"I'll go over there!" Seeing the faint shadow, Chen Kai slowly tied a rope to himself, and then tied the rope to the steel nail nailed to the rock wall and began to climb slowly. In fact, there was a reason why Chen Kai was in a hurry to find the entrance to the cave, because the higher the weathering of the rock would be, as he continued to climb up.

These rocks are so fragile that they can be broken with a little force. Chen Kai: It took a lot of effort for them to fix the spikes completely, and during this time, large swaths of rocks fell from the rock wall with their movements, falling into an abyss with no bottom in sight.

Chen Kai was in such a rock wall area at the moment, and he was very careful every time he moved, constantly pulling those rocks with his hands. Continued bursts of force tugged at the rocks that held him in place, then stomped hard with his feet until he was sure that the rocks could hold his weight before stepping on them or climbing them with his hands.

Lateral climbing of weathered rock walls is more dangerous than climbing up or down. Chen Kai had already changed directions more than once, trying to move around the weathered rocks towards the target. It seemed like a few dozen meters away, and it took him nearly half an hour to get there. The body lì was strictly consumed during the long climbing, and the fingers were worn out in many places.

"Boss! Can you do it? Fei Yuan stood on the stone platform, and his voice was very clear on the empty cliff, and it reached Chen Kai's ears word for word.

"Man! Can't say no!! Chen Kai gritted his teeth and said, and then his fingers stretched out little by little towards a stone not far away. It's not close! It's not close! Reach... Enough! Damn it! With a burst of anger in Chen Kai's heart, the stone that his finger touched was directly shattered under his force. Looking at the falling shattered rock, Chen Kai's face was depressed for a while, because he could almost see what the shadow was.

"I don't believe it!" Looking at the rubble that gradually disappeared into the darkness with resentment, Chen Kai slowly took out a chisel from his pocket. He chiseled hard into the rock in front of him, and the fine pieces of rock slowly collapsed under the action of the chisel and exposed the solid rock below. In the end, it took Chen Kai nearly ten minutes to carve out a place that could be climbed with his hands, grasping this place, Chen Kai slowly poked his head out. The other hand gripped the glowing light hedron in his hand.

"Hurry up! I found a cave!! Chen Kai's voice was full of joy, there was nothing that made Chen Kai happier than tossing and hanging on a cliff for most of the day and then finding a cave. You must know that this bare cliff does not grow any valuable herbs, and there is no ore to be mined, except for weathered stones, all that remains is solid stone.

"What?! Here we go!! Ouch! Hearing Chen Kai's words, everyone immediately stood up from the rock, but because of his eagerness, he almost fell off the rock, and Hu Lansi, who was lying on the edge of the rock, was already weak at this moment, if it wasn't for Su Xinghe behind him to pull him, he would have fallen headlong now.

When the sound of clanging bells and banging on nails sounded, Chen Kai and the others were only less than five meters away from the cave. From this distance, they could see the cave more clearly, and at this moment there was a sense of excitement in everyone, as they saw a dilapidated section of the railroad tracks exposed in the mine and a few scattered human bones scattered around the edge of the cave.

"Ahem!! Pull me up! Half of Guan Yu's body hung outside the cave. Then he shouted to Chen Kai in front of him, who turned around and stretched out his hand and dragged Guan Yu up from below. When Guan Yu stood up straight, the first thing that caught his eye was a faint golden light, and the golden light dotted on the rock made everyone a little dizzy. Looking at these ores, Chen Kai suddenly found that they seemed to be a little familiar, and when he touched his hand to the ores, he found that the magic power in his body was uncontrollable, and the magic blessing on his eyes disappeared in an instant.

"Demon Weary! This is the pit of the Demon Misanthropy Metal Mine! Thinking of this, Chen Kai immediately conceived in his mind the piles of Filin Blood Iron and Silver Light Serkin, and as players bought a large number of weapons and materials in the game, the price of these two metals became higher and higher, not to mention the demonic metal contained in the Demon Misanthropy Metal Ore itself.

