The light in his hand flashed, and a slightly yellowed ancient book appeared in Lin Meng's hand. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Lin Meng opened the book in his hand, looked at it carefully, raised his head again, and compared it with the surrounding terrain from time to time, as if he was looking for some traces left by the mining of black underworld.

However, judging from Lin Meng's tightly furrowed brows, the progress was not smooth.

Half a day later, Lin Meng had already crossed the 'Black Rock' mountain range, more than a dozen peaks, but still found nothing.

At this moment, the look of hope on Lin Meng's face had long since disappeared, and was replaced by a gloomy color.

"Hey, this place...... It's very similar to the entrance to the 'Black Stygian Stone' vein recorded in this book!!"

Suddenly, Lin Meng's body moved, appeared on a mountain peak with a small slope, looked at the black rocks exposed around him, and his face moved.

"Earth, scan the surrounding terrain, and then compare it with the map in this book to narrow down the scope of the search!" Glancing around, Lin Meng immediately commanded in his mind.

"Didi, understood!!"

Moments later......

"Didi, the most likely place, in front of the main body, under the huge mountain rock ten meters away!"

The electronic sound of 'earth' in his head couldn't help but make Lin Meng's face happy.

As soon as his figure moved, Lin Meng appeared under the black mountain rock that 'Earth' said, and after looking at it for a moment, Lin Meng's face moved.

"Roar!"

The next moment, a violent roar sounded, and in front of Lin Meng, a huge black knight appeared, which was the flame warrior summoned by Lin Meng.

With a "boom", the fire flashed, and in the hand of the 'Flame Warrior', a huge flame long sword immediately appeared, and then with a wave of his arm, the long sword in the hand of the 'Flame Warrior' did not have the slightest hindrance, and all of it was submerged into the mountain rock in front of him.

The Flame Warrior' turned his arm slightly, and he saw a huge black mountain rock, which had been dug out of the ground by the Flame Warrior and thrown aside.

Under the urging of Lin Meng's spiritual power, the 'Flame Warrior' was like a tireless coolie, waving the flame sword in his hand and constantly slashing towards the mountain rock in front of him.

In a matter of moments, the tall figure of the Flame Warrior slowly sank beneath the ground until it was gone.

And in front of Lin Meng, on the slightly sloping hillside, a man-high cave was revealed.

Seeing this, Lin Meng followed behind the flame warrior and walked into the cave he had dug out with an expressionless face.

Under the black cloak, Lin Meng's eyes flashed with silver, and his black eyes turned into two moons again, and then he saw Lin Meng walking on the ground in the dark cave.

After walking for less than a moment, Lin Meng's brows were tightly furrowed.

At the speed at which the flame warriors were digging a hole, Lin Meng had already gone deep into this mountain, extremely deep, but he still hadn't seen it, the mine path left by the previous 'Black Stygian Stone', Lin Meng couldn't help but feel a little depressed, and wondered in his heart if he had found the wrong place, this was not the vein of the ancient 'Black Stygian Stone' at all.

After walking for a while, there was still nothing to find, Lin Meng made up his mind, as long as he had a few more moments, if he still found nothing, then he would turn around and go out and move towards the next target.

"Bang!"

At this moment, suddenly, a dull sound came, in the empty stone path, extremely abrupt.

Originally, when Lin Meng was already hesitating whether to exit this cave, he couldn't help but be overjoyed when he heard the sound, and his spirit was greatly lifted, and he hurriedly walked forward in three or two steps.

Lin Meng had clearly felt that there was a tiny air flow through the cave, although it was very inconspicuous, but how could he hide it from Lin Meng, who was a first-level wizard at this moment.

The further he walked, the more fresh air came in front of him, which made Lin Meng's spirits lift.

Lin Meng saw that on the mountain wall in front of the flame warrior, a gap a foot wide appeared, but it was slashed out by the long sword in the flame warrior's hand.

Seeing the crack, Lin Meng's face moved, and he saw that the flame warrior's arm suddenly moved, the fire rolled violently, and the long sword in his hand slashed at the crack on the mountain wall again, making a 'bang' sound.

"Bang bang bang" followed by a series of loud sounds.

After a few breaths, the crack was seen to be transformed into a huge stone cavern that could pass through an adult man, under the slash of the flame warrior.

Then, the flame warrior, with a flash of form, turned into a flash of fire, passed through the huge crack, and appeared in the passage inside.

The next moment, in the dark passage, the firelight flashed, and I saw that the dark passage inside was bright.

Lin Meng's eyes froze, and he took a clear view of the situation in the passage, the entire passage was high by one person, and there were traces of axes and chisels all around, which were obviously artificially opened up, it looked like it had been some years, the ground was not wet, and there was a hidden vent.

After a while, seeing that there was nothing wrong with the flame warrior in the passage, Lin Meng moved his body, walked in through the crack, and appeared beside the flame warrior.

Feeling it slightly, the direction of the air flow in the passage, Lin Meng's eyes flashed, and he took the flame warrior and walked towards the depths of the passage.

Because this passage was the mine that mined the 'Black Stygian Stone' back then, the ground was trimmed very flat, and Lin Meng walked in the middle of it, and the speed was very fast.

"Well, this ......"

After a long time, Lin Meng, who was suddenly moving quickly, was stunned, looking at the two black passages that appeared in front of him, he couldn't help frowning, and he didn't know which side to choose for a while.

After pondering for a moment, Lin Meng didn't have any clue, so he had to choose a left passage at random and walked down behind the flame warrior.

Two tall figures, one in front of the other, more than ten zhang apart, walking in the dark mine road, the sound of knocking footsteps, in the deep and narrow, in the passage, back and forth, can not help but be a little gloomy.

Half an hour later, I saw Lin Meng walking out of the previous mine passage with a gloomy face, and then walked towards the previous passage without stopping.

However, it was Lin Meng who found nothing in the previous mine, and all the 'Black Stygian Stones' in that mine were mined out without any left, which made Lin Meng's heart full of hope again, a little gloomy.

Half a day later, standing in the depths of the underground mine, Lin Meng frowned deeply.

In this half day, Lin Meng walked through almost all the underground passages, except for a few 'black dark stones' scattered on the ground of the passages, there was no gain.

And this is not only to prove that this mine once produced the 'Black Stygian Stone', Lin Meng did not find the wrong place accident, and it is of no use.

"It seems that the 'Black Stygian Stone' here has already been mined, so there is no need to waste any more time here, hurry to the next place!" Lin Meng said to himself.
