The star of Hyperion, the western continent, the top of the North Sea.

Looming in the shadow of the vast sea of clouds, the mountains are like huge beasts in the vast ocean, draped in snow-capped peaks to cut through the ocean, and will bury their majestic bodies deep under the sea of clouds. In the sunlight, the peaks of the mountains that pierce through the sea of clouds emerge with pale golden outlines, while the more distant locations, the mountains and the azure clear sky merge to depict the misty and fragmented horizon.

Sneer——!

The sharp roar of the chaotic arrows breaking through the sky suddenly sounded, breaking the silence of the peak that had been silent for thousands of years.

The sea of clouds around the highest peak churned, and a team of 100 people wearing black felt cloaks crossed the sea of clouds, swept up along the steep speed, and landed neatly at the highest point of the peak.

"The top of the North Sea, in the history books of the Temple of Hades...... Where the Tree of Wisdom is located. Oz looked around, looking down at the undulating sea of clouds around him, and his eyes quickly pierced through the snow to lock on to a few specially shaped icicles.

"Let's go!"

With a slight wave of his left hand, he took the lead.

The warriors of the Holy Army moved when they heard the sound, and habitually lined up in the Crescent Moon War, approaching the location of the icicles as if they were facing a great enemy. As they got closer, they discovered that the icicles were not the work of nature, and that there were traces of artificial carving everywhere, and they looked faintly like some style of tower.

In the pale golden sun, seven tall towers covered in snow are connected in a row, casting a mysterious atmosphere over the silent peaks.

"Your Excellency...... Is this what His Majesty is looking for?" the deputy asked in a whisper, following him in a whisper.

"Tower of Secret Keys...... If these are indeed the doors to the Tree of Wisdom, that's what His Majesty wants!" Oz replied affirmatively.

Since the empire was completely locked down and completely isolated, Ivan has been preparing for two things: on the one hand, he mobilizes the forces of the two empires to climb the technology tree frantically, and on the other hand, he has the Holy Army and the Hades Temple all over the world to search for ancient ruins.

He firmly believes that the foundation of Hyperion will not be much worse than the home planet of the Federation. After all, King Amun even has a divine source machine!

In addition to the Divine Source Machine, there must be other ancient weapons and knowledge here—if you collect them all, they may not be inferior to the golden relics that made the Federation rich.

......

"If they're really the Tower of Secret Keys, all we have to do is rotate the pillars in order and the passage to the Tree of Wisdom will open!"

As he spoke, Oz took out the backup of the ancient book from his arms, and gradually frowned against the reality and the distribution of the tower pillars on the drawings: "Are we going wrong? ”

Immediately after, he suddenly seemed to realize something, and clapped his hands violently:

"Instead of rotating a single body, rotate and move these seven pillars, arranging and combining them in the order on the drawing!"

"Quick, don't move it yet!" the deputy immediately commanded.

Since each of the soldiers of the Holy Army had a backup of an ancient book, they all knew how to arrange and combine them. Therefore, after hearing the order, they immediately walked towards the tower pillars in groups of three and two, and began to release the light energy in their bodies, trying to move these ancient ruins.

With the concerted efforts of everyone, the pillars soon came to life, cutting through the snow one by one and arranging them into a trapezoidal combination.

At the moment when the tower array was completed, Oz raised his head perceptively, feeling an unusual aura coming from the sky. It seemed like a calm lake with a stone cast in the middle of the lake, causing ripples in a circle on the canopy at the top of the tower.

......

Immediately after, the canopy seemed to collapse into a gap, the lightning snaked inside, and the surrounding air boiled like water.

In the vigilant eyes of the soldiers of the Holy Army, a red dot suddenly appeared inside the gap, and the red dot instantly turned into a beam of light and hit the center of the tower array. Like falling rocks hitting water, it creates a circle of ripples on the ground, and the ground where the ripples pass instantly becomes transparent.

"What is this?"

"It feels like rubber when you step on it...... The soft ones are very elastic. ”

"Seems to be some kind of protective film?"

On the transparent crystalline ground, everyone didn't dare to move, but could only communicate with each other in a whisper, analyzing the touch coming from the soles of their shoes.

“......”

Oz was silent and did not speak, and stomped lightly, finding that the crystalline ground seemed hollow underneath. Immediately, he took a piece of ice stone from a distance, held it in his hand hard, and smashed it the ground under his feet.

Bang——!

The ice stone pierced through the crystalline ground, leaving a wound that healed quickly and shot deep into the pitch-black depths before a crisp sound was heard.

"What we're looking for, it's likely down there, you stay up there, I'll go down and take a look. ”

After saying this, Oz didn't wait for the deputy to stop him, took a deep breath, and then poured his legs into a deep step. The whole person instantly broke through the ground and fell into the pitch-black space below the crystal ground.

In the darkness, Oz felt like he was in the gut of a creature, his body falling straight down. There was no sound in the ears, as if there was no air flow in this passage. After some time, there was a sudden light below, and an oval exit appeared, and he slid down it.

When he hit the ground, the first thing that caught his eye was the tall rock-clad buildings, surrounded by a quiet greenery, standing silently on the boundless grassland.

