After the purple mist dissipated, a three-zhang high white jade gate was revealed. At this moment, the door has opened a gap on its own. In the right corner of the gate, there is a deep hole with the thickness of a bowl, faintly exuding a dangerous smell.

"Hmph, watchdog?" Zhou Nan angrily put away the sect master's order, kicked open the door, and walked in directly.

Behind the white jade gate, there is a passage that is less than ten feet away. At the end of the passage, a blue light curtain hangs.

Walking over, Zhou Nan was not polite, his shoulder shook suddenly, and the blue light curtain was broken and disappeared. But as soon as he entered, a strong sense of intoxication appeared on Zhou Nan's face. It is true that the hall behind the light curtain is exuding an intoxicating medicinal fragrance.

This is a hall of more than 100 zhang in size, and the whole body is shrouded in a hemispherical blue light shield. Around the hall, there are more than a dozen tall shelves, and on each shelf, there are many bottles and cans. Look at the number of them, whether they are thousands or hundreds.

In the middle of the hall, there stood a three-story and ten-zhang high fiery red strange danding. At this moment, below the Danding, a three-zhang huge magic circle was constantly spitting out flames with extremely high temperatures. And the medicinal fragrance is wafting out from the Danding.

In addition, in one corner of the hall, there is a white jade bed with nothing. At this moment, the owner of the bed was sitting cross-legged in front of the Danding, his hands dancing like butterflies wearing flowers, playing a series of tricks, intertwined and submerged into the Danding.

The man was a woman dressed in white, with a thumb-thin golden chain on her limbs and neck. The ends of the chains are connected to several bronze pillars in the corners of the hall. It looks very sturdy. The woman is covered with a white veil and can't see clearly.

Zhou Nan knows. This woman should be the famous sect master of the Dan Sect, and there is no doubt about the Dan Sacred Heart. That veil is peculiar. It was able to isolate the divine thoughts, and it couldn't be detected at all. Of course, Zhou Nan didn't spy on other people's thoughts, just waited quietly.

At this moment, the Dan Sacred Heart is obviously at the critical juncture of alchemy. But because the cultivation has been limited to the foundation building period, the mana is obviously gone. The whole body exudes a faint smell of sweat, like ambergris, although it is rich, but it never gets tired of smelling.

In all fairness. The Dan Sacred Heart, which focuses on alchemy, is really beautiful. The small jasper-shaped body, although you can only see a back, is still very attractive. This is a woman who hides herself behind a veil and intellect, exuding full seduction.

In order not to affect the alchemy of the Dan Sacred Heart, Zhou Nan did not disturb her for the time being, but just stayed quietly. But after half a cup of tea, he frowned. Because the Dan furnace at this moment was 'buzzing' and trembling. Looking at the appearance, it is obvious that the alchemy is going to fail.

In order to refine this furnace of elixir, Dan Sacred Heart did not give up, and gritted his teeth. actually gave birth to the idea of squeezing the true yuan.

This move of Dan Sacred Heart happened to fall in Zhou Nan's eyes. Shaking his head helplessly, Zhou Nan flicked his fingers. A pillar of blue and silver light suddenly sank into the body of Dan Sacred Heart. Suddenly. It was visible to the naked eye that the aura of the Dan Sacred Heart had become stronger.

Got the help of Zhou Nan. Dan Sacred Heart breathed a sigh of relief. The magic trick in his hand changed rapidly, and after a while, he threw a golden spirit grass into the alchemy furnace for a long time, but when he heard a 'bang', the lid of the Dan furnace flew up, and something flew out.

Seeing this, Dan Shengxin looked shocked, and with a wave of his slender jade hand, a colorful glow flew out, and he wanted to grab the pill. But unfortunately, the moment she started, Zhou Nan grabbed the pill in her hand. And the Caixia that flew out also pounced and dissipated directly.

Glancing at Dan Sacred Heart, who didn't do it again, Zhou Nan lowered his head.

