Yuan Zhen probed around the eye of the array he said, and he actually wandered around here for an hour in a small place, and even ignored Xiao Nan's questioning during this time, obviously all his mind was focused on this array.

And Meng Yingru just walked back and forth in this cave sometimes frowning and sometimes smiling, and searched around in the bare cave. Xiao Nan didn't pay attention to Meng Yingru's movements, he kept watching Yuan Zhen paddling around the array, he was confused, but there was no way, even if he asked Yuan Zhen, Yuan Zhen didn't care about answering his question at this time.

The green crocodile was very idle at this time, squinting a pair of big eyes and lying in the corner of the cave to pretend to sleep.

"Xiao Nan, there is a small cave here, it seems that something was in it, but now it is gone!" Meng Yingru suddenly stopped and stood in front of the mountain wall opposite the cave entrance, and said loudly to Xiao Nan.

"Oh, really, the shape of this hole looks like a rectangular object, and it should be upright and fitted into it. Xiao Nan came to Meng Yingru's side, looked towards the place where she fingered, and saw that there was a small hole one meter square at the place where the ground and the cave wall bordered, and the edges and corners of the small hole were sharp, and there were obvious traces of objects rubbing back and forth in the hole! Xiao Nan lay on the ground and looked inside, only to see that the hole was dark, and he couldn't see how deep the bottom of the hole was, Xiao Nan leaned out his divine sense and looked inside, only to see that this small hole was two feet deep, until the bottom of the hole was one meter square, and all of it was neatly cut, and there was no interesting roughness!

"Green crocodile, do you know that there is a small hole here?" Xiao Nan saw that the thing was sleeping in the cave. Screamed at it.

"There's nothing unusual about this little hole, the little one has long known about its existence. The green crocodile walked up to Xiao Nan and said.

"Do you know if there is anything in this cave that can fit into this?" Xiao Nan thought to himself, since this guy knows that there is a small hole here, when it first discovered the location of this teleportation array, didn't he find that there was anything that could fit into the small hole?

"There was a stone bar here, but the small one took it outside to block the hole, and the hole would flood into it whenever there was a storm at sea. Poison gas was put in the cave, so the little one plugged it. The green crocodile said nonchalantly.

"Xiao Nan, is it the stone bar when we came in?" Meng Yingru didn't dare to talk to the green crocodile, she felt panicked when she saw the monster's appearance, so she asked Xiao Nan.

"Well, it looks like that's it. Xiao Nan suddenly discovered a problem at this time, when he and Meng Ying came down, the entrance of the cave was only about one meter in size, and then how did the huge body of the green crocodile get in and out of there?

"Green crocodile. Go and get that stone bar!"

"Yes, I thought I'd go get it. The green crocodile promised to run out, for fear that Xiao Nan would be unhappy if the speed slowed down.

"Xiao Nan, do you think there is still an exit here, or how did that demon beast get out?" Meng Yingru also found that the shape of the green crocodile was disproportionate to the entrance of the cave.

"There must be an exit, wait for the green crocodile to come back and ask. Xiao Nan said affirmatively.

"This girl has always been very strange, what kind of demon trick did you kid perform, and you made that monster listen to you in an instant?" Meng Yingru dared to ask the question in her heart.

"Hehe, this. Secret!" Xiao Nan smiled mysteriously, he couldn't pass on this kind of exercise, this was taught to him by the sentence, he didn't want exercises such as the Dragon Secret Technique to be obtained by himself, and he had the final say in whatever he wanted.

"Don't talk about it, now this girl is getting more and more scared of being with you. I don't know when Lu Dao will let your kid control it and turn into the appearance of that demon beast. Meng Ying muttered.

"Hehe, don't worry, this son has not been obscene to such a situation, and the dream girl will not mess with this son. Ben Gongzi will not make a move on the dream girl. Xiao Nan saw that Meng Yingru was afraid that she would control her, and couldn't help but smile secretly in her heart, not to mention whether the Chaos Imperial Beast could be used on people, but even if Meng Yingru was now her partner, she would not make a move on her, but since she was afraid, it was just right to shock her mind at this time, so that she would not go against herself!

"Master, bring it!" The speed of the green crocodile was indeed not slow, and it only took a while to take the stone back and put it next to Xiao Nan.

"Okay, put this stone in this little hole!"

"Yes!" The green crocodile hurriedly complied, lifted the end of the stone bar and pushed it into the hole, looking at the green crocodile's relaxed expression, Xiao Nan couldn't help but sigh that this product is really powerful, this is a piece of weight of tens of thousands of catties, this product can be easily loaded into the small hole!

It seems that this stone strip was originally placed in this hole, and after it was put in, the small hole was just filled, and there was no gap on all sides! The stone strip was put into the small hole and did not cause any changes, everything was still the same as it was, Xiao Nan couldn't help but be a little strange, and when he looked closely, the direction in which the stone strip was put in was incorrect, and the texture of one end of the stone strip was obviously inconsistent with the cave wall. Xiao Nan hurriedly asked the green crocodile to pull out the stone bar, carefully observed it himself, and let it adjust the angle and put it into the small hole again.

"Young Master Xiao, come and see the changes here!" The stone bar had just been put into the cave, and Yuan Zhen called out at the eye of the array, his voice full of excitement.

"What change?" Xiao Nan hurriedly came to Yuan Zhen's location and looked at the place where Yuan Zhen's eyes could see. I saw that the lines in this place became clear, and gradually turned into a swirl, converging towards the center of the array!

"Xiao Gongzi, it seems that this is really where the eye of this formation is, it may be that this formation has been exhausted due to its age, so it can't be opened. Yuan Zhen looked at the center of the array and said.

"In other words, that piece of stone is the key to opening this formation, if there is energy, this formation can be opened at this time?" Xiao Nan asked.

"Yes, it's just that such a large teleportation array must use a high-grade spirit stone to activate, according to me, there are not many high-grade spirit stones on this Kunyu Continent, all of them are controlled in the large sect and the inner courtyard of the palace, but it is difficult to get a high-grade spirit stone. Yuan Zhen's face was a little gloomy when he mentioned the top-grade spirit stone, and now he also wanted to find a high-grade spirit stone, so that he could see what power the legendary teleportation array had.
