Lei Xingfeng couldn't figure out why Xing Feng was like this, but this was good news for him, not a bad thing. Even though Xing Feng was unconscious this time, he taught him a lot of useful cultivation knowledge, and Lei Xingfeng was still grateful for this.

Xing Feng opened his secret door and led Lei Xingfeng into a new continent.

Lei Xingfeng has long been numb when he entered the continent. He has been traveling around in various new continents these days. Sometimes he sees two to three new continents a day, and the freshness is gone.

This is a very desolate continent with some sparse plants and almost no large animals are seen. The sky is light gray, and silver light is spitting out from Lei Xingfeng's eyes, and then he sees a scene that will never be forgotten in his life. The entire continent emits a faint light, which means there are a large number of mines underground.

As for whether it is a natural energy crystal ore, Lei Xingfeng is not clear.

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

Lei Xingfeng thought to himself: "It's all natural crystal ore?"

Xing Feng released his true body, and his big hand suddenly penetrated into the ground. With a force, a large pit was lifted up in the entire strata. After several consecutive strokes, the underground mine was exposed.

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

Xing Feng held up his two big hands from the ground. Lei Xingfeng probably just held it with both hands, and at least seven or eight tons of mine was dug out. Then he saw Xing Feng's hands folded together, and a dazzling light flashed. After a moment, a spherical crystal appeared.

The diameter of this spherical crystal is at least about 1.5 meters. A large crystal ball is instantly stored by Xing Feng.

Then Xing Feng inserted his hands into the ground again.

Lei Xingfeng said in shock: "How did this be done?"

Xing Feng was also surprised and said, "Don't you know this way of purification?"

Lei Xingfeng smiled bitterly and said, "I really don't know."

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

In fact, this is just an application of energy. Xing Feng just explained it a little, and Lei Xingfeng fully understood what was going on. Irregular spherical crystals are just primary refining objects. They have to be refined before they can obtain the long energy crystal. A spherical crystal can roughly purify two to four long large crystals. This crystal is the energy used by advanced practitioners.

After following the example, Lei Xingfeng also released his true body and began to dig wildly. As long as he knew what to do, he would not be lazy. He could dig ore in underground mining areas for a long time, but now with such an efficient method, he would of course dig out very hard.

Lei Xingfeng was quite excited when the first crystal was formed. Although he was not as good as Xing Feng's refining, he knew that as long as he digs a few more times, he would soon become proficient.

Lei Xingfeng has different visions, so he can vaguely see the direction of the ore veins. There are also rich and poor mines here, but there are mines underground. The difference is how many ores are contained.

Therefore, as the excavation was achieved, Lei Xingfeng naturally went towards the ore veins. The crystals extracted from rich and poor ore are different. Once the crystal balls refined by rich ore are reached in the refining stage, the number of refined crystal blocks obtained by the same crystal balls is very different.

For example, crystal spheres of rich ore may be able to purify and refine four or five crystals, while crystal spheres of poor ore may only purify two, or even only one crystal. The efficiency of mining rich ore and mining poor ore is at least more than twice as good as that of mining.

Digging along the ore veins, Lei Xingfeng's harvest was much greater than Xing Feng's. Soon, he discovered a large ore vein and immediately called Xing Feng: "Senior, dig from here!"

Xing Feng came over, he lifted the ground, and just tried it and realized that it was a very good vein. He said in surprise: "How did you know?"

Lei Xingfeng smiled and said, "I just dug it here and found the difference."

Xing Feng praised: "Okay! It's much easier now!" Finding mineral veins that are rich can save a lot of time, and it can also save a lot of storing space. 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, until the space of Luzang was filled, Lei Xingfeng began to refine and purify it. Xing Feng was still digging. His Luzang space was larger than Lei Xingfeng. It took a lot of time to fill it up.

After spending more than ten days, Lei Xingfeng finally purified all the spherical crystals and obtained thousands of long strip crystals. He sighed in his heart, no wonder Xing Feng didn't care about the consumption of the crystals at all. It turned out that the crystals could be obtained in this way.

