Walking on the delicate and classical spiral staircase, Ian couldn't help but admire the murals on the inner wall of the Fallen Star Tower. Pen % fun % Pavilion www.biquge.info

The frescoes painted on the sides of this staircase stretch continuously, almost like an epic picture scroll spread out, sacred and solemn. Meandering up the staircase is like telling a legend buried in history to passers-by on this staircase.

Along this scroll, he saw the invasion of the devil on this world and saw the appearance of the able. I saw people working in their own way, struggling powerlessly under the scourge of natural disasters. I saw a king who unified everything, brought together countless peoples, and established the first and only empire in history that integrated everything.

Although this empire is so small for the entire continent, it has preserved the fire of humanity and left the hope of the world's continuation.

"Why do you want to come to such an important place?"

Seeing this, he looked at the back of the Grand Duke walking in front of him, and couldn't help but ask this question curiously.

He knew that the Falling Star Tower was the most important building in the Northern Regions, and he knew that there were legendary Source Crystals and Prismatic Cannons that were rarely seen by ordinary people. However, he didn't know why Khan Parks had brought him here.

He couldn't understand the reason for this, he was not a nobleman, nor was he a high-level, he was just a boy from a commoner family, who had a little adventure and became a disciple of the Sword Saint.

"Although you are far from mature enough, you are also a high-level powerhouse. The Grand Duke slowly spoke: "So I think it is necessary to let you know some important things in the Northern Regions, so as not to make trouble when the time comes." ”

"As long as it's the superior who knows?" Ian asked in a skeptical tone.

"Of course not. The Grand Duke sneered: "Until we confirm our identities and determine whether they are reliable, even if we are in a higher position, it is impossible for us to reveal these to him." ”

"Is that so?" said Ian, who had a vague sense that Khan Parks had other meanings in doing so, but it was clear that the other party wouldn't tell him now.

"Of course. Khan Parks replied casually, without any further meaning. In silence, the two men continued to climb upward, and after a while, Ian suddenly felt a different light from the crystal lamp above.

"That's?" Ian wondered. Because the light escaped through the rock from the floor above!

What kind of light can even shine through rocks?

"That's the light of the source crystal. ”

"Yuanjing?"

"Come on, ordinary people can't see Yuanjing. At the end of the spiral staircase, Khan Parks stepped onto the platform at the top of the tower and turned his head to give an inviting smile.

Ian was slightly stunned, and quickened his pace towards the soft but not more tenacious light, and followed Khan Pax to the platform at the top of the tower.

A bright, yet unblinding light source captured all of his attention at this moment.

It floated silently in the center of the platform, and countless silver threads extended from the source, spreading to the entire tower, and then radiating to the entire northern region with this tower as the source.

"Is this the Source Crystal?" Ian muttered, but Khan Parks shook his head slightly, he walked up to the whole place, picked up the diamond-shaped crystal that had opened the tower earlier, and stretched out his hand, as if unveiling a light veil, letting go of the last layer of enchantment that wrapped the Source Crystal, revealing the true form of the Source Crystal in front of Ian's eyes.

At this moment, with a confused gaze, he said in an extremely pious and even fanatical tone: "This is Yuan Jing. ”

The greatest mystery in the world is finally revealed in front of Ian.

It was a white-gold flame encased in hexagonal crystals.

Ian believed he would not be mistaken, the real source crystal was not a crystal with a small flame inside, but the flame that was encased in the crystal.

Because that flame not only exudes unparalleled energy, but also seems to contain all the truth in this world.

For a moment, both Ian and Khan Parks couldn't help but lose their minds.

The level of technology in this world is extremely strange.

Some places are as backward as the ancient times of the earth, lighting the light with candles, cooking with firewood, and walking through the countryside with the strength of their feet and horse-drawn carriages.

However, there are places that seem to be at a level similar to that of the earth's industrial age. Lanterns for lighting were born here, production activities were carried out with machinery that was very different from the previous life, and although there were no so-called guns, televisions, or automobiles, there were empty ships that could float on the clouds, and heavy but powerful cannons.

The reason for all this, replacing the status of coal and electricity on the earth, is the source crystal, the legendary near-infinite, even eternal energy source.

As long as it is not used excessively at one time, the energy in the source crystal will be far from continuous and will never be exhausted. And even once all the energy bursts out, after a period of silence, it will be rekindled, and gradually return to eternity and infinity again.

Such energy cannot exist on Earth, where infinity and eternity are paradoxes. However, in this world, there is such an energy body.

As long as there is only one source crystal, it can not only support the mental image sealing array that covers a domain, but also support the energy demand and industrial operation of this entire domain.

It's an incredible thing.

"Yuanjing, this is Yuanjing. It took a long time for Ian to come to his senses, but he couldn't help but mumble to himself.

"That's right, this is the source crystal. Khan Parks nodded, and began to speak in an inexplicable tone: "This is the endless energy that the fire thieves are searching for outside the circle, and just one can open up a domain. ”

"Fire stealer?" Ian was slightly stunned, he had heard the word in Lilith's recollections, but he didn't expect to hear it again here.

"Source Crystal is the lifeblood of human civilization. The Fire Thieves are a group of the strongest of the powerful except for the strongest, and their mission is to go deep into the territory occupied by the demons outside the circle to find the location of the source crystal, and bring it back to the empire as much as possible. ”

"In this world occupied by demons, Source Crystal is one of the two necessary conditions for humans to counterattack demons and regain lost territory. ”

"Take back the land?" Ian was stunned, since the appearance of the demon, humanity has been only defeated, except for the only one more than 400 years ago, there has never been a word of regaining the territory.

And what he recaptured that time was precisely the northern region under his feet.

This is also the reason why the Northern Regions are so small, but they can be classified as a separate domain.

Because he has too much meaning for human beings.

This is the first time that humanity has taken back from the clutches of demons!

"yes. Khan Parkes sighed with emotion: "Only by using the source crystal can you set up a mental image sealing array to avoid the territory from endless attacks by demons, so as to stabilize the territory of human civilization." ”

Therefore, in ancient times, the source crystal was also called: fire. ”
