This dungeon has mushrooms growing on it.

Chapter 111, Question 110: The Glass Box?

Deep inside the tunnel, the reverberation of the chisel-like shells striking the earth never ceased in the darkness.

Several oxen and horses gathered up the pebbles on the ground and carried them away.

Because the tunnel is already several hundred meters long, it takes a lot of time to travel back and forth, so much so that the number of oxen and horses responsible for transporting the crushed stone now exceeds the number of excavators who are breaking rocks.

This area is far beyond the mining area of ​​the amethyst mine, and what is being dug out are all worthless stones, but the Puji are still doing their work under orders.

Because of the distance, Lin Jun had to also lay the mushroom mat inside.

To put it simply, the entire project generated no profit, and it's no exaggeration to say that it was a huge undertaking.

But if we can eventually uncover the underground city, then it will all be worth it!

clang--

Unlike ordinary mining sounds, it sounded like something exceptionally hard had been struck, and a creature trembled and collapsed to the ground—dead.

The enormous recoil force destroyed its internal hyphal structure, but it wasn't a major problem; death is not the end.

Since these digging creatures would occasionally injure themselves from the shock, Lin Jun applied [Mycelial Regeneration LV4] to them. Even if they were killed by the shock like this, as long as they were still intact, they could get up and get back to work after lying down for a while.

What Lin Jun was concerned about was that it was just ordinary rock formations in front of it, so why was there such a large backlash damage?
clang--

Just as Lin Jun was about to begin her research, the same sound rang out again, and the other one trembled and collapsed.

Lin Jun immediately ordered all the excavators to stop working and concentrate on the vicinity of the location where the two excavators had been killed, and began to carefully and meticulously excavate.

Before long, one of the "walls" was cleared out.

What are called "walls" are actually just rocks that can be seen everywhere in the tunnel. They don't look special at all, but they are just too flat!
It's not that it looks flat, but that it actually feels flat to the touch.

There isn't a single bump or unevenness; you can't even feel any friction when you stick the shell to it!
That’s outrageous!

If I had to describe it, it would be a very thin yet very strong transparent wall that separates the inside from the outside.

This "wall" is different from the air wall Lin Jun encountered on the stairs before. The air wall felt like a spring, a force that prevented you from moving forward.

This transparent wall is different; it's ridiculously hard.

To test the hardness of the transparent wall, Lin Jun even used mushroom cannons and self-destructing weapons, which even caused a small-scale collapse and required a long time to clear the rubble.

Even so, the transparent wall remained completely still.

Lin Jun even pulled Xiao Hei over and asked her to try to break the transparent wall.

One punch!
The transparent wall remained completely still!
On the contrary, the usually invincible Little Black was clutching its right paw and groaning in pain, making such a commotion that it almost caused another landslide.

After that, he hid in the mushroom house and ignored the mushrooms. Lin Jun could only rummage through the little treasure vault, but couldn't find any ordinary gems. She could only pick out a ring with +1 strength and give it to Xiao Hei to get his favorability back.

Since they couldn't dig horizontally anymore, Lin Jun had the Puji change direction and start digging upwards in a spiral.

This time, they didn't dig for long. Half a day later, with another thud, they reached the top!

This height is roughly where the fourth and fifth floors meet.

So... am I living in a big glass box?

Although she had expected that she wouldn't be able to dig out, finding herself living in a large glass box was still a rather strange feeling, reminding Lin Jun of the petri dish in her previous life...

Oath City, the capital of the United Kingdom.

In this royal city where land is incredibly valuable, there stands a magnificent yet sparsely populated building on the east side—the headquarters of the Relics Association. This building, over 300 years old, is constructed primarily of white granite, complemented by wooden decorative structures, and bears the many marks of time.

Under the midday sun, the entire building takes on a warm, honey-colored hue.

A magnificent carriage drawn by four black horses stopped in front of the gate, its prominent coat of arms representing the family to which it belonged.

Four mounted guards followed behind the carriage.

Eric handed the reins to the servant who approached him, got out of the carriage, and personally opened the carriage door to welcome the young lady sitting inside.

“Miss Inanna, Mr. Eric, welcome to our visit.”

A staff member from the Relics Association, who had been waiting at the door, greeted him with a smile. Inanna looked at the badge on his chest that represented his academic status, bowed slightly, and performed a noble greeting.

The "Hero's Summoning" was long over, but the demons, having suffered a loss, never stopped their retaliatory actions, and Inanna was forced to stay at home for several months.

However, she never forgot that she still needed to help Lin Jun find information about the underground city.

This time, after much pleading and cajoling, she finally got her father's permission to come to the Relics Association with Eric.

Eric, who was standing nearby, naturally guessed that Inanna's purpose in coming here was probably related to the letter from last time, and he had also sent someone to inquire about the man named Dylan.

Although there are suspicious points, such as suddenly receiving a large sum of money to buy anti-life drugs.

But logically, he shouldn't have had any interaction with the young lady.

Eric concluded that he was probably just a middleman, but he couldn't find out anything about the people behind him.

Recently, even Dylan has disappeared, so the investigation has to be temporarily suspended.

Guided by the scholar, Inanna walked through the hall and along the corridor for nearly ten minutes until she arrived at a place that resembled a library.

"Level 2 access permission".

The scholar took out a document bearing the Duke of Alama's seal and handed it to the old man guarding the door.

The old man glanced at the document, signed it, and let Inanna in, while Eric remained where he was. In principle, he wasn't qualified to enter—level two access privileges were granted to Inanna by the Duke of Alama.

It could even be said that he wouldn't have been able to enter the headquarters of the Relics Association if he hadn't been accompanying Inanna.

"Miss Inanna, you requested to access information related to the dungeon, right?" the scholar walking in front asked gently.

Although he acted like a proper host, Inanna dared not be negligent, knowing that her magic teacher was only a bachelor.

"Yes."

The scholar led Inanna through three compartments to a row of bookshelves.

"This room contains information about the underground city, covering a wide range of topics. You can choose what to look at."

Because this is classified as "Secret," you cannot take it out of the house. Please read it here.

Inanna nodded first, then looked at the entire row of bookshelves and was a little stunned; she hadn't expected there to be so many!
She looked at the scholar for help.

Seeing her expression, the scholar finally couldn't help but chuckle. After thinking for a moment, he stepped forward and said, "I personally suggest you start with this book."

As he spoke, he pulled a book from the bookshelf: "The Structure of Underground Cities Beyond the Naked Eye."
