Although Wang Chen knew that the life of this group of people was very difficult, he did not expect it to be so difficult.

Under the introduction of the old man named Xie Rong, whose beard and eyebrows were already gray, Wang Chen knew the origin of these people and what kind of life they lived.

Their ancestors were also survivors of an underground vault, but their ancestors survived the war of extermination but were trapped underground for hundreds of years.

If it weren't for the virtuous circularity of the sanctuary and the hunting of underground creatures to feed their hunger, their ancestors would have starved to death, but even then their population has been decreasing, from a few tens of thousands to less than 500.

Their depopulation is caused by attacks by monsters from the underworld, as well as by the fact that some of them are unable to adapt to genetic changes caused by changes in their environment, and die of various and strange diseases.

Luckily, when they fought a group of underground monsters sixty years ago, they gained the friendship of another mineral-feeding, docile evolutionary beast, and with the help of the evolved beast they named "gold-eating beasts", they finally opened a passage back to the surface.

Seeing that they were about to see the light of day again, a nightmare struck, and when they opened the passage, they met the first wolf fox, who was already the first wolf fox of the fifth order evolutionary at that time, and captured these people who had not had time to rejoice.

And in order to be able to completely control them, they destroyed almost all of their daily necessities, and since then they have become the slaves of the previous wolf foxes, specializing in helping the wolf foxes mine the gold mines here.

Although they never gave up the idea of resisting at first, and more than once tried to use the help of the gold-eating beasts to open another way out, without exception, each time the tribesmen were subjected to more cruel punishments, and in order to keep the few remaining clansmen alive, most of them had gradually given up their plans to flee from here.

After all, although the wolf fox was cruel and unkind, everyone no longer worried about food, and after fifty years, their population actually increased to more than 1,000 people, and just when they had become accustomed to the life of mining every day for food, an even more tragic fate befell them.

After Lang Ping usurped the position of the former wolf fox, he increased the exploitation of these people, not only increased the mining task for them, let them mine gold day and night, but also directly reduced the food promised by the former wolf fox by half, and even the remaining half of the food was not distributed on time.

Hunger and fatigue reduced the population of this group to less than 400 in ten years, and the most cruel thing was that 90% of the children born could not be fed due to malnutrition, and if there were another ten years, no, even five years, this group of human beings who had survived the war of extermination would die under Lang Ping's endless greed.

"But now that the king has killed that inhuman creature, we won't have to starve anymore. Is that right? King? Xie Rong looked at Wang Chen cautiously and said, for fear that his own question would anger Wang Chen and invite even more brutal exploitation.

"Don't worry! I won't be as inhuman as Lang Ping, start slowing down the mining of gold today, and then take this opportunity to recover first, I will give you a new mission, and after completing that mission, I will let you return to the surface, but only if you are loyal to me in the future. Wang Chen said with a serious face.

After Xie Rong listened to Wang Chen's words, he couldn't help but burst into tears and said, "If the king allows us to return to the ground, in the future, our Xie clansmen will definitely treat the king with liver and brains." ”

"Don't worry! As long as you don't disobey my orders, you'll soon be able to see the sun outside. Wang Chen smiled

After confirming that it was safe, Wang Chen, accompanied by Xie Rong, went deep underground to visit their dwellings, and their dwellings were really similar to those dwarf dwellings in magical blockbusters, all of which were tall and magnificent, full of furnaces and iron diamonds.

And Wang Chen also saw the gold-eating beasts that helped their closest companions, these big creatures with a height of five or six meters were very similar in appearance to pangolins on the earth, but their claws and scales reflected a luster like gold, and their skin and muscles looked like rocks.

"The gold-eating beasts feed on these gold mines, and after digestion, they will absorb most of the elements in the ore, and then eliminate the elements that cannot be absorbed, because this is a gold mine, so the content of gold in their excrement is extremely high, and more than half of the gold we smelt comes from their excrement." Xie Rong introduced Wang Chen on the side.

After a pause, he continued, "The other half is to rely on their great digging power to obtain ore, and then we smelt gold from these ores. It is only because in the past ten years, with the decline of our people's population, and the hardship of life, it is impossible to provide them with enough urine, and their number has plummeted to less than twenty because of indigestion. ”

Only then did Wang Chen understand why the gold-eating beasts had established friendship with this group of people, it turned out that they had an interdependent relationship with humans; I also understood why the caves here are so tall, and why gold can be mined here, it turns out that all of this is with the help of gold eaters.

"The gold-eating beast feeds on ores, is it all ore?" Wang Chen asked with a move in his heart.

"According to the predecessors, they came to the conclusion that they will feed on metallic ores, but since they have been trapped in this gold mine, I am not sure." Xie Rong said with some embarrassment.

"It's okay, we'll see this later, so I'll put it aside. But you must make sure that these gold-eating beasts survive well, and then breed as many young beasts as possible, and in the future they will surely become the treasures that all the forces are rushing to want. Wang Chen looked at Xie Rong and said solemnly.

If he could breed these gold-eating beasts in large numbers and sell them, even if they could only feed on gold mines, they would be able to sell them for a sky-high price, and if they could really feed on all the metal ores, then he would have to think carefully about selling them, because they were absolutely priceless.

"It's very difficult for them to breed on a large scale, and in the first 50 years, they only bred from four to about 40, and in the past ten years, they have only raised two young animals." Xie Rong said with some embarrassment.

"Huh! It's okay, I'll figure out how to solve this problem, you just need to take good care of the gold-eating beast then. Wang Chen said comfortingly.

With the existence of the Life Source Stone, he didn't worry about the breeding of gold-eating beasts at all, even if he couldn't reproduce quickly and on a large scale, there was absolutely no problem for these twenty-odd gold-eating beasts to give birth to one or two young beasts during the breeding period.