"Really?" Su Xinghe looked at Chen Kai's gradually reddening eyes. You must know that the price of film blood iron has still reached the terrifying figure of 100,000 gold coins per kilogram, and it is still the kind that has no price. But how big is a kilogram of film blood, only the size of half an egg. But soon Chen Kai's eyes were no longer red, he slowly withdrew his hand and blessed himself with a firm holy word.

"That's not right! Although these are demonic metal ores. But it's a little different! What we saw at first was red and silver, but now it is golden. Chen Kai lightly struck with a pickaxe, and the solid rock wall made a clanging sound, and the melodious sound was transmitted in the air like a beautiful bell.

"Whatever color he is! Dig it first! Guan Yu took out the mine pickaxe very directly and slammed it the rock wall. As a result, except for Zhen's arm numbness, he didn't even knock down a piece of ore.

"You think mining this ore is that simple? It takes a lot of mining power to dig it! "Chen Kai didn't dig directly with a pickaxe like Guan Yu, he had learned from those dwarven miners when he was mining the gem abyss in Burkner Town. Some of the higher ores are very cumbersome to mine, and they cannot be dug out of the veins by brute force. At the beginning, Chen Kai could easily cut through the ores that had come down with a giant sword, because they had already left the ore veins. However, the ore that grows on the vein is connected by the entire vein, and it is very difficult to mine it.

In the words of the dwarves, mining ore from a complete vein is just as much as digging the veins of the earth, and it is against the earth. Dwarves are natural miners who do not worry about this, as they will selectively cut off the veins before mining the ore, and only exploit the surplus part of the vein instead of mining the entire vein. Because all dwarves believe that veins can regenerate, and the severed veins are part of the earth that needs to be removed, and it is in this way that the dwarves can easily mine the precious ore.

It's just that although Chen Kai knows that the dwarves need to use the means of cutting off the ore veins to mine precious ores, the problem is that he doesn't know this method. Even among the dwarves, only the dwarves at the level of mining masters will use this method, and there are less than ten mining masters in the entire black dwarf clan. However, although Chen Kai does not know the means to cut off the ore veins, it does not mean that he has no way to mine these ores. After all, the ore is in a cave that has already been mined, and the difficulty of mining is much easier than that of the ore veins that have not been collected.

"Let's check the mine first! Old Sue! Please contact Xu Fei. Let's see if we can find any information about this mine, and even better if we have a map! Chen Kai said to the people around him, and then took the lead and slowly walked towards the depths of the mine. The lighting spars that emitted a glimmer of light had been replaced by torches that smelled of pine oil at the moment, because Chen Kai didn't have many lighting spars in their backpacks.

“… Damn it! How is this a dead end!! Chen Kai looked at the mine road that was less than 100 meters ahead and felt very depressed, especially when he checked the rocks and knew that these rocks were not formed after the collapse of the mine road, but naturally grown rocks.

"Good news to everyone! This cavern with demonic metal is ours! Chen Kai smiled, but no one listened to his words, because everyone knew what the next bad news was.

"As for the bad news, everyone knows it! This mine is at the bottom, which means the exit is on the opposite side of the cliff! Of course, there may be no more outlets! Chen Kai said slowly, if the truth is still the former, then Chen Kai and the others still have the possibility of leaving here. But if it is the latter, then Chen Kai and they will be completely tragic, because if it is the latter, it means that the passage they left has completely disappeared under the abyss.

"Forget it! Regardless of whether he is bad news or not! Let's mine first! Money is the most reliable when it goes to your pocket! Fei Yuan quickly took out the ore pickaxe from his backpack, he had been coveting the ore around him for a long time.

"Yes! Old Sue! What did Xu Fei say there? Chen Kai slowly took out the mine pickaxe from his backpack, but the next moment he stuffed the mine pick back and walked to the exit of the mine instead. Because Su Xinghe handed him an electronic map from Xu Fei, looking at the map on the retina, Chen Kai found that there was really no difference between this kind of ancient map and whether it was there or not. However, with the help of the map, Chen Kai felt that maybe he and the others still had a chance to leave, because the mines were connected on the map, of course, Chen Kai was not sure whether the map Xu Fei gave him was the map of the mine where he was.

