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

These rocks were eroded by the cold wind and were very fragile, and could be broken with just a little force. Chen Kai and the others needed to spend a lot of effort to completely fix the nails. During this period, large areas of rocks fell from the rock wall with their movements and fell into the bottomless abyss.

Chen Kai is currently in such a rock wall area. He is very careful every time he moves, constantly pulling the rocks with his hands. He continuously uses his power to pull the rocks that are fixed, and then stomps the place where he lands until he confirms that the stone can hold his weight before stepping on it or climbing on it with his hands.

Compared to climbing up or down, it is even more dangerous to climb the weathered rock walls horizontally. Chen Kai has changed directions more than once, trying to bypass the weathered rocks and move towards the target. This seems like a journey of only a few dozen meters, and he has not reached nearly half an hour. His physical strength has been severely consumed during long climbs, and his fingers have worn out a lot of places.

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

"Men! You can't say it's not possible!!" Chen Kai said gritting his teeth, then stretched his fingers towards a stone not far away. "It's still a little bit! It's still a little bit! It's enough... enough! Damn!" As Chen Kai felt angry in his heart, the stone he put on his fingers shattered directly under his force. Looking at the falling shattered rock, Chen Kai felt depressed, because he could almost see what the shadow was.

"I won't believe it!" Looking at the gravel gradually disappeared into the darkness in resentment, Chen Kai slowly took out a chisel from his pocket and chiseled hard towards the rock in front of him. The fine rocks slowly collapsed under the action of the chisel and exposed the solid rocks below. In the end, Chen Kai spent nearly ten minutes to chisel out a place where he could climb with his hands. He grabbed this place and slowly poked his head out, and grabbed the illuminating crystal with his other hand.

"Come here quickly! I found a cave!!!" Chen Kai's voice was filled with joy. There was nothing more to make Chen Kai happy than tossing and hanging on the cliff for most of the day and then finding a cave. You should know that this bare cliff does not grow any valuable herbs, and there is no ore to mine. Apart from the weathered stones, the rest are solid stones.

"What?! We're here!! Ouch!" Everyone stood up from the rock when they heard Chen Kai's words, but because of their eagerness, they almost fell off the rock. Hulans, who was lying on the edge of the rock, had his legs weak at this moment. If Su Xinghe, who was behind him, had pulled him, he would have fallen head-on.

When the sound of dinging and dinging on the spikes sounded, Chen Kai and the others were only less than five meters away from the cave. At this distance, they could see the cave more clearly. At this moment, everyone was excited because they saw a piece of dilapidated section of mine tracks and several scattered human bones scattered on the edge of the cave.

"Ahem!! Pull me!" Guan Yu hung half of his body outside the cave, and then shouted to Chen Kai in front of him. The latter turned around and stretched out his hand and pulled Guan Yu up from below. When Guan Yu stood up straight, the first thing that caught his eye was a faint golden light. The golden light on the rock made everyone a little dizzy. Looking at these ores, Chen Kai suddenly found that it seemed familiar. When he touched the ore, he found that the magic power in his body was uncontrollable, and the magic technique blessed on his eyes disappeared in an instant.

"Yanmo Metal Mine! This is the mine of Yanmo Metal Mine!" Chen Kai immediately conceived the Filin Blood Iron and Silver Light Sejin piled up into ingots in his mind. As players purchase a large number of weapons and supplies in the game, the prices of these two metals are getting higher and higher, let alone the magic metal contained in Yanmo Metal Mine itself.

"Really?" Su Xinghe looked at Chen Kai's eyes that were gradually red. You should know that the price of film blood iron still reaches the terrifying number of 100,000 gold coins per kilogram, and it is still the kind that has no market price. But how big is a kilogram of film blood? It is only half an egg. But soon Chen Kai's eyes no longer turn red. He slowly took back his hand and blessed himself with a firm holy word.

"No! Although these are demon-loving metal ores, they are a little different! What we saw at the beginning was emitting red and silver light, but now these emit golden light." Chen Kai gently tapped with the mine pickaxe, and the solid rock wall made a jingle sound, and the melodious sound conveyed in the air like a graceful bell.

"No matter what color he is! Dig it first!" Guan Yu took out the ore pick and knocked it hard on the rock wall. As a result, he didn't even knock down a piece of ore except for the shocking arm.

"Do you think mining this kind of ore is so simple? It requires a high mining ability to dig!" Chen Kai did not directly wave the pickaxe like Guan Yu. When he was mining the gem abyss in Berkner Town, he learned from those dwarf miners. Some advanced ores are very troublesome to mine. They can be dug out of the veins by brute force. Chen Kai could easily cut the ores with giant swords because they had left the veins, but the ores growing on the veins are connected together, so it is very difficult to mine them.

