The light outside the cave gradually dimmed, and at the bottom of the valley below, a large number of mine officials also returned from their labor, and before long, piles of bonfires were lit on the flat mines, and smoke wafted up.

Gu Yi, who was leaning on the iron fence, casually inquired about the information of this world from Niu Dan, and from time to time intentionally or unintentionally glanced outside the animal prison, as if he was looking at the scenery, but in fact he was secretly looking at the surrounding environment.

The entire bluestone mining area is a horseshoe-shaped col, surrounded by mountains one after another, forming a natural valley with a flat valley floor in the middle, which is used as a natural mine for ore stacking.

In the center of the valley is a "hearth" that constantly spews orange-red flames and billowing smoke, to be precise, it should be called "earth fire furnace", which looks like an eruption vent of underground molten lava, but it is actually a man-made smelting facility... I have to say that although the civilization of this world is primitive, it has its own very magical smelting technique.

The ragged miners mined the ore from the mountains, transported it to the mine for stacking, and melted the selected ore into the hearth by manpower, extracted the molten slurry containing metals, and then flowed out of the "fire tunnel" under the hearth, poured into the compacted earthen pools, and waited for it to cool into ingots.

These ingots are not pig iron, but only filter out the non-metallic ingots as much as possible, which belong to the first rough processing of the ore embryo, and are also the only product of the bluestone mine, and the deep processing is not possible in this humble mine, the ore embryo will be sent to other places for the next process of finishing.

The abandoned mine where they are now is on the right side of the "horseshoe", on the top of an abandoned mine hill that has been excavated, from the perspective of Gu Yi, you can directly see the mine camp and mine under the valley floor, a large number of mine subordinates are working, and the sporadic mine guards are carrying the symbol of their power: tung oil iron whip is supervising.

After more than a month of encounters in the mine camp, he almost had a grasp of the general situation of the bluestone mine, which seemed to belong to the fat head and big ears of the fat pig mine, and here, he was a lawless earth emperor, holding the power of life and death of everyone in the entire bluestone mine.

And under his command, there are about a dozen pawns and hundreds of mine guards, who guard the valley mouth, so that the horseshoe-shaped col has become a natural prison, and it is unlikely that they want to break through the valley mouth directly and escape... Especially after Gu Yi really saw the magical "madness" ability possessed by the natives in this world, he knew that the possibility of Lu Dao escaping from the heavily guarded valley mouth was almost zero.

Although the environment of the bluestone mine is simple, the precautions are very strict, most of the hundreds of mine guards are responsible for guarding, and only a few act as overseers, enslaving the mine officials to work hard.

This ghost place is a natural fortress that is easy to defend and difficult to attack, both internally and externally, so if you want to escape, you can only find another way to climb over those mountains, maybe there is a glimmer of life, but judging from the rugged and steep mountains, it is not difficult to climb over those cliffs with your bare hands.

Since there is no hope of "escaping from prison", he can only find another way to escape from here, after experiencing a series of near-death and surviving times such as subsidence, caves, and giant beasts, Gu Yi, who also has some mysterious power, can only pay attention to this so-called "blood cage fighting scene" and "fighting karma", and put it in the place of death and then live, hoping to find a glimmer of life from it.

Gu Yi looked up at the sun on the top of the mountain, estimated the time slightly, and silently calculated in his heart, the length of time in this world seems to be similar to his original world world, even if there is a difference, it will not be too big.

It's just that this world, which is still in the primitive society, generally lacks time measurement tools, so the division of daily time is far less detailed than his original world, only "midnight, wild chicken, dawn, dawn, morning eclipse, sunset, sunset, dusk", these twelve time periods to distinguish.

For the vast majority of ordinary people who earn and rest at sunrise, these twelve periods are cumbersome, and they are only divided into six periods of "morning, morning, noon, day, evening, and night".

When he woke up, it was called "morning" by the natives of this world, about 10:00 in the morning, which was also the time for them to eat brunch, after a fight with the strong man, and a question and answer with Niu Dan, it was almost "dawn" at this moment, that is, around 14:00 in the afternoon.

If the estimate is correct, in a few hours at sunset and dusk, the mine camp will close the camp and put the meal, according to Niu Dan, the mine guards will come to take these "cattle" out of the gang, ready to participate in the "evening" time, every ten days and ten days of "blood cage fighting", through internal struggle to select strong people, so as to participate in the bloodier and extremely high mortality rate of the "fighting caravan".

Before that, he had to figure out the division of power in this world, and at the same time find a corresponding strategy, otherwise he wouldn't know how he died!

After seeing the magical abilities of the natives in this world, Gu Yi's heart is far less contemptuous of these "primitive people" than before, and at the same time, there is no longer an inexplicable "modern superiority".

After all, this is not the ancient world that he is familiar with, but a completely different time and space, and the "sense of superiority" he originally relied on will not play any role in this world world where strength is respected and the social class system is strict to the point of perversion.

Gu Yi, who recognized the facts, understood that if he wanted to live, he could only desperately improve his strength, otherwise in the eyes of those upper-class "primitive people", he, a "modern man", was also just a "dog".

A burst of shouting came from not far from the outside of the cave, and the sound of "jingling bells" came from the collision of iron and stone, as if the "animal prisons" of one cave after another were being opened, and those big men who were the people of the cave were being released.

The light and shadow in front of him dimmed, and with a "bang", a pair of metal shackles were thrown in and landed in front of Gu Yi, which also woke him up and slowly looked up.

I saw a pawn leader leading a group of mine guards, who were looking into the livestock prison in surprise, obviously a little strange that Gu Yi was sitting alone at the entrance of the cave, and when Gu Yi raised his head, the pawn commander roared impatiently: "Where are the people!? Where have they all gone!? What are you looking at? Why don't you get out with the shackles!"

Gu Yi sat behind the iron fence with his knees hugged as if he hadn't heard it, and the struggle in his mind had reached its most intense time at this moment, and the pawn chief saw that there was no reaction in the cave, so he angrily pulled out a thick-backed big knife with a cold light and shimmering, and smashed the thick back of the knife on the thick iron grille at the mouth of the bowl with a "click", and let out a piercing roar: "Do you want Uncle Ben to come in and invite you?" The miners behind him also shouted as if they were cheering.