"Spear and fire oil to ignite! Well, it shouldn't be blown out! Chen Kai stood at the exit of the mine. He slowly groped his way along the broken track and then adjusted his direction, the spear in his hand glowing yellow as it was ignited. Then Chen Kai threw the spear in front of him, and the whistling spear slashed through the air with an orange light and shadow, and then clicked and nailed to the rock wall. Fortunately, the burning flame was not completely extinguished by the impact, and the flame that burned on the cotton wool attached to the end of the gun still emitted a faint light. With the help of these lights, Chen Kai could finally use the Eagle Eye Telescope to see the situation on the other side.

"Not here!" Just as Chen Kai put down the binoculars, Su Xinghe beside him picked up a spear and threw it in one direction, and then Chen Kai's telescope saw a pitch-black mine hole appear in his field of vision.

"At least a hundred meters!" Chen Kai sighed helplessly, there is nothing more painful than seeing the way of life but only being able to see it but not touch it. At this distance, Chen Kai and the others had no way to use the spear binding rope to reach the opposite rock. If Donnie was still able to fly at the moment, then maybe Chen Kai and they could easily reach the mine on the opposite side, but now the flying dragon was still being treated in the pet space, and it was impossible to be cured without ten days and half a month. So that means they're going to be stuck here for at least ten days, maybe even longer.

"That's not good news!" Look at the light of the fire that is fading in the distance. Everyone sighed helplessly. If Fei Yun's heavy crossbow was there at this moment, then maybe they could use the heavy crossbow to shoot crossbow arrows connected to the rope and stick them in the opposite rock, but for now they could only wait for Chen Kai's pet flying dragon to recover his health, and then fly to the opposite side with the rope.

"Dick! Good news for you! Forehead! You got it? Rest assured that we have found the exit, but the problem is that the exit is too far away, at least a hundred meters away! So we're going to stay here for a few days as miners, and when Donnie recovers, let him pull the rope and we'll be able to crawl over and get out of this underground world. Chen Kai used the communicator to contact Xu Fei, and when he put down the communicator, his ears were full of the sound of clanging and knocking on the rock wall.

"Hey, hey! Guan Lao Di! Don't dig here! Digging here will knock the rock wall apart! Do you want us to be dead bodies in the mines? Go to the back! Behind! Chen Kai yelled at Guan Yu, who was trying to pick up the bargain, because the ore behind it was very difficult to mine, but Chen Kai didn't want Guan Yu to dig the mine hole.

"Dig a piece and it's fine!" Although it is said so on the mouth. But Guan Yu still listened to Chen Kai's words and ran towards the back. The remaining torches in the cave allowed the group to save a little bit on the cost of igniting torches, and by adding oil to the torches, these torches could be lit for up to a day. But the torches burned for so long, Chen Kai and the others may not be able to mine a hundred kilograms of ore in a day. Demonic metal ores are more difficult to mine than other ores, especially if they are still growing on ore veins. Although Chen Kai used the mining method provided by the dwarves, using flames to burn the ore and then using cold water to lower the temperature of the ore to make it crack, at the end of the day they knocked down a stone weighing less than 50 kilograms.

However, after gradually becoming proficient, Chen Kai and their mining speed began to speed up, but the food consumption of the group began to become very large. Because miners are a piece of labor, fortunately, Chen Kai and the five of them are all melee professions, and their own strength is very strong. If it were someone else, such as Xu Fei, and other spellcasters. Then an hour of ore digging can make the mage's small body tired and paralyzed.

Life as a miner in the dark was uncomfortable, especially when food was consumed in large quantities, and Chen Kai had to eat at least six meals a day in order to recover. This kind of food consumption makes a large amount of food that could have lasted a month, and the consumption is even greater than drinking water. Because mining ore requires water to reduce the high temperature of the ore, so that its surface is broken due to thermal expansion and contraction, so the water that was originally stored is only enough to drink after calculation, and even bathing has become a luxury. How heavy is the smell of five big men who haven't taken a bath for seven or eight days and are covered in sweat, Chen Kai estimates that at least they can smoke flies and rats to death, and it can also make some animals completely lose their desire to eat them. In fact, even they themselves had a hard time craving to eat after smelling it, and the smell of oil, sweat, and lice in their hair made the five of them look more like beggars than adventurers.

