Two huge two-headed monsters, similar to the prehistoric Tyrannosaurus rex on Earth, but now they have two heads. Dust × edge? Literature← and Learning ↙ Network

"Roar!"

The monster roared angrily, opened its huge mouth, and bit Luo Meng and the others.

Luo Meng held the sword in both hands, jumped twenty or thirty meters high, and slashed at the monster.

The murderous aura rose into the sky, and a cold light slashed towards the monster.

Yang Xiao originally thought that the monster would be killed by Luo Meng's sword, but who knows, a white light curtain suddenly flashed in front of the monster.

Buzz,

Luo Meng slashed his sword at the white light curtain, and the light curtain trembled violently, but it did not break.

The monster "snorted" at Luo Meng in mid-air, and spewed out a whirlwind, Luo Meng's body was like a fallen leaf in the autumn wind, fluttering in mid-air, flying to a place more than 100 meters behind him, barely doing a backflip, and falling to the ground.

At this moment, more than a dozen tower warriors and three black-cloaked men had already run forward and began to besiege the two monsters.

Du Tianxing hesitated, walked out of the elevator, took out his long sword, and prepared to rush over.

Yang Xiao grabbed Du Tianxing,

"What do you want to do?"

"I'll help you, such a good opportunity, show it, maybe there will be unexpected gains, even if it's in the back, let's go together, right?"

Du Tianxing wanted to be opportunistic and courteous.

"If you don't want to die, go up!"

Yang Xiao said lightly, staring at the battle scene with his eyes.

Du Tianxing was immediately stunned, looking at Yang Xiao, and then at the battle scene in the distance, not knowing whether to go or not?

Du Tianxing also had the same idea, Gu Beifeng,

Gu Beifeng and a few people were about to go down the mine, and when they saw the battle in the distance, they rushed up with five people with a shout.

Yang Xiao wanted to stop it too late,

Gu Beifeng and Yang Xiao were dozens of meters apart.

"Gu Beifeng, don't rush up, you are not opponents, retreat quickly!"

Yang Xiao shouted loudly.

Where is Gu Beifeng willing to listen, with a shout, his figure flashed, turned into a ten-meter-long Siberian tiger, rushed up, and slapped a palm at a monster in the air.

Rumble!

Gu Beifeng's huge tiger claws slapped on the white defensive light curtain of the giant beast, Gu Beifeng only felt a shock in his body, and he retreated directly backwards, spitting out a mouthful of blood.

Just the monster's anti-shock power made Gu Beifeng unable to bear it.

Gu Beifeng and the others dared to rush forward, not because they were confident in themselves, but because they saw more than a dozen iron tower warriors and 3 black-cloaked men resisting the monster in front.

With their knowledge of the Iron Tower Samurai, they know that their combat power is extraordinary, and it should not be a problem to deal with the two-headed monsters, so they rush up to make a show, take a good impression, and find some opportunities for change in their lives here.

The other four also used their soul skills, giant pythons, lizards, werewolves, and spiders, attacking the two monsters one after another.

More than a dozen tower warriors and three black-cloaked men also held their long swords and slashed at the monster.

The whole mine was suddenly murderous,

Yang Xiao was fifty or sixty meters away from the battle scene, and he still felt a palpitation.

The white light curtain in front of the two monsters trembled violently,

Under the combined attack of the tower warrior and the man in the black cloak, it was finally unbearable, and with a click, it shattered into pieces.

Gu Beifeng and the others were about to cheer, and suddenly felt bad,

The dozen or so tower warriors and black-cloaked men suddenly flashed all over their bodies, and each of them sacrificed a defensive light curtain in front of their bodies.

When Yang Xiao saw it, he yelled badly, pulled Chi Lin and Ma Jiu, who were standing at the mouth of the well, into the elevator, and pressed the button of the elevator at the same time, and the elevator immediately slid down into the mine.

Du Tianxing stood in front of the mine and saw that the two monsters each stimulated a ball of golden light at the moment when the defensive light curtain broke.

Rumble!

The golden light exploded in an instant, and the violent storm air flow exploded instantly, facing the direction of the Iron Tower Samurai and the others, and the purple sand and dust in the sky instantly swept and wrapped all the people within a hundred meters around now.

Du Tianxing felt a threat of death, and immediately turned around and jumped backwards into the mine.

At this time, the mine elevator has slipped about twenty meters,

Du Tianxing's body landed on the lift.

Yang Xiao and the others first heard a shocking bang outside, and then the earth vibrated and the elevator shook violently a few times.

Then, there was a fierce fighting and the roar of monsters outside.

The elevator had descended to about fifty meters, and a violent purple storm rushed down directly from the wellhead.

Zhao Ben looked at it and exclaimed:

"Ouch, it's miserable, what should I do?"

There is an acceleration button on the lift,

Yang Xiao pressed it all of a sudden, and shouted:

"Defensive Light Shield!"

Du Tianxing and the others immediately hummed, and provoked a defensive light shield on it.

And at this moment, the elevator is also accelerating downward.

Rumble!

There was a violent explosion, and Yang Xiao and the others felt the crater vibrate, and the rubble fell down like raindrops on it.

Fortunately, after a long distance of running, the storm was already at the end of the strong crossbow at this moment, and the elevator had fallen rapidly, and the light shield of Yang Xiao and the others withstood the gravel falling from above, and there was no major problem.

Bang,

When the elevator reached the bottom of the mine, Yang Xiao and the others immediately jumped out of the elevator and ran into the huge mine.

There was a clattering noise, a pile of rubble fell, and calm returned to the outside.

Yang Xiao and the others were hiding in the mine at the moment, frightened.

"There's no sound outside."

"Is the battle out there over?"

"Did the monster win, or did Luo Meng and the others win?"

"God knows."

"Would you like to go up and have a look?"

"Crazy, you're looking for death, in case the monster wins, aren't we going up now to die?"

"Then wait."

......

Taking advantage of the waiting time, everyone began to observe the situation inside the mine.

This mine has been dug and there is a tunnel five or six meters wide and three or four high, as for how long this tunnel is, it is not known for the time being.

There is a light-emitting device every ten meters inside the tunnel, which is supposed to be used for lighting, similar to the emergency lights on the earth.

The walls of the tunnel are all purple rocks,

The entire tunnel is covered in purple rock, but there is no crystal ore like that.

Some rocks are very light purple in color, some are very deep and opaque.

Yang Xiao picked up a purple rock, feeling very heavy, very dense, much heavier than the same iron block on the earth.

"What kind of stone is this, so heavy?"

Ma Jiu picked up a purple stone and said:

"It is very dense, more than twice that of tungsten metal on earth."

Yang Xiao was stunned,

"How do you know?"

"I majored in geology and mining at university."

Ma Jiu smirked.

Du Tianxing, who has a master's degree in biology, immediately asked:

"Brother Ma studied geology and minerals? So can you judge what these purple rocks are in front of us? ”

Ma Jiu smiled:

"I used to study the geological ores on the earth, and I don't understand the geology of this strange planet, but according to the judgment of common sense, this kind of purple rock must contain some special elements, and those purple transparent crystals are the natural crystals of this kind of mineral elements, do you know crystal?"

Yang Xiao and the others nodded.

Ma Jiu continued:

"This purple rock contains this mineral element, but it cannot be used directly, and the purity is not enough, or it cannot be refined, and those purple crystals are mineral crystals, which are very pure and can be used directly."

Yang Xiao was stunned,

"Luo Meng and the others seem to attach great importance to this purple crystal, you say, what is the purpose of these purple crystals?"
