Hearing that, everyone turned to look at Aya.
"I have set up a teleportation formation near the entrance. If you want to go back, I can directly send you out now," Aya said slowly and she looked at her friends.
At this moment, she could clearly feel that the ghost aura in this ghost realm was increasing at rapid speed.
She could guess that it was time for these ghosts to appear and it would be impossible for her friends to go out safely using the normal route. Since she had brought them here, then she would be responsible to send them out.
Even though Aya didn’t really want to expose her strength, but she knew very well that it would be impossible for her not to.
"Teleportation formation?" Leon, Dean, and Yun’s expressions changed when they heard this. They have never heard of Aya knowing any high ranking formation before. Moreover, a teleportation formation was a very high level formation that not many people have the chance to learn in their entire life.
How did Aya learn it in the first place?
Only Evan was more or less prepared.
This was because he had already seen Aya’s formation in the past. The training that Aya gave to him before that competition was deeply ingrained in his memory. He knew very well that his cousin’s sister’s ability in formation had far surpassed many other people.
But before she could explain, the ground shook.
Everyone who was within the valley’s area were stunned and staggered, trying to use their mana to stabilize their body.
And then they watched as a large building appeared from the ground in the middle of the valley with an extremely large door opened for them. Everyone turned their eyes to look at the building that suddenly appeared in front of them.
"Is this the secret realm’s biggest opportunity?" Leon asked, his tone was laced with eagerness. If he could get something valuable from inside... doesn’t it mean that he would be able to improve his strength leaps and bounds?
As for the danger that might accompany him?
How could there be any chance without danger?
"Perhaps." Aya looked at the building in front of them warily. They were still a few kilometers away from the building, but they could see that the building was extraordinary. Moreover, Aya could tell that this building contained a thick ghost aura.
How powerful are the ghosts inside for the ghost aura to be so thick?
Moreover, this building looked very large and Aya guessed that people who were still a distance away from this valley could see it too.
At that time, they would definitely be attracted to this place.
There might truly be some chance.
Aya’s eyes flickered.
"Do you want to enter?" Dean asked as he looked at the building. While the danger just now made him a bit hesitant, but he was also eager to increase his strength. Their purpose when they came to this secret realm was to get resources and increase their strength.
Since there was a chance presented to them...
How could they be willing to look away?
Yun pursed her lips and felt uneasy, but she looked at the others.
"This..." Evan looked at the building and then thought about the puppet they brought in. He took a deep breath and then looked at his cousin’s sister solemnly. "Aya, if we were to enter the building... can you still make the teleportation formation for us to get out?"
"I can," Aya said calmly.
Unless the building contained space confinement formation, which meant that she has to break it first, Aya was confident that she could send all of them back safely.
Seeing the look of the three boys, Aya sighed deeply in her heart.
She knew very well that these three boys didn’t want to return but want to continue and explore the building for more chances to get stronger.
"Shall we try to enter?"
With that, the five of them rushed over to the building. However, they were not in a hurry and controlled their pace because they could guess that there might be other teams nearby who would come and try to get into the building.
Rather than having conflicts with them, it would be better for them to be careful.
At the same time, they were also silently meditating while walking. The meditation was not very good, but it would increase the speed in which their mana recovered.
Soon, they reached the building.
Along the way, Aya had noticed that there were at least three teams that entered the building before them. It could be seen that the attractiveness of this building was very high.
After all, in the entire ghost realm, there were no other buildings nearby.
They could only see forest, stones, and other things that was commonly seen in nature.
But this building was clearly the product of manmade.
So everyone was curious.
As they reached the entrance, Aya nodded and they all walked inside. The moment they walked inside, they could feel the temperature was going down at rapid speed and there was a door heading down.
Even though it looked a bit eerie for some reasons, they have no reasons to back down.
Everyone walked forward and entered the door and continued to walk forward.
What greeted them was a corridor with four directions that they could choose.
"This... which way to go?" Evan asked.
"Let’s try one direction." Aya looked at the corridor and sensed that they all looked the same. It would be impossible for them to know what awaited them at the end of the corridor, so they could only choose one of them.
This four directions also meant that they might not pick the same route as the groups who came before them.
The five of them finally decided to pick the south one.
