In the valley behind the big bamboo peak, there is a mine cave.

It is said that a hundred years ago, there was a commercial town near this mine, and the town was famous for its mines.

The mine produces a variety of black iron and silver ore, and it is said that if you are lucky, you can even dig gold or even amethyst.

Therefore, there is an endless stream of people who come here to pan for gold.

However, later on, I don't know what happened in the mine, many gold diggers went and never returned, and gradually, there were fewer and fewer people in the town, and in the end, it became a deserted place.

Hundreds of years have passed, and the town has long since ceased to exist, replaced by forests and green spaces, leaving only some dilapidated ruins and ruins, telling the glory of the past.

Huo Xiaotian came to the outside of the mine with a hoe and glanced at the mine, and it was dark inside.

Even in broad daylight, it looks a little creepy.

"I'll go, it's not haunted, right?" Huo Xiaotian rubbed his face, stood at the door of the mine, clicked on the Genhard Gate, and took a sip.

With the stimulation of tobacco, Huo Xiaotian pretended to be guts, carried a hoe and walked in.

The mine is in disrepair, coupled with the perennial abandonment, resulting in very turbid gases inside.

From time to time, there was a ticking sound around the mine, which seemed a little weird.

Huo Xiaotian walked a short distance inside, then stopped, put the hoe and pestle on the ground, took a puff of the half-smoked cigarette, and then threw it on the ground and trampled it out.

Huo Xiaotian took a puff of smoke rings, took a deep breath, raised the hoe, and faced the wall of the mine with a hoe.

When the hoe hits the wall. It was not as difficult as Huo Xiaotian expected. But. It was easy to smash down a wall.

It turned out that these places near the entrance of the cave had been dug up by the previous miners, there was no ore in the soil, and the natural hardness was not very strong, Huo Xiaotian went down with a hoe, only dug a pile of sand, and didn't dig anything.

Huo Xiaotian shook his head with a smile and walked inside. When I went down with a hoe, it was still a pile of sand, and I couldn't help but go in again.

Unconsciously, Huo Xiaotian walked deeper and deeper, and he was getting farther and farther away from the entrance of the cave.

When Huo Xiaotian reacted, he found that the entrance of the cave had turned into a small bright spot the size of a thumb.

At this time, a cold wind suddenly blew from nowhere, and Huo Xiaotian suddenly had goosebumps, and his whole body was cold.

"Nima. What the hell is this? Huo Xiaotian scratched his head, although he pretended not to care on the surface. Actually, he was quite scared in his heart.

I felt the smoke again, and was about to light the fire, when suddenly I smelled a strange smell in the air around me.

It's a bit like the smell of rotten eggs, which makes Huo Xiaotian can't help but think of the gas gas in the mine, although he hasn't smelled what the gas smells like, but there is still a bit of common sense about safety, if you light a fire in a mine full of gas, it is tantamount to killing yourself.

Huo Xiaotian hesitated, put the lighter back into his pocket, and put the cigarette in his mouth to his ear.

Huo Xiaotian rubbed his hands, picked up the hoe, and slammed the hoe against the wall.

Just listen to the "Wow! Huo Xiaotian suddenly felt happy in his heart, thinking that his luck was not bad today, if he could dig the mine so quickly, then within a few days, he would almost be able to dig enough iron to make weapons.

Huo Xiaotian went down with a few hoes one after another, only to see that the cave was "banging" and sparkling.

After picking up about dozens of hoes, Huo Xiaotian felt that his arms were a little sore, and his waist was a little tired.

Mining is not a good job, the air is not good, but also super physical effort, even under modern high-tech conditions, mining is not a good errand, don't look at the salary is a lot, but, as soon as you get old, it is a disease of the whole body, the little money you earn when you are young is not enough to pay the hospitalization fee in the future, so, I advise you young brothers, it is not really no way, or don't be a miner, to be honest, the miner is not as good as the courier.

Although the courier is also very hard, but the safety is guaranteed, and the damage to the body is much smaller after all.

Huo Xiaotian rested for a while with his hoe, and then smashed it again for a while, and finally, a piece of ore the size of a watermelon fell from the wall.

Huo Xiaotian picked up the ore, only to see that the ore was black, the surface was very rough, a little red, as if it was blood-red.

Judging from Huo Xiaotian's many years of experience, this red thing should be iron oxide, iron will turn red after oxidation, and copper will turn green after oxidation, which shows that the iron content in this ore is still quite high.

Huo Xiaotian weighed the weight, a piece of iron ore the size of a watermelon weighed more than 30 catties, which further confirmed that this was a piece of iron-rich ore.

Iron-rich ore refers to ore with high iron content, general iron ore, the iron content is only about 40%, and the iron content of hematite and magnetite is the highest, theoretically can reach 70%, but usually iron ore contains impurities, so the actual iron content is about 50% to 65%.

In other words, this piece of iron ore weighing more than 30 catties, the iron content is about more than 10 catties.

Huo Xiaotian put the iron ore into the cloth pocket he carried with him, and after resting for a while, he dug it up again.

In the evening, the sun gradually set, and the sky gradually darkened.

And Huo Xiaotian couldn't feel the changes outside because he was in the pit, he was just bent on mining now, and hurriedly made his magic weapon, so he didn't notice the changes in the sky around him.

By the time he dug down the fifth piece of ore, he realized that the hole had become extremely blurred.

In addition, the cave is terrifyingly quiet, like a cemetery.

Huo Xiaotian couldn't help but swallow his saliva, packed the excavated ore, carried it on his shoulder, and planned to leave.

Huo Xiaotian held a flashlight in one hand and a hoe in the other, and walked towards the outside of the cave.

However, what made Huo Xiaotian very puzzled was that it was clear that the entrance of the cave was ahead, but no matter how he walked, he couldn't get to the entrance of the cave.

After walking around, Huo Xiaotian actually found that he seemed to be spinning in circles.

Huo Xiaotian felt that things were a little weird, in order to confirm his feelings, Huo Xiaotian used stones as marks, and after every distance he walked, Huo Xiaotian left a mark on the wall to verify whether he was going around in circles.

Huo Xiaotian held a stone with a pointed head, and every time he walked a distance, he carved a circle symbol, drawing circles as he walked.

However, as we walked, something even more bizarre happened.

Huo Xiaotian looked at the strange symbols on the wall, and the whole person stayed on the spot. (To be continued.) )