In this strange environment, Oz immediately activated his light energy, transforming himself into a bronze giant more than two meters tall. Then fly high into the air and follow the distribution of the buildings to take a closer look at the ancient ruins that have slumbered in the mountains.

Judging from the shape and distribution of the buildings, this should be some kind of large-scale academic exchange place, even if it has been sealed for countless years, through the remains of the building, you can still see the solemn and sacred atmosphere of the past.

However, the beautiful and quiet academic exchanges of the past are now only devastated and the exquisite park is now only a remnant of stone tables, and these silent ancient buildings seem to linger in the whispers of the past, telling the history of this place.

At the center of the complex, which should have been the tallest and most majestic building in the area, only a circular arch stands above the ruins. The arches are covered with vine-like patterns, and in the patterns there are faint antique alphabets—Oz himself is a military general, and this kind of alphabet symbol is obviously completely incomprehensible.

It was supposed to be a very large library - the ruins were littered with weathered books, broken shelves, and broken columns of holy white.

"This is clearly an ancient school! Where is the tree of wisdom...... It seems to have been destroyed by an external force...... Is it the spillover of the war?"

Hovering in mid-air, Oz lowered his height as he surveyed the buildings around the ruins. He found that the damage to the buildings was so severe that the walls were already cracking horribly. I believe that it will not last long, and they will be completely reduced to ruins, just like the central library.

The buildings on the periphery, however, were far less damaged, proving that they had been hit by external forces a long time ago. Perhaps it was that blow that caused this primeval school to sink into the mountain and seal it in isolation until now.

One by one, one by one

After a careful investigation, Oz immediately informed his subordinates on the top of the mountain and asked them to go to the ruins together to investigate clues.

The Holy Cult warriors were ordered to descend from the sky one by one, and immediately swept through the spiderweb-like roads like dark clouds, and the squads covered each other and searched the entire ruins, concentrating on the ruins of the central library.

"Unfortunately, there doesn't seem to be any trace of the Tree of Wisdom here. The deputy took a stone box in his hand, walked to the circular arch, and said to Oz, who was in a daze:

"But we found this!"

As he spoke, he opened the stone box in his hand, and saw a ring in the box—made of white-gold metal, with a purple oval jewel around the band like ivy.

"Huh?"

Oz looked at the stone box when he heard this, and was immediately attracted by the ring, carefully took the stone box, and looked at the pattern on the ring. Suddenly, his eyes lit up, and he handed the stone box to the deputy, and at the same time pointed to the ring arch and said:

"You see, if they are exactly the same. ”

“......”

When the deputy heard him say this, he immediately leaned over, his gaze alternating back and forth between the ring and the arch, and finally nodded vigorously:

"You're right, exactly the same!"

"Quick! Shoot down these patterns, and these characters, and write them all down, and give them to the people of Hades' Temple for translation. They have collected so many ancient books, there must be this kind of writing in them!"

......

After the information reached the temple of Hades, Xia Li and a large group of priests rummaged through the library for seven days and nights, and finally found the origin of the characters: a character that was changed from cuneiform, which translates to mean - wearing a ring and leading to the door of wisdom.

"Wear a ring...... A gateway to wisdom?"

Oz groaned for a moment, placing the ring on the middle finger of his right hand and walking to the circular arch in the center of the library's ruins.

"Think about it...... This arch, like the seven pillars outside, may actually be some kind of teleportation device!" He walked directly across from the circular arch and, with the last glimmer of hope, pronounced the syllables of the ring symbol against the pronunciation of the Temple of Hades.

“альные...... клца...... вора...... мудсти。 ”

With a lengthy incantation, a wonderful light surged from the ring, and in the next moment, the ruins of the entire library sank into the ground, along with the hundreds of Holy Army warriors within.

"What's going on!?"

"Was there an earthquake? Or is there some trap?"

"We're sinking...... No! The entire library is sinking. ”

The knights reacted very quickly, and as soon as they sensed that something was wrong, they flew into the sky with light energy. Looking at the slowly sinking library, the group soon realized that this was not a trap, but a very simple mechanism, so they kept their distance and followed the library down to see what secrets were hidden in the ruins.

About half an hour passed.

When the library finally stopped sinking, the Knights found themselves in a much larger space.

In front of their eyes is a city of books!

The heavy and tall pure gold bookcases are arranged in a circular pattern throughout the circular square, and when you look down from the dome, they resemble the roots of a huge tree—the rings of growth rings on the surface of the roots are those well-preserved bookcases.

Sleeping in it is the library deliberately sealed by an ancient civilization.

Oz and his men wandered through the stacks and found books written in Menes, from primeval histories to forbidden spells, from tattered alchemy fragments to endless pages of fiction, from the travelogues of ancient travelers to detailed studies of the planet's interior......

Even these big men and coarse men who held military positions could only express their sincere admiration when they witnessed all this.

In the center of the stack, they found an altar made of vines, a blue-white flame dancing inside the altar, and a bright red flashed from time to time in its core.

It looks like a rainbow compressed!!

"It's been so many years, and it hasn't been extinguished...... Definitely a treasure!" Oz stared at the altar intently, his expression becoming solemn: "Quick! Hurry up and inform the royal court, just say that we have found an ancient ruin of great value!"
