The letter has a clear record, saying that the place where Liu Dianchen eavesdropped on the meeting of senior Japanese officials was Fengping City in Zhaoyun Province. Fengping City was not only the capital of Zhaoyun Province, but also one of the main rights centers of the puppet Manchukuo regime at that time.

Since the Japanese senior Japanese military officials held a secret meeting here, it means that the treasure was most likely hidden in the mountainous area near Fengping City. When the Military Control Commission investigated, it also focused on Fengping as the center and regarded this area as a key area.

However, if you look at the map, you will find a helpless fact. Fengping City is surrounded by mountains on all sides, with deep mountains and forests all in the southeast, west and north. They are all counted together, at least thousands of square kilometers.

No wonder, the Japanese devils chose this place to build a fortress and buried treasures. It was really difficult to find it!

In the notebook, Tao Xiang’s original search for the treasure is recorded. Tao Xiang’s investigation of the treasure is divided into three directions:

First, we mainly focus on collecting historical clues.

This is very important. Over the years, Tao Xiang has consulted countless local historical materials and visited countless villagers, and has been tirelessly inquiring about the treasure.

Tao Xiang's starting point is very clear. He believes that if such a secret fortress really exists, then its construction process will inevitably be similar to that of Shengshan Fortress. The Japanese devils will definitely use Chinese migrant workers from other places to build it. After the construction is completed, they will inevitably kill people to silence them and create a massacre tragedy.

Therefore, Tao Xiang tried to find such a mass pit to judge the general location of the secret fortress.

In addition, he also believed that if the Japanese devils wanted to keep the secret, they might commit even more outrageous behavior, that is, slaughtering the villages near the fortress! They had to level up the villages near the fortress without leaving any living occupants so that the fortress could be avoided by local people!

Therefore, if a village similar to that destroyed by the Japanese army could be found, the location of the fortress might be determined.

The reason Tao Xiang took Cui Lizhu to settle down in the Golden City was because he had received news that he had discovered many ruins of abandoned villages in the mountainous areas outside the Golden City.

However, after careful investigation, he regretted to find that those villages were not caused by the Japanese, but were caused by environmental deterioration.

Tao Xiang’s second direction is a field investigation.

According to the records in Liu Dianchen's letter, he went to search for clues on the spot, trying to find clues about the activities of the Japanese army.

For this reason, he purchased valuable professional equipment and also learned a lot of professional knowledge. But the scope was too large, and this method was tantamount to finding a needle in a haystack, and he had to give up in the end.

Just behind Tao Xiang's notebook, there are many schematic diagrams of mountain areas, most of which are marked with a big "X", indicating that the place has been excluded by Tao Xiang.

As for the third direction, that is the relevant personnel!

Tao Xiang also believed that it was impossible to determine the existence of the treasure with just a note from Liu Dianchen. Therefore, he spent a lot of time and used his profession to conduct a detailed investigation of all personnel and events related to the treasure.

Over the years, he did find out a lot of intriguing news. For example, after the Kuomintang was defeated and fled, they still did not give up on the treasure. They sent spies to search for it many times. Not only did they find nothing, but they also accidentally leaked the secret of Liu Dianchen's letter.

The one that Tao Xiang got accidentally was one of the lost copies.

Tao Xiang suspected that the interrogation note he received should be only a small part of the entire note, and only one rough process could be learned, and more detailed information should be retained in the world.

Secondly, such an amazing wealth may be located in the Northeast. At the national level, it is impossible to stand by and watch.

Through Tao Xiang's investigation, he can confirm that since the founding of the People's Republic of my country, China has organized many searches for treasures. The government has sent many famous experts and scholars, and cooperated with advanced scientific exploration technology. It has searched many times, but in the end it was incomplete.

In addition, Tao Xiang also received two news from unknown sources, saying that the Russians and the Japanese were also looking for the whereabouts of this batch of treasures.

Regarding these two news, Tao Xiang felt that the Russians were a little more reliable. After all, they were the victims, and it was reasonable to still be thinking about gold.

Although gold may be hidden in China, once found, they still have the hope of recovering it through legal means. More importantly, if gold can be found in the secret fortress of the Japanese army, they can prove the fact that the Japanese snatched gold, and use legal means to formally claim compensation from the Japanese government!

As for what the Japanese were looking for, Tao Xiang felt it was purely nonsense. Firstly, the treasure was buried by the little Japanese. Of course, they knew the location of the treasure, so could they still use it to find it? Secondly, if they came to China to find the treasure, it would be extremely stupid. Even if they found such a huge treasure, what could they do? In the end, they could only make wedding dresses for others, which would not be worth the loss.

"Tsk tsk..." Cui Lizhu looked at Tao Xiang's notes and smacked her lips, gradually regaining her rationality, "Boss, this matter is really hard to do! Since our country has sent so many experts but has not found it, then we..."

"Right?" Zhao Yu nodded proudly, "I said, it is impossible for our country to stand by for such a big thing! Let me tell you again, maybe those treasures have been taken into account by our country! It's just that it has not been announced to the public! Because of the gold dispute, it is reasonable not to announce it to the public!"

"Oh..." Cui Lizhu patted Zhao Yu's shoulder with her hands, "Boss, your level is not low anymore. Otherwise, you can ask someone? If there is really no treasure, let's not do useless work, right?"

"Just kidding!" Zhao Yu shook his head, "I'm a big furious level? Such a big shocking treasure, let me say that even the biggest leader of the Criminal Department has no authority to know!"

"That's it...then..." Cui Lizhu asked again, "Just ask who has the right to know?"

"What are you doing?" Zhao Yu glared, "You don't want to do your old job again, are you?"

"Tsk tsk..." Cui Lizhu was depressed, "What should we do? If we don't know anything, we go to find the treasure. Isn't that equivalent to being blind? It's meaningless!"

"I don't know this yet? Why don't we do this..." As he said that, Zhao Yu opened the notebook and pointed to many names of people behind the notebook and said, "This is the list of people left by your father. The people on the list should be people who are related to the treasure! Look, some of the names at the top of the list were all marked X by your father, and only the few behind are left!"

"Oh..." Cui Lizhu thought, "If you call number X, is it that my dad has investigated it? Then... you didn't call number X..."

"Look, there are five people here who have not played number X," Zhao Yu pointed to the list and said, "Either, your dad has not investigated them yet; or, these five people are closely related to the treasure and know more hidden information. So..."
Chapter completed!
