No one else knew what the Yin-Yang Lock was. Qingfeng could only explain when he saw this: "This lock is nothing. I'm just curious why the owner of this cave chose such a simple lock."

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

Put the two keys into the key hole respectively. The key hole is extremely small and difficult to detect. After the key enters, it has not reacted at first. Until two minutes have passed, the huge and thick stone door trembled gently, and then slowly opened to both sides.

"The three remnants of souls were stupid enough. They died here without finding something so easy to find. I'm really curious about how they died." The fat man smiled and walked in with big strides.

Ning Zixuan followed him, followed by Qingfeng, Li Yueran, and the other four were at the end.

The stone gate was extremely dark, without the light of the oil lamp, there was no clear view of anything except a little light here, and even the use of spiritual sense to detect it was fruitless.

"I don't know if there is any powerful inheritance or some useful things here." Qingfeng murmured to himself and walked forward.

"Hahaha, hundreds of years have passed, and someone can finally get here!"

A burst of hearty laughter came from a distance and then got closer and closer.

"Who?" A golden light shot out from Ning Zixuan's eyes and looked in the direction of the sound.

"Don't be nervous, I am the master of this cave. You have successfully passed my test. So please come with me and the reward you deserve. I will give you an immortal weapon!" The voice came closer, and a white-haired, but full of energy stood in front of them.

Qingfeng was shocked, the immortal weapon! That is a treasure that is only available in the fairy world. Even in the spiritual world, there are very few immortal weapons!

The fat man walked in front and ran over when he heard the rewards. Luo Feng was unwilling to fall behind. Then the two funny guys ran out like this.

When they arrived at the old man, their bodies stiffened slightly, and then they instantly returned to nature, because in this short moment, Ning Zixuan and Qingfeng did not notice any strangeness.

"Are you not here? Let's go together." Fatty and Luo Feng greeted the six people here, their expressions and expressions were no different from those before. Qingfeng nodded to Ning Zixuan, and the six people then stepped away.

Just as they were about to get close, Luo Feng and Fatty also took two steps towards this side. Li Yueran, who had been paying attention to the two, blinked her eyes, wanted to see more carefully, and finally frowned tightly.

"Qingfeng, don't you think the two steps of Fatty and Luo Feng walking back are a bit strange?" Li Yueran said to Qingfeng on the side.

After hearing her words, Qingfeng also noticed the actions of the two. After careful observation, there was something wrong, very subtle. If Li Yueran hadn't told him, he wouldn't have seen it.

"It's true that there's something wrong. I think they might have been trapped by that old man or become possessed by evil spirits."

Li Yueran opened her eyes wide, then looked at Ning Zixuan and signaled him. Qingfeng then sent a message to Ning Zixuan: "Zixuan, Luo Feng and the fat man seem to have some problems. Be careful, this old man is definitely not the real master of the cave."

"Well, I just discovered it. Let's hold our troops and see what's going on."

Qingfeng observed the surroundings for a while, and then asked, "Can you keep the old man recorded the destruction formation?"

"I didn't know before, but now I'm in the middle of the Golden Pill. You can try it. What's wrong? Do you think they are controlled by some monster?"

"It's very likely, just in case."

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

Ning Zixuan did not hesitate and began to make arrangements slowly. Gongsun Dianwei, Wu Yue and Chen Hao were not aware of it, and the reason was that he was afraid that something abnormal would attract the old man's attention.

After walking for nearly 5 minutes, he continued to walk. At this time, Wu Yue and Chen Hao also discovered something abnormal. How could this fat man have been so long without changing his face and no complaints?

"Zixuan, did you and Qingfeng see something?" Wu Yue said in a voice transmission.

Ning Zixuan just nodded. Now he can only concentrate on setting up the formation. There must be no mistakes, otherwise he will fail.

"What formations are he and Qingfeng setting up, don't disturb them." Li Yueran could only answer for Ning Zixuan, and Wu Yue didn't say much, just looking at the backs of the two people in front, it was weird.

The destruction array gradually formed under the arrangement of the two. In order to suppress the fluctuation, they could only arrange it bit by bit. As the formation slowly formed, Qingfeng looked at Ning Zixuan's expression and decided to restore Luo Feng and the fat man's mind first.

He quietly accelerated his pace and came behind the two of them. At this moment, the old man stopped and turned his head suddenly. When they thought they were discovered, the old man actually laughed to the sky.

