After reading the intelligence, Li Er couldn't calm down for a long time. Then he made a quick decision and set off to the underground tomorrow. Although there are still 10 days before the auction of the Iron City, there are many things to do this time. These 10 days may not be enough. The next morning, Li Er got up and washed up, and immediately summoned the army. Bring two battalions of cold-blooded cavalry and dark night hunters directly. Because the situation changed too quickly, Li Er summoned the mist shadow that was originally planned to stay in the undead plane to develop. This level 17 special unit has a strategic role, and he uses it very smoothly. As for the flesh and blood slaughterer, he is not worried, just let it develop in the undead plane. With the deepening of the control of the power of authority, the power he left on the flesh and blood slaughterer before also became like a shining star in his eyes.
As long as he wants, he can immediately summon this level 18 divine life from the undead plane as a helper. However, the distance is too far, and this operation may directly cause his soul to be severely damaged, or even die directly. This limitation is also the reason why Lear only anchors the Flesh Slaughterer. The opponent can be resurrected, but ordinary heroes don't have this ability. When you encounter a place where you need to use the opponent, just take action directly. In addition, he also brought 7 big demons promoted to level 16, the level 17 two-headed ogre chieftain, and the level 16 mechanical flying dragon. In this way, the formation of the last expedition has been fully gathered. But after a little thought, Lear decided to bring the scarlet queen bee, plus 15 squadrons of rhino warriors. At the same time, there are 500 cavemen and 30 bubble beasts. The territory is expanding rapidly, and the blacksmith shop is operating at a high intensity every day. The original stored fuel has run out. The magma coal at the exit of the underground passage is a 3-star fuel, which is no less valuable than gold. There was no time before, and if it is not mined now, there will be no chance when the underground world collapses. Under Lear's will, the army quickly gathered, and various military supplies were also moved out of the warehouse. After everything was ready, Li Er did not hesitate and led the army out of the swamp. In the city of Wei Lu, there were 5 squadrons of cold-blooded cavalry, 2 squadrons of night elves, 3 squadrons of dark Naga, plus the 15th-level Naga King and the Goblin God. In addition, 7 squadrons of ancient tree guardians were rooted on the city wall. There were also graveyard guards who could return from the undead plane to provide support at any time. At worst, 6 battalions of two-headed ogres who were working hard in the territory could be pulled out to serve as warriors. The superficial power alone was enough to resist most enemy invasions. Not to mention the hidden power - in the city of Wei Lu covered with vines, the vine fairies who had been promoted to 4 stars were the most terrifying combat power.
They could directly control and connect the entire city. This power was not even inferior to the 19th-level life. Those fist-sized guys were the hidden big bosses of the city of Wei Lu. But that's not all. Lear left a unique power to Bane. If he encounters an invincible situation, he can directly sense it after Bane activates it. At that time, he will mobilize the power of the swamp, tear the space, and return to the swamp. This is the biggest killer. As long as he is in the swamp, anyone who comes is a lamb to be slaughtered. How can mortals spy on the means of the gods. Because of the existence of rhinoceros people, the marching speed is not fast, but the warriors have strong endurance and can march for four or five hours at high intensity without changing their faces. By noon, the army arrived at the underground passage. Looking at the entrance, the vines have woven a small fortress. This was built by Lear after repelling the coalition of the Holy Song Clan last time. Now it's just in time. While Lear was thinking, he waved his hand to let the bee colony guard the entrance to avoid any accidents and someone cutting off the retreat. The black swarm of bees formed a terrifying tide, which made people's scalp numb when seen from a distance. Even the most blind creatures would not encounter this bad luck. After making arrangements, he led the army into the underground passage again. Having had experience once before, Lear was much calmer this time. He sent 7 big demons to explore the way first and eliminate the threats ahead. This underground passage extends down for a hundred miles, winding and rugged, and is not that safe. But in front of the ferocious big demon, the monsters in the passage are no different from weak lambs. Hundreds of monsters were killed directly. The army did not stop for this. On the night of the 20th, the army finally walked out of the underground passage for the second time. Last time, they encountered a bat frenzy at the exit, and the terrifying number made Lear still remember it. Setting foot in the underground world again, it felt completely different. This time the army in his hands was more fierce, and the combat effectiveness of the high-level heroes was incomparable. At the same time, the control of power also made him more calm. No matter what enemy he encountered, he could treat it calmly.