Lei Xingfeng looked back and saw that the ground was in a mess, with a very deep gully left behind, several thousand meters long. Seeing Xing Feng still digging, Lei Xingfeng knew that the opportunity was rare and devoted himself to the excavation work again.

A large amount of refined and purified crystals are piled up in the Lunzang space, and Lei Xingfeng feels quite satisfied.

After the excavation that day, Lei Xingfeng and Xing Feng sat down to rest.

Lei Xingfeng said: "Does anyone often come here?"

Xing Feng smiled and said, "There are indeed many people coming, but not many people 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 star beast's nests, 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's Lair..."

Xing Feng said: "Yes, the star beast's nest, there are a large number of adult star beasts here. Hehe, but the places we arrived at were carefully selected, and there are quite a few star beasts in this area. If we really arrive at the star beast's nest, the natural crystals there are the real best, but who dares to go? Even if I don't dare to go."

Lei Xingfeng said: "Don't you dare to go with the strength of your predecessors?"

Xing Feng said: "What are you doing there? Before you can mining, a large number of star beasts gathered together. Even if you can resist... what's the use of not being able to dig a mine? We are here to mine, not to fight the star beasts."

Lei Xingfeng said: "What if you encounter a star beast here?"

Xing Feng said without any attention: "Even if you encounter star beasts here, they will not be in groups. Do I need to be afraid of a single star beast?"

Lei Xingfeng is right to think about it. Even if there are many natural crystals in the star beast's nest, it is better not to go. Although there are many poor ore here, the interference is small. You can dig slowly and accumulate slowly. It is much better than fighting with star beasts and not getting crystal ore.

Xing Feng smiled and said, "I found out that there were many people coming to dig here, but not many people were able to go back alive in the end, haha."

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

Xing Feng said: "If you are not a particularly powerful person, you won't dare to come in."

While talking, Lei Xingfeng saw a black shadow appearing in the sky. 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 cannot threaten us at all. If you come to provoke us, you must do your best 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 star beast's eyes are so powerful. I guess it saw us before we saw it. In fact, we can leave."

Since Lei Xingfeng advanced this time, he has not tried it yet. When he saw the star beast flying over, he felt a little eager to try it out and wanted to try his strength.

Xing Feng saw what Lei Xingfeng meant, and he smiled and said, "Do you want to fight with Xingbeast?"

Lei Xingfeng said: "Yes, I want to try it. Can I resist the attack of the star beast? If you have seniors here, the danger will be much smaller."

Xing Feng smiled and said, "Go, go, I'll just look at it." In fact, he was not optimistic about Lei Xingfeng. If Lei Xingfeng could be higher than the next level, there would probably be no problem. It's still a bit mysterious now, so I can see what star beast it is. The strength of the star beast is also high and low.

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

Xing Feng said: "Haha, it depends on you. This should be an iron bone star beast, a very difficult type, with thick skin and thick flesh, and it is difficult to beat."

Iron bone star beast is a metal star beast, and its characteristic is that it is difficult to be beaten to death. Steel and iron bones are good at fighting. It is the most troublesome thing for practitioners to see, and it can kill people.

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 the Golden Star Beast, hehe, beautiful is beautiful, but it is difficult to deal with."

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

Lei Xingfeng felt a creepy feeling. This star beast put great pressure on him. He knew in his heart that if he did not reveal his true body, he would not be able to fight the star beast. His sword seal was not strong enough. Unlike the thunder seal after it was completely updated, the sword seal was basically refined and was no longer suitable for use. Its power was too weak, and fighting with the star beast was of no use at all.

In an instant, Lei Xingfeng released his true body, and his huge body immediately stood up. The true body, which was more than 80 meters high, was even larger than the body of the Iron Bone Star Beast. This Iron Bone Star Beast is also fifty or sixty meters long and is a giant. If there is no real body, Lei Xingfeng would be a little ant in front of it.
