Fan Ganglie looked at the bottomless cliff in front of him, looked at the direction of the footprints, and disappeared at the edge of the cliff. His face changed, "is it..."

    "There are other footprints here. It should have been chased and killed by something. It is estimated that it fell off the cliff." Ye dust mountain glanced at the surrounding environment and said euphemistically.

    Fan Yujing and Li Ying both looked ugly. They worked hard to find them. In the previous battle, fan Ganglie damaged the snake wing Canglong and the blood fox flame tailed beast. If they also fell off the cliff and died, wouldn''t their efforts be in vain?

    Su Ping didn''t speak. His eyes slowly scanned the surrounding environment. The arrangement of scattered footprints on the ground, a few battle marks, as well as the residual red hair and broken bones were all included in the bottom of his eyes.

    He suddenly jumped off the demon skeleton beast, came to the edge of the cliff, fell to the ground and looked into the cliff.

    The reason why he fell on the ground was to prevent being attacked and pushed down the cliff. Although he knew that fan Ganglie and others had no reason to do so, he had a heart to prevent people.

    It was dark inside the cliff, just at night, and the visibility was very low.

    "Do you have a fluorescent stick?" Su Ping asked fan Ganglie and others behind.

    Seeing Su Ping visiting at the edge of the cliff, fan Ganglie and others were embarrassed to continue to sit on the demon skeleton animals and came down one after another. Li Ying said, "yes." he turned out several fluorescent sticks from his backpack and handed them to Su Ping.

    Su Ping unscrewed one and threw it into the cliff.

    The fluorescent stick fell straight down and clearly illuminated the cliff and steep wall along the way. The brown rock wall was extremely rough. Dozens of meters away, Su Ping saw a cluster of fiery red hair flying in the rock crack. It was the hair of the blood fox flame tail. The fluorescent stick continued to fall, skimming over the rough rock wall and shining on some dead rattan plants drilled out of the cracks in the rock wall.

    Suddenly, Su Ping seemed to see a strange object, but the fire was too weak and fell too fast to see clearly.

    He unscrewed and threw down a fluorescent stick, which was still the previous track.

    This time he saw that it was an irregular hard block with dark golden particles embedded in the cliff and rough surface.

    "Is it a gold mine?" Su Ping couldn''t help but be stunned. In this unknown area, no human has ever picked it. It''s not uncommon to find gold mines. This is also the charm of pioneering. I don''t know how many pioneers became rich because they found a gold mine or rare minerals such as uranium.

    Su Ping didn''t expect that he was lucky to meet such a good thing for the first time. He was pleasantly surprised. However, it was too difficult for him to pick it. He needed the help of others.

    Moreover, it is impossible to enjoy it alone. His storage space is too small. If it is really a metal mine, even if it is filled with storage space, the extracted value is not high, so it can only be carried back by pet animals.

    At this time, fan Ganglie picked up a stone and threw it off the cliff. He listened carefully. After a long time, there was no response. His face was ugly. He turned to Li Ying and said, "go down and search with your earthworm. If you find the body, bring it back."

    Li Ying nodded and summoned his earthworm to drill into the rock at the edge of the cliff.

    Although they are the favorite beasts of the rock system, mountain shaking beasts do not have the ability to drill into the earth.

    When Su Ping heard fan Ganglie''s words, his previous surprise suddenly disappeared and he sighed in his heart. In this way, his task will also fail.

    A moment later, Li Ying suddenly opened his eyes and surprised: "the earth earthworm has found the blood fox. It''s still alive!"

    "Hmm?" Su Ping and fan Ganglie were stunned.

    eureka? Still alive?

    With the depth of the cliff, the blood fox flame tailed beast, which has no flying ability, didn''t fall to death?

    Seeing the stunned appearance of several people, Li Ying said with a smile: "the earth earthworm was found in a cave in the cliff, and the blood fox is inside."

    "Cliff cave?" Su Ping looked strange and suddenly thought of some grandpa who had been waiting hard.

