Half of the old demon's body slid slowly for more than an hour, and finally came to a wet sandy area. The headless Old Demon moves slowly. If it were a complete Old Demon, it would take five or six minutes to cross this distance. When he came to the sand, Old Demon directly dug the wound on half of his body into the sand. The wound secreted a large amount of fluid, and the wound and the sand were mixed together. Rob was not in a hurry to deal with this half of the earth demon, but looked carefully and saw that the sand stained by the mucus seemed to be slowly melting in the mucus. Suddenly, a dune formed in the sand about ten meters away from where half of the Old Demon was, and then, a complete Old Demon emerged from the sand with its head. The eyes of this earth demon looked in the direction of No. 6 and other constructs. Because No. 6 and others are all lifeless constructs, as long as they stand still, they will not pose a threat. To monsters who have never seen a construct, they are just a lump of iron. So this new earth demon ignored No. 6 and other constructs and focused on half of the earth demon. After a few glances, the new demon's body suddenly shot out. The originally contracted body quickly stretched, supporting its body across the distance of more than ten meters from the air, and bit into half of the demon's body. The mouth full of sharp teeth bit out a big hole in half of the earth demon's body in one go. Only a small part of Earth Demon's body was connected, and it was almost broken into two pieces. The demon will not bleed, and only transparent mucus will flow out from the wounds. Quickly, the demon pushed the huge wound into the sand, and then let the mucus stain the sand and the wound. The headless old demon no longer knows how to dodge or fight back, and can only act based on instinct. The new Earth Demon swallowed the meat in a few mouthfuls and turned his head in the direction of the Earth Demon. Just when the new demon came out of his head and bit half of the demon's body, No. 6 moved and quickly rushed to the side, raising and lowering the knife with his shovel hand. The blade driven by the magic crystal is indeed not something ordinary materials can withstand, given the toughness of the demon's appearance and the strength of its muscles. Ordinary swordsmen may not be able to cut with their fighting spirit, but Rob cut him into two pieces like tofu. The new Earth Demon who lost his head became like half of the Earth Demon, and his wounds were buried in the sand immediately. With the new trophy, Rob no longer needs the half of the earth demon's body. He stabbed it in with the shovel and cut it open to the end. From this half of the body, Rob collected more than thirty demon cores, and several more were bitten off by the new earth demons. After a long time, several more earth devils emerged from the sand. They were three ultra-short earth devils with only five sections and only reached one meter when shrunk. Although their bodies were short, the diameter of their bodies was the same as the previous two earth devils. The devil is almost the same. The huge head is placed on the stubby body, which looks funny no matter how you look at it. Like fat caterpillars, these three ultra-short earth demons arched in front of the injured earth demon and the half earth demon cut into two pieces, opened their mouths and began to bite. Rob didn¡¯t think they were funny at all, and his eyes almost popped out. These three ultra-short earth demons obviously separated from other earth demons and then grew into what they are now. The breeding method of earth demons is probably division and reproduction. If this is the case, cut these earth monsters into several sections, and it is very likely that the broken parts will grow into new earth monsters respectively. In this way, by raising the earth demons, you can continuously breed new earth demons and harvest new magic cores. As long as the scale increases, this will be a very effective method of producing magic crystals. If it can succeed, then Rob will no longer need to worry about the magic crystal. The half of the body of the earth demon that had been dissected out of the magic crystal was left to the short earth devil to gnaw on, while the other long body of the earth devil was cut into five sections by Rob. Even though it was cut so short, the earth demon's body still maintained vitality. Each dug the wound location into the sand, and then secreted mucus. The whole ogre was cut into ten pieces by Rob. Including the original three short ogres, there were a total of 13 ogres on this piece of sand. After a long time, all the gravel that was stuck with the mucus actually melted away, and the wounds formed a ball, gradually weathering out the tough leather. In a day or two, the wound will be completely healed. On the body of the old demon, one of the sections had a crack, and a head was slowly taking shape inside. At this rate, it may only take four or five days for the body of the Earth Demon that has been cut into sections to grow a new head and grow into a complete Earth Demon. In the past half day, the three short-headed devils probably gained a lot of energy from eating the same kind of meat, and two thin bodies grew from their tails, and slowly grew.? is growing. This means that the demons can grow. As long as there is enough food, their growth rate is not slow. When the scale increases, the output of magic crystals will be very high. Sand and food are the elements for the growth and reproduction of earth demons. It seems that I have to re-select a place with a lot of gravel as a breeding ground. Rob asked No. 6 to open the storage compartment in his abdomen and put the detection structure out. It didn't take long to find a suitable place in a nearby low-lying area. It was a drop-shaped cave with a small entrance and a large interior. The distance from the bottom to the top of the cave was at least one hundred meters. The entrance is at the top, and the walls are made of solid rock. The earth demon can move freely in the gravel, but it is impossible to break through the hard rock. Rob spread out the detection constructs and searched a large area but couldn't find any traces of other earth demons. So he called the Intelligent Rat slaves over and used a car to transport the sand to the water drop cave and dump it. Go down. It took half a day to spread a thick layer of gravel, and then Rob threw in all thirteen earth demons one after another. From now on, as long as you put food in from the hole from time to time and kill the earth demon before it grows to a hundred meters long, you can harvest the magic crystal. Fifty-five level four magic crystals, this is what Rob gained from an earth demon. It is really incomprehensible that his body can breed so many magic crystals, but its own strength is so weak. It is really difficult to understand. ¡ ¡ The flat river bed is covered with brown stones, and the air is filled with the smell of rust. This is the iron river bed that the wise rat people say the ores only need to be picked up. Looking at the color of the ore, the iron content here is quite high. Under Rob's control, No. 6 removed the magic crystal furnace from No. 7 and assembled it into one piece. They chose a hard ground and dug a row of ditches on the rocks on the ground. On both sides of the ditch were rectangular inverted ladders. module. The discharge port of the magic crystal furnace is facing the ditch.
