At the full moon, the high priest led 100 warriors to the back mountain of the tribe.

"What kind of play are these guys singing? It's not going to be a human sacrifice, is it? Lu Feng said with palpitations.

After walking for about half an hour in the back mountain, everyone came to a large rock, and four guards stood in front of the big rock.

To tell the truth, if it weren't for careful observation, Lu Feng really wouldn't have seen that there was a big stone gate blocked by a boulder on this side of the back mountain, and the mountain road was eighteen bends, which was too cleverly hidden, right?

The High Priest and the two guards chatted briefly, and then the four guards nodded, and slowly pushed the huge stone door open, revealing a huge cave inside.

Under the call of the high priest, everyone began to enter the cave, and after taking a few steps, Lu Feng suddenly felt that the scene in front of him suddenly opened up......

Yes, it can only be described as suddenly enlightened, and it is not an ordinary sudden enlightenment, but a very, very sudden enlightenment!

"The whole back mountain has been completely hollowed out!" Looking at the scene in front of him, Lu Feng was extremely amazed.

Inside this cave, the inner hinterland and space are very huge, and what is even more surprising is that Lu Feng feels different from the primitive tribes outside, and he has entered a new era through that small cave.

Steel furnaces, refining pools, railway tracks, large mine carts, high-tech cranes, iron chains, various types of transporters, heavy aircraft......

"This ...... What's going on?! Lu Feng was a little dumbfounded.

Just now, there was still a primitive tribe outside the door, and now how did he feel that he had suddenly crossed over and entered a high-tech era.

Truckloads of black minerals were pulled out of the deep mines by heavy aircraft, loaded onto waiting trucks, and transported back and forth through the extensive transportation network within the cave.

Lu Feng fixed his eyes and found that the black minerals that had been mined and transported on a large scale seemed to be ......

"Coal!" Lu Feng was surprised in his heart, "Is there a coal vein in this country?" But in the Star God Universe, coal resources are not worth much! ”

"Wait! From the primitive tribes just now, to the current high-tech mining areas, how many lies has been hidden in this country? ”

Lu Feng thought for a while, then picked up a small pebble on the ground, looked at it squarely, and threw it vigorously towards the front tire of one of the transport vehicles.

With a "bang", the tires of the transporter suddenly burst, and the whole car suddenly tilted, which caught the driver off guard, and hit the wrong steering wheel, and with a bang, the whole transporter turned over on its side.

A large pile of ———— Star Source Stones hidden under the coal was poured out with a bang!

The shiny star source stone, the kind of luster that blinds people's eyes, the kind of innocent texture, Lu Feng will never admit it in his life!

That is the Star Source Stone, and under the ground is the Star Source Stone vein!

"The country ...... There is a large area of star source stone veins hidden! Lu Feng muttered to himself in a low voice, his hands shaking involuntarily, it was because he was ———— too excited!

"I-, I'm completely deceived by them, it's so deep, this country actually hides such a huge piece of star source stone veins, and it's still being exploited with all its might, how rich is this!" Lu Feng was so excited that he wanted to jump up and yell, but he still forcibly held back, and he decided to continue to try.

At this time, the overturned transport vehicle caused a commotion, mainly the shiny star source stones exposed after the rollover, which attracted the anger of the guards and overseers.

Several of the guards quickly set up a rectangular reflective rhombus space in the four corners of the car, making it impossible to see the situation inside, isolating the mirror images in the car, especially the exposed star source stones.

Immediately afterwards, an angry aunt, who was supposed to be the head of the overseer or something, was stout, holding a leather whip in her hand, and viciously whipped the "careless" driver.

This Lu Feng finally understood, the original so-called temple refers to the Xingyuan Stone Mining Ground hidden in the back mountain, this huge mining field, the visual military labor population is at least one or two hundred thousand, much more than the people of the primitive tribes outside.

However, the primitive tribes outside are estimated to send a part of the young military labor force here every period of time, such as the group of 100 strong men they are in now, which is estimated to come in for mining.

Soon, the high priest handed over the fresh military labor of 100 men to an overseer, and left alone with the guards.

Under the guidance of the overseer, Lu Feng and the hundred people were probably familiar with some basic rules of the entire mining farm, as well as diet and daily life, military labor distribution, work and rest time, etc.

Lu Feng was arranged to go to the first-line mining area, and with a pickaxe, the shiny star source stone ore body was exposed, which further confirmed the statement that there are star source stone deposits under the vein of this country.

Just don't know if it's a miniature star source stone vein? Or small, medium, large, or extra-large?

Ling Yan deduced that when Zhong Xueqi was anxious to have a male military laborforce, he should have discovered that there were miniature star source stone veins in China, and Lu Feng didn't know what his luck was this time.

But judging from the current mining scale and population, it should be one level higher than Zhong Xueqi, at least it is also ———— small star source stone vein!

After a day of labor, Lu Feng dragged his tired body back to the rest room that had been arranged by the overseer. It's not so much a lounge as it is a stone room with iron rods and stones where slaves are kept, a small room after a small room.

In short, the working environment and conditions here are very bad, once the people of the tribe come in, it is estimated that they will not want to go out again, birth, old age, sickness and death, eating, drinking and Lazar, it is estimated that they have to be solved in this cave, and there is no freedom and their own destiny at all.

As soon as you enter the stone gate, your life is doomed!

"Now that I've figured out the situation here, I can quickly go back to Noah City to prepare! If this battle can take this country and annex its star source stone veins, then it will really make a fortune, a fortune. ”

Just now, Lu Feng also explored the military strength of this mine, and found that the army's combat equipment was indeed relatively high, and the number of people was relatively large, at least much more than the primitive tribes outside. However, it seems that this place is too focused on the mining of star source stones, and the population is all inclined to this aspect, resulting in a military force that is still generally weaker than Noah City.

"Go back and declare war on this country, a quick victory, anyway, my mechanical spider army has increased to 1,800 heads, and it is no longer the strength of the battle in the Religious White City two months ago!"

There was still an hour or so before the cooldown of the King's Star Gate ended, and Lu Feng lay on the stone bed in the stone room, deep in thought.

At this time, there was a violent coughing sound in the stone room opposite, a middle-aged laborer, thin and thin, with tattered clothes, lying on the hospital bed, dying. According to the old workers, many workers here are often sick and seriously ill because of poor living conditions and overwork.
