The exclamation from the board interrupted Zhou Ao's question.

Because he had just professionally twisted a handful of dirt, which was of different colors.

In addition to the yellow soil formed by the humus of the jungle, there is also a pronounced black-brown soil, which is called "gray soil" in the row.

If the modeling in the game follows the laws of reality, this pinch of dirt can explain so much.

It represents traces of human activity, ash, humus usually formed by human production of household waste, and there is a possibility, which is well known to the board.

That is "burning earth".

Soil and other materials are incinerated to form burnt clumps, and after a long time, under the influence of external forces, they will become a handful of dust in their hands.

His graduate thesis was related to the "digging party" that once swept Europe.

The so-called excavators are actually lovers of excavating war relics.

There have been many major battles on European soil, and these diggers often dig up the remnants of these battles.

However, due to safety and cultural relics protection reasons, European countries launched official protective excavations, which made the popular digging party disappear.

Due to fate, Banmian also went to Europe to visit several well-known diggers when he was a graduate student.

I had an in-depth communication with them.

Especially in the excavation of war relics, they mentioned "distinguishing all kinds of burned soil", which has some reference significance for archaeologists who always shovel in Luoyang for field excavations.

Later, Banmian graduated and went to work in the research institute to assist the local police in excavating many war relics in China.

So when Banmian was young, he always said that he was half a "digging party".

I didn't do this work for many years.

Now when I see this dirt, all the memories come flooding back.

His first reaction was to exclaim:

"it!"

"Damn, what's wrong with you, brother, scare me."

Zhou Ao was frightened by the exclamation of the board, and the movement of drilling wood in his hand stopped.

"There are traces of human activity here, and there may be ruins buried underneath."

Several more samples were found on the board, and all the evidence pointed to a war that had taken place here.

At this time, the board seems to have returned to his youth, every time he finds a land with excavation value, he will be so excited that he can't sleep, and when he gets together, the tools are complete, and the vitality of starting work immediately, he actually feels it again in the game.

Zhou Ao felt that the old brother in front of him had a sudden change in temperament.

Although Xiao Hei has no nose and no eyes, the confidence in his tone that naturally exudes from the inside out cannot be faked.

By looking at the soil, you can see the remains of the buyer below, which is not something that ordinary people can do.

Through the dozens of related novels he has read, Zhou Ao has formed a preliminary judgment in his heart about the real-life career of the old man in his heart, relying on his excellent brain replenishment ability.

Hearing what the elder brother said, Zhou Ao's heart also became excited.

In the future, when you go out and brag with others, you can talk about your experience of fighting in the game.

"Then, big guy, shall we dig?"

"I don't have a tool, but it's in the game anyway, so dig it!"

The surface of the board was selected in a loose place, and shovel after shovel dug up the soil on the ground.

Zhou Ao saw the professional technique of the old brother, and the excavation efficiency was extremely high.

I was more sure of my own judgment.

I also found a place to dig the soil by hand.

Xiao Hei's physical fitness is not strong, and many people in the game have been digging for two days, and the current digging efficiency is not much worse than that of an excavator.

didn't dig deeper, Zhou Ao felt like he had a hard object.

"It's shipped, big guy!"

"What is it?"

When Banmian heard this, he hurriedly ran over to take a look.

"I don't know, it seems to be a big guy, I'll dig out all the soil around here and take a look."

Zhou Ao was happy, and the whole person threw himself into the ground, carefully pulling the soil around the thing.

"It's metal."

When I took a closer look, I immediately saw some clues.

Habitually scraped the dirt off the thing with his own multi-purpose tools.

Black oxide layer.

However, the oxidation reaction is not obvious, and this layer of rust will be scraped off.

It is speculated that it has not been buried for a long time, or that the metal has a good anti-rust effect.

The board was tapped lightly again.

"Bell, bell."

Muffled voice.

It is hollow, but the metal layer is thick.

"Big guy, what do you think this is?"

"It's hard to say, let's dig deeper."

The deck uses tools to quickly clean up the dirt around the metal.

This proficiency made Zhou Ao staggered.

It won't be a repeat offender, do you want to quit the game now and call the police?

Maybe it can even involve a big case.

The two of them worked together, and soon cleared a large area around the metal.

But even so, they still didn't understand what was in front of them.

There is a metal pillar half a person high, and the thickness is about the same as the width of the female character that Zhou Ao pinched out.

Ban Mian was even more curious, so he took a small shovel and kept scraping there.

"We're not going to find out what's going on in the next edition, are we?"

Zhou Ao speculated:

"After all, if I were making games, I wouldn't have thought that anyone would find this thing this way."

Banmian didn't answer him, but he still focused on scraping the soil.

Soon, he discovered that one side of the pillar was numb, with a lot of dense lines like fingerprints.

The other side is smooth, but a large indentated sign is found at the top.

Because it was rusty, I couldn't see what was engraved on it.

I don't have the tools on hand, so I can only do some work that may damage the details.

Slowly scraping off the rust, a sign they'd ever seen appeared on the metal pillar.

This emblem resembles a crown.

They had seen in the Alpha Mobile Fortress, and many of the doors in the functional area had such carvings or spray paints, especially on the gate in the central area, the carved patterns like circuits converged into such a huge pattern.

At first, I thought it was a sign of the fortress, so I didn't care.

Now it seems that there is another mystery.

"Boss, we may have touched on the game's backstory."

"Possibly, may I ask 147?"

In fact, strictly speaking, they have not been exposed to the real plot until now, but they just say that they are a sleeping warrior who wakes up in order to achieve some kind of mission.

What the background of this world is, no player has been able to guess from the clues on the fortress.

I can only guess that it's probably the background of the sci-fi genre, after all, such a huge mobile fortress is in front of you.

"147, what does this pattern represent?"

No response.

But soon, a tall shadow appeared in front of them.

The nearly three-meter-tall giant made it impossible for two people to look up.

This ...... that suddenly appeared The NPC, they've seen, is the commander who sent them a video email when they first activated the communication function.

"This is the national emblem of the Rhine Empire!"

Qiu Wen said in a deep voice.
