Others didn't know what the hell the Yin and Yang lock was, and Qing Feng could only explain when he saw this: "This lock is actually nothing, I'm just curious why the owner of this cave mansion would choose such a simple lock." ”

Yin and Yang Lock: If the key is placed in the same place, it is nothing, but if one is placed in the north and the other is placed in the south, it will be difficult to open the locked things, even if you want to forcibly destroy it, it will be useless, unless you enter the level of immortals.

Put the two keys into the keyhole respectively, this keyhole is very small and imperceptible, after the key enters, there is no reaction at first, until two minutes have passed, the huge and heavy stone door trembles slightly, and then slowly opens to both sides.

"Those three remnants were stupid enough before, and they died here without finding something so easy to find, and I'm really curious how they died. The fat man smiled and was the first to stride in.

Ning Zixuan followed him, followed by Qingfeng and Liyueran, and the other four were in the back.

The inside of the stone gate was extremely dark, and without the light of the oil lamp, it was impossible to see anything here except for a little glimmer of light, and even if it was investigated with divine sense, it was fruitless.

"I don't know if there is any great inheritance here, or something useful. Qingfeng muttered to himself and walked forward.

"Hahaha, hundreds of years have passed, and someone is finally able to get here!"

A hearty laugh came from afar, then got closer.

"Who?" Ning Zixuan's eyes shot out of a golden light and looked in the direction of the voice.

"Don't be nervous, I am the master of this cave, you have successfully passed my test, then please come with me to the reward you deserve, I will give you a fairy weapon!" The voice came closer, and an old man with gray hair but full of spirit stood in front of them.

Qingfeng's heart was shocked, immortal weapons! That is a treasure that only exists in the fairy world, even in the spirit world, there are very few immortal weapons!

The fat man walked in front, and when he heard that there was a reward brush, he ran over, and Luo Feng was not far behind, and then he ran out like this.

When they came to the old man's side, their bodies stiffened slightly, and then they instantly returned to their nature, because only for this short moment, neither Ning Zixuan nor Qing Feng noticed the slightest abnormality.

"Aren't you coming? The fat man and Luo Feng greeted the six people here, their expressions were no different from before, Qingfeng nodded at Ning Zixuan, and the six of them walked away.

Just as they were about to get closer, Luo Feng and the fat man also took two steps towards this side, and Li Yueran, who had been paying attention to the two of them, blinked his eyes, wanting to look more carefully, and finally frowned tightly.

"Qingfeng, don't you think it's a little strange for the fat man and Luo Feng to take two steps back?" Li Yueran said to Qingfeng on the side.

Listening to her words, Qingfeng also paid attention to the actions of the two, and after a closer look, there was indeed something wrong, very subtle, if it wasn't for Li Yueran telling him, he really couldn't see it.

"It's a bit of a problem, I think they may have been ordered by the old man, or they were evil. ”

Li Yueran's eyes widened, then she looked at Ning Zixuan, and motioned to him, and Qingfeng said to Ning Zixuan: "Zixuan, Luo Feng and the fat man seem to have a problem, be careful, this old man is definitely not the real master of the cave." ”

"Well, I just found out, let's hold our ground and see what happens. ”

Qingfeng looked around for a moment, then asked, "Will you keep the old man's Destruction Formation in the record?"

"Not before, but now it's in the middle of Jindan, you can try, what's wrong? Do you think they're controlled by some monster?"

"Quite possibly, just in case. ”

After saying that, he quietly began to arrange the destruction array, and the formation was formulated without rank, which was a formation that specifically restrained some monsters.

Ning Zixuan did not hesitate, and began to arrange it slowly, but Gongsun Dianwei and Wu Yue and Chen Hao did not know it, and the reason why they did not tell them was that they were afraid that some abnormal behavior would attract the attention of the old man.

After walking for nearly 5 minutes, they continued to walk, and at this time Wu Yue and Chen Hao also found an abnormality, usually this fat man can have so long without changing his face and complaining?

"Zixuan, did you and Qingfeng see something?" Wu Yue said.

Ning Zixuan just nodded, now he can only concentrate on arranging the formation, and there must be no mistakes, otherwise it will fall short.

"What kind of formation is he and Qingfeng arranging, don't disturb them. Li Yueran could only answer for Ning Zixuan, and Wu Yue didn't say much, just looked at the backs of the two people in front of him, which was weird.

The Destruction Array gradually took shape under the arrangement of the two of them, in order to suppress that fluctuation, they could only arrange it little by little, and in the process of this formation slowly taking shape, Qingfeng looked at Ning Zixuan's expression, and decided to restore Luo Feng and the fat man to their senses first.

He quietly quickened his pace and came to the back of the two, and at that moment the old man stopped, then turned his head sharply, and when they thought they had been discovered, the old man actually looked up to the sky and laughed.

"Hahaha, you guys are so foolish, now become a sacrifice for me to reshape my flesh! My two slaves, kill them!" He was very excited at this time, how long has it been!

