Mining has proven to be very hard for Omori. This was not easy for a person who had no prior knowledge of mining.

The Little Spirit Fox had sharp claws and could quickly obtain large amounts of ores. However, it would also lose a portion of her loyalty to Mcgee.

If it was a slave, this concern would not be a problem.

In the future, Mcgee would also have a very stable income from iron and copper mines.

Mcgee did not have to worry about Omori defending betraying him. With the punishment of the contract, no one would be able to go against the power of the system's rules. He only needed to give the other party enough food and water.

However, even if a person took a tool, it would not be able to compare to the Little Spirit Fox's efficiency.

Moreover, Omori's specialty was speed, not strength. With his ability, it was already considered pretty good if he could dig up ten ores in an hour.

Digging up fifteen copper ores in a day was an impossible task.

Mcgee also deliberately did this.

The desire to survive forced humans to move forward.

Once Omori had no choice, he could only beg or work harder for his food.

Mcgee would not let him eat his fill easily. When he was full, he would think of something, and he would not let him starve. That was because when he was hungry, he would not have the energy to do anything, and when that time came, he would rebel.

Therefore, after two hours of chores, he asked the Steel Fairy to rush to the Rift Valley to help Omori.

In fact, Omori went to the Rift Valley that Mcgee had instructed. After looking at the empty scene, just as Mcgee had expected, he had a feeling that he had no idea where to start.

How could he find copper mines in such a big place?

Things like mineral veins were connected underground.

What kind of mine would a pickaxe lead to? What kind of mines would there be in the vicinity.

Those who did not understand could only try one area at a time to see what kind of ores could be dugout.

This method was extremely clumsy. Not only would it consume a lot of time, but it would also consume a lot of the pickaxe's durability.

In his hand, the black iron pickaxe only had a durability of 100, while Mcgee's target was 15 copper ores.

Omori did a test. When he obtained a raw iron ore stone, the pickaxe also showed that it had 99 levels of durability left.

This meant that if one durability was equal to one raw stone, every time he obtained six raw stones, one of them had to be copper ore raw stone.

Otherwise, he would not be able to complete his mission today.

"This is troublesome..."

He frowned, feeling that this task was not that easy.

Just as he was in a dilemma, the Steel Fairy slowly flew over with a big sweet potato in her left hand and a piece of barbecued meat in her right hand.

She hummed a song that she did not understand and approached him. She raised the hand that was holding the sweet potato and pointed at him, then at herself.

Omori was stunned for a moment. "Do you want me to follow you?"

The Steel Fairy nodded and walked deeper into the Rift Valley.

Omori quickly followed and carefully observed their surroundings.

The Rift Valley was filled with danger. The giant pythons that Mcgee had killed were just creatures on the periphery.

Omori, who often roamed the outside world, naturally knew the dangers of this place.

Fortunately, they did not encounter any creatures along the way.

The Steel Fairy finally pointed to a place.

It was a big rock that protruded out of the mine.

What was even stranger was that this big rock was full of cracks, as if it had been pieced together.

Omori hesitated for a moment, but in the end, he chose to believe the Steel Fairy's judgment. So he picked up the pickaxe and started working.

However, something strange happened.

The rock seemed to be very hard. The black-iron pickaxe could only leave faint marks on it.

Although it was full of cracks, no matter how hard Omori tried, he could not pry the piece of broken rock off the rock.

"What's going on?"

Omori was stunned. Were the tools he had not strong enough to mind here?

Just as he was about to ask the Steel Fairy to help him find another place, something strange happened!

A slight tremor came from under his feet and gradually spread. It became more and more violent as it spread. Soon, it affected the entire mine, causing his body to fall to the side involuntarily.

Crack!

The crisp and subtle sound was not obvious, but it seemed to be ringing in Omori's heart.

He looked at the big rock in panic and suddenly realized that the 'rock' had actually stood up!

Pieces of debris fell down continuously as it moved, and dust covered half of the mine.

That nearly three-meter-tall tall and sturdy body gave off an aura that warned people from entering.

It slowly turned its head. There were no eyeballs in its empty eye sockets, but it locked onto Omori in an instant.

Run!

This was the only thought left in Omori's mind.

This was a monster that was at least level-5 and above. It was definitely not an existence that he could deal with.

However, just as he was about to escape, a figure had already flown out of the mine ahead of him.

It was the Steel Fairy. She was timid. When the Giant Rock Monster's attention was on Omori, she abandoned the slave that her master had just taken in without saying a word.

The Giant Rock Monster's big hand tried to block it, but the Steel Fairy was very agile. She easily dodged its attack and disappeared in the direction of the cave.

The Giant Rock Monster roared angrily. It was obviously very angry. Naturally, it would not let another intruder go.

Omori wanted to cry, but he had no tears. He could only brace himself and run deeper into the dangerous mine.
