Near the entrance of the cave filled with black iron is an endless grassland. All kinds of unknown weeds are growing crazily, knee-high, and scattered everywhere. The surface of the huge stones surrounded by lush grass has traces of artificial carvings, as if unknown. The shadows of civilization from so many years ago can still be seen everywhere. "This should be a city!" The information scanned back by the "Eye of the Lich" quickly displayed everything within a radius of thirty kilometers in front of Lin Mo. From the overlooking boulders dotted with stones, it could be vaguely seen that they were neatly arranged. city ??planning. There was a huge ruin not far in front of him. It can be guessed that it was once a very magnificent building. The traces and architectural style of the entire city are completely different from the main city of the Pseudo God Kingdom seen in the past. Instead, it is similar to the surface world, but the planned layout is extremely grand, as if it is a super metropolis with a population of tens of millions. "Lin Mo, come and take a look, we found the fossil of a giant dragon here." At this moment, Li Mubing's voice came from afar. It seemed that the team found something unexpected while setting up camp. Tens of thousands of square meters of grass were burnt black by kerosene, and plant ash turned into fly ash slowly fell from the sky, adding some gray-white embellishments to the ground. When Lin Mo and the giant metal dragon arrived, they saw a large pit dug in the charred ground, just like an archaeological site. More than a dozen people squatted inside, brushing away with brushes, and a large hole appeared at the bottom of the pit. The remains of a huge dragon bone. The dragon scales have long since disappeared, but the dragon claws remain. There is also a dragon crystal that has long lost its elemental energy. It is so gray that the color and elemental classification cannot be seen. The edge of the pit was surrounded by giant dragons. They looked at the bottom of the pit, talking among themselves, and constantly guessing which senior was buried here. "Why are the bones of my clan here?" "Are there any other dragons here?" "It's the predecessor of a fire dragon. Its bones have been somewhat crystallized, and the color of the crystallization looks like red, at least. "It's impossible for such a senior to have fallen outside. It seems like the accumulation on the bones has been there for a long time." Lin Mo saw Li Mubing waving to him, and he walked over and said at the same time, "How could he find the dragon bone?" "It seemed like it had been a long time ago." "While setting fire to the grass, I accidentally discovered a small piece of tail bone exposed on the ground, so I dug down and found this." Li Mubing was also quite surprised by this discovery. , according to the current condition of the bones, a large number of mineral ions have replaced the original calcium molecules. Make the keel extremely dense and hard. "What did the Lord Dragon King say?" Lin Mo looked not far away, the Dragon King Igfisro who had been staring at the scene and remained silent. Li Mubing said: "It can't guess which senior it is?" Lin Mo's heart moved, and he suddenly said: "Let the 'Eye of the Lich' scan to see if there are any other skeletons within a depth of fifty meters!" " What do you mean?" Li Mubing opened his mouth. There seemed to be a big secret behind the other person's idea. "It's just a guess!" Lin Mo shrugged. He had no substantial evidence. Suddenly a giant dragon skeleton fossil was discovered. Even the dragon scales were lost in the years. Even the dragon clan didn¡¯t know its identity. This place where day and night alternate is really full of weirdness. The "Lich Eyes" who received the order centered on the camp. After adjusting the scanning mode, there was a strange vibration sound, and he checked quickly against the ground. Ten minutes later, Li Mubing came back to Lin Mo holding the tablet computer. "You guessed it, there is a cemetery underneath. There are not only dragons, but also humans, demons, and feathers. The bones of all known intelligent races can be found. There are also some intelligent races that do not exist. "The newly scanned underground conditions by the "Eye of the Lich" show very obvious traces of bones. After long-term accumulation of minerals, these fossil bones are very easy to detect. "I don't know if there is any carbon-14 identification equipment. I remember that I got a few through Mahia." Lin Mo was not in a hurry to announce the newly confirmed news. Otherwise it will immediately cause an uproar. "I checked the list. I brought a lot of things this time. Are you saying that these bones are not from the short term, or even earlier than a hundred thousand years ago?" Li Mubing easily caught up with Lin Mo's thoughts, and immediately put it in his mind It was retrieved on the tablet, although everything was placed in the large-capacity space alchemy memory. But there is a complete list in her and her sister's hands, which is very convenient when they want to call it. ??After a while, she said with surprise: "I found it. Sure enough, it's the goods of the Japanese." "It doesn't matter where it comes from, as long as it's useful! Look for the instructions and check the time of the keel!" Lin Mo He babbled at the fossilized dragon bones at the bottom of the pit. "You guess this is the garden of the gods, right?" Li Mubing finally said what Lin Mo had never said clearly. "That's right! That's what I doubt. The large number of skeletons of different races means that many intelligent races once lived here, and the mature and complete urban planning obviously means that many years ago, the wisdom of many surface worlds The race once lived here, and lived here for a long time. "Lin Mo rarely concealed his thoughts in front of the Li sisters. "Well, I'll be right back!" Li Mubing held the tablet and ran straight to the communication ship. After just two steps, he walked back to the pit and shouted to the human race at the bottom of the pit: "Get me a claw or a tooth. That's okay!" "" The human race who was doing the archeology at the bottom of the pit looked at her blankly and didn't react for a while. "Obey the order!" With Lin Mo's words, these humans immediately came to their senses, picked out a big and sharp dragon claw and threw it up. The surrounding giant dragons looked at each other in confusion, wondering what this human race wanted to do. The equipment from the earth has a high degree of automation, especially those made in Japan. After repeating the instructions three times, Li Mubing finally got a relatively accurate data range. After all, this is not a magic spell, but a scientific verification, even if it uses carbon There will be a large error in 14 radioactive isotopes, but this error data is enough for her and Lin Mo. "3.1 million years ago! The error will not exceed 5,000 years." Listening to Li Mubing's age determination, Lin Mo took a breath of air. He originally thought that the "Garden of the Gods" existed for a long time, but he did not expect that it would be so long. To this extent. The equipment left by the god "Qin" may be at least a million years old and can still be used normally. This is not just a miracle, but a miracle. If it were a creation of earth civilization, even if it was left untouched, it would probably break after a thousand years - (To be continued.)
