Ten Thousand Years of Yin and Evil are extremely rare things in the cultivation realm, although this thing is not a good thing. However, for demon cultivators, demon cultivators, or those evil cultivators, the Ten Thousand Years of Yin Evil is a rare treasure. If the Yin Qi they found in Xue Xi was more than 10,000 years old, then it would be a big gain. With Xue Xi's means, it is completely possible to refine a spiritual weapon, and even a quasi-immortal weapon is unknown. However, in this kind of place, there will generally be the best elixir, and the elixir of the Yin surname is rare.

Of course, these are not the first reasons for Xue Xi to go there, it is true that those possible elixirs are also a temptation for Xue Xi. But the most important thing is that it is the closest to Karen City, and whoever makes Xue Xitian's surname is a lazy person. Of course, it's better to save some trouble. Xue Xi and Bai Xuan flew for most of the day, and finally came to a valley away. This valley looks no different from an ordinary valley, but who would have imagined that there is a sinister aura that can kill people under this ordinary valley. "Hehe, I really don't see that it can be so beautiful in the yin and evil atmosphere. Bai Xuan looked at the flowers blooming in the valley and everything was magnificent, and his mouth couldn't help but be amazed. Although Xue Xi didn't say anything, her face was also surprised and curious.

"All things are mutually reinforcing, and since they exist, they must have a reason for their existence. We are just two little ants struggling to move up the vast sky. The Heavenly Dao is vast and vain, and even a saint cannot fully comprehend the existence of the Heavenly Dao. Xue Xi said with a little sigh and a sigh. Cultivators fight for their lives with the heavens, and although they are powerful and have a long life, relatively speaking, they have also embarked on a path from which there is no turning back. The end of this path is either death or success, and there is no other choice. Xue Xi has walked on this road twice, but the road ahead is still foggy. It's no wonder that Bai Xuan's words made Xue Xi feel so emotional.

Bai Xuan gently hugged Xue Xi's shoulder, Xue Xi looked back at Bai Xuan, and pulled the corner of her mouth to reveal a smile. "It's okay, I'm just a little emotional. Xue Xifu moved her gaze to the valley again, "Xuan, let's go." Maybe we'll have a big deal this time. Xue Xi didn't say it casually, she had a feeling that she could get a chance here. As for what it is, Xue Xi doesn't know now. Bai Xuan nodded, recovered and summoned the Spear of Destruction, and entered the valley first.

Out of caution, Xue Xi also held the thin willow sword tightly in his hand. Xue Xi was half a step behind Bai Xuan, followed Bai Xuan closely, and also entered the valley. The valley is surrounded by several hills that are not tall, and the layers of those hills are intertwined to form a formation. Xue Xi is a well-deserved array everyone, and it can be seen at a glance that it is a natural Yin Gathering Array. "It's no wonder that such a peculiar yin valley has formed here, and it seems to be inseparable from this great array. Seeing Xue Xi staring at those hills, Bai Xuan didn't dare to slack off, and immediately guarded Xue Xi's side. About two cups of tea, Xue Xi sighed softly. She finally figured out the role of this natural formation. "How's it going? See what's going on, girl. Bai Xuan asked as he pestled the Broken Spear on the ground and leaned on the barrel of the Spear.

"This is a Yin Gathering Array, you should know that. Bai Xuan's lazy appearance made Xue Xi feel very powerless. Bai Xuan raised her eyebrows, "Niu'er, are you underestimating your sister too much?" Although most of my sister's things are obtained from you, my sister is also an eighth-level array master. Bai Xuan's face was full of threat, and Xue Xi couldn't help but roll her eyes. "I know you're an eighth-level array master. However, this formation does have some doorways. You see, the hill that left the position and the hill where the position was in place and the hill where the position was exchanged, these three hills forcibly changed a good yin gathering array into a yang swallowing yin gathering array. Otherwise, this valley has long been cloudy and dilapidated. How can it be like now, a hundred flowers are blooming, and the grass is delicious. ”

After Xue Xi explained a little, Bai Xuan also understood. The Great Array of Swallowing Yang and Gathering Yin actually gathers not only the yin and evil qi, but also the pure yang qi. However, due to the imbalance of this yin and yang division, the amount of yin and evil qi gathered far exceeded the number of pure yang qi. The yin and evil qi sinks below the ground, and the pure yang qi occupies above the ground, so this unique landform is formed. The power of nature is truly bizarre and wonderful. Xue Xi and Bai Xuan couldn't help but sigh at this, the Tao is natural, and it is reasonable in ancient times.