"Boss! Food is running out already! And our backpacks are running out of fit! "Compared to the very first day, there was only 50 kilograms of ore harvested. In the following days, Chen Kai and the others were basically able to dig up hundreds of kilograms of ore. Even if the associated metals of these ores may be less than a kilogram after refining, at least Chen Kai and others have accumulated at least one ton of raw ore in their backpacks for at least a few days. Of course, in the process of excavation, Chen Kai and the others also found some condensed metal rough stones, which did not need to be refined to achieve very high purity, and were directly thrown by Chen Kai into the metal box that was still repairing the armor. After a long period of restoration, one-third of Chen Kai's double-headed lion armor has been repaired. The few rough metal stones thrown in should be very rare. Especially the golden metal that looked like it was gold, but they didn't know that it was several times harder than gold, and it was something that Chen Kai had never seen before.

However, this rough metal stone has now disappeared, turning into white stone dust and cleaning it out of the metal box. Looking at the armor gradually recovering in the armor box, Chen Kai's mood was quite good. It's just that the cost of continuing to add the Demonic Metal Ore is too high, and it takes three or four days for a hundred kilograms of ore to be consumed. Moreover, it can only restore five percent of the armor, wasting more materials and consuming more magic crystals. So Chen Kai stopped this wasteful behavior, after all, these demon-weary metals were mined by his hard work and could not be wasted in vain.

"Hold on one more day! I've just checked the Wyvern's injuries, and he'll probably be able to barely fly tomorrow! Chen Kai wiped the sweat from his forehead. Then he knocked down the ore pickaxe with great force, and with a loud cracking sound, a piece of ore weighing at least half a ton was directly pried off by him.

"Boss! Are you sure you don't have a secret mining know-how! "In line with the principle of distribution according to the work of whoever digs the ore, even if some of it has to be handed over to the team, the rest of the bulk still belongs to the individual. The ore that Chen Kai dug up is almost equal to half of the harvest of others during this time, and of course, Chen Kai's backpack must be able to hold this ore in order to be considered a harvest. There is no doubt that Chen Kai's backpack space is absolutely sufficient, because many things in his backpack have been cleared into the space ring and space bag. The most important thing is that Chen Kai puts most of the food and water into the pet space, so that he can free up space for more ore.

"Of course not! It's character!! Chen Kai looked at the ore on the ground and smiled very happily, he didn't have any mining tricks, in fact, there was no trick to digging this high-grade ore, either using brute force or using thermal expansion and cold contraction as Chen Kai said, of course, the last one was to use high-quality ore picks. Chen Kai: They don't have high-quality pickaxes in their hands, but there are a lot of steel pickaxes, but almost all of them are scrapped now.

"Cut!" Everyone raised their middle fingers directly at Chen Kai when they heard his words, and then continued to start their mining journey. When Chen Kai and the others packed the last piece of ore they dug up and stuffed it into their backpacks, Donnie, who had been in the pet space for a long time, reappeared in everyone's field of vision.

"Little one! I'm going to trouble you again this time! Chen Kai handed a tied rope to Donnie and asked him to hold it in his mouth. The little guy nodded to Chen Kai with the rope in his mouth, and then quickly rushed out of the mine and jumped down to the abyss. Of course, when it fell, it spread its wings and flapped quickly, and only a few seconds later, his huge body appeared in front of Chen Kai and them, and slowly flew towards the place that emitted a faint light not far away.

"Which of you goes first!" Chen Kai looked at Fei Yuan and Hu Lansi, because it was Donnie pulling the rope on the other side, the body of the person who climbed over couldn't be too heavy. There is no doubt that Chen Kai is absolutely out of play, and Su Xinghe and Guan Yu are both burly ones who are also out of play, and in the end, Hu Lansi and Fei Yuan, who are relatively slim, have become the only two candidates to climb the rope. (To be continued......)
