Lei Xingfeng couldn't figure out why Xing Feng was like this, but this was good news for him, not an unlucky thing, even if Xing Feng was delirious this time, he also taught him a lot of useful cultivation knowledge, for which Lei Xingfeng was still grateful.

Xing Feng opened his secret door and entered a new continent with Lei Xingfeng.

Lei Xingfeng entered the continent, he had long been numb, these days, he has been running around in various new continents, sometimes seeing two or three new continents a day, the novelty has long been gone.

This is a rather desolate continent, there are some sparse plants, there are almost no large animals to be seen, the sky is light gray, Lei Xingfeng's eyes swallow silver rays, and then he saw a scene that is unforgettable in this life, and the entire continent is glowing with a faint light, which means that there are a large number of mines underground.

As for whether it was a natural energy crystal mine, Lei Xingfeng was not clear.

Xing Feng said: "We are digging in place, and there are all energy crystal mines here." ”

Lei Xingfeng said in his heart: "It's all natural crystal mines?"

Xing Feng released his true body, plunged his big hand into the ground, and lifted it hard, and the entire formation was lifted into a big pit, and after a few consecutive blows, the underground mine was exposed.

Lei Xingfeng looked at it blankly, and he wondered: "Well, although this mine is a natural crystal mine, it is ...... But the purity is too low......"

Xing Feng's two big hands were held from the ground, Lei Xingfeng estimated that he just held it with both hands, and at least seven or eight tons of ore were dug out, and then he saw Xing Feng's hands folded, a dazzling light flashed, and in a moment, a spherical crystal appeared.

The diameter of this spherical crystal is at least about one meter and a half, and a large crystal ball was instantly collected by Xing Feng into the wheel storage space.

Then Xing Feng plunged his hands into the ground again.

Lei Xingfeng was shocked and said, "How did you do this?"

Xing Feng was also surprised, and he said, "You don't know this purification method?"

Lei Xingfeng smiled bitterly: "I really don't know. ”

Xing Feng shook his head and said, "No wonder the crystals you use are so primitive, okay, I'll tell you how to do it." ”

In fact, this is just an application of energy, Xing Feng only explained it slightly, and Lei Xingfeng completely understood what was going on, the irregular spherical crystal was only a primary refining, and it had to be refined to get that kind of elongated energy crystal, a spherical crystal, which could be purified into about two to four long large crystals, and this kind of crystal was the energy used by high-level cultivators.

As long as he knows how to do it, he will not be lazy, he can dig ore in the underground mining area for a long time, and now with this efficient method, of course he will dig a lot.

The first crystal was formed, Lei Xingfeng was quite excited, although it was not as good as Xing Feng's refining, but he knew that as long as he dug a few more times, he would soon become proficient.

Lei Xingfeng's vision is different, so he can vaguely see the direction of the ore vein, there are also rich ores and poor ores here, but there are mines underground, the difference is that there are many ores in it.

So with the excavation, Lei Xingfeng naturally went towards the ore vein, rich ore and poor ore, the crystals refined are different, the crystal balls refined by rich ore, once it reaches the refining link, the same crystal ball, the refined crystal blocks obtained, there is a big gap in quantity.

For example, the crystal ball of rich ore may be purified and refined to produce four or five crystals, while the crystal ball of poor ore may only be purified into two, or even only one crystal.

Digging along the vein, Lei Xingfeng's harvest was much larger than Xing Feng's, and soon, he found a large ore vein, and immediately beckoned Xing Feng to say: "Senior, dig from here!"

Xing Feng came over, he lifted the ground, just tried it and understood that this was a very good vein, he was surprised: "How do you know?"

Lei Xingfeng said with a smile: "I just dug here, and I found a difference. ”

Xing Feng praised: "Okay! It's much easier now!" "Finding the veins of the rich ore can save a lot of time, and it can save a lot of rotation space, but with the same volume, you can get more refined crystals, and the efficiency can definitely be improved a lot.

After digging for more than ten days in a row, until the wheel storage space was full, Lei Xingfeng began to refine and purify, and Xing Feng was still digging, his wheel storage space was even larger than Lei Xingfeng, and it would take a lot of time to fill it.

It took more than ten days, Lei Xingfeng finally purified all the spherical crystals and obtained thousands of long crystals, he sighed in his heart, no wonder Xing Feng didn't care about the consumption of crystals, it turned out that he could get crystals like this.

Lei Xingfeng looked back, the ground was in a mess, a deep ravine was left behind him, thousands of meters long, seeing that Xing Feng was still digging, Lei Xingfeng knew that the opportunity was rare, and threw himself into the excavation work again.

A large number of refined and purified crystals were piled up in the wheel storage space, and Lei Xingfeng felt a little satisfied.

After digging this day, Lei Xingfeng and Xing Feng sat down to rest.