"Let's go, Xuan, let's go down. "If you want to say beautiful, Xuexi's infinite space is more beautiful than here, I don't know how many times. Xue Xi and Bai Xuan didn't have much interest in this scene, they cared about the huge cave underground. The sinister aura had been deposited for an unknown number of years, and it had already corroded the ground into a huge cavern. Xue Xi and Bai Xuan performed the Earth Movement Technique and easily dived into the cave. As soon as she arrived at the cave, Xue Xi felt a chill all over her body. The Chaos Celestial Scripture moved unintentionally, and the chill quickly disappeared. "It is worthy of condensing tens of thousands of years of evil spirit. Xue Xi couldn't help but sigh. "Niu'er, you've suffered a loss. Bai Xuan looked like he was watching a good show.

"Cut, isn't it the same with Xuan. Xue Xi mercilessly exposed Bai Xuan's hypocrisy. Because of Bai Xuan's carelessness, he also suffered a dark loss like Xue Xi. However, she dissolved the yin qi that entered her body earlier than Xue Xi. The sinister aura in the cave has been condensed for tens of thousands of years, forming a thick mist. Rao couldn't see through the fog with Xuexi's eyesight, which made Xuexi frown a little. The so-called unknown is the most terrifying, and Xue Xi also knows whether there will be dangers hidden in the fog that she can't resist. "Niu'er, what is there to worry about. My sister is a monk in the Tribulation Period, and unless there are two masters of the Mahayana Period, it is not easy to save your life. Bai Xuan pinched Xue Xi's face, "Besides, if you really have a good one, my sister will kill the other party and give you martyrdom." Xue Xi waved her hand and slapped Bai Xuan's palm, feeling strange in her heart, is Xuan taking revenge on me?

"Forget it, Miss Ben has a lot of them, so I don't care about you. Xue Xi glared at Bai Xuan fiercely, and then asked calmly, "Alone or together?" "Of course, they acted together." Bai Xuan replied as a matter of course, "Otherwise, how can I protect you, my dear girl." "Then go, my dear Xuan. Xue Xi deliberately bit the words dear very hard, how to listen to it and feel resentful. Bai Xuan hooked the corners of her mouth, revealing an evil smile, not knowing what she was thinking. Xue Xi, who was walking forward, suddenly shivered, and looked around in confusion, but found no enemies. Although Xue Xi was puzzled, she could only shake her head.

Bai Xuan followed, and walked to Xue Xi's side in three or two steps. Although Bai Xuan is not very serious, she will not forget the oath to protect Xuexi. Xue Xi looked at Bai Xuan's position, and a different look flashed in her eyes. Bai Xuan held a gun in one hand, and he was half a step past Xuexi. In this position, Bai Xuan could stop Xue Xi at the first moment of danger. It would be nice if Xuan was a boy. Xue Xi was slightly stunned, and knocked her head hard, damn it, I'm thinking about something. Bai Xuan suddenly heard the wind behind him, and thought that something was sneaking up. When he turned around, he found that Xue Xi was knocking on his head. "Niu'er, are you stupid?" Bai Xuan reached out and grabbed Xue Xi's fist that was about to fall. "Ahh Perhaps under the influence of that charming thought just now, Xue Xi now saw a blush on Bai Xuan's face inexplicably. "I'm just remembering something. Okay now, it's okay. Really. Xue Xi broke free from Bai Xuan's grip and hurriedly covered up her weakness. Bai Xuan looked at Xue Xi's back as she left quickly, feeling a little inexplicable. However, since Xue Xi was reluctant to say it, then she Bai Xuan had no way to type out half a word.

