When the new year was still two days away, the whole ice city was finally built. This time, Li Yuanhong set up a three-layer wall. The outermost part was still at the mouth of the valley, and many traps were set outside the valley mouth. This time, the traps were all large-scale traps, not the ones that could be filled with dozens of zombies last time. If the zombies really came, each trap would not leave 180 corpses Don't think about it. In addition, on the top of the mountain outside the mouth of the valley, Li Yuanhong also set a lot of rolling stone traps. If the zombie attacked the mountain, he would not climb it as easily as he did last time.

On the second floor, a wall was built two kilometers away from the mouth of the valley. On this wall, dense stone throwing machines were set up. Once the valley mouth was lost and the zombies rushed in, they would face a dense fire attack. This is not the last two tepid attacks, but the attack of dozens of stone throwers. In one round of attack, there will be at least hundreds of zombies Casualties, and the throwing machine is completed every minute. According to the speed of the last zombie attack, when the zombies attack the city, it is very difficult to attack the city without 4000 or 5000 casualties. In addition, from the mouth of the valley to the outer wall, there are a lot of traps. Li Yuanhong gives full play to his trap skills.

The last wall was rebuilt on the basis of the original city wall. This time, it not only increased and widened the wall, but also built a layer of wall inside the wall. In this way, the fragile and non earthquake resistant characteristics of the ice wall can be alleviated. The soil can absorb the vibration and reduce the damage caused by ice breaking.

In addition, the height and width of the inner city walls increased. Li Yuanhong also asked Zhang Haitao to drive down a large number of bows, arrows and spears. During this period, 20 archers and 30 spearmen were produced. Moreover, Li Yuanhong upgraded these taxis to level 3. Among the elite soldiers, there were one or two hundred mutant zombies who attacked the city last time. They were not their opponents at all.

Li Yuanhong thought that the preparation was almost finished, and finally decided to upgrade the council chamber.

On that night, Li Yuanhong informed Li Luoxia to withdraw from the meeting hall. It was certain that when the building was upgraded, there would be no living things in the building.

Li Yuanhong clicks on his watch, clicks on the meeting hall, and then clicks upgrade. The Second Council hall still needs one unit of wood and stone. The demand for steel and copper has increased, both of which are two units. However, there is no increase in other raw materials. However, the crystal nucleus required is not the first-order crystal nucleus, but the first-order and second-order crystal nucleus. The quantity is still 100.

All the raw materials appeared with the runes in the sky, and were involved in the energy flow. It took half an hour for the energy storm to subside. A new building appears in the place of the original Council hall. This time, the building is bigger than before. The building is still like a huge stone pile, but it is much more refined than the first one. The boulder is not as rough as the one that has not been polished. Finally, there are traces of processing.

Step into the first floor, is no longer a meter, but raised to 1.5 meters, let people have the feeling of looking up at the stone gate. On the stone gate, there are a lot of runes painted on it. It's not like the first level. It's just a piece of stone. Finally, it has some decoration. Of course, Li Yuanhong knows that the runes are not runes. Li Yuanhong and Li Luoxia walked into the first floor of the conference hall. The hall was more spacious and there were a lot of runes on the walls around the hall. The long corridors on both sides have been lengthened a lot, and the stone slabs on the ground have been polished.

On the second floor, there are many more rooms, including a combat room and a guard room. In addition, there are also energy rooms and sand table rooms. On the second floor, there is one more floor. It is estimated that the missing bedroom is on the third floor. Li Yuanhong takes Li Luoxia to the third floor. The third floor has also been enlarged, and there are two more rooms, all in the bedroom pattern. However, one is the duty room, which is obviously prepared for the third floor guard.

In addition, there is a guard tower on the third floor. This time, the guard tower is bigger and better protected. Soldiers can choose the size of the attack window according to their needs. In this way, when the enemy attacks, they can close the attack window. In addition, on the guard tower, there is an adjustable platform on which weapons such as bed crossbow can be placed. This platform can be adjusted not only left and right, but also up and down, which can increase the attack field of view of this kind of weapon, so as to provide a wider attack range.