In the words of the dwarves, mining ores from a complete vein means digging the blood vessels of the earth, just like digging the earth. As natural miners, dwarves will naturally not worry about these, because they will choose to cut off the veins before digging the ore, and only mine the remaining part of the veins instead of mining the entire vein. Because all dwarves believe that the veins will regenerate, and the truncated veins are cancers that need to be removed in the earth. It is precisely through this method that dwarves easily mine precious ores.

However, although Chen Kai knew that dwarves needed to cut off veins when mining precious ores, the problem was that he did not know this method. Even among the dwarves, only dwarves at the level of mining masters would use this method, and there were less than ten mining masters in the entire Black Dwarves clan. However, although Chen Kai did not have the means to cut off veins, it did not mean that he could not mine these ores. After all, these ores were in a mined mined cave. The difficulty of mining was much simpler than that of veins that had not been collected by others.

"Let's check the mine first! Lao Su! Contact Xu Fei to see if you can find information about this mine. If there is a map, it would be even better!" Chen Kai said to the people around him, and then took the lead and walked slowly towards the depths of the mine. The illuminated crystals emitting a glimmer of light have been replaced by torches emitting the flavour of pine oil, because there are not many illuminated crystals in Chen Kai and his friends' backpacks.

"...Damn it! How could this be a dead end!!" Chen Kai felt very depressed at the mineway that had reached the end after walking less than a hundred meters, especially when he checked the rocks, he knew that these rocks were not formed after the collapse of the mineway, but were naturally growing rocks.

"Tell everyone good news! This mine with devil metal is ours!" Chen Kai laughed loudly, but no one listened to his words because everyone knew what the next bad news was.

"As for the bad news, everyone knows! This mine is at the bottom. That is to say, the exit is opposite the cliff! Of course, there may be no exit!" Chen Kai said slowly. If the fact is the former, then Chen Kai and the others may still leave here, but if it is the latter, then Chen Kai and the others will be completely tragic, because if it is the latter, it means that the passage leaving has completely disappeared under the abyss.

"Forget it! No matter whether he is bad news or not! Let's dig first! Money is the most reliable thing to do in your pocket!" Fei Yuan quickly took out the mine pickaxe from his backpack. He had been envious of the ore around him for a long time.

"Yes! Old Su! What do you say there?" Chen Kai slowly took out the mine pick from his backpack, but the next moment he stuffed the mine pick back and turned to the exit of the mine. Because Su Xinghe handed him an electronic map from Xu Fei, looking at the map on the retina, Chen Kai found that there was no difference between such an ancient map and not having it. However, with the help of the map, Chen Kai felt that maybe he and others had a chance to leave, because the mine channels were connected on the map. Of course, Chen Kai could not be sure whether the map given by Xu Fei was the mine map where he was.

"The spear and tinder oil ignite! Well, it shouldn't be blown out!" Chen Kai stood at the exit of the mine. He slowly groped along the broken track and adjusted the direction. After the spear was ignited, the spear in his hand emitted a yellow light. Then Chen Kai threw the spear heavily into the front. The whistling spear dripped an orange-yellow light in the air and then nailed it to the rock wall with a click. Fortunately, the burning flames did not completely extinguish due to the impact. The burning flames attached to the cotton wool attached to the end of the spear were still emitting a glimmer of light. With the help of these lights, Chen Kai could finally use the Hawkeye telescope to check the situation opposite.

"Not here!" Just as Chen Kai put down his telescope, Su Xinghe next to him picked up a spear and threw it out in one direction. Then Chen Kai saw a pitch-black mine cave appearing in his field of view on Chen Kai's telescope.

"At least one hundred meters!" Chen Kai sighed helplessly. There is nothing more painful than seeing the road but being able to see and touch. At this distance, Chen Kai and the others could not use spears to tie ropes to reach the rock opposite. If Donny could still fly at this moment, maybe Chen Kai and the others could easily reach the mine cave opposite, but now Feilong is still receiving treatment in the pet space for more than ten days or half a month. So it means that everyone will be trapped here for at least ten days. Maybe it may be longer.

"This is really not good news!" Looking at the gradually dimming fire 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 the crossbow arrow connecting the rope and insert it into the rock opposite, but now they can only wait for Chen Kai's pet flying dragon to recover, and then fly to the opposite side with the rope.

"Second! Let me tell you good news! Uh! You know? Don't worry, we have found the exit, but the problem is that the exit distance is too far, at least one hundred meters! So we have to stay here for a few days as miners. After Donny recovers, he will pull the rope and we will crawl over and leave this underground world." Chen Kai contacted Xu Fei using the communicator. When he put down the communicator, his ears were full of jingling and knocking on the rock wall.

"Hey! Guan Laoer! Don't dig here! Digging here will make the rock wall collapse! Do you want us to turn into corpses in the mine? Go back! Back!" Chen Kai yelled at Guan Yu who was trying to pick up a cheap one, because the ores behind were very difficult to mine, but Chen Kai didn't want Guan Yu to dig the mine.

