States and the United States are still arguing about their own interests, and they are blushing and having thick necks.

At the same time, the Chinese military has dispatched a large number of warships and warplanes to carry out activities on its own territory, and has simulated a large-scale aircraft carrier formation and frequently conducted radio contacts, so as to give the United States the illusion that "its main fleet is still operating on its own territory."

The mobile fleet led by Vice Admiral Nagumo, who sailed in the vast Pacific Ocean, remained silent by radio, and they only received and did not transmit, and made a circuitous eastward route along the predetermined northbound route to avoid American patrol planes and merchant ships. The voyage of the huge fleet went unexpectedly smoothly, and the sky over the Pacific Ocean was covered with thick clouds, like a natural curtain covering the actions of the huge fleet. There are no rough waves on the surface of the sea, which are often set up in winter, and the speed of the voyage is unusually fast.

On December 2, just as Nagumo's mobile force had just crossed the east-west meridian line and entered the west-longitude sea north of Midway, Yamamoto sent a secret order to Nagumo with a new code: "Climb the new peak 1208", which meant to launch an attack on December 8 (December 7, Hawaii time) as originally planned. Nagumo immediately ordered the captains of the ships to turn off their lights and drive away, and conveyed the "Z Operation" operation to all officers and men. Be ready for battle at all times.

Yucheng, "China's Black Room". Chi Buzhou was already asleep on the marching bed and clothes in the cold office, and he was sleeping sweetly, snoring heavily from time to time.

Chi Buzhou was indeed too tired, and he hadn't had a full night's sleep for many days. Recently, he and his comrades-in-arms have been listening to the telegrams of the Japanese army day and night in accordance with the orders of their superiors, especially those telegrams related to Pearl Harbor in the United States, and they dare not leave a single telegram behind, and all the people in the intelligence room have been deciphering and analyzing these intercepted military telegrams day and night.

Suddenly, a hurried footstep came to the door:

"Director of the report, there is important information about the army."

Chi Buzhou jumped up from the bed excitedly, walked over, and asked very hurriedly:

"Is it intelligence about Pearl Harbor?"

The staff officer nodded and replied:

"Yes, Director."

Chi Buzhou hurriedly took the information handed over by the staff officer, sat down at the desk and carefully deciphered it. After deciphering it, he couldn't help but be overjoyed, jumped up excitedly, he took the telegram, circled around the room, and couldn't help laughing.

The second monk of the staff officer standing on the side was puzzled and asked suspiciously:

"Director, are you going to fight with the Yankees?"

"Yes, the devil who doesn't know whether he is alive or dead is about to fight with the United States. It's really 'heaven has a way you don't go.'" Hell has no door, you're here'. The devil is going to die. Hahaha-"

Chi Buzhou immediately sat down and hurriedly buried his head in writing down the information in his hand. The telegram is a specially classified telegram sent by the Ministry of Foreign Affairs to Nomura, the ambassador to the United States, and the content of the telegram is as follows:

"Nomura-kun: Please follow the following requirements of the base camp immediately:

1. Immediately burn all kinds of codebooks, leaving only one ordinary codebook, and burn all confidential documents at the same time.

2Inform the depositor concerned as far as possible to transfer the deposit to a neutral national bank.

3. The Imperial Axe decided to act in accordance with the decision of the Imperial Council.

Remember! Hope to follow suit! ”

Chi Buzhou combined with the military intelligence about Honolulu that he had deciphered earlier, and he deduced that the United States was about to go to war. He also made a detailed analysis of the situation of the war and came to the conclusion that the Chinese army was very likely to start a war against the United States on Sunday, and the location of the attack was probably Pearl Harbor, where the US Pacific Fleet on Hawaii Island was located.

Chi Buzhou personally wrote a report on the translated telegram combined with his own analysis, personally gave it to his boss Huo Shizi, and talked about his judgment in detail. Huo Shizi immediately put pen to paper and signed the opinion:

"Check the secret telegram sent by the ambassador to China to the consulates in China on the eve of August 13. At that time, the secret telegram ordered all consulates in China to immediately burn all kinds of cipher codes and telegram books, indicating that Kou had decided to launch an all-out war against China. Now, the Ministry of Foreign Affairs has similarly ordered the Embassy in the United States to immediately burn all kinds of cipher code books. Based on this, it can be judged that Ben is about to start a war against the United States. The time is about Zhouyue, that is, December 8th. ”

Huo Shizi then reported the situation to the Supreme Military Commission, and the highest Chinese authorities immediately notified the US envoy in Yucheng of this important urgent information, and through the envoy, asked him to immediately transmit the information to the US [***] authorities. It is a pity that the US authorities are still intoxicated with the negotiations with the delegation and do not pay any attention to the information sent by the Chinese authorities. Although the Chinese intelligence department sent information one after another and informed the Chinese army of the exact time of the attack, it still did not attract the attention of the US authorities.

On December 3, the same day that Chi Buzhou intercepted the telegram from the army, after receiving an order from Yamamoto 56, the mobile force of Nagumo, which was already on standby in the Pacific Ocean, immediately turned to the southeast and sailed.

Three days later, on December 6, the fleet supply tankers accompanying the army filled each warship and the aircraft on the aircraft carrier for the last time, and then turned around and left the formation to return home. The rest of the combat ships of the Mobile Fleet then turned to sail, increasing their speed to 24 knots, and traveled at high speed due south, soon approaching Pearl Harbor, the home port of the U.S. Pacific Fleet.

At dawn on December 8 (December 7, Hawaii time), the Nagumo Mobile Force arrived about 230 nautical miles north of Pearl Harbor on time. The aircraft carriers and other ships began to change course and head northward against the wind. Nagumo's flagship aircraft carrier, the Akagi, raised the bright red "Z" flag, and on the aircraft carrier, the plane's engines were activated, and the ground crew filled the plane with fuel and ammunition.

Outside Pearl Harbor, a miniature submarine lurking not far away raised its periscope.
