Under the deep cave entrance is a completely miniature underground world, almost the same as the hollow volcanic world, but it is not the scorching qi waves that fill every inch of the pitch-black space, but the cold and piercing pure yin qi.

The concentration of pure yin qi in the eye of the leylines has almost reached its limit, and it is difficult to walk smoothly even in it, which can be seen from this. Even if his physical body was as strong as Xu Qing, he had to forcibly seal the acupoints of his whole body, and he no longer dared to recklessly absorb the pure yin qi that filled every inch of space.

In the darkness, the palms of the two hands are tightly held together, but I wonder if the hearts are equally interdependent?

Xu Qing struggled slightly, intending to withdraw his palm, and the warm touch almost made it difficult for him to control himself. It's just that his palm is tightly gripped, and the only way to pull it out is to use force suddenly.

"Don't struggle, as long as you don't take the initiative to absorb the pure yin qi, you will be fine, but the Xuan Yin qi is completely different, it will actively burrow into your body. My constitution is special, and once the Xuanyin Qi enters your body, I can immediately channel it into my body. Su Yingxue's delicate and slightly trembling voice sounded in the dark, if it weren't for the dark environment, she probably wouldn't even have the courage to speak at this moment.

Among the sects, she is a well-deserved proud daughter of the sky, how could she have taken the initiative to get close to men like this?

Maybe it was because of Xu Qing's sacrifice to save him, or maybe it was because Xu Qing had taken advantage of him, Su Yingxue suddenly found that she was not very resistant to this intimate act, but her face was still bright red as if she wanted to drip blood.

Xu Qing didn't say anything more, let Su Yingxue take her hand, and gradually moved away from the deep hole.

Although it was pitch black, it had no effect on Xu Qing and Su Yingxue, who wandered aimlessly in this pitch-black world, like homeless lonely ghosts.

During this period, an extremely domineering Xuanyin Qi had penetrated into Xu Qing's body. It's just that before she had time to try to refine it, that Xuanyin Qi had been forcibly absorbed by Su Yingxue, but she didn't have the slightest abnormality.

This made Xu Qing have to sigh at the perversion of his system, Rao is Xu Qing has transformed again, and he still doesn't dare to be casual in the face of Xuanyin's qi, so he can only slowly figure it out. But Su Yingxue had no scruples, and inhaled it directly, still acting like a nobody afterwards.

"Ah, it's actually a wonderful sound stone, such a big piece. Su Yingxue suddenly exclaimed. Then he pulled Xu Qing and ran into the distance, his happy expression was almost the same as when a child got his beloved toy.

The wonderful sound stone, which is jade-colored, has the wonderful use of confusing people's minds, and is especially liked by female cultivators. It's just that the Miaoyin Stone is very rare, and it is only possible to find it in the most yin and cold places.

Su Yingxue gently picked up the crystal clear jade on the ground about the size of two fists, and her cautious appearance seemed to be afraid of breaking it, her crystal clear eyes were full of happy smiles, and her soft face was on her soft face. The smile is as gorgeous as the sunset.

As if she had discovered Xu Qing's gaze, Su Yingxue looked ashamed: "I have always wanted to refine a magic weapon, but unfortunately there has never been the whereabouts of the Miaoyin Stone, and now I have finally found it." ”

Su Yingxue seemed to know very well about refining materials. After the Miaoyin Stone, in the dark underground world, she found a lot of refining materials, and even a lot of treasures. Of course, only the Miaoyin Stone had ever made her smile the brightest.

"There seems to be a lot of Xuanyin Qi ahead, even if they burrow into your body, you don't want to resist it. I'll channel them all into my body at once. Su Yingxue suddenly paused, and her tone was slightly solemn.

Xu Qing looked ahead, and sure enough, he vaguely saw nearly twenty violent Xuanyin Qi wandering around in the air in the distance, like a hungry jackal choosing people to devour. If you don't worry about it at all, it's a lie at all, even if Xu Qingbao is strong, he doesn't dare to argue with the twenty Xuanyin Qi at the same time, just out of trust in Su Yingxue, he didn't turn around and leave in fright.

Su Yingxue didn't say much, but she was very happy in her heart, just so that Xu Qing could believe in her without hesitation. When facing the danger of life and death, how many people can completely surrender their lives to others? Thinking of this, holding Xu Qing's hand, he couldn't help but tighten a little more.

Letting Su Yingxue take her left hand, Xu Qing walked towards the place where the Xuanyin Qi gathered.

In the end, Xu Qing's worried situation did not appear, I don't know what kind of means Su Yingxue used, almost all of the nearly twenty Xuanyin Qi roared into her body, like a cat seeing a mouse. Although there were still a few fish that slipped through the net and burrowed into Xu Qing's body, they were quickly absorbed by Su Yingxue, and they didn't even have time to destroy Xu Qing's body.

Absorbing twenty Xuanyin Qi at one time, even if Su Yingxue's system is extremely special, it is still a little difficult to bear, her breath has obviously become a little scattered, and the palm holding Xu Qing is constantly dripping fine beads of sweat.

"You don't care, do you, quickly channel a part of the Xuanyin Qi into my body, I can bear it. Xu Qing tightened Su Yingxue's soft jade hand, and said in an eager tone.