Lei Xingfeng said, "Do people come here often?"

Xing Feng said with a smile: "It is true that many people come, but there are not many people who can get out alive. ”

Lei Xingfeng asked while purifying, "Why?"

Xing Feng smiled a little evilly, and he said: "Because this is one of the lairs of the star beast, as long as it is discovered by the star beast, unless you have the strength to resist, you will die, hehe." ”

Lei Xingfeng was startled and said, "What? Star Beast Lair ......"

Xing Feng said: "Yes, the lair of the star beast, there are a large number of adult star beasts here, hehe, but the place we arrived at was carefully selected, and there are quite few star beasts in this area, if you really go to the lair of the star beast, the natural crystals there are the real best, but who dares to go? Even if I don't dare to go." ”

Lei Xingfeng said: "With the strength of your predecessors, don't you dare to go?"

Xing Feng said: "What are you going to do there, before you can mine, a large number of star beasts will gather, even if you can resist it...... What's the use of not mining? We're here to mine, not to fight the Star Beasts. ”

Lei Xingfeng said, "What if I meet a star beast here?"

Xing Feng didn't care and said: "Even if you encounter a star beast here, it won't be a group, a single star beast, do I need to be afraid?"

Lei Xingfeng is right to think about it, even if there are more natural crystals in the lair of the star beast, but if you can't get it, it's better not to go, although there are many poor mines here, but the interference is also small, you can dig slowly, accumulate slowly, it's better than fighting with the star beast, and you can't get the crystal mine, it's much stronger.

Xing Feng said with a smile: "When I first discovered this place, many people came to excavate, and not many of them were able to go back alive in the end, haha." ”

Lei Xingfeng heard this guy's gloating tone and said, "If there were no star beasts, this place would have been hollowed out a long time ago." ”

Xing Feng said: "People who are not particularly powerful dare not come in." ”

As he spoke, Lei Xingfeng saw a black shadow appear in the sky, and he stood up and said, "It seems to be a star beast." ”

Xing Feng looked up and said, "It's really a star beast, well, it's okay, a single star beast can't threaten us at all, if you come to provoke us, you must go all out to keep it, otherwise it will attract a group of star beasts." ”

Lei Xingfeng said: "I hope he didn't find us." ”

Xing Feng said: "The eyes of the star beast are amazing, it is estimated that it will see us before we see it, in fact, we can already go." ”

Lei Xingfeng hadn't tried to do it since this big promotion, and when he saw the star beast flying over, he felt a little eager to try it, and wanted to try his strength.

Xing Feng saw what Lei Xingfeng meant, and he smiled: "Want to fight with the star beast?"

Lei Xingfeng said: "Yes, I want to try, can I resist the attack of the star beast, with the predecessors, the danger will be much smaller." ”

Xing Feng smiled and said, "Go, go, I'll just look at it." "Actually, he is not optimistic about Lei Xingfeng, if Lei Xingfeng can be at a higher level, there will probably be no problem, it is still a bit mysterious, what kind of star beast has he seen, and the strength of the star beast is also high and low.

Sure enough, the star beast circled in a big circle, and finally flew towards Lei Xingfeng and Xing Feng.

Xing Feng said: "Haha, it's up to you, this should be an iron-boned star beast, a kind that is difficult to entangle, with rough skin and thick flesh, it is difficult to fight." ”

The Iron Bone Star Beast is a metallic star beast, and its characteristic is that it is difficult to fight without death, it is reinforced and iron-bone, and it is a good hand in hand-to-hand combat, and it is the most headache for cultivators to see, it can grind people to death.

When the Iron Bone Star Beast approached, Lei Xingfeng couldn't help but exclaim, "What a beautiful Golden Star Beast!"

Xing Feng said on the side: "Iron Bone Star Beast, also known as Golden Star Beast, hehe, beautiful is beautiful, but it is difficult to entangle. ”

Extremely beautiful streamlined body, flying in the air, like a golden dragon, although it is very different from a dragon, but it looks like it is indeed an extremely beautiful creature, it has a slender neck, a pair of triangular golden wings, a slender torso, and a long tail, red eyes, staring at Lei Xingfeng and Xing Feng, the threat is direct and dangerous.

Lei Xingfeng had a creepy feeling, this star beast gave him great pressure, he knew in his heart that if he didn't reveal his true body, he couldn't fight with the star beast, his sword mark was not strong enough, and after the thunder seal was completely updated, the sword seal was basically still the original refining, it was no longer suitable for use, the power was too weak, and fighting with the star beast was useless at all.

In an instant, Lei Xingfeng released his true body, a huge body, and immediately erected, a true body that was more than eighty meters high, which was even larger than the body of the Iron Bone Star Beast, this Iron Bone Star Beast, also fifty or sixty meters long, was a behemoth, if there was no real body, Lei Xingfeng was a small ant in front of it.