This high-level map could no longer move him. Seeing the dim environment underground again, Lear took a deep breath. He looked up subconsciously, and when he saw the scenery in front of him clearly, his brows furrowed. Two or three thousand meters above the ground, the sky dome rock wall that exuded a faint glow supported the underground world. At this moment, exaggerated cracks appeared. From time to time, large pieces of rubble can be seen falling from the cracks, falling straight to the ground and smashing into the vegetation below. At the same time, at the end of the sight, several underground mountains that are connected to the sky and the ground also have large cracks. It seems to be about to collapse. It gives people invisible pressure. No wonder the underground life is so crazy. The collapse of the underground world has been completely on the surface. Even if ordinary people don’t know the will of the gods, they will be panicked when they see this scene. I’m afraid that the current movement is still small. As the cracks intensify, those underground lives with a little luck in their hearts will fall into despair completely. At that time, it will be the most chaotic moment in the wilderness. Li Er took a deep breath, calmed down his emotions, and immediately came to the place where the magma coal was discovered last time. Before, the bubble beast buried this area with mud. Now it seems that although there are many footprints on it, the mud is still intact. Waved his hand and asked the caveman to start to uncover it. These natural cave creatures, after being armed by the blacksmith shop, all have professional excavation and mining equipment. The efficiency has increased by more than double compared to the previous digging by hand. Each one is like a dog digging a hole, and the speed is very fast. Soon a big pit was dug on the surface. After a brief exploration, 500 cave dwellers led their companions to divide into five teams of 100 people and began to dig separately. Lear did not interfere, leaving professional matters to professionals. These cave creatures immediately worked hard. The soil and stones on the ground were cleared at an exaggerated speed. It didn't take long to dig out magma coal. Seeing large areas of magma coal being mined, Lear felt even more comfortable. This is a 3-star fuel, which contains tremendous energy. After ignition, it can also attract magic power to strengthen the fire, which is a real strategic material.
At this stage, it is a pleasure to get such a vein. Living underground for a long time has allowed cave dwellers to develop their own mining system. The whole process was smooth and Lear felt very pleasant after perceiving it. However, he soon discovered the problem. They needed to carry the mining materials up, which consumed a large part of their energy and prevented them from fully exerting their speed. While thinking, he directly ordered the bubble beast to use bubbles to collect the mined magma coal. When a certain amount is filled, it will rise up and gather together for later processing. In this way, the mining efficiency will increase significantly. Lear looked at the 3-star fuel coming into the account, and his mood improved. He was not in a hurry to leave for the Iron City. After sending the Night Hunters to guard around, he also let the Rhino Man and the Cold-blooded Cavalry participate in the mining. The army's mining is naturally not as professional as the cave dwellers, but the level is high and the strength is sufficient. One force can defeat ten skills, and their own characteristics make up for the shortcomings of technology. No one complained at all. At that moment, thousands of people began to dig the earth frantically. The scene looked very hot. Soon, the magma coal on the ground piled up into a small hill. Seeing this, Li Er immediately asked Bubble Beast to load it with bubbles and transport it back to the territory. In order to speed up the process, the big demon was directly escorted. In this way, the 200-kilometer journey can be completed in two hours, and the round trip takes only four hours. After the second trip, the number of Bubble Beasts directly increased to 60, and the little guys that had been hatched before were also brought over. In this way, 30 Bubble Beasts can be left for mining each time, and the other 30 go back to deliver. Under such high-intensity mining, the efficiency is amazing. But even so, it took a full three days to dig, and it was not until the evening of the 23rd that the mining was completed. Thousands of people, together with the cooperation of Bubble Beasts, worked day and night to dig out large pits underground. The deepest reached 50 meters! Finally, after a brief statistics, Bubble Beasts carried back a total of 60,000 bubbles full of magma coal. The diameter of each bubble is as high as 4 meters. It is full of magma coal. This data is quite exaggerated. According to the estimation of the blacksmith shop, even if the armor is cast with high strength, this batch of fuel can support two to three years! This makes Lear quite happy.