At this moment, a dark gold elixir was in his hand, struggling violently. Wrinkled his nose and smiled softly. As soon as the corners of Zhou Nan's mouth curled, a hint of sarcasm appeared.

"Hmph, I can't imagine that the dignified Dan Sect Sect Leader Dan Sacred Heart has actually learned the trick of refining the antidote to poison!"

Hearing this, Dan Shengxin's eyes darkened, and he immediately fell silent. Zhou Nan was right, after refining the medicine many times, she saved some medicinal materials. Unexpectedly, as soon as the detoxification pill was refined, it fell into the hands of Zhou Nan. She knew the consequences, but she didn't regret it.

"I didn't expect it to be Zhou Daoyou, you are here, I don't know how to deal with the concubine?" Dan Shengxin said with a flash in his eyes. Looking at Zhou Nan's expression, it was weird, and it was indescribably complicated. If it was Zhou Nan, she wouldn't be afraid.

"Oh, you actually know me?" Zhou Nan frowned, as if he didn't remember how he had ever seen this woman.

"I don't know Brother Zhou, do you remember the Corpse King Flower?" Dan Sacred Heart was silent, but after a long time, he asked like this.

Hearing this, Zhou Nan's expression was abrupt, and after glancing at Dan Sacred Heart, his eyes suddenly became strange. If he remembered correctly, the same two figures, the same habit of covering their faces, spanning nearly two hundred years of memory, unexpectedly coincided strangely.

"Are you Zou Daoyou?" This time, Zhou Nan was silent. After a long time, he said with some uncertainty.

"It seems that Brother Zhou still remembers the concubine. Yes, I am a monk surnamed Zou. But when we met again, we were still in prison. Zhou Daoyou is here, I don't know what to do?" Dan Shengxin lowered his head, and didn't seem to want to greet Zhou Nan.

"Tsk, it's really a trick to make people! However, I still don't understand a little, as the Immortal Hall Dan Sect Master, why did he take the risk of sneaking into our Xuanhuo Sect's law enforcement prison back then?" Zhou Nan took out a futon and sat opposite the Dan Sacred Heart.

"For the elixir in your hand. Dan Sacred Heart's answer was very simple, but Zhou Nan was dumbfounded and puzzled for a while.

"For this elixir?" Zhou Nan's brows tightened unconsciously, although this elixir was full of spirituality, it didn't seem to be

"Don't be surprised, it's just a half-finished product. The Corpse King Flower is the main medicine for refining this Dan, and there is no underground in the Dan Sect. I have lurked in many second-rate sects, but I have never found them, and the Xuanhuo Sect is my last stop. If it really doesn't work, you can only go to the Kaiyang Sect and the Corpse Puppet Sect to try your luck. But that's dangerous. It's really not a wise move unless it is absolutely necessary. Dan Shengxin's beautiful eyes flashed slightly. Speak quietly.

"I see, no wonder I always thought you were a little strange back then. Zhou Nan nodded. The doubts in my heart will inevitably disappear.

"Is it strange about my appearance, or strange about my behavior?" Dan Sacred Heart raised his head, and his eyes sparkled.

"Both are weird. After all, if the Xuanhuo Sect wants to detain prisoners, how can you let you cover your face with a mask and not be allowed to check it? Recalling the past scene, Zhou Nan suddenly felt quite interesting.

"I didn't expect you to be so cautious. It's been less than 200 years. You have been able to cultivate from the Enlightenment Period to the Late Stage of the Formation of the Dan, such a talent, I am not good at other places, but in the Yan Kingdom, in the past thousand years, you are the first person. Dan Shengxin pursed his lips and said inexplicably. It seems to be envious, like admiration.

"Hey, thanks for the compliment. If you don't mind, though. Can you say your name, or take off your veil?"

"I didn't expect you to be quite careful, my surname is Zou, and the pronunciation of your surname is very close. Well, it's called Zou Ying'er. As for the veil, it cannot be taken off. I swore by it. In this life, you only show what you like, you are not him. Dan Sacred Heart replied. It's unusually innocent.

