The second mine site is in better condition. There is a small black crystal mineral vein. Although there are traces of being mined, some are still left. The vein is something similar to a metal ore, and most of it is impurities, black crystal.

It's just hidden in it. How many mysterious crystals you can find depends on your luck after mining.

"This should be the Xuanjing vein... Hey, what are you doing?" Lin Feng didn't even finish his words when he was made to laugh or cry by the actions of Chen Yuan and Qian Qian.

The two men had already rushed to the mineral veins like hungry tigers, holding flying swords and trying to dig out the minerals. They could only hear the "ding-ding-ding-ding" sound, and the sound was very clear, but after cutting with the flying swords for a long time, they could not cut off a piece of ore.

.

"Mining, hurry up, hurry up, you all come here. When others come, they will grab it." Chen Yuan kept urging others.

Lin Feng was stunned, and then he struggled to hold back a sentence: "You use flying swords... to mine?"

You must know that Xuanjing itself is a spiritual weapon-level material, and the hardness of Xuanjing veins is between treasures and spiritual weapons. Although their flying swords are slightly harder than Xuanjing veins, they are still not enough for mining.

look.

"Of course." Chen Yuan replied.

Lin Feng said helplessly: "If you dig like this for a few years, I don't know if you can dig out enough Xuan Jing."

"What should we do?"

"Stupid!" Bai Ling said from the side, "Of course you use hoes, shovels, etc. to dig, there is no use of swords."

"Hoes, shovels?" Qian Qian said, "Those are only used by servants, how could I have them?"

Chen Yuan quickly echoed: "No matter what, I won't bring such a thing."

"It's just your size!" Lin Feng scolded with a smile, "Do you think ordinary hoes and shovels can dig out black crystal mines? Then at least you need a hoe with a spiritual weapon level! Otherwise, if you go down with the hoe, the mine will be mined.

If you don't dig it, the hoe must be useless."

The two of them were a little dumbfounded, Qian Qian said: "A hoe at the level of a spiritual weapon...who can forge these things?"

"That's right, who would be so stupid?" Chen Yuan agreed.

They stopped what they were doing, looked at the black crystal veins in front of them, and scratched their heads, but they couldn't think of any good solutions.

"You really can't do it without me." Lin Feng waved his hand, "You all stay away from me, stay away from me."

Chen Yuan was the most obedient. He was the first one to retreat far away without asking why. Then Qian Qian and Bai Ling also retreated away. Only Xia Yuxin asked strangely: "What do you want to do? Do you want to do something?"

Is there a hoe at the level of a spiritual weapon?"

"If you don't want to become Qin Hei, just stay away." Lin Feng took out a few bursting charms.

"Qin Hei... don't mess around!" Xia Yuxin reacted and ran away quickly.

Lin Feng carefully observed the Xuanjing mineral vein for a while. This thing was really unusual in appearance. It was a big mass, and it was difficult to find even a gap. If there were no gaps, the explosion spell would only explode outside.

The effect won't be very good.

"Boss, do you plan to use a spell?" Seeing Lin Feng's actions, Chen Yuan also reacted, "But this vein is bare and there is no place to put it in."

"You're not stupid." Lin Feng gave Chen Yuan a rare compliment, "However, you only know one, but not the other. You have to keep an eye on it."

Lin Feng placed an explosion spell on the Xuanjing mineral vein, but did not activate it. After everyone retreated, Lin Feng activated the explosion spell. There was a loud noise accompanied by a huge fire, and it exploded.

opened.

The raging fire burned on the black crystal veins. No fuel was needed. This was the effect of the explosion spell itself, and it would not last too long.

Just before the flames disappeared, Lin Feng suddenly hit two ice spells on the mineral vein. When the first ice spell took effect, the remaining flames of the explosion spell were quickly extinguished. The second ice spell caused the temperature to drop sharply.

The surface of the vein is even covered with a thin layer of ice.

"What is this for?" Everyone looked at it stupidly.

Not only Chen Yuan couldn't figure it out, but others couldn't figure it out either. Didn't he want to use the explosion spell to mine? Why did he use the ice spell to extinguish those flames?

"Click, click..."

Only a slight sound was heard, and the ice blocks outside the mineral veins gradually shattered. As these ice blocks fragmented, the mineral veins that were originally extremely strong and became a mass, actually had slight cracks!

This crack is so obvious that it is very deep at first glance, even going deep into the veins. You know, Chen Yuan and Qian Qian used their flying swords to cut for a long time, and they could only cut out a few not too deep cracks.

Scratches. And now, Lin Feng just used a few charms to scratch them on the outside. Can it have such a strange effect?

Dumbfounded, Qian Qian asked: "How is this done?"

Lin Feng said casually: "Heat expands and contracts with cold."

It's a pity that middle school students just don't understand things that all middle school students know, and all of them look puzzled.

Bai Ling asked: "What's swelling and what's shrinking?"