"Ahh Bai Xuan was shocked in her heart, could it be that Niu'er was in danger? Damn, she said that she would protect her, how could she be in danger. Bai Xuan thought as he shot into the mist at great speed. There was a figure squatting on the ground in front of him, looking like Xue Xi. Could it be that Niu'er is injured? Bai Xuan couldn't help but panic a little more, and her feet unconsciously sped up a lot. It's just that what makes Bai Xuan cry and laugh is that where is Xue Xi injured, she is digging on the ground with a happy face. "Xuan, come and help. Xue Xi exclaimed without looking back, "There are so many nether grasses." With this Nether Grass, I can refine the Six Yin Pill. Bai Xuan secretly breathed a sigh of relief, looking at Xue Xi's excited smile, she inadvertently showed a charming smile.

There are many treasures in Xuexi's infinite space, but there are not too many heavenly and earthly treasures of this Yin surname. There are at least 100,000 nether grasses in this area, and the years are basically more than 500 years old, and the best ones even have tens of thousands of years of accumulation. Xue Xi and Bai Xuan spent two days transplanting all of this Nether Grass into the Infinite Space. Xue Xi took great pains to let these Nether Grasses continue to grow. Not only did he find a place where he couldn't get sunlight all year round, but he also laid out a tenth-level Yin Gathering Array. I don't know how many times better the Yin Gathering Great Array is better than the Yin Gathering Great Array, but the Yin Qi in that place in a short period of time can't be compared to this underground cave. After all, the Yin Qi of this underground cave has existed for tens of thousands of years, and the Yin Gathering Great Array has just been arranged.

After discovering the Nether Grass, Xue Xi's expectations for this underground cave were even higher. The black-gray thick fog on the front and back and left seemed to become beautiful in Xue Xi's eyes. As soon as this idea came up, Xue Xi felt extremely stunned. Bai Xuan looked at Xue Xi's face suddenly became entangled, and suddenly recovered, and shook his head speechlessly. This is not the first time she has seen Xue Xi look like this, and Bai Xuan is almost immune. Xue Xi coughed twice and suppressed the strange thoughts in her heart. "Xuan, let's move on. I'm going to see what else I can expect here. Xue Xi said with a smile.

Bai Xuan was noncommittal, but summoned the Shattered Spear out with a thought. "Niu'er, where are we going?" Bai Xuan looked around, shrugged his shoulders and said helplessly, "Anyway, everything looks the same here, we won't get lost, right?" "You are a monk in the Tribulation Period, and I am a top-level Array Dao Master." Xue Xi stretched out her finger and pointed at Bai Xuan, then at herself, and finally pointed at the surrounding fog, and said in a contemptuous tone, "Don't say it's the fog formed by this yin qi, it's not that simple for the Ancient Great Array and the Liangyi Dust Array to trap us." Bai Xuan muttered to himself in his heart, it seems that you know the Liangyi Dust Array very well. "That's right. Bai Xuan thought for a moment, "Then let's go." Bai Xuan raised his foot and was about to walk forward, when he suddenly retracted his outstretched left foot. "Which direction are we going?" Xue Xi unfolded her immortal sense and carefully sensed it for a while, then stretched out her hand and pointed in a certain direction and said, "Let's go there." The yin aura over there is getting stronger and stronger, and if you want to come there, it is the center. Let's go to the center of the cave and we won't be disappointed. After Xue Xi finished speaking, she looked at Bai Xuan, Bai Xuan also nodded gently, and the two no longer hesitated, and disappeared into the endless fog one after another.

Two chapters first, and two more in the evening. In the past, when the leaves fell home, they would sleep lazily and say, and they resolutely didn't get up after ten o'clock. Sleepy, the fallen leaves go to make up for sleep first, and continue to work hard in the afternoon. Yo Xi, one is enough to show.
