In the forest, Liu Lan couldn't help being startled after hearing Lu An's words, and asked, "What's the problem?"

Lu An glanced at Liu Lan and said, "Purple gold is rare, and purple gold ore is also very hard to find, so it is very valuable. However, most of the purple gold ore grows in very high and wide mountains, and it does not appear in the mountains, but in the mountains.

underground."

"Although the mine just now is not shallow, it develops towards the center of the mountain, with a slight increase in density, rather than developing underground. This alone is not in line with the rules of the Zijin Mine."

"Another point is the shape of the purple gold ore." Lu An said seriously, "The shape of the newly mined purple gold is very irregular, with different sizes and shapes, and there will never be obvious cuts. But just now

Every purple gold I see is almost the same, the size is definitely different, and the shape also has obvious facets, but it still does not conform to the ordinary purple gold mine style."

"So, I think this is not an ordinary purple gold mine. I'm afraid there is a hidden secret, and the hidden secret is in the core area." Lu An thought for a while and said, "It's just that we don't know whether it is good or bad yet. But

Just be careful."

After listening to Lu An's long words, Liu Lan's expression was obviously a little dazed. The two of them were still walking, Lu An was thoughtful, while Liu Lan kept looking at Lu An.

"How...how do you know this?" Liu Lan came to her senses and asked the question in her mind, "Have you seen the Zijin Mine?"

Lu An was startled when he heard this, then nodded slightly and said, "I've seen it elsewhere."

Lu An has indeed seen that when he was a slave, slaves were the absolute main force in all mining areas, because the mountain is very stable, and it is impossible for the Celestial Master to reinforce the mountain for safety, which will also cause trouble for mining. It does not matter whether the slaves die or not.

, Lu An and his parents both worked in the same Zijin Mine. It was precisely because he worked in the Zijin Mine for a long time that Lu An knew so many things.

"The people who were in the mine just now were all slaves, right?" Lu An looked at Liu Lan and asked softly.

"Ah, yes!" Liu Lan nodded quickly and said, "What's wrong?"

"Let the wood attribute Celestial Master support some pillars in the walls of the mine, and apply more protective measures to ensure the safety of the people inside." Lu An said, "Also, there must be Celestial Masters guarding outside the mining area at all times.

Well, if anything happens, let me know immediately, no matter when it is

.”

Liu Lan was stunned again when she heard this, and looked at Lu An in surprise, thinking that he had a fever and couldn't function properly, so she asked, "Why?"

"No reason, just do it." Lu An did not explain, just said calmly.

Liu Lan looked at Lu An and didn't understand at all, but since it was Lu An's order, she still nodded and said, "Okay, I'll find someone to take care of it when I get back."

"By the way, there is one more thing." Lu An thought for a moment and said, "Let all the slaves rest tonight and stop digging the mines. Wait until I give the order tomorrow morning before mining again."

"Why is this?" Liu Lan is completely confused about Lu An's decision. Isn't this just a waste of time?

Lu An stopped and looked at Liu Lan and said, "I can't tell you now. I'll wait until tomorrow morning."

"..."

At night, the mountains and forests are silent.

It was already dark, and the moon was hanging high above our heads. The trees in this mountain forest were very ordinary, and they were not densely packed. However, in the mountain forest, a black shadow passed quickly.

This black shadow was extremely fast. An ordinary person would not be able to see any shadow. At most, he would feel a gust of wind blowing by. The black shadow moved forward quickly and soon reached the edge of the core area of ​​the Zijin Mine.

This person is none other than Lu An.

The reason why he asked the mining workers to rest tonight was because he wanted to come to the core area to find out in person. He was afraid that if he entered the mountain, it would cause vibrations or collapse, which would harm the workers.

The scorching sun was shining brightly, and Lu An felt that there were many enemy heavenly masters guarding the edge of the core area. However, the strength of these heavenly masters was not high, and they were only level three heavenly masters at most. Lu An did not need to enter the Demon God's Palace.

environment, you can perfectly avoid everyone and enter the core area.

Bypassing everyone's sight, Lu An quickly arrived at the core area. As expected, there was no trace of any development or any trace of investigation in the core area.

