The seismic survey lasted for about five months. After all the collected data was compiled, there was indeed a discovery—but that discovery left everyone dumbfounded.

The survey showed that, at a depth of 1,200 meters beneath this area, there was an abnormal reflection of seismic waves. On the film, it appeared as a very prominent, irregularly shaped white shadow, resembling a cross. The precision was astonishing: forty-nine meters long, thirty-four meters wide, as if a block of metal was embedded in the earth’s crust 1,200 meters underground.

When we saw this footage, everyone started talking at once, finding it unbelievable. However, when the technicians in the film enlarged that tiny cross-shaped spot, the room immediately fell silent again.

It turned out that, after being magnified two hundred times, the cross-shaped white shadow clearly revealed a geometric outline. Everyone instantly recognized what it was—it was actually an airplane!

It took me a long time to process this. In other words, at the site the Japanese had surveyed back then, we discovered that, embedded in the geological crust 1,200 meters underground, there was actually a bomber!

4. “Shinzan” (“Deep Mountain”)

At this point, many people will think I’m making things up.

Indeed, this is truly an inconceivable matter. We all received a very pragmatic education, and that era prided itself on materialism. Many inexplicable things would be forcibly explained away with far-fetched reasons, so I had no experience accepting things like this. My first reaction at the time was also to think it was nonsense, pure fantasy.

But looking back later, it’s actually not that hard to explain. Because, in fact, if something has become a reality, then there must be a way for it to have happened.

Let me add a note here: this is where the “Zero Tape” ended. At the time, I was so shocked that I didn’t even notice how abrupt the ending was. Only later did I learn that this reel of zero tape actually had much more content after this point. Of course, by the time I found out about these things, the hidden content had long since lost its meaning. When I first learned the reason for hiding this content, I didn’t understand it at all. It wasn’t until I led a team myself that I finally understood what those leaders were thinking back then. Maturity always comes at a price. Looking back on my life, almost every time I matured, it was accompanied by sacrifice and lies—truly helpless.

Afterward, Colonel had some interactive discussions with us. Many people thought it might be a coincidence, that perhaps there was a lump of pyrite or pure iron formed during some ancient geological catastrophe, and it just happened to take that shape. But Colonel told us: based on careful analysis of the outline, it should be a Japanese “Shinzan”—a very rare heavy bomber, which the Japanese usually used as a transport plane, put into service at the end of World War II, with very few ever made. So the likelihood of coincidence was extremely low.

Since it wasn’t a coincidence, the next step was to make inferences based on the facts. Colonel explained to us the conclusions reached by the survey team and many experts at the time, after much discussion. Their reasoning was as follows:

First, the premise: they had indeed discovered a Japanese bomber deeply buried 1,200 meters underground. They did not deny the possibility of its existence, but instead considered how it could have gotten there.

There was only one possible explanation. According to materialism, if the plane didn’t appear there through some absurd spatial distortion, then it must have been put there by the Japanese themselves.

Likewise, to reach that depth, there must have been a passage. And it was obviously impossible to move the entire plane down there in one piece, so it must have been transported in parts.

So the situation could be hypothesized very clearly:

Back then, the Japanese, by some unknown means, dug or found a passage leading deep underground here. Then, they disassembled a “Shinzan” and transported it down in pieces, and at the end of the passage, 1,200 meters underground, they reassembled the “Shinzan.”

As far-fetched as this theory sounds, it was the only reasonable possibility they could come up with.

To verify this hypothesis, there were two prerequisites: first, to find the passage leading underground; second, to find traces of large amounts of equipment having been brought here.

Colonel said that they had found traces of large quantities of antifreeze oil nearby, which should count as proof of the second point. Now, the engineers here were conducting a wide search, hoping to find the first prerequisite. Once the passage was found, a team would be organized to go down and see what was really below.

This was the reason we had come here.

The meeting ended at this point. Colonel repeated the confidentiality regulations, then let us move about freely. As soon as he left, the whole tent erupted, almost in an uproar. We weren’t afraid—to be honest, when it came to tunnel exploration, all of us had experience, and no one was scared. We were excited. In the midst of monotonous survey work, something like this was undeniably fascinating.