It's just that Su Yingxue didn't seem to hear it at all, and it wasn't until ten breaths later that she smiled and said, "Now they have been completely subdued." ”

Under Xu Qing's curious gaze, Su Yingxue took out a special white jade bottle, and nearly twenty extremely docile Xuanyin Qi emerged from her fingers in turn, and then drilled into the jade bottle.

Su Yingxue handed the white jade bottle to Xu Qing, and her gentle tone could melt any man in the world: "The Xuanyin Qi seems to be very helpful to you, I have already subdued them, and it should be more convenient to refine." ”

Xu Qing shook his head directly, and rejected Su Yingxue's kindness: "This is something you have worked hard for, how can I ask for it?" And your physique is special, and the Xuanyin Qi is also of great help to you, and a gentleman does not win people's love." ”

In the dark, Su Yingxue's clear eyes and grievances flashed away.

"Then I'll keep half of it, and you can't refuse it anymore. Su Yingxue took out half of the Xuanyin Qi from the white jade bottle, and then handed the white jade bottle to Xu Qing again, looking at the posture, as long as Xu Qing still refused to accept it, she would immediately turn her face.

Xu Qing had no choice but to accept the white jade bottle, and Su Yingxue's face showed a happy look at this time.

Su Yingxue didn't leave there, but churned around the gravel on the ground, as if she was looking for some treasure. Xu Qing was not surprised, although the pure yin qi in the underground world was extremely strong, the Xuanyin qi was rare, and there were nearly twenty Xuanyin qi gathered here, so naturally there would be something extraordinary.

"It's a pity that there is no Xuanyin Stone generated, let's go back, there may be more Xuanyin Qi inside, and it is a little dangerous. Su Yingxue said softly, and then pulled Xu Qing towards the direction where the exit of the underground world was. She was pure-minded, and she was not good at hiding her emotions, and a deep sense of disappointment hung on her face.

Xuanyin Stone was born in the place of Yin to Cold, and there is the Qi of Xuanyin refining day and night, and the cold is like 10,000 years of Xuanice. After refining into a magic weapon, it can not only hurt the body, but also directly hurt the soul, which is difficult to heal. And because the sex is yin and cold, it has a strong restraint effect on the magic weapon of the most rigid and yang attributes.

"It's so kind and heartbreaking. Xu Qing sighed in his heart, according to his guess, Su Yingxue must need the Xuanyin Stone to refine the magic weapon, but he chose to give up because he was concerned about his safety.

Xu Qing gently grabbed Su Yingxue's plain hand, and said as if he was a little embarrassed: "If Miss Su doesn't mind, let's go deeper for a while, if it's really dangerous, it's not too late for us to retreat." This underground world is so magical, wouldn't it be a pity if you didn't enjoy it?, and now those ghost generals may not have left, even if they go back, they can only wait patiently for them to disperse, in this case, it is better to go to the depths to try their chances. ”

In the dark, Su Yingxue's eyes were as bright as starlight, and they seemed to be able to shine directly into the depths of Xu Qing's heart. After a while, the light in her eyes disappeared, and Su Yingxue said softly: "Thank you!"

Xu Qing was slightly stunned, and then said with a wry smile: "Why should Miss Su be so polite, if it weren't for your help, I'm afraid I would have been devoured by ten thousand ghosts." ”

"Do you want to repay the favor?" Su Yingxue murmured softly.

"There is still something down there, I don't know if to talk about it or not?" Xu Qing's face was a little hesitant, not knowing how to talk about it.

"Childe, please speak. Su Yingxue's eyes fluttered, and she looked at Xu Qing curiously.

"Miss Su's mind is pure, there are few in the world, but in the future, you must not trust others so easily, it is difficult to know the face of people, if I have evil intentions in my heart at this moment, Miss Su can't be careful at all. ”

"Thank you for the compliment. Su Yingxue's eyes were obviously a little snickering and shame, and after calming down a little, she smiled and said: "Yingxue is not ignorant of people's sinister hearts, on the contrary, she may see them more thoroughly than ordinary people. ”

"There is such a miraculous ability in the world? Xu Qing suddenly realized in her heart at this time, no wonder Su Yingxue seemed to be unworldly, but her sect was able to rest assured that she would go out to try alone.

"Of course, this ability is not invincible, if the cultivation is high and far-reaching beyond me, then it will be difficult for me to detect his mood. Su Yingxue has not become proud because of her magical talent, and she is still gentle and gentle.

Xu Qing and Su Yingxue walked towards the depths of the underground world again, just to find the Xuanyin Stone.

"Xuanyin Stone, I finally found it. ”

The dark underground world is indistinguishable from day and night, and after being disappointed three times in a row, Su Yingxue finally found the Xuanyin Stone as she wished.

"Damn, either there is no one, or there are four at once. Su Yingxue picked up the four pieces of bluestone, all the size of a fist, and complained dissatisfied, but her expression was very happy.

"Childe may use it in the future, Yingxue only needs two pieces to be enough. Su Yingxue handed the two Xuanyin stones to Xu Qing, and although her tone was weak, she could not refuse. Xu Qing didn't dare to refuse, so he could only accept the two Xuanyin stones.

Although there is a certain danger in going deep into the underground world this time, it is all worth it compared to the gains. On the way to find the Xuanyin Stone, he had a total of more than twenty Xuanyin Qi, and these Xuanyin Qi were enough to make his treasure body go to the next level. (To be continued.) )
