Yang Chengzhi took a bunch of little guys out of this secret room and came out along the passage when he came, and as soon as he got out of the passage, a few little guys saw Zhang Jinfei sitting on the futon and became honest all of a sudden, and saw that the door was not opened, so he honestly lay in a corner of the room.

Seeing this scene, Yang Chengzhi couldn't help but smile in his heart, these little guys really knew how to look at each other, knowing that Zhang Jinfei's cultivation was superb, and one by one he became honest, you must know that these little guys were not like this when Long Xingtian and others went to Yangjiagou, maybe these little guys felt that Zhang Jinfei had no ill will towards Yang Chengzhi.

Zhang Jinfei couldn't help but be stunned when he saw Yang Chengzhi come out empty-handed, although the things in the secret room were not too precious, but they were all heavy treasures for ordinary cultivators, but this kid had stayed in it for so long and didn't bring anything out, which made Zhang Jinfei feel strange.

He could think that Yang Chengzhi had already put a lot of things that Daxue Xiaoxue saw into the space, if Zhang Jinfei knew it, he didn't know if he would think like this.

Zhang Jinfei got up and pressed a series of numbers on the Nine Palace Plate, the wall slowly closed, and the door of the room also reopened after the wall closed.

Seeing this scene, Yang Chengzhi couldn't help but sigh in his heart at the ingenuity of the craftsman who built this building, but he didn't know if the craftsman who built such a building was still there, if he was, he might have the opportunity to invite this person to Yangjiagou to design such a secret room for himself.

Yang Chengzhi also knew a little about the craftsmen who built this kind of building, and he knew that there was a kind of person who specialized in this kind of activity in the past era, and in the words of the cultivation world, this kind of person was proficient in Qimen Dunjia.

But since he came into contact with cultivation, he has never encountered this kind of cultivator, and legend has it that this kind of cultivator is more difficult to deal with than ordinary cultivators, because you don't know when he set up a mechanism for you earlier.

Zhang Jinfei saw that Yang Chengzhi was distracted, and asked with a smile: "What is the little guy in a daze, do you regret not bringing something out, it's okay to let you go in again when you leave."

Yang Chengzhi shook his head, "Master, it's not that I regret not bringing the things inside, but I sigh that the skilled craftsmen who designed this secret room don't know which master designed these mechanisms for the organization."

Zhang Jinfei laughed out loud after hearing this, and after laughing, Zhang Jinfei asked with a smile: "Do you want to learn the art of Qimen Dunjia?"

Yang Chengzhi smiled, "The disciple's qualifications are dull, I'm afraid I won't be able to learn, I just want to see it", in fact, Yang Chengzhi was moved when he heard Zhang Jinfei's words, but he knew that such cultivators were relatively rare even in the past, not to mention the current era when there were few cultivators.

Zhang Jinfei glanced at Yang Chengzhi and laughed, "The little guy is not careful, if I say that the Yanhuang Iron Brigade was designed by me, do you believe it."

Hearing Zhang Jinfei's words, Yang Chengzhi's face showed shock, and he blurted out: "Master, your old cultivation is the art of Qimen Dunjia."

Zhang Jinfei nodded, and said with a smile: "Why, I can't practice the art of Qimen Dunjia, didn't you listen to Haotian say, we are all a branch of the Yue Tomb, and left a lot of ancient books of the art of Qimen Dunjia for the ancestors who were forbidden under the Yue Tomb, my master was fortunate to learn the art of Qimen Dunjia, I just learned a little fur, if you have the heart, I can teach you."

"Master, I'm afraid that I won't be able to learn and lose your old face." Yang Chengzhi said embarrassedly, but his heart blossomed, if he could get such a powerful guidance, he would definitely have the power to protect himself.

Zhang Jinfei pondered for a while, "This also depends on the chance, some people may not be able to learn it in a lifetime, but some people can get started in a short time, wait for me to talk to you about this Qimen Dunjia first, and then I will give you a few copies of the foundation of Qimen Dunjia, if you can understand it, ask me if you have any questions, if you don't understand, you can return the book to me."

Seeing Zhang Jinfei say this, Yang Chengzhi hurriedly knelt down in front of Zhang Jinfei, and kowtowed respectfully three times, "Thank you for the success of the master, if the disciple can learn something, he will definitely protect the Yanhuang Iron Brigade."

Zhang Jinfei stretched out his hand to help Yang Chengzhi up, and said with a long sigh: "Child, I know that you will be able to achieve something in the future, I hope that when you have enough ability to learn in the future, you can reopen the tomb of Yue, so that the tomb of Yue can see the light of day, this is our greatest wish."

Yang Chengzhi said: "Master, if there is really that day, I will definitely let Yue's tomb reappear in the rivers and lakes and make it a forbidden place that everyone yearns for."

Zhang Jinfei nodded, stretched out his hand and patted Yang Chengzhi on the shoulder a few times, "Come on, child, I'll tell you what this Qimen Dunjia is all about."

After more than three hours, Zhang Jinfei and Yang Chengzhi talked about the origin and development of Qimen Dunjia, and Yang Chengzhi finally understood what was going on with Qimen Dunjia.

Qi Men Dun Jia actually comes from real life, the original Qi Men Dun Jia is a trap set by the ancients for life to prey on prey, and then gradually improved by people before it evolved into the later Qi Men Dun Jia technique.

When the development of Qimen Dunjia reached its peak, Qimen Dunjia also had several branches, the most important of which were traps and formations, like Zhang Jinfei's master who majored in traps back then.

It doesn't mean that Zhang Jinfei's master doesn't understand the formation, you must know that the great power that set the ban for Yue's tomb back then was a formation master, and how could the Qimen Dunjia books he left behind be defective.

After saying this, Zhang Jinfei looked at Yang Chengzhi and asked, "Little guy, how much can you understand what I said?"

Yang Chengzhi smiled, "Master, the disciple is dull, what you just said, I can only understand sixty percent, but I have the confidence to learn this Qimen Dunjia technique."

Zhang Jinfei heard Yang Chengzhi's words, his eyes lit up, his eyes showed heat, and he said in a lost voice: "You said that you can understand sixty percent."

Yang Chengzhi nodded blankly, "Yes, Master, what's the matter, is it not suitable for the disciple to learn this Qimen Dunjia technique."

Zhang Jinfei said excitedly: "You kid, do you know that your ancestor was a genius who cultivated Qimen Dunjia back then, but just this thing, your ancestor could understand forty percent back then, and you could understand sixty percent, which means that you have a relationship with Qimen Dunjia."

Yang Chengzhi heard Zhang Jinfei say this, his eyes widened, he didn't expect that he could understand the six achievements and become a genius, he just thought that he was not suitable for cultivating this Qimen Dunjia technique.

After thinking about it, Yang Chengzhi looked at Zhang Jinfei and asked, "Master, are you saying that I can learn this Qimen Dunjia technique."