"Oh! I understand!" Chen Yuan suddenly shouted.

"Why, you still know about thermal expansion and contraction?" Lin Feng felt that he really needed to look at Chen Yuan with new eyes, because he couldn't tell that this guy was quite knowledgeable.

"Of course. When it gets hot, it will grow bigger. When it gets cold, it will shrink. All men know that. Hehehehe..." Chen Yuan laughed obscenely.

Qian Qian, who was next to him, also looked like he suddenly realized what he was talking about. He nodded and said, "So this is what Brother Lin was talking about."

"Damn!" Lin Feng almost vomited blood when he saw the lustful looks of the two of them. It turned out that what they were talking about was expansion with heat and contraction with cold. Their nature is hard to change.

"But what does thermal expansion and contraction have to do with cracks?" Qian Qian was still a little confused. "Although it can also be used to open cracks, they are already existing cracks and are used to insert them...Brother Lin, what are you doing?

How was it done?"

Bai Ling, who was next to him, turned red when he heard this, and said angrily: "What a pervert!"

"What are you talking about?" Xia Yuxin still didn't understand and became even more confused.

Wow, can't you tell that a little girl who can look so seductive can be so pure? Lin Feng was really surprised that she hadn't reacted yet. Thinking about it, she hadn't been with her mother since she was a child, so it was considered...

In a single-parent family, there is only the father, so he may not have the opportunity to learn these things, and her two little girls may not dare to say such things.

It seems that I should be responsible for the enlightenment education in the future... Hehehehe, Lin Feng started to think wildly.

"What are you talking about?" Xia Yuxin asked strangely, "What about thermal expansion and contraction, and what about insertion into cracks?"

"Uh." Qian Qian was a little embarrassed and said quickly, "Sister-in-law, you have to ask Brother Lin about this, we don't dare to talk nonsense."

"Go away!" Lin Feng scolded, "You are just thinking nonsense. Thermal expansion and cold contraction means that when something is hot, it will expand, and when it is cold, it will shrink, and then... Hey, don't look like that.

Is that okay? What I’m talking about is serious! Everything will expand with heat and shrink with cold. Sudden changes in temperature will lead to rapid changes in volume, which may lead to rupture. Forget it, I tell you, you don’t understand! Anyway, I know.

That’s all it is!”

The effect of thermal expansion and contraction is very strong. Even high-hardness alloys will crack and break when the temperature suddenly changes. Although the Xuanjing vein is as hard as alloys, it is not tough, that is,

It was very brittle. Under the sudden alternation between the explosion spell and the ice spell, a large number of cracks immediately appeared.

Now that there were so many cracks, it was easier to deal with. Lin Feng took out the Exploding Talisman again, and this time, he stuffed the Exploding Talisman into the cracks.

"boom!"

With the arrival of the second loud noise, a large area of ​​Xuanjing ore vein was blown to pieces, and small pieces of ore were scattered on the ground.

This is the "blasting method" in mining. Lin Feng is now using the blasting method to collect these hard black crystal minerals.

"It's amazing..." Several people looked at the black crystal mines scattered all over the ground and couldn't believe it.

After reacting, they rushed forward and picked up the broken ores. On the broken fractures of the Xuanjing ore, several pure black, shiny things could be found. These were Xuanjing.

They collected some of these broken minerals and put them into storage bags. Those mysterious crystals were all born in the mines and could not be taken out at once. They would have to wait until they had time to do it slowly.

The part of this black crystal vein that is easier to mine exposed on the surface has been mostly mined. The remaining residual veins are buried deeper, and even with the explosive spell, mining is quite inconvenient.

After taking a look at it, Lin Feng decided to give up here, so he called the other people to leave and went to the next possible mining site.

Not long after they left, Xuan Ye and the other three also arrived here.

They looked around and saw that the ground was in a mess, with obvious signs of an explosion, and there was a huge hole in the ground.

Xuan Ye frowned and said, "There seemed to be a strong explosion in this place just now. What's going on?"

"Young Master, look." Junior Brother Pang pointed to the pothole, "This vein seems to have been mined a lot. I guess it was done by them just now, right?"

Xuan Ye looked at the remaining mineral veins and frowned even more: "They actually used explosive methods to mine? This method is quite interesting. Even I didn't expect it... I really underestimated them."

Junior Brother Hou asked: "Young Master, there are still some remnants of this mine, do we want to dig some?"

"What the hell! Let's go to the next location, hurry up, don't get robbed again!" Xuan Ye said a word and took off first.

Xuan Ye is usually very calm, but now he can't hold his breath. He originally thought that the strength of his three-person team could completely overwhelm any other team, but now this confidence has been shaken. Xuan Ye doesn't care about a few Xuan Ye.

Jing, but he doesn't allow anyone to perform better than him.

Now, in his desperation, he actually used flying, even if he consumed more real energy, he couldn't care less.
