After the stunned Shen Fei blinked his eyes fiercely for a while, he asked Shen Yanyun with some hesitation:

"Auntie, what should I do?"

"What else can I do, naturally I will refine the ore into low-grade silver and iron, and then you will mix it in this place for a year, and then pay 100,000 catties of low-grade silver and iron to lift the punishment after a year, and you can sell low-grade silver and iron or medium-grade silver and iron in the future, but you must not expose the top grade and the best quality, such a thing has a chance, hide your identity and exchange something good, but most of it can only be used by yourself. ”

"What can this superb silver iron do? I can't even exchange money in a big way, what's the use of getting so much. Looking at the hundreds of millions of catties of ore, Shen Fei muttered very depressedly, now he is short of spirit stones, he originally thought that he could make a lot of money on spirit stones, but he didn't expect that the good goods could not be sold, and he forced himself to stay in this underground mine for a year, which is really a frustration.

Shen Fei knew that what his aunt said was right, but he also understood that the main thing was that he was not strong enough, if he was now a demon of the Mahayana period, even if he took out hundreds of thousands of catties of top-grade silver and iron, who would dare to attack him?

The little turtles were chattering to comfort Shen Fei, and only Zhi Brain jumped out and shouted:

"Master, you can use silver and iron to make warships. ”

However, when he said this, he was directly scoffed, although everyone knew that it was indeed a very good idea to isolate the divine sense scanning like this, and the silver iron that was abnormally hard was used to build a ship, but after this battleship was built, don't think about anchoring in the harbor, because as long as the monks who have come into contact with silver and iron, they can see at a glance what kind of material this battleship is made of. As soon as this news was conveyed, the results can be imagined.

"Fuck, I forced the master to be ruthless, and he directly refined it into a sword embryo and took it out and gave it away. Don't look at it, this silver and iron market is a mess. Shen Fei stomped his foot fiercely.

Of course, this is just angry talk, with so much silver and iron, he wishes that the price of silver and iron is getting higher and higher, where is he willing to drop the price.

However, this is obviously not the time to seek to refine silver and iron, so I still think about how to survive here for a year.

Thinking of this, Shen Fei didn't bother to pay attention to the so many ores in the different dimensional space, and walked directly towards the depths of the mine.

Anyway, Shen Fei drilled the potholes when he saw them, and he didn't know how long he had walked and how many potholes he had passed. I don't know if Lu Dao met a few miners, anyway, he drilled and confused himself.

However, Shen Fei is not worried about getting lost, if he is really going to get lost, he will dig directly up, dig it for a few thousand meters, and he will always be able to return to the ground.

has this kind of idea as a foundation, so Shen Fei wanders around with his mind. I don't know where Lu Dao went, but he actually heard the sound of rumbling water not far away, so he naturally looked for the sound and went for a while. Wearing a pig's head mask, he clearly saw an underground river appear in front of him.

Looking at the traces under his feet and some broken wooden barrels by the river, Shen Fei nodded, there must have been miners in this place, but there is no silver and iron ore here. So the prospecting miners just stopped here and left.

Well, this is a good place to hide and practice, because the old miners won't come here. The new miners won't come, but they are not afraid of being disturbed, and there is fresh water that can be provided for their own use.

But the only pity is that it's too cold here, right? It turns out that the yin qi is blocked by the red jade fan a meter away, and when you come to the vicinity of this underground river, you are actually pressed by the yin qi to the point of approaching an inch.

Shen Fei blinked, curiously put away the red jade fan, this thing will only be exempted from the effect of receiving the extradimensional space, and it will block the yin qi if it is placed in the storage bag and ring.

As soon as the red jade fan disappeared, Shen Fei immediately hit a spirit, and the cold aura directly penetrated from all directions.

Shen Yanyun immediately jumped out and shouted:

"Xiao Fei, what are you doing? Yin Qi entering the body is very difficult to dispel. ”

"Hey, my aunt is fine, after the yin qi enters the body, you can use the Sun Star Gong to expel it, and I just want to try to see if this can increase my cultivation. Shen Fei was already freezing his teeth rattling, but he was still forcibly suppressing the operation of the exercises in his body, and now he was completely relying on the strength of his own flesh to support him.

Shen Yanyun hesitated for a moment before he said:

"Okay, the practice of the exercises is personal, you can try it, if it doesn't work, quickly take out the fire jade fan. ”

Shen Yanyun really didn't know if this kind of cultivation method was feasible, but he vaguely realized that there seemed to be such a cultivation method in his scattered knowledge, and then he thought that there was no need to restrict cultivation, as long as it was suitable, and he was also taking care of himself, and there was also the treasure of the fire jade fan, Shen Fei would not have a problem, so he let Shen Fei carry out such a practice.

"Hmm. Shen Fei nodded, and then deliberately felt those yin qi, and deliberately introduced the yin qi into his body.

