Huge mines.

Wind and fire, black crystal ore is piled up, and greenhouses are built around it, and the Dark Demon Clan powerhouse can be clearly seen outside the mine. With a majestic body and muscles shattering like a mountain, the Dark Demon Clan powerhouse led by him was dressed in black armor and was more than three meters tall.

Demon Venerable Level!

Lin Feng can tell now, although it may not be accurate, but the body of the Dark Demon Clan's powerhouses will strengthen as their strength increases, and they are generally higher than two meters tall, but the Dark Demon Powerhouses of the Demon Venerable level are often more than three meters tall, and their bodies are stronger.

Of course, it's the Dark Demon Man.

"It's so heavily guarded."

"In this mine, there should be ore crystals that are useful to all the powerhouses of the Dark Demon Clan."

Lin Feng said secretly.

I don't know what it is for, but it's obviously a good thing.

Just like the dragon pearl obtained in the Wannsee World, he also didn't know because he didn't have enough experience.

"The miners in the mine, ten out of ten are humans." Lin Feng sighed lightly in his heart.

Here, I can hear the angry rebuke and whipping of the dark demon powerhouse, and at this time I finally understand what is the use of the dark demon powerhouse enslaving human beings - work. Just as humans once enslaved all kinds of beasts, animals, dogs, cows, horses, etc.

"I really can't find a human hideout."

"But, they know."

Lin Feng's eyes shone brightly.

Sometimes, the problem doesn't have to be that complicated.

Sou!

Lin Feng left.

…

Breaking into a mine to save people?

Lin Feng is not so stupid, he can save people, but he can't save himself.

At the moment, he has two options -

First, infiltrate the mine and become a miner.

But it's too hard to achieve, and every enslaved human I saw last time has a mark planted in their souls.

Second, wait for your chance.

"There used to be a lot of similar mines on Earth." Lin Feng quietly galloped outside the mine, searching everywhere, "Miners, live a miserable life. Eating the worst meals, not having the last meal, not being able to hand over enough ore, not only can you not eat, but you will also be abused. ”

"Miners die every day. Thrown into a mass grave to feed wild dogs. ”

Lin Feng probed carefully.

Outside the mine, the danger is not so high, but the search after round does not contain any similar 'mass graves'.

"Is that wrong?" Lin Feng frowned slightly.

Suddenly, his fists tightened. Qingjin exposed: "I forgot, they... It's a demon. ”

"A demon who eats people and doesn't spit out bones."

Lin Feng's eyes were dark.

…

Outside the mine.

Lin Feng was like a patient hunter, waiting for his prey to come to the door.

Every day, miners die, and naturally, new miners come in. Lin Feng was gambling, gambling on time, gambling on sending miners, not a Demon Venerable-level powerhouse. But he didn't put his eggs in the same basket and was always looking for other opportunities to complete the task.

Outside the mine. Lin Feng has already figured out the entire environment.

It was a nearly closed canyon with only one access and entrance, but there was a long river behind the mine, and in fact he came through the river, but he didn't expect it to be a mine on this side of the river.

Lin Feng explored the rear of the mine, uninhabited.

After waiting for two days, it would be a lie to say that there is no hurry, after all, time is really limited. If there is no shortage of manpower in the mine, or if the miners are replenished only once every two or three months, he is waiting for nothing. I was light-hearted. Lin Feng stepped on the deep mud and stone ground and smiled.

"It is said that there are often miners digging tunnels in the mines."

"Why can't I touch it?"

Lin Feng actually understood.

Miners are so strict in their surveillance, especially when they dig ore veins that even the Dark Demon powerhouses value, and they want to really dig a tunnel. It's not just a difficult word.

Wait a minute!

Lin Feng was stunned, and his eyes lit up.

"Digging tunnels, from the inside out, is really difficult."

"But from the outside in......"

But it's different!

"And I can dig a few more forks in the road, even if it is discovered, even if it is pursued by the strong of the Demon Venerable. It can also delay time and escape from the tunnel into the river at the first time. Lin Feng thought about it and carefully analyzed the possibilities, although it was not foolproof, but the probability was very high.

"Instead of putting your hopes on luck, it's better to-"

"Fight!"

…

If you don't enter the tiger's den, you can get the tiger.

The entrance of the tunnel is set on the shallow bank, one does not need to be covered, and the other is easy and convenient to escape and go straight into the river. The excavation of the tunnel was easy at first, but the further down the stone became, the harder it became, until it reached the middle of the tunnel.

"Whew!" Lin Feng's dark holy aura sank into the sea like a stone.

There is no half of the strength left, it is like a punch on cotton, and once again exerts the dark holy energy, but it still does not make half a wave. Lin Feng put his hand on the black stone in front of him, and his eyes burned in an instant: "Drink!" ”

The Red Fire Holy Qi burst out instantly.

Smack! The black stone shattered with a sound, revealing a black and translucent crystal.

"Holy Crystal!?" Lin Feng micro-sign.

The black crystal in front of him was similar to the holy crystal that trapped Xiang Yu's predecessors, but the energy contained in it was very different.

"I see." Feeling the rich dark holy qi stored in the black crystal, Lin Feng suddenly understood. Nine out of ten of the Dark Sacred Qi was absorbed by this Dark Saint Crystal, and the energy contained in the Sacred Crystal was quite huge, like a bottomless abyss.

"If I'm not mistaken......"

"There should be a lot of such dark saint crystals in this mine."

Lin Feng remembered the Demon Venerable powerhouse he had seen.

Almost every one of them wears a black armor made of this resembling a dark crystal. All things in heaven and earth have their own aura, and the earth has various elemental crystals, and in the dark demon world, it will naturally condense into various dark holy crystals.

"Actually, for me, the Dark World... It is a rare cultivation treasure land. Lin Feng said in his heart.

"If you don't have a mission."

…

Keep digging.

For a strong person who cultivates the Dark Demon Holy Qi alone, it is difficult to dig the ore here, but for Lin Feng, in addition to the Dark Holy Qi, he also has a variety of means, even if the strength of these ordinary stones exceeds the S-level defense of the earth, but for him now... Insignificant.

"I picked up twenty-three dark crystals." Lin Feng was very satisfied.

This is much more than the dark energy stored by plants, and if calculated in terms of energy alone, each of these dozens of dark crystals can be counted as a holy treasure.

The excavation of the tunnel was very careful, Lin Feng did not make any noise, and only relied on the holy qi to open the way.

Still, a day's digging was enough to get him into the mining area.

"Ding!" "Phew!" "Dingding!" …… Below, Lin Feng could clearly hear the sound of mining, the tired panting of human miners, **, and the angry voice of the Dark Demon Clan's powerhouse, which was enough to imagine everything in the mine, and how desolate the human race was.

As for the exit of the channel......

It's easy.

"There are some dark Saint Crystals there, but there is no mining sound, and there is none... The breath of the Dark Demon Clan's powerhouse. Lin Feng knew very well that there were generally two possibilities for such a place, one was an unexcavated vein, and the other was an unexcavated vein.

It's safer than anywhere else.

"Peng!" Lin Feng's dark holy qi condensed, and the top broke open in an instant.

Lin Feng jumped out, he had already sensed his surroundings, and he didn't have any life breath, including humans, including the Dark Demon Clan, but ......

The moment he came out, he was still taken aback. (To be continued.) )
