Life is very peaceful, and the training every day is only one hour later. The main reason is that there is not enough space for training, so our squadron colleagues can only train outside in batches. Although the lighting here is very good, I haven't seen the sun for four days. This place makes me feel inexplicably depressed and fearful..."

"May 9, 1943, the weather is unclear. Yesterday's events were a bit unexpected. First, in the morning, Mr. Ohno from the third team accidentally fired his gun during training, and the bullet penetrated Mr. Inoue's left arm. Fortunately, it didn't hit Mr. Inoue's bones. I cleaned and sutured Mr. Inoue's wound. After a few days of rest, Mr. Inoue will become a lively guy again. As for Mr. Ohno, he was scolded by Mr. Nakamura and locked up. May the great god protect Mr. Ohno.

When it was almost time for lunch, Ito-kun, who went into the water to check the underwater gate of the base, had an oxygen tube leak. Fortunately, Ito-kun was a very good swimmer and swam up on his own. After I checked him, I made sure that there was nothing wrong with his body.

In the afternoon, three officers came to the base. They were said to be from Guam. From now on, the three of them will live here with us.

Just as I was about to write down the mess that had happened today, an alarm that had never sounded before sounded in the base. At first I thought it was the Americans attacking, and I was a little panicked, but then I remembered that this was not a combat alarm, but the alarm when the base's underwater gate was about to open.

It turns out that the underwater gate of the base will be opened tonight and ships from outside will come in. No wonder Ito-kun has to go into the water to check the gate at noon this afternoon.

God bless you, the submarine that entered the base tonight was actually a patrol submarine of the first class, with the hull number I-2. I know this submarine, it was built by the Imperial Navy with submarine technology exchanged from the Germans, it was built and launched by Kawasaki Heavy Industries Kobe Shipyard in the first year of the Showa era, and there are a total of 60 crew members on board.

Seeing the boxes of gold foil, Chinese silver dollars, platinum, and jewelry being carried up from the submarine, I finally knew what exactly this base was going to store. Long live the empire! With so much treasure, why worry about the empire not being able to hold on? So, even though all of us worked all night and were almost exhausted, we were all very excited..."

When Yang Jing saw this, he compared the records in the diary with the missing warehouse management ledger found in the base.

This military doctor named Jiro Noda set out with the troops on April 23, 1943, and arrived here after spending ten days at sea. Then his diary recorded some trivial things that happened just after arriving at the base until May 8, 1943.

At this time, a first-class patrol submarine with the hull number I-2 arrived at the base, and the warehouse base secretly built by Onishi Takijiro also welcomed its first batch of storage materials.

The first year of the Showa era written in Noda Jiro's diary was 1926, the year when Emperor Hirohito ascended the throne.

As for the valuables moved from the submarine, although Jiro Noda did not record them in detail in his diary, the time happened to correspond with the warehouse manager's account book.

That is, the secret base located on the West Island of the Mauer Islands was officially put into use on May 8, 1943.

However, this military doctor named Jiro Noda was obviously not a very diligent person. He did not write in his diary every day, but rather intermittently. It seemed that he would only write a few words when something different happened.

But this is no wonder. This guy, like the Japanese troops stationed here, probably hardly sees the sun once a week. Apart from limited training, Cheng has almost nothing to do in the base. So what is there to record?

This is indeed the case. In the following diaries, there is almost no interesting content in Noda Jiro's diary. It is all just some random things he wrote out of boredom.

However, Yang Jing did find some valuable information from these two diaries. For example, every time a submarine came in from outside, Noda Jiro would record it. After all, every time a submarine entered the base, and the weekly "outing" to see the sun, these two things were undoubtedly the most grand festival for these soldiers who were so idle that they wanted to count their comrades' hair and pick lice.

Going out for a walk was a luxury, after all, the concealment of the base was the most critical, and at that stage, American reconnaissance planes would visit the Mariana Islands and even the Kasahara Islands further north from time to time. Therefore, going out for a walk became an extremely luxurious thing for the Japanese troops stationed here.

And every time a submarine came in, Noda Jiro and his men could have a good exchange with the submarine soldiers who were also holding their breath. Even if it was just a conversation, it was a very pleasant thing for these soldiers who had never seen the sun...