Shen Fei didn't know, and Shen Yanyun, who had no body, although his divine consciousness had recovered a little because of absorbing faith, no matter how he recovered, he couldn't compare with the main master, after all, she was just a wisp of divine consciousness, so their two aunts and nephews didn't know where this underground river was, and how those yin qi were different from those yin qi in other places.

As for the little turtle and the intelligent brain detector, I don't know whether to say that they are simple or restricted by rules, anyway, they will only move if they are ordered by Shen Fei, so even if they find something weird, they will not be very prompted, but will take it for granted to watch the excitement on the side.

Shen Fei absorbed the yin qi intently, and this yin qi penetrated into the muscles, feeling that the muscles were slowly changing in the direction of the ice cubes, but the bones were still hot.

Shen Fei's purpose was to turn his bones into ice, and then use the Sun Star Gong to drive the cold away at once, so as to increase his cultivation in this way.

Shen Fei didn't know, with his current cultivation, it was impossible to withstand such a yin qi, even an ordinary foundation building period disciple, when he came to this place, he would be directly frozen, and if he didn't climb out quickly, he would only turn into ice cubes and wait for death. Where would there be such a death-seeking behavior like Shen Fei who wanted to suck the yin qi into his bones.

And the reason why Shen Fei is so strong is naturally related to his body, which is already incredibly strong.

Of course, it was also related to the martial arts cultivation method he obtained when he first entered the Tianyi Sect Scripture Pavilion, but he didn't notice it.

After a lot of effort, when Shen Fei was about to give up, he finally introduced the yin qi into the bone marrow.

This is good, it is completely different from just now, although the muscles are a little stiff, but he can clearly be sure that as long as his heart changes, he can immediately expel this cold qi from the marrow, but now that the yin qi has entered the bone marrow, Shen Fei's face is snow-white in an instant, his body is directly stiff, and the qi in his whole body is directly frozen, but his thinking is a little paused.

Shen Fei could feel that Shen Yanyun, who sensed that something was wrong, was yelling, and the little turtles were also chirping in panic, but Shen Fei couldn't hear their words clearly, and he was a little confused about their existence.

However, Xiao Bai's induction became clear, Shen Fei could clearly feel Xiao Bai's lonely mood, and this mood was accompanied by reluctance and struggle, obviously Xiao Bai was fighting for something.

Thinking that Xiao Bai was alone in the flying sword that was snatched away, but he never went back to pick it up, Shen Fei couldn't help but feel a pain in his heart, and sent a shout to that Xiao Bai's consciousness:

"Xiaobai!"

The confused Xiaobai's consciousness suddenly became invigorated, and Xiaobai's voice clearly came into Shen Fei's ears:

"Master, where are you? Are you here to pick up Xiaobai? Xiaobai is so afraid, that wicked man is refining Xiaobai all the time, Xiaobai is about to hold on, master, come and take Xiaobai away." ”

"Xiaobai, I'm sorry, I'm ...... now Woo...... It's so cold, it's so cold......" Shen Fei's consciousness was a little confused, and at this time, he also regretted that he was so curious about what he was doing, and he actually wanted to increase his cultivation through Yin Qi?

Even if this idea is whimsical, I should only try it at the muscle layer, where can I directly lead the yin qi into the bone marrow!

Just when Shen Fei's mind was about to be completely frozen, Xiao Bai shouted:

"Master!"

Then, Shen Fei's spirits perked up, and then he felt a light in his eyes, a slight warmth on his body, and then he saw a small figure shining with milky white light, the size of a finger, with a pair of wings appear in front of his eyes.

Shen Fei blinked his eyes hard and muttered with difficulty:

"Wow! Am I dazzled or what's wrong? Why did I actually see Xiaobai? Isn't it in the mortal realm?"

"Master, Xiaobai has finally met his master. Master, you must run the exercises quickly, and you must not fall asleep. The little light and shadow shouted anxiously while flying around Shen Fei.

Shen Fei used all his strength to conjure up a dagger and plunged it directly into his thigh, the blood slowly gushed out, and before it could drip down, it became an ice cube.

But just like that, the pain of that moment also made Shen Fei sober up, and then before he could see how Xiaobai suddenly appeared in front of him, Shen Yanyun's anxious voice sounded:

"Xiao Fei, hurry up and run the exercises, hurry up and agree to the flame girl to go out, quickly!"

"Huh?" Before Shen Fei could react to what was going on, he just subconsciously followed his aunt's words, and in an instant, thirty flame girls appeared beside him.

As soon as these flame women came out, they immediately gathered around Shen Fei, and their fiery red hair directly turned into flames and burned, illuminating this dark place at once.

And as their flames lit up, there was a steaming heat all around, and you could see how cold this place was. (To be continued.) )
