"Guys, let's talk about how you think this cave came to be?" asked the kingdom's chief scholar as he asked the surrounding attendees.

"I don't think it's the caves that the invaders dug up. The chief army general of the kingdom held his chin with his hand and began to speculate, "Even if they have the ability to make very powerful weapons, then it is impossible for them to dig such a long cave, it is definitely impossible! To dig such a cave equipment, it is dozens of times more powerful than those powerful weapons!"

"I don't think it's a cave they dug either!" said the kingdom's chief admiral next to him, "it must have been a natural formation...... But...... It's a little strange why we ...... before we if these caves existed."

"Yes, that's what I thought, and that's a bit weird. The chief treasurer of the kingdom on one side said, "If this cave existed before, why didn't any of our ancestors follow this cave to explore the situation outside these mountains?"

"That's right, in general, most of them are in the direction!" the Chief Scholar of the Kingdom affirmed to several people.

The few people who spoke just now looked at each other, still not quite sure what was going on.

"So, how did that cave come to be?" asked King Malatinius curiously.

Then, the chief scholar of the kingdom said to Maletinius: "The recent research findings are indeed shocking, and may be beyond your imagination!"

"Oh?!......" King Maletinius was more interested.

The conference hall was silent.

"Those caves are very likely to have been dug by man!" the Chief Scholar of the Kingdom said in a serious tone, "But not those strange enemies this time, nor the people of our land!"

"By the way, how did you find out...... Did you find out that this was a cave dug by man?" asked King Malatinius, taking a sip of water, and then asked with some confusion.

"The result of extrapolating from those ancient texts, Your Majesty. At this point, the chief scholar of the kingdom looked at King Maletinius, and then said, "Yes, it is so. ”

The Chief Scholar of the Kingdom told everyone that he had begun to study the Cave of the Invaders after he had learned about the appearance of an unknown enemy in the Cave of the Invaders.

In the corners of the library in the Kingdom Metropolis, he flipped through a large number of old books that were not often turned over.

Those old books have multiple references, quoting from ancient texts, or quoting from earlier texts.

Among them, there is a content that mentions the relationship between the cave on the edge of the land and the possible excavators.

"It is written in ancient times that in ancient times, someone entered a cave and found metal behind a stone. At this point, the Chief Scholar of the Kingdom confirmed, "Yes, to be exact, behind the stone, it should be 'metal plate,' although the ancient words are very different from the present ones, but I can be sure that the word is written about metal plates, not metal deposits or the like." ”

"Could it be fiction. Malatinius asked.

"Generally speaking, no, the content of that book is documentary content, and the data of the book cited in it, according to my check, is also a documentary book, and it is a record written after investigation. The Kingdom's Chief Scholar explained.

"Hmm...... Sheet metal?" Maletinous was a little curious.

"Yes, but nothing else, there's no more information. The chief scholar of the kingdom said helplessly, "Those ancient explorers, after discovering that piece of metal, withdrew from the cave - they did not have the tools to excavate, and it was very difficult to excavate the stone with their bare hands!"

"And what about the future? Did they go in and explore again? Did they bring any tools with them?" asked Malatinius, continuing curiously.

"No...... I don't really know exactly why, I think. The chief scholar of the kingdom spread his hands helplessly, "Maybe it's the weather, I see that it snows in the records, maybe ...... Maybe it's something else. ”

"Well, then I have a question, if it is not the strange enemies who have dug the cave, and the people here of us have dug the cave, then whose cave is it so?" continued King Malatinius.

As soon as King Maletinius had spoken his opinion, the people around him began to discuss it softly.

"It may be someone else, but who it is, I think, with my current knowledge, I am far from being able to answer this question!" the Chief Scholar of the Kingdom continued, "This is not my humility, it is indeed the case, those caves are very mysterious, full of unknowns, perhaps, there are many, many more, waiting for us to explore!"

Indeed, there is actually a lot more about this land, which is unknown, and there is still a lot that needs to be explored by the people here!