    Fan Ganglie was surprised and hurriedly said, "take us there."

    "Well," said Li Ying, "I asked the earthworm to drill the passage."

    Before long, there was an inclined channel under the feet of the people, which was opened up by earthworms melting rocks with body fluid. The people slid down the channel with their arms. At the end of the channel was the cave where the blood fox was waiting.

    After falling into the cave, Su Pingfei quickly looked around and found that it was a cave, just a rock pit with a concavity of four or five meters. The blood fox flame tailed beast was lying in it for cultivation. When he saw several people appear, he immediately stood up and showed an aggressive posture. When he found fan Ganglie and fan Yujing''s familiar faces, his hostility suddenly disappeared, A pair of fox like narrow eyes showed surprise.

    "Finally found you." fan Ganglie couldn''t help smiling. Although he suffered heavy losses, at least the task of this trip was completed.

    The blood fox flame tailed beast lay down in front of fan Ganglie and rubbed it intimately. Although fan Ganglie was not its owner, he would feed and tease it at ordinary times. He was very familiar with it.

    Su Ping was relieved to see that there were only some scars on the blood fox, but it didn''t matter. In this way, his task was completed. Fortunately.

    "There are withered vines here. It is estimated that it jumped here with the help of withered vines to slow down." Ye Chenshan looked at the situation on the concave wall and said suddenly.

    Su Ping thought of the thing he saw protruding from the suspected gold mine. It is estimated that the blood fox slowed down with the help of that thing. He immediately said to Li Ying, "there seems to be a metal mine on it. You ask your earthworm to hit the channel there. Let''s go and have a look."

    "Metal ore?"

    Li Ying was stunned. Fan Ganglie, ye Chenshan and others also cast their eyes. They were stunned. Then their eyes soon showed joy. They all know what it means to explore a metal mine in the crack of the starry sky. Once it is a gold mine, they will make a lot of money!

    "Go and have a look." fan Ganglie hurriedly urged.

    Li Ying was also very excited. He immediately asked his earthworms to open up a channel. They climbed up along the channel. Sure enough, they saw a hard object in the soil with a diameter of seven or eight meters and a width of four or five meters.

    Fan Ganglie pulled out a small instrument from his backpack, scanned and measured the object, and was able to test the gold content inside.

    Others also had such instruments, but they didn''t take them out. They just gathered around fan Ganglie to have a look.

    "Uranium content... 0.002%, gold content 2.902%... Silver content..."

    The content of many elements appeared as a list. When he saw the content of uranium and gold, the smile on fan Ganglie''s face had disappeared and was full of disappointment.

    The content of iron, copper, nickel, vanadium and other metal elements in the back is also very low, and the content on the surface of all elements does not exceed 5%.

    Su Ping glanced at the list on the instrument and felt a little strange. If such a large lump did not contain these elements, what would it be? Just then, the little skeleton at his feet suddenly felt excited, stretched out its claws and stroked the lump of minerals, looking very greedy.

    Su Ping was a little surprised, and then realized that this was probably not a mineral of earth elements, but other unknown minerals, which were useful to undead creatures.

    "Can you identify the system?" Su Ping asked silently.

    The system said, "yes."

    Su Ping was surprised: "what is this?"

    "The identification fee is 100 points of energy per time," said the system.

    Su Ping almost spurted blood. Is there a charge?

    Thinking of his remaining 600 or 700 energy points, he gritted his teeth and paid.

    The system first prompted the energy deduction information, and then said: "this is the dark stone mine, the collection of undead energy, which can extract the dark stone. The dark stone can not only be used for cultivation, but also the currency for trading between the dark world and the dead world."

    "The dark stone?" Su Ping was stunned. "So, is this something similar to the spirit stone?"

    "That''s understandable."

    Su Ping suddenly asked, "can you refine this?"

    "Yes."

    "Really, that''s too exciting..."

    "Refining costs 100 energy."

    “……”
