A refreshing feeling came over Green as he walked into the storefront.

Suddenly, Green felt something and quickly looked up, only to realize that the surroundings were no longer the same.

Although still in the pond, there had been a huge change in the scenery outside. The quiet forest had transformed into a group of rocks emitting a certain kind of light, along with various pillars exuding a sacred aura, adorned with intricate patterns that Green couldn't understand.

At the same time, Green could clearly sense that something was blocking his perception.

More precisely, the space he was in now was different from before.

In fact, Green had already anticipated this outcome before. Obviously, although the floating island was in the sky, it couldn't be entered without special means.

Green looked around and saw Yuzuriha, who seemed to be clinging to the wall, standing on the water's surface with her arms supporting her.

A faint magical power was attached to her body, indicating that Yuzuriha's magic was at work.

However, source energy could achieve the same effect.

Yuzuriha walked slowly towards the pillars, subconsciously touching the patterns on them, looking surprised.

Curious, Green asked, "What's wrong? Did you find something?"

"I have a strange sense of familiarity... It seems like I've seen it before..."

"Huh?"

Green walked out of the water and curiously examined the surroundings. Besides the glowing rocks and pillars, there was nothing else.

But now, Yuzuriha might know something.

Previously, Azeral had mentioned a sacred pool at the center of the floating island, which was the entrance to the dragon's sanctuary. However, Green had emerged from the pond that resembled the pool, so he was puzzled.

Azeral wouldn't dare to deceive him, but considering the current situation, perhaps he had been deceived.

"Oh, do you recognize these pillars, Yuzuriha? They seem quite sacred."

"No, I can't remember."

Hearing Yuzuriha's answer, Green approached and observed the patterns on the pillars from a close distance.

Soon, Green discovered that each pillar had different patterns, seemingly conveying something or representing something.

Green speculated that these might be the script of the dragon clan, but he was not familiar with the script of even the otherworld, let alone that of the dragon clan.

At the moment, Green was also a bit at a loss.

However, Yuzuriha seemed to have found some clues. Her gaze remained fixed on the patterns on the pillars, rotating back and forth.

After a while, Yuzuriha's eyes suddenly lit up, and her expression changed noticeably.

"Come here."

"What's wrong?"

Green stood up from the pile of stones and walked to Yuzuriha's side.

There was a particularly tall pillar in front of the two of them. It was conspicuous, but Green hadn't noticed anything even after staring at it for a long time.

But judging from Yuzuriha's appearance, she had discovered something that he hadn't.

Yuzuriha's hands were enveloped in a layer of magic as she slowly placed them on the patterns on the pillar.

Immediately, the patterns started to flicker with a golden sacred light and quickly connected to the patterns on several other pillars, forming a group of interlinked stone pillars within a few seconds.

After the golden light had persisted for a few more seconds, Green noticed that the nearby pond suddenly emitted a golden light.

"What is this...?"

In fact, Green had noticed a long time ago that not only Yuzuriha but also Mio had a slight difference in their magic compared to ordinary people.

Now witnessing Yuzuriha's actions, it was undoubtedly clear that this mechanism required the input of magic power to activate.

And now, the mechanism had been activated, and it seemed that some change had occurred to the pond's surface.

Green came to the vicinity of the water, which was shining with golden light. He reached out and fished in it, only to find that it was not water at all, but something visible but untouchable, like a virtual image.

However, just as Green was preparing to jump in and take a closer look, he realized that it was not an entrance at all, but a trap that could take lives.

To explain why, a muddy figure suddenly emerged from the golden holy pool, proving it best.

Green immediately stepped back and instinctively protected Yuzuriha behind him.

These sand people had sand flowing like water all over their bodies, and their appearances were quite unusual. They looked like some kind of humanoid machinery, but made of mud and sand instead.

Just then, the patterns on the stone pillar began to glow and gradually gathered and formed a text in the air above the sand people.

Green couldn't understand the text, but Yuzuriha instinctively read it out.

"Defeat the sand guardians to prove yourself," she said.

"I see, it's similar to what I thought," Green replied.

After receiving Yuzuriha's information, Green looked at the sand people, who were entirely made of sand except for their glowing red eyes, and revealed a dangerous smile.