With such protection, Li Yuanhong felt that the assembly hall was more like a fortress. Once the wall was broken, it would provide the final defense.

After reading the whole thing, Li Yuanhong asked Li Luoxia to tidy up the room and arrange for the children to have an early rest. Now that there is a school, there is no longer any saying that they will wake up naturally. As long as the day breaks, these naughty little guys should get up and do morning exercises. Morning exercises are not only about running, but also about Professor Wang Jingrong's Military Boxing. In fact, Li Yuanhong wants the children to learn real martial arts Unfortunately, there is no expert in this field in the camp. Because of the heavy physical exertion such as morning exercise, the kids no longer need to be urged to go to bed. They are sleepy at the end of every day. If not, they will climb to bed.

Li Yuanhong arranged these things and went into the energy room himself. Li Yuanhong wanted to see what new changes had taken place in the energy room after the upgrade. Li Yuanhong was somewhat disappointed by the result. There was no change in the energy room except for an additional energy storage tank. When Li Yuanhong was disappointed, Xiao Yiling flew out.

"Why not?" Xiao Yiling saw Li Yuanhong's mood change."A little bit of it!" Li Yuanhong did not hide it.

"Do you know how much energy can be stored in these five energy storage tanks? Each one is exactly twice as much as before. That is to say, the maximum energy storage capacity of energy storage tanks is 25000 points, and the energy absorbed every day has increased by 500 points to 2500 points. " Xiao Yiling explained.

"Why has the energy storage doubled and the absorbed energy not increased so much?" Li Yuanhong then asked.

"Stupid, didn't I say last time that the energy of nature should be balanced. Excessive absorption will cause energy imbalance. This upgrade will not only increase the area here, but also increase the number of wooden houses outside. That is to say, unfortunately, the area of energy collection will increase, which will lead to the corresponding increase in energy absorption. Otherwise, it will only become higher and larger here, and there will be no increase in energy absorption The quantity of quantity. " Xiao Yiling is a reproach again.

"If you want to develop rapidly, you must find a way to find external energy. I suggest that you collect as much crystal cores as possible. This is the best external energy source. If you can find energy intensive areas, you can also build high-energy collectors." Xiao Yiling added.

"What are energy intensive areas?" Li Yuanhong asked.

"For example, under the ten thousand year ice layer in the north and south poles, it is the place with the strongest ice gas. It is not as good as the 10000 meter trench. It is the place with the most concentrated water elements. On the volcanic island, the fire element is the most dense. The 10000 year forest is the most dense area of wood elements. The 100 meters underground of the Wannian desert center is the most intensive area of soil elements." Xiao Yiling explained.

Li Yuanhong frowned. The places Xiao Yiling said were more dangerous than others, and even whether they could get there. It was estimated that it would be difficult to build energy collectors there. It seems that there is only one channel left to collect the nuclei.

After reading the energy room, Li Yuanhong came to the war room. The war room is a large conference room, but there is also a sand table in the middle of the meeting room. However, the sand table only shows the terrain and the situation of the enemy and our sides. Moreover, we can deduce the effect of the implementation of the enemy's and our strategies on the sand table, with different emphasis on the functions of the sand table room, and the sand table room focuses more on it Monitor all the time.

There is also a specific function of the war room, which is the command system. In the war room, there are a lot of communication equipment. These equipment can be connected with the battlefield equipment outside. The command here can be directly sent to the front line through the communication equipment, but now the communication radius is only 50 km. However, this is also a great progress. In the future, we can arrange personnel on duty in the combat room. In case of any hostile invasion outside, we can inform them at any time.

Li Yuanhong came to the sand table room again. Compared with before, the investigation radius has been expanded to 75 kilometers, which just brings Hunchun city into the investigation radius. Moreover, there are many new icons on the map. After Li Yuanhong points to the sand table room, he finds that they are resource points, including stone mines, wood collection yards, and metal mines such as copper, iron and gold. Li Yuanhong didn't expect that there were so many natural resources here. It seems that he chose the right place.