"Hahaha, you are so stupid. Now you will become my sacrifice to reshape my body! My two slaves, kill them!" He was very excited at this moment. How long has it been! Finally, he had the chance to go out!

Qingfeng slapped the two of his palms on the back without hesitation. He heard two "bangs" sounds, and a black gas was dissipated from them. The two of them instantly returned to their previous appearance. The fat man rubbed his head and asked, "What happened just now? Why did my head look like it was hit by a wooden fish, and it was dizzy."

"So too." Luo Feng also rubbed his temples.

When the old man saw that his two puppets were rescued, his face suddenly became hot when he released the words. He glared and cursed in his heart: "I didn't expect there would be someone who could relieve the demonic energy! It seems that this kid is not simple, so he can't keep him!"

He looked at Qingfeng's smug smile and felt even more angry: "Good boy, how dare you play tricks on me!"

Just when he was about to attack Qingfeng, he discovered Ning Zixuan who was always silent. At this time, he was so quiet that he was terrible. His eyes were closed tightly and his mouth was quickly reciting the formation formula of the destroying array.

The old man suddenly had an unknown premonition in his heart, and his intuition told him that the mantra he was chanting in his mouth made him feel palpitations, which also showed that the final formation of this mantra might cause harm to him!

"Boy, I will keep you for a while and then deal with you later!" The old man changed his previous direction and headed towards Ning Zixuan.

How could Qingfeng just watch him approach Ning Zixuan? He quickly accelerated his pace and went up. The old man was so fast that he could not keep up with the amazing speed if he was more risky. Gongsun Dianwei and Wu Yue and Chen Hao also moved forward quickly, leaving Li Yueran looking at the somewhat drowsy two people in place.

"Dang..."

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

Chen Hao's battle axe also fell directly, but only sparks appeared, but it did not work at all. Gongsun Dianwei formed seals with both hands, and a fierce fist wind slammed into the old man's face, which made the old man frown.

His left hand was lightly holding the dragon claw that Qingfeng grabbed at him, while his right hand was holding a blue long sword. The sword body of the long sword was 1.5 meters long, and it swung directly to Wu Yue, Chen Hao and Dian Wei behind.

Just with a gentle wave, the sword energy slashed quickly like a trainee. However, it was affected by the sword energy, and a blood mark appeared on Wu Yue's left hand.

This was the first time he was injured by a sword. Chen Hao hurriedly supported him. Wu Yue shook his head and said that he was not seriously injured.

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

As he thought about it, the old man's big hand grabbed him, and the oppression made him feel a little suffocated. His cultivation level was at least at the level of transformation!

As soon as he got the answer, he flew out directly, and a severe pain came from 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 raised his palm and was about to slap it.

I saw that the Qingfeng turned into the body and entrenched in this dark space. The old man's eyelids jumped and stopped the shooting, and looked at the Qingfeng who turned into a dragon body: "I thought you had practiced some dragon clan skills, but I didn't think you were a dragon clan person."

Qingfeng didn't say a word, and his huge body rushed over with a roar. The old man looked at Qingfeng rushing towards him and smiled faintly: "What can be changed even if it turns into its essence? An ant is still an ant, and there will never be a chance to turn over."

"Look, let me solve the person you want to protect first." After saying that, the old man stopped and fell down again.

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

The old man's face changed drastically. The master's strength was far superior to him. This is a person from the fairy world!

He suddenly withdrew his hand and wanted to retreat, but was swept backwards by a white air wave, flying back dozens of meters, spitting out a mouthful of black blood and half kneeling on the ground, obviously seriously injured: "Who are you!"

"You are not qualified to know. Maybe you will know by asking your Lord, but you don't have the chance to go back."

The old man's heart skipped a beat. This man actually knew his master! Could it be that his cultivation has reached the top level in the fairy world?!

"Old guy, you are still alive!" Qingfeng was very happy at this time. He completely lost the kind of swearing he had before, but instead looked like a child.

"Xiaolong, long time no see, haha, if this kid hadn't condensed into a spiritual body, I wouldn't have appeared in this mental state so quickly. The golden elixir would have condensed out of the spiritual body, and it was indeed a good seedling." The voice laughed and left the old man aside.

Gongsun Dianwei, Wu Yue, Chen Hao, Fatty, Li Yueran and Luo Feng were confused. Who did Qingfeng talk to? Also, this voice came from Ning Zixuan's body?
