These red crystals are called fire rock crystals, which are precious refining materials, as long as a little bit is mixed into the magic weapon, they can withstand the scorching of the seven fires, and are very popular in the land of no spirits.

In fact, these few pieces of igneous rock crystals are enough for the brother and sister to take them out.

"Boss Hong, did you find any other treasures?" Tong Xiaoye put down the fire rock crystal, and saw that Hong Huangba also picked out a thing with a big fingernail, which looked like a broken porcelain piece, which was also a little unusual, so he asked with anticipation.

"I don't recognize this yet, it's good to look at the material, but it's only such a small piece, it's really hard to distinguish, you dig down and try to see if there are any other fragments." Hong Huangba shook his head, his expression a little solemn.

All that was left was a few middle and lower grade spirit stones, nothing of value, and Tong Xiaoye withdrew from the space in disappointment.

Hong Huangba picked up the broken porcelain piece again and looked at it seriously.

There was still an endless black mist outside, and Ning Yuan's palms were against her back, expelling the evil qi that had soaked into her lungs for her.

The cool spiritual power wandered in her heart, Tong Xiaoye tried her best to mobilize her spiritual power to cooperate, but her dantian was really empty, not only could not help at all, but it made Ning Yuan's spiritual power a little chaotic, Ning Yuan smiled, and said in a low voice: "Xiaoye, you just relax all over." ”

But I was very depressed in my heart, how could I make the little girl quickly enter the fourth layer of the Qi Refining Period? ? He tried to lose his spiritual power to Ono, and although those spiritual powers were sent into the dantian by him, as soon as he left, they automatically merged into the flesh and blood again.

Nine Transformations Rong Yuan Gong is like this, he has been cultivating since he was a child. I know it very well, as long as the tenacity of the physical body is not enough, the dantian will not store spiritual power no matter what.

If his cultivation had been following the strength of his physical body, maybe Ono's Fire Refining Technique would break through the third layer and enter the fourth layer of the Qi Refining Period on its own?

Ning Yuan pondered and sped up the speed of spiritual power transmission.

The evil qi was dispelled, Tong Xiaoye felt much more relaxed, and the coughing sound that had been intermittent finally stopped.

"Brother, you meditate to recover your spiritual power, and I'll continue to open the way." As soon as the evil aura disappeared. Tong Xiaoye immediately regained his vigorous state. Wielding an axe, he slashed at the rock wall.

As far as physical cultivation is concerned, the process of mining is also cultivation, so Ning Yuan did not stop it and set up the Spirit Gathering Array. I quickly entered a state of settling.

Tong Xiaoye is digging hotly. Her strength is growing. He had already far surpassed ordinary third-order martial artists, and he had a hunch that he was not far from entering the third-order realm.

When the time comes, the true qi will be transformed into the true yuan force. The speed of digging spirit stones will definitely speed up by several grades.

She was in a good mood, and she didn't look at the road ahead, but just waved her axe and walked forward, and when she reached a certain place, she suddenly couldn't cut anything.

The black fog was thick, and she couldn't see what was going on, so she had to wake up Ning Yuan.

Ning Yuan's spiritual sense swept at will, and saw that the rock wall in front of him was no different from ordinary except for the color, so he used the green vine technique to break it, and tried several times, but it was unsuccessful.

Mu Ketu, the green vine technique is invincible against the rock wall, it used to take only a moment of effort, but this time it has been so long, isn't it a rock ahead?

Ning Yuan stopped his movements and looked at it carefully with his spiritual sense.

Tong Xiaoye also leaned in, illuminated with a night pearl, and carefully observed the rock wall in front of him.

Unlike the usual black rock walls of the Black Cave, the rocks here were dark brown, like old rust, and Tong Xiaoye tried to scratch them with an axe, but he didn't even leave a trace.

"Brother, this thing is so hard, isn't it a good material for refining?" Tong Xiaoye's eyes lit up, thinking that he had found some kind of treasure against the sky.

She followed Hu Bugui refining, and saw a lot of precious materials, this rock wall can't even leave traces of the best magic weapons, if it is used as refining materials, can it make a higher-level treasure weapon?

Thinking like this, Tong Xiaoye's breathing couldn't help but be a little short.

Being so close, Ning Yuan naturally discovered his sister's excitement and said with a smile: "No matter how good the material is, what's the use of not getting it?" ”

He said that several golden rays of light emitted from the palm of his hand, and the rock breaking technique slashed down on the rock wall like a sharp sword, but it only left a few scratches inch deep, and it was impossible to get it down.

"Huh?" Ning Yuan's eyes condensed slightly, and for the first time, he solemnly buckled his palms, and used five successful forces to show his best ice blade technique.

The ice blade was swift and sharp, indestructible everywhere it went, and the originally solid rock wall finally loosened a little, Ning Yuan increased his strength, and finally cut down a small piece of brown rock wall.

The cave was so dark that Tong Xiaoye didn't bother to take a closer look, followed behind Ning Yuan, and put the fragments into the excavator with the sand and gravel.

The Ice Blade Technique emitted a dazzling white light, which was even more conspicuous in the darkness, and the Dao Ice Blade pierced into the rock wall like a storm, except for the brown rock that was difficult to gnaw, the large rock wall nearby easily slid down, and Ning Yuan stood beside her afar, without even waving his arm a few times.

Tong Xiaoye looked at it stupidly, remembering that he could only dig with an axe like a little mouse, and all kinds of envy and jealousy arose.

Thinking about the Dao cultivation that she had been stagnant in the third layer of the Qi Refining Period, she couldn't even perform a dust removal technique so far, she was suddenly ashamed of herself, and she didn't want to see Ning Yuan acting handsome at all, so she found a place to meditate and cultivate by herself.

