After listening to Li Yuanhong's words, Li Zhizhong was really excited and cursed: "Jin Shanping, this bastard, was the first one to run away with his men before the zombie came. He also took most of the vehicles and materials with him. How can the remaining survivors run past those zombies and complete more than 10000 people? That's it With that, Li Zhiyuan's eyes turned red. If he had not pressed his emotions, he would have shed tears in front of Li Yuanhong.

Li Yuanhong did not immediately answer the question, but also pondered for a long time, and then said, "Jin Shanping is such a villain. If you see him in the future, don't be merciful." After that, Li Yuanhong stood up, walked up to Li Zhizhong, patted him on the shoulder, and then said, "cherish your current staff. These talents are the cornerstone of your development."

Li Zhizhong nodded fiercely: "well, I remember it!"

Li Yuanhong turned and walked out. Since he knew that jinshanping was not dead, Li Yuanhong didn't need to stay. Now Li Yuanhong has no time to waste. Now it's March. If you put it in the pass, the ice and snow will melt. Now there is not much time left for him. Li Yuanhong must seize the last moment of ice melting to complete his base construction plan. Otherwise, when the ice wall fails, Li Yuanhong will not dare to invite zombies to besiege the city.

Back at the canyon base, Li Yuanhong began to prepare for the upgrade plan. In fact, the upgrade materials were already ready, but Li Yuanhong did not dare to upgrade. After all, the zombie siege was the trouble. Now that the surrounding zombies are basically cleaned up, Li Yuanhong has no worries.

At midnight, Li Yuanhong stood outside the conference hall. This was the first time Li Yuanhong took Li Luoxia to visit the upgrading process. With Li Yuanhong's instructions, the assembly hall was again covered by the magic energy storm, which lasted for ten minutes before it stopped. Li Yuanhong was stunned when he saw the new meeting hall. The reason is that the meeting hall has not changed. It is still four floors, but it looks more mysterious outside. Li Yuanhong is a little strange. The building has been upgraded. How can its appearance remain unchanged?

So Li Yuanhong took Li Luoxia into the conference hall, but the interior layout was still the same, but the fantasy color was more obvious, but the internal layout did not change. Until the third floor, it was found that the sand table room and the strategic command room were different. The investigation scope here was enlarged, and the sand table room was not only expanded, but also many signs were added. Li Yuanhong opened a certain sign and unexpectedly But it's a mineral mark. Li Yuanhong realized that there were so many minerals around him, including not only iron ore, logging and quarries, but also many rare mines such as coal mines and gold mines. This was a great gift. He could mine these minerals as long as he had enough manpower.

In addition, Li Yuanhong found that the energy of the energy room has also increased, but since the establishment of the energy room, there is no other consumption except daily consumption, so Li Yuanhong does not know what the use of these energy is. But what the system gives you, it must be very useful. It's just that I haven't discovered it yet.

But these changes are all natural upgrades. Where have the extra materials gone? Li Yuanhong could only run to the fourth floor to find out if there was any change. However, Li Luoxia was still careful and found a special Rune behind a decorative painting that had not been seen before. When Li Yuanhong touched the rune, the rune opened a door, and behind the door was an elevator. Li Yuanhong takes Li Luoxia into the elevator. There are only two choices for the elevator, one is the fourth floor, and the other is the negative floor. Li Yuanhong can only choose the negative floor. After selection, the elevator door closes again, and the elevator starts. This elevator is completely different from the elevator on earth. It doesn't feel the sliding sound of the machine at all. Instead, it looks like an air bag floating in the water. Maybe this is the application of magic rune.