Qingfeng also did not hesitate to directly slap his palms on the backs of the two, only to hear the "bang" twice, a black gas dispersed from their bodies, the two instantly returned to their previous appearance, the fat man rubbed his head and asked, "What happened just now? Why did my head look like I was smashed by a wooden fish, drowsy." ”

"Me too. Luo Feng was also rubbing his temples.

When the old man saw that his two puppets had been rescued like this, the words he had just released immediately made his face hot, his eyes widened angrily, and he scolded in his heart: "I didn't expect that there would be a guy who can relieve the demonic energy! It seems that this kid is not simple, and he can't be left behind!"

He looked at Qingfeng's smug smile, and his heart burned even more angrily: "Good boy, you dare to play tricks on me!"

Just when he was about to make a move on Qingfeng, he found Ning Zixuan, who had always been silent, he was quiet and terrifying at this time, his eyes were tightly closed, and his mouth was quickly reciting the formation mantra of the Destruction Formation.

The old man suddenly had an ominous premonition in his heart, and his intuition told him that the mantra recited in Ning Zixuan's mouth made him feel palpitations, which also showed that the final formation of this mantra might cause him harm!

"Boy, the old man will leave you floating for a while, and then I'll clean you up later!" The old man directly changed his previous direction and went towards Ning Zixuan.

How could Qingfeng just watch him approach Ning Zixuan? Hurriedly quickened his pace to meet him, the old man's speed was so fast, Qing Wei couldn't keep up with the amazing speed, Gongsun Dianwei and Wu Yue and Chen Hao also moved forward quickly, leaving Li Yueran in place and looking at the two who were a little groggy.

"When..."

Wu Yue's long sword slashed directly at the old man's robe, but it was not the sound of the robe tearing, but a crisp sound, and the long sword seemed to fall on top of steel.

Chen Hao's battle axe also fell directly, just a little spark popped up, but it did not play the slightest role, Gongsun Dianwei's hands were sealed, and a fierce fist wind smashed towards the old man's face, which made the old man frown.

I saw that his left hand lightly held the dragon claw that Qingfeng grabbed at him, and his right hand held a turquoise blue long sword, the sword body of this long sword was one meter and a half long, and it was directly swung towards Wu Yue, Chen Hao and Dian Wei in the back.

Just with a slight wave of his hand, the sword qi was like a rapid slash, but it was affected by the sword qi, and a blood mark appeared on Wu Yue's left hand.

This was the first time he had been injured by a sword, Chen Hao hurriedly supported him, Wu Yue shook his head, and said that he was fine.

Qingfeng looked at the sword and thought, "This should be a primary spiritual weapon!"

While thinking about it, the old man's big hand grabbed at him, and the feeling of oppression made him a little suffocated, this kind of cultivation has at least reached the realm of transforming gods!

As soon as he got the answer, his whole person flew out directly, and there was a sharp pain in his stomach and chest, the old man looked at Ning Zixuan, and in the blink of an eye, he appeared in front of him, and he was about to slap his palm down.

Seeing that Qingfeng turned into a body entrenched in this dark space, the old man's eyelids jumped and stopped the action of slapping, and looked at Qingfeng who turned into a dragon body: "I thought you were practicing some dragon clan exercises, but I didn't think that you were a dragon clan person." ”

Qingfeng didn't say a word, and with a roar, his huge body rushed over, and the old man looked at the rushing Qingfeng and smiled faintly: "Even if you turn into the body, what can you change?" ”

"Look, I'll get rid of this person you want to protect first. After saying that, the old man's stopped hand fell again.

At this moment, a somewhat clear voice came from Ning Zixuan's body: "Hmph, even if you are possessed by a demon, you also want to hurt him?"

The old man's face changed drastically, the strength of the owner of this voice was far superior to him, this was a person from the fairy world!

He suddenly withdrew his hand and wanted to retreat, but he was swept up by a white wave of qi, flew out dozens of meters upside down, spit out a mouthful of black blood and half-knelt on the ground, obviously seriously injured: "Who the hell are you!"

"You are not qualified to know, and perhaps you can ask your Lord, but you have no chance of going back. ”

The old man chuckled in his heart, this man actually knew his master! Could it be that his cultivation had reached the top level of the immortal realm?!

"Old fellow, you're still alive!" Qingfeng was very happy at this time, completely lost the previous vows, but like a child.

"Xiaolong, I haven't seen you for a long time, haha, if it weren't for this kid condensing into a divine consciousness body, I wouldn't have been able to appear in this mental state so quickly, Jin Dan condensed a divine consciousness body, and it was really a good seedling. The voice laughed and hung the old man aside.

Gongsun Dianwei, Wu Yue, Chen Hao, Fatty, Li Yueran, and Luo Feng looked confused, who is this breeze talking to? Also, this voice came from Ning Zixuan's body?
