Warm blood splashed around, forming a puddle on the ground. However, the owner of the qi light stepped on the blood puddle, and like a sharp arrow, it hit the gap opened by the barbarian warrior. The qi light splashed wildly, The barbarians who came up were instantly cut into pieces and then pushed out of the city. The owner of Qi Mang stopped moving, and now everyone could see her figure clearly. Audrey was dressed in armor and had a heroic appearance. The appearance of the city lord boosted the morale on the city wall, and countless soldiers shouted, ¡®Long live the city lord! ' With a tone of voice, he faced the enemy with all his might and quickly pushed down all the barbarians who rushed up the city wall. There was a rapid knocking sound of hollow wooden sticks in the main formation of barbarians outside the city, and the barbarians under the city wall retreated like a tide. ¡ ¡ Today is already the third day of the siege of the city by the barbarian army. There are 50,000 regular troops in Black Iron City, including 20,000 combat troops and 30,000 auxiliary troops. Soldiers are professional soldiers who have been trained for a long time and are well-equipped. They are the main force of the city defense army. The training of auxiliary soldiers is not as good as that of combat soldiers, and their equipment is also slightly lacking. As a supplement to combat soldiers during wartime, their combat effectiveness is not weak. The entire Black Iron City has a registered permanent population of 200,000. Due to the special situation of Black Iron City, the number of people who are not registered is more than twice the number of registered people. In addition to the poor people who go to Black Iron City and the miners in major mining areas, there are also Refugees who fled outside the city came in. At this time, the population of Black Iron City exceeded 700,000. This is a very scary number, especially in the case of war, when the production activities of various living facilities are damaged and restricted. Just meeting the daily needs of 700,000 soldiers and civilians has become a huge burden for Black Iron City officials. . Fifty thousand city defense troops need to defend the city walls and maintain public order, and manpower will soon be insufficient. On the third day of the war, a full five hundred were removed from the eight hundred guards guarding the altar. Less than a day later, another two hundred and fifty soldiers were mobilized. However, all the mages and scholars who were originally surrounding the altar had left as early as the first day of the war. Only fifty soldiers were left on the entire altar. Soldiers guarded. In addition to paying attention to the battle situation outside the city, Rob put more energy on the altar. After seeing the second batch of soldiers being transferred, Rob knew that the time had come. Standing up from the ground, Rob waved his hand and the Cold Steel God of War was taken back to the storage space. Then he turned over from the stairwell and jumped to the first floor. In the center of the room on the first floor, a large hole appeared there. Judging from the freshness of the soil, it was obvious that it had just been excavated in the past few days. Jirasha's head poked out of the hole. The big head was covered with mud, covering it as if it had just emerged from the mud. ?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????In the past few days, Jilasha has been doing his old job. A diagonal passage leading to the underground has been dug long ago, and the soft soil layer is constantly being reinforced to avoid landslides. With Rob¡¯s guidance, the passage led to a tunnel in the shortest distance. This tunnel passed directly above the cave where the altar was located, and was less than three meters away from the upper cave wall. With such a short distance, Gilasa can penetrate it in two or three blows, and then Rob and others can parachute directly from the top of the cave to the top of the guard's head. There is a tall stone tower next to the city lord's palace. The height of this stone tower is the highest in the entire city. It is a magic tower. There is a powerful magic detection device on the top of the tower. It is also the control center for all magic settings in the city. . In the magic tower, each floor is equipped with various magic settings, crystals, and projections that constantly flicker and change, switching back and forth between real-time situations in various locations in the city. The underground is the focus of monitoring. Because of the special circumstances of Black Iron City, the underground mines, tunnels, ground cracks and caves are intricate and full of holes, and it is impossible to seal them all. Therefore, monitoring is the top priority to prevent large enemy forces from sneaking into the city through underground passages. Under heavy monitoring, if the enemy dares to do this, it is tantamount to seeking death. A few earth magicians can collapse a passage, and no matter how powerful the barbarian is, he will only be buried and die. For this kind of large-scale detection, the magic power fluctuations need to penetrate the ground, and the information fed back will not be too detailed. It can only detect the activity of living creatures in that area, and the number is approximate. It is not accurate to determine whether the activity is a human or an animal. Among the countless feedbacks, one piece of information caught the attention of a mage. There were vague traces of biological activity near the altar cave. This kind of mark is too slight, and it is certain that the number is not large, or the size is too small, maybe it is a creature such as a mouse or earthworm. The accuracy of large-scale detectors is too low to tell what the object is. Originally, this kind of trace should be ignored. Even if it is an enemy, one or two enemies will not be able to play any role, but that place is too sensitive.?Above the cave where the altar is located. The altar is the top secret of Black Iron City. Except for the mages and soldiers who participated in the excavation and research work, the rest of the people don't know the existence of the altar at all. Because this kind of ancient ruins is a treasure trove that any force wants to obtain at any cost. If the news is known by other forces, even the royal family of the empire will definitely ask to participate in the excavation. In the end, will Audrey be able to keep the altar? They are all unknowns. And this mage happened to be someone who knew about the existence of the altar. To be cautious, he still reported his discovery. Not long after the report was reported, another wave of detection wave feedback came back. The weak traces of activity at that location had disappeared, leaving only a group of relatively large traces of activity below that position. There were dozens of traces in that group. , but the mage didn't take it to heart at all, because it came from the guards of the altar. The mage pursed his lips and thought in confusion: Could it be that something was wrong? ¡ ¡ Dopp irritably whittled a piece of wood with his long sword. The chipped wood fell into the fire, making crackling and exploding sounds from time to time. The entire Black Iron City was mobilized for war, and his companions were fighting bloody battles and making great achievements, but he stayed in the dark cave to guard a pile of stones. I really didn't know what was precious about this stone, which was engraved with inexplicable patterns. , it can¡¯t be eaten or used. Do you need so many people to guard it? Dopp, who has well-developed limbs, really cannot understand the value of this altar to humans. To him, it is just a pile of immovable stones. No matter what shape it is piled into, it is still a pile of stones. With such a pile of stones, would anyone steal or destroy it? ????????????????????????????????????????? Several sounds were heard from the top of the cave, and then a string of gravel fell from the top like rain.