Ning Yuan was busy for five days before he cleaned up the rock wall less than half a meter thick, and the rock wall behind it was restored to its previous material, making it easier to deal with, and he saw that his sister was serious about cultivation, so he didn't bother, cast a spell and continued to dig underground.

The spells in the foundation building period are extremely powerful, digging ordinary rock walls is like destroying the withered and decaying, and after a month's effort, Ning Yuan dug out a trace of pale black flames, which is exactly the Wuli Fire that Tong Xiaoye is trying to find.

So he arranged the formation and woke up the little girl who had been practicing with her eyes closed.

Tong Xiaoye was stimulated by Ning Yuan once, this time she was very involved in cultivation, and she forgot to eat when she forgot about time, and when Ning Yuan woke her up, she was still a little dizzy, and her eyes widened and looked at the darkness blankly.

The little girl seemed to have just woken up, her big black eyes were wet. Ning Yuan remembered the scene when she fell asleep as soon as she cultivated when she was a child, and the corners of her mouth couldn't help but curve slightly: "Xiao Ye, you are about to enter the fourth layer of the Qi Refining Period?" ”

"Really, brother, how do you see that?" Tong Xiaoye was overjoyed, and the confusion that he had just woken up was swept away, and he jumped up immediately.

"You haven't eaten for more than a month, and being able to hold on for so long means that there is more and more spiritual power accumulated in your body, which can meet your daily needs, and you have reached the fourth layer. You can completely open up the valley. ”

Ning Yuan's voice just fell. Tong Xiaoye heard his stomach growling.

Her face turned red all at once.

Say what can you say about the valley, it's because the cultivation is too slow to forget to eat!

The black cave was full of black mist, and it was inconvenient to make food, so Ning Yuan baked a few sweet potatoes and cakes for her. And the jerky that I brought in before. Tong Xiaoye was hungry. It was very sweet to grab and eat.

When she saw the faint flame in the depths of the earth, she was in a better mood.

After eating, all the sand and gravel in the cave are put into the excavator. She began the painful path of Earth Fire Refining Body again.

The brother and sister were both concentrating on cultivation, and in the silence, Hong Huangba scratched the wall in the excavator several times, and even deliberately wasted a lot of spirit stones, but the girl never came in to take a look.

This little girl can't wait to come in every time in the past to see if she has dug up the treasure, this time she got such a weird thing, but she didn't come in to take a look, is it already in danger?

It's a pity that he is not good at refining weapons, this Yao Mantis boxing glove was snatched by him, leaving only a trace of divine thought inside the boxing glove, and when the spiritual power is sufficient, he can sense the situation outside, but he can't go out to communicate with the little girl at all.

Now he can only sense that the little girl's brother and sister are still alive, and he doesn't know anything else.

But the things dug up are getting weirder and weirder, the Black Devil Cave is not a place to stay for a long time, if these two guys continue to dig without knowing the depth, I'm afraid they won't even have a chance to leave alive.

It doesn't matter if these two guys die, wouldn't the Yao Mantis gloves be buried deep underground, and their pets will never see the sky.

Hong Huangba regretted choosing Tong Xiaoye as the inheritor for the first time, he knew that it would be good to choose the old man who could choose another boxing, but the old man had some power, although he didn't have much life, at least he wouldn't throw the baby in this dark mine.

But it's useless for him to regret it now, and only by waiting for Tong Xiaoye to die can he find a chance to confess his lord again.

Tong Xiaoye naturally didn't know Hong Huangba's plans, she buried herself in cultivating the fire refining technique, and under the scorching day after day, she had already forgotten the time, and before she knew it, Wulihuo had already finished refining her limbs, leaving only her chest cavity.

The peculiarity of the Fire Refining Technique is that when refining the body in the first layer, it only needs to refine the outer layer of skin, flesh and bones, and the second layer does not involve important organs, but the third layer is more profound.

When the time comes to the Seven Absolute Flames, the flames are to refine the entire body, including the head.

As a modern person, Tong Xiaoye really didn't dare to make such an attempt.

As long as you are alive, you can use spiritual power to regenerate the severed limbs, but the heart is all melted, where is the life to do the follow-up restoration work?

She was in a daze for a long time in the Spirit Gathering Array, and finally woke up her brother.

Ning Yuan listened to the little girl tell about the panic in his heart, and was inexplicably a little distressed, and when Tong Xiaoye finished speaking, he touched the tips of her hair lovingly, and his voice became softer and softer, "Xiao Ye, the road to cultivation is extremely difficult, many monks with unqualified qualifications will usher in the heavenly tribulation when they tie the pill, and the heavenly tribulation will split the physical body to pieces, as long as the divine soul is not extinguished, the physical body can be reshaped, and those injuries are not a problem at all." ”

He had seen Tong Xiaoye practice the fire refining technique, such a magical healing speed, the best exercises he had ever seen were incomparable, it must be a top-level exercise, and it should not be a problem to repair the injury.

But thinking of my sister's first experience of such a process, I was still a little uneasy, "You first slowly lead the five fires to your body, smelt your heart little by little, I will be by your side, once there is an accident, you call me, I will use spiritual power to help you in time." ”

With her brother guarding her, Tong Xiaoye felt much more relieved, slowly drew the flames to her body, and began the smelting process she had done countless times.

In fact, it was very easy to get used to it, smelting little by little, the melted flesh and blood were regenerated in an instant, there was no problem she was worried about at all, Tong Xiaoye quickly entered the state, and until the cultivation was completed, she did not disturb Ning Yuan once.

When it was done, she let out a long breath and couldn't help but hug her brother and turn around several times.

A smile also appeared on Ning Yuan's face that had been tense.

The excited two didn't realize that less than a hundred meters away from them, the magma was surging, and a black aura was slowly spreading upward. (To be continued......) R1292