"Zou Ying'er? Yes, it's a good name. It goes well with you. Zhou Nan muttered a few words and nodded in praise.

"Thank you. Having said all that, you can say your purpose!" Dan Sacred Heart decided not to talk nonsense with Zhou Nan anymore.

"The purpose of my coming to you is very simple, that is, alchemy. However, I am different from ordinary people, as long as you can prove your worth, I can make the decision to fulfill some of your wishes. Zhou Nan smiled slightly, did not hide it, and explained his intention happily.

"If I can meet your request, can you let me out?" Dan Sacred Heart's eyes flashed, and he asked weakly.

"Sorry, I can't. After all, you are also an ancestor of the Yuan Infant Period, although you are not good at fighting, but if you get out of control, it will be tantamount to a big disaster for Xuanlou. We're not afraid of you, but we don't want to get into trouble either. Zhou Nan shook his head, the matter of principle cannot be discussed.

"I see. I promise you, though. Dan Shengxin's expression was gloomy, as if he had already guessed such an outcome.

"Wise choice. Since you gave me alchemy, it was naturally impossible to stay here. You pack up and we'll go out later. Zhou Nan's face was happy, it is convenient for smart people to speak. Of course, before going out, some forbidden measures are naturally inevitable.

Hearing this, Dan Shengxin's eyes flashed, and he glanced at Zhou Nan deeply, then stood up and quickly cleaned up.

After half a cup of tea, seeing that Dan Shengxin was cleaned up, Zhou Nan stretched out his hand a little, and a ray of blood flew into the woman's body, and disappeared strangely.

Suddenly, Dan Shengxin's face changed, and he found that he was completely imprisoned.

It stimulated the power of the ban and sealed the Dan Sacred Heart. With a wave of Zhou Nan's hand, the Linie True Phoenix Sword jumped out. Then with a soft groan, he took the Dan Sacred Heart and the golden chain into it. With the urging of Zhou Nan's method, there was a 'hum', and it disappeared.

In order to take away Dan Sacred Heart, Zhou Nan didn't pay attention to those annoying prohibitions. Directly used the Void Transformation Divine Power to forcibly strip Dan Sacred Heart from the shackles of the golden chains. After a breath, Zhou Nan immediately collected the magic formula, and the Dan Sacred Heart was released.

"Let's go!" Dan Sacred Heart's elixir, Zhou Nan didn't return it, took out a jade box, and put it away properly.

Seeing Zhou Nan turn around and leave, Dan Shengxin blinked with a complicated expression, he really couldn't imagine that he would leave this place one day. Although she had also thought about lifting the ban and escaping before. But happiness came so easily that she was in a trance.

The process of Zhou Nan taking Dan Sacred Heart was very simple, as simple as when he came in. There is a suzerain's order to open the way in front, and all the prohibitions are not a problem. As for the monsters in the black fog, the guards guarding the entrance of the cave, with Zhou Nan's domineering, do they still need to explain?

Half an hour later, when Dan Sacred Heart came to the door of Zhounan's cave, he looked at the blue sky outside, the mountains full of flowers and trees, smelled the faint fragrance of flowers, and touched the soft peaks. I just feel that life is so beautiful, and she can't imagine it.

"Okay, don't look at it, there will be time to appreciate it later. Your value should be contributed to those who have made a difference, as for those mediocre talents, they are just wasting resources if they take a room of pills. A moment later, Zhou Nan poured cold water on Dan Sacred Heart.

"Looks like you're confident. Dan Sacred Heart turned his head, he used to think that Zhou Nan was domineering, but now he has gone to the next level.

"Of course. Far from it, only I and only I have the power to take you out of the dark underground. In exchange for half a freedom, you'll have to work hard. Zhou Nan admitted that he was very cheerful, and there was no discomfort in the slightest.

Dan Shengxin didn't speak, just silently lowered his head and listened quietly, his expression was particularly complicated (to be continued......