Obviously no one in Quang Ngai City suspected that there was something fishy here, and he was the first one.

Lu An stood in the center of the mountain and looked around at the surrounding environment. Along the way here, he found that the trees in the mountain forest were getting rarer and rarer, and they were not as tall as those on the outside. He saw these things and did not ignore them.

.Even the soil under your feet is very soft, with almost no stones.

Lu An felt even more strange, and he came here late at night just to find out what happened, so he no longer hesitated and rushed directly into the land at his feet.

Although Lu An is not an earth-type heavenly master, and his ability to escape from the earth is not fast, the ground is not hard. He walked a full two feet before encountering a rock. What's more, what worries Lu An is that the rock is also brittle.

It was so strong that it almost broke apart at the first touch. Lu An's forward speed was not affected at all, and he quickly moved towards the inside of the mountain.

Along the way, there was nothing weird except for the fragility of the rocks. The only thing that concerned Lu An was that the closer you got to the bottom, the more purple gold ore there was around, and the size was getting bigger and bigger.

Lu An knew that with his own speed, he had never reached the underground and was still in the mountain. But so far, the amount of purple gold in the surrounding area was outrageous. The number of these purple gold mines was more than Lu An had ever seen before.

Several times, which is completely different from what ordinary purple gold ore should have.

It seemed that his guess was correct. Lu An became more and more convinced of his idea, so he headed downwards faster.

The mountain was only a hundred feet high, so Lu An left a channel as high as a hundred feet from top to bottom. As he moved forward, he froze the place he walked with ice, forming an ice channel so that his

It will be more convenient to come next time.

After Lu An's hard work for a full two-quarters of an hour, he finally reached the bottom of the core of the mountain. Further down is the underground, not the mountain. However, even if Lu An is in the mountain, he has no idea about the distance.

If you are sensitive, you will not know that you have just reached the horizon.

However, he stopped just at the horizon because he suddenly felt that he encountered huge resistance on his way forward.

hard.

Truly as hard as iron.

Lu An stood on the ground, leaned over and touched the surface with his hands. He found that the surface was very flat, and even after sweeping away the soil, it was smooth, just like a huge iron plate. Lu An's eyes were slightly focused, and a picture appeared in his hand.

The ice dagger split the rocks under my feet.

Even if it is real iron, with Lu An's current strength and the power of Xuan Shen Ice, it will be as sharp as mud, not to mention these are still rocks. However, this did waste a lot of Lu An's strength, and his forward speed was also greatly slowed down.

The further they advanced, the harder the rocks became. After passing twenty feet, Lu An even had to expend great effort to break away the rocks before he could move forward slowly.

Finally, Lu An stopped when he was about thirty feet underground. He was out of breath after walking on the mountain and underground for a long time. There was very little air in the land, and he also felt dizzy. Of course he stopped.

It's not because of this, but because there is no longer rock under his feet.

But ------- a large piece of real purple and gold wall.

That's right, it's a purple gold wall, a real purple gold wall. Although the appearance of this purple gold wall has been obviously damaged, with a lot missing, Lu An followed the purple gold wall under his feet and found that it was definitely a huge purple gold wall. I'm afraid those spreading

The purple gold that has gone out has also fallen off from the purple gold wall and spread out over the years.

There are so many purple gold mines outside, it is enough to imagine how huge this purple gold wall is.

However, Lu An was no longer interested in money, so he was not too happy. Instead, he was more concerned about why there was such a big purple and gold wall here. Is it just this purple gold wall, or is there something else hidden under this wall?

After Lu An thought calmly for a moment, he froze the surrounding walls again, but did not freeze the purple-gold wall under his feet. Then, he quickly returned upwards, all the way to the surface of the mountain.

Under the moonlight, there was not even a ghost in the entire forest. Lu An was the only one standing at the entrance of the cave. After he used the scorching sun to confirm that there was no one within a mile, he pointed his palms at the bottomless cave entrance in front of him.

Take a deep breath.

In an instant, two huge and majestic flames surged out from his hands and went straight into the deep cave!
Chapter completed!
