The Sword and Shield Fortress is like a huge barrier across the north and south, from the ground to the sky, this pure war fortress with no regular shape at all is attached to the center of the two mountain ranges, completely dividing the north and south of the continental plate. The legendary story about this fortress is familiar to almost every human being, in the first wave of monsters, in the hundreds of years of war, the safety of the human race was entrusted by such a scarred fortress, this hundred years of unbroken fortress has almost become a kind of faith.

However, the faith was finally shattered by the turbulent tide of the monsters, and when the people in the northern transfer zone learned that the sword and shield fortress had been broken, almost no one believed it, but just when the monsters were rushing like broken paper, the human race was finally awakened to the pain that had been forgotten, and the war of extermination began again.

But no one in history can say exactly how this legendary fortress was destroyed - because almost no human beings on the front lines of the battlefield survived, and the main thing is that no one has been able to return to this fortress since.

"In other words, we're the first to return to the fortress, right?" The fortress is indeed very powerful, the multi-storey towering city wall is built against the mountain peaks, its height and thickness are more powerful and domineering than all the cities Lin Yao has seen before, and the structure of this fortress is almost the most well-preserved city among the cities he has seen - this is of course thanks to the stability of the fortress itself, but the intact fortress in front of him does not match the appearance after it was captured, Lin Yao frowned.

"I feel like there's a lot of conspiracy in there."

The three-layer city wall inside and outside completely sealed the center of the two mountains, and as far as the eye could see, the number of monsters in the city was not as large as the monsters entrenched in the previous city.

"This fortress is too well preserved...... Refrilyn was obviously aware of this problem, she frowned slightly, "If it had been breached as recorded in history, this fortress would have been razed to the ground by the monsters that came from the north, and it would definitely not have been left intact!" ”

The three of them didn't say much, and flew directly towards the center of the fortress, the filthy magic in the city had not yet reached the effect of causing a magic tide, so the three of them landed on the city wall incognito with confidence.

"Moss, earth...... And mushrooms! There is no trace of monsters passing by. Milou shook off the mud that he had pulled from the city walls and covered his hand with his hand to look at the fortress at the highest point, "Where is our next goal?" ”

Lin Yao closed his eyes and sensed it, and pointed in a direction with his hand, "Take the first book first, the location is not far from us, it should be inside the fortress." ”

The structure inside the fortress is not too complicated, this construction style used entirely for war tools is very rough and simple, the front of the fortress is facing the front of the canyon, and each layer of the structure from top to bottom has various sizes of arrow towers, and there are some platforms for casting spells, and the mage is fighting on this half-height platform that sticks out of the wall.

The three of them flew directly from the casting table to the interior of the fortress, and following the direction of Lin Yao's guidance, the three of them finally found the third book in a room similar to the command post—the book was pressed under a fallen candlestick, and the arrangement on the table remained intact.

It was very smooth to recycle this book into the system, and to recover ordinary books, it was still a thousand points in hand.

Milou picked up a piece of parchment from the table, and looked at what should be a detailed topographical map of the vicinity of the fortress, "There are no signs of a fight, and there is no trace of a monster coming...... It's hard to imagine such a place in a hundred years. ”

The two of them looked around in the room of this command room, and the things in the command room were naturally very simple, except for some daily necessities, there were only some equipment in the army. Touching the armor and shields hanging on the wall, the dust pavement, Retlyn covered her nose, "The people in this fortress seem to have all disappeared all of a sudden, although the things here are messy~, but it doesn't look like they have been breached at all." ”

"These things should be studied by human scholars, and we should pay less attention to these things." Lin Yao shrugged.

Mi Lu also nodded in a deep voice, and after the three of them walked around without a clue, they flew out of the fortress, the position of the second book that Lin Yao perceived was very strange, Lin Yao took the lead in front, flew out of the fortress and flew straight towards the side peak, as the position fluctuations of this book became clearer and clearer, Lin Yao's brows became tighter and tighter.

Just when Lin Yao finally flew in front of the mountain, Lin Yao finally dared to determine the location of the book.

"This book is actually in the mountains!"

The three of them looked up at the peak that reached into the sky, the continuous mountains to the far distance, and the steep cliffs entrusted the fortress to rise, almost like a huge peak covering the sky, and the three of them shook their heads suddenly.

"It doesn't look like you can be in a mountain...... right" Milou hesitated for a moment, then waved his staff, and a huge ice cube rose from the ground and hit the rock cliff, shattering the ice crystals, but the stone wall was only smashed with a few small stones, this method was obviously useless.

Lin Yao watched around the stone wall for a long time, although the matter and energy of this world would not have any contact effect on him, but the high-quality matter itself had a strong spatial repulsion - in layman's terms, his intention to crash into it to see what was going on was ruthlessly denied.

But the scene in front of him obviously revealed a strange situation everywhere, he once again carefully enlarged his perception to the extreme, eliminated all the other distracting thoughts in his mind one by one, and his hands touched the stone wall, just as the clear book signal came, Lin Yao suddenly discovered a different energy reaction from Mr. Yu, and sensed it carefully for a moment, which suddenly made his eyes widen.

"The inside of this mountain is empty!"

Milou and Retlyn glanced at each other in surprise, Lin Yao didn't talk much nonsense, and first flew up the mountain, from the foot of the mountain to the top of the mountain, but still didn't find anything, and then he found a new direction to continue to sense, flying horizontally along the mountain stone wall, he flew straight from under the city wall of the fortress to the direction of the canyon, the feeling in his heart became stronger and stronger, when he finally crossed this canyon that separated the north and the south, his vision suddenly opened up - he finally stood outside this moat!

In the center of the mountain, a huge tunnel mouth runs parallel to the gut of the canyon in front of the fortress, and the tunnel is several hundred meters wide and leads to the depths of the mountain.

Transform the mountain and open up the mountains. The scene of turning over the mountains and seas is close at hand.

Milou and Réfrin gasped and were shocked!
