This cave was also a mining place when it was not on Earth, and alien creatures would also mine here, and these oil lamps were left behind.

It's just that after this area came to the earth, both the people who mined in this mine and the previous creatures in the mine have mutated and become monsters. These oil lamps have become ownerless, and the first people to discover this mine can take them and use them.

Carrying the oil lamp, he continued to walk towards the mine, the ore at the entrance of the cave had been almost mined, and the only way to get high-quality ore was to go deep into the mine.

Continuing to walk forward, he heard a "whoosh", a fist-sized stone, smashed towards Xu Feng, extremely fast, like a cannonball, sounding extremely powerful.

Xu Feng turned to the side slightly, and the stone flickered from his side, hitting a rock behind Xu Feng, and with a bang, the hard rock wall actually smashed out a bowl-shaped hole with a diameter of half a meter, and the gravel fell down.

Looking ahead, a human-like monster with two thick arms on the upper body and four spider-like legs on the lower body was staring at Xu Feng not far away.

"Intruder, invasion...... Death, all death......"

A strange word sounded in Xu Feng's heart, and the monster on the opposite side also used a method similar to telepathy to roar at Xu Feng.

It's just that the monster on the other side doesn't seem to have any senses, only a few simple words, and in addition, it will attack any creature that enters the mine.

"Roar~" The monitor lizard beast kept jumping and roaring at Xu Feng's feet, but with its "petite" size, it had no deterrent effect at all.

"Rock Eater?" Xu Feng was slightly stunned, he had seen this monster before, he liked to devour all kinds of ores, high-quality ores, and let them evolve.

Xu Feng drew his crossbow and shot towards the monster.

Whoosh~

The short arrow hit the Rock Swallowing Beast, and several blood flowers appeared, the Rock Swallowing Beast didn't seem to feel pain, didn't have the slightest look of pain, grabbed a piece of gravel on the ground, and continued to smash towards Xu Feng.

"It's just a monster with one-star strength." Xu Feng's heart was slightly relieved, the Rock Swallowing Beast could rely on devouring ore to improve its strength, the higher the strength of the Rock Swallowing Beast, the higher the defense, and finally it could even be invulnerable and immune to all physical damage.

But the one in front of him obviously did not reach such a high level, Xu Feng took a sword flower and swung his sword towards the Rock Devouring Beast.

The long-range attack ability of the Rock Swallowing Beast can even be comparable to that of a two-star monster, but the hand-to-hand combat is very poor, once it is close, it has no time to grab rocks and throw, it can only use its bare hands, and its own defense is very poor, it is inferior to the Worm Man, at least the Worm Man still has a hard Worm Armor, and the One-Star Rock Swallowing Beast only has a layer of gray skin, although it is also very tough, but it can't resist Xu Feng's long sword.

Before a set of drizzling sword techniques was finished, the rock swallowing beast was already covered in scaly wounds, and its blood was empty.

Click~

The corpse of the dead Rock Eater quickly turned into a rock, then made a cracking sound from the inside of its body, and finally, split into several rocks.

A white crystal, half-exposed in a rock, sparkling.

This is a beast crystal similar to the insect crystal, Xu Feng took it out and put it in the storage ring, now this one-star beast crystal has no help for him to improve his level, but it also has some value, which can be sold to obtain fate points.

Then, Xu Feng threw a collection spell at the corpse of the Rock Swallowing Beast, and several pieces of ore with a glittering black luster emerged from the corpse of the Rock Swallowing Beast.

"13 quality black iron ore, 19 quality copper ore, quality 6 silver ore ......"

Xu Feng distinguished them one by one and shook his head, they were just some low-grade ores, which were of little use, but they could also be used as task items to complete the collection tasks issued by the will of the earth.

Continuing to walk towards the depths of the mine, he encountered several more Rock Devouring Beasts along the way, none of which exceeded two stars, and were easily sent away by Xu Feng, and also obtained some low-level ores.

In the depths of the mine, pieces of fist-sized ore gradually emerged on the rock wall, exuding a faint light, the more you go inside, the stronger the light, at this time the oil lamp is useless, Xu Feng extinguished the oil lamp, and hung it on the hook of a rock wall.

Ding, ding, ding~

Suddenly there was a sound of mining in the distance, and there was a deep silence in the mine, and a little movement could be transmitted far away.

"Someone arrived before me and started collecting ore." Xu Feng thought in his heart.

In his previous life, in order to survive, Xu Feng worked as a miner for a long time, mining in the mine.

Although most of the excavated ore is handed over to the union that guards the mine, it is possible to have some left, and sometimes, when you dig up high-quality ore, you can make a small fortune.

If you meet other humans in the wild, you will generally be very vigilant, because you don't know if the other party will burst out to kill people and seize treasures, but if you meet other humans in the mine, you generally don't care too much, and the purpose of entering the mine is only one, that is, mining, everyone is a miner, mining in the same place, so get along more harmoniously, unless you dig a peerless ore, you have to take it out to show off, and be seen by others......

Xu Feng recalled the years of mining, couldn't help but smile slightly, and walked in the direction where the voice came from.

The monitor lizard beast with a small body shook its head and followed behind Xu Feng, in this small place, even if it encountered a monster, it had no choice but to stare dryly, and let out one or two unthreatening roars towards the monster, so along the way, the monitor lizard beast was in a very bad mood and looked very aggrieved.

Soon, Xu Feng saw that a human being in front of him was in a dark corner, holding a pickaxe in both hands, and smashed it towards the rock wall.

"Hey, brother, what about mining!" Xu Feng raised his hand and said hello.

However, the man didn't seem to hear it, ignored it, and continued to repeat the action of mining.

Xu Feng frowned slightly and walked forward.

Just within ten meters of the man, suddenly the person on the other side stopped mining, held a pickaxe, and turned his head to look at Xu Feng.

"Ho, ho, ho~"

With a hoarse voice and a strange wheezing sound, the man dragged the pickaxe and walked towards Xu Feng, its hind legs seemed to be injured, and it was very stiff to walk, always taking a step with its left leg first, and then dragging its right leg up, and continuing to repeat this walking action.

Seeing the appearance of that person, Xu Feng's eyes became sharp, and he couldn't help but clench the long sword in his hand, and he felt that the atmosphere around him seemed to become strange all of a sudden.
