However, Fire Feather doesn't seem to care that his lair is deserted.

It led everyone to the open space where the spirit crystals were kept.

"Senior brother, what are Huo Yu bringing us here for?" Xinluo said.

"It seems that they are looking for something!" Cheng Yu didn't quite understand what Huo Yu wanted to do, but he knew that Huo Yu was going to bring them to find something important.

"Looking for something, could it be that Huo Yu left a treasure here before?" said Xinluo with a smile.

"That may be true, people are not only stronger than you, but also smarter than you, and it's not unusual to leave a treasure here. Xinmei smiled.

"Senior sister, why do you always compare me to Fire Feather?" Xinluo said speechlessly.

"Think about this yourself!" Xinmei shook her head.

Everyone saw that Huo Yu came to the middle of the clearing, Cheng Yu knew that that place was the place where the largest spirit crystal was originally placed, and he didn't understand what Huo Yu was looking for.

Suddenly, Huo Yu pecked the ground a few times with his pointed beak, and then shouted at Cheng Yu.

"Senior brother, what did it say?" everyone said curiously.

"It said, there's something down here!" Cheng Yu walked over, looked at the place where Huo Yu pecked with his mouth just now, and said.

Cheng Yu pushed the soil away, and what appeared in front of everyone's eyes seemed to be a stone slab, so everyone helped together to shovel all the soil in the same area.

At this time, everyone finally saw clearly, this is a large stone box of about one square meter.

There is a strange little door on the top of the stone box, that is, on the top of the stone.

"Ha, it turns out that Huo Yu really hides a treasure! hurry up and open it and take a look!" Xinluo said in surprise.

"No, there is a prohibition here to protect this stone box!" Cheng Yu wanted to open this small door, but surprisingly, this stone box seemed to have a strong prohibition, so there was no way to open this small door.

"Senior brother, hurry up and open the ban to see what treasure is hidden here?"

"Huo Yu, can you open this ban?" Cheng Yu tried it himself, but he couldn't open this ban, and immediately looked at Huo Yu.

Since Fire Feather brought them in search of this thing, maybe Fire Feather knows how to open it.

However, to Cheng Yu's disappointment, Huo Yu just shook his head and screamed a few times, obviously, it didn't know how to open this stone box.

"It seems that we can only figure it out on our own!" Cheng Yu said helplessly.

Prohibition is like tying something with a rope, except that instead of thread, it uses aura. The more knots you tie, the stronger the ban becomes.

However, they can't really be like untying a rope and cutting it with scissors if they can't untie it. However, they can also use violent methods to directly break the ban with great strength. It's just that if you want to use this method, the strength of the forbidden breaker must far exceed that of the forbidden spellcaster.

Obviously, the prohibition that protects this stone box now is like a rope with many knots, even dead knots, and it seems that they can't untie this prohibition with their abilities.

Moreover, Cheng Yu does not have the ability to directly break this ban, which is a bit troublesome.

"Cheng Yu, why don't you let me try it!" At this time, Xinyun said.

"It's okay! Senior Sister seems to have a deep study of the prohibition, I hope Senior Sister can unlock this prohibition!" Cheng Yu nodded and stepped aside.

Xinyun is actually a very capable person, basically involved in many aspects, and has some achievements.

However, this prohibition is obviously not as simple as imagined, Xinyun was relieved for a while, and the forehead was already sweating, but it still hadn't been lifted.

"Senior sister, can you untie it?" asked Xinhai a little anxiously.

"Wait!"

An hour passed.

"Senior sister, how is it?"

"Wait!" Xinyun looked a little tired, but she still didn't give up and was ready to continue.

"Senior sister, if it doesn't work, forget it, let's think of another way!" Cheng Yu was a little unbearable and said.

"Give me some more time!" Xinyun is also a person who does not admit defeat, and the more difficult things are, the more he likes to challenge!

She enjoyed the feeling of untying the knots one by one, so although she was tired, she still didn't plan to give up, she felt that as long as she gave herself enough time, this prohibition would definitely be able to be untied.

The crowd had no choice, but they were afraid of disturbing her, so a group of people walked a little farther away and prepared to eat. Anyway, all the territory on this island is Fire Feather, except for the Fire Giant Bird, there are only some small animals left, and there is no second kind of magical beast.

So they are not afraid that anyone will disturb or cause harm to Xinyun.

"Senior brother, can senior sister really unlock this realm? It's been almost a day!" Xinhai stuck a hare on the barbecue fork, kept turning the barbecue grill on the fire, looked at it and was still immersed in the process of lifting the ban, and said helplessly.

"It should be possible!" Cheng Yu said uncertainly.

But seeing that Xinyun is so serious, he really hopes that she can unravel it.

"We are now already at the strength of the Merge Period, and this prohibition is so difficult, it is very likely that it was arranged by the masters of the Mahayana Period. Kokomi said.

"I'm afraid it's more than that! If it's arranged by the Mahayana period, maybe I can unlock it, I guess this prohibition is at least set by the masters of the Tribulation Period!" Cheng Yu shook his head and said.

"Tribulation Period, that Senior Sister Xinyun can solve the prohibition arranged by the master of the Tribulation Period?" Xinhai said in surprise.

"I think it's a bit mysterious, this prohibition is not simple at first glance, the things in the stone box must be very precious treasures, otherwise they would never use such a powerful formation to protect it!" Xinluo said.

"What kind of treasure do you say is in this stone box?Senior Brother Yu, did Huo Yu tell you what is inside?" Xinhai asked curiously.

"No, Fire Feather only knows that there is treasure down here, but he doesn't know what's inside. After all, this treasure is not hidden by Huo Yu, and he has not seen others hide it underneath, so naturally there is no way to know!" Cheng Yu shook his head.

He had already asked Huo Yu, but unfortunately he didn't know it, and he could just feel that there was a treasure down here.

"I guess there's a good chance it's a sunshine mirror that opens the sky!" said Kokomi laughed.

"Yang, you are big, how can there be such a coincidence in this world, we are looking for a yang mirror, and the result is a yang mirror?"

"Not necessarily, life is so wonderful. Senior sister, if you think about it, people may not know what the Open Heaven Mirror looks like all their lives, and they don't even know that the Open Heaven Mirror is composed of seven fairy mirrors.

But what about us? Not only do we know that there are seven fairy mirrors in the Open Heaven Mirror, but we have already found six, is there anything more related to the Open Heaven Mirror in this world than us?
