Duan Yiwei obediently focused on healing his injuries. The others looked at the whistle and didn't dare to touch it again.
Yun Jin herself was also completely confused. She tried several more times, even changing the way she blew the whistle, but no matter what she did, the whistle just wouldn't make a sound.
Even Tianpo couldn't figure out what was going on.
They stayed on the coast for about an hour. Just as everyone was thinking about how the whistle could be blown.
Suddenly.
In the distance, the surface of the sea surged violently, and terrifying waves rose into the air.
The waves were over a thousand meters high. By the time everyone sensed them, the raging water had already swept in front of them.
What kind of situation was this?!
Everyone panicked and hurriedly took to the air.
However, their speed in flying upward was still slower than the speed at which the waves swept in. They were forced to struggle within the surging waters, each using their own abilities, desperately trying to break free.
Duan Yiwei worried that Yun Jin's cultivation was too low and even considered whether he should look after her a bit. After all, this is a critical moment for opening the secret realm. If something happened to Yun Jin now, it would only make things more troublesome.
As a result.
The whistle in Yun Jin's hand suddenly flickered with light, enveloping her and the people around her. The massive waves were completely unable to reach her.
Duan Yiwei's expression shifted slightly. Could these waves have been caused by the whistle?
But there was no sound from the whistle at all!
What connection could there be between these waves and Wushuang Sect?
With these doubts in mind, everyone flew higher into the air.
Fortunately, aside from being enormous, the waves didn't seem to possess any actual offensive power. Everyone present was a cultivator, so they weren't actually afraid.
Yun Jin focused her gaze forward.
Faintly, amid the surging waves, she saw what looked like an island.
The island moved through the wind and waves, slowly drifting closer.
Finally.
Before everyone's astonished eyes, the island reached the shore and came to a steady stop.
The waves gradually calmed down as well.
Everyone descended back onto the coast, each filled with uncertainty.
An island… that could move?
That didn't seem very logical.
At that moment.
In front of the island, a gigantic head suddenly emerged.
With a slight shake of that head, dozens of meters of waves were stirred up.
A colossal creature slowly surfaced from the sea.
Only then did everyone see clearly.
This was no island at all. It was the back of a giant turtle.
The turtle's body was over a thousand meters long. Just its massive head alone was likely a hundred meters in length.
Not only Duan Yiwei and the others, even the Mahayana Stage cultivators from Yuehua Sect couldn't help but tense up.
This giant turtle was so enormous that it looked as though it had lived through countless ages.
As for its strength?
It's likely extremely terrifying!
At the very least, even those Mahayana Stage cultivators, no matter how hard they tried to sense it, couldn't probe the giant turtle's true depth.
The giant turtle turned its head slightly. After confirming something, it slowly crawled out of the sea. With even a small movement, another towering wave was stirred up.
Protected by the whistle, Yun Jin remained completely unharmed.
The giant turtle moved quickly. After crawling for a short while, it stopped in front of Yun Jin and spoke in a deep, booming voice, "Lightning respectfully welcomes the Little Master."
Yun Jin: "..."
No wait, with your speed, you're called Lightning?
Lightning seemed to sense Yun Jin's thoughts and said a little embarrassedly, "This name was given to me by my benefactor. It is indeed very fitting."
Everyone: "???"
Fitting?
Yun Jin was also doubting her life at this moment.
Hadn't Tianpo said that his master was mature and reliable?
Looking at this now, it seemed that he also had a bit of mischievous taste.
But.
That's not important.
What mattered was that this giant turtle seemed to be some sort of guide.
"Lightning, are you here to take us to the location of the Wushuang Sect secret treasury?" Yun Jin asked curiously.
Everyone else looked over as well.
Lightning shook his head, "No."
No?
Yun Jin couldn't help feeling puzzled.
Lightning continued, "I carried the secret treasury here. Where I am is the location of the secret treasury."
Everyone froze, then collectively looked toward the island on Lightning's back.
This island… was the location of the secret treasury.
Earlier, everyone had been so shaken by the giant turtle that they hadn't examined it carefully.
Now, as they looked more closely, they began to sense something unusual.
The island had cut through wind and waves to arrive, yet it had been perfectly preserved. Not even a grain of sand seemed to have been lost.
This was… protected by a specially arranged barrier?
Duan Yiwei narrowed his eyes and gave a signal to someone from Yuehua Sect.
This time, he had learned his lesson. He didn't plan to test it himself, he let someone from Yuehua Sect check it first.
A Fusion Stage expert from Yuehua Sect stepped forward and reached out to touch the island.
However.
His hand passed straight through a tree.
"Illusion!" Ye Liuqin exclaimed.
The island looked so real, yet it was actually just an illusion.
The true secret realm hadn't been opened yet.
Tianpo's proud voice rang out in Yun Jin's mind, "My master cultivated a bit of Space Dao. Through it, he could lock onto weak points in certain secondary-dimensional spaces and transform them into secret realms. This island is merely a distraction. The real secret realm doesn't even exist within this world. Based on my understanding of my master, he must have found a secondary-dimensional space and hidden the secret treasury within it. To enter that space, all five keys must be gathered."
So that's how it was.
Yun Jin nodded.
The whistle in her hand seemed to respond to something. It rose into the air again, transforming into the form of five keys.
"This is the key to opening the secret treasury," the giant turtle said with a nod. "Little Master, and the other holders of the keys, stand within the light circles beneath the keys according to their positions. Those you choose to enter the secret realm with you should also stand within the corresponding circles."
Yun Jin nodded.
She led Yue Zhao and the others to stand within the light circle beneath the central main key.
After that, the people from the four great holy lands each took their positions in turn.
"Key holders, infuse spiritual power into the keys," the giant turtle instructed.
Everyone followed the instructions.
As spiritual power flowed in, the colors of the keys began to change.
Yun Jin stood at the center, holding the earth-attributed yellow key.
The other four were the eastern water-attributed key, the southern fire-attributed key, the western wood-attributed key, and the northern metal-attributed key.
As the Five Elements manifested, a massive door appeared on the back of the giant turtle.
The door corresponded to the positions of the five keys.
The five keys rose into the air and inserted themselves into their respective keyholes.
The next instant.
The massive door opened.
Everyone leaned forward to look, yet they saw nothing at all.
Behind the door seemed to be a swirling vortex passage.
The giant turtle said, "Entering this passage will take you to the true secret realm."
In Yun Jin's mind, the system's prompt sounded.
"Detected S-rank secret realm: Wushuang Sect Secret Treasury."
Yun Jin's eyes flickered slightly.
S-rank.
This was merely something hastily arranged by a clone of the Sword Sage of Ten Thousand Daos in a short amount of time, yet it's already an S-rank secret realm.
If it was the true Wushuang Sect located at Cloud Sea Mountain, wouldn't it be an SSS-rank secret realm?
The Wushuang Sect secret treasury was now open.
Clearly, entering it would lead directly into the secret realm.
Yet the atmosphere on the shore suddenly grew tense.
