Lying on the wall, Orson reached out and knocked on the wall while listening.

The sound of "Dong Dong" reverberated in the dark.

"Fortunately, the wall is not very thick, about one to three meters. With our existing tools, we should be able to chisel it in three hours. Everyone, let's start."

The team led by Orson is an archaeological team, and the tools used for digging are necessary.

It's a kind of small engineering shovel. It's very small, but it has complete functions. It can dig soil or stone, but the efficiency is not very high.

Everyone stepped back, including Tanya. People with engineering shovels came forward one after another and began to chisel the wall.

"Dong Dong" percussion sound immediately reverberated in the dark, each shovel down, the whole tomb seems to be shaking, which shows that the space is in an unstable state.

Think about it. Although the tomb is a whole, the ground above collapses, and all the weight is on the top of the tomb. Of course, this will exert certain pressure on the structure of the tomb.

Although some people are worried that the tomb will collapse due to the wall cutting operation, they have no choice. If they stay here, they will also die. They may be able to survive safely for a few days, but if they can't find a way out, they will die sooner or later.

Although there is air and comfortable temperature, no one will feel at ease in this narrow space.

In the light of the helmets of the soldiers, with the help of the still bright light, Orson's team is working hard.

Whether there is an exit behind the wall that people expect is still unknown. In the dark, three hours is not a short time.

Unconsciously, the retreating Orson came to Tanya's side.

In the dark, Tanya's voice rang and said, "is it worth it for a key? In the Renaissance era, antiques with a long history have the value of collection, some of which are called "Kebao" relics of ancient times, even valuable. But in this era, antiques have no value, it is not more precious than a grain of grain. "

This sentence is of course to Orson, but to Tanya this question, Orson very indifferent answer.

He replied: "the general is right. Whether it is gold or antiques, they are worthless in this era and will not bring visible benefits. But from these antiques, we can know what kind of era human beings were in thousands of years ago. It may not be important for us to pursue the past, but if we know the origin of human beings, Then we can have a better understanding of our own existence. "

"The history of human beings is clearly documented more than 2000 years ago. Most people have always believed that the human race evolved from the ancient ape, but I don't think so. I always think that the origin of human beings is more mysterious than everyone's imagination, general! Do you believe that we evolved from hominids? "

To this question, Tanya's answer is very vague.

"What if you get the real answer? Maybe it scares you and scares you from facing it. "

Naturally, Tanya is not interested in the origin of human beings. However, after getting along with her master for a long time, Tanya knows more or less about some things.

In the vast universe, the earth is not the only place where human beings originated. In Al, the blue star in the main population, and even the "edras" in the magic world also exist human beings.

As a human being, Tanya was very surprised that there was "Earth" on the other side of the universe, the planet where human beings live, because her previous cognition had been completely overturned. However, with the expansion of her vision, it was not difficult to think of and guess some things after she became Shiji.

Where is the origin of human beings?

Who knows?

Perhaps in "Al", or in the blue star, or in some unknown planet, only one thing is clear. The reason why the human race can spread all over the universe can only show that in a long time, human civilization is not limited to the "parent star".

To Tanya's vague answer, Orson sighed and said: "no matter what the real answer is, no matter whether it can make me feel fear, my biggest goal in my life is to find the origin of human beings. If I can really get the real answer, it's what I dream of. I won't be afraid, I will just accept it calmly."

Maybe this is the only wish in his heart as a mortal.

Wish is good, no matter what kind of wish, should not be denied.

Unknowingly, in the waiting, the passage of time bit by bit.

Knowing that there was a way out on the other side of the wall, Orson's companions all worked very hard, throwing an engineer shovel to dig through the wall bit by bit.

"Yes, yes!"

I do not know how long, with a cry of joy, the wall was finally dug through.

Although only one cut was made, it confirmed that there was a passage behind the wall.

Seeing the hope of leaving, they all worked harder and knocked hard with the shovel in their hands. In the sound of "Dong Dong", the wall was cut open enough for one person to pass through.

"What's in it?"

Although the passage was opened, the back of the wall was dark, which made people feel scared subconsciously.

A soldier stepped forward and used the beam from his helmet to shine into the space on the other side of the wall.

This time, people finally know what is on the other side of the wall.

Looking at the dim and narrow space opposite the wall, Orson said: "it's the sewer. We are very lucky. Although the ground nearby collapsed, the sewer has been well preserved. This is our luck."

To Orson's words, Glen emphasized: "it's just luck at this time. At least we can leave this ghost place. OK, let's go. The earlier we leave here, we will have more time to help our friends buried in the ruins. There is not much time left for them."

Although we say that, we all know that the survival rate of those companions buried in the ruins will not be too high. It is not easy to just say that they want to leave here, not to mention the difficulties in rescue.

At Glen's call, the people in the tomb began to act.

The first one to leave the tomb is Tanya's subordinate. The light in the team comes from the light beam on the soldier's helmet. There must be a soldier in front to explore the way.

The process of leaving the tomb was quite smooth. After all the people entered the sewer, they began to grope forward.

Compared with the tomb, the sewer is much narrower. It is a cylinder shape, with a height of no more than three meters. There is a thick layer of water on the ground, with some unknown vegetation floating on it.

It's like a kind of algae, very dense, stepping on it is like stepping on a soft carpet.

If it wasn't for the "Hua Hua" sound of water and the shoes that were invaded by water, that kind of touch would really be the same as the carpet.

Perhaps it is because of the cylindrical structure of the sewer that the sewer was not destroyed in the collapse.