Soon the elevator reached the bottom, and the elevator door opened. Li Yuanhong took the lead to walk out of the elevator door. There was a large hall outside the elevator door. There were many rooms on both sides of the hall. Each room had signs. There were storage room, storage room, monitoring room, bedroom and many other functional rooms. Obviously, it was an underground refuge. In addition, there is a tunnel leading to the distance, this tunnel is very wide, can directly side by side with two large trucks, absolutely no problem. Li Yuanhong walked along the tunnel for nearly ten kilometers until he came to the end. There was still a stone wall at the end of the tunnel. There were many runes on the stone wall. Li Yuanhong, who had experience once, put his hand on the stone gate and quickly flashed by. The stone door opened quietly, revealing an elevator. Li Yuanhong entered the elevator, and there were two elevator buttons, One is the negative layer, and the other is one.

After Li Yuanhong selected a floor, the elevator went up quickly and stopped. The door at the exit opened. Li Yuanhong found himself in a dark cave. Li Yuanhong opened his flashlight and walked along the cave. Soon he came to the entrance of the cave. He found that this place was in a cave on the back of the base. Li Yuanhong had been here for defense When I visited the back mountain, I still had some impression. I didn't expect that there was an escape tunnel in my underground refuge. It seems that this system is more and more in line with my personality. I even prepared myself for the way to escape in advance.

Li Yuanhong went back to his room in the Council hall and suddenly realized that he had been paying attention to the buildings on the ground surface, but neglected the underground protection system. If the underground protection system was connected, like in the tunnel war, he could not only hide, but also effectively attack the enemy's attack. Why didn't he think of such a thing before? Fortunately, when we upgraded the assembly hall, we found some shelters at the bottom, and then we remembered this kind of defensive warfare. It seems that we should establish a special force to dig tunnels in the future.The Enlightenment of the tunnel to Li Yuanhong is not something that can be achieved in a short time and a half. Therefore, Li Yuanhong just wants to think about what new buildings will be added to the system after upgrading to level 4. When Li Yuanhong opened the list of buildings, he found that in addition to the buildings that could be upgraded, there was a new building: the library.

"Library: a place for hero skills research and learning.

The inheritance of any knowledge is inseparable from the contribution of the library. Heroes can sort out their skills (not magic) in the library and form a written record. Heroes who have not learned such skills can learn relevant skills through the library, or upgrade their existing skills. But when a hero chooses a skill, he must choose it according to his own actual situation. Everyone has limited energy and can learn limited skills. Once he / she exceeds his / her energy online, he / she cannot learn new skills.

The library can also collect the existing knowledge, and the system will automatically organize the relevant skills

Li Yuanhong was a little excited when he saw the building. It was totally against the weather. If he sorted out the trap technique, many people could learn from it in the future. So it would be much easier for him to trap the zombie at any time and place. However, Li Yuanhong turned to think that it would be a trouble if he had a powerful skill acquired by his enemy. It seems that the library should be a key protective building in the future. However, when Li Yuanhong saw the last note, his eyes lit up. It seemed that there was a place to put the books he had collected before.

Li Yuanhong did what he said and did. He chose the address and built the library directly. This is a building that looks like the temple style of ancient Athens. It has two floors in total. It is composed of cream white marble outside. It is simple and generous, and gives people a solemn and solemn feeling. Li Yuanhong strode up the stone steps, pushed open the heavy wooden door and walked in.

After entering the gate, I saw a service desk, but now there is no one in the service desk, and there is a bar beside it. Obviously, permission is required to pass. Of course, this restriction is invalid for Li Yuanhong. Enter a very open hall through the bars. There are reading rooms on both sides of the hall. There are tables and chairs for reading in the reading room. There are also rows of bookshelves. But now the bookshelves are empty. In front of the hall, there is a staircase leading to the second floor. Li Yuanhong goes up the second floor. The whole second floor is a large reading room, but here are all electronic reading rooms. There are many small partitions. Each partition has an e-reader. However, this e-reader is not a traditional LCD reading screen, but a virtual three-dimensional electronic reading screen, accompanied by voice and virtual animation demonstration. It is estimated that this is the earth, although there are similar technologies, but the function is absolute Not so smart.