However, before Green could make any moves, he suddenly heard a loud rushing sound in his ears.

Feeling confused, he noticed a turbulent torrent rushing from behind him towards several sand people, and then...

There was no "then".

The sand people disappeared, but a pile of wet sand appeared at the edge of the pool.

Green turned and looked at Yuzuriha behind him. Her hand was still outstretched, and she exuded obvious magical power.

"I almost forgot how strong you are..."

"Hehe..."

At the same time, the golden words in the air disappeared, but the illuminated pool remained unchanged.

Green didn't ask any more questions and jumped into it directly.

When Green jumped into the golden pool, he found himself in a strange space, as if he was swimming in an ocean of golden light.

But this amazing sight was short-lived, and after a few seconds, Green found himself standing on a flat ground.

The scene in front of him shocked Green.

The first thing he saw was a tremendously large sphere floating in the air, surrounded by a golden halo. The overwhelming pressure it emitted made it hard to breathe.

Not only that, Green looked around and found that these giant, glowing spheres were everywhere.

The only part that could be considered the ground was the spot under his feet.

"Yuzuriha, where are we?" Green asked.

"I don't know..."

Just when both of them were confused, a huge shadow of a dragon suddenly appeared before them.

It was the shadow of a golden dragon, similar in appearance to the Flame Dragon, exuding a very imposing aura.

At this moment, the golden dragon looked at the two and spoke.

"Congratulations on successfully arriving here. This is the holy land of dragons, also known as the Sanctum. According to the rules of the Sanctum, any human who can pass the trial here will have the opportunity to make a contract with a dragon. See those giant spheres of light? Choose one, enter it, and conquer the dragon inside, becoming its summoner."

Without giving Green any chance to ask questions, the shadow of the golden dragon disappeared instantly after explaining, leaving the two in awe.

Green looked at the countless giant spheres of light, and let out a deep sigh.

"It seems like we've come to a very majestic place."

These giant spheres of light had different colors, although some of them appeared similar, careful observation revealed slight differences.

Not only in color, but also in size and the number of halos, they were all different.

There was no doubt that these represented information about the internal dragons.

After being indecisive for a while, Green finally followed Yuzuriha's advice and set his gaze on a silver-white sphere in the distance.

The silver light body is not just one, but there are many halos on this one. Green guessed that the creature inside might be very strong, and judging from the color, there is a high possibility that there is a silver dragon inside.

After all, these colors are so distinct, it's hard not to make such an association.

"Let's go, let's go and take a look."

After approaching the silver giant light body, Green found that when he got close to a certain distance, his vision would be blinded. However, when he moved back a bit, his vision would return to normal.

Green tried several times and finally concluded that he needed to move back about fifty meters to restore his vision after it was blinded.

It's quite fun, to be honest.

But they cannot waste time on this. After satisfying their curiosity, the two entered directly.

Now they can't see anything, they can only sense each other's presence, and there is nothing else.

Yuzuriha started to panic, but luckily she leaned towards Green's direction, feeling his presence clearly.

This reassured her a lot.

Finally, after about half a minute of being blinded, their vision returned.

The first thing that caught their eyes was a massive waterfall, with mossy steps on both sides. Below the waterfall was a shallow pond, with an unknown structure in the middle.

Green didn't understand what this thing was, but his intuition told him that as long as he caused trouble, it would be right.

Acting on intuition is one of the unreliable traits of Green, but he didn't care.

Seeing the seemingly man-made facility in the middle, Green's desire for destruction erupted like a swollen volcano.

In an instant, Green locked his gaze on that facility.

"...?"

Yuzuriha, who was next to him, seemed to have noticed something. With a confused look in her eyes, she glanced at Green and saw his eager expression.

"Yuzuriha, do you know what that thing is?"

"I don't know..."

Upon hearing Yuzuriha's response, Green directly fired a source energy blast.

Just like when they destroyed the forbidden bookshelf Yuzuriha used to guard, with a flash and a booming sound, the waterfall was forcefully pushed up by the source energy, and a huge door appeared in front of them.

"Uh..."

Green was stunned when he saw this scene. It was clear that the door was hidden behind the waterfall, and it didn't appear as a result of destroying the facility in the middle.

At that moment, Green sensed a terrifying aura coming from behind the door.
