"Let's go in first." Professor Zhuo lowered his head and walked inside, they had been outside all night, and they were already too tired to die.

We went round the main room, and there was nothing in it, along with the fire that had been lit last night, as if nothing had happened.

He went in and walked around, and saw the tent embroidered with the Japanese military emblem inside, as well as the table made by the marching battle at zero hour. I was probably so tired last night that I didn't notice a lot of details in the house.

"What did you say was going on here?" Men Yuebin asked Qin Ge again.

"The base of the Yankees." Qin Ge said it again, in fact, everything that could be seen in front of him was obvious, but Menyue Bin didn't believe it.

Sure enough, Menyue Bin said that it was strange, the Sichuan army was notoriously fierce during the Anti-Japanese War, and the Japanese had no chance to get in.

"Xiaomen, this is what you don't understand, although the Japanese army did not enter at the beginning, there were also small forces that infiltrated and planned to do intelligence work. In September 1942, the Japanese army issued the "No. 5 Operational Preparation Guidelines", planning to eliminate the national power through the Xi'an operation and the Sichuan operation. Professor Zhuo walked up to the table and lifted the huge tablecloth, and a strategic offensive map appeared in front of our eyes.

"How could little Japan come to this meeting place and build a strategic base? Crazy? ”

"This is no ordinary strategic military base, and there may be some secrets of Little Japan involved here."

"What did you find again?"

"Three feathers. It is the symbol of Japan's Showa warlord group, a top-secret organization formed by Japan during World War II. It is said that there are 11 people in this organization, and all 11 of them are important figures in Japanese military circles. The things they studied were all completely secret in Japan, and they didn't think this camp would be theirs. Professor Zhuo pointed to an icon on the map.

It was a pattern of three birds leaning together, a seagull, a crow, and an unknown winged monster.

"Tetsuyama Forever, Ninji Okamura, Toshiro Ohata." Professor Zhuo said.

"Absolute confidential?" I suddenly thought of the diary that Hu Yinman now had in his hand, and what was recorded in it seemed to be a secret of the Japanese army. "Can you read Japanese?"

"I learned a little from my dad, who worked as a telegraph codebreaker in the army in the early years, so I know a few things about the organization of the Three Feathers, but I really didn't expect to see it here."

"Then can you see what the documents here are written, I have seen them, and the documents here seem to be new and very comprehensive." We walked in with Professor Zhuo.

Soon, Professor Zhuo took a cursory look at all the documents here, the map in the base is the trend map of the mountains and rivers in Sichuan, the mark on it is the route that the Japanese army was preparing to attack that year, and the things in the file cabinet record the description of this place.

The Yi people believe that the depths of the Shimen Pass in Heizhugou are the birthplace of their ancestors, and it is a place where the living cannot step in, unless after the person dies, because they feel that after the death of the person, the soul must return to the birthplace of the ancestors, that is, to the place of the "six ancestral branches".

The branch of the six ancestors is the world of the dead, in this world, there is no concept of time and space, how to say, it is what we ordinary people call the underworld.

"So this forest is the underworld?" I suddenly thought of the climber who had been repeated yesterday, and the child with black pupils, who might have been the travelers who had stumbled and died in the black bamboo ditch.

"It's not scientific, but it's true." Professor Zhuo said, "Last night, what we encountered in the forest was even stranger than what you encountered. ”

"What's there?"

"Mountain ghosts and dead people without faces." Chen Xiaofei whispered.

Professor Zhuo went on to say that after extensive investigation, the Japanese army found that the dead here would only appear when the sun was foggy and sun. So they think it's all a mirage.

"Mirage?"

"It's a mirage, a kind of refraction of light is a projection, and the projection of those who die comes from the underworld."

And the place that is refracted seems to be here. The Japanese believe that there is a mysterious force in this place, and it is this force that guards the ancestral land of the Yi people, so that the ancestors are not infected.

However, soon Gangmura Ninji knew about this place, and he didn't know that for the purpose of research, he entered here with three feather blacks, and after a period of exploration, he found that all the fog here came from the ground, so they began to dig underneath, and soon dug a cave, and there were human voices in the cave, and some things that did not belong to this world, and the Japanese were frightened, so they did not dig any further.

Closing the last file, Professor Zhuo summed up all the above information about the Japanese army in this place, of course, in addition to these, there are some military secrets, and letters, these things have no role in this peaceful era, and the war is over. But looking back, I really think that Japan's rhetoric is quite ridiculous.

I shook my head, "No, there's more to this place than that. ”

"It's true that these documents mention that the three feathers are looking for something that can change the tide of the battle, but they are not recorded in detail."

"Could it be that the level of the file is not enough?" I asked.

"It's possible." Professor Zhuo nodded.

"Well, there's a dark compartment here." At this time, Lu Zhongren found a document bag in the wooden compartment behind the filing cabinet, and he took it out and handed it to us.

Professor Zhuo took the document bag, bypassed the sealing rope, and carefully uncovered the fire glue paint, which was a letter with a pentagram printed on it, and an English "ZERO" on it.

"Document 0?" Professor Zhuo's hands trembled: "It is said that this is the highest level confidential document of the Japanese army, in the entire War of Resistance against Japan, we have never seen this kind of document, and we have only heard of it, how can there be a copy here?" ”

Soon Professor Zhuo sat down and read the entire document from beginning to end over and over again, four times, and Menyue Bin became impatient: "Alas, I said what about you? Still waiting for him to serialize it for you? What is written on it? ”

Professor Zhuo stretched out two fingers, trembled and clamped his glasses, took them off, wiped them with a sigh and put them back on.

"It's a document that can disprove most of the existing scientific facts, I don't know how to describe it, I don't know what to say, but I do know that it's a product of a collection of materials stolen from Japan from the Germans."

My heart jumped, and by the way, it was supposed to be a story about why Japan was looking for a tree that led to the sky.

"Okay." Then Professor Zhuo put down the letter and said to us slowly: "It all started with the Soviet battlefield in 1941. ”