"It's okay to dig one piece!" Although he said this, Guan Yu still followed Chen Kai's words and ran back. The torches left in the mine saved the ignition slightly. The lighting time of torches such as oil on the torches can reach a day. However, Chen Kai and the others may not be able to mine 100 kilograms of ore in one day after the torches burned for so long. Compared with other ores, it is more difficult to mine, especially when they are still growing on the ore veins. Although Chen Kai adopted the mining method provided by the dwarves, using flames to burn the ore and then lower the ore temperature with cold water to make it crack, they knocked down a stone weighing less than fifty kilograms in one day.

However, as soon as he became more skilled, the mining speed of Chen Kai and his team began to accelerate, but the food consumption of the group began to become very large. Because the miners were physical labor. Fortunately, Chen Kai and the other five were all melee professions and their strength was very strong. If it were other people, such as Xu Fei and the others, then one hour of ore mining could make the mage's small body exhausted.

The dark miners are uncomfortable in their lives, especially when they consume a lot of food. Chen Kai and his team have to eat at least six meals a day in order to recover their energy. Such food consumption makes the food that could have been a month of large amounts of food consumption, and even more consumed is drinking water. Because mining ores requires water to reduce the high-temperature ore. The surface of its surface is broken due to thermal expansion and contraction, so the original water stored is only enough to drink after calculation, and even taking a bath has become a luxury. How heavy is the body of five men who haven't taken a bath for seven or eight days and are covered in sweat? Chen Kai estimated that at least it can smoke flies and mice to death, and it can also make some animals completely lose their food. In fact, even they themselves have difficulty eating after smelling this smell. The smell of oil stains on their bodies and the lice entrenched on their hair makes the five people look like beggars more than adventurers.

"Boss! There is not much food anymore! And our backpack is almost unable to hold it!" Compared to the harvest of only fifty kilograms of ore at the beginning of the day, Chen Kai and the others were able to dig hundreds of kilograms of ore in the following days. Even though the ore may be less than one kilogram of metal after refining these ores, at least one ton of raw ore accumulated in the backpack of Chen Kai and others in at least a few days. Of course, during the excavation process, Chen Kai and the others also found some condensed metal rough stones. These ores that did not need to be refined were directly thrown into the metal box that was still repairing the armor. After a long repair, Chen Kai and the others had repaired one-third of the two-headed lion armor. The few metal rough stones thrown in should be very rare, especially the golden metal that looked like gold but was several times harder than gold, which Chen Kai had never seen before.

However, this metal rough stone has now disappeared, and it turned into white stone powder to clean it out of the metal box. Looking at the armor gradually recovering from the armor box, Chen Kai was in a good mood. However, the cost of continuing to add magic metal ore is too high. One hundred kilograms of ore can be consumed for three or four days, and only 5% of the armor can be restored. The material wasted is more than more magic crystals. So Chen Kai stopped this wasteful behavior. After all, these magic metals were mined by him hard and could not be wasted in vain.

"Hold on for another day! I just checked Feilong's injuries. He could probably barely fly tomorrow!" Chen Kai wiped the sweat from his forehead, then knocked off the mine pickaxe hard. With a loud cracking sound, he pried off a piece of ore weighing at least half a ton.

"Boss! You are sure there is no secret to mining!" Based on the principle of whom the ore dug belongs to whom, even if there are some big heads left for the team, the remaining ones belong to the individual. The ore dug by Chen Kai is almost half the harvest of others during this period. Of course, Chen Kai's backpack must be able to hold this ore to be considered a harvest. There is no doubt that Chen Kai's backpack space is definitely enough, because many things in his backpack have been cleared into the space ring and space bag. The most important thing is that Chen Kai put most of the food and water into the pet space. In this way, he can free up space to accommodate more ore.

"Of course not! This is a character!!" Chen Kai looked at the ore on the ground and smiled happily. He didn't have any mining tricks on his own. In fact, there is no trick to dig such high-level ore. He either uses brute force or uses thermal expansion and contraction to stay away as Chen Kai said. Of course, the last one is to use high-quality mineral picks. Chen Kai and others do not have high-quality mineral picks in their hands. There are many mineral picks made of stainless steel, but these mineral picks are almost all used and scrapped now.

"Tsk!" Everyone raised their middle fingers at him when they heard Chen Kai's words, and then continued to start their mining journey. When Chen Kai and the others packed the last piece of ore they dug into their backpack, Donny, who had been in the pet space for a long time, appeared in everyone's sight again.

"Little guy! I'm going to bother 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 at Chen Kai with the rope in his arms, then quickly rushed out of the mine and jumped down the abyss. Of course, when it fell, it spread its wings and flapped it quickly. In just a few seconds, his huge body appeared in front of Chen Kai and the others and slowly flew towards the place with dim light not far away.