The chaos is coming, and the richer the territory's material reserves, the more confident it will be. The underground world is just beginning now, and the real collapse has not yet come. After the collapse, it will not be calm, but will become more turbulent. The cause of all this is the evil that even the God of Creation cannot kill! No one dares to determine what kind of waves this terrifying existence will cause if it escapes from the seal. After taking this long-discovered mineral vein into his pocket, Lear did not hesitate and asked the rhino man to escort part of the army back to the territory. He planned to travel light this time. The Iron Smelting City he went to this time was the city of gray dwarves. These evil races are not friendly to life on the surface. Bringing too many troops is not conducive to mobility. While thinking, he planned to bring only a few high-level heroes this time. The big demon, the mechanical flying dragon, and the two-headed ogre chieftain. However, just in case, the Shadow of Mist still took in 1,000 cold-blooded cavalrymen and 1,000 dark night hunters into its shadow cage. After the upgrade, the number of people that this fierce life shadow cage can imprison has reached 3 battalions. Enough to accommodate these troops. The strategic significance of the Shadow of Mist is highlighted here. The first time they came to the underground world, the army captured a gray dwarf nearby. At that time, Lear brought him back to the City of Dew, and he is still helping him work in the blacksmith shop. That guy revealed all the information about the underground world. From the information he told, the city hall drew a rough map, which roughly determined the direction of the Iron City. This was enough to determine the direction. After the rhino leader returned with the army, Lear did not hesitate and flew directly into the air. Going straight into the underground. Seven big demons followed with their wings flapping. The two-headed ogre chief and the mechanical flying dragon were also put into the shadow cage by Lear because of their large size and majestic dragon power. In this way, their presence was greatly reduced. For safety reasons, he covered his breath, and the mist shadow emitted a faint black mist, covering most of his figure. Outsiders could only see the blurry face and could not see it clearly. It takes about three days to walk from the exit of the underground passage to the Iron City. The actual distance is about 200 kilometers, not far or near.
Li Er flew directly from the sky and headed towards the target. There is still a week before the dark auction, but arriving a few days in advance can explore more intelligence. The details of the dark auction are of utmost importance, especially the main target this time - the lizard demigod eyeball that can promote the cold-blooded cavalry to a 4-star soldier. Flying in the dim underground world, the scenery on the surface quickly swept behind. In the dim light environment, the vegetation grows very strange and twisted. There is no vitality of the surface plants that grow towards the sun, but there is a kind of dark wind that makes people feel scared. Most of the branches and leaves are distorted and irregular, like dry palms that are wanton and arrogant. The colors are all gray-brown or brown or even black, which looks gray and bumpy, without any bright colors. There is an inexplicable sense of depression in my heart. Living in this environment for a long time, even if there are no enemies, I am afraid that it will become psychologically distorted. Passing through the sky, you can sense the existence of life in the vegetation on the ground from time to time. Some are intelligent races, such as cavemen, underground gnomes, and dark goblins But most are ferocious beasts. Giant rats with fangs, tigers covered with thorns and barbs, and poisonous snakes with seven or eight heads are weird and twisted, without any beauty that normal creatures should have. Lear asked the big demon to capture a few underground gnomes for questioning and determined the direction of the Iron City. The other information, those gnomes are completely blank, and they don’t even know where to run if the sky collapses. Lear can only shake his head and don’t waste time on this. Speed up the pace. The closer you get to the Iron City, the more creatures there are around, and the higher the level is. Even on the way, you can see a few tribes in the underground world, but most of them are empty. It can be clearly felt that everyone is heading towards the Iron City. Finally, after flying for more than two hours, Lear's eyes lit up. At the end of his sight, a very magnificent underground city appeared. It was carved into the mountain, huge and majestic. The top of the city directly led to the sky dome rock wall that supported the entire underground world. Outside, the hundred-meter-high city wall was like a ravine across the earth. A series of ferocious, unique heavy city defense weapons stood on the city wall. Even the high mountains connected to the sky behind were full of city defense weapons.
At first glance, it looked like a super giant hedgehog. Anyone who came to attack would have their teeth broken. On the outskirts of the city, you can see ant-like black spots constantly gathering into the city. It looks prosperous and lively. Is this the Molten Iron City? Lear immediately became energetic.
